Plutarch (c. 50-120)
“Moral good is a practical stimulus; it is no sooner seen, than it inspires an impulse to practise; and influences the mind and character not by a mere imitation which we look at, but, by the statement of the fact, creates a moral purpose which we form.”
- Quote by Plutarch in Parallel Lives (Life of Pericles). The edition used here is from the Harvard Classics series, edited by Charles W. Eliot, and published by P. F. Collier & Son (1909, 1937).
