Marcus Aurelius: “And all our assent is changeable; for where is the man who never changes?”

But intellect in a peculiar manner tends to that which is of the same kin, and combines with it, and the feeling for communion is not interrupted.

The safety of life is this, to examine everything all through, what it is itself, that is its material, what the formal part; with all thy soul to do justice and to say the truth.

But if it is easy to set little value on all these things, turn to that which remains, which is to follow reason and God.

And how small a part of the whole substance; and how small a part of the universal soul; and on what a small clod of the whole earth thou creepest!
