In virtue of what does a sign have meaning? This is the question raised by Wittgenstein's rule-following considerations. Semantic dispositionalism is a (type of) theory that purports to answer this question. The present paper argues that semantic dispositionalism faces a heretofore unnoticed problem, one that ultimately comes down to its reliance on unanalyzed notions of repeated types of signs. In the context of responding to the rule-following paradox—and offering a putative solution to it—this amounts to simply assuming a solution to (...) the problem in one domain and using it to solve the same problem in another. Given, moreover, the level at which the rule-following paradox undercuts dispositionalism—the level of the notion of a sign's repetition—the objections made to the view also rule out causal/informational theories of meaning as well as communitarian/assertion-theoretic ones as potential solutions to the rule-following paradox.

To date, film scholars have found the films of Jim Jarmusch to be tantamount to works of postmodern philosophy. For as intriguing and productive as such interpretations of Jarmusch’s films have been, I submit that the postmodern framework occludes a crucial aspect of Jarmusch’s film-philosophy, namely, his investment in the ordinary. From this perspective, I intend to show the availability of Jarmusch’s films to Wittgensteinian interpretation. More specifically, I plan to situate Jarmusch’s arthouse action film Ghost Dog: The Way of (...) the Samurai (1999) between Ludwig Wittgenstein and Jacques Derrida in order to demonstrate the profound affinities between Jarmusch’s film-philosophy and Wittgenstein’s conception of ordinary language. Through a consideration of character dialogue, I will demonstrate the extent to which Jarmusch rejects the private language argument – which, by extension, amounts to a rejection of linguistic relativism as an instance, or species, of skepticism – in favor of ordinary conceptions of language, expressiveness, knowledge, and responsibility.

The thesis of self-elusiveness says, roughly, that the self fails to be phenomenally manifest from the first-person perspective. This thesis has a long history. Yet many who endorse it do so only in a very specific sense. They say that the self fails to be phenomenally manifest as an object from the first-person perspective; they say that self-experience is not a species of ‘object-consciousness’. Yet if consciousness outstrips object-consciousness, then we are left with the possibility that there is another sense (...) in which the self is phenomenally manifest. Alas, efforts to articulate just what this form of self-experience comes to—often a holy grail of sorts for those in, and influenced by, the phenomenological tradition—have remained stubbornly obscure. This essay attempts a partial remedy. Taking a cue from Bernard Lonergan, I suggest that self-experience, while not a species of object-consciousness, is nonetheless partially grounded in it. The result is a view that is compatible with self-experience being representational and relational, contra tradition. (shrink)

E.E.C. Jones’s early logical writings have recently been rescued from obscurity and it has been claimed that, in her works dating from the 1890s, she anticipated Frege’s distinction between sense and reference. This claim is challenged on the ground that it is based on a common but inadequate reading of Frege, which runs together his concept/object and sense/reference distinctions. It is admitted that a case can be made for Jones having anticipated something very like Frege’s analysis of categorical propositions, and (...) that she offered a sound rebuttal of Russell’s objection to Frege’s account of the informativeness of identity statements. However, these significant achievements should not be misrepresented as an anticipation of Frege on sense and reference, a claim that encourages a defective reading of both philosophers. (shrink)

Metaphysicians are in the business of making and defending modal claims—claims about how things must, or could or could not be. Wittgenstein’s opposition to necessity claims, along with his various negative remarks about ‘metaphysical’ uses of language, makes it seem almost a truism that Wittgenstein was opposed to metaphysics. In this paper I want to make a case for rejecting that apparent truism. My thesis is that it is illuminating to characterize what Wittgenstein and Anscombe are doing in their philosophical (...) writing as metaphysics without manufactured necessities. Doing so helps to articulate a sharper, more interesting, critique of contemporary metaphysical practices than therapeutic or linguistic framings of Wittgenstein’s method make possible. It also allows us to place Anscombe in the context of a tradition of British metaphysics that emerged in the 1940s in an attempt to reverse the devastating impact on ethics of the new ‘analytical’ philosophy.

