“a human being is a rational animal. Hence his good is complete if he fulfills that for which he is born. But what is it that this rationality requires of him? The easiest thing of all: to live in accordance with his own nature. It is our shared insanity that makes this difficult: we push one another into faults. And how can we be recalled to health, when all people drive us forward and no one holds us back?”
– Seneca, Letters 41.8
