Another danger of metatheory

From Esbjorn-Hargens in Metatheory for the Twenty-First Century (Routledge, 2015):

"[...] From time to time I arrived at the provocative idea that integral theory might not be as integral as it thinks or aspires to be. I came to feel that there is a real danger in assuming integral theory has included most of the enduring truths from many domains simply because it arguably has a framework and set of distinctions that could do so. [...] So I began to realize that within integral theory there might be some important pieces of reality not yet integrated, maybe we as integral metatheorists were putting some square metatheoretical pegs in round application holes, and some things just do not always fit neatly into the four quadrants" (102-03).
