Maybe the idea of compossibility is relevant to this discussion. Wikipedia describes compossibility as follows: "According to Leibniz, a complete indi...

Why not?

Sure, why not. I do not see why God could not work by natural means, in addition to supernatural means, to help us know what He is thinking.

Thanks. I think now is a good time to hear your critiques whenever you are ready Richard B.

Frank, Kripke's use of rigid designators is not discussed in the SEP article according to Banno. Would you object if we hear from Richard B's critique...

We are talking about possible "properties" of a thing, the referent, in this case "Nixon." Insofar as those properties are merely "possible" I don't s...

Thanks for your thorough comments earlier. I am afraid I cannot do it just with a similarly thoroughgoing reply. I do not really have any reason to ar...

This is what you said. But you presumably also agree that the same thing can have different properties over time. If the same thing can have different...

negatory Banno, not too much, the lingo is :up: :up:

extensionality lost = no referent for modal logic claims. "Necessarily all John's pets are mammals" is false, but because there is no extension to cor...

The same thing cannot have different properties at different times?

Why would God be responsible for the actions of another agent? That is, why does creation entail responsibility for the actions of another? Here is a ...

I agree with you that eternity itself is not an explainer. My understanding of Aquinas is that: even if the universe itself is eternal, if anything in...

"Worse. They're called Blue Jeans."

His point was that the intensionality of modal logic is irrelevant to the fact that possible world semantics establishes extensionality by predicates ...

But i think Banno was not making the claim that modal logic is not intensional.

1.1 -> "Modal logic, by contrast, is intensional."

And consequently sentence extensions; that is, truth value, also varies across worlds.

Your objection against possible worlds makes sense to me. Extensionality seems to require a referent of some sort; and I am not sure the article has d...

T Clark -- "Okay everyone, who wants to test out this wooden bridge I designed?" "I designed it within 6 orders of magnitude so it will either hold al...

Did you want to design bridges?

Yeah, it was Chatgpt, the machine that is built to say smart things, that's probably who messed up in this situation. I'm not complaining.

I agree with your following quotes about biological ETI: " the more rigorously we've observed the non-terrestrial universe the less we find non-terres...

:lol: :clap:

Well, how long does think ETI could survive and does he think we can make it that long?

Define "our reality." Who is us and how is "real" defined?

Based on T Clark's assertion that 1 million years for ETI to survive is "wildly optimistic" and that he "doubts we'll be around that long" I have to a...

Okay. Yeah, I was curious why an advanced alien race would decide to call it quits at the 1 million year mark. I do not think it is "wildly optimistic...

Sometimes.

Wait, what happens after 1 million years? :sweat: I do not think anyone is saying that. And pessimistic is definitely the wrong word.

Can you say what you mean by this? Do you mean a sentence with these terms cannot have a truth value, or do you mean they fail at substitutivity alway...

So I think a key parameter in making a probability calculation is the similarity of these other billion worlds to Earth. My understanding is: what is ...

:up: Got it.

Yeah I am still confused about why modal logic itself is not extensional, but possible world semantics is apparently extensional.

I see. I think my questioning about semantics in relation to logic was in reference to propositional logic that deals with formal languages only; in t...

And that is because there is no way of making sense of "necessarily" under a Tarskian interpretation and without possible world semantics.

That is, the sentence: "Necessarily, all John's pets are mammals" is not a sentence that can be parsed by a Tarskian interpretation that converts the ...

Alright, then by statement do you mean a token of some proposition in some possible world? I was thinking it is because the Tarskian interpretation of...

haha, yeah I was thinking that myself, and I think it is a good question. It would seem to have to do with the evolution of that species and how risk ...

1.2 The problem we ran into with the extensionality of modal logic concerned the fact that modal logic appeared to not be subject to classical substit...

Semantics in a logical system seems like a somewhat difficult prospect. Would be interested to hear your criticisms of Kripkean (possible world?) sema...

You are saying that a proposition is a statement that we all agree on? I have heard the term proposition applied in a more neutral sense. "The cat is ...

We do not know how life formed or whether other Earthlike planets have the conditions to enable life to form. The odds seem to be: what are the chance...

I was referring to life in our galaxy only as I think it is more likely that any first received radio signals would originate within our galaxy due to...

I think a primary factor in determining the variation in time between life on Earth compared to when life forms elsewhere would be the difference in t...

I realize this thread is not recent, but I thought I should tack my thoughts on here rather than starting a new thread. I think it is more probable th...

The introduction conceptually orients; "possible worlds" means something like - that that is opposed to the "actual world" such as a historical counte...

:up: Okay, thanks.

Okay, fair point. Supposing it is possible, the answer would seem to be that the probability of the coin being Heads is 50% or (1/2). The number of ti...
