Forget God -- a belief in any transcendent property or existence or even a rejection of pure reductionism is typically greeted with a scowl and an argument which boils down to "Come on. . . . you really don't believe that."
I'm fairly sure there are professional philosophers who reject strong reductionism as a form of scientism. Don't ask me why, as I'm not trained in philosophy, and I'm told that computer people make utter dorks of ourselves when we try to talk about philosophy without training.
