Perception plays a central and wide-ranging role in the philosophy of Margaret Cavendish. In this paper, I argue that Cavendish holds a naïve realist theory of perception. The case draws on what Cavendish has to say about perceptual presentation, the role of sympathy in experience, the natures of hallucination and of illusion, and the individuation of kinds. While Cavendish takes perception to have representational content, I explain how this is consistent with naïve realism. In closing, I address challenges to the (...) interpretation, one of which turns on whether Cavendish allows for action at a distance. I argue that she does. (shrink)

Descartes notoriously characterizes substance in two ways: first, as an ultimate subject of properties ; second, as an independent entity. The characterizations have appeared to many to diverge on the definition as well as the scope of the notion of substance. For it is often thought that the ultimate subject of properties need not—and, in some cases, cannot—be independent. Drawing on a suite of historical, textual, and philosophical considerations, this essay argues for an interpretation that reconciles Descartes's two characterizations. It (...) proposes that both characterizations invoke a type of independence that obtains just in case there is no relation to another entity that holds by the nature of the entity in question. Even though the ultimate subject of properties is sometimes not independent in other respects, it satisfies this independence-by-nature condition. (shrink)

The article defines the problem of the nature of ideas in Descartes’s philosophy according to the ontology of substances. First, it illuminates Descartes’s relation to antecedent theories of ideas (as platonic forms or as corporal images) and demonstrates that, in opposition to them, Descartes conceives ideas as modes of thinking substance. Then, it develops two possible explanations of his theory. The first one understands an idea as a complex consisting of perception and its necessary internal object, which enables the representation (...) of external objects. The second one understands it as an act with intrinsic representative structure. By using Arnauld’s analysis of Descartes’s texts, it demonstrates that in accordance with the second model, an idea is a singular mode of thinking substance, which should at the same time be understood as an act of mind and as a representation of objects.

At the heart of Descartes’s theory of cognition is the act of perceiving an idea. However, it remains unclear what precisely an idea is, what the act of perceiving ideas amounts to, and how that act contributes to the formation of cognition under Descartes’s view. In this paper, I provide an account of perceiving ideas that clarifies Descartes’s notion of an idea and explains the fundamental role that the perceiving of ideas occupies in his theory of cognition. At the end (...) of the paper, I will address an issue that arises regarding the objective reality of ideas and the unity of mind. (shrink)

My aim is to arrive at a better understanding of the distinction between direct realism and representationalism by offering a critical analysis of Steven Nadler.

The question of how and why the application of mathematics to physical reality is possible has occupied philosophers for many centuries. In contemporary discussions, Philip Kitcher’s attack on a priorist approaches to the question is particularly interesting, for it suggests that there is no global answer (Kitcher 1983, Chapters 1-4). In this essay, I would like to develop his insight by arguing, first, that the problem of how mathematics relates to physical reality should be addressed by an appeal to the (...) history of mathematics and the sciences in the form of case studies which analyze the peculiar and changing ways in which these domains interact. Generalizations about such interaction should be made carefully, in a kind of local and piecemeal retrospective; I believe that the historical record will show that the grounds of justification and the form of applied mathematics changes dramatically from one historical era to the next.

Many critics, Descartes himself included, have seen Hobbes as uncharitable or even incoherent in his Objections to the Meditations on First Philosophy. I argue that when understood within the wider context of his views of the late 1630s and early 1640s, Hobbes's Objections are coherent and reflect his goal of providing an epistemology consistent with a mechanical philosophy. I demonstrate the importance of this epistemology for understanding his Fourth Objection concerning the nature of the wax and contend that Hobbes's brief (...) claims in that Objection are best understood as a summary of the mechanism for scientific knowledge found in his broader work. Far from displaying his confusion, Hobbes's Fourth Objection in fact pinpoints a key weakness of Descartes's faculty psychology: its unintelligibility within a mechanical philosophy. (shrink)