This essay—a contribution to the Common Knowledge symposium on contextualism—is concerned with the gradual rise of awareness of the existence of modes of thought or systems of belief that are different from those that are dominant in one's own culture. The awareness can be found in the seventeenth and eighteenth centuries but was developed further in the early to mid-twentieth century. Its main consequence has been to encourage individuals to distance themselves from their own system—to criticize and change it.

Theology used to be the discipline that arbitrated and ‘said’ the truth. Some argued that its methodical engagement had to make it a search-driven experimentation with an inductive outlook intended at tracking truth through practice and praise, in short conversion. The empirico-formal sciences have sought canonical norms of knowledge away from any regimentation. Neopositivism had for a time entertained a fact-derived language and, as such, it banned metaphor as mingling problems by perpetuating the belief in entirely theoretical knowledge-terms. Here we (...) aim at putting together an examination of some of the reasons why a pluralistic epistemology has come to be adopted, and an attempt at finding pluralistic responses to that very idea through interdisciplinary comparison. This is the editors' (M. Fuller & A. Runehov) introduction: Philippe Gagnon asks the interesting question: Does pluralism itself need to be plural? He argues that neo-positivism has for some time now focused on using a fact-derived language, banning metaphoricity. He explores the reasons pluralistic epistemology came to be adopted, and leads us through some important philosophical problems and how they were tackled by different philosophers and in various times. Such philosophical problems or questions concern theories, truth and knowledge. If a theory is considered to be the best one, on which criteria is this judgement made? Might it be better to have several theories that are ex æquo? Gagnon argues that even though ‘pluralism’ is a better term compared to ‘the many’, it does not entirely escape relativism. Hence, he proposes to use ‘plurality’ instead, which does not threaten the unity of truth. After this philosophical exploration, he turns to theology, specifically Trinitarian theology, to implement his findings there. (shrink)

According to Wittgenstein's Tractatus Logico-Philosophicus, propositions of natural science are all meaningful propositions of language therefore there is no ethical proposition because alleged ones do not fulfil the criterion of meaningfulness of propositions, which is empirical verifiability. In addition, Wittgenstein somewhere considers Tractatus Logico-Philosophicus to have an important ethical point. There seems to be a conflict between Wittgenstein's recent claim, on the one hand, and the meaninglessness of ethics, on the other. In the face of this apparent conflict, we try (...) to ponder the question of what is the ethical point of Tractatus Logico-Philosophicus. In answer to this question, we will pay attention to Kevin Cahill's interpretation of Wittgenstein. In Wittgenstein's view, modern culture prevents what he calls the experience of the wonder of the world. Cahill interprets the ethical point of Tractatus Logico-Philosophicus in connection with Wittgenstein's view on modern culture. What objection would Tractatus Logico-Philosophicus be subject to if Cahill's interpretation were correct? How defensible is the dependence of Cahill's interpretation of Tractatus on other Wittgenstein's works? At the end of our study, we will answer these questions. (shrink)

Will is a very old important philosophical concept, an analysis of which is very specific, if not odd, comparatively with the others. This concept is going to be used to provide and clarify conditions of possibility for person of being an agent. In doing that I refer to the correspondent pieces of Wittgenstein’s Tractatus and Philosophical In ves tigations; and to their interpretations by M. Alvarez in “Wittgenstein on Action and Will” and D. K. Le vy in “Morality without Agency”. (...) Person is essentially constituted by ‘powerless’ will in terms of ‘understanding’ that is experienced during her life. Action depends on and manifests understanding by will of a personal attitude to some states of affairs. Will does not incline a person to particular desires about preferable states of affairs or actions. Will is not about states of affairs. By willing I value the world, its portions, they appear significant, important to me. Volition is treated as related to will. Both are personal conditions of being an agent with priority of agency as capacity realized by rational actions. (shrink)

