What is the difference? he said.
That I will endeavour to explain, I replied. To keep watchdogs, who, from want of discipline or hunger, or some evil habit, or 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 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.
