To just say that “now has nothing to do with the truth value of past-tense propositions” is to assume the point of debate. Your claim in effect just dismisses presentism, which claims that ‘now’ does have something to do with propositional truth-grounds.


No, it doesn't dismiss presentism - I've reconverted back to presentism today. But it does deny your particular form of presentism. I'm saying that it is possible to have presentism *without* grounding the truth-value of past- and future-tensed statements in the present. The more I think about it, the more sensible that seems to me! What is grounded in the present is how we know the truth value of past- and future-tensed statements, not the actual truth values themselves.

Tom said...
"Now" provides the necessary context in which propositions of all tenses are asserted at all and from which the whole question of ‘grounding’ arises. So “now” does seem to have a good deal to do with propositions (their assertion and meaning).


Now provides the context in which they are asserted, yes, and therefore the context in which we have to evaluate whether they are true or false. Obviously, if I want to know whether Caesar lived now, I have to examine presently existing evidence, I can't go back in time and have a look. But that does *not establish* that the truth-value of past-tensed propositions is grounded in the present.

Tom said...
I don’t see what restriction this places on omnipotence. To say God “changes the present” is to say he makes it true that what is now obtaining is not in fact now obtaining, which is self-contradictory.


No, that's misleading. That's not what I mean by "changing the present" obviously, if that were what I meant, then nobody could change the present at all in any way. What I mean is God acting to alter states of affairs, as we all do all the time, but in such a way as to eradicate something from the past - see my "second objection".

Tom said...
All I’m saying is that God cannot act in the present to change what defines THAT present moment. It “is” what it is. By the time God acts in response to the present moment, the moment is gone.


Then I agree with you, but that doesn't affect anything we've been arguing about!

Tom said...
This is my interest in presentism also. And while there is surely work that presentists have to do here, it seems just as sure that the answer is not found in supposing the past really does exist somewhere apart from both its impact in shaping the present (including God’s memories). This is the problem. If you want to say the past really exists somewhere as the grounds of past-tense statements presently spoken AND that this past, these grounds, exists absolutely apart from the present state of reality (which you do when you claim “now” has nothing to do with past-tense propositions and isn’t the grounds of past-tense propositions), then where or when would you suggest the past exists (remember, “exists” is a present tense verb)?


These are good arguments, although there might be possible responses to them. But since I've reconverted to presentism, that is unnecessary to explore. I'm not saying that the past exists anymore in any sense. What I am saying, is that the truth value of past-tensed statements is grounded in what happened in the past, not the present. So there is no way of knowing whether a past-tensed statement is true or not, except by examining the present. But that has nothing to do with its truth-value.

Tom said...
Albert, I take Presentism to be the belief that "there are no actual but non-present objects or states of affairs." You're saying there are such objects or states of affairs, correct?


I was but I'm not anymore. Sorry! Look on it this way: you've convinced me, sort of.

Hi Albert-

 

I was able to download sever interesting articles (pro and con) about Presentism by just typing “presentism” on Google’s search line. I wanted to pass one such paper on to you. I think I found this by typing “defending presentism” on the search line. It’s a paper by Ned Markosian (Western Washington University) entitled “A Defense of Presentism.” A different version of the same paper is found in Dean Zimmerman’s (ed) Oxford Studies in Metaphysics, vol. 1 (2004). It’s an interesting paper. I didn’t know, for example, that one common objection to Presentism is the claim that it’s incompatible with the Special and General theories of Relativity. But that’s easily answerable. Anyhow, check it out if you can.

 

In the meantime, Alan and Albert, what do you think of this (not a syllogism but perhaps the component of one):

 

1 Statements have meaning

2 The meaning of a statement is its proposition

3 The truth of a proposition is grounded in the correspondence that obtains between its meaning (language asserting some state of affairs) and reality

4 Temporality (or tense) is an irreducible part of the meaning of propositions positing contingent states of affairs

5 If (4), then no past-tense proposition and present-tense proposition can have the same meaning

6 If (5), then no past-tense proposition and present-tense proposition can posit the same state of affairs

7 If (6), then no past-tense proposition and present-tense proposition can have identical grounds for truth-value (since truth value of a proposition [which is the meaning of a statement asserting some state of affairs] is grounded in the reality of the states of affairs posited; different states of affairs posited, different grounds for truth)

 

Example: “Socrates is a philosopher” and “Socrates was a philosopher” have different meanings (obviously!). And if the meaning of a statement is the proposition it posits, then these statements posit different propositions. If they posit different propositions, then they cannot be said to share the same grounds (states of affairs) for their truth values.

 

There’s just no getting around the reality of tense. There’s no meaning (for contingent propositions at least, maybe all propositions) apart from tense. If there’s no meaning apart from tense, then all propositions (positing contingent state of affairs) are tensed. And if propositions of different tense necessarily have different meanings, then they must have different grounds for their truth values. So the past-tense “Socrates was a philosopher” cannot have as its truth-grounds the same state of affairs that grounds “Socrates is a philosopher.” This is not to say the truth value of “Socrates is a philosopher” and the truth value of “Socrates was a philosopher” are not logically related. The former cannot have been true while the latter be false, for example. But this is not to say the grounds of the former (Socrates’ being present and being a philosopher) is the grounds of the latter. On the contrary. If the grounds of the former obtains, then “Socrates is a philosopher” is true and “Socrates was a philosopher” is false. Likewise, it must be the case that if whatever grounds “Socrates was a philosopher” (Socrates’ having been present and having been a philosopher, or whatever else it is) obtains so as to render the claim true, then the truth grounds for the former (“Socrates is a philosopher”) cannot be said to obtain and it is false, in which case the two cannot share identical truth grounds.

 

Here’s a different way to pose it, Albert. If “Socrates was a philosopher” shares the same truth grounds as “Socrates is a philosopher” then must they not both share the same truth value? It certainly seems so. But they obviously cannot both be true (though they can both be false!)…

 

--------------------BREAK IN POSTING WHILE TOM CHASES A RABIT DOWN A DIFFERENT PATH-------------------

 

Oh my. They can both be false but can’t both be true? So they are contrary propositions? No. They can only be properly contrary (on the Square) if they make claims about the same state of affairs, which means the same tense. “S is a philosopher” and “S was a philosopher” must posit different propositions and have different truth grounds or else they’re ability to be both false but not both true would mean they’re properly contrary propositions. Hmm. What’s that tell us Alan? We previously agreed that “was” and “was not” and “is” and “is not” make their propositions contradictory, while “will” and “will not” are contrary. But surely “Socrates is a philosopher” has a present-tense contrary. What would that be, “Socrates is not a philosopher”? Isn’t that it’s contradictory if “is” and “is not” are contradictory? I think there’s something else we’re not figuring in. Can a proposition have more than one contrary, one of its own tense and others in other tenses? Hmmm.

 

Here are two present-tense props:

 

The present King of France is bald.

The present King of France is not bald.

 

We talked about this a long time ago. Given that these are “is” and “is not” props, must we conclude that they’re contradictory? We seem to have agreed in the paper that “is” and “is not” are contradictory. But that would mean both these propos cannot be false, which in fact they are and which fact suggests they’re contrary. Maybe there’s more to contradictoriness and contrariness than the mere presence of “is” and “is not,” for the above propositions about the King of France attribute in the present contradictory predicates about a subject that is not in fact present. The “not” is more properly conceived as prefacing “bald” and not “is.” So maybe framing the entire debate in terms of “was/was not,” “is/is not,” and “will/not not” is problematic, unless one remembers that the “not” in each case supervenes over what follows (some predicate) and not over the “was” or “is” itself. Maybe saying “is bald” vs “is not-bald” or “is philosopher” vs “is not-philosopher” is where it’s at, so that what makes present-tense propositions contrary or contradictory includes MORE than just the presence of “is” or “is not” (as the props about the King of France show). The subject and not just the predicate goes into determining whether a proposition is contrary or contradictory. Were France to presently have a king ruling, then the two propos “he is bald” and “he is not bald” would be contradictory props (for “bald” and ~“bald” are contradictory factors and all else is equal). One would have to be true and the other false. But for the predicate alone to determine whether or not the entire proposition is contradictory, the subject posited by this present-tense prop must presently obtain (and likewise in past-tense props). Maybe that’s it.

