From Leibniz to Krauss philosophers and scientists have raised the question as to why there is something rather than nothing. Why-questions request a type of explanation and this is often thought to include a deductive component. With classical logic in the background only trivial answers are forthcoming. With free logics in the background, be they of the negative, positive or neutral variety, only question-begging answers are to be expected. The same conclusion is reached for the modal version of the Question, (...) namely ‘Why is there something contingent rather than nothing contingent?’. The categorial version of the Question, namely ‘Why is there something concrete rather than nothing concrete?’, is also discussed. The conclusion is reached that deductive explanations are question-begging, whether one works with classical logic or positive or negative free logic. I also look skeptically at the prospects of giving causal-counterfactual or probabilistic answers to the Question, although the discussion of the options is less comprehensive and the conclusions are more tentative. The meta-question, viz. ‘Should we not stop asking the Question’, is accordingly tentatively answered affirmatively. (shrink)

As a unique method of philosophical argument, performative contradiction attracted general attention after the change in direction of pragmatics in the twentieth century. Hintikka used this method to conduct an in-depth analysis of Descartes’ proposition “I think, therefore I am,” providing a proof which is a model in the philosophical history; Apel absorbed performative contradiction into his own framework of a priori pragmatics; and Habermas introduced it into the theory of formal pragmatics and rendered it an effective weapon of debate. (...) Wittgenstein, who had fallen into the trap of performative contradiction in Tractatus Logico-Philosophicus, later managed to extract himself from it and indeed used the methodology of performative contradiction to cure the ills of philosophy, making it a general philosophical method. Through analysis of its connotations and classic examples of its use we can see that it is crucial in refuting extreme relativism and skepticism, and hence provides methodological support for a new foundation for philosophical paradigms.

The so-called knowability paradox results from Fitch's argument that if there are any unknown truths, then there are unknowable truths. This threatens recent versions of semantical antirealism, the central thesis of which is that truth is epistemic. When this is taken to mean that all truths are knowable, antirealism is thus committed to the conclusion that no truths are unknown. The correct antirealistic response to the paradox should be to deny that the fundamental thesis of the epistemic nature of truth (...) entails the knowability of all truths. Correctly understood, the antirealistic conditions on a proposition's truth do not require that the proposition possess a verification-procedure which, when executed under the given conditions, issues in an agent's recognition of truth, but merely that there be a verification-procedure which, under these conditions, takes the value true . The knowability paradox and the related idealism problem (that antirealism seems, but is not, committed to the necessary existence of an epistemic agent) draw attention to the fact that certain propositions, those that are about verification-procedures themselves, may under certain conditions take the value true despite their unperformability under these circumstances. Thus these propositions' procedures can only be performed when the propositions are false, and they gain the appearance of antirealistic impossibility (e.g., that there is an unknown truth). This differs from the unperformability that antirealists object to, pertaining merely to matters of execution rather than to the logical structure of the procedures themselves. The force of antirealism's notion of epistemic truth is piecemeal, rather than consisting in a blanket characterization of truth as knowable. (shrink)

This paper follows the tradition of treating Zhuangzi's Butterfly Dream episode as presenting a version of skepticism. However, unlike the prevalent interpretations within that tradition, it attempts to show that the skepticism conveyed in the episode is more radical than it has been conceived, such that the episode can be read as a skeptical response to Descartes' refutation of skepticism based on the _Cogito, ergo sum_ proof. The paper explains how the lack of commitment in Zhuangzi to the dubious assumption (...) about 'I' that it necessarily refers to something existing to which Descartes seems to uncritically adhere allows Zhuangzi to doubt what for Descartes is absolutely indubitable: _I exist_. (shrink)

Zhuangzi’s Butterfly Dream story can be read as a skeptical response to the Cartesian Cogito, ergo sum solution, for it presents I exist as fundamentally unprovable, on the grounds that the notion about “I” that it is guaranteed to refer to something existing, which Descartes seems to assume, is unwarranted. The modern anti-skepticism of Hilary Putnam employs a different strategy, which seeks to derive the existence of the world not from some “indubitable” truth such as the existence of myself , (...) but from the meaning of some particular assertion I make. In this paper, I argue, however, that Putnam’s argument fails to deliver on the promise of showing the self-refuting nature of the skeptical hypothesis, as it relies on a double use of “I”, a fallacy of equivocation, reflecting an unsolved tension between the argument’s general premise, which is rather Zhuangzian in spirit, and his unwitting adoption of that unwarranted notion about “I”. I try to show further that the skepticism in Zhuangzi’s Butterfly Dream not only can be used to refute the proofs of the existence of the empirical I , but also is effective against accounts concerning the existence of the transcendental I.

Selflessness can be considered on an epistemic, on a moral, and on a historical level. The article follows recent thoughts by Jay L. Garfield on the idea that conceiving of oneself as a substantive self means following an illusion. It investigates the different senses of “illusion” and asks what it could mean for individuals and societies tobe transformed in such a way that this illusion would not play a role anymore.

