Locke: Philosophy of Science, Misc

The aim of this text is to investigate a little-known aspect of John Locke’s work: the relationship between philosophy and his medical practice. This theme is justified because his philosophical conception is widely known, but his studies in the field of medicine are practically ignored in Brazil. To accomplish this task, the article is divided into threeparts: in the first, we will address the debate on English medical practice in the seventeenth century; in the second, Locke’s penchant for medicine and, (...) finally, in the third, Locke’s medical practice. We hope that this text can contribute to the advancement of research on John Locke in Brazil,especially on his relationship with medicine. (shrink)

How does Locke contribute to the development of 18th-century projects for a science of the mind, even though he seems to reject or at least bracket off such an idea himself? Contrary to later understandings of empiricism, Locke goes out of his way to state that his project to investigate and articulate the ‘logic of ideas’ is not a scientific project: “I shall not at present meddle with the Physical consideration of the Mind” (Essay, I.i.2). Locke further specifies that this (...) means his analysis of mental processes will not engage with knowledge of the brain (e.g. in terms of corpuscles and animal spirits), even though he had been the student of Thomas Willis. Now, Kant seemed to make an elementary mistake, given such a clear statement on Locke’s part, when he claimed that Locke’s project was a “physiology of the understanding” (in the Preface to the A edition of the first Critique). One can ask of course what this physiology of the understanding was, and if it existed, in or out of the Lockean intellectual world (as I have sought to investigate in a 2016 paper). This leads me to inquire into the outcome of his empiricism for a scientific treatment of the mind, including in the sense of a ‘naturalization’ of the mind (with implications also for our understanding of empiricism: Anstey’s influential distinction between experimental and speculative philosophy does not seem useful here). Because if Kant made this charge, there were also many 18th-century thinkers who positively treated Locke as their great forerunner in psychology and related fields: Charles Bonnet and Joseph Priestley among them, just as some prominent physicians such as Cabanis claimed to be ‘finishing the job’ that Locke had started in, e.g. their materialist theories of the passions. What one might term ‘the Locke Problem’ here is: how can one reconcile empiricism and claims about cerebral processes, while seeking to remain a Lockean? Differently put, what is the process of naturalization, a naturalization of? (shrink)

It is often claimed that classification, on Locke’s view, proceeds by attending to similarities between things, and it is widely argued that nothing about the sensible similarities between things determines how we are to sort them, in which case sorting substances at the phenomenal level must be arbitrary. However, acquaintance with the “internal” or hidden qualities of substances might yet reveal objective boundaries. Citing what I refer to as the Watch passage in Locke’s Essay (henceforth Watches), many commentators claim that (...) classification at the microphysical level must also be arbitrary. They conclude that sorting is arbitrary at any level of description. I refer to this as the standard reading of Locke on classification. In this paper I argue that Locke does not claim that sorting is arbitrary, either at the phenomenal level, or at the microphysical level. First, Locke does not claim in Watches that sorting is arbitrary at the microphysical level. The existence or nonexistence of objective boundaries at the microphysical level is not Watches’ topic and the passage is in fact silent on that question. Here, the standard reading mistakes a claim about the nature of the task of locating “specific differences” for a claim about the nature of the task of classification. This diagnosis proves instructive, for I argue that a similar conflation underwrites the standard reading’s claim that sorting at the phenomenal level must be arbitrary. Far from arbitrarily choosing how to sort things in terms of their phenomenal similarities, Locke thought that the mind simply follows nature’s lead. This characterization of the mind’s activity, I go on to argue, accords well with Locke’s claim that species are the workmanship of the understanding. (shrink)

The overarching theme of Locke’s Image of the World, by Michael Jacovides, is that Locke’s belief in the best science of his day shapes his philosophy in important ways. Jacovides contends that “by understanding the scientific background to Locke’s thoughts, we can better understand his work” (1), including both his positions and his arguments for those positions. To a lesser extent, Jacovides’s book also treats Locke as a case study in thinking about how much scientific theory should influence philosophy. While (...) much of the science Locke relies on is incomplete or problematic, and so leads him into errors, Jacovides is sympathetic to Locke’s approach of using the best scientific theories to help develop and justify his philosophical positions. Throughout the book Jacovides shows how science – Locke’s study of medicine, and later Boyle’s corpuscularianism, and then later Newton’s physics – influence Locke’s thinking on a variety of topics. The result is an impressive account of the history of science at a critical point in its development through the lens of one of the great philosophers of that time. (shrink)

