Diogenes Laërtius on the Philosopher in Exile

A Latin copy of the Sixth Book of Diogenes Laërtius, from which the quote is taken, published in Venice by Nicholas Jenson in 1476

And it happened that someone came to speak with reproach about the fact that he had been exiled. But Diogenes replied abruptly, saying: “No, you dense fellow, that is how I came to be a philosopher.” And when someone reminded him that it was his own people of Sinope who had sentenced him to exile, he responded: “As I sentenced them, to tedious domesticity.”
