For what is meant by saying that a government ought to educate the people? Why should they be educated? What is the education for? Clearly, to fit the people for social life - to make them good citizens. And who is to say what are good citizens? The government: there is no other judge. And who is to say how these good citizens may be made? The government: there is no other judge. Hence the proposition is convertible into this - a government ought to mold children into good citizens, using its own discretion in settling what a good citizen is and how the child may be molded into one.
