Participatory Spirituality for the 21st Century
I haven't had a chance to read it yet, but the following article looks like a very relevant and timely one for us here at IPS. Wilber is responding to the recent association of Integral Theory with Critical Realism (via Sean at Meta-Integral), and likely also to critiques of Integral Theory offered by Critical Realists. Wilber said on a recent phone call that he was planning to issue a written defense of IT and critique of CR, in light of the emerging association of the two schools through Sean's work, so this appears to be it -- or the first of it.
Response to Critical Theory in Defense of Integral Theory
(I think he should have said "Critical Realism" rather than "Critical Theory" in his title; they aren't the same.)
Also, I'm not sure, but it's possible that my paper -- which he read and discussed with me -- might have also prompted this in part, since I mention in it a possible critique of IT from a CR point of view, i.e. that it is committing the epistemic fallacy, and I attempt to offer my own articulation of how integral avoids that fallacy.
Here's a link to the JITP issue (7:4, 12/12) with Marshall, Bhaskar and Wilber discussing the topic.
