“This is a massive and violent schism and rupture in the internal organs of today's global culture and this is exactly why many social analysts believe that if some sort of reconciliation between science and religion is not forthcoming, the future of humanity is, at best, precarious.”

“Are the mystics and sages insane? Because they all tell variations on the same story, don't they? The story of awakening one morning and discovering you are one with the All, in a timeless and eternal and infinite fashion. Yes, maybe they are crazy, these divine fools. Maybe they are mumbling idiots in the face of the Abyss. Maybe they need a nice, understanding therapist. Yes, I'm sure that would help. But then, I wonder. Maybe the evolutionary sequence really is from matter to body to mind to soul to spirit, each transcending and including, each with a greater depth and greater consciousness and wider embrace. And in the highest reaches of evolution, maybe, just maybe, an individual's consciousness does indeed touch infinity — a total embrace of the entire Kosmos — a Kosmic consciousness that is Spirit awakened to its own true nature. It's at least plausible. And tell me: is that story, sung by mystics and sages the world over, any crazier than the scientific materialism story, which is that the entire sequence is a tale told by an idiot, full of sound and fury, signifying absolutely nothing? Listen very carefully: just which of those two stories actually sounds totally insane?”

“'What's my philosophy? In a word, integral. And what on earth — or in heaven — do I mean by "integral"? The dictionary meaning is fairly simple: "comprehensive, balanced, inclusive, essential for completeness." Short definition, tall order.”

“Human beings undergo psychological development. At each level or stage of development, they will see the world in a different way. Hence, each level of development has, as it were, a different religious belief or worldview. This does not make God or Spirit the result of human development; it does, however, make the ways in which humans conceive of God or Spirit the result of development. And this is where it gets really interesting.”
