 Feyerabend, like Kuhn, explicitly drew from Wolfgang Köhler’s work in Gestalt psychology in the development of his notion of incommensurability. Moreover, Köhler had already applied the notion of incommensurability to scientific theories (see Section 2.2.2). Köhler’s use applies to different areas within natural science, not to successive scientific theories such as in early Kuhn (1962). Köhler’s use of the term ‘incommensurable’ to describe the relationship between the concepts of psychology and physics was a main source of Feyerabend’s development of the idea of the incommensurability (Oberheim 2005). Feyerabend’s discussion of incommensurability in the formulation of the mind-body problem derives directly from Köhler’s claims (Oberheim 2005). However, Feyerabend’s (Wittgensteinian) strategy for overcoming the incommensurability in the dissolution of philosophical conundrums is not Köhler’s (Oberheim 2006, 43–45). Feyerabend suggested that the insolubility is due to the unwillingness of philosophers of different persuasions to change the deeply entrenched meanings of their terms, and that in this case, the mental should be reinterpreted so that it is compatible with materialism (Feyerabend 1963b).
