Gary Hatfield examines theories of spatial perception from the seventeenth to the nineteenth century and provides a detailed analysis of the works of Kant and Helmholtz, who adopted opposing stances on whether central questions about spatial perception were fully amenable to natural-scientific treatment. At stake were the proper understanding of the relationships among sensation, perception, and experience, and the proper methodological framework for investigating the mental activities of judgment, understanding, and reason issues which remain at the core of philosophical psychology (...) and cognitive science.

This study presents a substantial and often radical reinterpretation of some of the central themes of Locke's thought. Professor Alexander concentrates on the Essay Concerning Human Understanding and aims to restore that to its proper historical context. In Part I he gives a clear exposition of some of the scientific theories of Robert Boyle, which, he argues, heavily influenced Locke in employing similar concepts and terminology. Against this background, he goes on in Part II to provide an account of Locke's (...) views on the external world and our knowledge of it. He shows those views to be more consistent and plausible than is generally allowed, demonstrating how they make sense and enable scientific explanations of nature. In examining the views of Locke and Boyle together, the book throws light both on the development of philosophy and the beginnings of modern science, and in particular it makes a considerable and original contribution to our understanding of Locke's philosophy.

Summary Robert Boyle did not subordinate chemistry to mechanical philosophy. He was in fact reluctant to explain chemical phenomena by having recourse to the mechanical properties of particles. For him chemistry provided a primary way of penetrating into nature. In his chemical works he employed corpuscles endowed with chemical properties as his explanans. Boyle's chemistry was corpuscular, rather than mechanical. As Boyle's views of seminal principles show, his corpuscular philosophy cannot be described as a purely mechanical theory of matter. Boyle's (...) classification of corpuscles allowed him to connect his corpuscular views of matter with chemistry. Boyle did not rule out the possibility of a classification of chemical substances based on their properties: his aim was to reform the received classification. (shrink)

'almost every branch of modern science can trace phases of its origin in his writings... in the broad field of science Boyle made a greater number and variety of discoveries than one man is ever likely to make again' - John Fulton, Boyle's bibliographer Robert Boyle (1627-91) was one of the most influential scientists and philosophers of the seventeenth century. The founder of modern chemistry, he headed the movement that turned it from an occult science into a subject well-grounded in (...) experiment, sound methodology and observation. His pioneering experiments on the properties of gases and his mechanistic theory of matter are the forerunners of the modern theories of chemical elements and atomic theory. He is best known for founding the renowned Boyle Lectures and for Boyle's Law that states that the pressure and volume of a gas are inversely proportional. A founding fellow of the Royal Society, three consecutive kings of England conversed familiarly with him. Philosophically, he wrote with sophistication on atheism, atomism, epistemology, miracles and natural laws. He influenced Berkeley, Spinoza, Henry More and especially John Locke, who relied on Boyle's theory of primary and secondary qualities in his Essay Concerning Human Understanding. Boyle's circle of correspondents included Newton, Locke, Aubrey, Oldenburg and Hartlib, and his influence on both British and European scholars was enormous. He also took a lead part in examining the relation of science to theology. This is the standard edition of Boyle's works and the only complete collection currently available. First published in 1772, it brings together his many and varied writings in one comprehensive, fully-indexed source. Covering his work in chemistry, philosophy and theology, it includes a Life of Boyle by Thomas Birch. The Thoemmes reprint of the second and best English edition features a new introduction by Peter Alexander, one of the world authorities on Boyle. --includes a Life of Boyle by Thomas Birch --features letters to and from Boyle --this rare edition is the only complete collected edition currently available and the standard text to which literature on Boyle refers --engraved frontispieces and several fold-out illustrations.

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)

Ten chapters of Locke's 1685 draft are given here, with an introduction, an index of correlating passages in the Essay and the draft, and an interpretive essay, "Locke on Active Power and the Idea of Active Power from Bodies." The passages discuss various aspects of Locke's views on power and causation, including his distinction between active and passive powers, the relation between active power and minds, passive power and bodies, the origin of the idea of power, the definition of qualities (...) as powers, the distinction between actual and potential qualities, our ignorance of the causal basis of properties, and the nature of the causal relation between inner constitutions and sensible qualities of bodies.
