 Neurath’s philosophical contributions to logical empiricism appear now more distinctly motivated and more clearly understood: It is to serve the valuable goal of unified science, within science, philosophy and society, that Neurath conceived the stress on two further epistemological aims, namely, the role of collective efforts and finally, by implication, intersubjectivity (ibid.). The argument from holism would in turn meet the requirements of the demarcation against metaphysics, since metaphysical terms and metaphysicians divide, whereas scientific terms and scientists unite. The boat images further illustrated Neurath’s aim of unity, within its proper epistemological framework: as a historically situated, non-foundational and collective enterprise. Science is a model and a resource for society and society is in turn a model and resource for science.
