You speak an infinite deal of nothing.

I look only to the good qualities of men. Not being faultless myself, I won't presume to probe into the faults of others.

Look not to the faults of others, nor to their omissions and commissions. But rather look to your own acts, to what you have done and left undone.

Avoid him who talks sweetly before you but tries to ruin you behind your back, for he is like a pitcher full of poison with milk on top.

Good behavior wins even an enemy.

Do not put your trust in a bad companion nor even trust an ordinary friend, for if he should get angry with you, he may bring all your secrets to light.
