How to Change Your Mind

This is the view of quantum physics, not some psychonaut—though it
is a very psychedelic theory. I mention it only because it lends some of the
authority of science to speculations that would otherwise sound utterly
lunatic. I still tend to think that consciousness must be confined to
brains, but I am less certain of this belief now than I was before I
embarked on this journey. Maybe it too has slipped out from between the
bars of that cage. Mysteries abide. But this I can say with certainty: the
mind is vaster, and the world ever so much more alive, than I knew when
I began.
