I must begin by confessing that I owe to the deficiencies of voice-mail a valuable occasion to re-think the purpose of this lecture. For I left on the voice-mail of Professor Martin the title of the lecture: “Augustine and a Crisis of Wealth in Late Antiquity.” I received—again by voice-mail—a delighted reply. He fully approved of my title: “Augustine and a Crisis of Wills in Late Antiquity.” I realized, to my shame, that I had awoken false expectations in the heart (...) of a great Augustinian scholar. Of course, “Wills” is what a St Augustine Lecture should be about. It was on the Will that Augustine wrote with greatest passion and tenacity, and with the gravest long-term consequences. And I had offered, for the occasion of a St. Augustine Lecture, not “Will” but merely “Wealth.”. (shrink)

We used a participatory approach and a rural livelihoods framework to explore the knowledge and capacity of southeast Queensland graziers to adapt to climate change. After being presented with information on climate change projections, participants identified biophysical and socio-economic opportunities and challenges to adaptation. Graziers identified key opportunities as components of resilience, and in many cases were options that they had some knowledge of either from their own region or elsewhere in the grazing industry. The major constraint to adaptation was (...) the lack of financial capital: with low profitability of the industry and high land costs restricting their capacity to diversify and exploit economies of scale. These constraints were exacerbated by the pressure many graziers experienced from the demand for land as a result of urban expansion. While the focus of the workshop was on the impact of climate change and capacity to adapt, many of the issues raised by graziers were pressures not solely related to climate change. Adaptation needs to be considered in light of the appropriate level and spatial scale required to tackle the issues identified. Policy needs to support good natural resource management, rural amenity, and food and fibre production close to urban population and markets in the face of urban encroachment. (shrink)

It is argued that awareness of the distinction between dynamical and variational symmetries is crucial to understanding the significance of Noether's 1918 work. Specific attention is paid, by way of a number of striking examples, to Noether's first theorem, which establishes a correlation between dynamical symmetries and conservation principles.

The aim of this paper is to illustrate four properties of the non-relativistic limits of relativistic theories: that a massless relativistic field may have a meaningful non-relativistic limt, that a relativistic field may have more than one non-relativistic limit, that coupled relativistic systems may be "more relativistic" than their uncoupled counterparts, and that the properties of the non-relativistic limit of a dynamical equation may differ from those obtained when the limiting equation is based directly on exact Galilean kinematics. These properties (...) are demonstrated through an examination of the non-relativistic limit of the familiar equations of first-quantized QED, i.e., the Dirac and Maxwell equations. The conditions under which each set of equations admits non-relativistic limits are given, particular attention being given to a gauge-invariant formulation of the limiting process especially as it applied to the electromagnetic potentials. The difference between the properties of a limiting theory and an exactly Galilean covariant theory based on the same dynamical equation is demonstrated by examination of the Pauli equation.

Barley aleurone cells have long served as a model system for studying the regulation of gene expression in plants. In this review we survey what is known about hormone‐regulated gene expression in aleurone cells. We also describe the effects of heat stress on gene expression in this system, and speculate how the aleurone cell prioritizes its response between hormone‐induced and environment‐induced programs of gene expression.

Internal global symmetries exist for the free non-relativistic Schrodinger particle, whose associated Noether charges---the space integrals of the wavefunction and the wavefunction multiplied by the spatial coordinate---are exhibited. Analogous symmetries in classical electromagnetism are also demonstrated.

John Stuart Mill's Utilitarianism continues to serve as a rich source of moral and theoretical insight. This collection of articles by top scholars offers fresh interpretations of Mill's ideas about happiness, moral obligation, justice, and rights. Applying contemporary philosophical insights, the articles challenge the conventional readings of Mill, and, in the process, contribute to a deeper understanding of utilitarian theory as well as the complexity of moral life.

