> The universe is not deterministic. There is one brain state at time T, but at time T+1 there are many possible brain states, all with different possibilities. There is no proof of this. There are deterministic interpretations of quantum mechanics, for instance. Also, there is little reason to think our brains depend on quantum indeterminacy, even if it exists. After all, a brain that behaves erratically/non-deterministically is the exact opposite of useful. Once you learn how to walk, you want to be able to rely on that ability. Once you learn what food is, you don't want to erratically start eating rocks or twigs. Non-determinism in the brain would be selected against, not selected for. Flexibility would be selected for, but flexibility can be deterministic.
