  However we define the class of desires that is subject to the requirement of maximization, we do not need to take those desires exactly as they are given. Many proponents of the maximizing approach suggest that an agent’s actual desires should be laundered somewhat before the demand to maximize is applied. For instance, if my desire for X is contingent on a false factual belief about the nature of X, then it is not obvious that practical reason requires that the desire be taken into account in determining what it is rational for me to do. A popular form of laundering would rule out desires of this kind, by subjecting to the requirement of maximization only those desires that would survive if the agent were factually well-informed about the objects of desire and the circumstances of action, and deliberating in a calm and focused frame of mind. Indeed, once we are in the business of laundering desires we can go still further, excluding from consideration desires that are substantively objectionable, even if they would survive the filter of corrected factual belief. To move into this territory, however, would clearly be to abandon the Humean framework of the original maximizing approach, assuming resources for the rational criticism of ends that are independent of the agent’s actual dispositions.
