I defend the correspondence theory of truth, according to which a statement’s truth consists in a relation of correspondence with extralinguistic fact. There are well-known objections to this view, which I consider and rebut, and also important rival accounts, principal among which are so-called deflationist theories and epistemic theories. Epistemic theories relate the concept of truth to our state of knowledge, but fail, I argue, to respect the crucial distinction between a criterion of truth and the meaning of truth: the (...) view that one cannot do semantics, or metaphysics, without addressing epistemic issues is rejected by this work. Against epistemic theories, I illustrate how truth is independent of epistemic considerations. Deflationism is the more popular of the rival accounts and has gained considerable momentum over the past two decades. It is therefore dealt with in greater detail by this work. Deflationist theories exploit the paradigmatic ‘“Snow is white” is true iff snow is white’ biconditional to argue for an insubstantialist account, according to which truth is conservative with respect to non-semantical facts. On this view, truth’s raison d’être is merely to perform the useful expressive function of generalising over possibly infinite sets of assertions. Against deflationist theories, I claim that the work done by Jeffrey Ketland and Stewart Shapiro conclusively demonstrates how truth is informationally additive over non-semantic facts, while deflationism itself is also an excessively impoverishing theory, inadequate to the tasks it purports to accomplish. This work also defends the thesis that Alfred Tarski’s well-known theory of truth is an authentic correspondence theory. To say this is to say that the clauses of a Tarskian truth-definition can be interpreted in terms of a relation of correspondence that holds between true sentences and the states of affairs they describe. I provide a precise account of what the correspondence in question consists in, claiming that true sentences are homomorphic images of facts, i.e. a true sentence represents, in a form-preserving manner, the truth-making facts in it. This gives precise expression to Wittgenstein’s thesis that true sentences picture the world. (shrink)

This article performs a word history on correspondentia, a neo-Latin construction by Thomas Aquinas in Scholastic thought attempting to interpret Aristotle on the perception of truth, and then tracks succeeding circles of the neologism’s utility. The new term “correspondentia” performs a crucial role in shaping correspondence theory in early modern hermetic thought and again in modern neo-Cartesian thought. A thread of shared discourse demonstrates an ­interconnected journey for the neologism from Aquinas through these contiguous ­conversations all the way to Swedenborg’s (...) sophisticated esoteric “science of correspondences.” Typical of figures in Western esoteric and New Religious Movements, Swedenborg makes claims of ahistorical and direct apprehension of theosophical information regarding unseen realms, providing a useful case study for contextual analysis of how cultural transmission and interdiscursivity shape transcendental traditions. Swedenborg claims an ahistorical reception of his “science of correspondences” in his eight-volume masterwork Arcana Coelestia, where he lays out his first and most exhaustively demonstrated declarations of correspondences as the key to sacred scripture and to a vast bank of information on unseen realms. Analysis of primary sources and his environment of thought, however, betrays the Swedish polymath as deeply embedded in kabbalist, hermetic, and neo-Cartesian discourse for his impressive development of correspondence theory.

Gettier’s paper, “Is Justified True Belief Knowledge?,” is widely taken to be a paradigm example of the sort of philosophical methodology that has been so hotly debated in the recent literature. Reflection on it motivates the following four theses about that methodology: (A) Intuitive judgments form an epistemically distinctive kind. (B) Intuitive judgments play an epistemically privileged role in philosophical methodology. (C) If intuitive judgments play an epistemically privileged role in philosophical methodology, then their role is to be taken as (...) given inputs into generally accepted forms of reasoning. (D) Philosophical methodology is reasonable. Negative experimental philosophers have empirically challenged (D). Radical responses to their challenge include Williamson’s rejection of (A) and Cappelen and Deutsch’s rejection of (B). Here I follow traditionalists in maintaining (A), (B), and (D), but suggest questioning (C), which has largely been taken as a fixed point in the literature. (shrink)

This essay examines the relationship between monads and space in Kant’s early pre-critical work, with special attention devoted to the question of ubeity, a Scholastic doctrine that Leibniz describes as “ways of being somewhere”. By focusing attention on this concept, evidence will be put forward that supports the claim, held by various scholars, that the monad-space relationship in Kant is closer to Leibniz’ original conception than the hypotheses typically offered by the later Leibniz-Wolff school. In addition, Kant’s monadology, in conjunction (...) with God’s role, also helps to shed light on further aspects of his system that are broadly Leibnizian, such as monadic activity and the unity of space.

