The first law that ever God gave to man was a law of pure obedience; it was a commandment naked and simple, wherein man had nothing to inquire after, or to dispute, forasmuch as to obey is the proper office of a rational soul, acknowledging a heavenly superior and benefactor. From obedience and submission spring all other virtues, as all sin does from self-opinion.

The common notions that we find in credit around us and infused into our souls by our fathers' seed, these seem to be the universal and natural ones. Whence it comes to pass that what is off the hinges of custom, people believe to be off the hinges of reason.

As for our pupils talk, let his virtue and his sense of right and wrong shine through it and have no guide but reason. Make him understand that confessing an error which he discovers in his own argument even when he alone has noticed it is an act of justice and integrity, which are the main qualities he pursues; stubbornness and rancour are vulgar qualities, visible in common souls whereas to think again, to change one's mind and to give up a bad case on the heat of the argument are rare qualities showing strength and wisdom.

Don't be afraid to say what you are not afraid to think

We have power over nothing except our will.

In true friendship, in which I am expert, I give myself to my friend more than I draw him to me. I not only like doing him good better than having him do me good, but also would rather have him do good to himself than to me; he does me most good when he does himself good.

Virtue can have naught to do with ease. . . . It craves a steep and thorny path.
