Laudator Temporis Acti

Plato, Gorgias 458a (Socrates speaking; tr. Walter Hamilton, rev. Chris Emlyn-Jones):

And what sort of man am I? I am one of those people who are glad to have their own mistakes pointed out and glad to point out the mistakes of others, but who would just as soon have the first experience as the second; in fact I consider being refuted a greater good, inasmuch as it is better to be relieved of a very bad evil oneself than to relieve another.

ἐγὼ δὲ τίνων εἰμί; τῶν ἡδέως μὲν ἂν ἐλεγχθέντων εἴ τι μὴ ἀληθὲς λέγω, ἡδέως δ᾽ ἂν ἐλεγξάντων εἴ τίς τι μὴ ἀληθὲς λέγοι, οὐκ ἀηδέστερον μεντἂν ἐλεγχθέντων ἢ ἐλεγξάντων· μεῖζον γὰρ αὐτὸ ἀγαθὸν ἡγοῦμαι, ὅσῳπερ μεῖζον ἀγαθόν ἐστιν αὐτὸν ἀπαλλαγῆναι κακοῦ τοῦ μεγίστου ἢ ἄλλον ἀπαλλάξαι.

Paul A. Rahe, "Donald Kagan, 1932–2021," New Criterion (October 2021):

Working with Don Kagan was a delight. One could argue with the man. He was less attached to his own opinions than to the process of probing and sifting the evidence, and he was open to changing his mind.
