“What are the questions that fascinate you?” “What do you want to know?”

It is a good while now—some five years—since I last published an article in Substance so I am grateful to the editors for this chance to reminisce and air a few bees in my bonnet. As it happens, that article was a piece on the realism versus anti-realism debate in philosophy of quantum mechanics, and must have struck them at the time as a bit far removed from the interests of most readers. Still, it included some lengthy passages about Derrida and a certain reading of Derrida that brought him out (wrongly, I argued) in agreement with the anti-realist position. Most likely this was why the piece went in, or perhaps just as a striking example of how erstwhile literary theorists—such as myself—were in the process of challenging orthodox ideas of disciplinary competence and scope. Anyway, it marked something of a turning-point in my own interests, which have since then focused increasingly on issues in epistemology, philosophy of science, and philosophical semantics. I have also written about philosophy of logic and, in particular, those varieties of “deviant” (or non-bivalent) logic that have been proposed as—among other things—a means of accommodating quantum phenomena such as wave/particle dualism. So probably the best I can do here is offer some account of why my thinking has moved in this more “philosophical” direction, but also some attempt to explain why it doesn’t, after all, feel like such a drastic change of interests.
