Single Idea 21411

[filed under theme 23. Ethics / C. Virtue Theory / 1. Virtue Theory / a. Nature of virtue ]

Full Idea

Only an end that is also a duty can be called a duty of virtue. ....[385] The necessary ends are one's own perfection, and the happiness of others.

Gist of Idea

A duty of virtue is a duty which is also an end

Source

Immanuel Kant (Metaphysics of Morals II:Doctrine of Virtue [1797], 383 Intro II)

Book Ref

Kant,Immanuel: 'The Metaphysics of Morals', ed/tr. Gregor,Mary [CUP 1991], p.188

A Reaction

So virtues are a subset of duties. I don't think an Aristotelian virtue is anything like a duty. A soldier might do his duty, with no virtue at all. An even a Kantian categorical imperative duty can be formed without right feeling or good character.
