Audi's aim in Means, Ends, and Persons is to introduce an ethics of conduct in which treatment of persons features as a central case. The approach to conduct is inspired by Kant, and there are moments of explicit contact, but this book is not meant to be a work of Kant scholarship. The method of argument consists largely in laying out a system of distinctions that are illustrated and defended by simple, familiar examples. Audi's approach here is a continuation of the common-sense intuitionism he advocates in prior work.
