Some contemporary intepreters of Kant maintain that on Kant's view fulfilling duties of virtue require doing so from the motive of duty. I argue that there are interpretive and doctinal reasons for rejecting this interpretation. However, I argue that for Kant motives can be deontically relevant; one's motives can affect the deontic status of actions.

This is the only book devoted entirely to The Metaphysics of Morals and is not just a landmark in Kant studies but also a significant contribution to contemporary moral and political philosophy.

This is the only book devoted entirely to The Metaphysics of Morals. Seventeen essays by leading contemporary Kant scholars cover such topics as Kant's views on rights, punishment, contract, practical reasoning, revolution, freedom, virtue, legislation, happiness, moral judgement, love, respect, duties to oneself, and motivation.

In this updated edition of his outstanding introduction to Kant, Paul Guyer uses Kant’s central conception of autonomy as the key to his thought. Beginning with a helpful overview of Kant’s life and times, Guyer introduces Kant’s metaphysics and epistemology, carefully explaining his arguments about the nature of space, time and experience in his most influential but difficult work, _The Critique of Pure Reason_. He offers an explanation and critique of Kant’s famous theory of transcendental idealism and shows how much (...) of Kant’s philosophy is independent of this controversial doctrine. He then examines Kant’s moral philosophy, his celebrated ‘categorical imperative’ and his theories of duty, freedom of will and political rights. This section of the work has been substantially revised to clarify the relation between Kant’s conceptions of "internal" and "external" freedom. In his treatments of Kant’s aesthetics and teleology, Guyer focuses on their relation to human freedom and happiness. Finally, he considers Kant’s view that the development of human autonomy is the only goal that we can conceive for both natural and human history. Including a chronology, glossary, chapter summaries and up-to-date further reading, _Kant, second edition _is an ideal introduction to this demanding yet pivotal figure in the history of philosophy, and essential reading for all students of philosophy.

Der Aufsatz behandelt den Zusammenhang zwischen Recht, Ethik und Moral in der MdS. Ausgangspunkt ist der Befund, daß Kants System der Pflichten in der MdS weder konsistent noch vollständig ist, weil Rechts- und Tugendpflichten, entgegen Kants Annahme, den Bereich der moralischen Pflichten nicht erschöpfen . Kants System der Pflichten beruht auf den Unterscheidungen zwischen Recht und Ethik und zwischen Legalität und Moralität. Letztere konzipiert Kant in der MdS anders als in früheren Werken, indem er sie nun auf die beiden Arten (...) der "Gesetzgebung" in Recht und Ethik und die daraus entspringenden Gesetze zurückführt . Im Zusammenhang mit der "ethischen" Gesetzgebung ergibt sich das Problem, wie es ethisch geboten sein kann, aus Pflicht zu handeln . Analog dazu stellt sich mit Blick auf die "juridische" Gesetzgebung die Frage, warum man befugt ist, andere zu rechtlichem Handeln zu zwingen. Handelt es sich um eine moralische oder eine spezifisch rechtliche Befugnis? Es zeigt sich, daß Kant zwei unvereinbare Auffassung miteinander verbindet: Aus seiner "offiziellen" Auffassung, wonach das Recht ein Teil der Moral ist, würde folgen, daß die Zwangsbefugnis im Recht moralisch gerechtfertigt werden kann. Tatsächlich ist eine solche Rechtfertigung aber nicht möglich, die "offizielle" Auffassung also unzureichend. Kant greift in der MdS aber auch mehrfach auf eine "alternative" Auffassung zurück, der zufolge das Recht als eine eigenständige Form autonomer Gesetzgebung neben der Moral steht . Dieser alternativen Auffassung zufolge, die der "offiziellen" insgesamt überlegen ist, würde die "Rechtslehre" also gar nicht in die Metaphysik der Sitten gehören. (shrink)

(Ak 10:74).[1] During the so-called ‘silent decade’ of the 1770s, when Kant was working on the Critique of Pure Reason, he promised repeatedly not only that he would soon finish that work but also that he would soon publish a “metaphysics of morals” (Ak 10:97, 132, 144).[2] Yet it was not until four years after the first Critique that Kant finally wrote a work on ethics, and even then he merely laid the ground for a metaphysics of morals by identifying (...) and establishing the supreme principle on which a system of duties would be based (G 4:392). Three years later, in the Critique of Practical Reason Kant once again dealt entirely with foundational questions in moral philosophy. Kantian ethics is primarily known, especially among English-speaking philosophers, through these two ethical works of the 1780s, neither of which contains anything like a ‘metaphysics of morals’.
