Marcus Aurelius
Meditations 5.11
About what am I now employing my own soul? On every occasion I must ask myself this question, and inquire, What have I now in this part of me which they call the ruling principle? and whose soul have I now,—that of a child, or of a young man, or of a feeble woman, or of a tyrant, or of a domestic animal, or of a wild beast?
Marcus Aurelius, Meditations 5.11, translated by George Long
To what use then am I putting my soul? Never fail to ask thyself this question and to cross-examine thyself thus: What relation have I to this part of me which they call the ruling Reason? And whose Soul have I got now? The Soul of a child? Of a youth? Of a woman? Of a tyrant? Of a domestic animal? Of a wild beast?
Marcus Aurelius, Meditations 5.11, translated by C. R. Haines
