This paper presses the programmatic idea that it is fruitful to think of genders as constituted by aesthetic rational social practices; in particular, that doing so can illuminate the relation between social role and self-identity. The first part of the paper describes rational social practices, and then interprets two social-role approaches to genders in light of that description. The interpretation places the two approaches in different domains of reason, one epistemic, one practical; this makes apparent the conceptual space for a (...) model of gender roles inhabiting the aesthetic domain. The second part of the paper articulates such a model, according to which the feminine and masculine roles in a social context consist in aesthetic constraints, enablements and norms. These depend on rational, social, human-centred aesthetic practices in which gender differentiation is essential. The third part of the paper demonstrates the utility of this model by using it to explore the relation between social role and self-identity; it argues that one identifies with a gender by actively participating in the very aesthetic practices that constitute it, and so generating reasons for self-valuation. Throughout, the point is not so much to defend the specific details of the suggested views, but more to show that the idea that aesthetic practices play a significant role in constituting gender merits serious consideration.
