Steve: Having listened to Rorty a bunch on Youtube, it cool to be able to imagine his voice saying this.

Steve: That is an interesting tidbit on Rorty. I think that saying "a true sentence was true before anybody thought it up" is an ugly way of putting it since saying so is counterintuitive for anyone who thinks that sentences don't have lives of their own independent of human beings first thinking of them. Someone could take it as a metaphysical assertion about sentences rather than a semantic notion about how the word true is used in sentences. But if we focus on not the truth of the sentence but instead on what it means to believe that the sentence is true in terms of ability to satisfy desires I think that it is not so counterintuitive. With regard to Newton's Laws before there were any humans around at all, I suppose the truth question involves imagining the possibility of time travel. I think when we imagine what was going on in terms of physics or geology or whatever before there were any people, what we are doing isn't imagining sentences floating around in space free of ourselves but imagining oureselves floating around in space to believe and disbelieve the sentences. Does that make sense? I suppose part of what James was doing was avoiding the odd metaphysical assertion about sentences having lives of their own by conflating justified belief and truth. At first I suppose he thought he was just following Pierce who had said that talk about truth is talk about belief and doubt. Truth is not the object of inquiry for Pierce. The object of inquiry is getting rid of doubts and settling on belief. It goes without saying that what one holds as justified and can find no reason to doubt is held as true, and the question of whether or not a belief in question actually IS true is exhusted by such consideration of doubts. James took this conclusion to mean that there is no practical difference between what actually is true and what is merely held to be true, so he dropped the distinction between truth and justification. James answered the question "what is truth?" as though the question had been "how can we know what assertions are true?" he was right in following Pierce to say that the second question is our only practical concern, but wrong to think that the two questions are not still different questions. He was right to think "what is truth?" is a bad question, and wrong to think that he had answered it nevertheless when he answered the question "how can we know which assertions are true?" The pragmatic answer to his question is that the only route to truth is justification, but how are the two "bridged," as you say? That is where all the controversy between pragmatists begins, doesn't it? At first it seems that Pierce was content not to connect truth and justification since truth is never the real object of inquiry. Then James jumped on Pierce's ideas and concluded that truth ought to be simply reduced to justification. Justification is the bridge.For James, verification is what MAKES a belief true. Pierce didn't like that answer at all (since many of our justified beliefs are not true) and tried fairly unsuccessfully to formulate a theory of truth consistent with his own pragmatic descriptions of belief, doubt, and inquiry. But his descriptions has already made a definition of truth unnecessary for inquiry beyond saying as Rorty did that "to say that a belief is, as far as we know, true, is to say that no other habit of action is, as far as we know, a better habit of action." This sentence says how the word "true" is used. For a pragmatist, to say how a word is used is what it is to say what a word means. There is nothing more to the meaning of the word than the pattern of usage of a word, and there is nothing more to believing an assertion than the pattern of behaviors associated with believing it. Instead of trying to bridge justification and truth, Pierce would have done well to stick with his description of truth he ended with in Fixation: "truth...is distinguished from falsehood simply by this, that if acted on it should, on full consideration, carry us to the point we aim at and not astray..." No more is needed to be able to say that truth is something we ought to want and that truth and justification have a needed connection. The sort of connection between truth and justification where beliefs justified in a certain way will always be true does not seem possible, yet we've done pretty well without such a bridge. Pierce had already argued that scientific fallibilism is the best method we have ever come up with and has done very well for us. He should have recognized that his further attempts to clarify the meaning of truth where not going to help us have more true beliefs. What do you make of this part of Pierce's Fixation of Belief? "If your terms "truth" and "falsity" are taken in such senses as to be definable in terms of doubt and belief and the course of experience (as for example they would be, if you were to define the "truth" as that to a belief in which belief would tend if it were to tend indefinitely toward absolute fixity), well and good: in that case, you are only talking about doubt and belief. But if by truth and falsity you mean something not definable in terms of doubt and belief in any way, then you are talking of entities of whose existence you can know nothing, and which Ockham’s razor would clean shave off. Your problems would he greatly simplified, if, instead of saying that you want to know the "Truth," you were simply to say that you want to attain a state of belief unassailable by doubt.
