Abstract
The thesis aims to address the issue of 'philosophical topology' in Martin Heidegger's work and to identify its possible impact on contemporary architectural theory. Topology construes space and spatiality as a basic category for the constitution of meaning, in contrast to the traditionally prevalent category of Reason. This thesis argues that what is called 'reason' in Heidegger is not an a priori function of cognition, but is derived by the fundamental characteristic of human existence, which is its ability to create. But the act of creation in Heidegger, as will be demonstrated, is always a creation of what he calls “place" (or in German: “Ort”), thereby making topology equivalent to ontology. The most basic space-creating practice is architecture, which beget sense and creates meanings, and in doing so is directly related to the 'question of being'. It is therefore crucial to elaborate on the relationship between Heideggerian topology and architectural theory.
