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.

My thesis now is this, that OUR FUNDAMENTAL WAYS OF THINKING ABOUT THINGS ARE DISCOVERIES OF EXCEEDINGLY REMOTE ANCESTORS, WHICH HAVE BEEN ABLE TO PRESERVE THEMSELVES THROUGHOUT THE EXPERIENCE OF ALL SUBSEQUENT TIME. They form one great stage of equilibrium in the human mind’s development, the stage of common sense. Other stages have grafted themselves upon this stage, but have never succeeded in displacing it. Let us consider this common-sense stage first, as if it might be final.

In practical talk, a man’s common sense means his good judgment, his freedom from excentricity, his GUMPTION, to use the vernacular word. In philosophy it means something entirely different, it means his use of certain intellectual forms or categories of thought. Were we lobsters, or bees, it might be that our organization would have led to our using quite different modes from these of apprehending our experiences. It MIGHT be too (we cannot dogmatically deny this) that such categories, unimaginable by us to-day, would have proved on the whole as serviceable for handling our experiences mentally as those which we actually use.

If this sounds paradoxical to anyone, let him think of analytical geometry. The identical figures which Euclid defined by intrinsic relations were defined by Descartes by the relations of their points to adventitious co-ordinates, the result being an absolutely different and vastly more potent way of handling curves. All our conceptions are what the Germans call denkmittel, means by which we handle facts by thinking them. Experience merely as such doesn’t come ticketed and labeled, we have first to discover what it is. Kant speaks of it as being in its first intention a gewuehl der erscheinungen, a rhapsodie der wahrnehmungen, a mere motley which we have to unify by our wits. What we usually do is first to frame some system of concepts mentally classified, serialized, or connected in some intellectual way, and then to use this as a tally by which we ‘keep tab’ on the impressions that present themselves. When each is referred to some possible place in the conceptual system, it is thereby ‘understood.’ This notion of parallel ‘manifolds’ with their elements standing reciprocally in ‘one-to-one relations,’ is proving so convenient nowadays in mathematics and logic as to supersede more and more the older classificatory conceptions. There are many conceptual systems of this sort; and the sense manifold is also such a system. Find a one-to-one relation for your sense-impressions ANYWHERE among the concepts, and in so far forth you rationalize the impressions. But obviously you can rationalize them by using various conceptual systems.
