Notes on Contributors

Peter R. Anstey is an ARC Future Fellow and Professor of Philosophy in the School of Philosophical and Historical Inquiry at the University of Sydney. He specializes in early-modern philosophy with a special focus on the philosophy of leading English philosophers including John Locke, Robert Boyle, and Francis Bacon. He is the author of John Locke and Natural Philosophy (Oxford University Press, 2011) and editor (with Lawrence M. Principe) of the Clarendon edition of John Locke: Writings on Natural Philosophy and Medicine, forthcoming.

Richard J. Arneson is Professor of Philosophy, and occupies the Valtz Family Chair in Philosophy, at the University of California, San Diego. He also codirects the Institute for Law and Philosophy at UCSD's School of Law. He is the author of more than 100 articles on a wide range of topics in political philosophy. His recent current research is on distributive justice. Some of this work explores how one might best incorporate a reasonable account of personal responsibility into a broadly egalitarian theory of justice. He also considers how consequentialist morality might be developed in a version that is appealing and appropriately responsive to its critics. This latter project involves exploring the structure of moderate deontology to identify the best rival of consequentialism.

Introduction

MATTHEW STUART

The influence of John Locke's career as a writer is so great that one can forget what a rich and varied life he led. His contributions to political theory and to epistemology have had such an impact that one can overlook what a remarkable polymath he was. He began his career as an academic, but spent much of it in the service of Anthony Ashley Cooper, who was Chancellor of the Exchequer when they met, and later Lord Chancellor. This association brought Locke close to the upper echelons of political power, and involved him in economic and New World policy making. In the aftermath of the Rye House plot against Charles II and his brother James, it also placed Locke in real danger, prompting him to flee the country and to spend five and a half years in exile, sometimes under an assumed name. Locke was a physician, a serious student of chemistry, and a collector of botanical specimens. He was a metaphysician, a theologian, a civil servant, and an economic theorist. He was the friend of Boyle and Newton, a Fellow of the Royal Society, a keeper of extensive meteorological records. He theorized about the best means of educating children, wrote a lengthy exegesis of the Epistles of St Paul, and devised a method for indexing commonplace books that was widely adopted for 100 years.

The present volume focuses primarily on Locke's contributions to philosophy, but philosophy broadly construed. The plan of the book is designed to achieve breadth as well as depth. There is thorough coverage of most of the topics in Locke's philosophy that receive much attention from scholars. These include, among others, his empiricist theory of ideas, his distinction between primary and secondary qualities, and his account of personal identity. They include his theory of natural rights, his understanding of the social contract, his arguments on religious toleration. Yet this book also contains chapters on relatively neglected sectors of Locke's oeuvre, such as the drafts of the Essay concerning Human Understanding, the correspondence with Stillingfleet, and the Reasonableness of Christianity. In addition, it pays considerable attention to the context in which Locke developed his philosophical theories, and to their influence going forward. Thus there are chapters on his relations to the scholastics and Descartes, and chapters that trace his influence on British empiricism, the liberal tradition, and the New World.

All of the chapters that follow have been commissioned specifically for this volume. The authors include many of the best known, and most highly regarded, scholars who have worked on Locke over the last few decades. They also include a few of the most talented members of a promising new generation of Locke scholars. It is safe to say that Locke scholarship is flourishing now in a way that it was not 50 years ago. Each of the chapters in this volume makes some attempt to acquaint the reader with the current state of this scholarship within a specific domain. Many of them also aspire to push that scholarship forward a significant step or two. The result is a collection that should be of real use to general readers and professional philosophers alike. Let us survey the ground to be covered.

Life and Background

Locke lived in dramatic times. He grew to manhood during the English Civil War, saw the restoration of the Stuart monarchy while a student at Christ Church, and celebrated the Dutch invasion of England in 1688 that made possible his return from exile. The remarkable changes he lived through were not just political. There was, for example, the Great Plague of London in 1665, and the Great Fire that destroyed much of that city the following year – though Locke learned of both of these momentous events from a safe distance, at Oxford. There was also the remarkable expansion of scientific knowledge in England in the second half of the seventeenth century: the invention of calculus, the development of air pumps and microscopes as serious tools for scientific investigation, the publication of Newton's Principia. These events shaped the intellectual world that Locke inhabited, and to which he contributed so much.

In Chapter 1, Mark Goldie charts the course of Locke's progress through these times. He tells us of Locke's relatively humble beginnings, his education at Westminster School and Oxford. He tells us of Locke's reluctance to take the holy orders that his Christ Church studentship required, and of his success in obtaining a dispensation to avoid doing so. Locke's service in Shaftesbury's household began in 1667, and he soon became involved in many of his employer's projects. He also initiated some of his own, drafting a work that he would later expand into the Essay concerning Human Understanding, and writing the Two Treatises of Government. Shaftesbury died in 1683, the year Locke's peripatetic exile in Holland began. The Essay and the Two Treatises were not published until his return to England in 1689. More publications soon followed, and Goldie helps us to understand both the praise and criticism they earned Locke. He also describes how, during the philosopher's final years, he was protected from the pressures of both fame and notoriety by his quiet retirement at Oates, the family home of his friend Damaris Cudworth Masham.

