Descartes is not widely recognized for his ethics; indeed, most readers are unaware that he had an ethics. However, Descartes placed great importance on his ethics, claiming that ethics is the highest branch of his philosophical system. I aim to understand the systematic relationship Descartes envisions between his ethics and the rest of his philosophy, particularly his metaphysics and epistemology. I defend three main theses. First, I argue against the recent trend in the literature that claims that the chief virtue (...) in Descartes’ ethics—generosity—is acquired in the Meditations. On this view, the presence of moral virtue in the Meditations shows that ethical practice is intertwined with metaphysics and epistemology. I argue that generosity cannot be acquired in the Meditations because acquiring generosity presupposes several metaphysical and physical truths that the meditator cannot access given her epistemic position. Thus, I maintain that metaphysics and epistemology is foundational to ethics. Second, I resolve the tension between Descartes’ description of distinct virtues, and his insistence that there is only a single virtue—the disposition to judge well. Drawing from his theory of conceptual distinction in his metaphysics, I argue that Descartes offers a unique account of the unity of the virtues. Although Descartes describes different virtues, he thinks that all of them are identical to each other because they are reducible to the disposition to judge well. Nonetheless, we can conceptually distinguish between the virtues because we can regard the disposition to judge well in different ways given the various applications it has in different types of moral situations. Third, I show that some of Descartes’ ethical concepts inform his epistemology. I draw from Descartes’ theory of virtue to address “the problem of knowledge preservation,” that is, how to render perfect knowledge— scientia—stable in light of the instability of clear and distinct perceptions. I argue that Descartes intends to preserve scientia by grounding items of scientia in virtuous habits of belief. These habits of belief are established through repeated engagement with cognitive routes to clear and distinct perceptions, and are ultimately grounded in memory. This reading has the advantage of explaining Descartes’ notoriously confusing remarks about memory in response to the Cartesian circle. (shrink)

In the Fifth Meditation Descartes considers the problem of knowledge preservation : the challenge of accounting for the diachronic certainty of perfect knowledge [scientia]. There are two general solutions to PKP in the literature: the regeneration solution and the infallible memory solution. While both readings pick up on features of Descartes’ considered view, I argue that they ultimately fall short. Salvaging pieces from both readings and drawing from Descartes’ virtue theory, I argue on textual and systematic grounds for a dispositionalist (...) solution. On this view, the diachronic certainty of scientia is achieved through virtuous habits of belief. (shrink)

The standard interpretation of Descartes's ethics maintains that virtue presupposes knowledge of metaphysics and the sciences. Lisa Shapiro, however, has argued that the meditator acquires the virtue of generosity in the Fourth Meditation, and that generosity contributes to her metaphysical achievements. Descartes's ethics and metaphsyics, then, must be intertwined. This view has been gaining traction in the recent literature. Omri Boehm, for example, has argued that generosity is foundational to the cogito. In this paper, I offer a close reading of (...) Cartesian generosity, arguing that the meditator cannot acquire generosity in the Second or Fourth Meditation. (shrink)

I argue that Descartes intended the so-called ontological "argument" as a self-validating intuition, rather than as a formal proof. The textual evidence for this view is highly compelling, but the strongest support comes from understanding Descartes's diagnosis for why God's existence is not 'immediately' self-evident to everyone and the method of analysis that he develops for making it self-evident. The larger aim of the paper is to use the ontological argument as a case study of Descartes's nonformalist theory of deduction (...) and his method of analysis, showing how he conceives the latter as a form of philosophical therapy.

In this paper, I argue that it is in the fourteenth century that the problem of the compatibility or unity of efficient and final causality emerges. William Ockham and John Buridan start to flirt with a mechanized view of nature solely explainable by efficient causality, and they hence push final causality into the human mind and use it to explain for example action, morality and the good. Their argumentation introduces the problem of how to give a unified account of the (...) world, that is, how are nature and freedom compatible. In the paper, I set up the discussion by going through some of the problems associated with final causality in the seventeenth century and show that Ockham and Buridan's problems are similar. I then argue using a formulation from Leibniz's Monadology that the problems here traced should be seen as versions of the mind/body problem. (shrink)