The aim is to fashion intuitive conditions of pragmatic consistency for the speech act of assertion into a formal theory, so as to exclude "pragmatically absurd" utterances (contradictory statements, versions of the liar, moore's paradox, etc.). a core theory i for a concept of pragmatic implication (tentatively identified with overt or covert assertion) and an added theory ib for implied belief are constructed on the pattern of a weak modal system, whose specific axiom is taken to explicate what it means (...) to perform a binding speech act. a model-theoretic interpretation is given. a theory of declarative expressions provides a bridge from ib to the desired results for explicit assertion.

In this paper, I aim to address a specific issue underpinning Cartesian metaphysics since its first public appearance in the Discourse right up until the Meditations, but which definitely came to the surface in the Second and Fifth Replies. It involves the possibility that to be thinking and to be extended do not actually contrast as two entirely different properties; hence, these two essences cannot serve as the basis for a disjunctive, real distinction between two corresponding substances, the mind and (...) the body. I dub this problem the ‘thinking matter issue.’ I suggest that Descartes’s concerns about the ‘thinking matter issue’ characterizes and structures the entirety of Meditation Two and its connection with Meditation Six, especially in the attempt to covertly implement what I refer to as Descartes’s ‘prejudice strategy.’ The core of the ‘prejudice strategy’ lies in the idea that the ‘thinking matter issue’ is just a false problem, one raised by the inadequate notions of the mind and the body that we apply to this problem. In section 1, I set out the way in which the ‘thinking matter issue’ emerged in Descartes’s philosophy after the first exposition of his metaphysics in the Discourse. Section 2 deals with the new argumentative path Descartes draws for the Meditations and with the new role that he assigns to the inference about the mind’s non-physical nature after the cogito. In section 3, I contend that the ‘prejudice strategy’ structures Meditation Two and, partially, Six. Section 4 shows that Descartes himself reveals this in his Replies to the Second and the Fifth Set of Objections. In section 5, I delve into Descartes’s foundational theory of the ‘prejudice strategy,’ i.e. his theory of infancy as set out especially in the Replies to the Sixth Set of Objections. -/- . (shrink)

This paper deals with some formal properties of objects that are supposed to be internal to persons, that is, mental structures and mental functions. Depending on the ways of talking about these internal objects, they will appear different. Two types of discourse will be presented, to be called the realist and the nominalist discourses, and for eachdiscourse I will focus upon the construction of `self'.The realist discourse assumes an identity between the person and his construction of himself. I will illustrate (...) this discourse in terms of Descartes' ideas on himself as a `thinking substance'. The nominalist discourse assumes an impossibility to attain this identity, and instead to imply a complementarity between the person and his self-construction. I will illustrate this discourse in terms of the problems both William James and Sartre discerned when a conscious person chases after his own consciousness (termed `judging thought' and `pour-soi' respectively).

Descartes’s meditator thinks that if she does not know the existence of God, she cannot be fully certain of anything. This statement seems to contradict the cogito, according to which the existence of I is indubitable and therefore certain. Cannot an atheist be certain that he exists? Atheistic knowledge has been discussed almost exclusively in relation to mathematics, and the more interesting question of the atheist’s certainty of his existence has not received the attention it deserves. By examining the question (...) of atheistic knowledge in relation to the cogito, I articulate the advantage Descartes sees in having knowledge of God. I challenge a long-held reading of the cogito where “I exist” is the first full certainty and argue that while atheistic cogito is more certain than atheistic knowledge in mathematics, it cannot be a starting point for lasting and stable science, because science requires knowing the existence of the non-deceiving God.

In the Cartesian tradition of discussing the structure of the micro-judgement “I think” Kant‘s treatment deserves extraordinary attention. Under the idiomatic heading of self-affection he delivers a micro-analysis of this judgment, contributing in a unique way to the clarification of a singular case of self-knowledge: In this case the thinking subject 1. thematises the act of judging “I think” by conferring on this act the specific logical, categorical form, 2. intuits this act under the temporal form of successively using “I...” (...) as subject and “… think” as predicate, 3. identifies him-/herself — at the same time — with the subject logically structuring this act as well as with the subject intuiting the successively existing subject of this judging act, and 4. recognises him-/herself as identical in these two different cognitive roles. By this very analysis Kant shows that the eminent micro-judgement-act “I think” has the complex, though paradigmatic substructure of each human subject recog­nising his/her identity as thinking / judging and temporally existing while thinking / judging.

I am aware of the rain outside, but only in virtue of looking at a weather report. I am aware of my friend, but only because I hear her voice through my phone. Thus, there are some things that I’m aware of, but only indirectly. Many philosophers believe that there are also some things of which I am directly aware. The most plausible candidates are experiences such as pains, tickles, visual sensations, etc. In fact, the philosophical consensus seems to be (...) that experiences are the only plausible candidates for acquaintance. But I will argue that we are also acquainted with ourselves. After outlining what it means to be acquainted with oneself, I will introduce, develop, and defend a commonly used test for acquaintance. Then I will apply this test to us and show that we pass. I will consider various objections to my argument. But ultimately I will conclude that we can be, and often are, acquainted with ourselves.

