'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 magnet served three interests of Restoration mechanical philosophers: it provided a model of cosmic forces, it suggested a solution to the problem of longitude determination, and evidence of its corpuscular mechanism would silence critics. An implicit condition of William Gilbert's ‘magnetic philosophy’ was the existence of a unique, immaterial magnetic virtue. Restoration mechanical philosophers, while claiming descent from their compatriot, worked successfully to disprove this, following an experimental regime of Henry Power. Magnetic philosophy lost its coherence and became subsumed (...) in the study of effluvia. This contradiction of a distinct, yet mechanical magnetic philosophy came to a head in 1684 in an argument between Robert Hooke and Martin Lister. An effluvial explanation of magnetism introduced great complexity to the North-seeking behaviour of compass needles, and undermined the already troubled longitude programme. Thus magnetic philosophy no longer furthered the interests which had maintained it, and it was abandoned. (shrink)

The ArgumentRecent historiography of the Scientific Revolution has challenged the assumption that the achievements of seventeenth-century natural philosophy can easily be described as the ‘mechanization of the world-picture.’ That assumption licensed a story which took mechanization as self-evidently progressive and so in no need of further historical analysis. The clock-work world was triumphant and inevitably so. However, a close examination of one key group of natural philosophers working in England during the 1670s shows that their program necessarily incorporated souls and (...) spirits, attractions and congruities, within both their ontology and their epistemology. Any natural philosophical strategy which excluded spirits and sympathies from its world was condemned as tending to subversion and irreligion. This examination shows that the term ‘mechanical philosophy’ was a category given its meanings within local contexts and carries no universal sense separate from that accomplished by these natural philosophers. It also shows how the experimental praxis was compelled to treat souls and spirits, to produce them through experimental labor, and then to extend these experimentally developed entities throughout the cosmos, both social and natural. The development of mechanical philosophy cannot be used to explain the cognitive and social structure of this program, nor its success: instead, the historical setting of experimental work shows how a philosophy of matter and spirit was deliberately constructed by the end of the seventeenth century.

The work of Robert Hooke on acoustics and music theory is a larger subject than might seem the case from studies of his career so far available. First, there are his experiments for the Royal Society which can be defined as purely acoustical, which anticipate later experiments performed by men such as J. Sauveur and E. Chladni. Second, there are passages in many of his writings which by extensive use of musical analogy attempt to account for all physical phenomena of (...) the universe, which operates on the principles of ‘harmony’ and ‘dissonance’. It is in this context that the hitherto unpublished manuscript presented at the end of this paper should be considered. This essay, which combines both the older tradition of the ‘praise of music’ and the newer consideration of the physical nature of musical sound, illustrates a particular aspect of Hooke's thought which exercised a profound influence on all his studies.
