Though it did not yet exist as a discrete field of scientific inquiry, biology was at the heart of many of the most important debates in seventeenth-century philosophy. Nowhere is this more apparent than in the work of G. W. Leibniz. In Divine Machines, Justin Smith offers the first in-depth examination of Leibniz's deep and complex engagement with the empirical life sciences of his day, in areas as diverse as medicine, physiology, taxonomy, generation theory, and paleontology. He shows how these (...) wide-ranging pursuits were not only central to Leibniz's philosophical interests, but often provided the insights that led to some of his best-known philosophical doctrines.Presenting the clearest picture yet of the scope of Leibniz's theoretical interest in the life sciences, Divine Machines takes seriously the philosopher's own repeated claims that the world must be understood in fundamentally biological terms. Here Smith reveals a thinker who was immersed in the sciences of life, and looked to the living world for answers to vexing metaphysical problems. He casts Leibniz's philosophy in an entirely new light, demonstrating how it radically departed from the prevailing models of mechanical philosophy and had an enduring influence on the history and development of the life sciences. Along the way, Smith provides a fascinating glimpse into early modern debates about the nature and origins of organic life, and into how philosophers such as Leibniz engaged with the scientific dilemmas of their era.

Knowledge of the responsibilities of engineers is the foundation for answering ethical questions about the work of engineers. This paper defines the responsibilities of engineers by considering what constitutes the nature of engineering as a particular form of activity. Specifically, this paper focuses on the ethical responsibilities of engineers qua engineers. Such responsibilities refer to the duties acquired in virtue of being a member of a group. We examine the practice of engineering, drawing on the idea of practices developed by (...) philosopher Alasdair MacIntyre, and show how the idea of a practice is important for identifying and justifying the responsibilities of engineers. To demonstrate the contribution that knowledge of the responsibilities of engineers makes to engineering ethics, a case study from structural engineering is discussed. The discussion of the failure of the Sleipner A Platform off the coast of Norway in 1991 demonstrates how the responsibilities of engineers can be derived from knowledge of the nature of engineering and its context.

Many today agree that philosophy, as an academic discipline, must, for the sake of its very survival, become more inclusive of a wider range of perspectives, coming from a more diverse pool of philosophers. Yet there has been little serious reflection on how our very idea of what philosophy is might be preventing this change from taking place. In this essay I would like to consider the ways in which our ideas about philosophy's relation to tradition, and its relation to (...) other dimensions of human culture, influence efforts to promote greater diversity in the field.

This volume collects contributions from leading scholars of early modern philosophy from a wide variety of philosophical and geographic backgrounds. The distinguished contributors offer very different, competing approaches to the history of philosophy.

Other than the historical writings, the edition of which has yet to begin, Series VIII of the Academy Edition of Leibniz’s writings, presenting his “natural-scientific, medical, and technical” contributions, has been, since the project began in 1923, consistently deemed to be of low priority, and it is only very recently that the project has got fully underway. Coming, as it does, nearer to the end of the edition of the complete works, Series VIII has the advantage of accumulating some of (...) the ‘run-off’ of the philosophical writings, that is, texts of philosophical import that for whatever reason were not initially deemed sufficiently philosophical to be included in Series II or VI. Currently in preparation are the writings on chemistry, hydrology, and other natural sciences. The medical and ‘biological’ manuscripts, identified as ‘LH III’, will be edited likely some years from now.2 On our reading of these manuscripts, all or most are of at least some interest to the scholar of Leibniz’s philosophy.

I argue against the view that Leibniz’s construction of reality out of perceiving substances must be seen as the first of the modern idealist philosophies. I locate this central feature of Leibniz’s thought instead in a decidedly premodern tradition. This tradition sees bodiliness as a consequence of the confused perception of finite substances, and equates God’s uniquely disembodied being with his maximally distinct perceptions. But unlike modern idealism, the premodern view takes confusion as the very feature of any created substance (...) that makes possible its distinctness from the Creator. Modern idealism, in contrast, emerges when the external world becomes a problem, when the epistemological worry arises as to how the mind might access it. In the tradition in which I place Leibniz, there simply is no such worry. (shrink)

