Our examination explicates not only how Leibniz’s emphasis on force or power squares well with (and most probably largely stems from) his endorsement of certain central Aristotelian tenets, but also how the concept of force is incorporated into his mature idealist metaphysics. That metaphysics, in turn, generates some thorny problems with regard to the concept of passivity; and so we shall also ask whether and how Leibniz’s monadology, emphasizing the activity as much as it does, is able to encompass the (...) passivity of created substances.

This paper explores the theory of freedom that Emilie du Châtelet advances in her essay “On Freedom.” Using contemporary terminology, we can characterize this theory as a version of agent-causal compatibilism. More specifically, the theory has the following elements: (a) freedom consists in the power to act in accordance with one’s choices, (b) freedom requires the ability to suspend desires and master passions, (c) freedom requires a power of self-motion in the agent, and (d) freedom is compatible with moral necessity (...) but not with physical necessity. While these elements may at first appear disparate, the paper shows that they fit together quite well. The resulting theory is a surprising combination of doctrines that appear to be based on Samuel Clarke’s libertarian account of free will and doctrines that are reminiscent of the compatibilist accounts of John Locke, Anthony Collins, Gottfried Leibniz, and Thomas Hobbes.

will give an overview of the fascinating communication between G. W. Leibniz and Pierre Bayle on pre-established harmony and sudden change in the soul which started from Bayle’s footnote H to the article “Rorarius” in his Dictionnaire historique et critique (1697) and ended in 1706 with Bayle’s death. I will compare the views presented in the communication to Leibniz’s reflections on the soul in his partly concurrent Nouveaux essais sur l’entendement humain (1704) and argue that many topics in the communication (...) with Bayle are discussed with more details in Nouveaux essais. I also argue that the communication helped Leibniz to respond to Locke’s views concerning uneasiness in An Essay Concerning Human Understanding, II, xxi. Bayle himself, however, was not able to completely understand Leibniz’s views on spontaneity as he was unaware of the contents of the Nouveaux essais, especially the systematic role of petites perceptions in Leibniz’s philosophy of mind. I will also reflect on whether the controversy could have ended in agreement if it would have continued longer. (shrink)

As far as treatments of causation are concerned, the pre-Kantian 18th century German context has long been dismissed as a period of uniform and unrepentant Leibnizian dogmatism. While there is no question that discussions of issues relating to causation in this period inevitably took Leibniz as their point of departure, it is certainly not the case that the resulting positions were in most cases dogmatically, or in some cases even recognizably, Leibnizian. Instead, German theorists explored a range of positions regarding (...) the nature of causal powers, the appropriate systems to explain the observed agreement between the states of substances, and the ground of free actions, or so I will argue in this chapter. Focusing on these three issues, I will here sketch the development of the debates relating to causation and trace the evolution of positions among the philosophers within the so-called Leibnizian-Wolffian philosophy as well as among its many opponents.

Moral rationalists and sentimentalists traditionally disagree on at least two counts, namely regarding the source of moral knowledge or moral judgements and regarding the source of moral motivation. I will argue that even though Leibniz's moral epistemology is very much in line with that of mainstream moral rationalists, his account of moral motivation is better characterized as sentimentalist. Just like Hume, Leibniz denies that there is a necessary connection between knowing that something is right and the motivation to act accordingly. (...) Instead, he believes that certain affections are necessary for moral motivation. On my interpretation, then, Leibniz is an externalist about judgements and motivation: he is committed to a gap between the judgement that something is morally right and the motivation to act accordingly. As a matter of fact, I will argue that there are two gaps. The first and less controversial one has to do with the fact that Leibniz reconciles his psychological egoism with ethical altruis..

Leibniz speaks, in a variety of contexts, of there being two realms—a "kingdom of power or efficient causes" and "a kingdom of wisdom or final causes." This essay explores an often overlooked application of Leibniz's famous "two realms doctrine." The first part turns to Leibniz's work in optics for the roots of his view that nature can be seen as being governed by two complete sets of equipotent laws, with one set corresponding to the efficient causal order of the world, (...) and the other to its teleological order. The second part offers an account of how this picture of lawful over-determination is to be reconciled with Leibniz's mature metaphysics. The third addresses a line of objection proposed by David Hirschmann to the effect that Leibniz's doctrine undermines his stated commitment to an efficient, broadly mechanical account of the natural world. Finally, the fourth part suggests that Leibniz's thinking about the harmony of final and efficient causes in connection with corporeal nature may help to shed light on his understanding of the teleological unfolding of monads as well.

Resumen El objetivo principal de este artículo es analizar la distinción leibniziana entre apercepción sensible y consáentia a la luz de su ontología monadológica, con la intención de esclarecer las diferencias constitutivas entre los tres tipos de mónadas que Leibniz postula, esto es, entre las mónadas simples, las meras almas y los espíritus. Con esto, además de argumentar en contra de la concepción estándar de la apercepción, la cual termina por confinarla al caso específico de los espíritus, sitúo la propuesta (...) del hannoveriano entre dos lecturas contemporáneas: por un lado, aquella que comprende la apercepción como un acto de orden superior reflexivo, esto es, una percepción de la percepción; y, por otro lado, aquella que, al distinguir entre apercepción sensible y consáentia, privilegia una teoría de primer orden para hablar de la primera, reservando los actos reflexivos para la segunda. Aunque la evidencia textual es más afín con la segunda, hay elementos de la primera que permiten matizarla.The main aim of this article is to analyze Leibniz’s distinction between sensitive apperception and ‘conscientia’ through his monadological ontology, with the intention of lighten the constitutive differences between the three types of monads that Leibniz state, that is, between bare monads, souls and spirits. By proving this, my approach not only argues against the standard conceptions of Leibniz's notion of apperception, which ends attributing apperception only to the specify case of spirits, but it abo places the Hanoverian proposal between two contemporary lectures: on one side, an approach that understand apperception as a high order reflexive act, that is, a perception of a perception; on the other side, an approach that distinguishes sensible apperception from ‘conscientia’ in order to privilege a first order theory for the first one, reserving the reflective acts only for the second. Even when the textual evidence is closer to the last one, there are some elements of the first approach that allow us to improve it. (shrink)

O objetivo principal deste artigo consiste em evidenciar a continuidade entre natureza e espírito no pensamento leibniziano. De fato, a adesão de Leibniz à ciência moderna é acompanhada de uma metafísica espiritualista, que o autor corrige no sentido de uma correspondência perfeita entre dois planos de fenómenos funcionando de acordo com princípios distintos. O elo de ligação entre esses dois planos é a noção de espontaneidade, que caracteriza a atividade da natureza e é elevada ao seu grau supremo através da (...) liberdade dos espíritos. (shrink)

Leibniz portrays the most fundamental entities in his mature ontology in at least three different ways. In some places, he describes them as mind-like, immaterial substances that perceive and strive. Elsewhere, he presents them as hylomorphic compounds. In yet other passages, he characterizes them in terms of primitive and derivative forces. Interpreters often assume that the first description is the most accurate. In contrast, I will argue that the third characterization is more accurate than the other two. If that is (...) correct, Leibniz’s monadological metaphysics is even more radical than it initially seems: his ontology is best understood not as a substance-mode ontology but as a force ontology. At the metaphysical ground floor, we do not find substances that possess force; instead, we just find forces. Interpreting Leibniz as a force ontologist has far-reaching consequences. For instance, it requires us to reconsider the status of time in Leibniz’s system and to revise our understanding of appetitions and perceptions. (shrink)
