[filed under theme 20. Action / C. Motives for Action / 1. Acting on Desires ]

Full Idea

One way to decide what we have normative reasons to do …is by trying to find a set of desires that is systematically justifiable, which is our best assessment of the desires we would have under conditions of full rationality.

23724 A pure desire could be criticised if it were based on a false belief [Smith,M]
23723 In the Humean account, desires are not true/false, or subject to any rational criticism [Smith,M]
23727 Expressivists count attitudes as 'moral' if they concern features of things, rather than their mere existence [Smith,M]

23730 'Rationalism' says the rightness of an action is a reason to perform it [Smith,M]
