That any rational and accountable being should ever have been found to oppose the progress of truth, is truly humiliating; yet every page of history, which records the developement of new principles, exhibits also the outbreakings of prejudice and selfishness. The deductions of Galileo, of Newton, of Harvey, and innumerable others, have been opposed and denounced, each in its turn; while their promoters have been vilified as empyrics or innovators. Nor has this been done by those only whose self love or worldly interests prompted them to exclude the truth, but by good and honourable men, whose prejudices were strong, and whose zeal was not guided by discretion. Such persons have frequently been found to shut their eyes against the plainest truths, to wrestle with their own convictions, and positively refuse even to listen to evidence. The same thing may happen with regard to education;—and this is no pleasing prospect to the lover of peace, who sets himself forward as a reformer in this noble work.—Change is inevitable. Teaching is an art; and it must, like all the other arts, depend for its improvement upon the investigations of science. Now, every one knows, that although the cultivation of chemistry, and other branches of natural science, has, of late years, given an extraordinary stimulus to the arts, yet the science of education, from which the art of teaching can alone derive its power, is one, beyond the threshold of which modern philosophy has scarcely entered. Changes, therefore, both in the theory and practice of teaching, may be anticipated;—and that these changes will be inconvenient and annoying to many, there can be no doubt. That individuals, in these circumstances, should be inclined to deprecate and oppose these innovations and improvements, is nothing more than might be expected; but that the improvements themselves should on that account be either postponed or abandoned, would be highly injurious. An enlightened system of education is peculiarly the property of the public, on which both personal, family, and national happiness in a great measure depends. These interests therefore must not be sacrificed to the wishes or the convenience of private individuals. The prosperity and happiness of mankind are at stake; and the welfare of succeeding generations will, in no small degree, be influenced by the establishment of sound principles in education at the present time. Nothing, therefore, should be allowed to mystify or cripple that science, upon which the spread and the permanence of all useful knowledge mainly rest.

The profession of teaching has long been characterised by certain habitual convictions, which Spencer undertook to shake rudely, and even to deride. The first of these convictions is that all education, physical, intellectual, and moral, must be authoritative, and need take no account of the natural wishes, tendencies, and motives of the ignorant and undeveloped child. The second dominating conviction is that to teach means to tell, or show, children what they ought to see, believe, and utter. Expositions by the teacher and books are therefore the true means of education. The third and supreme conviction is that the method of education which produced the teacher himself and the contemporary or earlier scholars, authors, and publicists, must be the righteous and sufficient method. Its fruits demonstrate its soundness, and make it sacred. Herbert Spencer, in the essays included in the present volume, assaulted all three of these firm convictions. Accordingly, the ideas on education which he put forth more than fifty years ago have penetrated educational practice very slowly particularly in England; but they are now coming to prevail in most civilised countries, and they will prevail more and more. Through him, the thoughts on education of Comenius, Montaigne, Locke, Milton, Rousseau, Pestalozzi, and other noted writers on this neglected subject are at last winning their way into practice, with the modifications or adaptations which the immense gains of the human race in knowledge and power since the nineteenth century opened have shown to be wise.
