Laudator Temporis Acti

Polybius 1.81.5-7 (tr. W.R. Paton):

[5] No one looking at this would have any hesitation in saying that not only do men's bodies and certain of the ulcers and tumours afflicting them become so to speak savage and brutalized and quite incurable, but that this is true in a much higher degree of their souls. [6] In the case of ulcers, if we treat them, they are sometimes inflamed by the treatment itself and spread more rapidly, while again if we neglect them they continue, in virtue of their own nature, to eat into the flesh and never rest until they have utterly destroyed the tissues beneath. [7] Similarly such malignant lividities and putrid ulcers often grow in the human soul, that no beast becomes at the end more wicked or cruel than man.

[5] διόπερ εἰς ταῦτα βλέπων οὐκ ἄν τις εἰπεῖν ὀκνήσειεν ὡς οὐ μόνον τὰ σώματα τῶν ἀνθρώπων καί τινα τῶν ἐν αὐτοῖς γεννωμένων ἑλκῶν καὶ φυμάτων ἀποθηριοῦσθαι συμβαίνει καὶ τελέως ἀβοήθητα γίνεσθαι, πολὺ δὲ μάλιστα τὰς ψυχάς. [6] ἐπί τε γὰρ τῶν ἑλκῶν, ἐὰν μὲν θεραπείαν τοῖς τοιούτοις προσάγῃ τις, ὑπ' αὐτῆς ἐνίοτε ταύτης ἐρεθιζόμενα θᾶττον ποιεῖται τὴν νομήν· ἐὰν δὲ πάλιν ἀφῇ, κατὰ τὴν ἐξ αὑτῶν φύσιν φθείροντα τὸ συνεχὲς οὐκ ἴσχει παῦλαν, ἕως ἂν ἀφανίσῃ τὸ ὑποκείμενον· [7] ταῖς τε ψυχαῖς παραπλησίως τοιαῦται πολλάκις ἐπιφύονται μελανίαι καὶ σηπεδόνες ὥστε μηδὲν ἀσεβέστερον ἀνθρώπου μηδ' ὠμότερον ἀποτελεῖσθαι τῶν ζῴων.
