"The fundamental conception of the Universe is force manifesting itself in rhythmical relations. "This definition is exhaustive, including both thought and extension, matter and mind. The law for the one is the law for the other. The distinction between them is simply relative, i.e., quantitative, not qualitative. "The rhythmic relations in which force acts are everywhere, under all conditions, and at all times, the same. They are found experimentally to be universally expressible by the mathematical relations of thirds." A summary by Professor Daniel Brinton of the University of Pennsylvania, on the very basis and essence of Keely's work. This is one of the more important papers in SVP. Professor Brinton spend much time in Keely's laboratory and applauded his work. 8.5" X 11"
