A consciousness without volition is a contradiction in terms. Not only is it psychological suicide for a human to accept that he has no control over his future and other humans have no control over theirs, but it is philosophical suicide. But perhaps the strongest ammunition against the strict determinist's position is the fact that it does not accurately reflect modern science. We see from quantum fact that indeterminism is the rule in the micro world. That is, our universe is a mixture of determinism and indeterminism.
Philosophy requires neither, but it does require causality.
But how could this be. Suppose in one an electron goes left and in the other right. In other words, Quantum Mechanics provides a refutation to the claim that science has demonstrated determinism. What I am claiming is that strict determinism can no longer claim any scientific support for its view, and it never had any philosophic support. Man's nature includes his free will.
