 Neurath enjoyed early attention and recognition for his logic work also reflected in early reminiscences of figures such as Popper and the mathematician Karl Menger. Perhaps now surprisingly, mentions of Neurath’s and Olga Hahn’s papers, including a joint one, were included by the logicians C.I. Lewis, in 1918, and Alonzo Church, in 1936, in their canonical bibliographies on symbolic logic (Lewis 1918 and Church 1936).Neurath kept algebraic logic and its symbolic dimension as a recurrent standard and resource, first in his earlier work on the social sciences and pictorial language, and subsequently in related contributions to the discussions that informed logical empiricism (for a detailed discussion, see Cat 2019). The relevance to his interest in political economy concerned the rational and scientific character of economic theory, the possibility of qualitative measurement and the limits of quantification and univocal determination, and, as a result, also of decision-making and prediction. Contrary to predominant accounts using attention to formal languages and logic to pit against each other wings and members of the logical empiricist movement, the symbolic logical standard may be considered a unifying framework that distinguished Neurath with it and not from it. It a unifying reference he willingly adopted when he coined the term ’logical empiricism’ (Mormann 1999 and Cat 2019). The differentiating role in Neurath’s positions can be identified in his shifting and progressively skeptical and critical attention to the standard and the his attention to algebraic logic rather than the newer logic familiar to Carnap at work in Frege and Russell’s logicism.
