This chapter explores the usage of third-person singular pronouns in English, arguing for the Sex-Tracking View, where pronouns (‘he/him’ and ‘she/her’) traditionally entail information about biological sex. Linguistic evidence supports this view, as pronouns are used consistently to denote sex in contexts involving non-human animals, suggesting that English pronouns have evolved to track biological sex rather than gender or “gender identity,” that is, one’s attitude about the sexes. I respond to objections from Michael Glanzberg and Cameron Domenico Kirk-Giannini, who propose a Gender-First View, by arguing, among other things, that their objections to the Sex-Tracking View may well confuse linguistic norms with social conventions. The chapter then transitions to normative considerations, questioning whether we should maintain the practice of sex-tracking with pronouns. Arguments in favor include the social importance of distinguishing between males and females for safety, the facilitation of sexual reproduction, and the moral implications of pronoun use as signaling acceptance or rejection of specific ideologies. However, I also consider objections to this practice: it may not affirm individuals’ attitudes about the sexes, including his own; it could be seen as exclusive; it may potentially invade privacy; and it might lead to social or professional repercussions for non-compliance. I then critically evaluate these objections.
