The things we know best are the things we haven't been taught.

Reason deceives us more often than does nature.

Reason and emotion counsel and supplement each other. Whoever heeds only the one, and puts aside the other, recklessly deprives himself of a portion of the aid granted us for the regulation of our conduct.

Few people are modest enough to be estimated at their true worth.

We ought never to be afraid to repeat an ancient truth, when we feel that we can make it more striking by a neater turn, or bring it alongside of another truth, which may make it clearer, and thereby accumulate evidence. It belongs to the inventive faculty to see clearly the relative state of things, and to be able to place them in connection; but the discoveries of ages gone by belong less to their first authors than to those who make them practically useful to the world.

It is unjust to exact that men shall do out of deference to our advice what they have no desire to do for themselves.

It is a great sign of mediocrity to praise always moderately.
