Book VII · 73
When thou hast done a good act and another has received it, why dost thou still look for a third thing besides these, as fools do, either to have the reputation of having done a good act or to obtain a return?
When thou hast done well to another and another has fared well at thy hands, why go on like the foolish to look for a third thing besides, that is, the credit also of having done well or a return for the same?
Marcus Aurelius, Meditations VII.73. Translated by George Long (1862). The Stoic Library.
