In this article, I address a highly controversial question of feminist philosophy, namely, the so-called sex/gender distinction, from a Deweyan perspective. I argue that Dewey's naturalism provides useful insights for dealing with and solving the problems concerning this particular type of dualism. My argumentation unfolds in three steps. First, after having briefly introduced the meanings of the two terms, I outline two different, both unsuccessful strategies for overcoming the sex/gender distinction, namely, what I call the radical social constructionist and the nondialectical naturalist strategies. Second, I draw on Dewey's version of naturalism with the aim of conceiving of human beings as simultaneously naturally and socially constructed. Third, I sketch out the hypothesis that Dewey's way of overcoming the pernicious dichotomy between nature and society may be useful for outlining a critical metaphysics of gender.
