"Remember that nothing is to be had for nothing."

Discourses 4.2.2 [Carter Trans.]

"Only the educated are free."

Discourses 2.1.22 [Matheson Trans.]

"Why are you concerned about things that are not your own?"

Discourses 2.13.18 [Oldfather Trans.]

"Some things are under our control while others are not. Under our control are choice and all the acts of our choice; but not under our control are the body, the parts of the body, possessions, parents, brothers, children, country--in a word, all with which we associate."

Discourses 1.22.9,10 [Oldfather Trans.]

Seek and you shall find, for nature supplies you with means to find the truth. If, with these means and no more to guide you, you cannot find the answer for yourself, then listen to those who have already made the search.

Discourses 4.1.51,52 [Matheson Trans.]

Although life itself is a matter of indifference, the use you make of it is not.

Discourses 2.6.1 [Oldfather Trans.]

When you do a thing because you have determined that it ought to be done, never avoid being seen doing it, even if the opinion of the multitude is going to condemn you. For if your action is wrong, then avoid doing it altogether, but if it is right, why do you fear those who will rebuke you wrongly?
