FROM LOCKE TO MATERIALISM: EMPIRICISM, THE BRAIN AND THE STIRRINGS OF ONTOLOGY Charles T. Wolfe Centre for History of Science, Department of Philosophy and Moral Sciences Ghent University Associate, Unit for History and Philosophy of Science University of Sydney
[email protected] For a volume on 18th-Century Empiricism and the Sciences edited by A.-L. Rey and S. Bodenmann Dordrecht: Springer Abstract My topic is the materialist appropriation of empiricism – as conveyed in the ‘minimal credo’ nihil est in intellectu quod non fuerit in sensu (which is not just a phrase repeated from Hobbes and Locke to Diderot, but significantly, is also a medical phrase used by Harvey, Mandeville and others). That is, canonical empiricists like Locke go out of their way to state that their project to investigate and articulate the ‘logic of ideas’ is not a scientific project: “I shall not at present meddle with the Physical consideration of the Mind” (Locke 1975, I.i.2), which Kant gets exactly wrong in his reading of Locke, in the Preface to the A edition of the first Critique. Indeed, I have suggested elsewhere, contrary to a prevalent reading of Locke, that the Essay is not the extension to the study of the mind of natural-philosophical methods; that he is actually not the “underlabourer” of Newton and Boyle he claims politely to be in the Epistle to the Reader (Wolfe and Salter 2009, Wolfe 2010). Rather, Locke says quite directly, “Our Business here is not to know all things, but those which concern our Conduct” (Locke 1975, I.i.6).
