There must be a co-education of the different social classes as well as of the two sexes. I might have founded a school giving lessons gratuitously; but a school for poor children only would not be a rational school, since, if they were not taught submission and credulity as in the old type of school, they would have been strongly disposed to rebel, and would instinctively cherish sentiments of hatred.
There is no escape from the dilemma. There is no middle term in the school for the disinherited class alone; you have either a systematic insistence, by means of false teaching, on error and ignorance, or hatred of those who domineer and exploit.
It needs very little reflection to see that a school for rich children only cannot be a rational school. From the very nature of things it will tend to insist on the maintenance of privilege and the securing of their advantages. The only sound and enlightened form of school is that which co-educates the poor and the rich, which brings the one class into touch with the other in the innocent equality of childhood, by means of the systematic equality of the rational school.
