Lecture V. — Pragmatism and Common Sense
In the last lecture we turned ourselves from the usual way of talking of the universe's oneness as a principle, sublime in all its blankness, towards a study of the special kinds of union which the universe enfolds. We found many of these to coexist with kinds of separation equally real. "How far am I verified?" is the question which each kind of union and each kind of separation asks us here, so as good pragmatists we have to turn our face towards experience, towards 'facts.'
Absolute oneness remains, but only as an hypothesis, and that hypothesis is reduced nowadays to that of an omniscient knower who sees all things without exception as forming one single systematic fact. But the knower in question may still be conceived either as an Absolute or as an Ultimate; and over against the hypothesis of him in either form the counter-hypothesis that the widest field of knowledge that ever was or will be still contains some ignorance, may be legitimately held. Some bits of information always may escape.
This is the hypothesis of NOETIC PLURALISM, which monists consider so absurd. Since we are bound to treat it as respectfully as noetic monism, until the facts shall have tipped the beam, we find that our pragmatism, tho originally nothing but a method, has forced us to be friendly to the pluralistic view. It MAY be that some parts of the world are connected so loosely with some other parts as to be strung along by nothing but the copula AND. They might even come and go without those other parts suffering any internal change. This pluralistic view, of a world of ADDITIVE constitution, is one that pragmatism is unable to rule out from serious consideration. But this view leads one to the farther hypothesis that the actual world, instead of being complete 'eternally,' as the monists assure us, may be eternally incomplete, and at all times subject to addition or liable to loss.
It IS at any rate incomplete in one respect, and flagrantly so. The very fact that we debate this question shows that our KNOWLEDGE is incomplete at present and subject to addition. In respect of the knowledge it contains the world does genuinely change and grow. Some general remarks on the way in which our knowledge completes itself—when it does complete itself—will lead us very conveniently into our subject for this lecture, which is 'Common Sense.'
To begin with, our knowledge grows IN SPOTS. The spots may be large or small, but the knowledge never grows all over: some old knowledge always remains what it was. Your knowledge of pragmatism, let us suppose, is growing now. Later, its growth may involve considerable modification of opinions which you previously held to be true. But such modifications are apt to be gradual. To take the nearest possible example, consider these lectures of mine. What you first gain from them is probably a small amount of new information, a few new definitions, or distinctions, or points of view. But while these special ideas are being added, the rest of your knowledge stands still, and only gradually will you 'line up' your previous opinions with the novelties I am trying to instil, and modify to some slight degree their mass.
You listen to me now, I suppose, with certain prepossessions as to my competency, and these affect your reception of what I say, but were I suddenly to break off lecturing, and to begin to sing 'We won't go home till morning' in a rich baritone voice, not only would that new fact be added to your stock, but it would oblige you to define me differently, and that might alter your opinion of the pragmatic philosophy, and in general bring about a rearrangement of a number of your ideas. Your mind in such processes is strained, and sometimes painfully so, between its older beliefs and the novelties which experience brings along.
Our minds thus grow in spots; and like grease-spots, the spots spread. But we let them spread as little as possible: we keep unaltered as much of our old knowledge, as many of our old prejudices and beliefs, as we can. We patch and tinker more than we renew. The novelty soaks in; it stains the ancient mass; but it is also tinged by what absorbs it. Our past apperceives and co-operates; and in the new equilibrium in which each step forward in the process of learning terminates, it happens relatively seldom that the new fact is added RAW. More usually it is embedded cooked, as one might say, or stewed down in the sauce of the old.
New truths thus are resultants of new experiences and of old truths combined and mutually modifying one another. And since this is the case in the changes of opinion of to-day, there is no reason to assume that it has not been so at all times. It follows that very ancient modes of thought may have survived through all the later changes in men's opinions. The most primitive ways of thinking may not yet be wholly expunged. Like our five fingers, our ear-bones, our rudimentary caudal appendage, or our other 'vestigial' peculiarities, they may remain as indelible tokens of events in our race-history. Our ancestors may at certain moments have struck into ways of thinking which they might conceivably not have found. But once they did so, and after the fact, the inheritance continues. When you begin a piece of music in a certain key, you must keep the key to the end. You may alter your house ad libitum, but the ground-plan of the first architect persists—you can make great changes, but you cannot change a Gothic church into a Doric temple. You may rinse and rinse the bottle, but you can't get the taste of the medicine or whiskey that first filled it wholly out.
