Failure to read what is happening in another's soul is not easily seen as a cause of unhappiness: but those who fail to attend the motions of their own soul are necessarily unhappy.

Search men's governing principles, and consider the wise, what they shun and what they cleave to.

Why do you hunger for length of days? The point of life is to follow reason and the divine spirit and to accept whatever nature sends you.
