Infinite Series of Parallelograms

engels on history as geometry.Piet Mondrian, Composition with Large Red Plane, Yellow, Black, Gray and Blue (1921).

…history is made in such a way that the final result always arises from conflicts between many individual wills, of which each in turn has been made what it is by a host of particular conditions of life. Thus there are innumerable intersecting forces, an infinite series of parallelograms of forces which give rise to one resultant—the historical event.

— Friedrich Engels
