If you want to know what society looks like, look at our cities, look at their distribution of spaces, their scales, their densities. Look at how cities curate events. This article sketches the basis for architectural thinking on individual/collective social formations as read through the texts of Vitruvius and Freud with support from Aristotle, Arendt, and Lacan, in parallel with city projects by the rooms+cities studio, a Master’s-level design research unit at the University of Dundee, which is itself a collective project that begins with the close reading of canonic city plans in search of the collective body of knowledge that comprises the discipline and practice of architecture. Teaching may not be the only way to change built environment thinking but it is one way. Vittorio Gregotti reckoned that the schools were best placed to challenge establishment practices with avantgarde thought. We use architecture to think the relation between the individual and the collective, and thereby to make a space for politics and public life. This article is thus comprised of two arguments, one predominantly textual, the other graphic, of complementary weight and importance, that run side by side and occasionally cross or mingle.