This introduction to the Common Knowledge symposium titled “Comparative Relativism” outlines a variety of intellectual contexts where placing the unlikely companion terms comparison and relativism in conjunction offers analytical purchase. If comparison, in the most general sense, involves the investigation of discrete contexts in order to elucidate their similarities and differences, then relativism, as a tendency, stance, or working method, usually involves the assumption that contexts exhibit, or may exhibit, radically different, incomparable, or incommensurable traits. Comparative studies are required to (...) treat their objects as alike, at least in some crucial respects; relativism indicates the limits of this practice. Jensen argues that this seeming paradox is productive, as he moves across contexts, from Lévi-Strauss's analysis of comparison as an anthropological method to Peter Galison's history of physics, and on to the anthropological, philosophical, and historical examples offered in symposium contributions by Barbara Herrnstein Smith, Eduardo Viveiros de Castro, Marilyn Strathern, and Isabelle Stengers. Comparative relativism is understood by some to imply that relativism comes in various kinds and that these have multiple uses, functions, and effects, varying widely in different personal, historical, and institutional contexts that can be compared and contrasted. Comparative relativism is taken by others to encourage a “comparison of comparisons,” in order to relativize what different peoples—say, Western academics and Amerindian shamans—compare things “for.” Jensen concludes that what is compared and relativized in this symposium are the methods of comparison and relativization themselves. He ventures that the contributors all hope that treating these terms in juxtaposition may allow for new configurations of inquiry. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:242 HISTORY OF PHILOSOPHY his political and religious predispositions prodded him to demonstrate that the roots of modern science were in the Christian Middle Ages. Sarton's particular foibles are best understood by referring them to his pacifist commitments and the moralistic assumption that the values of science are transferable to other human endeavors. Categories such as inductivism, conventionalism and Popperianism are of little help in gaining historical understanding. For (...) this, they are in fact Platonic ideals which have little heuristic value. I would venture that a truly historical historiography of science would aid us in spotting errors in the past and help us in the future. My guess is that a good analysis would reveal a major source of trouble to have stemmed from preconceived notions which the history of science was meant to illustrate. Surely some of them have been philosophical in character, and even Baconian or conventionalist. But until recent times, most of these preconceptions have stemmed from religious, nationalistic, or personal motivations, or from scientists who wanted support for a particular concept. I agree with Agassi only in the suggestion that a parti pris was at the root of our troubles. Why, then, substitute a Popperian preconception for a conventionalist one? Why not, on the contrary, combat their distorting influence and reduce their impact? This is in fact what has happened in recent times. As the history of science has fallen into the hands of a gradually organized profession, the blatant motivations --of any type--which colored past historical writings have slowly receded. By a constant and critical confrontation of opposing views among specialists, the purpose for examining the history of science has slowly been transformed. The older external motivations have given way to an interest in the subject for its own sake and a gradual transformation has been in the making for the last few decades. As happens in other human endeavors, professionalization has already raised the standards in the discipline and there is every reason to think it will continue to do so in the future. We need not really be as pessimistic as Agassi, nor embrace his particular salvation. ROGEa HAm~ University o] Cali]ornia, Berkeley A MEDIEVAL ANALYSIS OF INFINITY IN THE COURSEof arguing that time must have had a beginning, St. Bonaventure (1221-74) put forward a demonstration which in some ways seems to anticipate Cantor's definition of infinity.1 Bonaventure pointed out that, if the world were infinitely old, then there would have been an infinite number of annual revolutions of the sun around the ecliptic. But during each such period there occur (roughly) twelve revolutions of the moon, i.e. lunar months or lunations. Thus there would be one infinity which was twelve times another--which, says Bonaventure, is impossible. This attempted proof might be formulated as the following For other adumbrationsof this definition,see I. Thomas,"A TwelfthCentury Paradoxof the Infinite,"Journal o] Symbolic Logic, XXIII (1958), 133-134, and W. & M. Kneale, The Development of Logic (Oxford,1962),p. 440. NOTES AND DISCUSSIONS 243 reductio ad absurdum, in which a revolution of the sun is specified as the period between successive vernal equinoxes. If there could be an infinite set of past lunations, then clearly it could be put in a one-to-one correspondence with a proper sub-set of itself--viz., with the set of past lunar months during which vernal equinoxes occurred. But this consequence is preposterous; no set could be so correlated with its own sub-set. Therefore the set of past lunar months cannot be infinite, and the world must have had a beginning. The passage, which is found in Bonaventure's commentary on the Sentences of Peter Lombard, reads as follows :2 Si mundus est aeternus, revolutiones solis in orbe suo sunt infmitae ; rursus, pro una revolutions solis necesse est fuisse duodecim ipsius lunae: ergo plus revoluta est luna quam sol; et sol infinities: ergo infinitorum ex ea parle, qua infinita sunt, est reperire excessum.

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 article examines the views of René Descartes, Robert Boyle, and John Locke on essence and kinds and outlines the polemical stances that motivate and direct each of their views. It describes the ontological categories to which they subscribed and their own speculative theories about the actual kinds in the world. It categories to which they subscribed and their own speculative theories about the actual kinds in the world and discusses the late-Aristotelian theory of substantial forms.

