Amor fati. Marcus Aurelius 5.18

Marcus believes that we are capable of bearing all things that happen to us, even the worst disasters. He exhorts himself to find the power to press forward when life is most difficult, refusing to surrender to despair even as we lose all we hold dear. History shows us fools and people-pleasers capable of great endurance, great suffering that they do not turn to ill effect upon others. If they can do it, then the wise man must do no less. Else what use were all his wisdom?

Οὐδὲν οὐδενὶ συμβαίνει ὃ οὐχὶ ἐκεῖνο πέφυκε φέρειν. ἄλλῳ τὰ αὐτὰ συμβαίνει καὶ ἤτοι ἀγνοῶν ὅτι συμβέβηκεν, ἢ ἐπιδεικνύμενος μεγαλοφροσύνην, εὐσταθεῖ καὶ ἀκάκωτος μένει. δεινὸν οὖν ἄγνοιαν καὶ ἀρέσκειαν ἰσχυροτέρας εἶναι φρονήσεως.

Nothing happens to us that nature has not prepared us to bear. If you doubt this, watch how another endures what overwhelms you: see how he ignores that it ever happened, or how he remains steadfast and unbroken in spite of it, showing the greatness of his mind. It would be a terrible thing if ignorance and complaisance were mightier here than wisdom.
