The Integral Institute is a think-tank founded in 1998 by American philosopher, psychologist, and mystic Ken Wilber. The purpose of the Institute is to gather and attempt to integrate the various viewpoints found in a number of major fields of knowledge. For example, the Integral Institute currently has a number of branches including Integral psychology, Integral business, Integral politics, Integral medicine, Integral education, Integral law and criminal justice, Integral art, and Integral spirituality. This attempt to integrate the knowledge base of a particular field is based on the notion that differing opinions are often true but partial versions of actual reality. Various schools of thought in a particular subject then, rather than being winner-take-all competitors, are seen as unique but partial contributors to a more realistic or Integral whole. These schools of thought can be likened to the parable about the blind men standing around the elephant each describing what they feel - one feels the elephant's feet, one feels the ears, the trunk, etc. Integral theory, in a nutshell, says that these viewpoints can be integrated to create a more complete and accurate version of reality. Notable members include Stuart Davis (musician), Alex Grey (visionary artist), Deepak Chopra (New Age author), Michael Murphy, Roger Walsh, Don Beck, Larry Dossey, Jon Kabat-Zinn, Ed Kowalczyk (from the band Live), and others.
Integral Institute outreach is occurring through a variety of projects. These include the Integral Institute Workshop Series, Integral Naked, Integral Life Practice, Integral University, and the Integral Spiritual Center.
