"The point of departure of situography, or of plastic geometry, must be Situ analysis developed by Poincaré, and pushed in an egalitarian direction under the name topology. But all talk of equalities is openly excluded, if there aren't at least two elements to equalize. Thus the equivalence teaches us nothing about the unique or the polyvalence of the unique, which is in reality the essential domain of situ analysis, or topology. Our goal is to set a plastic and elementary geometry against egalitarian and Euclidean geometry, and with the help of both to go towards a geometry of variables, playful and differential geometry."
