Phillipe Morel looks at the present-day economy using a number of little known but nonetheless essential epistemological assertions. The words of mathematicians, including those from previous centuries, shed light on the production of form in architecture, and on the economy in general. From this angle, we see that a contemporary, renewed epistemology enables us to grasp both the global and distinctive natures of a discipline such as architecture. To make a brief parallel, we could link the architectural analyses of Peter Eisenman with the polemical, urbanistic analyses of Rem Koolhaas. The challenge is to move beyond all opposition in an era that already achieved this and that seems, thanks to widespread computation, to have turned Carnaps Logical Structure of the World (1928) into a strictly positivist but nonetheless absolutely real standpoint.
