The table before which we sit may be, as the scientist maintains, composed of dancing atoms, but it does not reveal itself to us as anything of the kind, and it is not with dancing atoms but a solid and motionless object that we live.
So remote is this "real" table--and most of the other "realities" with which science deals--that it cannot be discussed in terms which have any human value, and though it may receive out purely intellectual credence it cannot be woven into the pattern of life as it is led, in contradistinction to life as we attempt to think about it. Vibrations in the either are so totally unlike, let us say, the color purple that the gulf between them cannot be bridged, and they are, to all intents and purposes, not one but two separate things of which the second and less "real" must be the most significant for us. And just as the sensation which has led us to attribute an objective reality to a nonexistent thing which we call "purple" is more important for human life than the conception of vibrations of a certain frequency, so too the belief in God, however ill founded, has been more important in the life of man than the germ theory of decay, however true the latter may he.
We may, if we like, speak of consequence, as certain mystics love to do, of the different levels or orders of truth. We may adopt what is essentially a Platonist trick of thought and insist upon postulating the existence of external realities which correspond to the needs and modes of human feeling and which, so we may insist, have their being is some part of the universe unreachable by science. But to do so is to make an unwarrantable assumption and to be guilty of the metaphysical fallacy of failing to distinguish between a truth of feeling and that other sort of truth which is described as a "truth of correspondence," and it is better perhaps, at least for those of us who have grown up in an age of scientific thought, to steer clear of such confusions and to rest content with the admission that, though the universe with which science deals is the real universe, yet we do not and cannot have any but fleeting and imperfect contacts with it ; that the most important part of our lives-our sensations, emotions, desires, and aspirations-takes place in a universe of illusions which science can attenuate or destroy, but which it is powerless to enrich.
