Marcus Aurelius: “Do not then be tired of receiving what is useful by doing it to others.”

There is one light of the sun, though it is interrupted by walls, mountains, and other things infinite.

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.

But it is inconsistent with honoring reason and God to be troubled because by death a man will be deprived of the other things.

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.
