"Pray do not stop," he said; "how is it that a delicate vibrating film of animal membrane can receive and convey sound to a pulpy organic mass that is destitute of elasticity, and which consists mostly of water, for the brain is such in structure, and vibrations like those you mention, can not, by your own theory, pass through it as vibrations through a sonorous material, or even reach from the tympanum of the ear to the nearest convolution of the brain." "I can not explain this, I admit," was my reply. "Pass that feature, then, and concede that this tympanic membrane is capable of materially affecting brain tissue by its tiny vibrations, how can that slimy, pulpy formation mostly made up of water, communicate with the soul of man, for you do not claim, I hope, that brain material is either mind, conscience, or soul?" I confessed my inability to answer or even to theorize on the subject, and recognizing my humiliation, I begged him to open the door to such knowledge. "The vibration of the atmosphere is necessary to man, as earthy man is situated," he said. "The coarser attributes known as matter formations are the crudities of nature, dust swept from space. Man's organism is made up of the roughest and lowest kind of space materials; he is surrounded by a turbulent medium, the air, and these various conditions obscure or destroy the finer attributes of his ethereal nature, and prevent a higher spiritual evolution. His spiritual self is enveloped in earth, and everywhere thwarted by earthy materials. He is insensible to the finer influences of surrounding media by reason of the overwhelming necessity of a war for existence with the grossly antagonistic materialistic confusion that everywhere confronts, surrounds, and pervades him. Such a conflict with extraneous matter is necessary in order that he may retain his earthy being, for, to remain a mortal, he must work to keep body and soul together. His organs of communication and perception are of 'earth, earthy'; his nature is cast in a mold of clay, and the blood within him gurgles and struggles in his brain, a whirlpool of madly rushing liquid substances, creating disorder in the primal realms of consciousness. He is ignorant of this inward turmoil because he has never been without it, as ignorant as he is of the rank odors of the gases of the atmosphere that he has always breathed, and can not perceive because of the benumbed olfactory nerves. Thus it is that all his subtler senses are inevitably blunted and perverted, and his vulgar nature preponderates. The rich essential part of his own self is unknown, even to himself. The possibility of delight and pleasure in an acquaintance with the finer attributes of his own soul is clouded by this shrouding materialistic presence that has, through countless generations, become a part of man, and he even derives most of his mental pleasures from such acts as tend to encourage the animal passions.
