Jeffrey Kipnis and Marrikka Trotter debate the role of history and theory at SCI-Arc, and in the discipline of architecture. Kipnis is doubtful, but Trotter argues that history and theory can expose “unbound points,” i.e. possibilities that hadn’t yet been taken up. Their conversation touches on a range of topics, including, currency, Eyal Weitzman’s “forensic architecture,” alternative models of architectural history by John Harwood and Reinhold Martin, and Black Box algorithms.
