It is just the same with all the other sciences. There is nothing occult or mysterious about them. No just cause or impediment exists why we should insist on being ignorant of the orbits of the planets because we cannot ourselves make the calculations for determining them; no reason why we should insist on being ignorant of the classification of plants and animals because we don't feel able ourselves to embark on anatomical researches which would justify us in coming to original conclusions about them. I know the mass of scientific opinion has always gone the other way; but then scientific opinion means only the opinion of men of science, who are themselves specialists, and who think most of the education needed to make men specialists, not of the education needed to fit them for the general exigencies and emergencies of life. We don't want authorities on the Cucurbitaceae, but well-informed citizens. Professor Huxley is not our best guide in these matters, but Mr. Herbert Spencer, who long ago, in his book on Education, sketched out a radical programme of instruction in that knowledge which is of most worth, such as no country, no college, no school in Europe has ever yet been bold enough to put into practice. What common sense really demands, then, is education in the main results of all the sciences--a knowledge of what is known, not necessarily a knowledge of each successive step by which men came to know it. At present, of course, in all our schools in England there is no systematic teaching of knowledge at all; what replaces it is a teaching of the facts of language, and for the most part of useless facts, or even of exploded fictions. Our public schools, especially (by which phrase we never mean real public schools like the board schools at all, but merely schools for the upper and the middle classes) are in their existing stage primarily great gymnasiums--very good things, too, in their way, against which I have not a word of blame; and, secondarily, places for imparting a sham and imperfect knowledge of some few philological facts about two extinct languages. Pupils get a smattering of Homer and Cicero. That is literally all the equipment for life that the cleverest and most industrious boys can ever take away from them. The sillier or idler don't take away even that. As to the "mental training" argument, so often trotted out, it is childish enough not to be worth answering. Which is most practically useful to us in life--knowledge of Latin grammar or knowledge of ourselves and the world we live in, physical, social, moral? That is the question.
