A wise man gets more use from his enemies than a fool from his friends.

Without courage, wisdom bears no fruit.

Folly consists not in committing Folly, but in being incapable of concealing it. All men make mistakes, but the wise conceal the blunders they have made, while fools make them public. Reputation depends more on what is hidden than on what is seen. If you can’t be good, be careful.

We have eyelids but not earlids, for the ears are the portals of learning, and Nature wanted to keep them wide open.

Do not be held a cheat, even though it is impossible to live today without being one. Let your greatest cunning lie in covering up what looks like cunning.

The wise are always impatient, for he that increases knowledge increases impatience of folly.

Be first the master of yourself

Knowledge without wisdom is double folly.

Some would be sages if they did not believe they were so already.