In diesem Artikel bringe ich zwei Thesen vor. Zum einen behaupte ich, daβ in den ersten Jahren des 18. Jahrhunderts eine wichtige terminologische Wende in der Leibnizschen Metaphysik stattfand: Das Thema der körperlichen Substanz wurde durch den Begriff des Organismus ersetzt. Die Entdeckung dieser Wende widerspricht der weit verbreiteten Meinung, Leibniz habe -vom Briefwechsel mit Des Bosses hier abgesehen -in seinen letzten Jahren das Interesse an einer Theorie der zusammengesetzten Einheiten verloren und stattdessen seinen früheren idealistischen Glauben, daß es nur (...) einfache Substanzen gibt, bis zum Ende seines Lebens verteidigt. Zum zweiten vermute ich, daß die Realität der zusammengesetzten Entitäten, die aus der unio von Seele und Körper entsteht, durch die Lehre der prästabilierten Harmonie begründet wird -aufgrund der in meiner Dissertation verteidigten Auffassung, daβ diese Lehre von der Mikroskopie der Leibniz-Zeit inspiriert und gerechtfertigt wird, behaupte ich zudem, daβ Leibniz' spätere Ideen zum ontologischen Status der Körper ebenfalls auf sein Interesse an der Mikroskopie verweisen.

In some very interesting recent work, Peter Fenves has sought to trace G. W. Leibniz's views on human diversity back to the philosopher's core philosophical concerns, in particular to his metaphysical picture of the world as consisting in causally unconnected substances, monads, that are ‘windowless’, ‘worlds apart’. In this article I argue by contrast that Leibniz's anthropological views develop quite independently of his core metaphysics, and are rooted instead in his significant work as a historian and genealogist. In this connection, (...) he develops a conception of race as a ‘series of generations’, and of genealogy as ‘the explication of this series’, that will in turn ground much of his thought about not just human groups, but about living kinds in general. These conceptions, moreover, offer significant new insight into Leibniz's position with respect to the philosophical problem of the ontological status of species. (shrink)

In this short essay I will aim to show that literary fiction is consistently at the vanguard of the exploration of philosophical problems relating to the concept of world, while what we think of as philosophy, in the narrower sense, typically arrives late on the scene, picking up themes that have already been explored in literary texts that are explicitly intended as exercises of the imagination. I will pursue this argument with a sustained investigation of the shared aims and methods (...) of Miguel de Cervantes and René Descartes. (shrink)

This book is a significant accomplishment, and for now the most comprehensive intervention in a debate that has been more than three hundred years in the making. At least since Pierre Bayle, commentators have imagined a sort of paradox in the pairing of Spinoza’s irreproachable way of life with his scandalous philosophy, in contrast with the perfect fit between Leibniz’s optimism for the status quo with his supposedly opportunistic relation to his courtly benefactors. Together with these biographical coordinates, to which (...) Lærke’s work is attentive and sensitive, there is a philosophical opposition that is supposed to be absolute: each philosopher is the other’s perfect opposite. Matthew Stewart’s bestseller The Courtier and the Heretic is the latest iteration of this myth, and Lærke’s study might best be summed up as the perfect antidote to Stewart’s: it is a rigorous, dense, and, most importantly, a just treatment of the authors themselves, whose own words often belie the roles in which they would posthumously be cast. While Lærke acknowledges that there is indeed an easy opposition one can construct between the major metaphysical commitments of the two thinkers, he nonetheless wants to know how their systematic differences might have grown out of an intense engagement on Leibniz’s part with a philosophy he indeed ended up opposing, yet against which he felt compelled to articulate his own views, and back to which he often seemed in danger of returning.

In this article, I consider the significance of the discovery of spermatozoa for Leibniz's deeply held beliefs that (i) no true substance can ever be generated or destroyed, except miraculously; and (ii) that every substance must be perpetually organically embodied. I further consider the way these beliefs are transformed as Leibniz's basic middle-period commitment to corporeal substance gives way (though not entirely) to a metaphysics of monadological immaterialsm. What endures throughout, I show, is the conviction that whatever is real must (...) be indestructible, whether this is conceived as a form-matter compound in which the two components can never be entirely sundered from one another, or as a node of perception “absolutely destitute of parts”. Whatever the deepest metaphysical account of corporeality, Leibniz never abandons his interest in spermatozoa as the corporeal hosts of preexisting animals. (shrink)