 

I got off subject a bit. But I thought it interesting that “Socrates was a philosopher” and “Socrates is a philosopher” may both be false but cannot both be true. This just shows how indispensable tense is to the meaning of a proposition. One could not place seemingly similar props of different tense (i.e., props that are identical except for their tense) on the Square and expect to apply the rules of logic throughout. It won’t work. Logically relating props (on the Square) requires that they share TENSE, which just goes to show that different TENSE means different MEANINGS means different PROPS means different GROUNDS for truth-value. “Socrates was a philosopher” cannot have as its grounds for truth Socrates’ actually being present and actually being a philosopher. If that were the grounds, the prop would be false.

 

Come on Alan.

I'll definitely have a look at Markosian's paper. Yes, the Relativity objection is a common one, but I agree that it's not convincing.

I agree with your points, I just don't think they affect the argument. When you say that "no past-tense proposition and present-tense proposition can have identical grounds for truth-value", that is true, but doesn't prove your point. The state-of-affairs that grounds the truth value of a past-tensed proposition was, on my view, a past state-of-affairs, and the state-of-affairs that grounds the truth value of a present-tensed proposition is a present state of affairs. Since one is past and the other is present, it is logically impossible for them to be the same state of affairs. I'm not denying the reality of tense; and neither are you.

But I think that you and Alan have abandoned the correspondence theory of truth. You only think that a statement is true because it corresponds with the state of affairs it describes, if it is a present-tensed statement. If it is a past- or future- tensed statement, then you think it is true or false for other reasons, not because it corresponds with the state of affairs it describes. That is where I think you are going wrong.

Let me put it this way. The tense of a proposition relates to, is a component of, the state of affairs that the statement asserts. Just as the spatial location where the proposition asserts something to be the case, is a component of the description of the state of affairs in question. So in general, a proposition explicitly or implicitly says:

At time T in location S state-of-affairs X obtains (or obtained, or will obtain).

And I think the correspondence theory of truth requires that this statement is true IF AND ONLY IF, at time T, in location S, state-of-affairs X obtains (or did obtain, or does obtain).

In other words, present conditions are *irrelevant* to the truth-value of anything except present-tensed propositions.

Tom said...
If “Socrates was a philosopher” shares the same truth grounds as “Socrates is a philosopher” then must they not both share the same truth value?


But they don't share the same truth grounds. Neither you nor I think that. "Socrates was a philospher" is true if *in the past* the state of affairs of Socrates being a philosopher obtained. "Socrates is a philosopher" is true if *in the present* that state of affairs obtains. But these two are not the same truth grounds!

Tom said...
We previously agreed that “was” and “was not” and “is” and “is not” make their propositions contradictory, while “will” and “will not” are contrary.


But this is what I am now disputing. I am saying that "will" and "will not" are contradictories. But that doesn't entail a settled future, because the grounds for the truth of either "will" or "will not" is *what happens in the future, at the time in question*.

Let me put it this way. I previously stated, I think correctly, that propositions do not "exist". They can be true or false, but they don't "exist". Neither do they have temporal or spatial location. You can't say "the proposition that 2+2=4 is in Australia". Neither does it have any temporal location. It just is either true or false. The very idea that something can be "true now" or "false now" is incoherent, except if the proposition is ambiguous and doesn't specify a time for the state-of-affairs being asserted, in which case saying something is "true now" is just a way of filling in the meaning of the proposition.

Expressing this another way: The tense of a proposition is a component of its meaning (it is internal), not external (so that a statement cannot be "true now" but "false later" ).

This does not affect Alan's square of opposition in substance at all, but it does affect how it should be expressed. The way to solve the problem is to tack onto each statement the preceding phrase, "It can presently be known that". Hence:

"It can presently be known that S will obtain" is the CONTRARY of "It can presently be known that S will not obtain".

"It can presently be know that S might obtain" is the SUBCONTRARY of "It can presently be known that S might not obtain"

and so forth around the square.

By doing this, the correspondence theory of truth is saved, and the problem of God being able to change the past is solved.

All with theistic presentism and an open future! cheers

This is fun.

 

You owe me big-time Alan!

 

Humphrey: I agree with your points, I just don't think they affect the argument.

 

Tom: I’ll try to show how it does (from my point of view at least).

 

Humphrey: When you say that "no past-tense proposition and present-tense proposition can have identical grounds for truth-value", that is true, but doesn't prove your point. The state-of-affairs that grounds the truth value of a past-tensed proposition was, on my view, a past state-of-affairs, and the state-of-affairs that grounds the truth value of a present-tensed proposition is a present state of affairs.

 

Tom: OK, I understand your explanation to amount to the claim that “Socrates is a philosopher” and “Socrates was a philosopher” do in fact share the same truth grounds in spite of your claiming they don’t. The state of affairs (SOA) which grounds the former is Socrates’ being present and being a philosopher. Fine. But when you say the truth grounds of the latter is, on your view, a “past SOA,” what, pray tell, would that SOA be if not Socrates’ being present and being a philosopher? Just because you call a “past state of affairs” that which grounds “Socrates was a philosopher” and call a “present state of affairs” that which ground(ed) “Socrates is a philosopher” doesn’t mean the two props have different grounds for their truth value. In other words, from my point of view, what you’re here calling the present tense state of affairs that grounded “Socrates is a philosopher” and the past tense state of affairs which grounds “Socrates was a philosopher” are in fact the same state of affairs. That’s what I’m talking about. If you agree that “Socrates was a philosopher” has as its ontological grounds for truth an SOA other than that SOA which grounds “Socrates is a philosopher,” then you can’t claim that a past tense SOA is what grounds the former, that THAT SOA is in fact what grounded the latter when it was true. If you agree that the two have different grounds for their truth, then the only possible grounds for the truth of “Socrates was a philosopher” is a presently obtaining state of affairs.

 

Humphrey: Since one is past and the other is present, it is logically impossible for them to be the same state of affairs.

 

Tom: Right. So why are you then attempting to ground the truth value of “Socrates was a philosopher” is the same past tense (relative to the proposition) SOA that grounded “Socrates is a philosopher” when it was true?

 

Humphrey: But I think that you and Alan have abandoned the correspondence theory of truth. You only think that a statement is true because it corresponds with the state of affairs it describes, if it is a present-tensed statement. If it is a past- or future- tensed statement, then you think it is true or false for other reasons, not because it corresponds with the state of affairs it describes. That is where I think you are going wrong.

 

Tom: Well, actually not. Alan and I agree that past- present- and future- tense statements are true of false if the proposition they posit obtains when the statement is asserted. What we’re saying is that what propositions “posit” they posit when they’re asserted regardless of whether the refer to the past, present, or future.

 

All the correspondence theory of truth claims (I think) is that a statement is true iff the proposition it posits obtains, that is, if it’s MEANING obtains. And the meaning of the past tense “Socrates was a philosopher” requires that something now obtain, that is, there must be some reality, something to which the statement points which can serve as grounds for its truth claim. It’s correspondence to REALITY that this theory of truth requires, right? Well, in what sense doe the past obtain, or exist, or in what sense is it “real’? You have to show in what sense the past is REAL apart from any consideration or reference to the present if you want to justify that claim that what grounds past-tense propositions is past-tense SOAs (viz., SOAs that once obtained but do not now obtain) and not present-tense SOAs (SOAs that presently obtain). From my point of view, past-tense SOAs are what grounded present-tense propositions positing those SOAs when those SOAs were actual. They can’t ground past-tense propositions ‘about those events’ when those events do not obtain. Something else that obtains presently must ground these past-tense props.

 

Humphrey: Tom said: ”If ‘Socrates was a philosopher’ shares the same truth grounds as “Socrates is a philosopher” then must they not both share the same truth value.” But they don't share the same truth grounds. Neither you nor I think that.

 

Tom: I don’t think they share the same grounds for truth, but it seems to me that your view entails that they do share the same grounds. See my opening comment above.

 

Humphrey: "Socrates was a philospher" is true if *in the past* the state of affairs of Socrates being a philosopher obtained. "Socrates is a philosopher" is true if *in the present* that state of affairs obtains. But these two are not the same truth grounds!

