"A space is not just a set of points, but a set together with a way of binding these points together into neighborhoods through well-defined relations of proximity or contiguity. In [...] Euclidean geometry these relations are specified by fixed lenghts... There exist other spaces however, where fixed distances cannot define proximities since distance do not remain fixed... The distinction between metric and nonmetric spaces in fundamental in Deleuzian ontology."
