This is the first modern interpretation of Leibniz's comprehensive critique of Locke, the New Essays on Human Understanding. Arguing that the New Essays is controlled by the overriding purpose of refuting Locke's alleged materialism, Jolley establishes the metaphysical and theological motivation of the work on the basis of unpublished correspondence and manuscript material. He also shows the relevance of Leibniz's views to contemporary debates over innate ideas, personal identity, and natural kinds.

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)

In the fourth book of An Essay Concerning Human Understanding Locke hints that he could explain how God may have created matter exnihilo, but refrains from doing so. Leibniz, when he came upon this passage, pricked up his ears. There ensued a sequence of personal events which are not without charm and piquancy, and a sequence of philosophical events which are of some interest. In this paper we tell the tale.Locke has been discussing the view that the creation of matter (...) out of nothing is so inconceivable — it is so utterly impossible to think of how it might be done — that not even omnipotence could bring off such a feat, and matter must therefore be co-eternal with God.

Because of their vastness and rather fragmentary character, the writings of Leibniz leave the student unusually dependent on secondary literature for guidance. That the literature on Leibniz is exceptionally good is all the more reason to welcome the kind of orientation to the riches of both primary and secondary sources that this Companion aims to provide. Announcing itself as “the most accessible and comprehensive guide to Leibniz currently available” for nonspecialists and “a conspectus of recent developments in the interpretation of (...) Leibniz” for specialists, it lives up to both aspirations remarkably well. (shrink)

n 1695 John Locke published The Reasonableness of Christianity, an enquiry into the foundations of Christian belief. He did so anonymously, to avoid public involvement in the fiercely partisan religious controversies of the day. In the Reasonableness Locke considered what it was to which allChristians must assent in faith; he argued that the answer could be found by anyone for themselves in the divine revelation of Scripture alone. He maintained that the requirements of Scripture were few and simple, and therefore (...) offered a basis for tolerant agreement among all Christians, and thepromise of peace, stability, and security through toleration. This is the first critical edition of the Reasonableness: for the first time an authoritative annotated text is presented, with full information about sources, variants, amendments, and the publishing history of the work. Also provided in the editorial notes are cross-references, references to otherworks by Locke, definitions of terms, and other information conducive to an understanding of the text.Though modern interest has focused particularly on Locke's philosophy and political theory, increasing attention is being paid to his religious thought. These different strands cannot be understood properly in isolation from each other: so the broader aim of this edition is to help towards animproved understanding of his religious thought in the context of his work as a philosopher, political theorist, and exponent of religious toleration. In his editorial introduction John Higgins-Biddle investigates how Locke's ideas developed, and offers a critical assessment of the three maincontemporary and subsequent interpretations of Locke's religious thought, all of which are shown to be unsatisfactory.

Hobbes denies in Leviathan that we have an idea of God. He does think, though, that God exists, and does not even deny that we can think about God, even though he says we have no idea of God. There is, Hobbes thinks, another cognitive mechanism by means of which we can think about God. That mechanism allows us only to think a few things about God though. This constrains what Hobbes can say about our knowledge of God, and grounds (...) his belief in a fairly strong version of the thesis that God is incomprehensible. (shrink)

Descartes understood the subject matter of physics (or natural philosophy) to encompass the whole of nature, including living things. It therefore comprised not only nonvital phenomena, including those we would now denominate as physical, chemical, minerological, magnetic, and atmospheric; it also extended to the world of plants and animals, including the human animal (with the exception of those aspects of the human mind that Descartes assigned to solely to thinking substance: pure intellect and will). Descartes wrote extensively on physiology and (...) on the physiology and psychology of the senses. This chapter examines the notions of *physiology* and *psychology* in medical and natural philosophical works of Descartes' day; follows his efforts to bring physiology into his mechanistic idiom; considers the relation between physiology of the animal machine and psychological functions that yield functionally appropriate behavior; goes into his physiology and psychology of vision; and elaborates the tension in Descartes' works between his metaphysically supported micro-corpuscularism and his discussion of the animal machine as an organic unity comprising various functionally and teleologically characterized systems. The chapter draws on Descartes' works in both metaphysics and natural philosophy, including his Treatise on Man (originally published as L'Homme, 1664). (shrink)

Since the seventeenth century, mind-body dualism has undergone an evolution, both in its metaphysics and its supporting arguments. In particular, debates in seventeenth- and eighteenth-century England prepared the way for the fall of substance dualism—the view that the human mind is an immaterial substance capable of independent existence—and the rise of a much less radical property dualism. The evolution from the faltering plausibility of substance dualism to the growing appeal of property dualism depended on at least two factors. On the (...) one hand, there was an increasing recognition of the causal and ontological interdependence of mind and body. Important here was a growing appreciation of the dependence of thought and perception on complex activities in the brain. On the other hand, there was a reconceptualization of the nature of matter; no longer inert and passive, matter came to be viewed as active in its own right. The old arguments lost much of their force, opening the door to a new sort of argument. Rather than appealing to the supposed immaterial nature of mental substance and volition, arguments for dualism began to appeal to the subjective nature of conscious experience—and its inexplicable emergence from the brain—as proof of the ontological distinctiveness of conscious properties. Consequently, the nineteenth and twentieth centuries saw the ascent of a more plausible, but still very problematic, property dualism, a position that to this day enjoys significant support. (shrink)
