True virtue is life under the direction of reason.

If you want the present to be different from the past, study the past.

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

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

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

He alone is free who lives with free consent under the entire guidance of reason.

None are more taken in by flattery than the proud, who wish to be the first and are not.

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

If men were born free, they would, so long as they remained free, form no conception of good and evil.
