Our intelligible universe is constructed out of the elements of Feeling according to certain classifications, the broadest of which is that into external and internal, object and subject. The abstractions Matter and Mind once formed and fixed in representative symbols, are easily accredited as two different Reels. But the separation is ideal, and is really a distinction of Aspects. We know ourselves as Body-Mind; we do not know ourselves as Body _and_ Mind, if by that be meant two coexistent independent Existents; and the illusion by which the two Aspects appear as two Reals may be made intelligible by the analysis of any ordinary proposition. For example, when we say “this fruit is sweet,” we express facts of Feeling--actual or anticipated--in abstract terms. The concrete facts are these: a colored feeling, a solid feeling, a sweet feeling, etc., have been associated together, and the colored, solid, sweet group is symbolized in the abstract term “fruit” But the color, solidity, and sweetness are also abstract terms, representing feelings associated in other groups, so that we find “fruit” which has no “sweetness”; and “sweetness” in other things besides “fruits.” Having thus separated ideally the “sweetness” from the “fruit”--which in the concrete sweet-fruit is not permissible--we easily come to imagine a real distinction. This is the case with the concrete living organism when we cease to consider it in its concrete reality, and fix our attention on its abstract terms--Body and Mind. We then think of Body apart from Mind, and believe in them as two Reals, though neither exists apart.
