Maxims are to the intellect what laws are to actions; they do not enlighten, but they guide and direct, and, although themselves blind, are protective.
I am of opinion that there is no proverb which is not true, because they are all sentences drawn from experience itself, the mother of all the sciences.
A maxim is a conclusion upon observation of matters of fact, and is merely speculative; a principle carries knowledge within itself, and is prospective.