Many commentators have argued that Locke understood laws of nature as causally efficacious. On this view the laws are causally responsible for the production of natural phenomena. This paper argues that this interpretation faces serious difficulties. First, I argue that it will be very difficult to specify the ontological status of these laws. Proponents of the view suggest that these laws are divine volitions. But I argue that this will be difficult or impossible to square with Locke’s nominalism. Second, I (...) argue that it will be difficult to specify the manner in which these laws operate. The view runs the risk of collapsing into occasionalism and Locke has measured critiques of the occasionalist position. The only way to maintain that laws are causally efficacious divine volitions while avoiding occasionalism is to have God engage in what I call ‘brute fact-making’. But brute fact-making is difficult to square with Locke’s remarks on God’s action in the world and with his standards for explanation in natural philosophy. (shrink)

The introduction considers the state of scholarship on empiricism as a philosophical and historical category, particularly as it pertains to experimental philosophy. It concludes that empiricism properly understood is a rich category encompassing epistemic, semantic, methodological, experimental, and moral elements. Its richness makes it a suitable lens through which to account for actual historical complexity. The introduction relates the category to the work of Sir Isaac Newton, who influenced all of empiricism’s elements.

Locke is famous for defining madness as an intellectual disorder in the realm of ideas. Numerous commentators take this to be his main and only contribution to the history of psychiatry. However, a detailed exegetical review of all the relevant textual evidence suggests that this intellectualist interpretation of Locke’s account of madness is both misleading and incomplete. Affective states of various sorts play an important role in that account and are in fact primordial in the determination of human conduct generally. (...) Locke’s legacy in this domain must therefore be revised and the intellectualist bias that dominates discussions of his views must be redressed. (shrink)

The purpose of this paper is to elucidate two interesting parallels between views discussed in John Wilkins’ Of the Principles and Duties of Natural Religion and positions developed by John Locke in his Essay Concerning Human Understanding. The first parallel pertains to a faculty of inner sense. Both authors carve out a central role for this introspective perceptual modality. The second parallel pertains to volition and free will. Both authors employ an investigative methodology which privileges first-personal experiences of choosing and (...) willing. I also discuss the relationship between these two parallels and speculate about their significance. (shrink)

It is well-known that Isaac Newton’s conception of space and time as absolute -- “without reference to anything external” (Principia, 408) -- was anticipated, and probably influenced, by a number of figures among the earlier generation of seventeenth century natural philosophers, including Pierre Gassendi, Henry More, and Newton’s own teacher Isaac Barrow. The absolutism of Newton’s contemporary and friend, John Locke, has received much less attention, which is unfortunate for several reasons. First, Locke’s views of space and time undergo a (...) dramatic evolution that mirrors the overall absolutist trend of the era. Second, there are good reasons to suppose that Locke was influenced late in this evolution by Newton’s Principia, which he read and reviewed shortly after its 1687 publication. It is even possible that Locke read or knew of the earlier and unpublished, though now famous, Newtonian tract De Gravitatione. Third, despite the influence of Newton, Locke’s retains a skeptical attitude concerning our empirical knowledge of absolute space and time. He is especially cautious about absolute time, bucking a widespread tendency to treat time as strongly analogous to space. Their disagreement about the measure of absolute time, we will suggest, reflects a deeper disagreement in the philosophy of science. While Locke counts as scientific knowledge only ideas and demonstrations derivable from immediate experience, Newton endorses a more theory-driven brand of empiricism, which holds that our best explanations of the phenomena provide genuine knowledge that goes beyond what we can directly observe.

