In the 1977 book, The Spectrum of Consciousness, American philosopher Ken Wilber sought to integrate the major schools of psychology along a continuum of different levels. Over ensuing years he further developed his integral theory approach within such disciplines as cultural anthropology, philosophy, sociology of religion, physics, healthcare, environmental studies, and postmodernism. The theory is based on the AQAL ("all quadrants, all levels") model, in which four quadrants represent the irreducible perspectives or dimensions of reality--subjective, intersubjective, objective, and interobjective--that must be consulted when attempting to understand any subject, along with the different levels of depth and complexity. In this work, Esbj繹rn-Hargens (John F. Kennedy U.) presents 16 papers from the first biennial Integral Theory Conference, held in 2008 for the purpose of exploring the further application, refinement, development, and critique of Wilber's approach across a range of disciplines.
