Henry Sidgwick arrives at a dualism of these things by examining contradictions between utilitarianism and rational egoism. Bernard Williams argues that only internal versions of these things are valid, (15[1]-5[1])and that morality (15[1])imposing external ones of these things (-5[1])onto a person is baseless. (-5[1])A primary variety of these things is defined in terms of a pro-attitude (-5[1])and a belief about an action in Donald Davidson’s essay Actions, (-5[1])[these things], (-5[1])and (*) Causes. (-5[2])These (-5[1])things are the first title entity in a work exploring the repugnant conclusion (10[1])and (-5[1])the issue (-5[1])of non-identity; (10[1])that work (-5[1])by Derek Parfit (-5[1])is titled for these things and persons. (10[1])David Hume critiques moral (10[1])theories by asserting (10[1])that this thing (10[1])is a “slave (10[1])to the passions.” (10[3])For (10[1])10 points, (10[2])a critique (10[1])of what concept’s (10[2])pure form (10[6])titles (10[1])a work (10[1])by Immanuel (10[1])Kant?
