 Objectification is a perennial issue in the philosophy of sex. It originates in Kant’s moral philosophy, and many feminists have adopted its language to criticize, for example, pornography, though whereas Kant was concerned with the objectifying nature of sexual desire, feminists do not target sex as such, but only in the context of patriarchy, claiming that it involves the sexual objectification of women by men in certain contexts (see below; some claim that all heterosexual sex is poison under patriarchy, e.g., Dworkin 1987). Indeed, sexual desire might not be necessary for the claim that a woman is sexually objectified under patriarchy: a man need not sexually desire a woman to catcall her.
