Ferrer ’s ideas have often been discussed and debated ( sometimes heatedly ) within the pages of various peer-reviewed academic journals , including '' Journal of Consciousness Studies '' , '' International Journal of Transpersonal Studies '' , and '' Journal of Transpersonal Psychology '' . The harshest criticisms came from Wilber and his students , which is perhaps understandable as the publication of '' Revisioning '' arguably influenced Wilber ’s departure from the field . In October of 2001 , a month before the publication of '' Revisioning '' , Wilber suggested that Ferrer — together with figures such as Richard Rorty , Jean Baudrillard , Edward Said , and the late Wittgenstein — was responsible for the cultural confusion leading to the 9/11 terrorist attacks . Daryl Paulson claimed that anything of value in the book had been already said by Wilber , and the rest was , citing a personal communication from Wilber , “ a condensation of three decades of postmodern wrong turns … Ferrer ’s book basically marks the end of the transpersonal movement . ” One year later , however , Paulson retracted these views , stating : “ When I first read this book I hated it , but I have read and studied it for 2 years and find it one of the best books ever written on transpersonal psychology . ” In addition , Wilber wrote an essay charging '' Revisioning '' with falling into a performative contradiction ( i.e. , critiquing hierarchical rankings while upholding the superiority of its own approach ) and promoting what he called a flatland where no qualitative distinctions can be made . Ferrer responded stating that these critiques do not apply to his work . He argued that although his proposal does not privilege any tradition or type of spirituality on doctrinal , objectivist , or ontological grounds ( i.e. , saying that theism , monism , or nondualism corresponds to the nature of ultimate reality or is intrinsically superior ) , it does offer criteria for making qualitative distinctions on pragmatist and transformational grounds