In sketching the major events of Locke's life, Goldie does not neglect the political context that informed his theorizing about the nature and extent of political authority. Nor does he fail to touch on Locke's involvement with natural science, his antagonism to scholasticism, his acknowledged debt to Descartes. Yet each of these topics is worthy of fuller exploration, and that is what we get in the next four chapters.

In Chapter 2, Jacqueline Rose describes several contexts that figure in Locke's evolution as a political theorist. Perhaps the most obvious is the autocratic nature of Charles II's rule, though Rose is keen to draw our attention to a variety of other factors as well. There is the tension caused by religious divides: unease fueled by fears of sectarian instability on the one side, and of popery on the other. It was the crisis of 1679 to 1681/1682 – in which Charles II blocked Shaftesbury and his supporters' attempts to exclude the Catholic Duke of York from succession to the throne, and punished their actions – that immediately prompted Locke to write the Two Treatises, a work directed against the actions of a presently existing “popish” and “arbitrary” government, as well as any that might exist in the future. Yet Rose suggests that this work is also haunted by memories of the upheavals caused by the earlier Civil War. Locke's main targets are the errors of a tyrannical monarch, but she says that he is also mindful of Parliamentarian excesses during the Civil War, and alive to the possibility that a parliament too can be tyrannical. Other factors that Rose examines include the increase in political partisanship (if not the emergence of actual political parties), and the growth of a public sphere dominated by the printed word. Thinking particularly of Locke's writings on toleration, she points to the importance of his experience of peaceful religious coexistence in the Dutch republic, and to what he must have known about the influx of Protestant refugees from France after Louis XIV revoked the Edict of Nantes, which had protected that religious minority.

Just as we must look to social and political developments in England to understand the impetus for much of Locke's political theorizing, so we must appreciate his engagement with natural science – what was then called “natural philosophy” – if we are to adequately frame the central concerns of his Essay concerning Human Understanding. We are informed by his friend James Tyrrell that it was discussions about the foundations of morality and religion that first prompted Locke to write an essay on epistemology (Woolhouse 2007, 98). Nevertheless, he makes it clear from the outset of the published work that his project has important connections to the larger enterprise of expanding our knowledge of the natural world. In his “Epistle to the Reader,” Locke famously describes his role as that of “an Under-Labourer” who clears the ground a little so that the work of such “Master-Builders” as Boyle and Newton is not impeded by the confusions attendant upon the misuse of language. He is alluding to his discussion in Book III about various abuses of language and how to avoid them. Yet it is not only in Book III that Locke's engagement with natural philosophy is in evidence. Many of the central questions of the Essay – about how knowledge is grounded in experience, and how things are ranked into kinds, about which features of bodies are more basic, and what are the prospects for a demonstrative science of bodies – are questions raised by his reflection on, and participation in, research in physics, chemistry, botany, and medicine.

If Locke was less than a full-fledged natural philosopher, he was more than a dilettante. He had a serious interest in medicine and chemistry dating as far back as the 1650s, and by the end of that decade he was doing an enormous amount of reading and note taking on these subjects (Woolhouse 2007, 461). Early in the next decade he became friends with Boyle, attended lecture courses on medicine and chemistry, and broadened his reading in natural philosophy to include, among other things, Descartes' writings on physics, optics, and meteorology (Milton 2001). In the middle of the 1660s, Locke set up a chemical laboratory with his friend David Thomas, and also became the associate of an important London physician, Thomas Sydenham, who did much to introduce him to medical practice and also to shape his views about medical theory (Milton 2001). In 1675 Locke was awarded the degree of Bachelor of Medicine (Woolhouse 2007, 116). Though travel and the association with Shaftesbury eventually placed many other demands on his attention, his interest in medicine and natural philosophy continued for the rest of his life. Thus, during his exile in Holland we find him discussing colic with Dutch medical men (Woolhouse 2007, 203), and writing reviews of works by Boyle and Newton for the Bibliothèque universelle (Anstey 2011, 2–3). As late as the 1690s, when he had become Boyle's literary executor, he had his manservant copy hundreds of pages of chemical notes from Boyle's papers (Anstey 2011, 176).