Physical Relativity explores the nature of the distinction at the heart of Einstein's 1905 formulation of his special theory of relativity: that between kinematics and dynamics. Einstein himself became increasingly uncomfortable with this distinction, and with the limitations of what he called the 'principle theory' approach inspired by the logic of thermodynamics. A handful of physicists and philosophers have over the last century likewise expressed doubts about Einstein's treatment of the relativistic behaviour of rigid bodies and clocks in motion in (...) the kinematical part of his great paper, and suggested that the dynamical understanding of length contraction and time dilation intimated by the immediate precursors of Einstein is more fundamental. Harvey Brown both examines and extends these arguments, after giving a careful analysis of key features of the pre-history of relativity theory. He argues furthermore that the geometrization of the theory by Minkowski in 1908 brought illumination, but not a causal explanation of relativistic effects. Finally, Brown tries to show that the dynamical interpretation of special relativity defended in the book is consistent with the role this theory must play as a limiting case of Einstein's 1915 theory of gravity: the general theory of relativity.Appearing in the centennial year of Einstein's celebrated paper on special relativity, Physical Relativity is an unusual, critical examination of the way Einstein formulated his theory. It also examines in detail certain specific historical and conceptual issues that have long given rise to debate in both special and general relativity theory, such as the conventionality of simultaneity, the principle of general covariance, and the consistency or otherwise of the special theory with quantum mechanics. Harvey Brown' s new interpretation of relativity theory will interest anyone working on these central topics in modern physics. (shrink)

The emergence of experimental philosophy was one of the most significant developments in the early modern period. However, it is often overlooked in modern scholarship, despite being associated with leading figures such as Francis Bacon, Robert Boyle, Isaac Newton, Jean Le Rond d'Alembert, David Hume and Christian Wolff. Ranging from the early Royal Society of London in the seventeenth century to the uptake of experimental philosophy in Paris and Berlin in the eighteenth, this book provides new terms of reference for (...) understanding early modern philosophy and science, and its eventual eclipse in the shadow of post-Kantian notions of empiricism and rationalism. Experimental Philosophy and the Origins of Empiricism is an integrated history of early modern experimental philosophy which challenges the rationalism and empiricism historiography that has dominated Anglophone history of philosophy for more than a century.

This book presents the first integrated treatment of the philosophy of Robert Boyle, one of the leading English natural philosophers of the Scientific Revolution.

In the mid-seventeenth century a movement of self-styled experimental philosophers emerged in Britain. Originating in the discipline of natural philosophy amongst Fellows of the fledgling Royal Society of London, it soon spread to medicine and by the eighteenth century had impacted moral and political philosophy and even aesthetics. Early modern experimental philosophers gave epistemic priority to observation and experiment over theorising and speculation. They decried the use of hypotheses and system-building without recourse to experiment and, in some quarters, developed a (...) philosophy of experiment. The movement spread to the Netherlands and France in the early eighteenth century and later impacted Germany. Its important role in early modern philosophy was subsequently eclipsed by the widespread adoption of the Kantian historiography of modern philosophy, which emphasised the distinction between rationalism and empiricism and had no place for the historical phenomenon of early modern experimental philosophy. The re-emergence of interest in early modern experimental philosophy roughly coincided with the development of contemporary x-phi and there are some important similarities between the two. (shrink)

Armstrong's Materialist Theory of Mind is one of a handful of texts that began the physicalist revolution in the philosophy of mind. In this collection, distinguished philosophers examine what we still owe to it, how to expand it, as well as looking back on how it came about.

This paper argues that, contrary to the claims of Alan Chalmers, Boyle understood his experimental work to be intimately related to his mechanical philosophy. Its central claim is that the mechanical philosophy has a heuristic structure that motivates and gives direction to Boyle's experimental programme. Boyle was able to delimit the scope of possible explanations of any phenomenon by positing both that all qualities are ultimately reducible to a select group of mechanical qualities and that all explanations of natural phenomena (...) are to be in terms of the operations of machines and are to appeal only to qualities that are already familiar. This is illustrated by his investigations into the Torricellian experiment. Boyle's explanation of the elevation of the mercurial cylinder by appeal to the spring of the air was an intermediate mechanical explanation. Boyle was convinced that the spring of the air was ultimately reducible to the mechanical qualities. This in turn had implications for his research into the cause of respiration. In a move that was both parsimonious and consistent with the broad requirements of the mechanical philosophy, Boyle was able to solve the problem of the cause of the inflow of air into the lungs by appeal to his research in pneumatics. This application of a mechanical explanation in pneumatics to physiology is just what one would expect if the mechanical philosophy was as universal as Boyle claimed it to be. Therefore, far from Boyle's experiments having a life of their own, they were clearly directed by and understood in terms of the mechanical philosophy.Keywords: Air-pump; Boyle; Chalmers; Experiment; Explanation; Mechanism.