ABSTRACT E. M. Curley has said that Descartes’ cogito, ergo sum “is as obscure on examination as it is compelling at first glance.” Why should that be? Maybe because the cogito raises so many textual and interpretive questions. Is it an argument or an intuition? If it is an argument, does it require an additional premise? Is it best interpreted as a “performance?” Is it best seen as the discovery that any reason proposed for doubting its success entails the meditator’s (...) existence? And so on. But all these questions typically arise in the wake of worries about the cogency of the cogito when it is treated as an argument and worded in its canonical form, “I think, therefore I exist.” In this essay, I focus on what I take to be the most fundamental reason for questioning the cogito’s cogency when it is so treated—namely that the “I” in its premise is question-begging. I distinguish that reason from other reasons that are sometimes conflated with it, and I argue that it is not a good reason. I then comment on some of the questions mentioned above in light of my defense of the cogito seen in that traditional way. (shrink)

Con excepción de Aristóteles, no hay quizá ningún otro filósofo al que Hegel se haya referido repetidamente en forma tan elogiosa como Descartes. Descartes es para Hegel quien por primera vez en la Historia de la Filosofía, antes que Fichte, advierte que la autoconciencia es un momento esencial de la objetividad del conocimiento humano y convierte así a la actividad como tal del pensar en principio fundamental de la filosofía. La introducción de este nuevo paradigma, a saber: el idealista, implica (...) una verdadera revolución teórica, cuyos corolarios los autores posteriores a Descartes intentan explicitar. En el contexto de este proceso de explicitación, Hegel - a primera vista, curiosamente - contrapone el pensamiento de Kant al de Descartes: si bien, por un lado, profundiza el modelo idealista, Kant, por el otro, hipostasia a ojos de Hegel el representacionalismo y, con ello, los elementos realistas presentes en el idealismo cartesiano. Para Hegel, la absolutización del principio idealista propuesto por Descartes significa, por el contrario, un retorno al espíritu genuino de su pensamiento. El idealismo absoluto se entiende, en efecto, como la consumación de un modelo teórico novedoso en filosofía. Ahora bien, no sólo el verdadero sentido de este modelo, sino ante todo su potencialidad explicativa en relación a los problemas fundamentales de la filosofía han pasado frecuentemente inadvertidos. Mediante el análisis de algunas tesis centrales en su proceso de constitución, en nuestra comunicación intentaremos arrojar luz sobre la naturaleza del paradigma del idealismo absoluto y, sobre esta base, examinaremos su relevancia para la problemática filosófica del presente en el ámbito de la teoría del conocimiento y la ontología.

From the Editor’s Introduction: "The Internal Limitations of Human Understanding." We carry, unavoidably, the limits of our understanding with us. We are perpetually confined within the horizons of our conceptual structure. When this structure grows or expands, the breadth of our comprehensions enlarges, but we are forever barred from the wished-for glimpse beyond its boundaries, no matter how hard we try, no matter how much credence we invest in the substance of our learning and mist of speculation. -/- The limitations (...) in view here are not due to the mere finitude of our understanding of ourselves and of the world in which we live. They are limitations that come automatically and necessarily with any form of understanding. They are, as we shall see, part and parcel of any organization or ordering of data that we call information. -/- The consequences of these limitations are varied: As a result of them, hermeneutics cannot help but be hermetic; scientific theories of necessity are circumscribed by the boundaries of the ideas that define them; formal systems must choose between consistency and comprehensiveness; philosophical study, because it includes itself within its own proper subject matter, is forced to be reflexive in its self-enclosure. The fundamental dynamic shared by all forms of understanding testifies to an internal limitative keystone. (shrink)

-/- Human beings are conscious not only of the world around them but also of themselves: their activities, their bodies, and their mental lives. They are, that is, self-conscious (or, equivalently, self-aware). Self-consciousness can be understood as an awareness of oneself. But a self-conscious subject is not just aware of something that merely happens to be themselves, as one is if one sees an old photograph without realising that it is of oneself. Rather a self-conscious subject is aware of themselves (...) as themselves; it is manifest to them that they themselves are the object of awareness. Self-consciousness is a form of consciousness that is paradigmatically expressed in English by the words “I”, “me”, and “my”, terms that each of us uses to refer to ourselves as such. -/- A central topic throughout the history of philosophy—and increasingly so since the seventeenth century—the phenomena surrounding self-consciousness prompt a variety of fundamental philosophical and scientific questions, including its relation to consciousness; its semantic and epistemic features; its realisation in both conceptual and non-conceptual representation; and its connection to our conception of an objective world populated with others like ourselves.

Self-consciousness can be understood as the ability to think I-thou-ghts which can be described as thoughts about oneself ‘as oneself’. Self-consciousness possesses two specific correlated features: the first regards the fact that it is grounded on a first-person perspective, whereas the second concerns the fact that it should be considered a consciousness of the self as subject rather than a consciousness of the self as object. The aim of this paper is to analyse a few considerations about Descartes and Hume’s (...) approaches to self-consciousness, as both philosophers introduce a first-personal method of accessing the subjective dimension through an introspective account. Descartes’s view on self-consciousness seems incapable of conceiving and recognizing herself as herself, while Hume’s seems to lack those features assigned to the consciousness of self-as-subject.