This paper examines the way in which Locke's deep and longstanding interest in the non-European world contributed to his views on species and their classification. The evidence for Locke's curiosity about the non-European world, especially his fascination with seventeenth-century travel literature, is presented and evaluated. I claim that this personal interest of Locke's almost certainly influenced the metaphysical and epistemological positions he develops in the Essay. I look to Locke's theory of species taxonomy for proof of this. I argue that (...) Locke uses evidence gathered from the non-European world to (1) show that in taxonomizing objects we rely on their sensible qualities rather than their real essences and to (2) undermine Scholastic Aristotelian views about a mind-independent species/genera structure to the world.

The paper examines the copious correspondence between the English philosopher John Locke and the French intellectual Nicolas Toinard ; Locke made the acquaintance of Toinard in Paris in 1677 or early in 1678, and the latter remained his lifelong friend and most assiduous correspondent. An Orléanais and a devout Catholic, Toinard combined an intense interest in the Scriptures with an enthusiasm for experimental science and inventions of every kind; he introduced Locke to all the French official institutions and to a (...) number of private laboratories. Toinard’s principal work, Evangeliorum Harmonia Graeco-Latina, was greatly appreciated by Locke for its new method. The paper attempts to explore the bulk of this correspondence in detail, giving an account of the wide range of topics dealt with in the two hundred letters; it is divided into four paragraphs referring, respectively, to the years 1678-1679, 1679-1681, 1681-1686, 1686-1704. The perspective is diachronic; on some occasions, the focus is on a particular topic which is the object of prolonged discussion between the two correspondents. In the conclusion, attention is drawn to the relevance of this correspondence in the context of the 17th century and of Locke’s philosophical thought. (shrink)

In this groundbreaking book, Steven Forde argues that John Locke's devotion to modern science deeply shaped his moral and political philosophy. Beginning with an account of the classical approach to natural and moral philosophy, and of the medieval scholasticism that took these forward into early modernity, Forde explores why the modern scientific project of Francis Bacon, Pierre Gassendi, Robert Boyle and others required the rejection of the classical approach. Locke fully subscribed to this rejection, and took it upon himself to (...) provide a foundation for a compatible morality and politics. Forde shows that Locke's theory of moral 'mixed modes' owes much to Pufendorf, and is tailored to accommodate science. The theory requires a divine legislator, which in turn makes natural law the foundation of morality, rather than individual natural right. Forde shows the ways that Locke's approach modified his individualism, and colored his philosophy of property, politics and education. (shrink)

Serious philosophical reflection on the nature of experiment began in earnest in the seventeenth century. This paper expounds the most influential philosophy of experiment in seventeenth-century England, the Bacon-Boyle-Hooke view of experiment. It is argued that this can only be understood in the context of the new experimental philosophy practised according to the Baconian theory of natural history. The distinctive typology of experiments of this view is discussed, as well as its account of the relation between experiment and theory. This (...) leads into an assessment of other recent discussions of early modern experiment, namely, those of David Gooding, Thomas Kuhn, J.E. Tiles and Peter Dear. (shrink)

This is a review of Peter Anstey's John Locke and Natural Philosophy.

Peter Anstey presents a thorough and innovative study of John Locke's views on the method and content of natural philosophy. Focusing on Locke's Essay concerning Human Understanding, but also drawing extensively from his other writings and manuscript remains, Anstey argues that Locke was an advocate of the Experimental Philosophy: the new approach to natural philosophy championed by Robert Boyle and the early Royal Society who were opposed to speculative philosophy. On the question of method, Anstey shows how Locke's pessimism about (...) the prospects for a demonstrative science of nature led him, in the Essay, to promote Francis Bacon's method of natural history, and to downplay the value of hypotheses and analogical reasoning in science. But, according to Anstey, Locke never abandoned the ideal of a demonstrative natural philosophy, for he believed that if we could discover the primary qualities of the tiny corpuscles that constitute material bodies, we could then establish a kind of corpuscular metric that would allow us a genuine science of nature. It was only after the publication of the Essay, however, that Locke came to realize that Newton's Principia provided a model for the role of demonstrative reasoning in science based on principles established upon observation, and this led him to make significant revisions to his views in the 1690s. On the content of Locke's natural philosophy, it is argued that even though Locke adhered to the Experimental Philosophy, he was not averse to speculation about the corpuscular nature of matter. Anstey takes us into new terrain and new interpretations of Locke's thought in his explorations of his mercurialist transmutational chymistry, his theory of generation by seminal principles, and his conventionalism about species.