 

Tom: To me this looks like both “Socrates is a philosopher” and “Socrates was a philosopher” share the same truth grounds. I put in bold italics what suggests this to me about your view. True, you’re standing in what was the present beside the grounding SOA and pointing to it and in the other you’re standing in what is now the present and pointing to it. But you’re pointing to the same SOA. If you’re not, then you shouldn’t have any trouble with what Alan and I are saying, for all we’re saying is that the past-tense “Socrates was a philosopher” has as its grounds for truth some state of affairs OTHER than the past state of affairs that grounded “Socrates is a philosopher” when that proposition was presently true. What SOA could Alan and I be pointing to? Only some presently obtaining SOA. There is no other option.

 

Humphrey: Tom said: ”We previously agreed that ‘was’ and ‘was not’ and ‘is’ and ‘is not’ make their propositions contradictory, while ‘will’ and ‘will not’ are contrary.” But this is what I am now disputing. I am saying that "will" and "will not" are contradictories. But that doesn't entail a settled future, because the grounds for the truth of either "will" or "will not" is *what happens in the future, at the time in question*.

 

Tom: Two things about the future. I’m assuming you agree that future objects do not exist in the present. So, in what sense can non-existent objects, and non-actual states of affairs, serve as grounds for the correspondence that is supposed to account for truth at all? Secondly, if “will not” is the contradictory of “will,” what are the contraries of these propositions?

 

Humphrey: Let me put it this way. I previously stated, I think correctly, that propositions do not "exist". They can be true or false, but they don't "exist".

 

Tom: This is very strange. Just what “is” true if that which is claimed to be true (the proposition) does not exist? To what are you attributing truth in this case?

 

Humphrey: Neither do they have temporal or spatial location. You can't say "the proposition that 2+2=4 is in Australia".

 

Tom: Well, you picked a necessary state of affairs (2+2=4), and necessary states are timelessly true. We’ve been focusing on contingent states of affairs (which by definition do obtain at some times and not at others). But in a sense you’re right. I wouldn’t say propositions have physicality as such. But since propositions don’t exist apart from the statements that express them, and statements are asserted in time and space, why can’t it be true that it’s true in Australia that 2+2=4? The meaning of 2+2=4, which is the proposition, obtains in Australia. It’s “in” Australia, if you will. What is true at all is true everywhere when it’s true, and false everywhere when it’s false.

 

Humphrey: Neither does it have any temporal location. It just is either true or false. The very idea that something can be "true now" or "false now" is incoherent…

 

Tom: For being incoherent, believing that propositions are either “now true” or “now false” makes a lot of sense. And for being coherent, your claim doesn’t really communicate much to me. But don’t mind me, Albert. I’m hard-headed. I’m just wondering, if propositions are never true or false “now,” then what account can you give of their correspondence to reality? Must propositions correspond or not to states of affairs they posit?

 

Humphrey: "It can presently be known that S will obtain" is the CONTRARY of "It can presently be known that S will not obtain".

 

Tom: I thought you said “will” and “will not” are contradictories. But in any case, here you plant temporality, or tense, smack in the heart of your account of propositional truth. But this contradicts your claim immediately above that it’s incoherent to claim a proposition is “now true” or “now false.” If propositions cannot “now” be either true or false, then what does it mean to claim that we can “presently know (i.e., presently know it’s true) that S will obtain”?

 

Humphrey: "It can presently be know that S might obtain" is the SUBCONTRARY of "It can presently be known that S might not obtain" and so forth around the square. By doing this, the correspondence theory of truth is saved and the problem of God being able to change the past is solved.

 

Tom: When was God’s being able to change the past a problem? I don’t concede that this ever was a problem with Presentism.

 

That’s it Alan! It’s way beyond me now.

 

And thanks Humphrey for hanging in there with me. In truth, I’m now very confused about what it is you believe. You affirm the correspondence theory of truth, affirm that states of affairs either obtain or not, that states of affairs are the grounds for truth, but deny that truth supervenes a tensed reality (in saying propositions are never true or false at some particular time), but claim we can “presently” (i.e., “now”) know the truth that S will obtain (among other truths we can “presently” know).

 

I’m totally lost…and lost “now”!

 

Tom

OK, guys, I've been out of this for a bit. Don't have a lot of time right now, but I'll jump in where I left off.
 
HB: There is an intuitive concept that the truth value of a past-tensed statement should be determined by whether the past event really, truly, happened or not, not on whether God remembers it. In other words, if a past-tensed statement concerns an event that occurred at t=T-3, where t=T is the present time, then that statement is true if and only if when t was T-3, the state of affairs in question obtained. 
 
Alan: I completely agree with the idea that "if a past-tensed statement concerns an event that occurred at t=T-3, where t=T is the present time, then that statement is true iff when t was T-3, the state of affairs in question obtained". Nothing I have said implies that this is not the case. But it is also the case that the past-tense statement is true at T iff God remembers the event's having occurred at T-3. There are three notionally distinct but referentially equivalent ways of describing the same present states of affairs: (a) The past-tense statement's being true at T. (b) The event's having occurred at T-3. And (c) God's remembering the event's having occurred at T-3.
 
Now, you seem to want to say that the past-tense statement is true at T not primarily because the event's having occurred at T-3 now obtains, but because of the event's occurring at T-3. To that I answer both Yes and No, depending on the type of primacy that's in view. The actual occurring of the event in the past is historically primary. It is because of the occurring of event at T-3 that it is now true that the event occurred at T-3. But the event's having occurred at T-3 is semantically and (given truth as correspondence) ontologically primary. It is because the event has obtained that the past-tense statement is now true.
 
HB: There is no need to refer to God's memory or present states of affairs or whatever.
 
Alan: There is for the presentist, unless the presentist is prepared to give up the correspondence theory of truth.
 
HB: If the truth value of past-tensed statements is grounded in present states of affairs, then an alteration in present states of affairs could change the truth value of past-tensed statements, i.e., change the past. But I think it is logically impossible to change the past, no matter what you do to the present.
 
Alan: This follows only if those aspects of the present that ground the present truth of past-tense statements are subject to change. There is no need for the presentist to agree with that. And so presentism does not imply that the past can be changed.
 
HB: If God chooses to forget that X occurred, then the truth-value of "X-occurred" would therefore become FALSE. Since omniscience requires only that God knows all truths, the fact that he did not remember the event anymore would not affect his omniscience, because, as a matter of fact, it would now be the case that the event did not occur! So God could, in fact, alter whatever aspect of the past he liked without this affecting his omniscience.
 
Alan: A clever argument! It hinges on the assumption that the only reason why it might not be possible for God to forget is that He is omniscient. You recognize this when you consider whether God's goodness (rather than His omniscience) might rule out His being able to forget. But it seems to me that this gets things backwards. It is not that God can't forget because He is omniscient. Rather, He is omniscient, in part, because He can't forget. The former supervenes on the latter, not vice-versa. I'll try to explain what I mean.
 
The past historically grounds (i.e., gives rise to, develops into, etc.) the present (including God's memories). The present semantically and metaphysically grounds truth (including present truths about the past). So God's being omniscient--his knowing all and only truths--is historically grounded in the past. He remembers things having happened because they have happened. And since the past cannot be changed on pain of contradiction--what has happened cannot not have happened--so neither can God forget.
 
What I think you miss, HB, is that the presentist sees two distinct dimensions to the grounding of present truths about the past. There is the diachronic dimension, which refers to the historical development of the past into the present in virtue of which a statement can be true about the past. And there is the synchronic dimension, which refers to the present conditions (past traces, inc. God's memories) that ground the presentness of the statement's truth about the past.
 
Tom: We’re asking what “grounds” (present tense verb) past-tense propositions, not what “grounded” (past-tense verb) past-tense propositions. We can’t take “now” out of the equation.
 
Alan: Right on, Tom!
Well, I've gotta run. I'll try to catch up on the thread tomorrow.

Alan: Now, you [Humphrey] seem to want to say that the past-tense statement is true at T not primarily because the event's having occurred at T-3 now obtains, but because of the event's occurring at T-3. To that I answer both Yes and No, depending on the type of primacy that's in view. The actual occurring of the event in the past is historically primary. It is because of the occurring of event at T-3 that it is now true that the event occurred at T-3. But the event's having occurred at T-3 is semantically and (given truth as correspondence) ontologically primary. It is because the event has obtained that the past-tense statement is now true.

