Look to nothing, not even for a moment except to reason.

Do not consider anything for your interest which makes you break your word, quit your modesty or inclines you to any practice which will not bear the light or look the world in the face.

Continuously thou wilt look at human things as smoke and nothing at all; especially if thou reflectest at the same time, that what has once changed will never exist again in the infinite duration of time. But thou, in what a brief space of time is thy existence? And why art thou not content to pass through this short time in an orderly way?

Look at everything that exists, and observe that it is already in dissolution and in change, and as it were putrefaction or dispersion, or that everything is so constituted by nature as to die.
