[417a]
such as συμφέροντα (advantageous), λυσιτελοῦντα (profitable), ὠφέλιμα (useful), κερδαλέα (gainful), and their opposites.Socrates
You might by this time be able to find the meaning of συμφέροντα by yourself in the light of the previous explanations, for it appears to be own brother to ἐπιστήμη. It means nothing else but the motion (φορά) of the soul in company with the world, and naturally things which are done by such a power are called συμφέροντα and σύμφορα because they are carried round with (συμπεριφέρεσθαι) the world. But κερδαλέον is from κέρδος (gain).
