To study philosophy is nothing but to prepare one’s self to die.

There is also a tradition about Socrates. He liked walking, it is recorded, until a late hour of the evening, and when someone asked him why he did this he said he was trying to work up an appetite for his dinner.

Sed nescio quo modo nihil tam absurde dici potest quod non dicatur ab aliquo philosphorum. (There is nothing so absurd but some philosopher has said it.)

No power on earth, if it labours beneath the burden of fear, can possibly be strong enough to survive.

Since it's clear then that what sets itself in motion is eternal, who could fail to attribute such a nature to the soul. Anything set in motion by external impetus is inanimate; what is animate moves by its own interior impulse. This is the nature and power of soul. And because it is the one thing out of all that sets itself in motion, then surely it was never born and will last forever.

O philosophy, life's guide! O searcher-out of virtue and expeller of vices! What could we and every age of men have been without thee? Thou hast produced cities; thou hast called men scattered about into the social enjoyment of life. [Lat., O vitae philosophia dux! O virtutis indagatrix, expultrixque vitiorum! Quid non modo nos, sed omnino vita hominum sine et esse potuisset? Tu urbes peperisti; tu dissipatos homines in societatum vitae convocasti.]
