Abstract

Aristotle's pupil Theophrastus sharpened the claim that happiness requires external goods as well as virtue, a claim prominently denied by the Stoics. Their position that virtue is sufficient for happiness requires revision of the content of happiness and adjustment of our attitudes to premature death and many other matters. The strain put on our concept of happiness is, however, greatly alleviated by the Stoic theory of preferred indifferents, which allows things other than virtue to have value of a different kind, as the material on which virtuous activity is exercised.