This paper concerns the three great modal dichotomies: (i) the necessary/contingent dichotomy; (ii) the a priori/empirical dichotomy; and (iii) the analytic/synthetic dichotomy. These can be combined to produce a tri-dichotomy of eight modal categories. The question as to which of the eight categories house statements and which do not is a pivotal battleground in the history of analytic philosophy, with key protagonists including Descartes, Hume, Kant, Kripke, Putnam and Kaplan. All parties to the debate have accepted that some categories are (...) void. This paper defends the contrary view that all eight categories house statements—a position I dub ‘octopropositionalism’. Examples of statements belonging to all eight categories are given. (shrink)

Descartes’s Meditations on First Philosophy, regarded by many as his masterpiece, has been the subject of significant philosophical debate since its publication in 1641. Yet the Meditations is remarkable not only for its philosophical ideas but also for the style in which it was written. Two of the most notable stylistic elements of the Meditations are the use of temporal markers—a significant departure from analogous philosophical treatises of the same period—and the fact that the text is written in such a (...) way as to invite readers to subsume themselves into the role of the narrator, so as to experience its arguments for themselves. Many commentators have hinted at the importance of the narrator. But there has been little attempt at a sustained engagement. The function of the text as a series of days of meditation has also been insufficiently explored. In order to further investigate the roles of time and narrative within the Meditations, this thesis uses various reading methods provided by narrative theory, with particular focus on Monika Fludernik’s experiential model of narrative. Fludernik’s model allows for a clearer articulation of the role readers play in enacting meaning, and the way in which readers will in a sense “author” a text on their own terms. Reading the Meditations as an experiential narrative also illuminates significant issues to do with Descartes’s distinction between geometric and discursive argument, his conception of time, the specific expression of the Cogito in the Meditations, and the “reorientation” at the heart of the text—which I am calling a sort of conversion. The conversion at the heart of the Meditations will be explored in parallel with Saint Augustine’s Confessions and Saint Ignatius of Loyola’s Spiritual Exercises, two texts which—like the Meditations—can be thought of as experiential narratives designed to bring about some kind of conversion. I argue that such an experiential reading, drawing on the roles of time and narrative in the text, offers to enrich our understanding of the Meditations. (shrink)

Philosophical work on explanation has focused on the following two topics: theories of explanation, intended to enumerate necessary and sufficient conditions for explanation, and inference to the best explanation as the strongest form of justification for ontological or metaphysical claims. I critically examine the most important philosophical work in both of these areas and defend my own conclusions about the connections between explanation and ontology. I argue that all of our inferences about the nature of the world, in ontology or (...) metaphysics, presuppose criteria for acceptable explanation. I first examine the metaphysics of Plato, Aristotle, and Leibniz, arguing that their metaphysical reasoning was guided by assumptions about the nature of explanation. I also survey some recent work in ontology and find inference to the best explanation offered as the strongest available method of defending existence claims. To conclude this discussion, I offer an original argument for the thesis that all reasoning about existence claims, being nondeductive, presupposes some criteria for acceptable explanations, or a theory of explanation. Carl Hempel and Wesley Salmon have been two of the most influential philosophers offering theories of explanation, and I examine their work with the intention of discovering ontological or metaphysical assumptions shaping their theories of explanation. I argue that Hempel's theory rests on deterministic assumptions, and I argue the Salmon's theory of causality, which he admits supports his theory of explanation, is subject to empiricist criticisms. Theories of explanation typically rest on assumptions about the nature of the world, I argue, and I explain why this is so with an original theory of explanation connecting it to the psychological phenomenon of understanding. We rely on understanding in the identification of explanations, and understanding requires establishing a metaphysical context for an explanandum-event. I end by indicating the possibility of generating vicious justificatory circles through the reciprocal relationship of support between explanation and ontology, and I argue that vicious circles can be avoided only by grounding all ontological reasoning in a fundamental explanatory task of giving order to experience through a system of categories.

