Explore "The Theory of Moral Sentiments" by Adam Smith on Textopian. Read with annotations and highlights.
The man who acts according to the rules of perfect prudence, of strict justice, and of proper benevolence, may be said to be perfectly virtuous. But the most perfect knowledge of those rules will not alone enable him to act in this manner: his own passions are very apt to mislead him: sometimes to drive him and sometimes to seduce him to violate all the rules which he himself, in all his sober and cool hours, approves of. The most perfect knowledge, if it is not supported by the most perfect self-command, will not always enable him to do his duty.
Some of the best of the ancient moralists seem to have considered those passions as divided into two different classes: first, into those which it requires a considerable exertion of self-command to restrain even for a single moment; and secondly, into those which it is easy to restrain for a single moment, or even for a short period of time; but which, by their continual and almost incessant solicitations, are, in the course of a life, very apt to mislead into great deviations.
