What I haven't seen is a suggestion for reducing the number of Great Ideas. I suggest it now, though not by eliminating any but by combining two, Time and Eternity. This came to mind when I noticed that the Outline of Topics for these two Great Ideas each contain 'Aeveternity as intermediate between time and eternity", Eternity 1b and Time 2b.
