 This engineering value of unity applied equally to political governance and scientific action, since both are collective and pragmatic endeavors. According to Neurath, ‘scientific theories are sociological events’ (Neurath 1932a/1983, 88), and, since ‘our thinking is a tool’, in this case the ‘modern scientific world-conception’ aims to ‘create a unified science that can successfully serve all transforming activity’ (Neurath 1930/1983, 42). In both cases, Neurath noted, ‘common planned action is possible only if the participants make common predictions’ and group predictions yield more reliable results; therefore, he concluded, ‘common action presses us toward unified science’ (Neurath 1931/1973, 407). Indeed, all along, for Neurath scientific attitude and solidarity (and socialism) go together (Neurath 1928/1973, 252).