In 1675, Burchard de Volder became the first university physics professor to introduce the demonstration of experiments into his lectures and to create a special university classroom, The Leiden Physics Theatre, for this specific purpose. This is surprising for two reasons: first, early pre-Newtonian experiment is commonly associated with Italy and England, and second, de Volder is committed to Cartesian philosophy, including the view that knowledge gathered through the senses is subject to doubt, while that deducted from first principles is (...) certain. On the surface, it is curious that such a man would bring experiments to university physics. After all, in demonstrating experiments to his students, he was teaching them through their senses, not reason. However, if we consider the institutional context of de Volder’s teaching, we come to see de Volder’s Cartesian experimentalism as representative of a certain form of pre-Newtonian Dutch Cartesian science, as well as part of a larger tradition of teaching through observation at the University of Leiden. Considering de Volder’s institutional context will help us see that de Volder’s experimentalism was not in spite of his Cartesianism, but motivated by it. This paper will describe de Volder’s physics curriculum, the Theatre in which it was taught and how his work predates similar efforts in other European Universities. The second part will consider three aspects of the culture at the University of Leiden: a tradition of teaching through observation, a particular reception of Cartesianism, and an eclectic approach to the New Philosophy. The concluding portion shows how de Volder would have understood his enterprise in Cartesian terms. (shrink)

Philosophers today have largely given up on the project of categorizing being. Aristotle’s ten categories now strike us as quaint, and no attempt to improve on that effort meets with much interest. Still, no one supposes that reality is smoothly distributed over space. The world at large comes in chunks, and there remains a widespread intuition, even among philosophers, that some of these chunks have a special sort of unity and persistence. These, we tend to suppose, are most truly agents (...) and subjects, and are what exist in the most proper sense of the term. We believe, in other words, in substances. (shrink)

Descartes maintains that we can love God and that it is pleasant and morally beneficial to do so. In this essay, I examine the necessary conditions for such an intellectual love of God. I argue that the intellectual love of God is incited by a judgment that we are joined to God in reality, which is constitutive of an intellectual joy. I go on to show that the intellectual love of God is, itself, constituted by a stripping of our private (...) interests in favor of God’s divine will. (shrink)

This paper attempts to resolve the apparent conflict between Descartes’ commitments to the creation doctrine and the necessity of eternal truths by elaborating different conceptions of necessity in Descartes’ framework. More specifically, I argue that the fact that Descartes concedes the necessity of eternal truths does not compel him to assert the impossibility of their negation. Necessity, for Descartes, rather means immutability. Descartes distinguishes two kinds of immutable truths. While truths about God’s essence are absolutely immutable, truths about the essences (...) of God’s creation are conditionally immutable, i.e., they can change if God’s will changes. Since there are different kinds of eternal truths, they express different kinds of necessity as well, namely conditional and absolute necessity. After I clarify these two kinds of necessity, I explain how Descartes coherently maintains both that eternal truths are necessary and that God could have created eternal truths otherwise without undermining their necessity.

The study is focused on the relation between theology and mathematics in the situation of increasing secularization. My main concern in the second part of this paper is the early-twentieth-century foundational crisis of mathematics. The hypothesis that pure mathematics partially fulfilled the functions of theology at that time is tested on the views of the leading figures of the three main foundationalist programs: Russell, Hilbert and Brouwer.

Intuitively it has seemed to many that our concepts conscious state and conscious creature are sharp rather than vague, that they can have no borderline cases. On the other hand, many who take conscious states to be identical to, or realized by, complex physical states are committed to the vagueness of those concepts. In the paper I argue that conscious state and conscious creature are sharp by presenting four necessary conditions for conceiving borderline cases in general, and showing that some (...) of those conditions cannot be met with conscious state. I conclude that conscious state is sharp, and the conclusion is then extended to conscious creature. The paper ends with a brief discussion of some implications. (shrink)

A case study in historical cognitive science, this paper addresses two claims made by radical proponents of new dynamical approaches. It queries their historical narrative, which sees embodied, situated cognition as correcting an individualist, atemporal framework originating in Descartes. In fact, new Descartes scholarship shows that 17th-century animal spirits neurophysiology realized a recognizably distributed model of memory; explicit representations are patterns of spirit flow, and memory traces are changes left by experience in connections between brain pores. This historical sketch supports (...) the second dynamicist claim, that connectionists' stress on the cognitive importance of pattern-recreation needs supplementing by dynamicists' real-time focus and attention to the active roles of body and environment. Animal spirits theory exhibits just the 'continuous reciprocal causation' between brain, body, and environment which Andy Clark sees as dynamicism's central contribution, and allows for the embedding of brains in culture as well as the physical world.

What does Descartes regard as necessary for human freedom? I approach this topic from a distinctive angle by focusing on the role of the passions in Descartes’s account of free will. My goal is to show that (1) Descartes takes us to have the ability to do otherwise when we judge or choose under the influence of the passions, and that (2) while such ability does not constitute freedom in the fullest Cartesian sense, it does ensure that the judgments and (...) choices we make in response to passions are neither compelled nor unfree, but under our control.

