Isaac Newton’s views on the mind–body relation are of interest not only because of their somewhat unique departure from popular early modern conceptions of mind and its relation to body, but also because of their connections with other aspects of Newton’s thought. In this paper I argue that (1) Newton accepted an interesting sort of mind–body monism, one which defies neat categorization, but which clearly departs from Cartesian substance dualism, and (2) Newton took the power by which we move our (...) bodies by thought alone to be a member of the family of forces that includes gravity and electricity. Time and again, Newton draws an analogy between the ultimate cause and nature of the volitional powers of mind and the ultimate cause and nature of these other forces. (shrink)

This paper describes the affinities between Socinian and Unitarian materialism. Based on different philosophical traditions, the Socinian Christoph Stegmann and the Unitarian Joseph Priestley developed a strong “system of materialism” which fit very well with Christian doctrines and the Bible. The conviction that the whole man is material and therefore mortal became the common basis for these radical thinkers. Stegmann formulated within the Aristotelian tradition a “non-reductive” materialism in which matter, not form, became the fundamental principle of all living things. (...) Priestley, on the other hand, created his “absolute” materialism by developing a new understanding of the concept of matter according to the philosophical rules of Isaac Newton. The paper will discuss the affinities and differences between these two different concepts of materialism. The idea of a thinking matter, most prominently formulated by John Locke, will serve as a link between them. (shrink)

The term “priestcraft” became fashionable in the 1690s. This essay explores its use among the anti-clericals in John Locke’s circle and examines the critique of priestcraft in his own Reasonableness of Christianity (1695). The commentaries and church histories, in correspondence and published treatises, of Benjamin Furly, William Popple, Damaris Masham, William Stephens, and Sir Robert Howard are examined. The Lockean circle remained committed to Christian revelation and, for the most part, to a reformed Church of England, and it is argued (...) that it is a mistake to identify the critique of priestcraft exclusively with deism and the subversion of Christianity. The polemical critique of the priestly deformations of Christianity, though often scabrously hostile to clergies, served equally the ecclesiastical and political causes of post-Revolution latitudinarian Anglicanism. The Lockean circle was committed to constructing a Church Whig ecclesiology. (shrink)

In this paper I consider a cluster of positions which depart from the immortalist and dualist anthropologies of Rene Descartes and Henry More. In particular, I argue that John Locke and Isaac Newton are attracted to a monistic mind-body metaphysics, which while resisting neat characterization, occupies a conceptual space distinct from the dualism of the immortalists, on the one hand, and thoroughgoing materialism of Thomas Hobbes, on the other. They propound a sort of property monism: mind and body are distinct, (...) with distinct characteristics and functions, but are, nevertheless, ontologically interdependent. Consciousness ? the locus of personhood, and thus, a necessary condition for personal immortality ? is an embodied phenomenon; its preservation requires the life and proper functioning of the body. Dying with the dissolution of his body, then, man is a compound wholly mortal. Nevertheless, both Locke and Newton accepted the possibility of personal immortality; with Hobbes, both looked to the Biblical promise of bodily resurrection. For with the re-vitalization of the body ? and a subsequent restoration of consciousness and memory ? personal identity is preserved, even beyond the grave. (shrink)

Locke’s consciousness-based theory of personal identity resulted not only from his agnosticism on substance, but also from his biblical theology. This theory was intended to complement and sustain Locke’s moral and theological commitments to a system of otherworldly rewards and sanctions as revealed in Scripture. Moreover, he inferred mortalist ideas from the Bible, rejecting the resurrection of the same body and maintaining that the soul dies at physical death and will be resurrected by divine miracle. Accordingly, personal identity is neither (...) in the soul, nor in the body, nor in a union of soul and body. To Locke, personal identity is in consciousness, which, extending “backwards to any past Action or Thought,” enables the self, both in this life and upon resurrection for the Last Judgment, to recognize that “it is the same self now it was then; and ‘tis by the same self with this present one that now reflects on it, that that Action was done” (Essay II.xxvii.9).

This paper considers three accounts of the relationship between personal immortality and materialism. In particular, the pagan mortalism of the Epicureans is compared with the Christian mortalism of Thomas Hobbes and John Locke. It is argued 1) that there are significant similarities between these views, 2) that Locke and Hobbes were, to some extent, influenced by the Epicureans, and 3) that the relation between mortality and materialism is not as straightforward as is commonly supposed.
