Bernard Tschumi continues his talk by declaring that the paradox of architecture is that its conceptual elements and its actual, experiential elements are mutually exclusive, but also interdependent. He describes ways that architects have attempted to escape this paradox through historical and political refocusing, but sees this – exemplified by Constructivism – as a failure. Tschumi maintains that architecture is not necessary, and its power lies in this lack. It is like a firecracker, a pure expression of pleasure, which can neither be bought nor sold.
Tschumi responds to audience comments at length, focusing on space and interpretations of space.
