2. Experience tells us only of individual things, and these things are innumerable. Our minds might have been so constructed as to be able to receive and retain an exact image of each of these various objects, one by one, as it came before us, but only in and for itself, without the power of comparing it with any of the others. But this is not our case: on the contrary, to compare and to contrast are among the most prominent and busy of our intellectual functions. Instinctively, even though unconsciously, we are ever instituting comparisons between the manifold phenomena of the external world, as we meet with them, criticizing, referring to a standard, collecting, analyzing them. Nay, as if by one and the same action, as soon as we perceive them, we also perceive that they are like each other or unlike, or rather both like and unlike at once. We apprehend spontaneously, even before we set about apprehending, that man is like man, yet unlike; and unlike a horse, a tree, a mountain, or a monument, yet in some, though not the same respects, like each of them. And in consequence, as I have said, we are ever grouping and discriminating, measuring and sounding, framing cross classes and cross divisions, and thereby rising from particulars to generals, that is from images to notions. In processes of this kind we regard things, not as they are in themselves, but mainly as they stand in relation to each other. We look at nothing simply for its own sake; we cannot look at any one thing without keeping our eyes on a multitude of other things besides. “Man” is no longer what he really is, an individual presented to us by our senses, but as we read him in the light of those comparisons and contrasts which we have made him suggest to us. He is attenuated into an aspect, or relegated to his place in a classification. Thus his appellation is made to suggest, not the real being which he is in this or that specimen of himself, but a definition. If I might use a harsh metaphor, I should say he is made the logarithm of his true self, and in that shape is worked with the ease and satisfaction of logarithms.
