 Of course, this view has been challenged recently. Allison Kuklok (2018) argues that this watch passage does not show that Locke took our sorting practices (at either the phenomenal or microphysical level) to be arbitrary. For her, a mistake that interpreters of Locke make is to claim that the watch passage asserts that there is no fact of the matter about how things should be classified, and therefore, our classifications are arbitrary. According to Kuklok, this watch analogy is intended to show the irrelevance of hidden internal differences to species whose boundaries are antecedently drawn at the phenomenal level by our natural sorting practices. By her lights, once we acknowledge that passages like the watch analogy do not concern classification, we see that Locke never argued that classification is arbitrary.
