In plain words, ours
Some things are up to us and some are not. Our opinions, urges, wants and dislikes are. Our body, property, reputation and position are not.
OF things some are in our power, and others are not. In our power are opinion (ὑπόληψις), movement towards a thing (ὁρμή), desire, aversion (ἔκκλισις, turning from a thing); and in a word, whatever are our own acts: not in our power are the body, property, reputation, offices (magisterial power), and in a word, whatever are not our own acts.