 

Tom: This is what I was less aptly trying to get at also. Even for present-tense props positing presently obtaining states of affairs there will be past-tense states of affairs that in a sense are primary to, or ground, the present state of affairs (in the sense that the present wouldn’t be what it IS had the past not been what it WAS). As I said, God’s decision to create the world ultimately grounds all contingent states of affairs, but that decision is not THE truth grounds for propositions about contingent states of affairs not positing God’s having decided to create. This kind of relationship obtains between Socrates’ being present and being a philosopher (when he was alive) on the one hand, and the past-tense “Socrates was a philosopher” on the other. The latter past-tense prop can’t now be true if the former—now non-existent—state of affairs had not obtained. But this doesn’t make the former state of affairs the truth grounds of the latter prop. The former isn’t irrelevant by any means, but it’s not primary in the sense required by the grounding relation. Since the former is non-existent, it can’t be the state of affairs that grounds (present-tense verb) “Socrates was a philosopher.” And if correspondence requires some state of affairs to which props correspond, there has to be some presently obtaining state of affairs that qualifies as THE grounds for “Socrates was a philosopher.” Presentists don’t all agree on just how best to account or describe that state of affairs, but they do agree that the present must be grounding such props.

The state of affairs (SOA) which grounds the former is Socrates’ being present and being a philosopher. Fine. But when you say the truth grounds of the latter is, on your view, a “past SOA,” what, pray tell, would that SOA be if not Socrates’ being present and being a philosopher? Just because you call a “past state of affairs” that which grounds “Socrates was a philosopher” and call a “present state of affairs” that which ground(ed) “Socrates is a philosopher” doesn’t mean the two props have different grounds for their truth value.


Yes, it does! The grounds for something being true is not just that a particular SOA obtains, but that it obtains *at the particular time at which the proposition asserts it to obtain*. If you construe SOA to exclude reference to time, then SOA is incomplete as a grounds for the truth of any proposition. In other words, when you say "Socrates being present and being a philosopher" grounds the truth of the statements, I think you are wrong, you have not completely specified the grounds for their truth. The complete grounds for the truth of the past-tensed version is "Socrates being present and being a philospher IN THE PAST". The complete grounds for the truth of the present-tensed version is "Socrates being present and a philosopher IN THE PRESENT". These just ain't the same grounds for truth.

This is required by the correspondence theory of truth. Part of the correspondence in question is TEMPORAL and SPATIAL correspondence, not just local state-of-affairs. It is being asserted that "at time T and spatial location S state-of-affairs X obtains". The very use of tense implies a TEMPORAL reference is being asserted for the SOA. That is a part of the grounds of truth.

Part of the problem here is ambiguity about the term "state-of-affairs". If we included temporal location in what we mean by "state-of-affairs", would that help clarify things? So Socrates presently being a philosopher is a different state-of-affairs to Socrates was a philosopher, because they occur at different times? This is purely a definitional issue, of how you define "state-of-affairs", it doesn't affect the argument at all. The point is that time of occurrence is part of the *meaning of a proposition*, it is a part of what the proposition asserts.

Tom said...
Well, actually not. Alan and I agree that past- present- and future- tense statements are true of false if the proposition they posit obtains when the statement is asserted. What we’re saying is that what propositions “posit” they posit when they’re asserted regardless of whether the refer to the past, present, or future.

All the correspondence theory of truth claims (I think) is that a statement is true iff the proposition it posits obtains, that is, if it’s MEANING obtains.


But part of the meaning is *the temporal location*. And I think that what you say entails that you hold to the correspondence theory of truth *only for the present*, not for the past and future. For example, take the statement that "Caesar crossed the Rubicon". Suppose that the only remaining traces of this in the present are (a) God remembers it happening, and (b) and ancient text somewhere that describes it. What you are saying, then is that the truth of p1="Caesar crossed the Rubicon" is grounded in the truth of p2="God remembers Caesar crossing the Rubicon" and p3="there is a manuscript describing Caesar crossing the Rubicon". But the problem is that p2 and p3 are patently obviously different states of affairs to Caesar crossing the Rubicon. God remembering Caesar crossing the Rubicon is not the same thing as Caesar crossing the Rubicon. A manuscript is not the same thing either. But for the correspondence theory of truth, the thing that grounds the statement must be THE ACTUAL STATE OF AFFAIRS DESCRIBED ASSERTED IN THE STATEMENT, not anything else, even if that "else" is necessarily connected to the state of affairs described. Let me try and explain further.

Whatever is the grounds of truth for a proposition, is the MEANING of the proposition. I think you agree with this, given your statement. But on your theory, p1 has exactly the same grounds for truth as p2 and p3. But if that is true then p2 and p3 must MEAN THE SAME THING, EXACTLY as p1. p1 is just a different way of saying p2 and p3. But that obviously isn't true. Saying "God remembers Caesar crossing the Rubicon" has a different meaning to "Caesar crossed the Rubicon"; that is intuitively obvious! Same with the manuscript. Since they have different meanings, they can't have the same grounds for truth.

Tom said...
You affirm the correspondence theory of truth, affirm that states of affairs either obtain or not, that states of affairs are the grounds for truth, but deny that truth supervenes a tensed reality (in saying propositions are never true or false at some particular time), but claim we can “presently” (i.e., “now”) know the truth that S will obtain (among other truths we can “presently” know).


Partly right and partly wrong. I'll go through each point for you:

1. Affirm the correspondence theory of truth - yes.
2. Affirm that states of affairs either obtain or not - at any given time, yes.
3. Affirm that states of affairs are the grounds for truth - no, states of affairs and the time at which they occur are the grounds for truth.
4. Deny that truth supervences a tensed reality - not sure precisely what you are saying. I think that tense is part of the meaning of propositions. Does that mean I deny that truth supervenes a tensed reality? Could I say that you deny that truth supervenes states-of-affairs, because you think that states-of-affairs are part of the meaning of the proposition?
5. Claim that we can presently know the truth that S will obtain - no, absolutely not. I deny that we can know that S will obtain (except where it relates to the part of the future which is settled, of course).

Alan said...
Now, you seem to want to say that the past-tense statement is true at T not primarily because the event's having occurred at T-3 now obtains, but because of the event's occurring at T-3. To that I answer both Yes and No, depending on the type of primacy that's in view. The actual occurring of the event in the past is historically primary. It is because of the occurring of event at T-3 that it is now true that the event occurred at T-3. But the event's having occurred at T-3 is semantically and (given truth as correspondence) ontologically primary. It is because the event has obtained that the past-tense statement is now true.


I don't quite know what to make of this, because as far as I can understand it I agree with it, but I think its supposed to be saying something different to what I believe. So maybe I haven't understood something!

Alan said...
There is for the presentist, unless the presentist is prepared to give up the correspondence theory of truth.


The correspondence theory of truth does not require that a proposition refer to or be grounded in any presently existing states of affairs. Why should it? If a statement asserts something about a presently non-existing state-of-affairs (i.e. the past or the future), then why should it require an existing state-of-affairs to ground it?

Alan said...
This follows only if those aspects of the present that ground the present truth of past-tense statements are subject to change. There is no need for the presentist to agree with that. And so presentism does not imply that the past can be changed.


Even if we accept that the "imprint of the past" on the present cannot be changed, this still doesn't establish your argument. Let's call a past-state-affairs having occurred X and the present-state-of-affairs that is its "imprint" Y. Even if I accept your argument here, all you have established is that Y being the case logically necessitates that X was the case. But that just doesn't prove that Y being the case is the grounds of truth for X having being the case. This was the point of my "Marving the Martian argument". Consider:

p1: "A closed figure with three straight sides is drawn on the table".
p2: "A closed figure with straight sides and three enclosed angles is drawn on the table".

If p1 is true, this logically entails that p2 is true, and vice-versa. But the grounds for truth of these two statements are not the same. p1 is true because the closed figure has three straight sides. p2 is true because the closed figure has three enclosed angles. These are different grounds for truth, although the truth of one entails the truth of the other. To say that, say, p2 being the case is the grounds of truth for p1, involves abandoning the correspondence theory of truth. The correspondence theory of truth requires that the specific state-of-affairs described be the grounds of truth for the statement.

