INTRODUCTION
intro
The essay on Progress in Virtue is one of Plutarch’s polemics against the Stoics, and is directed mainly against two of the doctrines of the Stoic philosophy. The first is that the wise man alone is virtuous, and that wisdom with attendant virtue is a sudden acquisition with no preliminary stages; the second is in a way the corollary of the first, since, if a man is not perfect (i.e. wise), it may be argued that it matters little how trivial is his imperfection and whether his faults be great or small. He that offendeth in one point is guilty of all.
intro
Against such doctrines as these Plutarch’s strong common sense revolts, and he endeavours to show not only that ethical advance is possible, but that there are plenty of signs by which it can be recognized.
