Marcus Aurelius
Meditations 1.6
From Diognetus, not to busy myself about trifling things, and not to give credit to what was said by miracle-workers and jugglers about incantations and the driving away of daemons and such things; and not to breed quails [for fighting], nor to give myself up passionately to such things; and to endure freedom of speech; and to have become intimate with philosophy; and to have been a hearer, first of Bacchius, then of Tandasis and Marcianus; and to have written dialogues in my youth; and to have desired a plank bed and skin, and whatever else of the kind belongs to the Grecian discipline.
Marcus Aurelius, Meditations 1.6, translated by George Long
From Diognetus, not to be taken up with trifles; and not to give credence to the statements of miracle-mongers and wizards about incantations and the exorcizing of demons, and such-like marvels; and not to keep quails, nor to be excited about such things: not to resent plain speaking; and to become familiar with philosophy and be a heaver first of Baccheius, then of Tandasis and Marcianus; and to write dialogues as a boy; and to set my heart on a pallet-bed and a pelt and whatever else tallied with the Greek regimen.
