No. Friedman has explicitly stated he basically thinks whenever we
look into any field of human thought we will find basic, fundamental,
and natural principles which, when formalized, have the consistency
strength of set theory (possibly extended with some large cardinal
axioms). Presumably because his research into these matters is (partly?)
funded by the Templeton Foundation, he's chosen to illustrate this point
-- made previously in terms of "concept calculus" etc. -- by means of
vaguely theological bandying about of somewhat arbitrary formalism.
