And the shoemaker was not allowed by us to be a husbandman, or a weaver, or a builder—in order that we might have our shoes well made; but to him and to every other worker was assigned one work for which he was by nature fitted, and at that he was to continue working all his life long and at no other; he was not to let opportunities slip, and then he would become a good workman. Now nothing can be more important than that the work of a soldier should be well done. But is war an art so easily acquired that a man may be a warrior who is also a husbandman, or shoemaker, or other artisan; although no one in the world would be a good dice or draught player who merely took up the game as a recreation, and had not from his earliest years devoted himself to this and nothing else? No tools will make a man a skilled workman, or master of defence, nor be of any use to him who has not learned how to handle them, and has never bestowed any attention upon them. How then will he who takes up a shield or other implement of war become a good fighter all in a day, whether with heavy-armed or any other kind of troops? Yes, he said, the tools which would teach men their own use would be beyond price. And the higher the duties of the guardian, I said, the more time, and skill, and art, and application will be needed by him? No doubt, he replied. Will he not also require natural aptitude for his calling? Certainly. Then it will be our duty to select, if we can, natures which are fitted for the task of guarding the city? It will. And the selection will be no easy matter, I said; but we must be brave and do our best. We must. Is not the noble youth very like a well-bred dog in respect of guarding and watching? What do you mean? I mean that both of them ought to be quick to see, and swift to overtake the enemy when they see him; and strong too if, when they have caught him, they have to fight with him. All these qualities, he replied, will certainly be required by them. Well, and your guardian must be brave if he is to fight well? Certainly. And is he likely to be brave who has no spirit, whether horse or dog or any other animal? Have you never observed how invincible and unconquerable is spirit and how the presence of it makes the soul of any creature to be absolutely fearless and indomitable? I have. Then now we have a clear notion of the bodily qualities which are required in the guardian. True. And also of the mental ones; his soul is to be full of spirit? Yes. But are not these spirited natures apt to be savage with one another, and with everybody else? A difficulty by no means easy to overcome, he replied. Whereas, I said, they ought to be dangerous to their enemies, and gentle to their friends; if not, they will destroy themselves without waiting for their enemies to destroy them. True, he said.
