This conversation to launch AA Files 78 is a chance to critically assess some categories whose meanings have shifted in the past two years of crisis. Lockdowns have challenged the dichotomy between ‘Public’ and ‘Home’ – themes discussed in this issue by Bushra Mohamed, Manijeh Verghese and Madeleine Kessler. The understanding that every ecological issue is also a social issue has forced us to rethink the relationship between ‘Environment’ and ‘Territory’, as Elisa Iturbe, Thandi Loewenson and David Burns show in their essays. More than anything, the very notion of the ‘Body’, as argued by Christina Varvia, has become the ultimate site of struggle. At this online launch event, these authors will share with AA Files editor Maria Shéhérazade Giudici their conjectures on how to rethink the vocabulary of architecture – and, with it, the way we experience and produce space.
