This paper tries to contribute to the elucidation of some intellectual conundrums and policy questions regarding scientific knowledge (SK). As for modelling, I have shown that the Solow model is independent of human agency, has rich and precise policy implications and captures some features of S(SK). As for policy I have obtained three results. First, the optimal path of scientific production can be reached through an attainable public intervention. Second, whether this public intervention ought to be implemented depends in part on the relevant period of adjustment, a rather unconventional notion. Third, the analysis of this relevant period of adjustment may help to understand the development of science. Finally and in relation to epistemology I have been able to suggest that visual representation can be very misleading and that the proliferation I have uncovered forces a reconsideration of the desideratum of science.
