Today I tried to read a fascinating article by Max Tegmark (MIT physicist) called “The Mathematical Universe (HT: Shane). Below I reproduced one of Tegmark’s diagrams of how “theories can be crudely organized into a family tree where each might, at least in principle, be derived from more fundamental ones above it.” T.O.E. (by the way) stands for “Theory of Everything”.
Tegmark’s sketch made me think of “religion” where the flow is the opposite direction. I quickly threw together the diagram below to illustrate the comparison that came to mind for me. In the religious mind, the basic units of our reality are our real experiences, and then humans create layers above it to support their world. The religious person’s world is not derived from the top down, though they would strongly disagree.
