Whatever one of us blames in another, each one will find in his own heart.

It is another's fault if he be ungrateful, but it is mine if I do not give. To find one thankful man, I will oblige a great many that are not so.

Every guilty person is his own hangman.

Most powerful is he who has himself in his own power.

No evil propensity of the human heart is so powerful that it may not be subdued by discipline.

Consult your friend on all things, especially on those which respect yourself. His counsel may then be useful where your own self-love might impair your judgment.
