III. The Modality of the Process of Teaching.

§ 122. Now that we have learned something of the relation of the teacher to the taught, and of the process of learning itself, we must examine the mode and manner of instruction. This may have (1) the character of contingency: the way in which our immediate existence in the world, our life, teaches us; or it may be given (2) by the printed page; or (3) it may take the shape of formal oral instruction.

§ 123. (1) For the most, the best, and the mightiest things that we know we are indebted to Life itself. The sum of perceptions which a human being absorbs into himself up to the fourth or fifth year of his life is incalculable; and after this time we involuntarily gain by immediate contact with the world countless ideas. But especially we understand by the phrase "the School of Life," the ethical knowledge which we gain by what happens in our own lives.

—If one says, Vitæ non scholæ discendum est, one can also say, Vita docet. Without the power exercised by the immediate world our intelligence would remain abstract and lifeless.—

§ 124. (2) What we learn through books is the opposite of that which we learn through living. Life forces upon us the knowledge it has to give; the book, on the contrary, is entirely passive. It is locked up in itself; it cannot be altered; but it waits by us till we wish to use it. We can read it rapidly or slowly; we can simply turn over its leaves—what in modern times one calls reading;—we can read it from beginning to end or from end to beginning; we can stop, begin again, skip over passages, or cut them short, as we like. To this extent the book is the most convenient means for instruction. If we are indebted to Life for our perceptions, we must chiefly thank books for our understanding of our perceptions. We call book-instruction "dead" when it lacks, for the exposition which it gives, a foundation in our perceptions, or when we do not add to the printed description the perceptions which it implies; and the two are quite different.

§ 125. Books, as well as life, teach us many things which we did not previously intend to learn directly from them. From foreign romances e.g. we learn, first of all, while we read them for entertainment, the foreign language, history or geography, &c. We must distinguish from such books as those which bring to us, as it were accidentally, a knowledge for which we were not seeking, the books which are expressly intended to instruct. These must (a) in their consideration of the subject give us the principal results of any department of knowledge, and denote the points from which the next advance must be made, because every science arises at certain results which are themselves again new problems; (b) in the consideration of the particulars it must be exhaustive, i.e. no essential elements of a science must be omitted. But this exhaustiveness of execution has different meanings according to the stand-points of those for whom it is made. How far we shall pass from the universality of the principal determinations into the multiplicity of the Particular, into the fulness of detail, cannot be definitely determined, and must vary, according to the aim of the book, as to whether it is intended for the apprentice, the journeyman, or the master; (c) the expression must be precise, i.e. the maximum of clearness must be combined with the maximum of brevity.

—The writing of a text-book is on this account one of the most difficult tasks, and it can be successfully accomplished only by those who are masters in a science or art, and who combine with great culture and talent great experience as teachers. Unfortunately many dabblers in knowledge undervalue the difficulty of writing text-books because they think that they are called upon to aid in the spread of science, and because the writing of compendiums has thus come to be an avocation, so that authors and publishers have made out of text-books a profitable business and good incomes. In all sciences and arts there exists a quantity of material which is common property, which is disposed of now in one way, now in another. The majority of compendiums can be distinguished from each other only by the kind of paper, printing, the name of the publisher or bookseller, or by arbitrary changes in the arrangement and execution. The want of principle with which this work is carried on is incredible. Many governments have on this account fixed prices for text-books, and commissioners to select them. This in itself is right and proper, but the use of any book should be left optional, so that the one-sidedness of a science patronized by government as it were patented, may not be created through the pressure of such introduction. A state may through its censorship oppose poor text-books, and recommend good ones; but it may not establish as it were a state-science, a state-art, in which only the ideas, laws and forms sanctioned by it shall be allowed. The Germans are fortunate, in consequence of their philosophical criticism, in the production of better and better text-books, among which may be mentioned Koberstein's, Gervinus', and Vilmar's Histories of Literature, Ellendt's General History, Blumenbach's and Burmeister's Natural History, Marheineke's text-book on Religion, Schwegler's History of Philosophy, &c. So much the more unaccountable is it that, with such excellent books, the evil of such characterless books, partly inadequate and partly in poor style, should still exist when there is no necessity for it. The common style of paragraph-writing has become obnoxious, under the name of Compendium-style, as the most stiff and affected style of writing.—

§ 126. A text-book must be differently written according as it is intended for a book for private study or for purposes of general circulation. If the first, it must give more, and must develop more clearly the internal relations; if the second, it should be shorter, and proceed from axiomatic and clear postulates to their signification, and these must have an epigrammatic pureness which should leave something to be guessed. Because for these a commentary is needed which it is the teacher's duty to supply, such a sketch is usually accompanied by the fuller text-book which was arranged for private study.

—It is the custom to call the proper text-book the "small" one, and that which explains and illustrates, the "large" one. Thus we have the Small and the Large Gervinus, &c.—

§ 127. (3) The text-book which presupposes oral explanation forms the transition to Oral instruction itself. Since speech is the natural and original form in which mind manifests itself, no book can rival it. The living word is the most powerful agent of instruction. However common and cheap printing may have rendered books as the most convenient means of education—however possible may have become, through the multiplication of facilities for intercourse and the rapidity of transportation, the immediate viewing of human life, the most forcible educational means, nevertheless the living word still asserts its supremacy. In two cases especially is it indispensable: one is when some knowledge is to be communicated which as yet is found in no compendium, and the other when a living language is to be taught, for in this case the printed page is entirely inadequate. One can learn from books to understand Spanish, French, English, Danish, &c., but not to speak them; to do this he must hear them, partly that his ear may become accustomed to the sounds, partly that his vocal organs may learn correctly to imitate them.
