Abstract
In a cryptic passage of the "Doctrine of Virtue" (§ 23), Kant underscores the relation between the two kinds of ethical duties to others, which he calls duties of love and duties of respect. The paper will explore the issues concerning this relation, and try to clarify the meaning of it for Kant’s overall account of the duties towards others. I suggest that (1) Kant thereby highlights the role of a previously unconsidered class of duties, and highlights that that novelty changes the traditional picture of other-regarding morality. (2) Most importantly, Kant shows that through their reciprocal connection both duties of love and duties of respect can be related to the obligatory end of the happiness of others.
