 By ‘normative unity’, Witt means the following: given our social roles and social position occupancies, we are responsive to various sets of social norms. These norms are “complex patterns of behaviour and practices that constitute what one ought to do in a situation given one’s social position(s) and one’s social context” (Witt 2011a, 82). The sets of norms can conflict: the norms of motherhood can (and do) conflict with the norms of being an academic philosopher. However, in order for this conflict to exist, the norms must be binding on a single social individual. Witt, then, asks: what explains the existence and unity of the social individual who is subject to conflicting social norms? The answer is gender.
