Integral theory is Ken Wilber's attempt to place a wide diversity of theories and thinkers into one single framework. It is portrayed as a "theory of everything" ("the living Totality of matter, body, mind, soul, and spirit"), trying "to draw together an already existing number of separate paradigms into an interrelated network of approaches that are mutually enriching." Wilber's integral theory has been applied by some in a limited range of domains. The Integral Institute publishes the Journal of Integral Theory and Practice.
