“We can pool information about experiences, but never the experiences themselves. From family to nation, every human group is a society of island universes.”

The Believer interview (2013)
Context: Yeah, our view of reality, the one we conventionally take, is one among many. It’s pretty much a fact that our entire universe is a mental construct. We don’t actually deal with reality directly. We simply compose a picture of reality from what’s going on in our retinas, in the timpani of our ears, and in our nerve endings. We perceive our own perception, and that perception is to us the entirety of the universe. I believe magic is, on one level, the willful attempt to alter those perceptions. Using your metaphor of an aperture, you would be widening that window or changing the angle consciously, and seeing what new vistas it affords you.

This is attributed to Pierre Teilhard de Chardin in The Joy of Kindness (1993), by Robert J. Furey, p. 138; but it is attributed to G. I. Gurdjieff in Beyond Prophecies and Predictions: Everyone's Guide To The Coming Changes (1993) by Moira Timms, p. 62; neither cite a source. It was widely popularized by Wayne Dyer, who often quotes it in his presentations, crediting it to Chardin, as does Stephen Covey in Living the 7 Habits : Stories of Courage and Inspiration (2000), p. 47. Such statements could be considered paraphrases of Hegel's dictum that matter is spirit fallen into a state of self-otherness. Or any number of thousands of similarly vague quotes by hundreds of predecessors.