Alan said...
What I think you miss, HB, is that the presentist sees two distinct dimensions to the grounding of present truths about the past. There is the diachronic dimension, which refers to the historical development of the past into the present in virtue of which a statement can be true about the past. And there is the synchronic dimension, which refers to the present conditions (past traces, inc. God's memories) that ground the presentness of the statement's truth about the past.


This is the centre of the whole thing. If the grounds for a statement's truth are presently the synchronic dimension, then there is no diachronic dimension, at least not that can be talked about. How can I make any statement about the diachronic component on your view? Suppose I say, "look, I'm not talking about the present imprint, but Caesar really, truly did cross the Rubicon way back then". On your view, despite all appearances, this statement corresponds to something present. By referencing it to the present, making it correspond to the present, its meaning is in reality only a meaning about the present, not about the past. The diachronic component would have to be "passed over in silence".

My view is that the diachronic component is what grounds the truth of past-tensed statements. That seems to be demanded by the correspondence theory of truth, and seems plain common sense. That does not exclude a synchronic component; we can still talk about the present imprint of the past. But it just avoids confusing the past with the present imprint of the past.

Tom said...
And if correspondence requires some state of affairs to which props correspond, there has to be some presently obtaining state of affairs


No. The correspondence theory of truth requires some state of affairs to which props correspond, but it does not require that this has to be a *presently obtaining* state of affairs.

I feel like I'm muddying the waters!

 

HB: The grounds for something being true is not just that a particular SOA obtains, but that it obtains *at the particular time at which the proposition asserts it to obtain*.

 

Tom: I'm slow, but in what sense does the past exist or obtain (present tense verb)? This is what I’m looking for. In what sense does Socrates’ being a philosopher obtain (present tense verb) to ground “Socrates was a philosopher”? Your present tense use of "obtain" is confusing me I think.

 

HB: If you construe SOA to exclude reference to time, then SOA is incomplete as a grounds for the truth of any proposition. In other words, when you say "Socrates being present and being a philosopher" grounds the truth of the statements, I think you are wrong, you have not completely specified the grounds for their truth.

 

Tom: Actually I did, or at least meant to. Socrates’ being present either obtains or does not obtain at any time one posits this SOA. I am including tense. I love tense! ;o)

 

HB: The complete grounds for the truth of the past-tensed version is "Socrates being present and being a philospher IN THE PAST".

 

Tom: Then when, pray tell, does the SOA Socrates’ being present and being a philosopher in the past obtain? In the past or in the present? See, by fixing “in the past” to the entire italicized SOA, the only time at which this state of affairs can obtain is subsequent to the time Socrates actually lived. So the state of affairs you give (in my view) is equivalent to what Alan and I are calling Socrates’ having been present and having been a philosopher which is precisely what Presentism claims is the grounds of “Socrates was a philosopher.”

 

Did you mean to write: "The complete grounds for the truth of the past-tense version is 'Socrates' being present and being a philosopher' [end quote] in the past"?

 

HB: The complete grounds for the truth of the present-tensed version is "Socrates being present and a philosopher IN THE PRESENT". These just ain't the same grounds for truth.

 

Tom: Then you shouldn’t have any problem agreeing with the presentist claim that the SOA that grounds “Socrates was a philosopher” is not a past-tense non-existent SOA but rather Socrates’ having been a philosopher (which is not a past-tense non-existent SOA at all).

 

Maybe we’re talking past each other, I'm not sure.

 

HB: This is required by the correspondence theory of truth. Part of the correspondence in question is TEMPORAL and SPATIAL correspondence, not just local state-of-affairs. It is being asserted that "at time T and spatial location S state-of-affairs X obtains".

 

Tom: Obtains? That’s a present-tense verb. If you advocated the static theory of time this would make sense I suppose. But if the past doesn’t exist (on the dynamic theory of time), doesn't 'obtain', what sense does it make to say, per your formula here, that “On November 2, 1963 Kennedy IS BEING assassinated”?

 

HB: The very use of tense implies a TEMPORAL reference is being asserted for the SOA. That is a part of the grounds of truth.

 

Tom: I thought tense was an indispensable part of the meaning of a proposition too, but in your last post you said it was incoherent to say that a proposition is true or false “now.” Sounded to me like you were tossing tense out as part of meaning, correspondence, or truth grounds.

 

HB: Part of the problem here is ambiguity about the term "state-of-affairs". If we included temporal location in what we mean by "state-of-affairs", would that help clarify things?

 

Tom: It’s not only the time at which Kennedy was assassinated (1963) that’s part of the meaning of the proposition, it’s also the time at which the person makes the claim which is part of the meaning.

 

HB: So Socrates presently being a philosopher is a different state-of-affairs to Socrates was a philosopher, because they occur at different times? This is purely a definitional issue, of how you define "state-of-affairs", it doesn't affect the argument at all. The point is that time of occurrence is part of the *meaning of a proposition*…

 

Tom: The SOA Socrates’ being present and being a philosopher can only obtain at some ‘present’ moment. That's the only time one can "be." One can't "be" in the past or future. Socrates’ having been present, which above you seem to agree is what grounds “Socrates was a philosopher” cannot obtain at the same time Socrates’ being present and being a philosopher obtained. I think we agree on this. So if Socrates’ having been present grounds “Socrates was a philosopher,” and tense is part of the meaning of this proposition, and Socrates’ having been present cannot obtain when Socrates’ being present and being a philosopher obtained (i.e., in the past), then there's only one temporal location at which to locate the grounding SOA Socrates’ having been present, and that is the present.

 

HB: Tom said...Well, actually not. Alan and I agree that past- present- and future- tense statements are true of false if the proposition they posit obtains when the statement is asserted. What we’re saying is that what propositions “posit” they posit when they’re asserted regardless of whether the refer to the past, present, or future. All the correspondence theory of truth claims (I think) is that a statement is true iff the proposition it posits obtains, that is, if it’s MEANING obtains.

 

But part of the meaning is *the temporal location*.

 

Tom: Yes! And the temporal location of the meaning of “Socrates was a philosopher” is the present, not the past. This meaning, the meaning of THIS proposition, cannot obtain (or be temporally located) in the past when Socrates was actually present and was actually a philosopher, for at that temporal location the meaning of “Socrates was a philosopher” would be false. Why? Because its meaning cannot be said to obtain at that time. “Socrates was a philosopher” can only be true because its meaning, its proposition, is temporally located at the time subsequent to Socrates' actual existence, viz., when the past-tense proposition is asserted.

 

HB: And I think that what you say entails that you hold to the correspondence theory of truth *only for the present*, not for the past and future.

 

Tom: I’m an amateur, but as far as I can tell correspondence is a relation, and relations cannot (so far as I understand) obtain between actual and non-actual objects. This point is actually raised (unsuccessfully) by philosophers in objection to Presentism. Since relations can only be said to obtain between actual objects or states of affairs, philosophers object that presentists cannot account for any grounding relation that obtains between the propositions spoken in the present and Socrates so as to make “Socrates was a philosopher” true. I was just reading one criticism of presentism to the effect that presentists can only logically maintain that present-tense propositions are true since that’s the only time “relations” (and so grounding) can be said to obtain. But if what grounds past- and future-tense props obtains now, then the grounding relation does obtain between actualities.

 

HB: For example, take the statement that "Caesar crossed the Rubicon". Suppose that the only remaining traces of this in the present are (a) God remembers it happening, and (b) and ancient text somewhere that describes it. What you are saying, then is that the truth of p1="Caesar crossed the Rubicon" is grounded in the truth of p2="God remembers Caesar crossing the Rubicon" and p3="there is a manuscript describing Caesar crossing the Rubicon".

 

Tom: Personally, I think the SOA Caesar’s having crossed the Rubicon actually obtains. I'm less convinced that God's memories actually 'ground' past-tense propositions.

 

HB: But the problem is that p2 and p3 are patently obviously different states of affairs to Caesar crossing the Rubicon. God remembering Caesar crossing the Rubicon is not the same thing as Caesar crossing the Rubicon. A manuscript is not the same thing either.

 

Tom: True.

