Chapter XXV: Theories of Knowledge - 2. Schools of Method
There are various systems of philosophy with characteristically different conceptions of the method of knowing. Some of them are named scholasticism, sensationalism, rationalism, idealism, realism, empiricism, transcendentalism, pragmatism, etc. Many of them have been criticized in connection with the discussion of some educational problem. We are here concerned with them as involving deviations from that method which has proved most effective in achieving knowledge, for a consideration of the deviations may render clearer the true place of knowledge in experience. In brief, the function of knowledge is to make one experience freely available in other experiences. The word 'freely' marks the difference between the principle of knowledge and that of habit. Habit means that an individual undergoes a modification through an experience, which modification forms a predisposition to easier and more effective action in a like direction in the future. Thus it also has the function of making one experience available in subsequent experiences. Within certain limits, it performs this function successfully. But habit, apart from knowledge, does not make allowance for change of conditions, for novelty. Prevision of change is not part of its scope, for habit assumes the essential likeness of the new situation with the old. Consequently it often leads astray, or comes between a person and the successful performance of his task, just as the skill, based on habit alone, of the mechanic will desert him when something unexpected occurs in the running of the machine. But a man who understands the machine is the man who knows what he is about. He knows the conditions under which a given habit works, and is in a position to introduce the changes which will re-adapt it to new conditions.
In other words, knowledge is a perception of those connections of an object which determine its applicability in a given situation. To take an extreme example; savages react to a flaming comet as they are accustomed to react to other events which threaten the security of their life. Since they try to frighten wild animals or their enemies by shrieks, beating of gongs, brandishing of weapons, etc., they use the same methods to scare away the comet. To us, the method is plainly absurd—so absurd that we fail to note that savages are simply falling back upon habit in a way which exhibits its limitations. The only reason we do not act in some analogous fashion is because we do not take the comet as an isolated, disconnected event, but apprehend it in its connections with other events. We place it, as we say, in the astronomical system. We respond to its connections and not simply to the immediate occurrence. Thus our attitude to it is much freer. We may approach it, so to speak, from any one of the angles provided by its connections. We can bring into play, as we deem wise, any one of the habits appropriate to any one of the connected objects. Thus we get at a new event indirectly instead of immediately—by invention, ingenuity, resourcefulness. An ideally perfect knowledge would represent such a network of interconnections that any past experience would offer a point of advantage from which to get at the problem presented in a new experience. In fine, while a habit apart from knowledge supplies us with a single fixed method of attack, knowledge means that selection may be made from a much wider range of habits.
Two aspects of this more general and freer availability of former experiences for subsequent ones may be distinguished. (See ante, ch. VI p. 3) (i) One, the more tangible, is increased power of control. What cannot be managed directly may be handled indirectly; or we can interpose barriers between us and undesirable consequences; or we may evade them if we cannot overcome them. Genuine knowledge has all the practical value attaching to efficient habits in any case. (ii) But it also increases the meaning, the experienced significance, attaching to an experience. A situation to which we respond capriciously or by routine has only a minimum of conscious significance; we get nothing mentally from it. But wherever knowledge comes into play in determining a new experience there is mental reward; even if we fail practically in getting the needed control we have the satisfaction of experiencing a meaning instead of merely reacting physically.
While the content of knowledge is what has happened, what is taken as finished and hence settled and sure, the reference of knowledge is future or prospective. For knowledge furnishes the means of understanding or giving meaning to what is still going on and what is to be done. The knowledge of a physician is what he has found out by personal acquaintance and by study of what others have ascertained and recorded. But it is knowledge to him because it supplies the resources by which he interprets the unknown things which confront him, fills out the partial obvious facts with connected suggested phenomena, foresees their probable future, and makes plans accordingly. When knowledge is cut off from use in giving meaning to what is blind and baffling, it drops out of consciousness entirely or else becomes an object of æsthetic contemplation. There is much emotional satisfaction to be had from a survey of the symmetry and order of possessed knowledge, and the satisfaction is a legitimate one. But this contemplative attitude is æsthetic, not intellectual. It is the same sort of joy that comes from viewing a finished picture or a well composed landscape. It would make no difference if the subject matter were totally different, provided it had the same harmonious organization. Indeed, it would make no difference if it were wholly invented, a play of fancy. Applicability to the world means not applicability to what is past and gone—that is out of the question by the nature of the case; it means applicability to what is still going on, what is still unsettled, in the moving scene in which we are implicated. The very fact that we so easily overlook this trait, and regard statements of what is past and out of reach as knowledge is because we assume the continuity of past and future. We cannot entertain the conception of a world in which knowledge of its past would not be helpful in forecasting and giving meaning to its future. We ignore the prospective reference just because it is so irretrievably implied.
