We are bound to think tridimensionally.

A body has 3 dimensions: space, time and force.

Space in itself has 3 dimensions: height, length and depth (or height)

Time has 3 dimensions — duration, direction and change.

Force has 3 dimensions — direction, (...)

Is time coexistence? Then a thing while lasts coexists with itself? But since no two coexistents are equal, a coexistent is not equal to itself if it coexists with itself; hence change.

O tempo é a distância infinitesimal entre 2 coexistentes.
