The Injustice of Causing Pain to Oneself

Notes

1. §8.42.1ἄξιος ἐμαυτὸν λυπεῖν — The adjective ἄξιος with an infinitive means "worthy to do" or "deserving of doing". Here it means "I do not deserve to vex (or pain) myself," showing the logic that since he has never intentionally caused pain to others, he should not unfairly inflict pain upon himself either.
2. §8.42.1ἑκὼν — The adjective ἑκών (willing, of one's own accord) is used predicatively in agreement with the subject (the first-person singular masculine), functioning adverbially to mean "willingly" or "intentionally".
