Here we observe the child taking the “me” ball (Sec. 411) and running around in space. There is nothing else of which to be aware; ergo, he is as yet unborn. Suddenly one “otherness” ball appears. Life begins. The two balls are mass-interattracted; they roll around on each other. A third ball appears and is mass-attracted; it rolls into the valley of the first two to form a triangle in which the three balls may involve-evolute. A fourth ball appears and is also mass-attracted; it rolls into the “nest” of the triangular group… and this stops all motion as the four balls become a self-stabilized system: the tetrahedron. (See Fig. 411.05.)
