The '''''Metaphysics of Morals''''' ({{langx|de|Die Metaphysik der Sitten}}) is a 1797 work of [[political philosophy|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 [[Right|rights]], and the ''Doctrine of Virtue'', dealing with ethical [[Virtue|virtues]].

In this work, Kant develops the political and ethical philosophy for which the ''[[Groundwork of the Metaphysics of Morals | 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]].<ref>Gregor, Mary J. (1996) "Translator's note on the text of The metaphysics of morals". In ''Practical Philosophy''. The Cambridge Edition of the Works of Immanuel Kant, pp. 355.</ref>

== General Structure of the Work ==
The work is divided into two main parts, the ''Rechtslehre'' and the ''Tugendlehre''. [[Mary J. Gregor]]'s translation (1991) explains these German terms as, respectively, the ''Doctrine of Right'',<ref>''Rechtslehre'' has also been translated as the ''Science of Right'' (Hastie) or the ''Metaphysical Elements of Justice'' (Ladd).</ref> which deals with the rights that people have, and the ''Doctrine of Virtue'', which deals with the virtues they ought to acquire. The ''Doctrine of Right'' also deals with required actions concerning the external relationships between people and the ''Doctrine of Virtue'' also deals with the internal requirements that characterize moral action and duty. 

== Summary ==
The ''Doctrine of Right'' is grounded in [[republicanism|republican]] interpretation of origins of political [[community]] as [[Civil_society#Early modern history|civil society]] and establishment of [[positive law]]. Published separately in 1797, the ''Doctrine of Right'' is one of the last examples of [[classical republicanism]] in political philosophy.<ref>[[Manfred Riedel]], ''Between Tradition and Revolution: The Hegelian Transformation of Political Philosophy'', Cambridge 1984.</ref> The ''Doctrine of Right'' contains the most mature of Kant's statements on the peace project and a system of law to ensure individual and public rights. It expounds fundamental and coercively enforceable principles of external conduct between people, foremost among them being the universal principle of right which states: {{Blockquote|text=Any action is ''right'' if it can coexist with everyone's freedom in accordance with a universal law, or if on its maxim the freedom of choice of each can coexist with everyone's freedom in accordance with a universal law.<ref>Gregor, Mary J. (1996) "The metaphysics of morals". In ''Practical Philosophy''. The Cambridge Edition of the Works of Immanuel Kant, p. 387.</ref><ref>Kant, MS 6:230.</ref>}}

It also discusses property rights, punitive justice, as well as state and cosmopolitan rights.

The ''Doctrine of Virtue'' further develops Kant's ethical theory, which he had already laid the foundation in the ''[[Groundwork of the Metaphysics of Morals]]'' (1785) and the ''[[Critique of Practical Reason]]''. It develops Kant’s conception of virtue and expositions of particular ethical duties we have as rational human beings. Kant particularly emphasizes treating humanity as an end in itself. The duties are analytically treated by Kant, who distinguishes duties towards ourselves from duties towards others. The duties are further classified as perfect duties and imperfect duties. Kant thinks imperfect duties allow a ''latitudo'', i.e., the possibility of choosing maxims. The perfect duties instead do not allow any ''latitudo''. Kant uses this distinction in discussing some of the duties that were shown as examples in the ''[[Groundwork of the Metaphysics of Morals | Groundwork]]'' in more detail (viz., not lying, not committing suicide, cultivating one's talents, and being beneficent toward others). He also discusses particular duties that were not mentioned in the ''Groundwork'' such as the duties of gratitude<ref>Kant, MS 6:454-456.</ref> and not being servile (falsely humble).<ref>Kant, MS 6:434-437.</ref>

Thus, Kant distinguishes "Virtue" and "Right": the "Doctrine of Right" contains rights as perfect duties towards others only.

==Influence==
In the English-speaking world, the ''Metaphysics of Morals'' (1797) is not as well known as Kant's earlier works, the ''Groundwork of the Metaphysics of Morals'' (1785) and the ''[[Critique of Practical Reason]] (1788),'' but it has experienced a renaissance through the pioneering work of [[Mary J. Gregor]].<ref>See in particular her 1963 book, ''Laws of Freedom''.</ref>
