This book reveals a thread that runs through Leibniz’s metaphysics: from his logical notion of possible individuals to his notion of actual, nested ones. It presents Leibniz’s subtle approach to possibility and explores some of its consequential repercussions in his metaphysics. The book provides an original approach to the questions of individuation and relations in Leibniz, offering a novel account of Leibniz’s notion of Nested Individuals.
This volume brings together a number of original articles by leading Leibniz scholars to address the meaning and significance of Leibniz’s notions of compossibility and possible worlds. In order to avoid the conclusion that everything that exists is necessary, or that all possibles are actual, as Spinoza held, Leibniz argued that not all possible substances are compossible, that is, capable of coexisting. In Leibniz’s view, the compossibility relation divides all possible substances into disjoint sets, each of which constitutes a possible world, or a way that God might have created things. For Leibniz, then, it is the compossibility relation that individuates possible worlds; and possible worlds form the objects of God’s choice, from among which he chooses the best for creation. Thus the notions of compossibility and possible worlds are of major significance for Leibniz’s metaphysics, his theodicy, and, ultimately, for his ethics. Given the fact, however, that none of the approaches to understanding Leibniz’s notions of compossibility and possible words suggested to date have gained universal acceptance, the goal of this book is to gather a body of new papers that explore ways of either refining previous interpretations in light of the objections that have been raised against them, or ways of framing new interpretations that will contribute to a fresh understanding of these key notions in Leibniz’s thought.
Gonzalo Rodriguez-Pereyra presents an original study of the place and role of the Identity of Indiscernibles in Leibniz's philosophy. The Principle of the Identity of Indiscernibles rules out numerically distinct but perfectly similar things; Leibniz derived it from more basic principles and used it to establish important philosophical theses. Rodriguez-Pereyra aims to establish what Leibniz meant by the Principle of Identity of Indiscernibles, what his arguments for and from it were, and to assess those arguments and Leibniz's claims about the Principle of Identity of Indiscernibles. He argues that Leibniz had a very strong version of the principle, according to which no possibilia (whether or not they belong to the same possible world) are intrinsically perfectly similar, where this excludes things that differ in magnitude alone. The book discusses Leibniz's arguments for the Identity of Indiscernibles in the Meditation on the Principle of the Individual, the Discourse on Metaphysics, Notationes Generales, Primary Truths, the letter to Casati of 1689, the correspondence with Clarke, as well as the use of the Identity of Indiscernibles in Leibniz's arguments against the Cartesian conception of the material world, atoms, absolute space and time, the Lockean conception of the mind as a tabula rasa, and freedom of indifference. Rodriguez-Pereyra argues that the Identity of Indiscernibles was a central but inessential principle of Leibniz's philosophy.
The Actual and the Possible presents new essays by leading specialists on modality and the metaphysics of modality in the history of modern philosophy from the seventeenth to the twentieth centuries. It revisits key moments in the history of modern modal doctrines, and illuminates lesser-known moments of that history. The ultimate purpose of this historical approach is to contextualise and even to offer some alternatives to dominant positions within the contemporary philosophy of modality. Hence the volume contains not only new scholarship on the early-modern doctrines of Baruch Spinoza, G. W. F. Leibniz, Christian Wolff and Immanuel Kant, but also work relating to less familiar nineteenth-century thinkers such as Alexius Meinong and Jan Lukasiewicz, together with essays on celebrated nineteenth- and twentieth-century thinkers such as G. W. F. Hegel, Martin Heidegger and Bertrand Russell, whose modal doctrines have not previously garnered the attention they deserve. The volume thus covers a variety of traditions, and its historical range extends to the end of the twentieth century, addressing the legacy of W. V. Quine's critique of modality within recent analytic philosophy.
This book presents a comprehensive examination of Gottfried Leibniz's views on the nature of agents and their actions. Julia Jorati offers a fresh look at controversial topics including Leibniz's doctrines of teleology, the causation of spontaneous changes within substances, divine concurrence, freedom, and contingency, and also discusses widely neglected issues such as his theories of moral responsibility, control, attributability, and compulsion. Rather than focusing exclusively on human agency, she explores the activities of non-rational substances and the differences between distinctive types of actions, showing how the will, appetitions, and teleology are key to Leibniz's discussions of agency. Her book reveals that Leibniz has a nuanced and compelling philosophy of action which has relevance for present-day discussions of agency. It will be of interest to scholars and students of early modern philosophy as well as to metaphysicians and philosophers of action.
Embodiment--defined as having, being in, or being associated with a body--is a feature of the existence of many entities, perhaps even of all entities. Why entities should find themselves in this condition is the central concern of the present volume. The problem includes, but also goes beyond, the philosophical problem of body: that is, what the essence of a body is, and how, if at all, it differs from matter. On some understandings there may exist bodies, such as stones or asteroids, that are not the bodies of any particular subjects. To speak of embodiment by contrast is always to speak of a subject that variously inhabits, or captains, or is coextensive with, or even is imprisoned within, a body. The subject may in the end be identical to, or an emergent product of, the body. That is, a materialist account of embodied subjects may be the correct one. But insofar as there is a philosophical problem of embodiment, the identity of the embodied subject with the body stands in need of an argument and cannot simply be assumed. The reasons, nature, and consequences of the embodiment of subjects as conceived in the long history of philosophy in Europe as well as in the broader Mediterranean region and in South and East Asia, with forays into religion, art, medicine, and other domains of culture, form the focus of these essays. More precisely, the contributors to this volume shine light on a number of questions that have driven reflection on embodiment throughout the history of philosophy. What is the historical and conceptual relationship between the idea of embodiment and the idea of subjecthood? Am I who I am principally in virtue of the fact that I have the body I have? Relatedly, what is the relationship of embodiment to being and to individuality? Is embodiment a necessary condition of being? Of being an individual? What are the theological dimensions of embodiment? To what extent has the concept of embodiment been deployed in the history of philosophy to contrast the created world with the state of existence enjoyed by God? What are the normative dimensions of theories of embodiment? To what extent is the problem of embodiment a distinctly western preoccupation? Is it the result of a particular local and contingent history, or does it impose itself as a universal problem, wherever and whenever human beings begin to reflect on the conditions of their existence? Ultimately, to what extent can natural science help us to resolve philosophical questions about embodiment, many of which are vastly older than the particular scientific research programs we now believe to hold the greatest promise for revealing to us the bodily basis, or the ultimate physical causes, of who we really are?
