Abstract
Theories about value struggles with the problem how toaccount for the motivational force inherent to value judgments. Whereasthe exact role of motivation in evaluation is the subject of somecontroversy, it’s arguably a truism that value has something to do withmotivation. In this paper, I suggest that given that the role of motivationin ethical theory is left quite unspecific by the “truisms” or “platitudes”governing evaluative concepts, a scientific understanding of motivationcan provide a rich source of clues for how we might go about developingan empirically responsible theory of value. More specifically, I argue that naturalist hedonists should be eager to join forces with motivational science: the role of pleasure in themotivational system is such that a sound case for hedonism can be builton it.
