text: But the virtues cannot cease to be. Therefore, there are many, nay countless, living things, sojourning in this one soul. "No," is the answer, "not many, because they are all attached to the one, being parts and members of a single whole." We are then portraying for ourselves an image of the soul like that of a many-headed hydra – each separate head fighting and destroying independently. And yet there is no separate living thing to each head; it is the head of a living thing, and the hydra itself is one single living thing. No one ever believed that the Chimaera contained a living lion or a living serpent; these were merely parts of the whole Chimaera; and parts are not living things. Then how can you infer that Justice is a living thing? "Justice," people reply, "is active and helpful; that which acts and is helpful, possesses impulse; and that which possesses impulse is a living thing." True, if the impulse is its own; (but in the case of justice it is not its own;) the impulse comes from the soul. Every living thing exists as it began, until death; a man, until he dies, is a man, a horse is a horse, a dog a dog. They cannot change into anything else. Now let us grant that Justice – which is defined as "a soul in a certain attitude," is a living thing. Let us suppose this to be so. Then Bravery also is alive, being "a soul in a certain attitude." But which soul? That which was but now defined as Justice? The soul is kept within the first-named being, and cannot cross over into another; it must last out its existence in the medium where it had its origin. Besides, there cannot be one soul to two living things, much less to many living things. And if Justice, Bravery, Restraint, and all the other virtues, are living things, how will they have one soul? They must possess separate souls, or else they are not living things. Several living things cannot have one body; this is admitted by our very opponents. Now what is the "body" of justice? "The soul," they admit. And of bravery? "The soul also." And yet there cannot be one body of two living things. "The same soul, however," they answer, "assumes the guise of Justice, or Bravery, or Restraint." This would be possible if Bravery were absent when Justice was present, and if Restraint were absent when Bravery was present; as the case stands now, all the virtues exist at the same time. Hence, how can the separate virtues be living things, if you grant that there is one single soul, which cannot create more than one single living thing?
