abstract: Prolegomena to a New Architectural Metaphysics What if architecture is of the cosmos? For too long, we have constrained architecture to an exclusively human affair. We have disregarded intriguing architectural experiments of human species other than Homo sapiens, understudied space-morphing capacities of myriad animals, and overlooked thetectonic ingenuity of the Earth and the world-building activities of the cosmos. That is, we have failed to envision architecture as a strategy of existence – not just our existence, but existence as such. This special section, the third in a yearlong series conceived with Sanford Kwinter (Log 49, 51, and 52),challenges the conventional definitions and anthropocentricfoundations of architecture, journeys through different gradations of an all-pervading constructive continuum, and entertains the heterodox possibility that architecture is a cosmic art.
