Evil is easily discovered; there is an infinite variety; good is almost unique. But some kinds of evil are almost as difficult to discover as that which we call good; and often particular evil of this class passes for good. It needs even a certain greatness of soul to attain to this, as to that which is good.

Wisdom leads us back to childhood.

Undoubtedly equality of goods is just; but, being unable to cause might to obey justice, men has made it just to obey might. Unable to strengthen justice, they have justified might--so that the just and the strong should unite, and there should be peace, which is the sovereign good.

The strength of a man's virtue should not be measured by his special exertions, but by his habitual acts.

When we do not know the truth of a thing, it is good that there should exist a common error which determines the mind of man, as, for example, the moon, to which is attributed the change of seasons, the progress of diseases, etc. For the chief malady of man is a restless curiosity about things which he cannot understand; and it is not so bad for him to be in error as to be curious to no purpose.
