In the first place, while the Brain is the Organ of the Mind--the Instrument that the Mind uses in producing Thought, still the Brain does _not_ do the thinking, nor is the brain-matter visible to the eye, the material instrument of thinking. The Brain (and other portions of the nervous systems, including the "little brains" or ganglia, found in various parts of the body) is composed of a certain substance--a fine form of Plasm, which however is but the ground-work of foundation for finer forms of Substance used in the production of Thought. Science has not discovered this finer Substance, for it is not visible to the eye, or to the finest instruments, but trained Occulists know that it exists. This fine Substance escapes the scalpel and microscope of the biologists and anatomists, and, consequently, their search for "Mind" in the Brain is futile. There is something more than "tissue to be irritated" in the Brain. But, remember, that this "something more" is still Substance, and not Mind itself. Thought is a form of "Excitement" in this fine brain-substance, which we may as well call Psycho-plasm, from the two Greek words meaning "the mind," and "a mold, or matrix," respectively--the combined word meaning the "mould or matrix of Mind," in other words the material Substance used by the Mind in which to "cast" or "mold" Thoughts. This Excitement in the Psychoplasm manifests in vibrations of its particles--for, like all Substance, it has "particles." All scientists agree that in the process of thinking there is an expenditure of Energy, and a "using-up" of material Substance. Just how this is effected, they do not know, but their experiments have shown that there is Energy manifested and used, and also Substance consumed. The secret of the production of Thought does not lie in the Brain or nervous system, which are but the material substratum upon which the Mind works, and which it uses as a mold or matrix for the production of Thought. Thought is the product of Mind directing Force upon Substance in the shape of Psychoplasm. And Energy is manifested in the production of Thought just as much as in the operation of the Law of Attraction, or Chemical Action. "_What_ Force and Energy?" may be asked. The answer is "_Mental_ Force!" But although the answer stares them right in the face, scientists deny that Mind contains Force or Energy within itself, and persist in thinking of Force as a "mechanical thing," or as necessarily derived from the common forms of Energy, such as Heat, Light or Electricity. They ignore the fact that Mind has a Finer Force which it uses to perform its work.
