An umpire’s decision; the degree to which one may transgress the spirit of a regulation without being trapped by the letter: on such questions as these, children are born casuists, and their natural propensity only needs to be developed and trained–and especially, brought into an intelligible relationship with the events in the grown-up world. The newspapers are full of good material for such exercises: legal decisions, on the one hand, in cases where the cause at issue is not too abstruse; on the other, fallacious reasoning and muddleheaded arguments, with which the correspondence columns of certain papers one could name are abundantly stocked.

Wherever the matter for Dialectic is found, it is, of course, highly important that attention should be focused upon the beauty and economy of a fine demonstration or a well-turned argument, lest veneration should wholly die. Criticism must not be merely destructive; though at the same time both teacher and pupils must be ready to detect fallacy, slipshod reasoning, ambiguity, irrelevance, and redundancy, and to pounce upon them like rats. This is the moment when precis-writing may be usefully undertaken; together with such exercises as the writing of an essay, and the reduction of it, when written, by 25 or 50 percent.

It will, doubtless, be objected that to encourage young persons at the Pert age to browbeat, correct, and argue with their elders will render them perfectly intolerable. My answer is that children of that age are intolerable anyhow; and that their natural argumentativeness may just as well be canalized to good purpose as allowed to run away into the sands. It may, indeed, be rather less obtrusive at home if it is disciplined in school; and anyhow, elders who have abandoned the wholesome principle that children should be seen and not heard have no one to blame but themselves.
