ABSTRACT
For man, the life according to intellect is best and pleasantest, since intellect more than anything else is man. This life therefore is also the happiest. But in a secondary degree the life in accordance with the other kind of virtue is happy.
(Nicomachean Ethics, 1178a6–10)Only those who are absolutely self-complete (cheng) can fully develop their nature. If they can fully develop their nature, they can then fully develop the nature of others.
