"You should reflect that man can not offer a satisfactory explanation of the fact that he can see with his eyes. In one respect, these so-called lower creatures are higher in the scale of life than man is, for they see (appreciate) without eyes. The surfaces of their bodies really are sources of perception, and seats of consciousness. Man must yet learn to see with his skin, taste with his fingers, and hear with the surface of his body. The dissected nerve, or the pupil of man's eye, offers to the physiologist no explanation of its intrinsic power. Is not man unfortunate in having to risk so much on so frail an organ? The physiologist can not tell why or how the nerve of the tongue can distinguish between bitter and sweet, or convey any impression of taste, or why the nerve of the ear communicates sound, or the nerve of the eye communicates the impression of sight. There is an impassable barrier behind all forms of nerve impressions, that neither the microscope nor other methods of investigation can help the reasoning senses of man to remove. The void that separates the pulp of the material nerve from consciousness is broader than the solar universe, for even from the most distant known star we can imagine the never-ending flight of a ray of light, that has once started on its travels into space. Can any man outline the bridge that connects the intellect with nerve or brain, mind, or with any form of matter? The fact that the surface of the bodies of some animals is capable of performing the same functions for these animals that the eye of man performs for him, is not more mysterious than is the function of that eye itself. The term darkness is an expression used to denote the fact that to the brain which governs the eye of man, what man calls the absence of light, is unrecognizable. If men were more magnanimous and less egotistical, they would open their minds to the fact that some animals really possess certain senses that are better developed than they are in man. The teachers of men too often tell the little they know and neglect the great unseen. The cat tribe, some night birds, and many reptiles can see better in darkness than in daylight. Let man compare with the nerve expanse of his own eye that of the highly developed eye of any such creature, and he will understand that the difference is one of brain or intellect, and not altogether one of optical vision surface. When men are able to explain how light can affect the nerves of their own eyes and produce such an effect on distant brain tissues as to bring to his senses objects that he is not touching, he may be able to explain how the energy in darkness can affect the nerve of the eye in the owl and impress vision on the brain of that creature. Should not man's inferior sense of light lead him to question if, instead of deficient visual power, there be not a deficiency of the brain capacity of man? Instead of accepting that the eye of man is incapable of receiving the
