The Four Corners of Our Brain

Throughout religious, scientific, and humanist literature on ideas one finds categorical subdivisions that are four in number: the four corners of the Earth, the four cardinal directions, the four proteins constituting DNA, Maxwell's four equations, Toynbee's four societies, Pythagoras’ four elements of arithmetic, Pythagoras’ four elements, Hayden White's four aspects of imagination. The list is endless. From where does the “four” come? Why not five, or six, eight, or nine? Andersen tracks back to the beginnings of arithmetic utilized in the architecture of conceptual thinking. He finds the answer not only in the quadration of the human body as having four sides and giving a stabilizing structure to the brain but equally in the architecture of memory. Using the slot-theory of short-term memory processing, he demonstrates how easily the four-count comes to mind and how the brain resists moving on to five
