Integral theory
"The integral approach is committed to the full spectrum of consciousness as it manifests in all its extraordinary diversity... The integral vision embodies an attempt to take the best of both worlds, ancient and modern." (The Eye of Spirit, 1997)
"I have one major rule: Everybody is right. More specifically, everybody - including me - has some important pieces of truth, and all of those pieces need to be honored, cherished and included in a more gracious, spacious and compassionate embrace." (Introduction to Collected Works of Ken Wilber, 2000)
"The point is to unify the opposites, both positive and negative, by discovering a ground which transcends and encompasses both." (AZQuotes.com)
"To understand the whole, it is necessary to understand the parts. To understand the parts, it is necessary to understand the whole. Such is the circle of understanding." (The Simple Feeling of Being, 2004)
"'Saving the biosphere' depends first and foremost on human beings reaching mutual understanding and unforced agreement as to common ends." (Sex, Ecology, Spirituality, 1995, 2000)
