Modal Logic Considerations and Architecture

Abstract

The lecture deals with the concepts of reality, possibility, virtuality, and contingency in the context of considerations about the character of the specifically architectural conception of space. With the inclusion of the phenomenological-hermeneutic perspective, the view of the “significant” spatiality should open up. In this context, particular attention is paid to the so-called existential concept of possibility, which Martin Heidegger worked out within his existential ontology. The presentation examines to what extent the constitutive primacy of the existential project or the existential future reference is also decisive for the constitution of the significance of the architectural spatiality. On the basis of these insights, the difference from other ideas of projectivity, such as the projectivity of the architectural concept, can then be examined.