I offer a novel reading in this dissertation of René Descartes’s (1596–1650) skepticism in his work Meditations on First Philosophy (1641–1642). I specifically aim to answer the following problem: How is Descartes’s skepticism to be read in accordance with the rest of his philosophy? This problem can be divided into two more general questions in Descartes scholarship: How is skepticism utilized in the Meditations, and what are its intentions and relation to the preceding philosophical tradition? -/- I approach the topic (...) from both a historical and a text-based analysis, combining textual and contextual research. I examine Descartes’s skepticism against two main traditions in the historical analysis: philosophical skepticism and Aristotelian Scholasticism. I argue that skepticism in the Meditations is intended to oppose and upheave both Scholasticism and skepticism. The intended results of the work are not merely epistemological but also metaphysical and even ethical. Furthermore, these ambitions cannot be neatly distinguished but merge into each other. -/- The third historical context against which the skeptical meditations are examined is the literary genre of meditative exercises, particularly from the 1500–1600’s, which, while religiously and spiritually oriented, likewise provided the practitioner with an enlightened understanding of self-knowledge and their cognitive place in the world on the way to closer spiritual proximity to God. I argue by this reading that the skepticism of the Meditations is an attentive, meditational cognitive exercise that is not merely instrumental and methodological but is to have a genuine and serious (psychologically real) effect on our thinking. The skeptical meditation is not simply a theoretical thought experiment but is to be seriously practiced as a transformative process of reorienting one’s cognitive framework to discover truth, certainty, and a way to a happy, tranquil, and virtuous life. -/- I offer a close reading in the textual analysis of the first three meditations of the Meditations. I argue that the meditative skepticism employed in the work does not reject the previous beliefs but suspends judgment on them, withdrawing assent until further evidence can be found. I introduce a new term into Descartes scholarship in this analysis, based on the terminology of ancient skepticism: Cartesian epochē (gr. epochē, suspension, withdrawal). Instead of rejecting previous beliefs or assenting to the probably false, the skeptical procedure of the Meditations is argued to emulate in important ways the suspension of judgment on equally balanced reasons in ancient Pyrrhonian skepticism. Novel interpretations are presented along the way of the will’s freedom, of the First Meditation’s skeptical scenarios, of the cogito, and of the vindication of metaphysical certainty, as well as a clarification of the Cartesian Circle problem. -/- Reinterpreting the relation of Descartes’s skepticism to the preceding historical and literary traditions leads to a new look at the skeptical method itself. Presenting a new interpretation of skepticism in the Meditations leads at the same time to a new look at its relation to the historical context. The two research questions are, then, intrinsically tied together. -/- My focus in the study is on the Meditations, but I also reference and discuss Descartes’s other philosophical works, as well as his correspondence, when necessary.

This paper is devoted to defending philosophical studies of mind, especially traditional ones. In my view, human mentality is a dialogue with myself, which has a social aspect that is never explained nor predicted by scientific studies. We firstly derive this picture from Descartes’ classical argmuments (§§2-3), and then develop it in the context of Kantian ethics (§4). Some readers think this combination arbitrary. However, these two philosophers agree on mind/body dualism (§5), and further, the fact that the dialogue is (...) often made in an ethical situation leads us to Kantian ethics. We shall draw this developed picture within the format of modern practical syllogisms (§§5-13). Finally, we shall refer to Nick Zangwill’s normative essentialism for the completion of our whole picture (§§7-8). (shrink)

The relevance of any logical analysis lies in its ability to solve paradoxes and trace conceptual troubles back; with this respect, the task of epistemic logic is to handle paradoxes in connection with the concept of knowledge. Epistemic logic is currently introduced as the logical analysis of crucial concepts within epistemology, namely: knowledge, belief, truth, and justification. An alternative approach will be advanced here in order to enlighten such a discourse, as centred upon the word assertion and displayed in terms (...) of utterance. Insofar as epistemic modalities express some attitudes, the intentionality of discourse will be emphasized within an illocutionary modal logic. Two large views will range over the whole study: declarative and epistemic sentences have one and the same logic (assertion logic); the plurality of languages games doesn’t entail any logical pluralism. -/- La valeur d'une analyse logique réside dans sa capacité à résoudre des paradoxes et à comprendre l'origine de nos problèmes conceptuels ; à ce titre, le rôle d'une logique épistémique est de traiter des paradoxes liés au concept de connaissance. On présente généralement la logique épistémique comme une analyse logique de concepts centraux en épistémologie : connaissance, croyance, vérité, justification. Une autre approche sera proposée ici en vue de clarifier ce genre de discours, centrée sur la notion d'assertion et décrite en termes d'énonciation. Parce que les modalités épistémiques expriment des attitudes, c'est l'intentionnalité du discours qui sera mise en valeur dans le cadre d'une logique modale illocutoire. Deux thèses transversales parcourront l'ensemble du travail : les énoncés déclaratifs et épistémiques partagent la même logique (logique assertorique) ; la pluralité des jeux de langages n'implique pas un pluralisme logique.

Subjectivity is that feature of consciousness whereby there is something it is like for a subject to undergo an experience. One persistent challenge in the study of consciousness is to explain how subjectivity relates to, or arises from, purely physical brain processes. But, in order to address this challenge, it seems we must have a clear explanation of what subjectivity is in the first place. This has proven challenging in its own right. For the nature of subjectivity itself seems to (...) resist straightforward characterization. In this paper, I won't address how subjectivity relates to the physical. Instead, I'll address subjectivity itself. I'll do this by introducing and defending a model of subjectivity based on self-acquaintance. My model does not purport to reduce, eliminate, or naturalize subjectivity, but it does make subjectivity more tractable, less paradoxical, and perhaps less dubious to those averse to obscurity.