In Chapter 3, Peter Anstey describes Locke's engagement with natural philosophy, while also exploring several tensions in his philosophy of science. The first tension involves competing views about scientific method: one that permits speculative hypotheses about unobservable causal mechanisms, and the other a neo-Baconian approach that discourages such hypotheses and recommends instead the collection of “natural histories.” Anstey says that Locke is committed to the method of natural history, but that this commitment sits uneasily with his allegiance to corpuscularianism. Another tension that Anstey locates is that between Locke's view that natural philosophy should be grounded in observation and his allegiance to something like the Aristotelian ideal of scientific knowledge as demonstrative knowledge. By Locke's own lights, a demonstrative science of bodies is probably unachievable, though Anstey suggests that he allows that we might make progress in that direction if we could make exact measurements of corpuscular structures. Finally, Anstey sees some tension between Locke's earlier methodological pronouncements and his growing appreciation – in the 1690s – of Newton's achievement in the Principia. In the Essay and elsewhere, Locke says disparaging things about the idea of founding a system of knowledge on principles or maxims, and yet one could say that Newton managed to do just that. Anstey concludes that Locke's views about scientific method were still evolving late in his life.

Locke's Essay is an ambitious, wide-ranging philosophical book, not a narrow treatise on the philosophy of science. It is a work influenced by, and written in reaction to, not just the science of its day, but also the philosophical writings of its author's contemporaries and near-contemporaries. The philosophies that loom largest in the background of Locke's own are those of the scholastics and Descartes. His relation to scholasticism is the subject of an essay by E.J. Ashworth (Chapter 4), and Lisa Downing (Chapter 5) explores his response to Descartes.

The most casual reader of the Essay will see that Locke's relations to both the scholastics and Descartes are largely antagonistic. His references to them are almost always critical, and he is sometimes dismissive or even derisive. What Ashworth and Downing offer us is a more nuanced picture of just how well or poorly he understands some of his predecessors' views, and how thoroughly or incompletely he rejects them. The results are something of a mixed bag, though it is fair to say that his engagement with Descartes' philosophy is more serious than is his engagement with the scholastics'. Ashworth suggests that this is partly because much of his exposure to scholasticism came not from the study of great works by Aquinas, Scotus, and Ockham, but from acquaintance with textbooks written by competent but second-rate authors. On one subject – the nature of substance – Locke actually claimed to agree with the scholastics, but Ashworth shows that the similarity between their accounts is only superficial. Where she does find some evidence of scholastic influence is not in Locke's metaphysics, but in his logic and philosophy of language.

Though one can see a Cartesian influence in Locke's conception of ideas, and in his characterization of intuitive and demonstrative knowledge, he rejects the basic tenets of Descartes' philosophy. Whereas Descartes claims to know that the whole essence of body is extension, and the world a plenum, Locke argues against the identification of body and extension, and for the possibility of a vacuum. While Descartes claims that thinking is the essence of mind, Locke challenges the Cartesian result that we are always thinking. Descartes is also a target of Locke's critique of innatism, and his remarks about skepticism.

Locke finds little enough to praise in Descartes' philosophy but if Downing is right, he respects the French philosopher enough to read him very carefully. She sees Locke as responding not only to positions that Descartes takes in well-known passages in the Meditations and the Principles of Philosophy, but also to Descartes' subtle defenses of these in the Reply to Gassendi, and in his correspondence. What this suggests is that although Locke may regard scholasticism as an already moribund tradition – and so not worth the trouble of a careful refutation – he views Descartes' philosophy as a force to be reckoned with. And reckon he does. When he began writing the earliest version of the Essay concerning Human Understanding, it was not with the goal of offering the world an antidote to Cartesian epistemology and metaphysics. Yet it was not long before that ambition grew within him.

Metaphysics and Epistemology

We are most fortunate that portions of several early drafts of the Essay survive, affording us a fascinating look at Locke's growing ambitions over the long period of its composition. Two of these early drafts – now referred to as Draft A and Draft B – bear the date 1671 but as J. R. Milton explains in Chapter 6, at least some portions of the second draft might have been composed in 1672. A third manuscript, now called Draft C, is dated 1685. (It is clear that many other manuscripts once existed that have since been lost.) Locke's commitment to empiricism is there from the first line of Draft A, though a sustained volley against innatism does not make its appearance until Draft B. Draft A also contains a discussion of Descartes' account of body, and an explicit rejection of the Cartesian view that sensory beliefs stand in need of some kind of justification. Locke's antagonism to Descartes' system thus makes its appearance early on. Curiously, some of the important elements of his own system do not make theirs until later. For example, Drafts A and B make reference neither to the distinction between primary and secondary qualities, nor to that between real and nominal essences.

It is in Draft B that Locke first tells us that his purpose is to “enquire into the Originall, Certainty & Extent of humane knowledge. togeather with the ground<s> & degrees of Opinion Belief Perswasion or Assent” (B, 2). That declaration reappears, with minor cosmetic changes, in the Introduction to the Essay
