This paper examines a widely accepted reading of monads as the most fundamental elements of reality. Garber [Leibniz – Body, Substance, Monad, Oxford: Oxford University Press, 2009] argues that simple monads – seen as mind-like atoms without parts and extension – replace the corporeal substance of Leibniz’s middle period. Phemister [Leibniz and the Natural World – Activity, Passivity and Corporeal Substances in Leibniz’s Philosophy, Dordrecht: Springer, 2005] argues that monads figure also at the top as complete corporeal substances. Building on (...) Fichant [‘L’invention métaphysique’ in G.W. Leibniz, Discours de métaphysique suivi de Monadologie et autres textes, edited by Michel Fichant, Paris: Gallimard, 2004], I argue that, for Leibniz, monads function not only as building blocks at the bottom level of composition but also at the top, as grounding the unity and hence the being of complete substances and organic unities. Since organic unities or living beings are seen by Leibniz as natural machines with a nested structure, and since monads are likened to living beings, this would imply that the use of the concept ‘monad’ holds not only at the bottom, and not only at the top, but all over the range between them.

According Leibniz's thesis of universal expression, each substance expresses the whole world, i.e. all other substances, or, as Leibniz frequently states, from any given complete individual notion (which includes, in internal terms, everything truly attributable to a substance) one can "deduce" or "infer" all truths about the whole world. On the other hand, in Leibniz's view each (created) substance is internally individuated, self-sufficient and independent of other (created) substances. What may be called Leibniz's expression problem is, how to reconcile these (...) views with each other, that is, how a substance that expresses the whole world, even in the sense that the whole world can be "inferred" from its complete individual notion, can be self-sufficient and internally individuated. The purpose of this paper is to give an exact account of this tricky problem of universal expression, an account that retains substances' self-sufficiency under the constraint that all truths about the whole world are to be obtained from complete individual notions. It will also be shown how the explication of universal expression to be given accounts for Leibniz's thesis of universal change, i.e. the view that any change in any substance is reflected as a real, internal change in each and every other substance.

According to the standard view of his metaphysics, Leibniz endorses idealism: the thesis that the world is made up solely of minds or monads and their perceptual and appetitive states. Recently,this view has been challenged by some scholars, who argue that Leibniz can be seen as admitting corporeal substances, that is, animals or embodied souls, into his ontology, and that, therefore, it is false to attribute a strict idealism to him. Subtler accounts suggest that Leibniz begins his philosophical career as (...) an advocate of (some form of) the modern ‘mechanical’ philosophy and ends his career as an idealist, raising the issue when and why Leibniz adopts his monadological metaphysics. This article argues that, given a constellation of metaphysical, logical, and theological views, Leibniz is committed to the ontological primacy of mind or form even in his ‘middle years’. (shrink)

Gottfried Wilhelm Leibniz (1646–1716) was one of the great thinkers of the seventeenth and eighteenth centuries and is known as the last “universal genius”. He made deep and important contributions to the fields of metaphysics, epistemology, logic, philosophy of religion, as well as mathematics, physics, geology, jurisprudence, and history. Even the eighteenth century French atheist and materialist Denis Diderot, whose views could not have stood in greater opposition to those of Leibniz, could not help being awed by his achievement, writing (...) in his Encyclopedia, “Perhaps never has a man read as much, studied as much, meditated more, and written more than Leibniz… What he has composed on the world, God, nature, and the soul is of the most sublime eloquence. If his ideas had been expressed with the flair of Plato, the philosopher of Leipzig would cede nothing to the philosopher of Athens.” (Vol. 9, p. 379) Indeed, Diderot's mood was almost despairing in a remark from another piece, which also has a great deal of truth in it: “When one compares the talents one has with those of a Leibniz, one is tempted to throw away one's books and go die quietly in the dark of some forgotten corner.” More than a century later, Gottlob Frege, who fortunately did not cast his books away in despair, expressed similar admiration, declaring that “in his writings, Leibniz threw out such a profusion of seeds of ideas that in this respect he is virtually in a class of his own.” (“Boole's logical Calculus and the Concept script” in Posthumous Writings , p. 9) The aim of this entry is primarily to introduce Leibniz's life and summarize and explicate his views in the realms of metaphysics, epistemology, philosophical theology, and natural philosophy.

