In that case it should be quite easy to show what is wrong with my derivation of QM given in "Why Occam's Razor" or appendix D of my book. That derivation is exactly in the form of a proof that quantum mechanics is a consequence of "how we see the world". It is also not very long, and only requires a modicum of functional analysis, accessible to anybody who has studied quantum mechanics. > > To say that an external ontological reality does not necessarily > follow from intersubjective consistency is just setting the bar too > high.

It doesn't buy you anything, except unanswerable questions. To be fair, I don't think you do this Brent, but some people do: Edgar, Colin Hales and David Deutsch, to name a few.
