After reading the passage in Redeeming Science (quoted in my previous blog entry), I got to thinking about truth. Poythress’s arguments are amazingly profound for being so easily stated!
What is truth? It is, as Poythress argued, fundamentally rational. Truth is also linguistic. Therefore, a simple definition of truth might be “Propostions (ie: statments) about some object that are consonant with reality.”
This is important because truth cannot exist without language or mind. Note: reality could exist apart from these things; but truth–propositions about reality–could not.Â
If we assume, therefore, that there is no God then before the human mind sufficiently “evolved” to formulate truth concepts, there was no truth.
If this is the case, though, then we cannot argue about whether something is true before man’s thoughts. There was no truth before man invented truth through the evolution of language.
But this itself cannot be true. That’s right. It is a propostion about reality before the existence of truth. In other words, five seconds before truth was created in the form of language, it was not true (nor false) that “there is no truth.” The only way for it to be true is if there was some other mind with language that existed in order to formulate truth. But if such a mind existed, then the statement would be catagorically false to say that there was no truth at the time!
In short, the propostion “There was no truth at X” (where X can be any time, past, present, or future) can never be true. The only way it can avoid being false is if it become meaningless (ie: neither “truth” nor “falsehood” are relevant at the point).
Thus, if we argue as previously stated–”before the human mind sufficiently ‘evolved’ to formulate truth concepts, there was no truth”–we are forced to recognize that that argument is either false or meaningless.
This is the case for all historical “truths” that precede the human mind (again, assuming there is no God). It is not true that the Big Bang happened, for instance. When the Big Bang happened there was no truth, and thus there was no truth-value for the Big Bang.
But naturally we do not talk this way. Instead, we presuppose that there was truth before man came on the scene. We presuppose that it is actually true that the Big Bang happened, for instance. But in presupposing this, we must also presuppose the existence of some kind of mind and language in order to make the proposition true.
Now some may argue that this is semantics. Some may even argue that we can change it to “reality” instead. It was “reality” that the Big Bang happened, even if it wasn’t “true” per se.
But this statement about reality is itself a truth-statement, and thus this statement falls back into the same problem.
Therefore, even in speaking of “reality” before human thought, the atheist must presuppose the existence of another mind with language.
In short, the atheist is left with a problem. Either he must assert that everything pre-human intelligence is meaningless (and thus embrace radical skepticism and relativism), or he must assert that there was another mind (or minds) that existed pre-human intelligence.
This isn’t a problem for the Christian, however, as we do assert the existence of a Mind that pre-existed human consciousness.
