"Apollonius … explained his motive in practicing wisdom, declaring that the sole use he had made of it was to gain knowledge of the gods and an understanding of human affairs, for that the difficulty of knowing another man exceeded that of knowing oneself."

“I, whenever I see thee, thirst, and holding the cup, apply it to my lips more for thy sake than for drinking.”

“What induces you, he said, "Apollonius, to dress yourself differently from everybody else, and to wear this peculiar and singular garb?" "Because," said Apollonius, "the earth which feeds me also clothes me, and I do not like to bother the poor animals.”

“One day the king was going to hunt the animals in the parks in which the barbarians keep lions and bears and leopards, and he asked Apollonius to accompany him on the chase, but the latter replied: "You have forgotten, O king, that I never attend you, even when you are sacrificing. And moreover, it is no pleasure to me to attack animals that have been ill-treated and enslaved in violation of their nature.”