Much recent scholarly treatment of the theoretical and practical underpinnings of biological taxonomy from the 16 th to the 18 th centuries has failed to adequately consider the importance of the mode of generation of some living entity in the determination of its species membership, as well as in the determination of the ontological profile of the species itself. In this article, I show how a unique set of considerations was brought to bear in the classification of creatures whose species (...) membership was thought to be entirely determined by descent from parents of the same kind, in contrast with creatures whose generation could proceed spontaneously or through budding. Concretely, the relevance of mode of generation to the practice of taxonomy means that we must rethink the role of the early modern botanists in the development of a universal science of applied taxonomy. I argue that the task of classifying ‘higher’ biological kinds—those united, in Kant’s language, through their generative power—is one with its unique set of problems, arising as much from classical anthropology as from natural philosophy, and that the conception of zoological species that emerged in the early modern period was a consequence of these problems, and not primarily of the ‘applied metaphysics’ of classificatory practice.

This article examines the debate among natural philosophers during the early modern period which concerned whether living beings could be understood as biological machines that did not require a distinct principle of life or soul to explain their complex functioning. It suggests that these innovations can be seen collectively as a gradual substitution of the categorial framework of Aristotle by one derived from the experimental and mathematical sciences. The traditional epistemic relationship between natural philosophy and metaphysics thereby began a long-term (...) reversal. This article also discusses the sources of the early modern machine concept, animal spirits, and the problem of intermediate principles. (shrink)

Dans cet article je mets en évidence quelques problèmes conceptuels importants posés par le prétendu phénomène de la génération spontanée, en montrant comment ils étaient liés historiquement à la question théorique des origines et de l’ontologie des espèces biologiques. Au XVIe et XVIIe siècle tout particulièrement, la possibilité que des formes organiques soient générées dans la matière inorganique supposait la possibilité que le hasard gouverne non seulement l’apparition d’une anguille ou d’une souris, mais qu’il gouverne l’apparition originelle de leurs espèces (...) mêmes. En outre, dans la conception de la reproduction sexuelle que le mécanisme parvient à répandre, toute génération, des êtres humains aussi bien que des anguilles, menace de ne plus s’expliquer autrement que par ce que Descartes appelle « les causes mineures ». Ainsi, comme je tenterai de le prouver, les problèmes théoriques que la génération spontanée, telle que le début de la modernité la concevait, posaient à la compréhension de l’ontologie des espèces, n’étaient pas essentiellement différents de ceux soulevés par l’explication mécaniste de la reproduction sexuelle, et si nous n’accordons pas à ce fait l’attention nécessaire, nous perdons de vue, je pense, un facteur important dans le rejet ultime de la génération spontanée.In this article I shall draw out some of the important conceptual problems posed by the purported phenomenon of spontaneous generation, showing how these problems were historically connected with the theoretical question of the origins and nature of biological species, and above all with the problem of their boundaries. In the 16th- and 17th- centuries in particular, the possibility of organic forms arising from inorganic matter carried with it the possibility that chance governs not only the emergence of an individual eel or mouse, but indeed governs the original emergence of the mouse- and eel-kinds. Moreover, on the newly ascendant mechanist understanding of sexual reproduction, all generation, whether of eels or of horses and men, now threatened to be exhaustively accounted for in terms of what Descartes called ‘minor causes’. Thus, I argue, the sort of problems that spontaneous generation was perceived to bring about for the early modern understanding of the ontology of species were not in principle any different from the problems posed by the mechanist account of sexual reproduction, and if we fail to note this, I show, we overlook an important factor in the eventual demise of spontaneous-generation theory.

This chapter examines the convention concerning the theories of generation and form in the field of natural philosophy in Great Britain during the seventeenth century. It explains that natural philosophers treated the questions of biological generation interchangeably with those coming from chemistry, mineralogy, and meteorology, and considers Antoine Goudin's argument that there are both efficient and final causes at work in the earth's production of rocks that resemble animals or parts of animals. The chapter also suggests that the ‘chymists’ were (...) consistently presented as a challenging third party, alongside Aristotelianism and traditional atomism, in the effort to account for the composition of natural bodies.
