Aristotle, Physiognomics 808b
“[in this case] the soul and the body would experience things together, but they would not have the same reactions as one another. But, now, it is entirely clear that one follows another. This is especially obvious from the following. For madness seems to be a matter of the mind; doctors, however, respond to it by cleansing the body with medicines and also by telling them to pursue certain habits in life which may relieve the mind of madness.
So, the form of the body is relieved by treatments to the body at the very same time that the soul is freed from madness. Since they are both relieved together, it is clear that their reactions are in synchrony. It is also clear from this that the forms special to the body are similar to the capabilities of the mind, with the result that all similarities in living things are clear signs of some kind of sameness.”
ἡ ψυχή τε καὶ τὸ σῶμα συμπαθῆ, οὐ μέντοι συνδιατελοῦντα ἀλλήλοις. νῦν δὲ καταφανὲς ὅτι ἑκάτερον ἑκατέρῳ ἕπεται. μάλιστα μέντοι ἐκ τοῦδε δῆλον γένοιτο. μανία γὰρ δοκεῖ εἶναι περὶ ψυχήν, καὶ οἱ ἰατροὶ φαρμάκοις καθαίροντες τὸ σῶμα καὶ διαίταις τισὶ πρὸς αὐτοῖς χρησάμενοι ἀπαλλάττουσι τὴν ψυχὴν τῆς μανίας. ταῖς δὴ τοῦ σώματος θεραπείαις καὶ ἅμα ἥ τε τοῦ σώματος μορφὴ λέλυται καὶ ἡ ψυχὴ μανίας ἀπήλλακται. ἐπειδὴ οὖν ἅμα ἀμφότερα λύονται, δῆλον ὅτι συνδιατελοῦσιν ἀλλήλοις. συμφανὲς δὲ καὶ ὅτι ταῖς δυνάμεσι τῆς ψυχῆς ὅμοιαι αἱ μορφαὶ τοῖς σώμασιν ἐπιγίνονται, ὥστ᾿ ἐστὶν ἅπαντα ὅμοια ἐν τοῖς ζῴοις τοῦ αὐτοῦ τινὸς δηλωτικά.
Epictetus, Fr. 26
“Epictetus used to say, ‘you’re a tiny soul lugging around a corpse’.”
Ψυχάριον εἶ βαστάζον νεκρόν, ὡς Ἐπίκτητος ἔλεγεν.
