¿Cómo construir cuerpos individuales en el universo cartesiano?

This article argues that in the Cartesian Cosmology it is not clear how we can talk about or refer to individual bodies in the context of a compact universe. It defends that the concept of individual body inside of this Cosmology can be built as a fiction of the spirit. This concept can be constructed as the extension that is locked up in a maximal surface whose subdivisions have no relative movement between them. It is also shown that Cartesian Cosmology can be seen as a trivial model of M-theory.
