Walt Whitman mentions Fechner. Here is James's masterly summary of Fechner's general view in this regard. "The original sin, according to Fechner, of both our popular and our scientific thinking, is our inveterate habit of regarding the spiritual not as the rule but as an exception in the midst of nature. Instead of believing our life to be fed at the breasts of the greater life, our individuality to be sustained by the greater individuality, which must necessarily have more consciousness and more independence than all that it brings forth, we habitually treat whatever lies outside of our life as so much slag and ashes of life only; or if we believe in a Divine Spirit, we fancy him on the one side as bodiless and nature as soulless on the other. What comfort or peace, Fechner asks, can come from such a doctrine? The flowers wither at its breath, the stars turn into stone; our own body grows unworthy of our spirit and sinks into a tenement for carnal senses only. The book of nature turns into a volume on mechanics, in which whatever has life is treated as a sort of anomaly; a great chasm of separation yawns between us and all that is higher than ourselves, and God becomes a nest of thin abstractions." It is sufficiently well known that primitive man did not indulge in these "thin" views of nature. He interpreted the events and changes around him on the analogy of human activities; he looked upon them as manifestations of living wills. And indeed how could he do otherwise? For as yet he knew of no mode of activity other than his own. At first those objects and happenings were singled out which were of most practical interest, or which most distinctly forced themselves upon the attention. The beast of prey which threatened his life, the noisy brook, the roaring waves, the whisperings and cracklings in the woods--all argued the presence of life and will. So too with mountains, avalanches, sun, moon, stars, clouds, caves, fire, light, dark, life, death. So more especially with the storm which sweeps across the land, the thunder which shakes the solid earth, and the lightning which flashes from the one side of heaven to the other. Such were the phenomena on which his intellect worked, and in which he discovered all manner of useful or harmful causal relations. Such were the phenomena which produced in him emotions of awe and terror, joy and delight. To all of them he ascribed mental life like unto his own. Indeed it was only by such a view that he could at all understand them, or bring himself into living connection with them.
