 Finally, we should address the reflexive value of the social sciences insofar as science plays the meta-theoretical and critical role of philosophy, displacing any alternative, autonomous and speculative source of insight. History of science, for instance, will require adequate classifications for the purposes of advancing correlations. In that regard, it will benefit from avoiding narrow dichotomies of classification and adopt, instead, the notion of theory – applied in economic planning – that aims at exploring all possibilities in the form of a matrix of combinations, realized and unrealized (in the tradition of encyclopedic and symbolic calculus of Llull and Leibniz). Neurath himself provided an application to the case of optics (Neurath 1916/1983 and Neurath 1944a, 42). Similarly for sociology, the search of an adequate classification of hypotheses in the first step. Notice, however, that the epistemological relativism associated with logical empiricism is not the outcome solely of such external sociological perspective or naturalistic and empirical considerations about scientific practice, but the philosophical rejection of Kant’s synthetic a priori and, as alternative to Kant’s approach to apriorism, the development of conventionalism by Carnap, Reichenbach and others inherited from Duhem, Poincaré and others concerning the exact sciences (Nemeth 2007, 283–4). Otherwise, Neurath pointed to the reflexivity of the social character of science itself and declared that sociologists argued, decided and acted in science as they themselves and others do in society. They are on the same boat with us; the boat of social sciences is just like that of the unified science and of social planning itself. This notion of social scientists, thinking up and putting in place possibilities under conditions of uncertainty, prompted Neurath’s final version of the boat analogy:
