Creatures of a day. Marcus Aurelius 4.35

A recurring Stoic theme is the mortality of everything about us. What is truly excellent, they might say, about our condition: we can always release anything we hold. Ideally, we release all holds before they become evil, to us or to others with whom our little moment of life is shared. Our mistakes need not be terrible or irrevocable, as we ourselves are not eternal, and so not liable to the divine sins of Olympus.

Πᾶν ἐφήμερον, καὶ τὸ μνημονεῦον καὶ τὸ μνημονευόμενον.

Everything lives for but a day, both the mind that marks and the world of things illustrated in its memories.
