Quantum mechanics, however, throws a monkey wrench into this simple mechanical view of things.  No less a figure than Eugene Wigner, a Nobel Prize winner in physics, claimed that materialism — at least with regard to the human mind — is not “logically consistent with present quantum mechanics.” And on the basis of quantum mechanics, Sir Rudolf Peierls, another great 20th-century physicist, said, “the premise that you can describe in terms of physics the whole function of a human being … including [his] knowledge, and [his] consciousness, is untenable. There is still something missing.”

Food for thought.  Science still doesn’t have all the answers.  It is by definition always a work in progress.
