The Common Structure of Kantianism and Act-Utilitarianism

This article proposes a way of understanding Kantianism, act-utilitarianism and some other important ethical theories according to which they are all versions of the same kind of theory, sharing a common structure. I argue that this is a profitable way to understand the theories discussed. It is charitable to the theories concerned; it emphasizes the common ground between them; it gives us insights into the differences between them; and it provides a method for generating new ethical theories worth studying. The article briefly discusses the relationship between these ideas and some other recent proposals that emphasize the common ground between Kantianism and versions of consequentialism.
