Section 17 of Leibniz’s Monadology contains a famous argument in which considerations of what it would be like to enter a machine that was as large as a mill are offered as reasons to reject materialism about the mental. In this paper, I provide a critical discussion of Leibniz’s mill argument, but, unlike most treatments, my discussion will focus on texts other than the Monadology in which considerations of the mill also appear. I provide a survey of three previous interpretations (...) of the argument and a partial defence of one of them, namely the one that Marc Bobro and I offered in Stepping Back Insider Leibniz's Mill (The Monist, 1998). However, I also argue that a fourth interpretation is necessary to account for the appearances of Leibniz’s mill in at least some of his writings. (shrink)

LEIBNIZ AND THE TWO SOPHIES is a critical edition of all of the philosophically important material from the correspondence between the philosopher Gottfried Wilhelm Leibniz (1646-1716) and his two royal patronesses, Electress Sophie of Hanover (1630-1714), and her daughter, Queen Sophie Charlotte of Prussia (1668-1705). In this correspondence, Leibniz expounds in a very accessible way his views on topics such as the nature and operation of the mind, innate knowledge, the afterlife, ethics, and human nature. The correspondence also contains the (...) only known philosophical writings by Sophie and Sophie Charlotte, and thus provides a valuable insight into their views and concerns, as well as throwing light on their characters. The texts are accompanied by a substantial introductory essay which sets the context for the correspondence and analyzes its main philosophical themes. (shrink)

Leibniz's mill argument in 'Monadology' 17 is a well-known but puzzling argument against materialism about the mind. I approach the mill argument by considering other places where Leibniz gave similar arguments, using the same example of the machinery of a mill and reaching the same anti-materialist conclusion. In a 1702 letter to Bayle, Leibniz gave a mill argument that moves from his definition of perception (as the expression of a multitude by a simple) to the anti-materialist conclusion. Soon afterwards, in (...) the Preface to the New Essays, Leibniz gave a different mill argument. That argument depends upon there being no arbitrary and inexplicable connections in nature, because God would not create such things. Later, in the 'Monadology', Leibniz again used the mill example in arguing against materialism. That passage too, I argue, uses an argument from inexplicability rather than from Leibniz's definition of perception. (shrink)

Drawing on remarks scattered through his writings, I argue that Leibniz has a highly distinctive and interesting theory of color. The central feature of the theory is the way in which it combines a nuanced subjectivism about color with a reductive approach of a sort usually associated with objectivist theories of color. After reconstructing Leibniz's theory and calling attention to some of its most notable attractions, I turn to the apparent incompatibility of its subjective and reductive components. I argue that (...) this apparent tension vanishes in light of his rejection of a widely accepted doctrine concerning the nature of bodies and their geometrical qualities. (shrink)

In the early years of the eighteenth century Leibniz had several interactions with John Toland. These included, from 1702 to 1704, discussions of materialism. Those discussions culminated with the consideration of Toland's 1704 Letters to Serena, where Toland argued that matter is necessarily active. In this paper I argue for two main theses about this exchange and its consequences for our wider understanding. The first is that, despite many claims that Toland was at the time of Letters to Serena a (...) Spinozist, we can make better sense of him as a sort of Hobbesian materialist. The second main point concerns reasons for materialism, and in particular a story Locke tells in the Essay about materialists' motives. Toland defends his materialism by arguing that matter is active, and argues that matter is active by using a conceivability argument. But this is not the crude conceivability argument that Locke suggests motivates materialists. This (together with reflecting on some of Hobbes's arguments) suggests that we might well tell a Lockean story about reasons for early modern materialism, but not Locke's story. (shrink)

This volume contains more than 60 original translations of papers written by the German philosopher Gottfried Wilhelm Leibniz (1646-1716). As well as contributing to Leibniz scholarship, it is intended to function as an introductory text for students.

For the uninitiated, there are two major tendencies in the modeling of human cognition. The older, tradtional school believes, in essence, that full human cognition can be modeled by dividing the world up into distinct entities -- called __symbol s__-- such as “dog”, “cat”, “run”, “bite”, “happy”, “tumbleweed”, and so on, and then manipulating this vast set of symbols by a very complex and very subtle set of rules. The opposing school claims that this system, while it might be good (...) at concluding that Paris is the capital of France or that there must be blood flowing in the left-rear leg of a cow, can never capture the full measure -- indeed, the essence -- of human cognition. For them, the essential features of cognition emerge from the combined effects of myriad, tiny actions far below the surface of consciousness. This is the camp to which Paul Churchland belongs.

