The Ethics of Swearing: The Implications of Moral Theories for Oath-Breaking in Economic Contexts

Many readers will share the judgement that, having made an oath, there is something morally worse about consequently performing the immoral action, such as embezzling, that one swore not to do. Why would it be worse? To answer this question, I consider three moral-theoretic accounts of why it is ‘extra’ wrong to violate oaths not to perform wrong actions, with special attention paid to those made in economic contexts. Specifically, I address what the moral theories of utilitarianism, Kantianism and a new communitarian-relational principle entail for the wrongness of oath-breaking. I argue that the former two do not adequately capture why it is extra wrong to perform an immoral action that one swore not to do, but that the latter appeal to a morality of communal relationship offers a promising account.
