Rougier and his Viennese colleagues hoped to demarcate a sphere of knowledge sheltered from the metaphysics inherent to any language, and by extension, to any political ideologies. For Hayek, Rougier, and Popper, the application of the methods of empirical science to social phenomena raised methodological dilemmas, which were superimposed onto diverging political orientations. While sharing the same imperative as their Viennese counterparts of demarcating a decontested language of science, neoliberal philosophers of science became skeptical of the powers of scientific method to directly shape social reform. Instead, they aspired to emulate the creative rupture they applauded in the philosophy of physics and mathematics to the doctrine of liberalism.
