Plato, Phaedrus

[254a] prickings of yearning, the horse that is obedient the charioteer, constrained then as always by modesty, controls himself and does not leap upon the beloved; but the other no longer heeds the pricks or the whip of the charioteer, but springs wildly forward, causing all possible trouble to his mate and to the charioteer, and forcing them to approach the beloved and propose the joys of love. And they at first pull back indignantly and [254b] will not be forced to do terrible and unlawful deeds; but finally, as the trouble has no end, they go forward with him, yielding and agreeing to do his bidding. And they come to the beloved and behold his radiant face. And as the charioteer looks upon him, his memory is borne back to the true nature of beauty, and he sees it standing with modesty upon a pedestal of chastity, and when he sees this he is afraid and falls backward in reverence, and in falling he is forced to pull the reins [254c] so violently backward as to bring both horses upon their haunches, the one quite willing, since he does not oppose him, but the unruly beast very unwilling. And as they go away, one horse in his shame and wonder wets all the soul with sweat, but the other, as soon as he is recovered from the pain of the bit and the fail, before he has fairly taken breath, breaks forth into angry reproaches, bitterly reviling his mate and [254d] the charioteer for their cowardice and lack of manhood in deserting their post and breaking their agreement; and again, in spite of their unwillingness, he urges them forward and hardly yields to their prayer that he postpone the matter to another time. Then when the time comes which they have agreed upon, they pretend that they have forgotten it, but he reminds them; struggling, and neighing, and pulling he forces them again with the same purpose to approach the beloved one, and when they are near him, he lowers his head, raises his tail, takes the bit in his teeth, [254e] and pulls shamelessly. The effect upon the charioteer is the same as before, but more pronounced; he falls back like a racer from the starting-rope, pulls the bit backward even more violently than before from the teeth of the unruly horse, covers his scurrilous tongue and jaws with blood, and forces his legs and haunches to the ground, causing him much pain. Now when the bad horse has gone through the same experience many times and has ceased from his unruliness, he is humbled and follows henceforth the wisdom of the charioteer, and when he sees the beautiful one, he is overwhelmed with fear; and so from that time on the soul of the lover follows the beloved in reverence and awe.