 

HB: But for the correspondence theory of truth, the thing that grounds the statement must be THE ACTUAL STATE OF AFFAIRS DESCRIBED ASSERTED IN THE STATEMENT…

 

Tom: I agree. Where we differ is in what we understand to be the ACTUAL state of affairs posited by a past-tense proposition. I don’t see that the ACTUAL state of affairs posited by “Caesar crossed the Rubicon” is Caesar’s crossing the Rubicon. How could it be since this is not an ACTUAL state of affairs when we assert “Caesar crossed the Rubicon”? Some other state of affairs must be grounding this prop.

 

HB: Whatever is the grounds of truth for a proposition, is the MEANING of the proposition.

 

Tom: I think not. The meaning of a statement or assertion IS the proposition. I think you earlier pointed this out when you quoted Alan. And propositions have grounds for their truth-values. So how can the meaning of a statement be both the proposition itself and the grounds for the proposition’s truth? That would reduce to a proposition being the grounds for its own truth.

 

HB: Saying "God remembers Caesar crossing the Rubicon" has a different meaning to "Caesar crossed the Rubicon"; that is intuitively obvious! Same with the manuscript. Since they have different meanings, they can't have the same grounds for truth.

 

Tom: I’m agreeing. But this doesn’t mean the truth grounds for “Caesar crossed the Rubicon” is not a present state of affairs, say, Caesar’s having crossed the Rubicon.

 

HB: I'll go through each point for you:

 

1. Affirm the correspondence theory of truth - yes.

2. Affirm that states of affairs either obtain or not - at any given time, yes.

 

Tom: I was following you on (2) until you added “at any given time.” Do you mean to say that past states of affairs actually obtain ("obtain" is a present tense verb)? Future states of affairs actually obtain? Or are you agreeing (and as I would say) that the only time at which a state of affairs can be said to “obtain” is now?

 

HB: 3. Affirm that states of affairs are the grounds for truth - no, states of affairs and the time at which they occur are the grounds for truth.

 

Tom: Not sure I get what you mean. It sounds like you’d answer my immediately preceding question by saying past states of affairs actually obtain (but I can hardly believe you believe this), or else (if the past does NOT obtain) “Socrates was a philosopher” could have no grounds for its truth in your approach.

 

HB: 4. Deny that truth supervences a tensed reality - not sure precisely what you are saying. I think that tense is part of the meaning of propositions. Does that mean I deny that truth supervenes a tensed reality? Could I say that you deny that truth supervenes states-of-affairs, because you think that states-of-affairs are part of the meaning of the proposition?

 

Tom: I don’t think states of affairs are part of the meaning of propositions. I think a statement’s meaning IS its proposition and that states of affairs on the other hand are what GROUND the truth-values of propositions. So I wouldn’t say that the states of affairs, the grounds, are part of the meaning. I think correspondence either obtains or does not obtain between the meaning (i.e., proposition) posited by statements and states of affairs in the real world.

 

HB: 5. Claim that we can presently know the truth that S will obtain - no, absolutely not. I deny that we can know that S will obtain (except where it relates to the part of the future which is settled, of course).

 

Tom: Then you agree that we can presently knkow the truth that S will obtain (if S will obtain is true, obviously). What else did you mean when you said “The way to solve the problem is to tack onto each statement the preceding phrase, ‘It can be presently known that S will obtain’”? Now, see, I don't take that on explicitly because the fact is that the only time at which we can know ANYTHING is the present. So what is added to our knowing that "S will obtain" is true by saying we can presently know that "So will obtain" is true? It's superfluous. The only time we can know anyting is presently.

 

HB: The correspondence theory of truth does not require that a proposition refer to or be grounded in any presently existing states of affairs. Why should it? If a statement asserts something about a presently non-existing state-of-affairs (i.e. the past or the future), then why should it require an existing state-of-affairs to ground it?

 

Tom: Because the past and future do not exist. And non-existent objects cannot be said to stand in any relation to what does exist. The proposition “Socrates was a philosopher” exists. Socrates doesn’t exist. Correspondence is a relation. Relations obtain only between existent objects or states of affairs. So the non-existent Socrates cannot himself constitute the grounding relation. But Socrates' having existed CAN constitute this grounding relation since it is an existing state of affairs.

 

Gotta go. I’m tired! I'm probably complicating things the more I talk (sorry if that’s the case Alan).

Alan and Humphrey-

We got off, perhaps unwisely, by starting the discussion about Presentism by talking about ‘grounding’. Maybe that’s not the way to go. I mean, perhaps one should decide on reasons other than grounding schemes whether or not one is a presentist (reasons like cosmology, theory of time, relativity, etc.). Once decided, then the presentist (or nonpresentist) should let the chips fall where they may with respect to grounding. Grounding follows cosmology (in other words). It doesn't make sense to first adopt a grounding theory and THEN go look for a cosmology or ontology to fit it, since the latter is far more important. I’m saying that our view of what grounds truth-value shouldn’t be what determines whether one adopts presentism or not. That’s backing into the adoption of an important view, not a wise way to adopt or reject presentism.

Here’s a paragraph from Ned Markosian’s (Western Washington University) article “A Defense of Presentism”:

“Presentism is the view that only present objects exist. According to Presentism, if we were to make an accurate list of all the things that exist – i.e., a list of all the things that our most unrestricted quantifiers range over – there would be not a single non-present object on the list. Thus, you and I and the Taj Mahal would be on the list, but neither Socrates nor any future grandchildren of mine would be included. And it’s not just Socrates and my future grandchildren, either – the same goes for any other putative object that lacks the property of being present. All such objects are unreal, according to Presentism. According to Nonpresentism, on the other hand, non-present objects like Socrates and my future grandchildren exist right now, even though they are not currently present. We may not be able to see them at the moment, on this view, and they may not be in the same space-time vicinity that we find ourselves in right now, but they should nevertheless be on the list of all existing things.”

By “present” he means temporally present. Now it seems to me, Humphrey, that you agree (though I’m not sure) that past objects are not temporally present. Nor are future objects temporally present. Isn’t this enough to establish you as a presentist? Our disagreements over truth grounding seems to be a different issue.

Tom

PS Just to clarify, in the previous post I spoke of relations not obtaining between actual and non-actual objects. Markosian refers to these as temporally present and temporally non-present objects. Same thing.

Hey Humphrey-

In addition to that article by Ned Markosian, the following article is also good (and is available online): “Presentism and Ontological Commitment” by Theodore Sider (Syracuse University), Journal of Philosophy 96 (1999). I’ve only scanned it (and noted that he misses the insight we make regarding “might and might not” being on equal ontological footing with “will,” but hey, nobody’s perfect), but enough to enjoy it.

Peace,
Tom

It doesn't exist and it doesn't obtain. It existed (past tense) and it obtained (past tense). And it is the fact that it obtained (past tense) that grounds past-tensed propositions.

Tom said...

That's easy: in the past.

Tom said...
See, by fixing “in the past” to the entire italicized SOA, the only time at which this state of affairs can obtain is subsequent to the time Socrates actually lived.


No. That's not when it obtains, that's when it is asserted. Whenever something is asserted, the time and place can be specified either in absolute or relative terms. I could say, for instance, "in 500 BC Socrates being a philosopher obtained". That would specify the time in absolute terms. Or I could say, "in the past, Socrates being a philosopher obtained". That would specify the time in relative terms: the time is specified *relative to the time of the speaker*. I can do this with space as well. I can say, "George Bush is in the United States" (absolute), or "George Bush is to the north of here" (relative). But where and when the thing obtains is different to where and when it is asserted, which only affects the meaning for relative tempero-spatial locations.

Tom said...
Then you shouldn’t have any problem agreeing with the presentist claim that the SOA that grounds “Socrates was a philosopher” is not a past-tense non-existent SOA but rather Socrates’ having been a philosopher (which is not a past-tense non-existent SOA at all).


It is a past-tensed *presently* non-existent SOA. The SOA did exist, but it doesn't anymore. What's the problem?

Obtains? That’s a present-tense verb. If you advocated the static theory of time this would make sense I suppose. But if the past doesn’t exist (on the dynamic theory of time), doesn't 'obtain', what sense does it make to say, per your formula here, that “On November 2, 1963 Kennedy IS BEING assassinated”?