In her recent book, A Different Order of Difficulty, Karen Zumhagen-Yekplé uses a resolute reading of Wittgenstein’s Tractatus Logico-Philosophicus to highlight similarities between Wittgenstein’s work and his contemporaries Virginia Woolf, James Joyce and Franz Kafka. On the basis of this reading, she claims that Wittgenstein’s early masterpiece is a modernist work. -/- This article argues that there are profound problems with the resolute reading that she offers, and it suggests that ‘traditional’ readings of the Tractatus survive the criticisms she makes (...) of them. Nonetheless, a case can still be made that Wittgenstein’s work is a modernist one, and it is a useful exercise to compare the Tractatus with modernist works from the 1920s. -/- Philosophical Investigations, Volume 45, Issue 3, Page 274-296, July 2022.

Many philosophers suppose that sometimes we think we are saying or thinking something meaningful when in fact we’re not saying or thinking anything at all: we are producing nonsense. But what is nonsense? An account of nonsense must, I argue, meet two constraints. The first constraint requires that nonsense can be rationally engaged with, not just mentioned. In particular, we can reason with nonsense and use it within that-clauses. An account which fails to meet this constraint cannot explain why nonsense (...) appears meaningful. The second constraint requires that nonsense does not express thoughts. An account which fails to meet this constraint undercuts the critical force of the concept of nonsense. I offer an account which meets both constraints. The central idea is that to be under the illusion that some nonsense makes sense is to enter a pretence that the nonsense is meaningful. (shrink)

I argue that the principal roles standardly envisaged for abstract propositions can be discharged to the sentences themselves (and similarly for the meanings or senses of words). I discuss: (1) Cognitive Value: Hesperus-Phosphorus; (2) Indirect Sense and Propositional Attitudes; (3) the Paradox of Analysis; (4) the Picture Theory of the Tractatus; (5) Syntactical Diagrams and Meaning; (6) Quantifying-in. (7) Patterns of Use. I end with comparisons with related views of the territory.

This paper addresses what I call ‘the constitutive question’ concerning the rules we follow: namely, what determines the standard for a rule's correct application. John McDowell has offered a putative ‘middle position’ between two extreme, unacceptable answers: empirical idealism, which takes the requirements of a rule in any given situation to be constituted by our reaction to the case; and hard platonism, which takes these requirements to be delivered by unvarnished reality as absolutely the simplest or most natural way to (...) carry on. Tellingly, however, McDowell's position is itself unacceptably idealist in his picture of the way in which we are ‘involved’ on the right-hand side of biconditionals such as, ‘“Diamonds are hard” is true if and only if diamonds are hard’.In response to this stultifying state of affairs, I suggest that McDowell has followed the empirical idealist and hard platonist in assuming that the requirements of a rule must be grounded by something else: something external to the rule, which mediates between the rule and the standard for its correct application. This assumption is false. What is more, one application of a metaphor to which Wittgenstein has a somewhat equivocal relation—that of rules as rails invisibly laid to infinity—can help this point to stick. (shrink)

In this article, I seek to assess the extent to which Theism, the claim that there is a God, can provide a true fundamental explanation for the existence of the infinite plurality of concrete and abstract possible worlds, posited by David K. Lewis and Alvin Plantinga. This assessment will be carried out within the (modified) explanatory framework of Richard Swinburne, which will lead to the conclusion that the existence of God provides a true fundamental explanation for these specific entities. And (...) thus, given the truth of this type of explanation, we have another good abductive argument for God’s existence and grounds for affirming a weaker form of the principle of methodological naturalism in our metaphysical theorising.

This book proposes a novel theory of truth and falsity. It argues that truth is a form of reference and falsity is a form of reference failure. -/- Most of the philosophical literature on truth concentrates on certain ontological and epistemic problems. This book focuses instead on language. By utilizing the Fregean idea that sentences are singular referring expressions, the author develops novel connections between the philosophical study of truth and falsity and the huge literature in in the philosophy of (...) language on the notion of reference. The first part of the book constructs the author’s theory and argues for it in length. Part II addresses the ways in which the theory relates to, and is different from, some of the basic theories of truth. Part III takes up how to account for the truth of sentences with logical operators and quantifiers. Finally, Part IV discusses the applications and implications of the theory for longstanding problems in philosophy of language, metaphysics, and epistemology. -/- A Referential Theory of Truth and Falsity will appeal to researchers and advanced students working in philosophy of language, epistemology, metaphysics, and linguistics. -/- .

