 One problem with this gloss on eliminativism is that it often depends upon controversial normative claims about appropriate scientific taxonomies. Many deny that, say, the highly disjunctive nature of a commonsense notion is sufficient justification for dropping it. If it was, we would eliminate the categories of memory and inference from scientific psychology. While authors like Griffiths and Machery present very sophisticated arguments involving specific details about the categories in question, most of these arguments either explicitly or tacitly make claims about the requirements of proper scientific categorization that are highly contentious in the philosophy of science (see, for example, the discussion in Machery, 2010).
