Introduction

A short book, published in Riga in 1785, that Kant wrote as groundwork for a fuller ethics; the “Metaphysics of Morals” itself followed only in 1797. After a preface come three sections. The first starts from ordinary moral understanding: only a good will is good without qualification, and an action has moral worth when done from duty, as with the shopkeeper who is honest because it is right, not because it pays. The second distinguishes hypothetical from categorical imperatives and gives several formulations of the latter, among them treating humanity always as an end and never merely as a means. The third links morality to freedom.
