Thomas Reid often seems distant from other Scottish Enlightenment figures. While Hume, Hutcheson, Kames, and Smith wrestled with the nature of social progress, Reid was busy with natural philosophy and epistemology, stubbornly loyal to traditional religion and ethics, and out of touch with the heart of his own intellectual world. Or was he? I contend that Reid not only engaged the Scottish Enlightenment's concern for improvement, but, as a leading interpreter of Isaac Newton and Francis Bacon, he also developed a scheme to explain the progress of human knowledge. Pulling thoughts from across Reid's corpus, I identify four key features that Reid uses to distinguish mature sciences from prescientific arts and inquiries. Then, I compare and contrast this scheme with that of Thomas Kuhn in order to highlight the plausibility and originality of Reid's work.

Abstract After a brief introduction, this “symposium” presents four essay reviews of three recent major studies of Newton’s life and works beyond the mathematics, physics and natural philosophy for which he is principally known: Jed Buchwald’s and Mordechai Feingold’s Newton and the Origin of Civilization (2013), Rob Iliffe’s Priest of Nature: The Religious Worlds of Isaac Newton (2017), and William R. Newman’s Newton the Alchemist (2019); and they address Newton’s work on history, chronology, theology and alchemy. The four reviewers are leading Newton scholars in their own right, and assess how these three studies advance our understanding of Newton the “scientist”, as well as Newton the man in his times. Niccolò Guicciardini considers their relevance to our understanding of Newton’s mathematics; Scott Mandelbrote assesses how they advance our understanding of Newton’s local and historical context; Steffen Ducheyne focuses on what we can learn about Newton’s methodological concerns and working practices; while Stephen Snobelen considers how these studies can help us understand the place of religion in Newton’s life and work. We conclude with responses from each of the reviewed authors: Feingold (representing also his co-author Jed Buchwald), Iliffe, and Newman. New insights into key questions are afforded throughout. Should Newton’s work in these different areas be considered continuous with his more “scientific” works, or compartmentalized according to his rigorous disciplinary procedures?

Isaac Newton had a vexed relationship with his most important immediate predecessor in mathematics and philosophy, René Descartes. He was typically loath to admit the importance of Cartesian ideas for the development of his own thinking in mathematics and natural philosophy. For this reason, generations of students and scholars relying on Newton’s published work had little inkling of Descartes’s significance. This unfortunate fact was compounded by the tendency of philosophers to focus on the Meditations or the Regulae in their scholarship, for it was Descartes’s Principles above all that influenced Newton’s thinking as a young man. With the discovery of a previously unpublished manuscript amongst Newton’s papers by two famous historians of science in the middle of the twentieth century, everything changed. The manuscript, now known as De Gravitatione after its first line, illustrates the astonishing care with which Newton read the Principles, focusing his critical acumen on Descartes’s understanding of space, time, and motion. These criticisms of Descartes, in turn, shine light on otherwise opaque passages in Newton’s most significant published discussion of space, time, and motion, the Scholium in Principia mathematica. Indeed, the very title of the latter work represents both an homage to, and a swipe at, Descartes’s work: Newton would offer mathematical principles of natural philosophy to replace Descartes’s qualitative account. It is not a stretch to say that Newton saw further because he stood on Descartes’s shoulders, even if he wouldn’t admit it publicly.

Cambridge Platonism was an intellectual movement broadly inspired by the Platonic tradition, centred in Cambridge from the 1630s to the 1680s. Its hallmark was a devotion to reason in metaphysics, religion and ethics. The Cambridge Platonists made reason rather than tradition and inspiration their ultimate criterion of knowledge. Their central aim was to reconcile the realms of reason and faith, the new natural philosophy and Christian revelation. Although loyal to the methods and naturalism of the new sciences, they opposed its mechanical model of explanation because it seemed to leave no room for spirit, God and life. In epistemology the Cambridge Platonists were critics of empiricism and stressed the role of reason in knowledge; they also criticized conventionalism and held that there are essential or natural distinctions between things. In metaphysics they attempted to establish the existence of spirit, God and life in a manner consistent with the naturalism and method of the new sciences. And in ethics the Cambridge Platonists defended moral realism and freedom of the will against the voluntarism and determinism of Hobbes and Calvin. Cambridge Platonism was profoundly influential in the seventeenth and eighteenth centuries. It was the inspiration behind latitudinarianism and ethical rationalism, and many of its ideas were developed by Samuel Clarke, Isaac Newton and the Third Earl of Shaftesbury.


This chapter presents George Boole's lecture on the discoveries of Sir Isaac Newton. The first subject of importance that engaged Newton's attention was the phenomena of prismatic colors. The results of his inquiries were communicated to the Royal Society in the year 1675, and afterwards published with most important additions in 1704. The production was entitled “Optics; or, a Treatise on the Reflections, Refractions, Inflections, and Colours of Light.” It is considered one of the most elaborate and original of his works, and carries on every page the traces of a powerful and comprehensive mind. Newton also discovered universal gravitation, which was announced to the world in 1687 through the publication of the “Principia, or Mathematical Principles of Natural Philosophy.” The object of the “Principia” is twofold: to demonstrate the law of planetary influence, and to apply that law to the purposes of calculation.

When we consider the extraordinary advancement in natural philosophy, from the surprising discoveries of the great Sir Isaac Newton, and other ingenious men, who have followed his example; it may afford matter of the greatest wonder, to find the most acute philosophers still contending, whether the force of percussion be in proportion to the velocity of bodies in motion, or the squares of those velocities.

Will Ladislaw's words, which so disillusion the young Dorothea, might also depress the modern interpreter of Newton's theology. Encountering the bulk of Newton's manuscript theology, it is tempting to sympathize with Dorothea's eventual response to The Key to all Mythologies, and to want nothing of it. The assessment of John Conduitt, Newton's son-in-law and executor, that his ‘relief and amusement was going to some other study, as history, chronology, divinity, and chemistry’ has in the past provided an ample excuse for those who have wished to take such a course, and to ignore Newton's biblical criticism. In the last three decades, however, Newton scholarship has come to terms with its hero's twilight activities, and reclassified them as being at least as important to him as the natural philosophy of the Principia, and intimately bound up with the thinking behind that philosophy. But although many modern scholars are now reluctant to see Newton as Stephen Hawking in breeches, historians of science have tended to concentrate on the implications for Newton's philosophy of his religious and alchemical writings, and in the process often have distorted their religious context. Historians of ideas have been beguiled by Newton's disciples, and by the esoteric texts from Newton's library, to ride hobbyhorses of their own which do not always illuminate Newton's reasons for writing theology. There is a danger of ‘knowing what is being done by the rest of the world’ before troubling with what Newton was up to when he worried about religion and theology, channelling his energies into treatise after treatise on the interpretation of prophecy. I want to suggest what some of Newton's concerns may have been, by looking at his ideas of religious duty and of the Church, and to liberate Newton from his disciples for long enough to consider some of his ideas about the relationships of prophetic and natural philosophical explorations of divinity.
