Wilber purports that many claims about non-rational states make a mistake he calls the pre/trans fallacy. According to Wilber, the non-rational stages of consciousness (what Wilber calls "pre-rational" and "trans-rational" stages) can be easily confused with one another. On Wilber's view, one can reduce trans-rational spiritual realization to pre-rational regression, or one can elevate pre-rational states to the trans-rational domain.
For example, Wilber claims that Freud and Jung commit this fallacy. Freud considered mystical realization to be a regression to infantile oceanic states. Wilber alleges that Freud thus commits a fallacy of reduction. Wilber thinks that Jung commits the converse form of the same mistake by considering pre-rational myths to reflect divine realizations. Likewise, pre-rational states may be misidentified as post-rational states.Wilber characterizes himself as having fallen victim to the pre/trans fallacy in his early work.