This paper argues that the construction of natural histories, as advocated by Francis Bacon, played a central role in John Locke's conception of method in natural philosophy. It presents new evidence in support of John Yolton's claim that "the emphasis upon compiling natural histories of bodies ... was the chief aspect of the Royal Society's programme that attracted Locke, and from which we need to understand his science of nature". Locke's exposure to the natural philosophy of Robert Boyle, the medical (...) philosophy of Thomas Sydenham, his interest in travel literature and his conception of the division of the sciences are examined. From this survey, a cumulative case is presented which establishes, independently of an in-depth exegesis of his Essay Concerning Human Understanding, the central role for Locke of the construction of natural histories in natural philosophy.

This collection presents the first sustained examination of the nature and status of the idea of principles in early modern thought. Principles are almost ubiquitous in the seventeenth and eighteenth centuries: the term appears in famous book titles, such as Newton’s _Principia_; the notion plays a central role in the thought of many leading philosophers, such as Leibniz’s Principle of Sufficient Reason; and many of the great discoveries of the period, such as the Law of Gravitational Attraction, were described as (...) principles. Ranging from mathematics and law to chemistry, from natural and moral philosophy to natural theology, and covering some of the leading thinkers of the period, this volume presents ten compelling new essays that illustrate the centrality and importance of the idea of principles in early modern thought. It contains chapters by leading scholars in the field, including the Leibniz scholar Daniel Garber and the historian of chemistry William R. Newman, as well as exciting, emerging scholars, such as the Newton scholar Kirsten Walsh and a leading expert on experimental philosophy, Alberto Vanzo. _The Idea of Principles in Early Modern Thought_ charts the terrain of one of the period’s central concepts for the first time, and opens up new lines for further research.

Early modern experimental philosophers were opposed to speculation, and yet many endorsed speculative theories. This chapter gives a partial explanation of why this is so, using Robert Boyle’s acceptance and promotion of the corpuscular philosophy as a case study. It argues that, in addition to furnishing experimental evidence for the corpuscular hypothesis in his Forms and Qualities, Boyle attempted to establish its epistemic superiority over other speculative theories on the grounds that it is founded upon superior principles. In his ‘Excellency (...) and Grounds of the Mechanical Hypothesis’, Boyle claims that the principles of the corpuscular philosophy are more intelligible, more parsimonious, ontologically primary, simpler and more comprehensive than those of its rivals. On grounds of comparative plausibility then, according to Boyle, the corpuscular philosophy is eminently preferable to its rivals. The final section of the chapter traces the legacy of Boyle’s appraisal of the epistemic status of the corpuscular philosophy in the writings of many of his compatriots from the mid-1660s to the Cyclopedia of Ephraim Chambers of 1728.

This paper argues that, while Locke’s unstable usage of the term ‘mind’ prevents us from claiming that he had a theory of mind, it can still be said that he made a contribution to the philosophy of mind in its contemporary sense. After establishing that it was the term ‘soul’ that predominated in early modern British philosophy, the paper turns to Locke’s three central notions of the soul, the understanding, and the person. It is argued that there are two stages (...) to the development of Locke’s view of the soul: a first philosophical stage and a later theological stage. The first stage is characterized by the application of the material/immaterial distinction. The second stage rejects the utility of this distinction. The two stages are not, however, incompatible, for the bridge between them is found in Locke’s conceptions of the understanding and personhood. While the latter theological stage was, in the end, of the greatest concern to Locke, it is in the earlier philosophical stage that we find his real contribution to what we now call the philosophy of mind.

This paper presents a comprehensive study of Robert Boyle’s writings on seminal principles or seeds. It examines the role of seeds in Boyle’s account of creation, the generation of plants and animals, spontaneous generation, the generation of minerals and disease. By an examination of all of Boyle’s major extant discussions of seeds it is argued that there were discernible changes in Boyle’s views over time. As the years progressed Boyle became more sceptical about the role of seminal principles in the (...) generation of minerals and he came to reject the spontaneous generation of insects and animals from putrefying matter. It is also argued that Boyle’s notion of a generative or ‘plastick’ principle creates a tension within his mechanical philosophy. He appeals to a plastick power in order to explain those phenomena of generation that are beyond the explanatory resources of the corpuscular hypothesis. However, when pressed to explain the nature of this power he either hints, somewhat paradoxically, that it too can be explained mechanically or admits his nescience. (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.

This collection of new essays on John Locke's philosophy provides the most up-to-date entrée into the exciting developments taking place in the study of one of the most important contributors to modern thought.

Two medical essays in the hand of John Locke survive amongst the Shaftesbury Papers in the National Archives (National Archives PRO 30/24/47/2, ff. 31r–38v and ff. 49r–56r). Since the 1960s their authorship has been disputed. Some scholars have attributed them to the London physician Thomas Sydenham, others have attributed them to Locke. Detailed analyses of their contents and the context of their composition provide very strong evidence for Lockean authorship. This is reinforced by the application of the most recent techniques (...) of computational stylistics. (shrink)
