“Well, now that we have seen each other,” said the Unicorn, “if you’ll believe in me, I’ll believe in you.”
—Lewis Carroll, Through the Looking-Glass
I want to talk about alternate realities. Not the multiverse kind or the virtual kind, but the kind that exist all around us. I watched Spotlight recently and none of us have been able to look away from that train-wreck of an election or this early administration, so hopefully enough of us have seen enough of all three of them to tie this post together.
We’re All in this Alone
Everybody, and I mean everybody, lives in their own reality. From the time you pop out of the womb, you begin aggregating a set of facts, or what seem to you to be facts, about the world around you. And that set of facts makes up your reality. The differences in our realities range from the sacred to the very mundane. Maybe I believe in God and you don’t, maybe you thought that dress was yellow and I thought it was blue. There may be some ultimate arbiter of what’s real—Plato’s realm of the forms or an Abrahamic God or a grand unifying theory of physics—but until one of those things speaks up, we’re each left with our own discrete perceptions of the world. When our differences are small, like that dress, they don’t impede our getting along. When they get bigger, they trip us up in proportion to the magnitude of the difference.
Almost nobody in the 15th century really thought the world was flat (and it may be a very long time since anybody’s actually thought that), but if we imagine, for the sake of argument, that Ferdinand and Isabella, the King and Queen of Spain in 1492, did think the Earth was flat, we can see how they and Christopher Columbus would have a difficult time plotting a new route to India.
