"On June 22, 1936, the philosopher Moritz Schlick was on his way to deliver a lecture at the University of Vienna when Johann Nelböck, a deranged former student of Schlick's, shot him dead on the university steps. Some Austrian newspapers defended the madman, while Nelböck argued in court that his onetime teacher had promoted a treacherous Jewish philosophy. Weaving an enthralling narrative set against the backdrop of rising extremism in Hitler's Europe, David Edmonds traces the rise and fall of the Vienna Circle--associated with billiant thinkers like Otto Neurath, Kurt Gödel, Rudolf Carnap, Ludwig Wittgenstein, and Karl Popper--and of a philosophical movement movement that sought to do away with metaphysics and pseudoscience in a city darkened by and unreason."--
