Frank Visser (born September 17, 1958, Voorburg) is a Dutch author, theosophist, and psychologist of religion. He has written several books, including one on Ken Wilber. He is webmaster of Integral World (formerly called The World of Ken Wilber), a website dedicated to the philosophy of Ken Wilber, including both friendly and critical essays.[1]
According to a review by Daryl Paulson in the Journal of Transpersonal Psychology, "Frank Visser has written, arguably, the definitive book on Wilber's philosophy."[2]
He has worked in the field of book publishing in the nineties, but turned to web publishing around 1997. Has worked for Intel Europe between 1999 and 2005, was test manager of the Nokia "20Lives" game and webmaster of Peugeot.nl. Currently he is Service Desk manager for the Sara Lee coffee and tea brand websites in 20 countries at the Dutch internet company Lost Boys[3]
Integral World is the website maintained by Visser. The site hosts over 450 essays on Ken Wilber's Integral theory in a section called "The Reading Room".
In 2004 the site was renamed from the original title and domain name, "World of Ken Wilber", following an email from Ken Wilber asserting that criticisms on the site have nothing to do with his actual philosophy. Wilber maintains that the criticism at this website is of low quality. On the other hand, the website's authors claim that Ken Wilber simply avoids discussing their criticism.
Authors featured on Integral World include, among others: Michel Bauwens, Don Beck, Roland Benedikter, Elliot Benjamin, Edward Berge, Allan Combs, Susanne Cook-Greuter, Robert McDermott, Chris Dierkes, Mark Edwards, Sean Esbjörn-Hargens, Jorge Ferrer, Jordan S. Gruber, Wouter Hanegraaff, Ray Harris, Rod Hemsell, John Heron, Alan Kazlev, David Lane, Steve McIntosh, Jeff Meyerhoff, Joe Perez, Nancy Roof, Wayne Teasdale, Frank Visser, Lawrence Wollersheim, Michael Zimmerman