Yet many of the philosophic schools of method which have been mentioned transform the ignoring into a virtual denial. They regard knowledge as something complete in itself irrespective of its availability in dealing with what is yet to be. And it is this omission which vitiates them and which makes them stand as sponsors for educational methods which an adequate conception of knowledge condemns. For one has only to call to mind what is sometimes treated in schools as acquisition of knowledge to realize how lacking it is in any fruitful connection with the ongoing experience of the students—how largely it seems to be believed that the mere appropriation of subject matter which happens to be stored in books constitutes knowledge. No matter how true what is learned to those who found it out and in whose experience it functioned, there is nothing which makes it knowledge to the pupils. It might as well be something about Mars or about some fanciful country unless it fructifies in the individual's own life.
At the time when scholastic method developed, it had relevancy to social conditions. It was a method for systematizing and lending rational sanction to material accepted on authority. This subject matter meant so much that it vitalized the defining and systematizing brought to bear upon it. Under present conditions the scholastic method, for most persons, means a form of knowing which has no especial connection with any particular subject matter. It includes making distinctions, definitions, divisions, and classifications for the mere sake of making them—with no objective in experience. The view of thought as a purely psychical activity having its own forms, which are applied to any material as a seal may be stamped on any plastic stuff, the view which underlies what is termed formal logic is essentially the scholastic method generalized. The doctrine of formal discipline in education is the natural counterpart of the scholastic method.
The contrasting theories of the method of knowledge which go by the name of sensationalism and rationalism correspond to an exclusive emphasis upon the particular and the general respectively—or upon bare facts on one side and bare relations on the other. In real knowledge, there is a particularizing and a generalizing function working together. So far as a situation is confused, it has to be cleared up; it has to be resolved into details, as sharply defined as possible. Specified facts and qualities constitute the elements of the problem to be dealt with, and it is through our sense organs that they are specified. As setting forth the problem, they may well be termed particulars, for they are fragmentary. Since our task is to discover their connections and to recombine them, for us at the time they are partial. They are to be given meaning; hence, just as they stand, they lack it. Anything which is to be known, whose meaning has still to be made out, offers itself as particular. But what is already known, if it has been worked over with a view to making it applicable to intellectually mastering new particulars, is general in function. Its function of introducing connection into what is otherwise unconnected constitutes its generality. Any fact is general if we use it to give meaning to the elements of a new experience. 'Reason' is just the ability to bring the subject matter of prior experience to bear to perceive the significance of the subject matter of a new experience. A person is reasonable in the degree in which he is habitually open to seeing an event which immediately strikes his senses not as an isolated thing but in its connection with the common experience of mankind. Without the particulars as they are discriminated by the active responses of sense organs, there is no material for knowing and no intellectual growth. Without placing these particulars in the context of the meanings wrought out in the larger experience of the past—without the use of reason or thought—particulars are mere excitations or irritations. The mistake alike of the sensational and the rationalistic schools is that each fails to see that the function of sensory stimulation and thought is relative to reorganizing experience in applying the old to the new, thereby maintaining the continuity or consistency of life.
The theory of the method of knowing which is advanced in these pages may be termed pragmatic. Its essential feature is to maintain the continuity of knowing with an activity which purposely modifies the environment. It holds that knowledge in its strict sense of something possessed consists of our intellectual resources—of all the habits that render our action intelligent. Only that which has been organized into our disposition so as to enable us to adapt the environment to our needs and to adapt our aims and desires to the situation in which we live is really knowledge. Knowledge is not just something which we are now conscious of, but consists of the dispositions we consciously use in understanding what now happens. Knowledge as an act is bringing some of our dispositions to consciousness with a view to straightening out a perplexity, by conceiving the connection between ourselves and the world in which we live.
