Metaphysics of Morals

Overview
The Metaphysics of Morals (German: Die Metaphysik der Sitten) is a 1797 work of political and moral philosophy by Immanuel Kant. It is also Kant's last major work in moral philosophy. The work is divided into two sections: the Doctrine of Right dealing with political rights, and the Doctrine of Virtue dealing with ethical virtues.
In this work, Kant develops the political and ethical philosophy for which the Groundwork and the Critique of Practical Reason provide the foundation.
The Doctrine of Right was first published separately around January 1797, and the Doctrine of Virtue in August of that year. Kant made a second edition with slight revisions in 1798, which include adding an appendix responding to a review of the Doctrine of Right by Friedrich Bouterwek.

All theories in which the ultimate standard of institutions and rules of action was the happiness of mankind, and observation and experience the guides (and some such there have been in all periods of free speculation), are entitled to the name Positive, whatever, in other respects, their imperfections may be.
