I venture to say quite plainly: the oppressed and the exploited have a right to rebel, because they have to reclaim their rights until they enjoy their full share in the common patrimony. The Modern School, however, has to deal with children, whom it prepares by instruction for the state of manhood, and it must not anticipate the cravings and hatreds, the adhesions and rebellions, which may be fitting sentiments in the adult. In other words, it must not seek to gather fruit until it has been produced by cultivation, nor must it attempt to implant a sense of responsibility until it has equipped the conscience with the fundamental conditions of such responsibility. Let it teach the children to be men; when they are men, they may declare themselves rebels against injustice.
