Constitution expresses our national estimate of them by allowing us to blacken three of their eyes for the same price as one of an ordinary professional man. How many Froebels and Pestalozzis and Miss Masons and Doctoress Montessoris would you be likely to get on these terms even if they occurred much more frequently in nature than they actually do? No: I cannot be put off by the news that our system would be perfect if it were worked by angels. I do not admit it even at that, just as I do not admit that if the sky fell we should all catch larks. But I do not propose to bother about a supply of specific genius which does not exist, and which, if it did exist, could operate only by at once recognizing and establishing the rights of children. What We Do Not Teach, and Why To my mind, a glance at the subjects now taught in schools ought to convince any reasonable person that the object of the lessons is to keep children out of mischief, and not to qualify them for their part in life as responsible citizens of a free State. It is not possible to maintain freedom in any State, no matter how perfect its original constitution, unless its publicly active citizens know a good deal of constitutional history, law, and political science, with its basis of economics. If as much pains had been taken a century ago to make us all understand Ricardo's law of rent as to learn our catechisms, the face of the world would have been changed for the better. But for that very reason the greatest care is taken to keep such beneficially subversive knowledge from us, with the result that in public life we are either place-hunters, anarchists, or sheep shepherded by wolves. But it will be observed that these are highly controversial subjects. Now no controversial subject can be taught dogmatically. He who knows only the official side of a controversy knows less than nothing of its nature. The abler a schoolmaster is, the more dangerous he is to his pupils unless they have the fullest opportunity of hearing another equally able person do his utmost to shake his authority and convict him of error.
