All happiness or unhappiness solely depends upon the quality of the object to which we are attached by love.

He, who knows how to distinguish between true and false, must have an adequate idea of true and false.

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.

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.

In proportion as we endeavor to live according to the guidance of reason, shall we strive as much as possible to depend less on hope, to liberate ourselves from fear, to rule fortune, and to direct our actions by the sure counsels of reason.

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

Ambition is the immoderate desire for honor.
