What is Integral Theory?

When we say “integral” we are referring to Integral Theory, or AQAL, as pioneered by the contemporary American philosopher Ken Wilber. AQAL is an acronym that stands for a holisitic approach embracing

  • all Quadrants (dimensions of reality)
  • all Levels (of Development)
  • all Lines (of Development)
  • all States (of Consciousness, but also other states)
  • all Types (such as personality types, but also other types)

There are many other integral theories by other authors worth exploring. We at IEC find Ken Wilber’s model to be the most refined and encompassing theory available. As such it is a good minimum standard to cover the most essential ingredients and provide a shared language.
