- ous reason. For the part cannot comprehend the whole of
which it is a part. It can but feel that there is a whole, in some mysterious way related to itself. But what that whole is, the conditions of its existence render it impossible that it should even guess.
Imagine the whole of the atmosphere divided into two great currents: a hot current continually ascending, and a cold current continually descending. And let the hot current represent the stream of conscious life, the cold current the stream of material things. To complete the simile, conceive that there is a sharp boundary between the two currents, so that atoms of air can never cross to and fro; while yet the conscious atoms in the hot current are aware of the existence of the unconscious atoms in the cold one. Now if the atoms or particles in the conscious current should be gifted with senses in proportion to their size, they will see and feel an infinitely minute portion both of the ascending current in which they they themselves are placed, and of the descending current they are passing by. But of the whole of the atmosphere of which they are themselves fragmentary portions they will be able to form no conception whatever. Its existence they will be aware of, for it will be needed to explain their own. But of its nature they will have no idea, except that in some undefinable way it is like themselves. Nor will they be able to form any picture of the cause which is continually carrying them upwards, and forcing their homologues in the opposite current downwards. While, if we suppose these opposite movements to represent the elements of Time and Space, they will be conscious of themselves only in terms of movement upwards, and of the unconscious particles in terms of movement downwards. They will suppose these two movements to be of the very essence of hot and cold particles, and will be able to conceive them only under these terms. Suppose, lastly, that at a certain point in their progress the hot particles become cold and pass into the opposing current, losing their individual, particular life, then their fellow-particles in the hot current will lose sight of them at that point, and they will be merged in the general stream of being to emerge again in their turn into the stream of conscis being.
Imperfect as this simile is, and as all such similes must be,
