"The right phrase" How can we know that the Idea itself has any real existence apart from the Energy? Very strangely; by the fact that the Energy itself is conscious of referring all its acts to an existing and complete whole. Quite simply, every choice of an episode, or a phrase, or a word is made to conform to a pattern of the entire book, which is revealed by that choice as already existing. This truth, which is difficult to convey in explanation, is quite clear and obvious in experience. It manifests itself plainly enough when the writer says or thinks: “That is, or is not, the right phrase”—meaning that it is a phrase which does or does not correspond to the reality of the Idea.

Trees and graphs Show image 0 Show image 1 A tree is a kind of graph, but a graph can be considerably more complex than a tree. I have reason to believe, which for brevity’s sake I will treat elsewhere, that the most complex class of processes and structures we humans can consciously prescribe, reduces mathematically to a tree. A tree has a top, bottom, left and right. Its branches fan out from the trunk and they don’t intersect with one another. They are discrete, contiguous, identifiable objects which persist across time. Trees are Things. Software and websites, however, reduce to arbitrarily more complex structures: they are graphs. A graph has no meaningful orientation whatsoever. No sequence, no obvious start or end—at least none that we can intuit. It is better considered not as one Thing, but as a federation of Things, like the brain or a fungus network, or perhaps a composite artifact left behind from an ongoing process, like an ant colony or human city.
