There are many possible realities, infinitely many. Yet most of them are not . . . alive. Most of them are like books that no one ever actually wrote. A group-mind, like humanity's, lights up one given world. What makes this world different from some ghostly alternative universe is that we actually live here.

For whatever reason, we find it easier to "read" Hilbert Space patterns in terms of time. Yet the patterns exist outside of time. Thinking timelessly is not some unusual skill; when you remember last night's supper you sense a whole and not a chew-by-chew replay. To know a novel's action is to grasp the four-dimensional spacetime whole described.

The matter of color is more confusing. Not every property of a system can be stated as a definite spatio-temporal state of affairs. A system's tendency, for instance, to move from State A to State B, but not from State B to State A . . . a tendency like this is not any specific event which you can point to in space and time. These nonspecific properties correspond to overall gestalts in the Hilbert Space coloring. Alternating bands of red and green light might, for example, represent a particle which is moving from left to right but which has no specific location. A good mood could be a golden haze not tied to any particular cause.

At the most elemental level, reality evanesces into something called Schröedinger's Wave Function: a mathematical abstraction which is best represented as a pattern in an infinite-dimensional space, Hilbert Space. Each point of the Hilbert Space represents a possible state of affairs. The wave function for some one physical or mental system takes the form of, let us say, a coloring in of Hilbert Space. The brightly colored parts represent likely states for the system, the dim parts represent less probable states of affairs.

A person's lifeworm is a tangle of atomic worldlines. A braid. The dotty little atoms trace out smooth lines in spacetime: you are the pattern that these lines make up. there is no one single atom that is exclusively yours. I breathe an atom out, you breathe it in. Your garbage helps my tomatoes grow. And so the little spacetime threads weave us all together. The human race is a single vast tapestry, linked by our shared food and air. There are larger links as well: sperm, egg and umblilicus. Each family tree is an organic whole. Your spacetime body tapers back to the threads of mother's egg and father's sperm. And children, if you have them, are forever rooted in your flesh.
