The expression ‘rationalism’ is a historiographical category that refers to a set of views more or less shared by a number of philosophers active in the seventeenth and eighteenth centuries. This period saw the heyday of metaphysical system-building, but the expression ‘rationalism’, as the term is understood in this entry, connotes primarily epistemological commitments. Since the early twentieth century, ‘rationalism’ has typically been presented in contrast with ‘empiricism’. By contrast to so-called ‘empiricism’, which traces (all) knowledge to sensory experience, ‘rationalists’ tend to rely upon the powers of reason to explain and justify what we know. This entry provides an account of the traditional narrative of early modern ‘rationalism’ while also extending that narrative to cover figures from typically under-represented backgrounds who hold commitments that can also plausibly be characterized as ‘rationalist’. The entry thus covers René Descartes (1596–1650), Baruch Spinoza (1632–1677), and Gottfried Wilhelm Leibniz (1646–1716), alongside Anton Wilhelm Amo (1703–1759), Margaret Cavendish (1623–1673), and Anne Conway (1631–1679). The entry also concludes by briefly suggesting future directions for scholarship on early modern rationalism involving the application of rationalist principles in topics such as social and political philosophy, as illustrated through the writings of Sor Juana Inés de la Cruz (1645–1695) and François Poulain de la Barre (1647–1723).

Is it possible to explain the existence of evil under the supposition of a supremely good creator? Are we ourselves the cause of most of the suffering that befalls us? Is life generally more painful than it is pleasant, and if so is non-existence preferable to existence? Is happiness ever even attainable? These questions occupied some of the best-known philosophers of the 17th to 19th centuries—figures such as G. W. Leibniz, Pierre Bayle, David Hume, Jean-Jacques Rousseau, Voltaire, Immanuel Kant, Arthur Schopenhauer, and Friedrich Nietzsche. These questions were also richly discussed by writers often since excluded from the philosophical canon, such as Ottobah Cugoano, Mary Astell, and Olga Plumacher. For these thinkers, philosophy was not only a fair-weather friend; it was also a companion in storms and in darkness—it was a way of thinking about, thinking through, and contending with the profoundly unsettling. In this unique and provocative anthology, one will find philosophers bending their intellectual efforts to the darker side of life.

Over the span of eleven years, Nicolas Malebranche and Antoine Arnauld, two prominent sympathizers of the Cartesian tradition, engaged in a rigorous debate. In his initial set of criticisms, Arnauld objects that a natural consequence of Malebranche’s theory of ideas is idealism.1 This charge of idealism has puzzled scholars: why did Arnauld believe this? Han Adriaenssen2 has convincingly argued that Arnauld’s charge of idealism is founded on the representationality of Malebranchean ideas. According to Arnauld, ideas represent for Malebranche in much the same way that portraits do—by inciting a perceiver to form a conception of whatever they pertain to. The portrait of Louis XIV, for example, represents the French monarch by inciting a conception that pertains to him in a perceiver. However, a portrait will only represent Louis XIV to a perceiver that is already familiar with the king. Only then will the conception of Louis XIV arise in a perceiver that actually pertains to him. Similarly, then, an idea of the sun will only represent it to a perceiver with a previous conception of the sun. But, for Malebranche, the conception of an object requires the perception of the idea which represents that object. Thus, a perceiver cannot have a conception of the sun prior to the perception of its idea. Malebranchean ideas accordingly fail to function as representations of their objects. In failing to represent external objects, moreover, the ideas in the divine intellect are not just the immediate objects of our perception, but the only objects of our perception. Consequently, Arnauld concludes that Malebranche’s view leads to idealism. Arnauld’s objection, however, presupposes a particular account of representation, namely, resemblance. For a prior conception of what an idea represents would be required in order for the idea to actually represent its object only if ideas represented by resembling their objects as portraits do. This paper will challenge the traditional3 characterization of the representationality of Malebranchean ideas in terms of resemblance. I argue that a careful examination of Malebranche’s texts, and of the Neoplatonic-Augustinian sources upon which Malebranche bases his theory of ideas, reveals that Malebranche is not steadfastly committed to the view that ideas represent by means of resemblance, but instead, by archetypal participation. On this view, Malebranchean ideas are divine archetypes wherein the essences of objects participate by being the exemplary causes of these essences. And it is in virtue of this causal relation that ideas represent the essences of objects. So, as regards external bodies, the idea of intelligible extension is the archetype of bodies which represents their essence, viz., extension, in virtue of being the exemplary cause of extension in bodies. When we interpret Malebranche’s view of ideational representation this way, the charge of idealism broached by Arnauld, and some recent commentators4, dissipates. This is because Malebranchean ideas, in conjunction with particular sensations, can direct a perceiver to the cognition of individual bodies that participate in the idea of intelligible extension without a prior conception of these bodies.

Abstract:Transubstantiation is a philosophical term used to describe what takes place in the rite of the Eucharist. The rite was proposed as a test case by Arnauld in his objections to Descartes's Meditations. The most credible, well-founded response came from Robert Desgabets, who in his account of transubstantiation appealed in one fashion or other to five principles variously found among other Cartesians as well as Descartes himself—principles of intentionality, clear and distinct perception, the status of sensible qualities, exemplification, and cognitive transcendence.
