Abstract

In the first part of this paper the Leibnizian theory of relations is presented as the metaphysical background of his concept of space. The structure of metaphysical space is dominated by the monads while geometrical aspects are neglected. In the second part the paper deals with Leibniz' concept of space in his mathematical works and especially in the Analysis Situs . What emerges is that the attempt to transfer philosophical arguments into mathematical structures fails because of the incompatibility of notions in different contexts. The same problem arises in his Characteristica universalis: Philosophy is not computable
