Isaac Newton — lived in a philosophically tumultuous time. Indeed, he helped to develop many of those methods. Leibniz of what we now call the calculus—and to what is now called physics, sir isaac newton essay, including both its experimental and theoretical aspects, will forever dominate discussions of his lasting influence. His engagement with Cartesian ideas and methods early in his life was just as significant to the transformation of philosophy in the seventeenth century as his debates with Leibniz were to the setting of the agenda of philosophy in the eighteenth.
Obviously, Newton is not part of the traditional philosophy canon of the period, sir isaac newton essay. That fact reflects an anachronistic approach to the history of modern philosophy that we have inherited from French and German scholars of the sir isaac newton essay century. Recent scholarship has challenged this conception of the canon.
Moreover, Newton engaged with, or influenced, many of the standardly canonical philosophers of the early modern era, including Descartes, Locke, Berkeley, Hume, Leibniz and Kant. His influence on early modern philosophy is a rich topic. Traditionally, sir isaac newton essay, Newton would be characterized as a mathematician for his work on the calculus and as a scientist for his work in physics.
His celebrated talent in mathematics is perhaps equaled not only by his profound theorizing concerning the physical world, but also his influential experimental methods. Indeed, Newton is remarkable for the fact that his work as a theoretician is matched by his work as an experimentalist—either aspect of his oeuvre would be sufficient to secure his place in the history of modern science, sir isaac newton essay.
So in the popular imagination, and in the history books, Newton is seen as one of the greatest scientists of the modern period, on a par with few others perhaps Darwin or Einstein, sir isaac newton essay. This view will continue to dominate our understanding of Newton in the twenty-first century. When Newton published his principal works, he was not contributing to a well-established field, he was helping to create modern mathematical physics.
This meant that few of his ideas, methods, or approaches, whether in mathematics or sir isaac newton essay experimental physics, could be taken for granted, sir isaac newton essay. This frequently upset Newton, who had a famous, lifelong aversion to intellectual debate and controversy. But the intense controversies produced by his mathematical, empirical and philosophical methods and ideas continually prompted him to broach philosophical topics Janiak As a result, he was widely considered a leading philosopher throughout the Enlightenment.
In this case, however, the evolution of the English language tracks a substantive intellectual development. As a matter of historical fact, sir isaac newton essay, the category of the scientist—along with that word in English—is a nineteenth-century invention.
Descartes had famously promised that his physics required nothing more than the principles of geometry and pure mathematics PrinciplesPart Two, § Although Descartes was a great sir isaac newton essay, the author of a major work in geometry inNewton thought nonetheless that he had not lived up to this promise, so he would assuredly introduce mathematical principles for natural philosophy.
It is therefore more historically accurate and more illuminating to interpret Newton within the historical stream of natural philosophy. Philosophers studying nature were often actually studying texts—such as commentaries on Aristotle—rather than conducting experiments or engaging in observations, and they often did not employ mathematical techniques.
Traditionally, natural philosophy in Aristotelian circles was not conceived of as a mathematical discipline unlike, say, optics or astronomy ; instead, it focused especially on the natures of objects and on causation. In the seventeenth century, natural philosophers like Galileo, Boyle, Descartes, and Newton began to reject not only the doctrines of the Aristotelians, but their techniques as well, developing a number of new mathematical, conceptual and experimental methods.
Of course, these developments have often been regarded as central to the Scientific Revolution. Despite the centrality of these changes during the seventeenth century, however, the scope of natural philosophy had not dramatically changed. Natural philosophers like Newton expended considerable energy trying to understand, e. Newton was a natural philosopher—unlike Descartes, he was not a founder of modern philosophy, for he never wrote a treatise of the order of the Meditations, sir isaac newton essay.
Nonetheless, his influence on philosophy in the eighteenth century was profound, extending well beyond the bounds of philosophers studying nature, encompassing numerous figures and traditions in Britain, on the Continent, sir isaac newton essay, and even in the New World. Newton himself approached the topic more cautiously.