The main aim of this article is to pose and consider the following question: Does the reasoning that led to Kripkenstein’s sceptical paradox undermine all versions of materialism, including nonreductive materialism? First, I present other versions of materialism in the philosophy of mind. Then I point out that, according to nonreductive materialists, one can neither define mental properties in terms of physical properties nor derive psycho‑physical laws from the laws of physics. The presently‑understood thesis of materialism is confined by the (...) following claim: the same distribution of physical properties entails the same distribution of mental properties. In other words, the mental properties supervene upon physical properties. This account then leads to the following formulation of the main question: Assuming that Kripkenstein is right, do mental properties supervene upon physical properties? Taking into account that answering this question requires a discussion of the notions of supervenience and Kripkenstein’s paradox, I devote two parts of my paper to these topics. The conclusion which I reach is as follows: If the reasoning that led to Kripkenstein’s paradox is correct, mental properties can only globally supervene upon physical properties, and consequently no version of materialism can be empirically justified.

In this study, I propose a reading of Derrida as a Cartesian thinker. The mode of reading is closely textual and not historical; and the analysis focuses on the methodological or dispositional affinities between a sceptical Descartes in cogitation and a deconstructive Derrida, to the exclusion of the onto-theological aspects of their arguments. I locate the source of such epistemological affinities between them in the self-reflexivity of philosophical self-doubt or self-criticism, and highlight, in the course of analysis, the formatively self-referential (...) aspects of both Cartesian scepticism and Derridian deconstruction; The point of contention is that, in both cases, the starting point of thinking is the self that self-reflects. Standard interpretations tend to view Derrida as an anti-Cartesian thinker; Against this reading, I advance the following two points of contention. Firstly, I argue that Derrida can be read as a Cartesian thinker in that his reflexive tendency is indicative of his implicit commitment to the methodological or epistemological Cartesianism, i. e. the reflexive mode of cogitation. The claim here, limited to such an extent, is that there is a structural resemblance between the reflexive form of Descartes's cogilo and that of Derrida's deconstructive move in that both thinkers follow performatively reflexive, and reflexively repeated moves; The Derridian move is only one "step" beyond, and in this sense derivative from, the Cartesian. Secondly, I argue further that Derrida can be read as a radical Cartesian. For this, I present a reading of Derrida's reflexive hauntology as a sceptical radicalisation of Descartes's reflective ontology. By bringing to the fore a structurally Cartesian dimension which underlies the Derridian economy of writing and thinking, I argue, against Derrida's self-understanding of his (non-)project, that deconstruction is to be read as a conservative intra-metaphysical trajectory rather than as a transgressive endeavour to go beyond metaphysics. In highlighting the traditional aspects of deconstruction as opposed to the revolutionary sides of it, my aim is both to explicate the significance of Derrida's deconstructive project and, at the same time, to expose its constitutive limits, deconstruction taken as a meta-critical, reflexive endeavour to transcend the limits of philosophy by philosophy. The critical point I raise against Derrida is the following: Insofar as the logic or strategy of his deconstruction remains structurally locked in, and at the same time exploitative of, the implicit binarism of Cartesian scepticism, i. e. the logic of either-or, the deconstructive gesture that attempts to think "the Other" by reflecting critically upon its own condition of thinking, is bound to be self-reflexive or self-referential, therefore, self-corrosively ineffectual. Part I sets out to articulate the aforementioned two contentions of thesis. It aims to discover the recursively self-reflexive movements in the writings of Derrida. For this, chapter 2 offers an analysis of some of Derrida's central terms of hauntology that are descriptive of the movements and moments of meta-reflection, viz. double, mark, fold, interest, and law. Although Part I deals mainly with Derrida, the reflexive dimension of Descartes's cogito argument is also analysed in an early stage [1.31] to the extent that it can set the terms for the subsequent reading of Derrida as a Cartesian [1.32 -2.3]. Part II elaborates the key points made in Part I, first by providing a detailed account of the Cartesian economy of self-reflexivity [Chapter 4], and second, by closely reading selected passages from Den ida's essay on Descartes, 'Cogito et histoire de lafolie' [Chapter 5]. Derrida's defensive and sympathetic reading of Descartes's madmen against Foucault's, the last chapter argues, exemplifies a case of Derrida as a committed Cartesian with a mind bent on methodic meta-reflection.

The thesis includes six essays, each corresponding to a chapter, which have the target of widening the discussion on the limits of knowability through the consideration of some general problematics and the discussion of specific topics. The work is composed of two parts, each of three chapters. In the first part, the discussion is focused on a perspective proper of the philosophy of language. In particular, I consider the discussion on the limits of knowability from the point of view of (...) the debate between semantic realism and antirealism. The second part of the thesis is focused on the discussion on the limits of knowability from a perspective more strictly epistemological and proper of the philosophy of science. (shrink)

This article presents a novel reading of Descartes’s critique of the traditional syllogistic. The reading differs from those previously presented by scholars who regard Descartes’s critique as a version of a well-known argument: that syllogisms are circular or non-ampliative and thus trivial. It is argued that Descartes did not see syllogisms as defective in themselves. For him the problem was rather that anyone considering a valid and informative syllogism must already know, by an intuition wholly independent of the syllogism, that (...) the conclusion follows from the premises. Moreover, without such an intuition the syllogistic on its own is incapable of determining whether the consequence truly holds. Thus the syllogistic is useless unless accompanied by an intuition that renders it otiose. This reading of Descartes’s view is supported and explained by examples drawn from Descartes’s writing and from the Port-Royal Logic—one of the first attempts to develop a logical system on Cartesian principles.