The problem here is just grammar. I used the present-tense "obtains" in a sense relative to the time T and spatial location S. But just to make you happy, I have reworded things:

Part of the correspondence in question is TEMPORAL and SPATIAL correspondence, not just local state-of-affairs. It is being asserted that "at time T and spatial location S state-of-affairs X obtains/obtained/will obtain (substitute appropriate verb according to value of T relative to current time)".

I don't say that Kennedy is being assassinated. I say that he was assassinated, and that this is true because in the past, a certain SOA obtained (past tense). Not because of anything, whatsoever, in the present.

Tom said...
I thought tense was an indispensable part of the meaning of a proposition too, but in your last post you said it was incoherent to say that a proposition is true or false “now.” Sounded to me like you were tossing tense out as part of meaning, correspondence, or truth grounds.


No, no, no: it's *you* who's tossing it out as the grounds of truth, by grounding the truth of everything in the present and shifting tense to apply to the truth-value rather than the meaning. Tense is *internal* and is part of the situation being asserted, part of the meaning, not *external* and relating to the time at which the truth-value holds.

Tom said...
It’s not only the time at which Kennedy was assassinated (1963) that’s part of the meaning of the proposition, it’s also the time at which the person makes the claim which is part of the meaning.


No, it isn't. You think that because of your confusion between what I've called the internal and external application of tense. When a person asserts something has *nothing whatsoever* to do with the meaning; except that when temporal or spatial location are specified in relative terms, it is necessary to know when and where the speaker is to evaluate the sense *relative to the speaker*.

Tom said...
The SOA Socrates’ being present and being a philosopher can only obtain at some ‘present’ moment. That's the only time one can "be." One can't "be" in the past or future.


I don't know what to make of this statement. Either you're making the rather obvious point that the verb "be" is present tense, and hence can no more refer to the past or future than the word "dog" can refer to a cat. Or you're trying to say that the past and the future don't presently exist, which I agree with. Or you're trying to say that the past did not exist and the future will not exist, which is bizarre.

Tom said...
Yes! And the temporal location of the meaning of “Socrates was a philosopher” is the present, not the past.


No, it's the past, and that seems to me as obvious as the nose on my face. Suppose somebody said to you, "Socrates was a philosopher". You reply, "oh I understand! You're telling me something about present states-of-affairs, right". Any normal person is going to think you are crazy!

Tom said...
I’m an amateur, but as far as I can tell correspondence is a relation, and relations cannot (so far as I understand) obtain between actual and non-actual objects.


Yes, but I'm saying that if a relation *did obtain* or *will obtain*, that is enough for grounds of truth. It doesn't have to obtain presently. It is true to say that relations have to involve actual SOA, but an SOA that was actual or an SOA that will be actual will do, it doesn't have to be an SOA that is actual. I think you over-reacted against the criticism of presentism you mention.

Tom said...
The meaning of a statement or assertion IS the proposition. I think you earlier pointed this out when you quoted Alan. And propositions have grounds for their truth-values. So how can the meaning of a statement be both the proposition itself and the grounds for the proposition’s truth? That would reduce to a proposition being the grounds for its own truth.


Here lies the heart of the problem. You are forced to distinguish the meaning of the proposition from what gives it its truth value. In so doing you abandon the correspondence theory of truth. According to correspondence theory, a proposition is true if its meaning obtains/obtained/will obtain. But that wont' do for you, because you want to ground its truth in things that presently obtain, even if its meaning says nothing whatsoever about things that presently obtain. You are attempting to hold to a correspondence theory of meaning, but not a correspondence theory of truth. But this is incoherent. The problem arises when we ask, well then, *what, precisely* is it that is true? You must answer, the presently obtaining states of affairs that ground the statement (whatever they are). If so, then that is *all that is being asserted*. Nothing is being asserted about the past or the future. In other words, you cannot separate the meaning from the grounds of truth. In correspondence theory, the grounds of truth are nothing more or less than if the meaning obtains/obtained/will obtain.

Tom said...
Personally, I think the SOA Caesar’s having crossed the Rubicon actually obtains.


OK, then Tom. You think that the present is all that exists. There must be some present state of affairs, on your theory, that grounds "Caesar crossed the Rubicon", that Caesar crossed the Rubicon "corresponds" to. So tell me, what states of affairs are these? Give me an example, if you don't like my example! Whatever example you give, it will quickly become evident that the proposition pT = "the SOA presently obtain that Tom thinks grounds Caesar having crossed the Rubicon", and pA="Caesar crossed the Rubicon", have different meanings. That they're not asserting the same thing at all; and hence they can't have the same grounds for truth.

Tom said...
I don’t see that the ACTUAL state of affairs posited by “Caesar crossed the Rubicon” is Caesar’s crossing the Rubicon. How could it be since this is not an ACTUAL state of affairs when we assert “Caesar crossed the Rubicon”? Some other state of affairs must be grounding this prop.


And as soon as you say "some other state of affairs must be grounding this prop.", you abandon the correspondence theory of truth, which requires that the actual SOA asserted must ground the prop. And the whole problem is one of your own making, because the SOA in question doesn't have to presently obtain. All that matters is that it did obtain in the past.

Tom said...
I was following you on (2) until you added “at any given time.” Do you mean to say that past states of affairs actually obtain ("obtain" is a present tense verb)? Future states of affairs actually obtain? Or are you agreeing (and as I would say) that the only time at which a state of affairs can be said to “obtain” is now?


Again, you are being mislead by focussing on the fact that English doesn't have a tenseless verb, so I have to use something to get the concept across. So let me say it this way:

I agree that SOA either obtain/obtained/will obtain at any given time (cross out whichever verb conjugation is inappropriate according in relation to the particular given time).

What is the SOA depends on what is the time. The SOA that obtained yesterday are not the same as those that will obtain tomorrow. That's my point. If you just say "SOA either obtain or not" you are only covering the present; you're saying nothing about the past or future. Nothing at all!

Tom said...
I don’t think states of affairs are part of the meaning of propositions. I think a statement’s meaning IS its proposition and that states of affairs on the other hand are what GROUND the truth-values of propositions.


What does it mean to say that a statement's meaning is its proposition? What then is the meaning of the proposition? Answer: whatever grounds it's truth-value. To go in reverse: whatever grounds the propositions truth-value, is what is being asserted to be true, is therefore what the proposition's meaning is.

[QUOTE="Tom"]Then you agree that we can presently knkow the truth that S will obtain (if S will obtain is true, obviously). What else did you mean when you said “The way to solve the problem is to tack onto each statement the preceding phrase, ‘It can be presently known that S will obtain’”? Now, see, I don't take that on explicitly because the fact is that the only time at which we can know ANYTHING is the present. So what is added to our knowing that "S will obtain" is true by saying we can presently know that "So will obtain" is true? It's superfluous. The only time we can know anyting is presently.

Yes, the only time we can know anything is presently, but knowing and truth are two different things. Knowledge is *justified true belief*. It requires more than just that the proposition in question be true. I am arguing that "either X will or X will not" is true. But we cannot presently know which of "X will" or "X will not" is true (except if something presently the case entails one or the other). What grounds the truth of whichever is true? Whatever happens in the future that they are asserting (X will) or denying (X will not).

Suppose that you say "tomorrow Humphrey will choose to buy an ice cream", and it turns out that I do, in fact, buy an ice cream. In that case, what you said was true. However (assuming that my choice is free in relation to the ice cream), the fact that it was true does not mean that you knew it. In fact, it would have been a "lucky guess". But lucky guesses don't count as knowledge.

Part of the problem is that whenever someone asserts something, they implicitly are claiming to know that it is true. This is where the confusion about statements like "X will occur" comes about, I think.

[QUOTE="Tom"]Because the past and future do not exist. And non-existent objects cannot be said to stand in any relation to what does exist.

See earlier comments. The relation in question does not have to presently hold. If it held or will hold, that is quite sufficient. The fact that a particular SOA no longer obtains, does not by any means change the fact that it did obtain. And that it did obtain, is sufficient from the correspondence point of view.

[QUOTE="Tom"]I’m saying that our view of what grounds truth-value shouldn’t be what determines whether one adopts presentism or not. That’s backing into the adoption of an important view, not a wise way to adopt or reject presentism.

