In fact, all planetary masses are sympathetic-transferring-mediums, or intermediates, of this prime, luminous, dominant element. In the vibratory subdivision of matter, as progressive evolution has been analyzed, it is evident that these transfers of sympathetic force extend beyond the limits of our orbital range, from system to system, throughout the realms of space: these progressive systems becoming themselves, after a certain range of sympathetic motion, sympathetic intermediates, as included in the whole of one system, exemplified so beautifully in the cerebral convolutions, with their connective sympathy for each other; transferring as a whole on the focalizing centre, from which it radiates to all parts of the physical organism, controlling in all its intricate variety the sympathetic action, of our movements. "What is there that we really know?" asks Buckle. "We talk of the law of gravitation, and yet we know not what gravitation is; we talk of the conservation of force and distribution of forces, and we know not what forces are." "The vibratory principles now discovered in physics," says Hemstreet, "are so fine and attenuated that they become an analogy to mental or cerebral vibrations." Let us see what Keely's system of vibratory physics says of gravity, cohesion, etc. What is Gravity?--Gravity is an eternal existing condition in etheric space, from which all visible forms are condensed. Consequently, it is inherent in all forms of matter, visible and invisible. It is not subject to time nor space. It is an established connective link between all forms of matter from their birth, or aggregation. Time is annihilated by it, as it has already traversed space when the neutral centres of the molecules were established. Gravity, then, is nothing more than an attractive, sympathetic stream, flowing towards the neutral centre of the earth, emanating from molecular centres of neutrality; concordant with the earth's centre of neutrality, and seeking its medium of affinity with a power corresponding to the character of the molecular mass. What is Cohesion?--Cohesion is sympathetic negative attraction. It is the negative, vibratory assimilation, or aggregation, of the molecules, acting according to the density or compactness of the molecular groupings on their structures. The differing character of molecular densities, or molecular range of motion, represents differing powers of attraction. The lower the range of motions on the molecular vibrations of these structures, the greater is the attractive force that holds them together; and vice versâ.
