An ounce of prudence is worth a pound of cleverness.

A synonym is a word you use when you can't spell the other one.

Do not be inaccessible. None is so perfect that he does not need at times the advice of others. He is an incorrigible ass who will never listen to any one. Even the most surpassing intellect should find a place for friendly counsel. Sovereignty itself must learn to lean.

The highest should have the door open for friendship; it may prove the gate of help. A friend must be free to advise, and even to upbraid, without feeling embarrassed.

Even knowledge has to be in the fashion, and where it is not, it is wise to affect ignorance.
