 This entry first looked at feminist objections to biological determinism and the claim that gender is socially constructed. Next, it examined feminist critiques of prevalent understandings of gender and sex, and the distinction itself. In response to these concerns, the entry looked at how a unified women’s category could be articulated for feminist political purposes. This illustrated that gender metaphysics — or what it is to be a woman or a man or a genderqueer person — is still very much a live issue. And although contemporary feminist philosophical debates have questioned some of the tenets and details of the original 1960s sex/gender distinction, most still hold onto the view that gender is about social factors and that it is (in some sense) distinct from biological sex. The jury is still out on what the best, the most useful, or (even) the correct definition of gender is.
