The Integral Institute is a think-tank founded in 1998 by American author 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 ecology and sustainability, 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.
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. Notable members include Stuart Davis, Alex Grey, Deepak Chopra, Michael Murphy, Roger Walsh, Don Beck, Larry Dossey, Jon Kabat-Zinn, Ed Kowalczyk (from the band Live), and others.
Integral Research Center 
Integral Research Center provides support, including student grants, in the field of Integral Research (IR). The methodologies supported use the post-metaphysical position of Integral Theory and its practice to explore many phenomena in multiple disciplines. Among their grants is the Indigo Award for students who successfully apply Integral principles. The group's senior researcher is Sean Esbjörn-Hargens, Ph.D., an associate professor in the Integral Studies Department and Program Director of two Master of Arts degrees at John F. Kennedy University.
Integral Spiritual Center 
Integral Spiritual Center began as a collaborative endeavor bringing together respected spiritual teachers in the world today, who, in addition to fully embracing their own particular paths, came together to explore a trans-path path to the future. Through three teachers' gatherings, three seminars, numerous one-day events, dozens of conference calls, and a web presence, ISC has worked to "nourish the vision of Integral spirituality" and share it with thousands of practitioners around the world.
