The McGuffey Readers had staying qualities. Teachers often became so familiar with their contents that they needed no book in their hands to correct the work, but to each child the contents of the book were new and fresh. It is the fashion of the present day to exalt the new at the expense of the old. But the child of today is very much such as Socrates and Plato studied in Greece. The development of the human mind may be more generally understood than it was then; but it may be doubted whether the mass of teachers are today wiser in the results of child-study than were the philosophers of ancient days. Child nature remains the same. At a given stage in his upward progress, he is interested in much the same things. He is led to think for himself in much the same way, and the whole end and aim of education is to lead toward self activity. The readers that deal simply with facts--information readers--may lodge in the minds of children some scraps of encyclopedic information which may in future life become useful. But the readers that rouse the moral sentiments, that touch the imagination, that elevate and establish character by selections chosen from the wisest writers in English in all the centuries that have passed since our language assumed a comparatively fixed literary form, have a much more valuable function to perform. Character is more valuable than knowledge and a taste for pure and ennobling literature is a safeguard for the young that cannot be safely ignored. The success of the McGuffey Readers was due primarily to their adaptation to the general demand of the schools and secondarily to the energy and skill of their publishers. [Moral Teaching] The books in their first form were strongly religious in their teaching without being denominational. If a selection taught a moral lesson this was stated in formal words at the close. The pill was not sugared. Thus at the close of a lesson narrating the results of disobedience, the three little girls assembled and "they were talking how happy it made them to keep the Fifth Commandment." There was in the books much direct teaching of moral principles, with "thou shalt" and "thou shalt not." In the later revisions this gradually disappeared. The moral teaching was less direct but more effective. The pupil was left to make his own deduction and the formal "haec fabula docet" was omitted. The author and the publishers were fully justified in their firm belief that the American people are a moral people and that they have a strong desire that their children be taught to become brave, patriotic, honest, self-reliant, temperate, and virtuous citizens. In some of these books the retail price is printed. In 1844 the retail price of the First Reader was twelve and a half cents. It contained 108 pages. In the same year, the Second Reader of 216 pages was priced at 25 cents. The Fourth Reader cost 75 cents, and contained 336 pages.
