Knowledge and Understanding
"Knowledge is acquired when we succeed in fitting a new experience into the system of concepts based upon our old experiences. Understanding comes when we liberate ourselves from the old and so make possible a direct, unmediated contact with the new, the mystery, moment by moment, of our existence. The new is the given on every level of experience — given perceptions, given emotions and thoughts, given states of unstructured awareness, given relationships with things and persons. The old is our home-made system of ideas and word patterns. It is the stock of finished articles fabricated out of the given mystery by memory and analytical reasoning, by habit and the automatic associations of accepted notions. Knowledge is primarily a knowledge of these finished articles. Understanding is primarily direct awareness of the raw material.
Knowledge is always in terms of concepts and can be passed on by means of words or other symbols. Understanding is not conceptual, and therefore cannot be passed on. It is an immediate experience, and immediate experience can only be talked about (very inadequately), never shared. Nobody can actually feel another’s pain or grief, another’s love or joy or hunger. And similarly nobody can experience another’s understanding of a given event or situation. There can, of course, be knowledge of such an understanding, and this knowledge may be passed on in speech or writing, or by means of other symbols. Such communicable knowledge is useful as a reminder that there have been specific understandings in the past, and that understanding is at all times possible. But we must always remember that knowledge of understanding is not the same thing as the understanding, which is the raw material of that knowledge. It is as different from understanding as the doctor’s prescription for penicillin is different from penicillin.
Understanding is not inherited, nor can it be laboriously acquired. It is something which, when circumstances are favorable, comes to us, so to say, of its own accord. All of us are knowers, all the time; it is only occasionally and in spite of ourselves that we directly understand the mystery of given reality. Consequently we are very seldom tempted to equate understanding with knowledge. Of the exceptional men and women, who have understanding in every situation, most are intelligent enough to see that understanding is different from knowledge and that conceptual systems based upon past experience are as necessary to the conduct of life as are spontaneous insights into new experiences. For these reasons the mistake of identifying understanding with knowledge is rarely perpetrated and therefore poses no serious problem.
How different is the case with the opposite mistake, the mistake of supposing that knowledge is the same as understanding and interchangeable with it! All adults possess vast stocks of knowledge. Some of it is correct knowledge, some of it is incorrect knowledge, and some of it only looks like knowledge and is neither correct nor incorrect; it is merely meaningless. That which gives meaning to a proposition is not (to use the words of an eminent contemporary philosopher, Rudolf Carnap) “the attendant images or thoughts, but the possibility of deducing from it perceptive propositions, in other words the possibility of verification. To give sense to a proposition, the presence of images is not sufficient, it is not even necessary. We have no image of the electro-magnetic field, nor even, I should say, of the gravitational field; nevertheless the proposition which physicists assert about these fields have a perfect sense, because perceptive propositions are deductible from them.”
Metaphysical doctrines are propositions which cannot be operationally verified, at least on the level of ordinary experience. They may be expressive of a state of mind, in the way that lyrical poetry is expressive; but they have no assignable meaning. The information they convey is only pseudo-knowledge. But the formulators of metaphysical doctrines and the believers in such doctrines have always mistaken this pseudo-knowledge for knowledge and have proceeded to modify their behavior accordingly. Meaningless pseudo-knowledge has at all times been one of the principal motivators of individual and collective action. And that is one of the reasons why the course of human history has been so tragic and at the same time so strangely grotesque. Action based upon meaningless pseudo-knowledge is always inappropriate, always beside the point, and consequently always results in the kind of mess mankind has always lived in — the kind of mess that makes the angels weep and the satirists laugh aloud.
Correct or incorrect, relevant or meaningless, knowledge and pseudo-knowledge are as common as dirt and are therefore taken for granted. Understanding, on the contrary, is as rare, very nearly, as emeralds, and so is highly prized. The knowers would dearly love to be understanders; but either their stock of knowledge does not include the knowledge of what to do in order to be understanders; or else they know theoretically what they ought to do, but go on doing the opposite all the same. In either case they cherish the comforting delusion that knowledge and, above all, pseudo-knowledge are understanding. Along with the closely related errors of over-abstraction, over-generalization and over-simplification, this is the commonest of all intellectual sins and the most dangerous.
Of the vast sum of human misery about one third, I would guess, is unavoidable misery. This is the price we must pay for being embodied, and for inheriting genes which are subject to deleterious mutations. This is the rent extorted by Nature for the privilege of living on the surface of a planet, whose soil is mostly poor, whose climates are capricious and inclement, and whose inhabitants include a countless number of micro-organisms capable of causing in man himself, in his domestic animals and cultivated plants, an immense variety of deadly or debilitating diseases. To these miseries of cosmic origin must be added the much larger group of those avoidable disasters we bring upon ourselves. For at least two thirds of our miseries spring from human stupidity, human malice and those great motivators and justifiers of malice and stupidity, idealism, dogmatism and proselytizing zeal on behalf of religious or political idols. But zeal, dogmatism and idealism exist only because we are forever committing intellectual sins. We sin by attributing concrete significance to meaningless pseudo-knowledge; we sin in being too lazy to think in terms of multiple causation and indulging instead in over-simplification, over-generalization and over-abstraction; and we sin by cherishing the false but agreeable notion that conceptual knowledge and, above all, conceptual pseudo-knowledge are the same as understanding.
