The relationship between John Locke and Isaac Newton, his co-founder of, in the apt phrase of one recent writer, ‘the Moderate Enlightenment’ of the eighteenth century, has many dimensions. There is their friendship, which began only after each had written his major work, and which had its stormy interlude. There is the difficult question of their mutual impact. In what ways did each draw intellectually on the other? That there was some debt of each to the other is almost certain, (...) but its exact extent is problematic. Questions may be asked over a whole range of intellectual issues, but not always answered. Thus their theology, which was in many respects close, and which forms the bulk of their surviving correspondence, may yet reveal mutual influence. There is the question of their political views, where both were firmly Whig. But it is upon their philosophy, and certain aspects of their philosophy in particular, that this paper will concentrate. My main theme is the nature of their empiricism, and my main contention is that between them they produced a powerful and comprehensive philosophy. (shrink)

Some scholars suggest that John Locke’s revisions to the chapter “Of Power” for the 1694 second edition of his Essay concerning Human Understanding may be indebted to the Cambridge Platonist, Ralph Cudworth. Their claims rest on evidence that Locke may have had access to Cudworth’s unpublished manuscript treatises on free will. In this paper, I examine an alternative suggestion – the claim that Cudworth’s daughter, Damaris Cudworth Masham, and not Cudworth himself, may have exerted an influence on Locke’s revisions. I (...) discuss the plausibility of this claim in light of the relevant historical and textual evidence. (shrink)

In this paper, I consider Isaac Newton’s fevered accusation that John Locke is a ‘Hobbist.’ I suggest a number of ways in which Locke’s account of the mind–body relation could plausibly be construed as Hobbesian. Whereas Newton conceives of the human mind as an immaterial substance and venerates it as a finite image of the Divine Mind, I argue that Locke utterly deflates the religious, ethical, and metaphysical significance of an immaterial soul. Even stronger, I contend that there is good (...) reason to suspect that Locke is a crypto-materialist, at least with respect to human beings, and in this respect, could reasonably be labeled a ‘Hobbist.’.

This thesis provides a new analysis of early contributions to the development of the theory of absolute time—the notion that time exists independently of the presence or actions of material bodies and has no material cause. Though popularly attributed to Newton, I argue that this conception of time first appeared in medieval philosophy, as a solution to a peculiar theological problem generated by a widespread misrepresentation of Aristotle. I trace the subsequent evolution of the theory of absolute time through to (...) the seventeenth-century, and argue that Newton, if anything, retreats from a full endorsement of the doctrine. (shrink)
