Observe constantly that all things take place by change, and accustom thyself to consider that the nature of the Universe loves nothing so much as to change the things which are and to make new things like them. For everything that exists is in a manner the seed of that which will be. But thou art thinking only of seeds which are cast into the earth or into a womb: but this is a very vulgar notion.

Thou wilt soon die, and thou art not yet simple, not free from perturbations, nor without suspicion of being hurt by external things, nor kindly disposed towards all; nor dost thou yet place wisdom only in acting justly.

Examine men’s ruling principles, even those of the wise, what kind of things they avoid, and what kind they pursue.
