opposites; and this is what Heracleitus meant, when he spoke of a harmony of opposites: but in strictness he should rather have spoken of a harmony which succeeds opposites, for an agreement of disagreements there cannot be. Music too is concerned with the principles of love in their application to harmony and rhythm. In the abstract, all is simple, and we are not troubled with the twofold love; but when they are applied in education with their accompaniments of song and metre, then the discord begins. Then the old tale has to be repeated of fair Urania and the coarse Polyhymnia, who must be indulged sparingly, just as in my own art of medicine care must be taken that the taste of the epicure be gratified without inflicting upon him the attendant penalty of disease.

For divination is the peacemaker of gods and men, and works by a knowledge of the tendencies of merely human loves to piety and impiety. Such is the power of love; and that love which is just and temperate has the greatest power, and is the source of all our happiness and friendship with the gods and with one another. I dare say that I have omitted to mention many things which you, Aristophanes, may supply, as I perceive that you are cured of the hiccough.
Aristophanes is the next speaker:—
He professes to open a new vein of discourse, in which he begins by treating of the origin of human nature. The sexes were originally three, men, women, and the union of the two; and they were made round—having four hands, four feet, two faces on a round neck, and the rest to correspond. Terrible was their strength and swiftness; and they were
