A Moorean paradox of desire

Abstract

Moore's paradox is a paradox in which certain kinds of belief or assertion, such as a belief that ‘it is raining and I do not believe that it is raining’, are irrational despite involving no obvious contradiction in what is believed. But is there a parallel paradox involving other kinds of attitude, in particular desire? I argue that certain kinds of desire would be irrational to have for similar, distinctive reasons that having Moorean beliefs would be irrational to have. Hence, I argue that such desires, a desire that ‘one have a particular desire that was frustrated’ or a desire that ‘some state of affairs obtain about which one was indifferent’, are a parallel Moorean paradox of desire. I further argue that this analogous paradox has implications for practical reasoning, in particular by presenting a problem for instrumentalism about the objects of desire.
