Resumen En este trabajo evaluamos el impacto que la adopción de la relatividad del movimiento tiene en la metafísica de Leibniz. En particular argumentamos que el abandono de la comprensión absolutista del mismo anula su noción juvenil de sustancia corpórea. En primer lugar analizamos cómo entiende Leibniz las nociones de cuerpo y movimiento en el periodo juvenil y defendemos que la comprensión absolutista de este último constituye una piedra angular en su primera concepción de la sustancia corpórea. En segundo lugar (...) exponemos los argumentos leibnizianos a favor de la relatividad del movimiento durante el período parisino y mostramos su repercusión en el concepto juvenil de sustancia corpórea.In this paper we evaluate the impact of Leibniz's defense of relativity of motion on his metaphysics. We argue that the abandonment of the absolutist position makes void his first notion of corporeal substance. First, we analyze Leibniz's conception of body and movement in his youth and explain how the assumption of absolute motion during these years plays a role in his notion of corporeal substance. Second, we examine his arguments in favor of relativity of motion during the Parisian period and show the repercussion on his first conception of the corporeal substance. (shrink)

In this paper we study the impact of Leibniz’s critique of infinite numbers in his metaphysics of bodies. After presenting the relation that the German philosopher establishes in his youth between the notions of body, extension and infinite quantities, we analyze his thoughts on the paradoxes of the infinite numbers and we claim that his defense of the inconsistency of such numbers is an inflexion point in his conception of body and mark the beginning of his offensive against the res (...) extensa.

Resumen En el presente trabajo analizo el concepto de cuerpo en los escritos maduros de Leibniz. En el marco del debate contemporáneo acerca del estatus de la sustancia corpórea examino el entramado de las tres nociones sobre las que se construye la metafísica leibniziana de los cuerpos, a saber, la de materia prima, la de cuerpo orgánico y la de extensión. En cada caso evalúo el estatus ontológico que Leibniz les reconoce así como el papel que cumplen en su metafísica.In (...) this paper I examine the concept of body in Leibniz’s mature writings. In the context of the contemporary debate on the status of the corporeal substance, I analyze the relation between the three notions from which he builds his metaphysics of bodies, namely, the primary matter, the organic body, and the extension. For each case I evaluate their ontological status and the role they play in his metaphysics. (shrink)

En nuestro trabajo estudiamos el debate entre Leibniz y De Volder acerca de la naturaleza de la sustancia. En particular, argumentamos que a pesar de no encontrarse en la correspondencia un argumento a priori a favor de la definición de sustancia como fuerza primitiva activa, Leibniz presenta una justificación de la misma en otros términos. En primer lugar, analizamos la prueba a priori a favor de las fuerzas vivas y criticamos su validez para la metafísica. En segundo lugar, examinamos la (...) defensa que Leibniz lleva adelante de su definición y evaluamos el procedimiento que subyace a ella. (shrink)

En el presente trabajo analizamos la reforma que Leibniz propone entre 1677 y 1695 en la noción de cuerpo y, a partir de ello, esclarecemos el concepto de sustancia corpórea que presenta en esos años. En primer lugar, desarrollamos las críticas que esgrime contra la concepción geométrica del cuerpo propia de los filósofos modernos; en segundo lugar, examinamos los cambios que propone en dicha noción y su caracterización en clave de fuerza primitiva pasiva; en tercer lugar, estudiamos la definición hilemórfica (...) de la sustancia corpórea que ofrece y evaluamos el lugar que ella ocupa en su esquema metafísico.

Historians of philosophy are increasingly likely to emphasize the extent to which their work offers a pay‐off for philosophers of un‐historical or anti‐historical inclinations; but this defence is less familiar, and often seems less than self‐evident, to intellectual historians. This article examines this tendency, arguing that such arguments for the instrumental value of historical scholarship in philosophy are often more problematic than they at first appear. Using the relatively familiar case study of René Descartes' reading of his scholastic and Aristotelian (...) contemporaries, the article attempts to problematize this notion of pay‐off from an historian's perspective.

This article argues that early modern philosophy should be seen as an integrated enterprise of moral and natural philosophy. Consequently, early modern moral and natural philosophy should be taught as intellectual enterprises that developed hand in hand. Further, the article argues that the unity of these two fields can be best introduced through methodological ideas. It illustrates these theses through a case study on Scottish Newtonianism, starting with visions concerning the unity of philosophy and then turning to a discussion of (...) how methodological ideas figure in those visions. Finally, the article argues that methodological considerations can serve as good starting points to introduce and discuss central topics and canonical figures of the early modern period. (shrink)

I begin with a diagnosis. Present-day scholarly work on the Scottish Enlightenment is bifurcated: it is either focused on the areas of moral philosophy or of natural philosophy, broadly construed in both cases. The aspiration to combine these inquiries is rare and unsystematic. This paper makes a case for the need and possibility of a perspective that conceives moral and natural inquiry as integrated enterprises in the period. It also suggests that potentially useful interpretive devices can be adopted from the (...) historiography of science and philosophy, as well as science studies. (shrink)

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.

Este artigo busca mapear as diferenças e transformações que marcam a trajetória da noção leibniziana de substância ao longo dos quase trinta anos que separam suas primeiras e últimas sínteses de ar sistemático; percurso que vai do _Discurso de Metafísica_ à _Monadologia_ e aos _Princípios da Natureza e da Graça _. Poderemos, deste modo, fornecer um quadro de mecanismos conceituais e doutrinários que nos permita melhor compreender o estatuto coesivo de sua obra filosófica, donde encontraremos uma noção ampla mas singular (...) de substância que se define, sobretudo, pela articulação reversiva entre unidade e ação.

This paper consists in a study of Leibniz’s argument for the infinite plurality of substances, versions of which recur throughout his mature corpus. It goes roughly as follows: since every body is actually divided into further bodies, it is therefore not a unity but an infinite aggregate; the reality of an aggregate, however, reduces to the reality of the unities it presupposes; the reality of body, therefore, entails an actual infinity of constituent unities everywhere in it. I argue that this (...) depends on a generalized notion of aggregation, according to which a thing may be an aggregate of its constituents if every one of its actual parts presupposes such constituents, but is not composed from them. One of the premises of this argument is the reality of bodies. If this premise is denied, Leibniz’s argument for the infinitude of substances, and even of their plurality, cannot go through. (shrink)
