Science is a strange kind of reality worship. We want to know what really is, out there in the physical world, independent of the vagaries of our internal experience. We try to find what’s true for everyone, all the time. It’s easy for me to forget that there are some contexts in which what is actually happening, in a measurable sense, is not what matters most. Sometimes, it hardly seems to matter at all. Corporate PR hacks, religious proselytizers and other propagandists understand this intuitively. If you tell people a story they want to believe, often they will go ahead and believe it, regardless of any countervailing evidence. They will thank Big Brother for increasing the chocolate ration from 30 grams to 20 grams per week. But this kind of disconnection of external from internal reality isn’t always sinister. Sometimes it isn’t even a disconnection so much as it is an orthogonality. Disconnection suggests that the two were once connected, or are intended to be one, but our internal experience is just not the same thing as external reality. They are related, but separated, by warm vitreous pools of light and hairy waveguides. There is some part of us which is intrinsic, or such a distant and distorted echo of the outside world as to be unrecognizable.