The problem of philosophical skepticism relates to the difficulty involved in underwriting the claim that we know anything of spatio-temporal reality. It is often claimed, in fact, that proper philosophical scrutiny reveals quite the opposite from what common sense suggests. Knowledge of external reality is thought to be even quite obviously denied to us as a result of the alleged fact that we all fail to know that certain skeptical scenarios do not obtain. A skeptical scenario is one in which (...) we have neurological occurrences just like any normal situation in which we actually perceive spatio-temporal objects, but where we are deceived in some sense as a result of the manipulation of our brains from some outside source. In this work I attempt to address the problem of philosophical skepticism by claiming that most of us are able to come to know plenty about external reality, since we can come to realize that a certain philosophical theory of perception is correct. The theory I have in mind is what I call a non-cognitive theory of perception. According to this view, perceptual experience is defined by continuous, sensitive behavioral interaction with spatio-temporal objects of the appropriate size, shape, hardness, speed, etc. Knowing that this theory of perception is correct is equivalent to knowing that we know plenty about external reality. This is ultimately because by knowing that a non-cognitive theory of perception is true, we know that any skeptical scenario must fail to obtain. The structure of the work proceeds by first discussing the significance of the problem of philosophical skepticism in some detail. Chapter 1 lays out how the problem does indeed forcefully arise if it is conceded that we fail to know that the skeptical scenarios fail to obtain. Chapter 2 develops the sort of view of our epistemological situation that falls out of accepting without qualification that the problem exists. Chapter 3 examines and criticizes certain popular responses to the skeptical problem. The main goal of these first three preliminary chapters is to indicate that once it is admitted that we fail to know that the skeptical scenarios fail to obtain, the problem of philosophical skepticism forcefully presents itself. Chapter 4, however, attacks the idea that we fail to know that the skeptical scenarios fail to obtain. In this chapter I argue that this idea is wedded to the position that a certain theory of perception is correct. The theory in question is what I call a conjunctive theory of veridical experience. According to this view, normal experience of spatio-temporal objects occurs when a subject has a certain perceptual experience, and that experience also happens to match up with and/or be satisfied by what is really the case. Only when a theory of this sort is assumed, I argue, is the claim that we fail to know that the skeptical scenarios fail to obtain found to be obvious. In chapter 5 I argue that, in fact, a non-cognitive theory, rather than a conjunctive theory, is the correct view to maintain. In the final chapter 6 I develop the epistemological position that falls out of accepting a non-cognitive theory. (shrink)

The Knowability Paradox is a logical argument that, starting from the plainly innocent assumption that every true proposition is knowable, reaches the strong conclusion that every true proposition is known; i.e. if there are unknown truths, there are unknowable truths. The paradox has been considered a problem for every theory assuming the Knowability Principle, according to which all truths are knowable and, in particular, for semantic anti-realist theories. A well known criticism to the Knowability Paradox is the so called restriction (...) strategy. It bounds the scope of the universal quantification in (KP) to a set of formulas whose logical form avoids the paradoxical conclusion. Specifically, Tennant suggests to restrict the quantifier in (KP) to propositions whose knowledge is provably inconsistent. He calls them Anti-Cartesian propositions and distinguished them in three kinds. In this paper we will not be concerned with the soundness of the restriction proposal and the criticisms it has received. Rather, we are interested in analyzing the proposed distinction. We argue that Tennant’s distinction is problematic because it is not completely clear, it is not grounded on an adequate logical analysis, and it is incomplete. We suggest an alternative distinction, and we give some reasons for accepting it: it results logically grounded and more complete than Tennant’s one, inclusive of it and independent from non-epistemic notions.

