Scroll to zoom, drag to pan, or use the buttons above (+ / − / 0 keys also work). Hover a node to highlight its path to the center and the subtree beneath it. How to read this The center holds the topic. The six branches fan out bilaterally — three on each side — each in its own color. Sub-branches nest three levels deep under each top-level branch. Hover a leaf to trace the path back to the center; hover a branch to see everything it contains.
This is the shape the topic has when you try to hold the whole field in your head at once. It is not an argument; it is a scaffold. The essays argue against or within scaffolds like this one.
