In this paper I contest Searle's thesis that desire-independent reasons for action - 'reasons that are binding on a rational agent, regardless of desires and dispositions in his motivational set' - are inherent in the concept of rationality. Following Searle's procedure, I first address his argument that altruistic reasons for action inhere in the concept of rationality, and then examine his argument for his more general thesis. I conclude that a viable theory of rational action would be centered, not on (...) the concept of desire-independent reasons, but rather on the concept of rational desire. (shrink)
