Meditations (c. 121–180 AD), Book X
Context: When thou art offended at any man's fault, forthwith turn to thyself and reflect in what manner thou doest error thyself... For by attending to this thou wilt quickly forget thy anger, if this consideration is also added, that the man is compelled; for what else could he do? or, if thou art able, take away from him the compulsion.
Tabulae Votivae (Votive Tablets) (1796), "The Key"; tr. Edgar Alfred Bowring, The Poems of Schiller, Complete (1851)
Variant translation:[citation needed]
If you want to know yourself,
Just look how others do it;
If you want to understand others,
Look into your own heart

Context: Even as bad actors cannot sing alone, but only in chorus: so some cannot walk alone. Man, if thou art aught, strive to walk alone and hold converse with yourself, instead of skulking in the chorus! at length think; look around thee; bestir thyself, that thou mayest know who thou art! (103).
“Man know thyself; then thou shalt know the Universe and God.”
