Holding unlimited economic freedom to be nearly as dangerous as physical violence, Karl Popper advocated “piecemeanl” economic intervention by the state. Jeremy Shearmur's recent book on Popper contends that as the philosopher aged, his views grew closer to classical liberalism than those expressed in The Open Society—consistently with what Shearmur sees as the logic of Popper's arguments.
