Above is the video from a discussion between Jeff Kipnis and Reinhold Martin on agency, held at the GSD earlier this year. I know it's long, but it's definitely worth the watch. If you want a so-so canned version that's readable in 10 minutes, this is by a GSD student who was present, posted on Archinect.
Before I get into it though I'll throw something in for contrast, and that I think speaks to my last post:
"A sense of space is closely connected with purposes. Even when architecture attempts to elevate this sense beyond the realm of purposefulness, it is still simultaneously immanent in the purpose. The success of such a synthesis is the principal criterion for great architecture. Architecture inquires: how can a certain purpose become space; through which forms, which materials? All factors relate reciprocally to one another. Architectonic imagination is, according to this conception of it, the ability to articulate space purposefully. It permits purposes to become space. It constructs forms according to purposes."This is from Theo Adorno's "Functionalism Today", where he addresses the false separation of purpose-free form purposeful in Adolf Loos' distinction between ornament and functionalism.
