Just as we envision all of space as really being out there, as really existing, we should also envision all of time as really being out there, as really existing, too. Past, present and future certainly appear to be distinct entities. But, as Einstein once said, “For we convinced physicists, the distinction between past, present and future is only an illusion, however persistent.” The only thing that’s real is the whole of spacetime. –Brian Greene, The Fabric of the Cosmos, p. 139, quoted at Naturalism.Org
I was already vaguely aware of this philosophical approach to time, which is known as Eternalism or the “Block Universe” theory, in which there is no objective flow of time, but rather a four-dimensional “block” of space-time in which all events “already” exist. My interest in this vertiginously counter-intuitive theory has been refreshed by this article at Naturalism.Org, one of my very favourite reality-based websites. I’m looking forward to following the links and bending my brain around these ideas, which like the stories of Borges are both thrillingly psychedelic and intellectually respectable.
