(Gr. hedone pleasure) "The view that happiness is the highest good. Some writers take this to designate the view that pleasure is the highest good, but that view is more properly called hedonism. Happiness and pleasure are distinct notions."
Kant was an important opponent of eudaimonism. He rejected the view that happiness is the highest good, and insisted that happiness can be an ingredient of the highest good only if it is deserved.
