This blog has been partially adapted from A Literature Review of the Universal and Atomic Elements of Complex Cognition. The Systems pattern (5) (the interaction between the elements part and whole) exists in mind and nature. Nature (a.k.a., reality) organizes parts into wholes; so, in order for humans to adequately describe nature, we should, too. Humans naturally systematize things by breaking them down into parts and wholes automatically, which often leads to the creation of "groupings" or what we often erroneously call "categories." However, categories require something else: a Perspective.