In the absence of any plausible reductionist account of consciousness in nonmentalistic terms, the HOT theory says that the best explanation for what makes a mental state conscious is that it is accompanied by a thought (or awareness) that one is in that state. I discuss HOT theory with special attention to how Leibnizian theses can help support it and how it can shed light on Leibniz's theory of perception, apperception, and consciousness. It will become clear how treating Leibniz as (...) a HOT theorist can solve some of the problems he faced and some of the puzzles posed by commentators, e.g. animal mentality and the role of reason and memory in self-consciousness.

Le principe de l’identité des indiscernables constitue l’un des aspects essentiels de la métaphysique leibnizienne de la substance. Il implique notamment que toute substance s’individualise par la totalité infinie de ses propriétés. Sur le plan épistémologique, ce principe pose toutefois problème: comment un entendement fini parvient-il à se représenter les individus, sachant que seul l’entendement de Dieu possède la capacité de connaître la série infinie des propriétés qui individualise la substance? L’auteur vise ici un double objectif : d’une part, démontrer (...) qu’il existe chez Leibniz une philosophie de la connaissance suffisamment distincte des autres disciplines, notamment de la logique et de la métaphysique. D’autre part, examiner l’impact de cette épistémologie sur la théorie de l’individuation. Il s’agit d’analyser les différents moyens employés par Leibniz pour expliquer la conception des êtres individuels du point de vue de la représentation humaine. (shrink)

Leibniz’s reasons for rejecting materialism are complex and often rely on assumptions that are deeply puzzling to contemporary philosophers. However, the discussion of these issues in § 17 of the Monadology has received a lot of attention over the past couple of decades. For it is here that Leibniz presents the most well known version of his “mill argument.”.

I consider Leibniz's thoughts about Hobbes's materialism, focusing on his less-discussed later thoughts about the topic. Leibniz understood Hobbes to have argued for his materialism from his imagistic theory of ideas. Leibniz offered several criticisms of this argument and the resulting materialism itself. Several of these criticisms occur in texts in which Leibniz was engaging with the generation of British philosophers after Hobbes. Of particular interest is Leibniz's correspondence with Damaris Masham. Leibniz may have been trying to communicate with Locke, (...) but ended up discussing Masham's version of the argument for materialism that Leibniz attributed to Hobbes. (shrink)

In his well-known Discourse on Metaphysics , Leibniz puts individual substance at the basis of metaphysical building. In so doing, he connects himself to a venerable tradition. His theory of individual concept, however, breaks with another idea of the same tradition, that no account of the individual as such can be given. Contrary to what has been commonly accepted, Leibniz’s intuitions are not the mere result of the transcription of subject-predicate logic, nor of the uncritical persistence of some old metaphysical (...) assumptions. They grow, instead, from an unprejudiced inquiry about our basic ontological framework, where logic of truth, linguistic analysis, and phenomenological experience of the mind’s life are tightly interwoven. Leibniz’s struggle for a concept capable of grasping concrete individuals as such is pursued in an age of great paradigm changes – from the Scholastic background to Hobbes’s nominalism to the Cartesian ‘way of ideas’ or Spinoza’s substance metaphysics – when the relationships among words, ideas and things are intensively discussed and wholly reshaped. This is the context where the genesis and significance of Leibniz’s theory of ‘complete being’ and its concept are reconstrued. The result is a fresh look at some of the most perplexing issues in Leibniz scholarship, like his ideas about individual identity and the thesis that all its properties are essential to an individual. The questions Leibniz faces, and to which his theory of individual substance aims to answer, are yet, to a large extent, those of contemporary metaphysics: how to trace a categorial framework? How to distinguish concrete and abstract items? What is the metaphysical basis of linguistic predication? How is trans-temporal sameness assured? How to make sense of essential attributions? In this ontological framework Leibniz’s further questions about the destiny of human individuals and their history are spelt out. Maybe his answers also have something to tell us. This book is aimed at all who are interested in Leibniz’s philosophy, history of early modern philosophy and metaphysical issues in their historical development. (shrink)

This work represents an investigation of the most important properties of the human mind consciousness, apperception and reflection - and of their significance for Leibnizian philosophy. The development of Leibniz's thinking in the course of his treatment of these themes receives especially detailed treatment, and is thoroughly documented on the basis of the original texts. The concepts of consciousness and reflection were the object of intensive discussion in the l7th century. Starting out from the problem of the distinction between humans (...) and brutes - Descartes' view of animals as mere machines was always decisively rejected by Leibniz-Kulstad shows the significance of these concepts in the early writings of Leibniz. He shows how Leibniz was then stimulated by Locke to add the word "apperception" into his philosophy. The author sets out the influence of Locke on Leibniz and demonstrates how Leibniz adopted a firmer and more constant position as to the relation between consciousness and reflection than one finds in Locke's own writings. From the beginning to the end of his life Leibniz defends the thesis that both consciousness and reflection consist in the memory of one mental act via another. The author shows how Leibniz hereby aligns himself with an European philosophihical tradition which can be traced back to Plato, Aristotle and Aquinas. Of course, a clarification of the meanings of words such as "consciousness", "reflection" and "apperception" is important not only for an understanding of Leibniz's philosophy but also for contemporary metaphysics and theory of knowledge. Leibniz certainly recognized and thought through the problems associated with these words, but he never developed a final, coherent theory, a fact which certainly reflects in part the complexity of the underlying problems. By exploiting not only all the relevant Leibnizian writings but also the results of more receent philosophy in this field, Kulstad is able to draw a reliable picture both of Leibniz's treatment of these problems and of the influence of his views on his contemporaries and successors.

The Light of the Soul examines the debate between Leibniz, Malebranche, and Descartes on the nature of ideas, which was crucial to the development of early modern thinking about the mind and knowledge. Nicholas Jolley guides the reader through the debate and considers its implications for a broad range of issues, such as innate ideas, self-knowledge, scepticism, the mind-body problem, and the creation of the eternal truths, which are as important to philosophy today as they were in the seventeenth century.

This is the most up-to-date and comprehensive interpretation of the philosophy of Gottfried Wilhelm Leibniz. Amongst its other virtues, it makes considerable use of unpublished manuscript sources. The book seeks to demonstrate the systematic unity of Leibniz's thought, in which theodicy, ethics, metaphysics and natural philosophy cohere. The key, underlying idea of the system is the conception of nature as an order designed by God to maximise the opportunities for the exercise of reason. From this idea emerges the view that (...) this world is the best of all possible worlds, and an ethical ideal in which the well-being of human beings is promoted through the gradual extension of intellectual enlightenment.

Seeking to rediscover the connection between philosophy as studied in universities and those general views of man and reality which are 'philosophy' to the educated layman, Edward Craig here offers a view of philosophy and its history since the early seventeenth century. He presents this period as concerned primarily with just two visions of the essential nature of man. One portrays human beings as made in the image of God, required to resemble him as far as lies in our power; (...) the other sees us as autonomous creators of our own environment and values. The author writes with a broad sweep not encouraged by recent fashion, yet shows how textual detail which previous commentators have found opaque becomes transparent when viewed against such a background. In the final chapter he treats passages from recent work in the same way. The general conceptions which philosophical thought embodies can equally well be embodied in other media, especially literary. The author illustrates this point with German and English examples and thereby draws together disciplines often felt to be far apart. He also reveals striking similarities between Anglo-American and certain twentieth-century continental European lines of thought. (shrink)

Explores the understanding of self-consciousness and personal identity - two fundamendtal features of human subjectivity - as it developed in early modern philosophy. Udo Thiel presents a critical evaluation of these features as they were conceived in the sevententh and eighteenth centuries. He explains the arguments of thinkers such as Descartes, Locke, Leibniz, Wolff, and Hume, as well as their early critics, followers, and other philosophical contemporaries, and situates them within their historical contexts. Interest in the issues of self-consciousness and (...) personal identity is in many ways characteristic [of] and even central to early modern thought, but Thiel argues here that this is also an interest that continues to this day, in a form still strongly influenced by the conceptual frameworks of early modern thought. In this book he attempts to broaden the scope of the treatment of these issues considerably, covering more than a hundred years of philosophical debate in France, Britain, and Germany while remaining attentive to the details of the arguments under scrutiny and discussing alternative interpretations in many cases"--Publisher's description, p.