The monad, of which we will speak here, is nothing else than a simple substance, which goes to make up compounds; by simple, we mean without parts. From its origins in antiquity the monad is a concept that has time and again beguiled and attracted philosophers. This thesis will argue that it is a concept that lives on in the work of Bruno Latour and that it continues to have a contemporary relevance, offering a way out of sterile debates rooted (...) in Cartesian dualism – subject/object, interior/exterior, essence/accident, whole/part, mind/body – and an alternative to those traditions which privilege one side of the dualism over the other – positivism on one hand, postmodernism on the other. The present study charts the development of the monad through the modern period, beginning with the work of Gottfried Leibniz and, thereafter, its recurrence in the work of Gabriel Tarde, Alfred North Whitehead, and, finally, Bruno Latour. However, rather than simply sketching a chronological history of the monad this study takes as its starting point Bruno Latour’s Actor-Network Theory, or to use Latour’s preferred formulation, Actant Rhizome Ontology. Arguing that Latour’s work is best understood as being another instance of a monadological metaphysics that – contra Graham Harman – owes more to Whitehead than Heidegger, to Tarde than Nietzsche, to Leibniz than Spinoza; the thesis traces the genetic intellectual relations between Latour and his three co-monadologists. Latour himself frequently identifies Leibniz, Tarde and Whitehead as intellectual antecedents in his own work; in the spirit of Latour’s own Actor-Network Theory, this thesis takes a closer look at these claimed chains of association. The first chapter surveys Leibniz’s monadology and argues that, far from being an idealist, Leibniz was committed to a monism that recognized the materiality of simple substance through his corporeal ‘de Volder’ monad. This does not necessarily lead, as argued forcibly Pauline Phemister, to pan-psychism, as Leibniz anticipates William James’ ‘depsychologized’ category of experience with his three level system of bare, soul and spirit monads, where only the spirit monads possess anything resembling a mind; however, it takes Whitehead’s transformation of the monad into the actual entity to complete the break between experience and mind. The second chapter provides a close reading of Gabriel Tarde’s Monadology & Sociology, a work only made available in English in 2012. Latour has played a significant role in the rediscovery of Tarde, claiming his criminologist compatriot as an intellectual forefather; yet throughout the 20th century Tarde’s work quietly influenced continental philosophy through Giles Deleuze who, despite only ever mentioning Tarde parenthetically, borrows Tarde’s very own formulation for the title of Difference et Repetition. The chapter presents Tarde’s work as being an explosion of the Leibnizian monad where the universe is no longer reflected but literally embodied in each individual entity while at the same time diffused through the universe of monads by virtue of relations of possession. Taken together with his theory of repetition and imitation, his privileging of difference over identity, and his philosophy of having – his ‘echontology’ – Tarde’s monadology provides the foundations for a truly relational ontology; foundations which Latour will retrospectively claim for Actor Network Theory. The third chapter considers Whitehead’s metaphysical scheme as presented in Process and Reality. Whitehead resolves the ‘audacious fudge’ committed by Leibniz – the doctrine of pre-established harmony – through a complex and sophisticated realist metaphysical system, one held together by ‘creativity’. Whitehead’s categoreal scheme, his peculiar vocabulary, his reiterative method whereby ideas are presented over and over again in different contexts mirror the very metaphysical scheme he describes. This – along with his insistence on the atomic nature of time and the instantaneous emergence and realization of each ‘actual entity’ – lays the basis for Latour’s democratic ontology which, as well as famously according equality between human and non-human actors affords concepts the same ontological status as the thinker in whose mind they have been formed. The final chapter returns to the work of Latour himself to find the monad reassembled as the ‘actor-network’. Latour’s ontological scheme is discussed in detail with reference to his three antecedents, and his ontology is presented as a reiteration/renewal of the monad; an ontology that itself demands to be renewed each and every time it is deployed. Finally, the thesis argues that Latour pays insufficient heed to Whitehead’s understanding of abstraction with the result that, despite developing the idea himself, Latour fails to fully embrace the ontological reality of the abstract. This in turn leads to his preference for litany over critique and results in a philosophy with a great deal of descriptive power but little or no transformational power. The ‘compositionist’ politics that emerge from Latour’s Actant Rhizome Ontology are ambiguous and utopian, and the thesis concludes by suggesting that more work is required to further Latour’s democratization of the monad, to include its radicalization, in pursuit of a monadology that provides an ontological basis for: …the genuine resolution of the conflict between man [sic] and nature and between man and man – the true resolution of the strife between existence and essence, between objectification and self-confirmation, between freedom and necessity, between the individual and the species.

I argue for three main claims about Leibniz. (1) He views representation as a kind of structural correspondence between the representing thing and its target. (2) The primary sense in which he considers a perception or representation distinct, as opposed to confused, concerns the degree to which its structure is explicit or consciously accessible. (3) This is also the sense in which he takes concepts or ideas to be distinct.