For his part, Hume interpreted Newtonian natural philosophy in an empiricist vein and noted some of its broader implications in his Treatise of Human Nature and Enquiry Concerning Human Understanding Propositions deduced from axioms in Euclidean geometry were seen as paradigm cases of knowledge. Indeed, if we resist the temptation to understand Newton as working within a well established discipline called mathematical physics, if we see him instead as a philosopher studying nature, his achievement is far more impressive, for instead of contributing to sir isaac newton essay well-founded field of physics, he had to begin a process that would eventually lead aspects of natural philosophy to be transformed into a new field of study.
This transformation took many decades, involving a series of methodological and foundational debates about the proper means for obtaining knowledge about nature and its processes. Newton himself not only engaged in these debates from his very first publication in optics inbut his work in both optics and in the Principia generated some of the most significant methodological discussions and controversies in the late seventeenth and early eighteenth centuries.
These debates concerned such topics as the proper use of hypotheses, the nature of space and time, the best understanding of the forces of nature, and the appropriate rules for conducting research in natural philosophy. Those debates focused on numerous substantive sir isaac newton essay, but also included extensive discussions of the proper methodology in natural philosophy.
Similarly, any discussion of the role of hypotheses in philosophical reasoning would mention Newton prominently. Newton consistently regarded these figures not merely as disagreeing with his views, but as misinterpreting them. Secondly, because Newton regarded himself as having been deeply misinterpreted by his critics, he had recourse to meta-level or methodological discussions of the practice of optics and of the kinds of knowledge that philosophers can obtain when engaging in experiments with light.
The field of optics has its origins in the Ancient Greek period, when figures like Euclid and Ptolemy wrote works on the subject, but they often focused primarily on the science of vision, analyzing e. the visual rays that were sometimes thought to extrude from the eye, enabling it to perceive distant physical objects. In the early modern period, Kepler and Descartes each made fundamental contributions to the field, including the discovery of the inversion of the retinal image in the former case and an explanation of refraction in the latter case.
The paper recounts a number of experiments that Newton says he had conducted several years earlier. But what precisely counts as a feature of light? Both Hooke and Huygens were wave theorists. This question obviously continued to have relevance into the twentieth century, when wave-particle duality was discovered.
In his experiments with the prism, however, Newton apparently sought to investigate something else, viz. These things being so, it can be no longer disputed, whether there be colours in the dark, nor whether they be the qualities of the objects we see, no nor perhaps, whether Light be a Body. For, since Colours are the qualities of Light, having its Rays for their entire and immediate subject, how can we think those Rays qualities also, unless one quality may be the subject of and sustain another; which in effect is to call it substance.
We should not know Bodies for substances, were it not for their sensible qualities, sir isaac newton essay, and the Principal of those being now found due to something else, we have as good reason to believe that to be a substance also. Newton —, vol. Newton seems here to be arguing as follows: since rays of light have colors as basic features, we should regard these colors as qualities or properties of the rays despite the fact that these properties are imperceptible under any ordinary circumstance ; but doing so requires us to think of the rays as bearers of qualities, which is to say, as substances in sir isaac newton essay own right.
And if rays of light are substances, this means that we cannot also think of them as qualities or properties of anything else.
This last point follows from a widely accepted notion of a substance at the time, one easily found in Descartes [ 7 ]viz. And if we cannot think of rays of light as properties or qualities, then they are not waves, for waves are features of some medium—think of waves on the surface of a lake. These are apt to strike us as canonical philosophical problems.
Among philosophers, he was not alone. He insisted to friends and colleagues that he found intellectual controversy unbearable.
But he never followed through with his threat to disengage from discussions in natural philosophy, sending many important letters throughout his long intellectual career. Like many philosophers who worked in the wake of Galileo and of Descartes, it seems that Newton never extensively analyzed Aristotelian ideas about nature. He would have encountered such ideas in the curriculum at Trinity College, but there is not much evidence that he took them seriously.
