When he died in 2012, David Fleming -- a polymath thinker among the earliest to address Peak Oil -- left behind an unusual book manuscript about climate change, the fragility of capitalism, and the likely nature of our post-capitalist future. Fortunately, Shaun Chamberlin, a British author and activist who was Fleming's associate, shepherded the manuscript to publication as 'Lean Logic: A Dictionary for the Future and How to Survive It' and a companion volume, 'Surviving the Future.' In this podcast, Chamberlin reflects on Fleming's brilliant, visionary writings and his own ongoing activism and initiatives.