This essay demonstrates the inadequacy of contemporary substantivalist and relationist interpretations of quantum gravity hypotheses via an historical investigation of the debate on the underlying ontology of space in the seventeenth century. Viewed in the proper context, there are crucial similarities between seventeenth century theories of space and contemporary work on the ontological foundations of spacetime theories, and these similarities challenge the utility of the substantival/relational dichotomy by revealing a host of underlying conceptual issues that do not naturally align with (...) that distinction.

El término “conocimiento” y la disciplina filosófica que lo estudia —la teoría del conocimiento— han experimentado notables cambios hasta el presente. La teoría clásica concibe el conocimiento en íntima unión con la verdad, como una captación intelectual de realidades necesarias e inmutables. Con la llegada de la modernidad, la difusión de un clima escéptico puso en duda esta pretensión, cuestionando la aptitud misma del conocimiento para la verdad. Esta duda ha presidido toda la modernidad hasta el presente. Para responder al (...) desafío escéptico, las principales corrientes de la llamada epistemología analítica contemporánea han intentado, sin éxito, explorar el carácter justificante del conocimiento. En este intento, han destacado teorías encaminadas a mostrar que el conocimiento recibe su justificación desde un fundamento, como el fundacionismo y el coherentismo; teorías encaminadas a mostrar que el conocimiento recibe su justificación desde sus fuentes, como el externismo y el internismo; y teorías encaminadas a mostrar que la recibe por las facultades cognitivas mismas como instrumentos de conocimiento fiables, como la epistemología de la virtud. Todas ellas generan, a su vez, nuevas paradojas e imponen la necesidad de volver a los fundamentos de esta disciplina, presentes en la teoría clásica, para descubrir la conexión entre conocimiento y verdad, e intentar detener el desafío escéptico.

A striking feature of Newton’s thought is the very broad reach of his empiricism, potentially extending even to immaterial substances, including God, minds, and should one exist, a non-perceiving immaterial medium. Yet Newton is also drawn to certain metaphysical principles—most notably the principle that matter cannot act where it is not—and this second, rationalist feature of his thought is most pronounced in his struggle to discover ‘gravity’s cause’. The causal problem remains vexing, for he neither invokes primary causation, nor accepts (...) action at a distance by locating active powers in matter. To the extent that he is drawn to metaphysical principles, then, the causal problem is that of discovering some non-perceiving immaterial medium. Yet Newton’s thought has a third striking feature, one with roots in the other two: he allows that substances of different kinds might simultaneously occupy the very same region of space. I elicit the implications of these three features. For Newton to insist upon all three would transform the causal question about gravity into an insoluble problem about apportioning active powers. More seriously, it would undermine his means of individuating substances, provoking what I call ‘Newton’s Substance Counting Problem’. (shrink)

In this paper I reply to the four critical articles that were provided in response to my book Deconstruction (MIT Press 2021). It proceeds in four steps: (1) I begin with a reply to Stanisław Chankowski’s use of the psychoanalytic term “fetishistic denial” to describe the formal character of the text. (2) I then engage with the criticism supplied by Piotr Kozak, who questions deconstruction’s theory of truth (or its lack thereof). (3) From this, I take-up and respond to Przemysław (...) Nowakowski’s proposal that deconstruction might provide a way to reimagine the interdisciplinarity of cognitive science. And (4) I conclude with a response to Michał Piekarski’s mashup of Ludwig Wittgenstein and Jacques Derrida, which supplies a reading of these two thinkers that is arguably greater than the sum of the parts. The objective of the reply is not to offer a defense of myself or my text but to engage with these interesting and insightful reviews in a way that opens the space for productive dialogue. -------------------------- Received: 28/09/2023.

Central to Descartes’ philosophy is a view about immutable essences and eternal truths. After mentioning a Platonist account of recollection in Meditation V, Descartes declares that the ideas we have of mathematical notions “are not my invention but have their own true and immutable natures” (AT VII, 64/CSM II, 44).Descartes claims that other important philosophical notions, such as God, mind, body, and human free will (AT VII, 68; AT VIII-2, 348; AT III, 383; AT VII, 433, respectively), also have immutable (...) natures or essences. Although Descartes says a good many things about this view, nowhere does he offer definitive doctrine on the matter, and in fact frequently confuses his reader with apparently inconsistent pronouncements about immutable natures and eternal truths. In this essay, I focus on the immutable natures and propose a solution to two of the main problems associated with Descartes’ position, the metaphysical status of immutable natures and the purported indivisibility of their existence as ideas in the mind.
