With Russian Mirror dolls The lowest level mirrors the largest level. The dolls gain structure as a series of fractals. Each doll on it's own terms is the same as any other doll. Under an infinite regress and progress each doll is a center point in size and shape.
Fractals are the movement from one position to another. Each loop is a movement from one position to another. Size is the difference in position. Position is the same thing existing in different states.
Places are things. For example if a ball is positioned in a field the position is a "thing" (ie the field). Dually if a spot is positioned on the ball, the position is a thing (ie the ball). Positions are things within things.
One phenomena is the back drop of another, thus being is grounded in isomorphism.
