Of all the things that are beyond my power, I value nothing more highly than to be allowed the honor of entering into bonds of friendship with people who sincerely love truth. For, of things beyond our power, I believe there is nothing in the world which we can love with tranquility except such men.

The highest activity a human being can attain is learning for understanding, because to understand is to be free.

The less the mind understands and the more things it perceives, the greater its power of feigning is; and the more things it understands, the more that power is diminished.

Laws which can be broken without any wrong to one's neighbor are a laughing-stock; and such laws, instead of restraining the appetites and lusts of mankind, serve rather to heighten them. Nitimur in vetitum semper, cupimusque negata [we always resist prohibitions, and yearn for what is denied us].

God is the indwelling and not the transient cause of all things.

Schisms do not originate in a love of truth, which is a source of courtesy and gentleness, but rather in an inordinate desire for supremacy.

Whatsoever is, is in God, and without God nothing can be, or be conceived.
