A term coined by Arthur Koestler. In Integral Theory, a holon refers to a whole that is simultaneously part of another whole, or “whole/part.” Whole atoms are parts of whole molecules, which themselves are parts of whole cells, and so on. There are individual holons and social holons. The main difference between the two is that individual holons have a subjective awareness or dominant monad (an “I”), while social holons have an intersubjective awareness, dominant mode of discourse, or predominant mode of resonance (a “We”/“Its”): social holons emerge when individual holons commune. Individual and social holons follow the twenty tenets. Lastly, “holon,” in the broadest sense, simply means “any whole that is a part of another whole,” and thus artifacts and heaps can loosely be considered “holons.”
