Some things are up to us and others are not

Donald's Commentary on The Handbook of Epictetus #1

Some things are under our control, while others are not under our control. Under our control are conception, choice, desire, aversion, and, in a word, everything that is our own doing; not under our control are our body, our property, reputation, office, and, in a word, everything that is not our own doing. Furthermore, the things under our control are by nature free, unhindered, and unimpeded; while the things not under our control are weak, servile, subject to hindrance, and not our own.

Remember, therefore, that if what is naturally slavish you think to be free, and what is not your own to be your own, you will be hampered, will grieve, will be in turmoil, and will blame both gods and men; while if you think only what is your own to be your own, and what is not your own to be, as it really is, not your own, then no one will ever be able to exert compulsion upon you, no one will hinder you, you will blame no one, will find fault with no one, will do absolutely nothing against your will, you will have no personal enemy, no one will harm you, for neither is there any harm that can touch you. — Enchiridion, 1

Comment

Some things are up to us whereas others are not. Arrian of Nicomedia, who compiled the Handbook and Discourses from notes made during Epictetus' lectures, put this sentence first because it's so fundamental to everything else that follows.
