Christian Arnsperger, Ph.D. Economics, is Senior Research Fellow with the Belgian National Science Foundation and talented author of Full Spectrum Economics: Toward and Inclusive and Emancipatory Social Science, London: Routledge, 2010. He wrote that “It is a pleasure and an honor for me to have this opportunity to discuss my ideas on Integral Economics, alongside the highly promising advances offered in this issue by Kevin Bowman” (Arnsperger, 2010, p. 175).

In an editorial introduction, **Harris Friedman and Glenn Hartelius** (2009) wrote, of my ‘Holarchical Development’ article, that “Bowman thoughtfully reconsiders some
of the many implications of Ken Wilber’s All Quadrants All Levels (AQAL) theory, attending to some of its problems and suggesting some important extensions to this
approach.” “Bowman’s applications of Wilber’s work show the vital importance of transpersonal theory for understanding some of the most pressing problems of our time.”

**Ken Wilber** is integral philosophy’s most influential theorist. Robert Kegan, a leading developmental psychologist at Harvard University, has called Wilber a “national
treasure” (back cover of Wilber, 2000). In a recorded article review call, Ken Wilber, as editor-in-chief of The Journal of Integral Theory and Practice, called my
integral neoclassical economic growth model “an economic version of [Wilber’s] prime directive,” which “makes economics all of a sudden a moral and spiritual endeavor”
(Wilber and Bowman, 2010, 20 to 22 minutes in). He also called my reconciliation of sophisticated liberal, conservative, and radical views in my ‘Integral
Political Economy’ as “one of the most important places to begin” (Wilber and Bowman, 2010, 61 to 62 minutes in). In reviewing my ‘Integral Scientific Pluralism,’
article, Wilber stated that it is “interesting, worthwhile, and exiting” while congratulating me for “advancing the field” (Wilber and Bowman, 2012).

A leading integral theorist, **Sean Esbjorn-Hargens**, Executive Editor of the Journal of Integral Theory and Practice and CEO of Metaintegral Foundation, wrote in
his Executive Editor’s Introduction (Esbjorn-Hargens, 2010) that my ‘Integral Neoclassical Economic Growth’ article, along with Arnsperger (2008), “arguably
launched the field of Integral Economics.” Of my 2010 work, Sean characterized the ‘Integral Political Economy’ paper as “inspiring,” “making a number of
contributions to integral discourse” (Esbjorn-Hargens, 2010). There he also wrote that Bowman, in my ‘Financial Crisis’ article, “does an amazing job of
demonstrating the power of integral analysis…providing all integral scholar-practitioners with a valuable reference point of how to be creative with the
distinctions within Integral Theory and to use them to address the war of partial perspectives that so often characterizes our disciplines.” The 2010 JITP issue
containing articles by Arnsperger and myself “established Integral economics as a serious field of integral applications on par with some of the more established
fields.” “Bowman is skillful in demonstrating how his integral distinctions operate in the real world” (Esbjorn-Hargens, 2011). The ideas in my integral scientific
pluralism article “do heavy theoretical lifting and carve out new territory for Integral Theory…(with) many interesting implications for Integral
Research.” “Personally, I cannot wait to see where Bowman takes us next” (Esbjorn-Hargens, 2012).
