Norman Lockyer, in his book "The Chemistry of the Sun" says that, in dealing with molecules one feels as if dealing with more a mental than physical attribute "a sort of expression of free will on the part of the molecules." Also "The law that connects radiation with absorption and enables us to read the riddle set by the sun and stars, is then simply THE LAW OF SYMPATHETIC VIBRATION." The first quotation simply refers to the "dominant" or controlling property of matter, and the latter quotation aptly states Keely's identical theory of the constitution of matter, the principle of which is the cornerstone of his experimental researches.
