This evening I hopped on the bus to Marylebone Road to hear Pier Vittorio Aureli’s keynote lecture at Westminster University’s conference on Scarcity. The theme of the conference is, it goes without saying, timely. As PV pointed out, if the paradigm of the 20th century was growth, then its corollary in the 21st is scarcity. And yet it has only been patchily theorised. Having said that, PV’s approach to the topic was tangential and, I’m about to argue, provocative for the sake of it.
