The Multicriterial Approach to the Problem of Demarcation

The problem of demarcating science from nonscience remains unsolved. This article executes an analytical process of elimination of different demarcation proposals put forward since the professionalization of the philosophy of science, explaining why each of those proposals is unsatisfactory or incomplete. Then, it elaborates on how to execute an alternative multicriterial scientific demarcation project put forward by Mahner (2007, 521-522; 2013, 29-43). This project allows for the demarcation not only of science from non-science and from pseudoscience, but also of different types of sciences and of scientific fields (e.g., formal sciences, natural sciences, social sciences) from each other. This article also offers arguments in favor of accepting two types of scientific demarcations, namely epistemic-warrant scientific demarcations and territorial scientific demarcations, and argues in favor of accepting a territorially broad scientific demarcation.
