Since the early 1930s, a broad acceptance of the need for social planning had been growing in Britain. Neurath naturally became involved in debates on this matter, not only with British and American scholars (C. H. Waddington and James Burnham) but with fellow Central European émigrés in the UK, Karl Mannheim and Friedrich Hayek. Neurath and Mannheim concurred on the possibility of ‘planning for freedom’, whereas Hayek feared that any socialist planning would lead inevitably to totalitarianism. Neurath took issue with this, not least in his reading of Hayek’s The Road to Serfdom, which can be reconstructed from Neurath’s copious notes in his own copy. Neurath’s ideas of the 1920s for a socialized ‘economy in kind’ were moderated by his situation in Britain, with its democratic ‘muddle’ of the 1940s. By contextualizing Neurath’s views in relation to other prominent figures of the era, we point out what made him unique among them.
