The Spectrum of Consciousness (1993), Prologue, p. 6
Context: An argument can be legitimately sustained only if the participants are speaking about the same level. Argumentation would — for the most part — be replaced with something akin to Niels Bohr's principle of complementarity. Information from and about the different vibratory levels of bands of consciousness — although superficially as different as X-Rays and radio waves — would be integrated and synthesized into one spectrum, one rainbow. … Each band or level, being a particular manifestation of the spectrum, is what it is only by virtue of the other bands. The color blue is no less beautiful because it exists along side the other colors of a rainbow, and "blueness" itself depends upon the existence of the other colors, for if there were no color but blue, we would never be able to see it. In this type of synthesis, no approach, be it Eastern or Western, has anything to lose — rather, they all gain a universal context.
