Abstract
This paper argues that Hume was first and foremost a moral psychologist and a determinist, not a moralist. When confronting the fact of moral disagreement, notably in "A Dialogue" affixed to his moral enquiry, he maintained that it is not psychologically possible to approve of the conflicting norms of other cultures, except in the case of sometimes approving of individuals in other cultures for abiding by those objectionable norms rather than fomenting cultural upheaval. All cultures should nonetheless agree on the most general and fundamental moral principles as well as on most specifics. But there are non-trivial specific cases on which there will be irreconcilable disagreements, based on conflicting beliefs concerning utilities, finer matters of taste, and uncertainties over how best to maximize conflicts between the useful/agreeable and the personal/social. In these cases, we would be wise to consider whether tolerating the conflicting views of others would be more useful and agreeable than attempting to enforce conformity. Toleration is among the less obvious virtues, but it is one that experience has by now taught us to adopt, at least in certain cases
