The desire-satisfaction theory of welfare says, roughly, that one's life goes well to the extent that one's desires are satisfied. On standard 'actualist' versions of the theory, it doesn't matter what you desire. So long as you are getting what you actually want – whatever it is – things are going well for you. There is widespread agreement that these standard versions are incorrect, because we can desire things that are bad for us -– in other words, because there are 'defective desires'. The aim of this paper is to defend the actualist desire-satisfaction theory against the problem of defective desires. I aim to show how the theory can accommodate the obvious fact that we can desire things that are bad for us. Admittedly, there are kinds of allegedly defective desire the theory cannot accommodate, but these desires, I argue, turn out not to be defective in the relevant way.

One of the most important disputes in the foundations of ethics concerns the source of practical reasons. On the desire-based view, only one’s desires provide one with reasons to act. On the value-based view, reasons are instead provided by the objective evaluative facts, and never by our desires. Similarly, there are desire-based and non-desired-based theories about two other phenomena: pleasure and welfare. It has been argued, and is natural to think, that holding a desire-based theory about either pleasure or welfare commits one to recognizing that desires do provide reasons for action – i.e., commits one to abandoning the value-based theory of reasons. The purpose of this paper is to show that this is not so. All of the following can be true: pleasure and welfare provide reasons; pleasure and welfare are to be understood in terms of desire; desires never provide reasons, in the relevant way.
