This article aims to delve into the concept of taxonomic incommensurability as advocated by Thomas Kuhn from the 1980s onward. According to Kuhn, in this more local and moderate interpretation, the incommensurability between theories results from the semantic alteration of certain central terms, which he refers to as 'taxonomic categories'. He argues that these categories are holistically inter-defined, such that altering the meaning of any one term necessitates a redefinition of the others. To draw examples of such localized holism and (...) the semantic restructuring that ensues following a scientific revolution, Kuhn frequently references the physics of Aristotle and Newton. However, although he identifies these instances as significant, his treatment of them lacks depth. Consequently, this article seeks to thoroughly examine whether an in-depth analysis of these theories substantiates the thesis of taxonomic incommensurability. (shrink)
