Integral Theory is an all-encompassing framework developed by Ken Wilber which explores the complexity of reality and offers an understanding that encompasses both traditional spiritual and scientific approaches to knowledge, uniting the two into an insightful and comprehensive synthesis. This idea is based on the axiom that reality is composed of four fundamental domains: body, mind, soul, and spirit. By addressing all four aspects of these domains and how they contribute to the whole, integral theory goes beyond simply looking at the parts, to attempting to gain a broader, more intricate understanding of the whole.
