Socrates
Socrates. The name ἵμερος (longing) was given to the stream (ῥοῦς) which most draws the soul; for because it flows with a rush (ἱέμενος) and with a desire for things and thus draws the soul on through the impulse of its flowing, all this power gives it the name of ἵμερος. And the word πόθος (yearning) signifies that it pertains not to that which is present, but to that which is elsewhere (ἄλλοθί που) or absent, and therefore the same feeling which is called ἵμερος when its object is present, is called πόθος when it is absent. And ἔρως (love) is so called because it flows in (ἐσρεῖ) from without, and this flowing is not inherent in him who has it, but is introduced through the eyes; for this reason it was in ancient times called ἔσρος, from ἐσρεῖν—for we used to employ omicron instead of omega—but now it is called ἔρως through the change of omicron to omega. Well, what more is there that you want to examine?
