Abstract
In Nicholas Smyth’s recent article, “When Does Self-Interest Distort Moral Belief,” he argues that self-interest undermines justification for moral belief if it justifies itself. In so doing, he opposes the standard account, which says that, to the extent that a person’s moral belief is explained by her egoistic or parochial interests, that belief is less justified. However, Smyth’s attack on the standard account, and the principle that he proposes to replace it with, do not withstand critical scrutiny, and that is what this article is intended to show. To that end, the article is divided into three sections. In the first, I explain the standard account and provide some background. In the second, I critically examine Smyth’s three arguments against the standard account. In the third, I explain and attack Smyth’s own principle. I conclude that Smyth’s principle should not be accepted, and the standard account should not be rejected, at least on the basis of Smyth’s arguments: self-interest undermines justification in general, as per the standard account, not only when it justifies itself.
