From Apollonius I learned freedom of will and undeviating steadiness of purpose; and to look to nothing else, not even for a moment, except to reason; and to be always the same, in sharp pains, on the occasion of the loss of a child, and in long illness.

No one loses any other life than the one he now lives, nor does one live any other life than that which he will lose.

Body. Soul. Mind. Sensations: the body. Desires: the soul. Reasoning: the mind.

Vex not thy spirit at the course of things, they heed not thy vexations

Bear in mind that the measure of a man is the worth of the things he cares about.

Frequently consider the connection of all things in the universe.

We are born for cooperation, as are the feet, the hands, the eyelids, and the upper and lower jaws.
