Integral Theory as developed by Ken Wilber and other contemporary Integral scholars acknowledge many antecedent foundational influences, and proto-Integral thinkers. Curiously, the philosopher-statesman Jan Smuts’ theory of Holism is seldom acknowledged, although it has significantly contributed, albeit often implicitly, to the development of Integral Theory. This paper and presentation has two central aims: To point out that Smuts can be counted amongst one of the great Integral thinkers of the 20th Century; that Smuts’ notion of Holism had a significant influence (...) on the development of Integral Theory. This paper and presentation will provide a brief outline of Smuts’ theory of Holism as developed in his book Holism and Evolution and other philosophical essays. (shrink)
