 Another source of dissatisfaction with Kant’s account has been with his characterization of persons and the quality in virtue of which they must be respected. In particular, Kant’s view that the rational will which is common to all persons is the ground of respect is thought to ignore the moral importance of the concrete particularity of each individual, and his emphasis on autonomy, which is often understood to involve the independence of one person from all others, is thought to ignore the essential relationality of human beings (for example, Noggle 1999; Farley 1993; Dillon 1992a; E. Johnson 1982). Rather than ignoring what distinguishes one person from another, it is argued, respect should involve attending to each person as a distinctive individual and to the concrete realities of human lives, and it should involve valuing difference as well as sameness and interdependence as well as independence. Other critics respond that respecting differences and particular identities inevitably reintroduces hierarchical discrimination that is antithetical to the equality among persons that the idea of respect for persons is supposed to express (for example, Bird 2004). Identity and difference may, however, be appropriate objects of other forms of consideration and appreciation.
