Kuhn talks about incommensurability. What are the two types of incommensurability? How
do these two types of incommensurability threaten objectivity?
Incommensurable is a term that refers to the lack of a common measure. This term originated in mathematics during the ancient times where it was used to mean lacking a common measure between magnitudes. Kuhn argued that science was characterized by incommensurability and gave the instance of the Newtonian paradigm not being commensurable with Cartesian and Aristotelian paradigms. Kuhn went ahead to give two types of incommensurability which are methodological and semantic incommensurability.
