 Finally, there is one central, substantive point of agreement between Kuhn and Feyerabend. Both see incommensurability as precluding the possibility of interpreting scientific development as an approximation to truth (or as an “increase of verisimilitude”) (Feyerabend, 1965c, 107; 1970, 220, 222, 227–228; 1975, 30, 284; 1978, 68; Kuhn 1970, 206; 2000 [1991], 95; 2000 [1993], 243ff.; cf. Oberheim 2006, 180ff.; Hoyningen-Huene 1993, 262-264). They reject such characterizations of scientific progress because they recognize and emphasize that scientific revolutions result in changes in ontology. Such changes are not just refinements of, or additions to, the older ontology, such that these developments could be seen as cumulative additions to already established theoretical views. Rather, the new ontology replaces its predecessor. Consequently, neither Kuhn nor Feyerabend can correctly be characterized as scientific realists who believe that science makes progress toward the truth.
