Logic & Life

Predicate Logic is an abstraction of ordinary language mostly suitable for ordinary day problems. Also mostly adequate for mathematics. But we should not take it as absolutely correct. It seems to cause confusion when we think about quantum mechanics. We also have some problems thinking about purpose, free will, intentionality, etc. We don’t yet know the ultimate laws of the universe, and, even if we did, the complexity of the ultimate constituents would prevent us applying them in most every day circumstances. I agree with Daniel Dennett and Jerry Fodor (I believe) that Folk Psychology is the best we can do in ordinary life circumstances. Though we can try to understand the brain etc, I don’t expect that to help making everyday decisions.