Much ado has been made regarding Descartes's understanding of the creation of what he called the "eternal truths" because he described them, paradoxically, as both the free creations of God, and necessary. While there are many varying interpretations of Cartesian modality, the issue has heretofore been treated in a vacuum, as a niche issue having little import beyond being an interesting puzzle for Descartes Scholars. I argue that this treatment is misguided, and that in order to properly understand Cartesian philosophy (...) at all, one must properly understand Descartes's theory of modality. This, however, is no small feat; in order to understand Descartes's seemingly peculiar view on modality, one must first make sense of what Descartes understood the nature of God to be. One reason for this, I argue, is the systematic nature of Cartesian philosophy; indeed when dealing with a dense inter-connection of philosophical issues, one must move from what is more known in itself to what is more known to us, and not the other way around. I argue that in the literature on Cartesian modality, insufficient attention has been paid to the influence of the French School of Spirituality on the Cartesian notion of the divine. I argue that this influence pushed Descartes to criticize traditional attempts to split the horns of Plato's Euthyphro dilemma as violating a proper understanding of the doctrine of divine simplicity. Descartes's commitment to a radical form of the doctrine of divine simplicity leads him to a version of divine voluntarism wherein all `things' depend on God for their existence, and God cannot have had antecedent reason to prefer the creation of anything over anything else. There is little doubt that Descartes embraced the voluntarist horn of the Euthyphro dilemma, but just what that means for Cartesian modality and philosophy generally remains a contentious issue. I argue that Descartes is best read as what I call an `agnostic quietist' regarding God given textual, historical, and systematic considerations. One virtue of an agnostic quietist reading is that I am able to square the passages where Descartes discusses the inconceivability of God's power with the conclusions reached regarding God's non-deceiving nature in the Meditations and elsewhere. Further virtues that I explore are the effects that a quietist reading has on the Cartesian scientific programme, the infamous mind-body problem, Descartes's seemingly inconsistent view regarding human free-will and Descartes's refusal to engage in "theology." Traditionally, Cartesian epistemology has been understood to be a purely a priori undertaking, which succumbs to deep and insurmountable problems. One of the greatest problems facing the Cartesian was the move from the mind to the world. Simon Blackburn, for example, says of the Cartesian epistemological project in the Meditations that Descartes "has put himself on a desert island from which there is no escape." This view is echoed by, and even motivates some of the contemporary views concerning Cartesian modality. I argue, however, that a proper understanding of the Cartesian doctrine of clear and distinct ideas circumvents this famous problem. By highlighting the proper understanding and application of the doctrine of clear and distinct ideas, I show that such ideas not only guarantee the existence of an external truth-maker, but also that such ideas do not do much more than show that there is a truth-maker. I argue that in instances of clear and distinct perception, the truth of the idea is normatively certain, but what makes it true is yet to be established. In this way, clear and distinct ideas are both powerful, in terms of guaranteeing truth, and relatively unhelpful, in that further work is required in order to determine to what the ideas conform. I argue that this is the case not only for actual truths, but for some clearly intuited truths about possibility. As an illustration of my overall thesis, I address the Cartesian argument for the separability of mind and body, and entertain the various interpretations of Descartes's view of human freedom. I argue that in order to understand Cartesian views on either of these issues, one must first make sense of his modal commitments. In both of these cases Descartes claims that finite minds can know that something is possible, even though what makes it possible is well beyond what they can understand. (shrink)

The aim of this thesis is to investigate the role that the imagination plays in the later philosophy of René Descartes. The thesis will look at two related questions: the status of the imagination as a mode of thought dependent on the body; the role of the imagination in object-perception. Throughout, the traditional view of Descartes as a Cartesian Dualist is rejected and a more holistic approach is taken towards the relationship between mind and body, in which Descartes’ claims that (...) the two make up a “substantial union” are taken seriously. Part One deals with the relationship between mind and body. I argue that Cartesian Dualism cannot account for the faculties of sensation and imagination, because they have a corporeal basis. However, the ‘union of mind and body’, Descartes’ device for explaining their interaction, can. I end Part One by identifying a problem with the paradigm case of mind-body interaction, object-perception. To determine the object of an idea there needs to be a mechanism to marry the two ingredients of perception: the innate ideas of geometry in the intellect, and ‘adventitious’ ideas of the object delivered by the senses. Otherwise we have no explanation for how the essentially ‘inward-looking’ intellect can apply its ideas to the essentially passive sensations. Part Two focuses on the imagination and the question of object-perception raised in Part One. I argue against the largely-held view in the secondary literature that, with the advent of the cogito, the imagination’s cognitive profile declined sharply. I argue that, in fact, the corporeal basis of the imagination places it beautifully to bridge the gap in object-perception, and that this is part of its role in all Descartes’ discussions on the topic. The other, related, role of the imagination is to conjure fictions and hypotheses, suiting it for scientific and epistemological endeavours. The fact that the imagination is not tied to what is present to the senses, even though it receives its original content from them, means that it can manipulate ideas of corporeal things; including the innate notions of extension, shape and motion so key to gaining a clear and distinct idea of matter.

Descartes understood the subject matter of physics (or natural philosophy) to encompass the whole of nature, including living things. It therefore comprised not only nonvital phenomena, including those we would now denominate as physical, chemical, minerological, magnetic, and atmospheric; it also extended to the world of plants and animals, including the human animal (with the exception of those aspects of the human mind that Descartes assigned to solely to thinking substance: pure intellect and will). Descartes wrote extensively on physiology and (...) on the physiology and psychology of the senses. This chapter examines the notions of *physiology* and *psychology* in medical and natural philosophical works of Descartes' day; follows his efforts to bring physiology into his mechanistic idiom; considers the relation between physiology of the animal machine and psychological functions that yield functionally appropriate behavior; goes into his physiology and psychology of vision; and elaborates the tension in Descartes' works between his metaphysically supported micro-corpuscularism and his discussion of the animal machine as an organic unity comprising various functionally and teleologically characterized systems. The chapter draws on Descartes' works in both metaphysics and natural philosophy, including his Treatise on Man (originally published as L'Homme, 1664). (shrink)
