For miscellaneous discussions and remarks not suitable for top-level posts even in the Discussion section, let alone in Main.
(Naturally, if a discussion gets too unwieldy, celebrate by turning it into a top-level post, just like in the good old days.)
Silly hypothesis: all reductionists are actually p-zombies. Lacking qualia, and generalizing from one example, we assume incorrectly that "qualia" must refer to something that our own brains do, and wind up constructing theories that try to explain qualia in terms of material processes.
I remember that being proposed seriously by a commenter during the Sequences.
