Abstract

I demonstrate that the two major ethical traditions agree that there are given desires which provide extra-rational practical reasons. Empiricist theories ground ethics in such desires, but the extra-rationality of this foundation appears to lead to stultifying subjectivism. Rationalist theories justify the appeal to an independent Kantian Reason as necessary to gain control over such desires. But the status of these desires as providing motivating reasons guarantees that such independent Reason can never be more than one among competing sources of practical rational motivation. ;I then argue that the generalization and extension of the epistemological argument against the given provides compelling evidence that there can be no such given desires. This argument demonstrates that episodes which can provide reasons cannot be extra-rational, indeed must be constituted through rational endorsement. This critical argument is applied to the work of Dennis Stampe and Thomas Hobbes , and extended from desires to preferences . ;In order to provide rational warrant, a desire must itself be rationally endorsed in a context of other endorsed episodes within which its own warrant is secured. There are no given desires, no extra-rational practical reasons in which the crude empiricist can ground practical reasoning. But there is also no need to postulate Reason independent of desire to gain rational control over such desires. I close by suggesting that this critical argument provides a framework for the construction of a middle ground between the two traditions which incorporates their central insights while avoiding their chronic failings
