Let us try to persuade them [men]. But act even against their will, when the principles of justice lead that way. If however any man by using force stands in thy way, betake thyself to contentment and tranquility, and at the same time employ the hindrance towards the exercise of some other virtue; and remember that thy attempt was with a reservation, that thou didst not desire to do impossibilities. What then didst thou desire?⁠—Some such effort as this.⁠—But thou attainest thy object, if the things to which thou wast moved are accomplished.

He who loves fame considers another man’s activity to be his own good; and he who loves pleasure, his own sensations; but he who has understanding, considers his own acts to be his own good.

It is in our power to have no opinion about a thing, and not to be disturbed in our soul; for things themselves have no natural power to form our judgements.

Accustom thyself to attend carefully to what is said by another, and as much as it is possible, be in the speaker’s mind.
