Therefore, he concludes, let the spread of enlightenment be free and spontaneous. “If supply and demand are allowed free play in the intellectual sphere as in the economic sphere, ... education must conduce to social stability as well as to the other benefits. For if those of the lower ranks are left to get culture for their children as best they may, just as they are left to get food and clothing for them, it must follow that the children of the superior will be advantaged: the thrifty parents, the energetic, and those with a high sense of responsibility will buy education for their children to a greater extent than will the improvident and the idle. And if character is inherited, then the average result must be that the children of the superior will prosper and increase more than the children of the inferior. There will be a multiplication of the fittest instead of a multiplication of the unfittest” (10: pp. 92-93). Spencer’s treatise on “Education: Intellectual, Moral, and Physical,” in which most of his pedagogical views are given, though a mere collection of occasional magazine articles, is nevertheless a work into which he put his heart and soul. When it appeared in 1860, in book form, it carried his fame for the first time into the wide region of the world; it has been translated into thirteen languages; in England and America it has been used as a text-book, forming until recently an important basis of popular pedagogic ideas. Probably no educational treatise written in English has exerted a wider influence than Spencer’s, and in spite of its obvious one-sidedness, it is certainly one of the greatest works which has appeared in the pedagogic world on Anglo-Saxon soil.
