True virtue is life under the direction of reason.

The greater emotion with which we conceive a loved object to be affected toward us, the greater will be our complacency.

The endeavor to understand is the first and only basis of virtue.

Whatsoever is, is in God.

Whatsoever is contrary to nature is contrary to reason, and whatsoever is contrary to reason is absurd.

The greatest pride, or the greatest despondency, is the greatest ignorance of one's self.

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