In this paper I criticize arguments by Pauline Phemister and Matthew Stuart that John Locke's position in his An Essay Concerning Human Understanding allows for natural kinds based on similarities among real essences. On my reading of Locke, not only are similarities among real essences irrelevant to species, but natural kind theories based on them are unintelligible.

This article canvases the main areas of controversy: the nature of Lockean signification and his position on propositions and particles.

In 1765, Joseph Priestley created what may be the world's first modern timeline, A Chart of Biography. This paper offers the first study of the philosophy underlying Priestley's timeline. It argues that Priestley was pushed towards representing times as lines by his views on abstract ideas and time, and there is no reason to believe that Newtonian absolutism grounds his uniform depiction of time. Further, the Chart confirms, and even advances, Priestley's views on human progress. Finally, this study shows that (...) Priestley's conception of time as a line comprises a landmark contribution to the history of space-time parallelism. (shrink)

Much recent philosophy of perception is preoccupied with finding a place for phenomenal character in a physical world. By contrast, Locke’s philosophy of sensory perception is an episode in his ‘Historical, plain method’ and seeks to map out the processes by which we experience ordinary objects. On Locke’s account, our ideas of primary and secondary qualities enter the mind ‘simple and unmixed’; having an idea of a colour, for example, is not necessary for the visual experience of a shape. An (...) analysis of the Molyneux problem reveals that, for Locke, judgment corrects the initial two-dimensional idea vision presents us with. Nevertheless, Locke’s position is problematic: he has no account of how we pair ideas of primary and secondary qualities, nor of how we could experience a colourless visual idea of shape. (shrink)

The goal of this paper is show how an initially appealing objection to David Hume's account of judgment can only be put forward by philosophers who accept an account of judgment that has its own sizable share of problems. To demonstrate this, I situate the views of John Locke, David Hume, and Thomas Reid with respect to each other, so as to illustrate how the appealing objection is linked to unappealing features of Locke's account of judgment.

Thomas Reid's philosophy of mind, epistemology, and philosophy of language all rely on his account of signs and signification. On Reid's view, some entities play a role of indicating other entities to our minds. In some cases, our sensitivity to this indication is learned through experience, whereas in others, the sensitivity is built in to our natural constitutions. Unlike representation, which was presumed to depend on resemblances and necessary connections, signification is the sort of relationship that can occur without any (...) intrinsic ties between the sign and the thing signified. Of particular interest is the priority Reid gives to natural signs. Reid deploys his robust account of natural signs in a way that allows him to sidestep some skeptical worries common in the early modern period, as well as in grounding “artificial” human languages like English or Cantonese on a more basic human capacity for communication, that is, itself, the result of our sensitivity to natural signs of other people's minds.

To understand pre-Fregean theories of judgment and proposition, such as those found in Locke and the Port-Royal logic, it is important to distinguish between propositions in the modern sense and propositions in the pre-Fregean sense. By making this distinction it becomes clear that these pre-Fregean theories cannot be meant to solve the propositional attitude problem. Notwithstanding this fact, Locke and Arnauld are able to make a distinction between asserted and unasserted propositions (in their sense). The way Locke makes this distinction (...) turns out to be very different from the way it is made by Arnauld. (shrink)

This article is an extended analysis of the most recent scholarly work on Locke's account of sensitive knowledge. Lex Newman's "dual cognitive relations" model of sensitive knowledge is examined in detail. The author argues that the dual cognitive relations model needs to be revised on both philosophical and historical grounds. While no attempt is made to defend Locke's position, the aim is to show that it is at least consistent, contrary to the received view. The final section provides textual support (...) for the interpretation. (shrink)

Molyneux’s question asks whether someone born blind, who could distinguish cubes from spheres using his tactile sensation, could recognize those objects if he received his sight. Locke says no: the newly sighted person would fail to point to the cube and call it a cube. Locke never provided a complete explanation for his negative response, and there are concerns of inconsistency with other important aspects of his theory of ideas. These charges of inconsistency rest upon an unrecognized and unfounded assumption (...) that seeing entails recognition. Locke’s negative answer to Molyneux’s question is consistent with his other philosophical commitments. (shrink)

Locke defines knowledge as the perception of the agreement or disagreement of ideas. Nevertheless, he claims that we know particular things: the identity of our ideas, our own existence, and the existence of external objects. Although much has been done to reconcile the definition of knowledge with our knowledge of external objects, there is virtually nothing in the scholarship when it comes to knowing ideas or our own existence. I fill in this gap by arguing that perceptions of ideas are (...) complex mental states that convey propositional knowledge due to agreeing elements therein. (shrink)

One recent trend in Kant scholarship has been to read Kant as undertaking a project in philosophical semantics, as opposed to, say, epistemology, or transcendental metaphysics. This trend has evolved almost concurrently with a debate in contemporary philosophy of mind about the nature of concepts and their content. Inferentialism is the view that the content of our concepts is essentially inferentially articulated, that is, that the content of a concept consists entirely, or in essential part, in the role that that (...) concept plays in a system of inferences. By contrast, relationalism is the view that this content is fixed by a mental or linguistic item's standing in a certain relation to its object. The historical picture of Kant and the contemporary debate about concepts intersect in so far as contemporary inferentialists about conceptual content often cite Immanuel Kant not only as one of the founding fathers of a tradition that leads more or less straightforwardly to contemporary inferentialism, but also as the philosopher who first saw the fatal flaws in any attempt to articulate the content of our concepts relationally.

Against the dominant view in contemporary Hobbes scholarship, I argue that Hobbes’ philosophy of language implicitly denies that linguistic expressions refer to anything. I defend this thesis both textually, in light of what Hobbes actually said, and contextually, in light of Hobbes’ desertion of the vocabulary of suppositio, which was prevalent in semantics leading up to Hobbes. Hobbes explained away the apparent fact of linguistic reference via a reductive analysis: the relation between words and things wholly reduces to a composite (...) of the relation of signification between words and conceptions on the one hand, and the relation of representation between conceptions and things on the other. Intentionality, for Hobbes, accrues to conceptions, not words. (shrink)

Almost all scholars of the Enlightenment consider Hobbes, Spinoza, and Locke as the founding theorists of the “secular modern state.” In contrast to the widely held view of the modern state, I argue that far from being “secular” it was the product of the sacralization of politics, which resulted from the way these philosophers interpreted the Scriptures as part of their philosophical inquiries. The analysis of the “linguistic turn” in their biblical interpretations reveals how they tried to undermine the power (...) of the Church to claim greater freedoms for the state. Their philosophical inquiries initiated the secularization of the Christian religion and the sacralization of politics as two correlative developments, rather than the secularization of the state per se, as is usually supposed. The philosophical arguments proposed by Hobbes, Spinoza, and Locke helped to resolve the religious battles of Europe’s many confessions in the seventeenth and eighteenth centuries, but are still pertinent to our c...