What is possible and why? What is the difference between the merely possible and the actual? In Kants Modal Metaphysics Nicholas Stang examines Kants lifelong engagement with these questions and their role in his philosophical development. This is the first book to trace Kants theory of possibility all theway from the so-called pre-Critical writings of the 1750s and 1760s to the Critical system of philosophy inaugurated by the Critique of Pure Reason in 1781. Stang argues that the key to understanding both the change and the continuity between Kants pre-Critical and Critical theory of possibility is his transformation of the ontological question about possibility-what is it for a being to be possible?-into a question in transcendental philosophy-what is it to represent an object as possible? The first half of Kants Modal Metaphysics explores Kants pre-Critical theory of possibility, including his answer to the ontological question about the nature of possibility, his rejection of the traditional ontological argument for the existence of God, and his own argument that God must exist to ground all possibility. The second half examines why Kant reoriented his theory of possibility around the transcendental question, what this question means, and how Kant answered it in the Critical philosophy. Stang shows that, despite this reorientation, Kants basic scheme for thinking about possibility remains constant from the pre-Critical period through the Critical system. What had been an ontological theory of possible being is reinterpreted, in the Critical system, as a theory of how we must represent possible objects, given the nature of our intellect.
This book explores an overlooked area in Hegel studies: his use of ‘individuality’ (Individualität). Hegel joined a lively conversation, from Leibniz to Romanticism and beyond, about this novel concept/phenomenon. Successive chapters track Hegel’s engagement, in such texts as the Phenomenology, Encyclopedia, and Aesthetics. Hegel’s system tends to follow a syllogistic logic (universal, particular, singular), but ‘individuality’ departs from the norm. The category enacts a certain pragmatics (as against semantics or syntactics) regarding tacit assumptions at work or implicit terms of address, which requires active participation by a thinking subject charged with discerning individuality (which bars resort to explicit rules). The category reflexively implicates the user even in presuming an objective context. ‘Individuality’ should not be confused with ‘individualism,’ wholly distinct in origin. Moreover, Hegel’s Aesthetics embraces a paradoxical anachronism. Like ‘art’ itself, ‘individuality’ emerged as an essentially modern category, though one transferred to the past and to distant cultures.
This volume congregates articles of leading philosophers about potentials and potentiality in all areas of philosophy and the empirical sciences in which they play a relevant role. It is the first encompassing collection of articles on the metaphysics of potentials and potentiality. Potentials play an important role not only in our everyday understanding of objects, persons and systems but also in the sciences. An example is the potential to become an adult human person. Moreover, the attribution of potentials involves crucial ethical problems. Bioethics makes references to the theoretical concept "potential" without being able to clarify its meaning. However, despite its relevance it has not been made subject of philosophical investigation. Mostly, potentials are regarded as a subspecies of dispositions. Whilst dispositions are a flourishing field of research, potentials as such have not come into focus. Potentials like dispositions are modal properties. But already a first glance at the metaphysics of potentials shows that concerning their ascription potentials are more problematic than dispositions since "potential" means that an entity has the potential to acquire a property in the future. Therefore, potentials involve a time structure of the entities in question that is much more complex than those of dispositions. This handbook brings this important concept into focus in its various aspects for the first time. It covers the history of the concept as well as contemporary systematic problems and will be of special interest for philosophers in the fields of general metaphysics, philosophy of science and ethics, especially bioethics. It will also be of interest to scientists and persons concerned with bioethical problems.
Few philosophers have left a legacy like that of Gottfried Wilhelm Leibniz. He has been credited not only with inventing the differential calculus, but also with anticipating the basic ideas of modern logic, information science, and fractal geometry. He made important contributions to such diverse fields as jurisprudence, geology and etymology, while sketching designs for calculating machines, wind pumps, and submarines. But the common presentation of his philosophy as a kind of unworldly idealism is at odds with all this bustling practical activity. In this book Richard. T. W. Arthur offers a fresh reading of Leibniz’s philosophy, clearly situating it in its scientific, political and theological contexts. He argues that Leibniz aimed to provide an improved foundation for the mechanical philosophy based on a new kind of universal language. His contributions to natural philosophy are an integral part of this programme, which his metaphysics, dynamics and organic philosophy were designed to support. Rather than denying that substances really exist in space and time, as the idealist reading proposes, Leibniz sought to provide a deeper understanding of substance and body, and a correct understanding of space as an order of situations and time as an order of successive things. This lively and approachable book will appeal to students of philosophy, as well as anyone seeking a stimulating introduction to Leibniz's thought and its continuing relevance.
