Those in whom anger or desire or any other passion, or again any insidious vice holds sway, are entirely enslaved, while all whose life is regulated … - Philo of Alexandria

τὸν μὲν οὖν τῶν Πυθαγορείων ἱερώτατον θίασον λόγος ἔχει μετὰ πολλῶν καὶ ἄλλων καλῶν καὶ τοῦτ᾿ ἀναδιδάσκειν, “ταῖς λεωφόροις μὴ βαδίζειν ὁδοῖς,” οὐχ ἵνα κρημνοβατῶμεν—οὐ γὰρ ποσὶ κάματον παρήγγελλεν—, ἀλλ᾿ αἰνιττόμενος διὰ συμβόλου τὸ μήτε λόγοις μήτ᾿ ἔργοις δημώδεσι καὶ πεπατημένοις χρῆσθαι.

Nature … has born and reared all men alike, and created them genuine brothers, not in mere name, but in very reality, though this kinship has been put to confusion by the triumph of malignant covetousness, which has wrought estrangement instead of affinity and enmity instead of friendship.

One may well wonder at the short-sightedness of those who ignore the characteristics which so clearly distinguish different things and declare that the laws of Solon and Lycurgus are all-sufficient to secure the greatest of republics, Athens and Sparta, because their sovereign authority is loyally accepted by those who enjoy that citizenship, yet deny that right reason, which is the fountain head of all other law, can impart freedom to the wise, who obey all that it prescribes or forbids.
