Marcus Aurelius: “As thou thyself art a component part of a social system, so let every act of thine be a component part of social life.”

There is one intelligent soul, though it seems to be divided.

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!
