that it is impossible to draw sharp lines, such as would enable us to say, "Here my experience ends; there yours begins." In so far as we are partners in common undertakings, the things which others communicate to us as the consequences of their particular share in the enterprise blend at once into the experience resulting from our own special doings. The ear is as much an organ of experience as the eye or hand; the eye is available for reading reports of what happens beyond its horizon. Things remote in space and time affect the issue of our actions quite as much as things which we can smell and handle. They really concern us, and, consequently, any account of them which assists us in dealing with things at hand falls within personal experience.
Information is the name usually given to this kind of subject matter. The place of communication in personal doing supplies us with a criterion for estimating the value of informational material in school. Does it grow naturally out of some question with which the student is concerned? Does it fit into his more direct acquaintance so as to increase its efficacy and deepen its meaning? If it meets these two requirements, it is educative. The amount heard or read is of no importance—the more the better, provided the student has a need for it and can apply it in some situation of his own.
But it is not so easy to fulfill these requirements in actual practice as it is to lay them down in theory. The extension in modern times of the area of intercommunication; the invention of appliances for securing acquaintance with remote parts of the heavens and bygone events of history; the cheapening of devices, like printing, for recording and distributing information—genuine and alleged—have created an immense bulk of communicated subject matter. It is much easier to swamp a pupil with this than to work it into his direct experiences. All too frequently it forms another strange world which just overlies the world of personal acquaintance. The sole problem of the student is to learn, for school purposes, for purposes of recitations and promotions, the constituent parts of this strange world. Probably the most conspicuous connotation of the word knowledge for most persons to-day is just the body of facts and truths ascertained by others; the material found in the rows and rows of atlases, cyclopedias, histories, biographies, books of travel, scientific treatises, on the shelves of libraries.
The imposing stupendous bulk of this material has unconsciously influenced men's notions of the nature of knowledge itself. The statements, the propositions, in which knowledge, the issue of active concern with problems, is deposited, are taken to be themselves knowledge. The record of knowledge, independent of its place as an outcome of inquiry and a resource in further inquiry, is taken to be knowledge. The mind of man is taken captive by the spoils of its prior victories; the spoils, not the weapons and the acts of waging the battle against the unknown, are used to fix the meaning of knowledge, of fact, and truth.
If this identification of knowledge with propositions stating information has fastened itself upon logicians and philosophers, it is not surprising that the same ideal has almost dominated instruction. The "course of study" consists largely of information distributed into various branches of study, each study being subdivided into lessons presenting in serial cutoff portions of the total store. In the seventeenth century, the store was still small enough so that men set up the ideal of a complete encyclopedic mastery of it. It is now so bulky that the impossibility of any one man's coming into possession of it all is obvious. But the educational ideal has not been much affected. Acquisition of a modicum of information in each branch of learning, or at least in a selected group, remains the principle by which the curriculum, from elementary school through college, is formed; the easier portions being assigned to the earlier years, the more difficult to the later. The complaints of educators that learning does not enter into character and affect conduct; the protests against memoriter work, against cramming, against gradgrind preoccupation with "facts," against devotion to wire-drawn distinctions and ill-understood rules and principles, all follow from this state of affairs. Knowledge which is mainly second-hand, other men's knowledge, tends to become merely verbal. It is no objection to information that it is clothed in words; communication necessarily takes place through words. But in the degree in which what is communicated cannot be organized into the existing experience of the learner, it becomes mere words: that is, pure sense-stimuli, lacking in meaning. Then it operates to call out mechanical reactions, ability to use the vocal organs to repeat statements, or the hand to write or to do "sums."
To be informed is to be posted; it is to have at command the subject matter needed for an effective dealing with a problem, and for giving added significance to the search for solution and to the solution itself. Informational knowledge is the material which can be fallen back upon as given, settled, established, assured in a doubtful situation. It is a kind of bridge for mind in its passage from doubt to discovery. It has the office of an intellectual middleman. It condenses and records in available form the net results of the prior experiences of mankind, as an agency of enhancing the meaning of new experiences. When one is told that Brutus assassinated Caesar, or that the length of the year is three hundred sixty-five and one fourth days, or that the ratio of the diameter of the circle to its circumference is 3.1415. . . one receives what is indeed knowledge for others, but for him it is a stimulus to knowing. His acquisition of knowledge depends upon his response to what is communicated.
3. Science or Rationalized Knowledge. Science is a name for knowledge in its most characteristic form. It represents in its degree, the perfected outcome of learning,—its consummation. What is known, in a given case, is what is sure, certain, settled, disposed of; that which we think with rather than that which we think about. In its honorable sense, knowledge is distinguished from opinion, guesswork, speculation, and mere tradition. In knowledge, things are ascertained; they are so and not dubiously otherwise. But experience makes us aware that there is difference between intellectual certainty of subject matter and our certainty. We are made, so to speak, for belief; credulity is natural. The undisciplined mind is averse to suspense and intellectual hesitation; it is prone to assertion. It likes things undisturbed, settled, and treats them as such without due warrant. Familiarity, common repute, and congeniality to desire are readily made measuring rods of truth. Ignorance gives way to opinionated and current error,—a greater foe to learning than ignorance itself. A Socrates is thus led to declare that consciousness of ignorance is the beginning of effective love of wisdom, and a Descartes to say that science is born of doubting.
We have already dwelt upon the fact that subject matter, or data, and ideas have to have their worth tested experimentally: that in themselves they are tentative and provisional. Our predilection for premature acceptance and assertion, our aversion to suspended judgment, are signs that we tend naturally to cut short the process of testing. We are satisfied with superficial and immediate short-visioned applications. If these work out with moderate satisfactoriness, we are content to suppose that our assumptions have been confirmed. Even in the case of failure, we are inclined to put the blame not on the inadequacy and incorrectness of our data and thoughts, but upon our hard luck and the hostility of circumstance. We charge the evil consequence not to the error of our schemes and our incomplete inquiry into conditions (thereby getting material for revising the former and stimulus for extending the latter) but to untoward fate. We even plume ourselves upon our firmness in clinging to our conceptions in spite of the way in which they work out.
Science represents the safeguard of the race against these natural propensities and the evils which flow from them. It consists of the special appliances and methods which the race has slowly worked out in order to conduct reflection under conditions whereby its procedures and results are tested. It is artificial (an acquired art), not spontaneous; learned, not native. To this fact is due the unique, the invaluable place of science in education, and also the dangers which threaten its right use. Without initiation into the scientific spirit one is not in possession of the best tools which humanity has so far devised for effectively directed reflection. One in that case not merely conducts inquiry and learning without the use of the best instruments, but fails to understand the full meaning of knowledge. For he does not become acquainted with the traits that mark off opinion and assent from authorized conviction. On the other hand, the fact that science marks the perfecting of knowing in highly specialized conditions of technique renders its results, taken by themselves, remote from ordinary experience—a quality of aloofness that is popularly designated
