In the Phaedrus we find a more detailed account of the psychology and art of love than in the Symposium. This account will be our exclusive focus. The soul, whether divine or human, Socrates claims, is like “the natural union of a team of winged horses and their charioteer” (246a6–7). But whereas in a divine soul all three elements are “good and come from good stock,” in a human soul the white horse (familiar from Republic IV as the honor-loving spirited element) is “beautiful and good, and of similar stock,” while the black one (the Republic’s appetitive element) is “the opposite and of the opposite stock,” so that “the driving in our case is necessarily difficult and troublesome” (a7-b4). When spirit together with the charioteer (the Republic’s rational element, there too identified with what is truly human rather than bestial in us (588b10–589a4)) “leads us towards what is best and is in control,” we possess moderation (sôphrosunê) (237e2–3). But when “appetite drags us irrationally towards pleasures and rules in us, its rule is called excess (hubris)” (238a1–2). Of this excess, gluttony is one species, but erotic love another (238b7-c4). This is the bad kind of love—Pandemotic in the Symposium—that Lysias rightly disparages in the speech Phaedrus admires and reads to Socrates (230e6–234c5).
In Socrates’ view, however, there is also another kind of love, namely, “the madness of a man who, on seeing beauty here on earth, and being reminded of true beauty, becomes winged, and fluttering with eagerness to fly upwards, but unable to leave the ground, looks upwards like a bird, and takes no heed of things below—and that is what causes him to be regarded as mad” (249d5-e1).
