While the tradition of Locke scholarship holds that both Locke and Boyle are species anti-realists, there is evidence that this interpretation is false. Specifically, there has been some recent work on Boyle showing that he is, unlike Locke, a species realist. In this paper I argue that once we see Boyle as a realist about natural species, it is plausible to read some of Locke’s most formidable anti-realist arguments as directed specifically at Boyle’s account of natural species. This is a (...) break from the tradition because no one in the literature has yet suggested that some of Locke’s arguments in Book III of the Essay include a criticism of Boyle’s doctrine of species. Moreover, identifying Boyle as Locke’s intended target illuminates some of the more vexing passages in the Essay concerning real essences. (shrink)

In his “Méthode nouvelle,” an anonymous article in the Bibliothèque universelle of 1686, John Locke described his way of collecting excerpts in notebooks and retrieving relevant entries. The well‐known practice of entering textual passages in commonplace books sits uneasily with Locke's criticism of received opinion and authority. Is it possible that he used any of these notes to think with? I suggest that the conditions for this were provided by Locke's interactions with some of his notes, including those which recorded (...) observations, testimonies and experiments. As well as labelling excerpts and other notes with topical Titles, Locke sometimes added precise bibliographical citations, transferred material across notebooks, interpolated his own signed reflections and queries, and (eventually) dated entries.
