Not in the present generation, he replied; there is no way of accomplishing this; but their sons may be made to believe in the tale, and their sons’ sons, and posterity after them. I see the difficulty, I replied; yet the fostering of such a belief will make them care more for the city and for one another. Enough, however, of the fiction, which may now fly abroad upon the wings of rumour, while we arm our earth-born heroes, and lead them forth under the command of their rulers. Let them look round and select a spot whence they can best suppress insurrection, if any prove refractory within, and also defend themselves against enemies, who like wolves may come down on the fold from without; there let them encamp, and when they have encamped, let them sacrifice to the proper Gods and prepare their dwellings. Just so, he said. And their dwellings must be such as will shield them against the cold of winter and the heat of summer. I suppose that you mean houses, he replied. Yes, I said; but they must be the houses of soldiers, and not of shop-keepers. What is the difference? he said. That I will endeavour to explain, I replied. To keep watch-dogs, who, from want of discipline or hunger, or some evil habit or other, would turn upon the sheep and worry them, and behave not like dogs but wolves, would be a foul and monstrous thing in a shepherd? Truly monstrous, he said. And therefore every care must be taken that our auxiliaries, being stronger than our citizens, may not grow to be too much for them and become savage tyrants instead of friends and allies? Yes, great care should be taken. And would not a really good education furnish the best safeguard? But they are well-educated already, he replied. I cannot be so confident, my dear Glaucon, I said; I am much more certain that they ought to be, and that true education, whatever that may be, will have the greatest tendency to civilize and humanize them in their relations to one another, and to those who are under their protection. Very true, he replied. And not only their education, but their habitations, and all that belongs to them, should be such as will neither impair their virtue as guardians, nor tempt them to prey upon the other citizens. Any man of sense must acknowledge that. He must.
