It seemed plausible to most members of the Vienna Circle, the philosophical group most responsible for the rise of Logical Positivism, who also saw themselves as representatives of a scientific movement with tendencies based on the Enlightenment, to do their best to help spread and popularize the heart of their own teachings.¹ They also stood in the adult-education tradition of empirically-minded philosophers and scientists of the recently dismembered Austro-Hungarian Monarchy such as Ernst Mach, Ludwig Boltzmann, Friedrich Jodl, Wilhelm Jerusalem, and Adolf Stöhr. The leading members of the Vienna Circle decided during the l920's in a manner consistent with this earlier tradition and their own clear intentions to begin institutionalizing the adult-education half of their movement, bring more popular attention to their version of philosophical positivism, especially to its recent enrichment by Mach, Wittgenstein, and Russell.
