I was sad to hear that David Slater has passed away. In a parallel universe, we would have been colleagues, if only the University I worked for way back when had had the intelligence to hire David when they had the chance. I have always found him to be one of the most compelling critical thinkers in and around geography. He is among the few people to have written thoughtfully about the geographical resonances of democratic theory. His argument about ‘learning from other regions‘ was both a crucial moment in the reception of postcolonial thought in human geography, and remains highly relevant in the context of current debates about southern theory and decoloniality. The very first thing I ever read by him, when I was an undergraduate, on economism in development theory, remains in my memory as one of the smartest things I have ever read, a model of critical analysis, unashamed of its theoretical sophistication, to which we perhaps should all aspire.