This is the introduction to a collection of essays on 'embodied empiricism' in early modern philosophy and the life sciences - papers on Harvey, Glisson, Locke, Hume, Bonnet, Lamarck, on anatomy and physiology, on medicine and natural history, etc.

This volume focuses on the development of empiricism as an interest in the body - as both the object of research and the subject of experience.

The Flow of Influence: From Newton to Locke - and Back- In this essay, the affinity between Locke’s empiricism and Newton’s natural philosophy is scrutinized. Parallels are distinguished from influences. I argue, pace G.A.J. Rogers, that Newton’s doctrine of absolute space and time influenced Locke’s Essay concerning Human Understanding from the second edition onwards. I also show that Newton used Lockean terminology in his criticism of Cartesianism. It is further argued that Locke’s endorsement of corpuscularianism is merely methodological, i.e. he (...) accepts it as a scientifically useful and psychologically intelligible paradigm, but not as a realist explanation of rerum natura. Like Newton, Locke was reluctant to accept the corpuscular theory of light. However, his reasons for doing so were different from those of Newton. This essay is divided into three parts: in the first, the stage is set by looking at the fundamentals of Locke’s epistemology; in the second, several correspondences between Locke’s and Newton’s thought are explored and two cases of influence are argued for; and in the third, several arguments are provided for interpreting Locke’s corpuscularianism as methodological.

This paper gives a detailed analysis of four seed lists in the journals of John Locke. These lists provide a window into a fascinating open network of botanical exchange in the early 1680s which included two of the leading botanists of the day. Pierre Magnol of Montpellier and Jacob Bobart the Younger of Oxford. The provenance and significance of the lists are assessed in relation to the relevant extant herbaria and plant catalogues from the period. The lists and associated correspondence (...) provide the main evidence for Locke's own important, through modest contribution to early modern botany, a contribution which he would have regarded as a small part of the broader project of constructing a natural history of plants. They also provide a detailed case study of the sort of open and informal network of knowledge exchange in the early modern period that is widely recognised by historians of science, but all too rarely illustrated.

This article examines questions connected with the two features of Locke's intellectual landscape that are most salient for understanding his philosophy of science: (1) the profound shift underway in disciplinary boundaries, in methodological approaches to understanding the natural world, and in conceptions of induction and scientific knowledge; and (2) the dominant scientific theory of his day, the corpuscular hypothesis. Following the introduction, section 2 addresses questions connected to changing conceptions of scientific knowledge. What does Locke take science (scientia) and scientific (...) knowledge to be generally, why does he think that scientia in natural philosophy is beyond the reach of human beings, and what characterizes the conception of human knowledge in natural philosophy that he develops? Section 3 addresses the question provoked by Locke's apparently conflicting treatments of the corpuscular hypothesis. Does he accept or defend the corpuscular hypothesis? If not, what is its role in his thought, and what explains its close connection to key theses of the Essay? Since a scholarly debate has arisen about the status of the corpuscular hypothesis for Locke, Section 3 reviews some main positions in that debate. Section 4 considers the relationship between Locke's thought and that of a figure instrumental to the changing conceptions of scientific knowledge, Isaac Newton. (shrink)

In this paper we suggest a revisionist perspective on two significant figures in early modern life science and philosophy: William Harvey and John Locke. Harvey, the discoverer of the circulation of the blood, is often named as one of the rare representatives of the ‘life sciences’ who was a major figure in the Scientific Revolution. While this status itself is problematic, we would like to call attention to a different kind of problem: Harvey dislikes abstraction and controlled experiments (aside from (...) the ligature experiment in De Motu Cordis), tends to dismiss the value of instruments such as the microscope, and emphasizes instead the privileged status of ‘observed experience’. To use a contemporary term, Harvey appears to rely on, and chiefly value, ‘tacit knowledge’. Secondly, Locke’s project is often explained with reference to the image he uses in the Epistle to the Reader of his Essay, that he was an “underlabourer” of the sciences. In fact, despite the significant medical phase of his career, Locke’s ‘empiricism’ turns out to be above all a practical (i.e. ‘moral’) project, which focuses on the delimitation of our powers in order to achieve happiness, and rejects the possibility of naturalizing knowledge. When combined, these two cases suggest a different view of some canonical moments in early modern natural philosophy. (shrink)