Leibniz argumentiert in der Monadologie, daß das Bewußtsein nicht auf rein mechanische und materielle Prozesse reduziert werden kann. Diesem wohlbekannten Argument wird bisweilen ein elementarer Trugschluß der Zusammensetzung vorgeworfen. Meiner Meinung nach hingegen weist dieses Argument eher auf ein grundlegendes Problem in unserem physikalischen Verständnis des menschlichen Geistes hin, einem Verständnis, das auch heute noch akzeptiert wird. Ich zeige jedoch weiterhin, daß Leibniz nicht erkannt hat, daß sein Argument die Möglichkeit offen läßt, daß es unsere begrifflichen Grenzen sind, die uns (...) daran hindern, das Bewußtsein durch materielle Prozesse zu verstehen.

Leibniz raises three main objections to the doctrine of occasionalism: (1) it is inconsistent with the supposition of finite substances; (2) it presupposes the occurrence of "perpetual miracles"; (3) it requires that God "disturb" the ordinary laws of nature. At issue in objection (1) is the proper understanding of divine omnipotence, and of the relationship between the power of God and that of created things. I argue that objections (2) and (3), on the other hand, derive from a particular conception (...) of the intelligibility of nature, a conception to which Leibniz is firmly committed and that occasionalists like Malebranche no less firmly reject.

Gottfried Wilhelm Leibniz (1646-1716) was hailed by Bertrand Russell as "one of the supreme intellects of all time." A towering figure in Seventeenth century philosophy, his complex thought has been championed and satirized in equal measure, most famously in Voltaire's Candide. In this outstanding introduction to his philosophy, Nicholas Jolley introduces and assesses the whole of Leibniz's philosophy. Beginning with an introduction to Leibniz's life and work, he carefully introduces the core elements of Leibniz's metaphysics: his theories of substance, identity (...) and individuation; monads and space and time; and his important debate over the nature of space and time with Newton's champion, Samuel Clarke. He then introduces Leibniz's theories of mind, knowledge, and innate ideas, showing how Lenin anticipated the distinction between conscious and unconscious states, before examining his theory of free will and the problem of evil. An important feature of the book is its introduction to Leibniz'smoral and political philosophy, an overlooked aspect of his work. The final chapter assesses legacy and the impact of his philosophy on philosophy as a whole, particularly on the work of Immanuel Kant. Throughout, Nicholas Jolley places Lenin in relation to some of the other great philosophers, such as Descartes, Spinoza and Locke, and discusses Leibniz's key works, such as the Monadology and Discourse on Metaphysics.

According to Leibniz's late metaphysics, sensory perception represents to us as extended, colored, textured, etc., a world which fundamentally consists only of non-spatial, colorless entities, the monads. It is a short step from here to the conclusion that sensory perception radically misleads us about the true nature of reality. In this paper, I argue that this oft-repeated claim is false. Leibniz holds that in typical cases of body perception the bodies perceived really exist and have the qualities, both primary and (...) secondary, they are perceived to have. At the same time, Leibniz holds that our perceptions of these bodies are accurate representations of the monads from which the bodies result. The contrary thesis — that our body perceptions are misrepresentations of the monads — stems from a misunderstanding of Leibniz's theory of confused concepts and his phenomenalist account of the nature of body. Clarifying these issues will have important consequences for our understanding of Leibniz's idealistic metaphysics and the manner in which that metaphysical theory is meant to support mechanistic science.

Seventeenth century discussions of materialism, whether favorable or hostile towards the position, are generally conducted on a level of much less precision and sophistication than recent work on the problem of the mind-body relation. Nevertheless, the earlier discussions can still be interesting to philosophers, as the plethora of references to Cartesian arguments in the recent literature makes clear. Certainly the early development of materialist patterns of thought, and efforts on both the materialist and immaterialist side to establish fundamental points in (...) the philosophical analysis of mind, have considerable historical interest at the present time. This paper attempts to clarify the significance of some of leibniz's views in connection with the materialist thesis. I do not have in mind his rather notorious parallelism, though some of the points made below bear indirectly on the character of this position. Instead, I will examine his approach to arguments against materialism. (shrink)

"We are omniscient but confused," says Leibniz. He also says that we live in the best of all possible worlds, yet do not causally interact. So what are we? Leibniz is known for many things, including the ideality of space and time, calculus, plans for a universal language, theodicy, and ecumenism. But he is not known for his ideas on the self and personal identity. This book shows that Leibniz offers an original, internally coherent theory of personal identity, a theory (...) that stands on its own even next to Locke's contemporaneous and more famous version. This book will appeal not only to students of Leibniz's thought but also to philosophers and psychologists interested in methodological problems in understanding or formulating theories of self and personal identity.
