There are many logicians who think that Bayesian inference can serve
as the entire foundation of rationality and is the most powerful form
of reasoning possible (the rationalist ideal).  What I'm 'destroying'
is that claim.  And I've done that.  But of course Bayes is still very
useful and powerful.

Because if the reductionist world-view is the correct one, the non-
reductionist world view should have serious inconsistencies, the fact
that there's not yet a conclusive technical rebuttal of Bohm counts as
evidence against reductionism.
