Hume: Moral Expressivism

Hume is believed by many to hold an emotivist thesis, according to which all expressions of moral judgements are expressions of moral sentiments. However, most specialist scholars of Hume either deny that this is Hume's position or believe that he has failed to argue convincingly for it. I argue that Hume is an emotivist, and that his true arguments for emotivism have been hitherto overlooked. Readers seeking to understand Hume's theory of moral judgements have traditionally looked to the first section (...) of Book 3 of his Treatise, which discusses the relation between morality and reason. I argue that there is evidence elsewhere which better supports Hume's emotivist thesis. Hume's arguments for emotivism focus more on the causes of moral sentiments than on their relation to reason or belief, and he argues that moral sentiments are such as to arise whenever we contemplate morally relevant objects. He also holds that the presence of moral sentiments precludes any possibility of moral belief, because moral beliefs could only be less vivid copies of moral sentiments, and these cannot simultaneously exist. Hume concludes that all moral judgements must be expressions of sentiments. (shrink)

I suggest that Kantian ethics, that is, the ethics of the mature Kant, that of Thomas Nagel, Karl-Otto Apel and Onora O'Neill, is not the caricature of an "engineering" approach in normative ethics that Lecaldano wants to fight in his war on deontological ethics. The ethics of Kant and the Neokantians can be for a consequentialist ethic a more fearsome and interesting adversary than such targets as "common-sense morality", non-existent "dogmatic intuitionism" invented by Sidgwick, non-existent "Catholic morality" that Lecaldano tends (...) to choose as privileged adversaries as if there were no more serious opponents to criticize for those who had good arguments to criticize them.
