In science today we are witnessing a general shift away from the assumption that the true fundamental nature of matter can be considered from the point of view of sub- stance (particles, quanta) to the concept that the fundamental nature of the material world is knowable only through its underlying patterns of wave forms. Both our organs of perception and the truly phenomenal world we perceive seem to be best understood as systems of pure pattern, or as geometric structures of form and proportion. Therefore, when many ancient cultures chose to examine reality through the metaphors of geometry and music (music being the study of the proportional laws of sound frequency), they were already very close to the position of our most contemporary science. Professor Amstutz of the Mineralogical Institute at the University of Heidelberg recently said: “Matter’s latticed waves are spaced at intervals corresponding to the frets on a harp or guitar with analogous sequences of overtones arising from each fundamental. The science of musical harmony is in these terms practically identical with the science of symmetry in crystals.” The point of view of modern force field theory and wave mechanics corresponds to the ancient geometric and harmonic vision of universal order as being an interwoven configuration of wave patterns.
