ABSTRACT
In physics the Newtonian notion of absolute space, which in a certain way was related to that of I. Kant, has been replaced by the concept, originated by Leibnitz and expressed in physics by A. Einstein, of space as a system of relations. It is said that in the child and in primitive people space begins as a concept which is intimately linked to one's own person, and the same thing is observed in some organic diseases of the nervous system in which a regression to the primitive concepts is observed. One also hears in psychology the expression internal or inner space, which would be that in which our internal psychological experiences take place. Mathematical space is an ideal space or being, which in itself would be different from the already mentioned spaces, but which theorists would employ for a scientific conception of the physical world.
