In the area of metaphysics Faye defends the possibility of backward causation in his book The reality of the future (1989).
In contrast, he holds that we need to invent abstract concepts in order to be able to talk, say, about identity over time.
But where Bohr rejected representationalism with respect to the quantum formalism and regarded quantum theory as a tool for prediction, Faye has later advocated the view according to which the basic laws of nature properly understood are explicit language rules.
However, parts of the pragmatism and naturalism that form the back-bone of Faye’s own philosophy may be traced back to his understanding of Bohr.
Within the philosophy of mind, Faye has explored how we can understand consciousness from the evolutionary-naturalistic program he also pursues in his work on metaphysics.
