Outra do Hume


"Hume's quotation is from a famous passage discussing the "motivating influence of the will" in hisTreatise on Human Nature and reads in full:

Reason is, and ought only to be the slave of the passions, and can never pretend to any other office than to serve and obey them. (T 2.3.3 p. 415)

The context is his discussion of what is sometimes called "moral psychology", the study of how we are motivated to act morally. In particular, he raises a question about the role of practical reason in moral motivation. Hume vehemently opposes the view, held by philosophers before him (and after him), that to act morally is have a rational grasp of moral truths. He defends an instrumental conception of practical reason, according to which the role of reason is only to find out which means helps achieve a given goal. Reason (or the intellect) plays no part in determining the goals. Our goals are set exclusively by what Hume calls the passions and what today is most often called desires.

Desires cannot be evaluated as true or false or as reasonable or unreasonable - they are "original existences" in our mind and arise from unknown natural causes. We cannot be criticized rationally for our desires (As Hume remarks, it is "not contrary to reason to prefer the destruction of the whole world to the scratching of my finger" (p 416)).

Reason is the slave of the passions in the sense that practical reason alone cannot give rise to moral motivation; it is altogether dependent on pre-existing desires that furnish motivational force. For Hume, this is not a fact we should lament (as moralists do) but a basic fact about our psychology."