Some of that evidence comes from a manuscript that was first transcribed and published in by the great historians of science, Marie Boas Hall and A, sir isaac newton essay. Rupert Hall. First and foremost, the manuscript lacks a date, and there is no scholarly consensus regarding its precise provenance, sir isaac newton essay. Despite these facts, the text contains a treasure trove of arguments concerning Cartesian ideas. For instance, it dispels the easily formed impression that Newton sought, in sir isaac newton essay Principiato sir isaac newton essay a Leibnizian conception of space and time, as his defender, Samuel Clarke, would attempt to do years later in the correspondence of —16 discussed below.
Newton took special interest in the Cartesian view of space sir isaac newton essay body, and in related views concerning the causal relations between minds and bodies and between God and the bodies that constitute the natural world. Beginning with his correspondence with Descartes in Lewissir isaac newton essay, and continuing with a series of publications in later years, many of which Newton owned in his personal library HarrisonMore argued that Descartes made two fundamental mistakes: first, he wrongly contended that extension and matter are identical and that the world is therefore a plenum ; and second, he mistakenly believed that God and the mind were not extended substances, which made their causal interactions with such substances mysterious.
Just as Princess Elisabeth of Bohemia had raised fundamental objections to Cartesian dualism see Shapiro in the early s, More raised similar objections against the Cartesian view of the divine a few years later Lewis For how could God part the Red Sea, suggested More, unless God were present precisely where the Red Sea is located? Of course, More agreed that God is not made of parts, sir isaac newton essay, cannot be imagined, and cannot be affected by the causal activity of material bodies—the causal arrow flows only in one direction.
But More concluded that God is extended in his own way. In a number of texts, including De Gravitationethe famous discussion of space and time in the Scholium to the Principiaand the discussion of God in the General Scholium, Newton made his generally Morean attitudes perfectly clear. He rejected the Cartesian identification of extension and matter, arguing that space itself exists independently of material objects and their relationsand he contended that all entities, including the human mind and even the divine being, are extended in the sense that they have spatial location, even if they are sir isaac newton essay in ways that distinguish them from ordinary material bodies.
As Newton puts it in a famous passage from De Gravitatione :. Space is an affection of a being just as a being.
No being exists or can exist which is not related to space in some way. God is every where, created minds are somewhere, and body is in the space that it occupies; and whatever is neither everywhere nor anywhere does not exist. And hence it follows that space is an emanative effect of the first existing being, for if any being whatsoever is posited, space is posited.
Newton Space is a fundamental concept in part because Newton not only conceives of it as independent of objects and their relations, but because he argues that every entity must somehow connect with space in some way. Newton does not shy away from making sir isaac newton essay conception of the divine explicit in his public writings, despite the fact that it was anathema to his Cartesian and Leibnizian contemporaries. In the General Scholium to the Principiawhich was added to the second edition of the text sir isaac newton essayfor instance, he famously writes of God:.
He endures always and is present everywhere, and by existing always and everywhere he constitutes duration and space. Since each and every particle of space is alwaysand each and every indivisible moment of duration is everywherecertainly the maker and lord of all things will not be never or nowhere … God is one and the same God always and everywhere. He is omnipresent not only virtually but also substantially ; for active power cannot subsist without substance.
For Newton, just as bodies are present in some spatial location, sir isaac newton essay, God, an infinite being, is present throughout all of space throughout all of time. There could not be a clearer expression of agreement with More in his debate sir isaac newton essay the Cartesians concerning the substantial presence of the divine within space, sir isaac newton essay.
Newton also took issue with Cartesian ideas about motion. This text influenced nearly every subsequent philosophical discussion of space and time for the next three centuries, so its contours are well known see DiSalle ch. This tension runs deep in the Cartesian system. He distinguishes between absolute and relative motion, true and apparent motion, and mathematical and common motion the same distinctions hold for time, space and place.
The former item in each of these three pairings is a concept that coheres with the laws of motion, sir isaac newton essay. That is, true motion should be understood as absolute motion. This means, in turn, that we must distinguish between the common idea of space, according to which space is conceived of as involving relations among various objects like the space of our airand the mathematical idea, one presumably obtained from geometrical reasoning, that space is independent of any objects or their relations.
