"Humanity has passed through a long history of one-sidedness and of a social condition that has always contained the potential of destruction, despite its creative achievements in technology. The great project of our time must be to open the other eye: to see all-sidedly and wholly, to heal and transcend the cleavage between humanity and nature that came with early wisdom."

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.