According to methodological anti-exceptionalism, logic follows a scientific methodology. There has been some discussion about which methodology logic has. Authors such as Priest, Hjortland and Williamson have argued that logic can be characterized by an abductive methodology. We choose the logical theory that behaves better under a set of epistemic criteria. In this paper, I analyze some important discussions in the philosophy of logic, and I show that they presuppose different methodologies, involving different notions of evidence and different epistemic values. (...) I argue that, rather than having a specific methodology such as abductivism, logic can be characterized by methodological pluralism. This position can also be seen as the application of scientific pluralism to the realm of logic. (shrink)

ABSTRACT When enmity seizes language, speech needs be silenced to give meaningful communication a chance. But current Manichean structures making life a moral battleground have to first be undone to make shared problem solving possible. It is suggested that a rhetoric of the essay is better suited to this task than the rhetoric of speech.

Hybrid contingentism combines first-order contingentism, the view that it is contingent what individuals there are, with higher-order necessitism, the view that it is non-contingent what properties and propositions there are (where these are conceived as entities in the range of appropriate higher-order quantifiers). This combination of views avoids the most delicate problems afflicting alternative contingentist positions while preserving the central contingentist claim that ordinary, concrete entities exist contingently. Despite these attractive features, hybrid contingentism is usually faced with rejection. The main (...) reason for this is an objection that crucially involves haecceitistic properties, properties such as being identical to Plato or being identical to Aristotle. The objection alleges that by accepting the necessary existence of such haecceities, hybrid contingentists incur an explanatory commitment that they are unable to discharge, namely that of explaining how it is that certain haecceities ‘lock onto’ their target individuals even when those individuals are absent. To defend hybrid contingentism against this charge, I first clarify the haecceities objection in several respects and consider, in particular, what notion of explanation the objection is operating with. After arguing that it can be fruitfully understood as a challenge to provide metaphysical grounds for certain haecceity facts, I develop a contingentist response to the objection that draws on recent work on the connection between ground and essence.

Resulta extraño que tanto en las Investigaciones filosóficas como en la mayoría de los trabajos posteriores al Tractatus Logico-philosophicus Ludwig Wittgenstein no mencione explícitamente a la ética ni trate cuestiones relativas a ella. Teniendo esto en cuenta, en este texto quisiera ocuparme del lugar de las cuestiones éticas en la “nueva forma de orientar el pensamiento” desarrollada por Wittgenstein a lo largo de sus trabajos posteriores al Tractatus. El objetivo que orientará este texto será esbozar una concepción de la ética (...) en el pensamiento tardío de Wittgenstein, quien, a pesar de dedicar muy pocas líneas a estas cuestiones después del Tractatus, brinda elementos para desarrollar lo que podría ser una concepción ética en el marco de su pensamiento tardío. Con este fin, en primer lugar, caracterizaré a partir de la Conferencia sobre ética algunos aspectos centrales que deberían estar presentes en una concepción de ética en Wittgenstein. En segundo lugar, presentaré la nueva forma de pensar de Wittgenstein, que encuentra en las Investigaciones filosóficas su expresión más elaborada. En la última sección del texto intentaré articular de manera coherente con el pensamiento tardío de Wittgenstein los diferentes aspectos respecto a lo ético, que espero destaquen a lo largo de este escrito.

