There are several different meanings of the words "religion" and "spirituality", all of which are important. The whole point about an integral or com… - Ken Wilber

An integral approach is based on one basic idea: no human mind can be 100% wrong. Or, we might say, nobody is smart enough to be wrong all the time. And that means, when it comes to deciding which approaches, methodologies, epistemologies, or ways or knowing are "correct", the answer can only be, "All of them." That is, all of the numerous practices or paradigms of human inquiry—including physics, chemistry, hermeneutics, collaborative inquiry, meditation, neuroscience, vision quest, phenomenology, structuralism, subtle energy research, systems theory, shamanic voyaging, chaos theory, developmental psychology—all of those modes of inquiry have an important piece of the overall puzzle of a total existence that includes, among other many things, health and illness, doctors and patients, sickness and healing.

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?

The integral vision, I believe, is more than happy to welcome empirical science as a part—a very important part—of the endeavor to befriend the Kosmos, to be attuned to its many moods and flavors and facets and forms. But a more integral psychology goes beyond that … With science we touch the True, the "It" of Spirit. With morals we touch the Good, the "We" of Spirit. What, then, would an integral approach have to say about the Beautiful, the "I" of Spirit itself? What is the Beauty that is in the eye of the Beholder? When we are in the eye of Spirit, the I of Spirit, what do we finally see?