Yes, that's right. You and I are both presentists, but we have different theories of grounding, which we're trying to work out. But the problem is that the theory of grounding provides a context for how you present presentism, and if your theory of grounding has flaws, then people are going to reject presentism on that basis. Just like if we present Christian doctrine in the context of Calvinist predestination, people might reject Christianity, without realising that the question of predestination is a logically distinct issue.

The issue affects how presentism should be expressed, and hence affects things like Alan's article.

By the way, to express things in Alan's terms, I would say that the truth of propositions is grounded in the diachronic, but the grounds for our knowing the truth of these propositions is in the synchronic.

Truth=Diachronic
Epistemological=Synchronic

This is the funniest conversation!

Until Alan jumps in to make sense of my buckshot (which though TRUE is still sprayed everywhere!) I suggest you read the two articles I referred to (by Markosian and Sider, both available online), take two aspirin, and then repeat to the yourself like a Hindu chanting a mantra: "Only the present is real! Only the present is real!" ;o)

Peace downunder Albert!

Hello guys-

 

Another interesting article (available online): “Presentism and Truthmaking” by Simon Keller (Boston U). It’s also in Dean Zimmerman (ed.) Oxford Studies in Metaphysics Vol. 1 (Oxford University Press, 2004).

OK Tom! I'll do the chanting you suggest if you chant the following:

"A past-tensed statement is a statement about the past"

Hey guys, I'm just wondering.  Does the basis of your paper presuppose a particular view of time i.e. linear?  Should not this have been laid out first and then the other stuff (the paper?)  Also, why should one accept this view of time as reasonable?  Thanks.

Hi Brandon-

Yeah, we go with the dynamic, linear view of time. Actually, I think this is mentioned earlier on in the paper.

We went with this view of time because IT'S THE RIGHT ONE, YOU BLAKITY-BLANK BLANK! :O)

Page 3: “The Case for a Settled Future. There are four main strategies that can be pursued to argue that the future is settled. First, one can try to show that universal determinism is true. If it is, then there is exactly one causally possible chain of events extending from the present onward, which entails a settled future. Second, one can argue for a static view of time. On such a view, the future is (tenselessly) already there and consequently settled.”

 

Page 8: “The Case for an Open Future. Of the reasons that exist for thinking the OFV is true there are perhaps four that are of significance. First, one can argue from scripture that God knows the future as partly open, and that, therefore, it really is partly open. Second, one can argue from the stochastic nature of quantum physics that the future is, in some respects, really indeterminate and therefore open. For example, many quantum physicists would say that there is no fact of the matter about what a particle in “superposition” definitely will or will not do, but only facts about what it probably will or will not do.”

 

Page 12: “As for the contingency thesis [i.e., the dynamic view of time, or the belief in future contingency], we will simply register here our conviction that it is correct….”

 

Your right, Brandon. Our paper assumes the dynamic theory of time. The paper just wasn’t the place to argue the in's and out's of such a view of time. But we do acknowledge it. And we do acknowledge that if the static view of time is correct, then presentism and open theism are false and there are no future contingencies and libertarian free will is an illusion. So for someone who holds to the static view, our paper is a flop. But for those who DO hold to the dynamic view, to genuine indeterminism, what about the logic of the open view? THAT’S where we wanted to stake our claim that the open view is the only way to uphold omniscience.

 

So do you hold to the static view of time?

 

Tom

Tommy!
How ya doin bud?  How ya doin?  Ya doin?  To tell you the truth, I'm not to sure what you mean by that.   By a static view of time.  If by that you mean the all seeing "eternal now?"  Then no.  I don't hold to that. That's bullcrap man!  biggrin But I was talking about this with someone and to quote them, they said,
 
I really believe one of our biggest stumbling blocks to understanding this is the fact that we do not know what "time" is. Is it linear? Is it _a_ dimension, or does it _have_ dimension? Is it really possible for all our possible "nows" to exist simultaneously? What is time that God could be constrained by it? What is God that he could be constrained by time? Is God "time"?
 
Well then they started getting weird on me because they then said,
There is a debatable idea held by some Hebrew scholars that God's name, JHWH, is made up of three characters that are the basis for the Hebrew words for "past", "present" and "future". (bet you thought I was going to say "Moe, Larry and Curly"!) Does God exist in what has been described as "the eternal now"? Or take that a step further, does God exist through all our _possibilities_ as well as our actualities? Probably not difficult for someone who is infinite. Has God already worked through all our possible decisions? That would explain much, such as how he knows us better than we know ourselves.
 
See, this person here is then working with a particular understanding of time that is linear i.e. past, present and future or "a linear continuum of instants."  But how does God exist through our possibilities?  Of course he could exist through our possibilities when they are settled but then they would not be possibilities now would they?  It seems he is working more from the SFV as stated at the beginning of your paper.  Should I take Alan up on reading Craig's "Time and Eternity" spiel?
 
What sayest thou?

Hey Tom,
 
Here's a paper update:
 
I received confirmation from Hasker a couple weeks ago that our paper is currently undergoing peer review. I expect we'll know whether it's going to get published or not within the next 2 to 3 months.
 
Regards,

Good news Alan. Let's all pray for Bill Hasker and his peers!
Brandon, for sure ya gotta read Craig's "God and Time." Reeeally good. He has such a great handle on that stuff.

I need your help.  I saw Pinnock this weekend.  Told him about the paper and how much I think he'd like it (like really ALOT).  I also told him I would get him a copy.  Problem is, his computer doesn't take Adobe pdf. format.  Is there any way I can get this to him?  Help me out y'all.  biggrin  Greg, Alan, Tommaaaay!

I sent it off to him in Word format. We'll see if that works.

------------------------

Brandon: I'm not to sure what you mean by that. By a static view of time. If by that you mean the all seeing "eternal now?" Then no. I don't hold to that. That's bullcrap man!

 

Tom: Yeah, you’ve got two available understandings, the “dynamic” and the “static.” The static view of time is behind the “eternal now” bull you’re talking about! The dynamic view is the view God told me was the right view! (ha ha)

 

Brandon: Well then they started getting weird on me because they then said: There is a debatable idea held by some Hebrew scholars that God's name, JHWH, is made up of three characters that are the basis for the Hebrew words for "past", "present" and "future."

 

Tom: Oooooh, that’s it. I mean, how can ya counter THAT! I heard Nixon’s name when written in Hebrew had a numeric value equal to that of the anti-Christ. Really, this is silly. Jehovah is written the three letters, true. And these letters also appear in thousands of other words. So what? I mean, if you’re debating friends who are into this, don’t waste you’re time. Find someone else to debate with!

 

Brandon: Bet you thought I was going to say "Moe, Larry and Curly"!)

 

Tom: If your friends had said Moe, Larry, and Curly I might be able to put some stoke into their view!

 

Brandon’s friends: Does God exist in what has been described as "the eternal now"? Or take that a step further, does God exist through all our _possibilities_ as well as our actualities? Probably not difficult for someone who is infinite.

 

Tom: Now why should that not be difficult for someone who is infinite? Why does being “infinite” become a blank check for some people to imagine that God does whatever pops into their heads?

 

Brandon: Has God already worked through all our possible decisions? That would explain much, such as how he knows us better than we know ourselves.

 

Tom: How stupid is God then? I mean, he has to be atemporal to know us better than we know ourselves? Can’t God know us perfectly and be temporal?

 

Brandon: See, this person here is then working with a particular understanding of time that is linear i.e. past, present and future or "a linear continuum of instants." But how does God exist through our possibilities? Of course he could exist through our possibilities when they are settled but then they would not be possibilities now would they? It seems he is working more from the SFV as stated at the beginning of your paper. Should I take Alan up on reading Craig's "Time and Eternity" spiel?

 

Tom: You can’t do better than Craig on that. He’s really good, and explains the different views really well. Then there’s that 4-views book on time also. But go with Craig. I disagreed with a few things, but I really liked him.

 

Now, I could be wrong, but the “linear” view of time is the “dynamic” view of time. To say time is “linear” is to say that one moment follows another, that subsequence is real, and the arrow of time runs in one direction from past through the present into the unformed future. But all the points of time along the “line” aren’t equally present. That’s more like the static view, which is also called the “block” theory of time. It’s all there, like a “block,” all points equally present. It sounds like your friend holds to the “block” theory.

 

Tom
