Every fool stands convinced; and everyone convinced is a fool. The faultier a person's judgement the firmer their convictions.
He that has satisfied his thirst turns his back on the well.
Trust your heart, especially when it is a strong one.
All victories breed, and that over your superior is foolish or fatal.
Wisdom and courage make mutual contributions to greatness.
The greatest fool is he who thinks he is not one and all others are.
