 Additionally, those that take an epistemology first approach are critical of metaphysical accounts of natural kinds which are overly prescriptive and homogeneous about what counts as a natural kind. The consequence of taking a metaphysics first approach is that many of the important and heterogeneous practices of kinding that are used in the context of scientific practice do not count as natural kind classifications in the metaphysical sense. The implication here is that an epistemology first approach is more consistent with a descriptive and naturalistic account of classification. Epistemological accounts of natural kinds must come first and our metaphysical accounts must be informed by these epistemological considerations.