I argue that Carl Hempel’s pioneering work on scientific explanation introduced an assumption that Hempel never motivated, namely, that explanation is an aim of science. Ever since, it has remained largely unquestioned in analytic philosophy of science. By expanding the historical scope of the debate on explanation to philosophers from the first half of the twentieth century, I show that the debate should include a critical reflection on Hempel’s assumption. This reflection includes two problems: how to motivate one’s position on (...) the aims of scientific knowledge and how to decide which examples count as expressions of those aims. (shrink)

Here, we defend the thesis whereby the event plays a main role of sense in the meaning of certain sentences. This thesis is based on the one hand on recent work in the metaphysics of so-called “happening” entities, which has led to a distinction between concrete physical processes and abstract events, the latter being conceived as psychological constructs accounting for stabilities or changes in the world. Furthermore, we look back at the work on intentionality carried out in the Brentanian school (...) at the turn of the 20th century and we relate abstract events to the mental states of affairs studied by Twardowski but which were then neglected by contemporary philosophers of language. Abstract events, thus characterized, have the contingent property of occurring, when facts obtain and realize them. We suggest that the facts in question correspond to Wittgensteinian states of affairs. (shrink)

The author of the article focuses on the matter of Wittgenstein's philosophy reception in France. The reception of Wittgenstein's philosophy was quite late and led to different, sometimes opposite interpretations of his thought, even among French analytical philosophers. Applying a sociological approach to the problem of reception, the author identifies factors that hindered the penetration of the ideas of analytical philosophy in France, including the powerful institutionalization of philosophy in France with its inherent traditionalism and conservatism, fully expressed national character (...) of French philosophy, as well as the extremely polemical character of French analytical philosophy, the transformation of the choice of this tradition of philosophizing into an ethical and political choice. These factors are illustrated by an analysis of Wittgenstein's conflicting interpretation of Jacques Bouveresse and Sandra Laugier. If the first creates an image of Wittgenstein as Anti-Husserl, blaming the phenomenologist for ignoring ordinary language, the second proposes a phenomenological reading of Wittgenstein's ideas using the philosophy of ordinary language. The article shows how opposing interpretations of Wittgenstein's philosophy reproduce the internal conflicts of the French philosophical field. (shrink)

This essay offers an original interpretation and defense of the doctrine of flux, as it is presented in Plato’s Theaetetus. The methodology of the paper’s analysis is in the style of rational reconstruction, and it is highly analytic in scope, in the sense that I will focus on the text itself, and only on certain parts of it too, while ignoring the rest of Plato’s extensive corpus, and without worrying about whether, how, and to what extent the interpretation of the (...) view coheres well with the other elements of the secret doctrine view discussed in the dialogue, as well. In the first part of the essay, I’ll offer my interpretation of the doctrine. Then, in the second part of the essay, I’ll examine two potential criticisms of the doctrine, including Socrates’s infamous linguistic paradox, and show how my interpretation of Heraclitean flux metaphysics is able to circumvent both.

Some patterns call out for explanation, in the sense that we have a pro tanto reason to reject theories that do not give them an appropriate explanation. I argue that certain modal patterns call out for explanation in this way—and this provides a reason to reject certain theories of modality that fail to explain such patterns. However, I also consider a response to this argument, which claims that the modal patterns do not need explanation. This response might be viable but (...) it involves some substantial commitments about the nature of explanation. (shrink)

It is usually accepted that deductions are non-informative and monotonic, inductions are informative and nonmonotonic, abductions create hypotheses but are epistemically irrelevant, and both deductions and inductions can’t provide new insights. In this article, I attempt to provide a more cohesive view of the subject with the following hypotheses: (1) the paradigmatic examples of deductions, such as modus ponens and hypothetical syllogism, are not inferential forms, but coherence requirements for inferences; (2) since any reasoner aims to be coherent, any inference (...) must be deductive; (3) a coherent inference is an intuitive process where the premises should be taken as sufficient evidence for the conclusion, which on its turn should be viewed as necessary evidence for the premises in some modal range; (4) inductions, properly understood, are abductions, but there are no abductions beyond the fact that in any inference the conclusion should be regarded as necessary evidence for the premises; (5) monotonicity is not only compatible with the retraction of past inferences given new information, but it is a requirement for it; (6) this explanation of inferences holds true for discovery processes, predictions and trivial inferences.

