By linking building theory to the emancipatory project of critique advanced by radical thinkers in our time, this work investigates the key conceptual and historical elements that culminate in an emancipatory theory of building entitled: 'Toward a philosophy of shelter’. Taking Marx as its only resource, this work proceeds with the conviction that our era is contemporaneous to Marx’s historical era. This means ‘not judging the validity of Marx from the perspective of the historical situation’, but rather, ‘demonstrating the validity of a Marxian perspective for a singular historical situation’, as ours. This work will therefore translate this perspective into seeing the situation of architecture through the eyes of Marx. All those concerned with the predicament in our current condition in which architecture must play a major social role in upholding the universal value of what Alain Badiou calls 'generic humanity' will take an interest in this work. In particular, architects, critics, scholars, and students inside the field of architecture who would be seeking the application of this universal value to a new theory of building will be a welcoming audience for this work.
