Bill
offers an argument to the effect that truth requires God.
Among the truths there are necessary truths such as the laws of logic. Now a truth is a true truth-bearer, a true proposition, say. Nothing can have a property unless it exists. (Call this principle Anti-Meinong). So no proposition can have the property of being true unless the proposition exists. A necessary truth is true in every metaphysically possible world. It follows that a necessarily true proposition exists in every possible world including worlds in which there are no finite minds. But a proposition is a thought-accusative that cannot exist except in, or for, a mind. If there is no God, or rather, if there is no necessarily existent mind, every mind is contingent. A contradiction ensues: there is a world W such that, in W, there exists a thought-accusative that is not the thought-accusative of any mind.
Bill suggests four ways of rebutting the argument. Here is a fifth. We can deny that the laws of logic are propositions. A law of logic is more like a function that given a proposition returns a true proposition. For example:
LEM: p → p ∨ ¬p
In a world without propositions there is nothing for LEM to work on to deliver a true proposition. Bill's argument does not rule out such a world.