This landmark study examines the role played by the rediscovery of the writings of the ancient atomists, Epicurus and Lucretius, in the articulation of the major philosophical systems of the seventeenth century, and, more broadly, their influence on the evolution of natural science and moral and political philosophy. The target of sustained and trenchant philosophical criticism by Cicero, and of opprobrium by the Christian Fathers of the early Church, for its unflinching commitment to the absence of divine supervision and the (...) finitude of life, the Epicurean philosophy surfaced again in the period of the Scientific Revolution, when it displaced scholastic Aristotelianism. Both modern social contract theory and utilitarianism in ethics were grounded in its tenets. Catherine Wilson shows how the distinctive Epicurean image of the natural and social worlds took hold in philosophy, and how it is an acknowledged, and often unacknowledged presence in the writings of Descartes, Gassendi, Hobbes, Boyle, Locke, Leibniz, Berkeley. With chapters devoted to Epicurean physics and cosmology, the corpuscularian or "mechanical" philosophy, the question of the mortality of the soul, the grounds of political authority, the contested nature of the experimental philosophy, sensuality, curiosity, and the role of pleasure and utility in ethics, the author makes a persuasive case for the significance of materialism in seventeenth-century philosophy without underestimating the depth and significance of the opposition to it, and for its continued importance in the contemporary world. Lucretius's great poem, On the Nature of Things, supplies the frame of reference for this deeply-researched inquiry into the origins of modern philosophy. (shrink)

This paper argues that the English philosopher John Locke, who has normally been thought to have had only an amateurish interest in botany, was far more involved in the botanical science of his day than has previously been known. Through the presentation of new evidence deriving from Locke’s own herbarium, his manuscript notes, journal and correspondence, it is established that Locke made a modest contribution to early modern botany. It is shown that Locke had close and ongoing relations with the (...) Bobarts, keepers of the Oxford Botanic Garden, and that Locke distributed seeds and plant parts to other botanists, seeds of which the progeny almost certainly ended up in the most important herbaria of the period. Furthermore, it is claimed that the depth of Locke’s interest in and practice of botany has a direct bearing on our understanding of his views on the correct method of natural philosophy and on the interpretation of his well known discussion of the nature of species in Book III of his Essay concerning human understanding.

Hume follows Newton in replacing the mechanical philosophy’s demonstrative ideal of science by the Principia’s ideal of inductive proof ; in this respect, Hume differs sharply from Locke. Hume is also guided by Newton’s own criticisms of the mechanical philosophers’ hypotheses. The first stage of Hume’s skeptical argument concerning causation targets central tenets of the mechanical philosophers’ conception of causation, all of which rely on the a priori postulation of a hidden configuration of primary qualities. The skeptical argument concerning the (...) causal inductive inference then raises doubts about what Hume himself regards as our very best inductive method. Hume’s own “Rules” further substantiate his reliance on Newton. Finally, Locke’s distinction between “Knowledge” and “Probability” does not leave room for Hume’s Newtonian notion of inductive proof.

This paper aims at showing that F. Bacon and R. Boyle's English experimental philosophy, particulatly the corpuscular philosophy of the latter, was essential to the construction of J. Locke's experimental philosophy. It will be shown that according to author of the Essay on Human Understanding we can only reach the knowledge of some of the propertirs of the bodies through the effects they have on us, without us ever being able to know the ultimate substance they are made of. These (...) issues may help us explain the meanining of the notion of matter for 17th English philosophy, with its importat distinction between primary and secondary qualities and, moreover, the proposal to constitute an experimental science in Boyle and Lockes's philosophies.
