I develop an egalitarian account of what's objectionable about coercion. The account is rooted in the idea that certain relationships, like those of master to slave or lord to peasant, are relationships of subordination or domination. These relationships are morally objectionable. Such relationships are in part constituted by asymmetries of power. A master subordinates a slave because the master has more power over the slave than vice versa. Coercion is objectionable, I argue, because it creates such asymmetries of power and (...) so creates relationships of subordination. This account, moreover, illuminates what's wrong with blackmail, exploitation, withholding aid, and compulsion. (shrink)
