Practical Reason, Sympathy and Reactive Attitudes

Abstract

This paper has three aims. First, I defend, in its most radical form, Hume's scepticism about practical reason, as it applies to purely self-regarding matters. It's not always irrational to discount the future, to be inconstant in one's preferences, to have incompatible desires, to not pursue the means to one's ends, or to fail to maximize one's own good. Second, I explain how our response to the “irrational” agent should be understood as an expression of frustrated sympathy, in Adam Smith's sense of sympathy, rather than a genuine judgement about Reason. We judge these people because we cannot imaginatively identify with their desires and attitudes, and this is frustrating. Third, compared to the standard cognitive view, my account better explains the nature of our criticism of the “irrational,” and, by portraying “irrationality” as a cause of upset to other people, provides a better normative basis for being “rational.”.
