Man and the space surrounding him are connected in many ways within a very complex system. Man's space is just a thin layer on the crust of the earth, consisting of the five elements which shape him and are shaped by him: Nature, in which he himself lives; the society which he has formed; the shells (or structures) which he builds; and the networks he constructs.

This is the real world of man, the anthropo-cosmos half way between the electron and the universe. It is with this world, and with its relationship to man, that I will deal here.