In metasemantics, semantic dispositionalism is the view that what makes it the case that, given the value of the relevant parameters, a certain linguistic expression refers to what it does are the speakers’ dispositions. In the literature, there is something like a consensus that the fate of dispositionalism hinges on the status of three arguments, first put forward by Saul Kripke ‒ or at least usually ascribed to him. This paper discusses a different, and strangely neglected, anti-dispositionalist argument, which develops (...) some remarks first put forward by Paul Boghossian and Anandi Hattiangadi and revolves around the idea that semantic dispositionalists have no way to justify their privileging certain dispositions, the ones they take to be reference-determining, over all the others. After some background (Section 1) and a first presentation of the argument (Section 2), I discuss three ways a dispositionalist might try to answer it and find them all wanting (Section 3). (shrink)

P.F. Strawson contributed to many philosophical domains, including the philosophy of language, the history of philosophy, metaphysics, moral philosophy and philosophical methodology. Most of his contributions in these areas have influenced contemporary debates, either because his views are still defended or because they are still considered worthy of detailed responses. His views on the philosophy of logic have been only rarely discussed, however. My aim in this paper is threefold. First, I provide a systematic account of Strawson’s philosophy of logic. (...) I argue that Strawson is an important predecessor of logical expressivism, a contemporary position in the philosophy of logic most notably defended by Robert Brandom. My main focus is on Strawson’s largely-neglected 1982 paper ‘Logical Form and Logical Constants’, which contains his most mature ideas on the topic. Second, while Strawson’s position is of historical and independent philosophical interest, I argue that he leaves many points unclear. Finally, I propose several clarifications of Strawson’s position. (shrink)

In this work we argue that there is no strong demarcation between pure and applied mathematics. We show this first by stressing non-deductive components within pure mathematics, like axiomatization and theory-building in general. We also stress the “purer” components of applied mathematics, like the theory of the models that are concerned with practical purposes. We further show that some mathematical theories can be viewed through either a pure or applied lens. These different lenses are tied to different communities, which endorse (...) different evaluative standards for theories. We evaluate the distinction between pure and applied mathematics from a late Wittgensteinian perspective. We note that the classical exegesis of the later Wittgenstein’s philosophy of mathematics, due to Maddy, leads to a clear-cut but misguided demarcation. We then turn our attention to a more niche interpretation of Wittgenstein by Dawson, which captures aspects of the aforementioned distinction more accurately. Building on this newer, maverick interpretation of the later Wittgenstein’s philosophy of mathematics, and endorsing an extended notion of meaning as use which includes social, mundane uses, we elaborate a fuzzy, but more realistic, demarcation. This demarcation, relying on family resemblance, is based on how direct and intended technical applications are, the kind of evaluative standards featured, and the range of rhetorical purposes at stake.

What is the relation of logic to thinking? My dissertation offers a new argument for the claim that logic is constitutive of thinking in the following sense: representational activity counts as thinking only if it manifests sensitivity to logical rules. In short, thinking has to be minimally logical. An account of thinking has to allow for our freedom to question or revise our commitments – even seemingly obvious conceptual connections – without loss of understanding. This freedom, I argue, requires that (...) thinkers have general abilities to respond to support and tension among their thoughts. And these abilities are constituted by following logical rules. So thinkers have to follow logical rules. But there isn’t just one correct logic for thinking. I show that my view is consistent with logical pluralism: there are a range of correct logics, any one of which a thinker might follow. A logic for thinking does, however, have to contain certain minimal principles: Modus Ponens and Non-Contradiction, and perhaps others. We follow logical rules by exercising logical capacities, which display a distinctive first-person/third-person asymmetry: a subject can find the instances of a rule compelling without seeing them as instances of a rule. As a result, there are two limits on illogical thinking. First, thinkers have to tend to find instances of logical rules compelling. Second, thinkers can’t think in obviously illogical ways. So thinking has to be logical – but not perfectly so. When we try to think, but fail, we produce nonsense. But our failures to think are often subjectively indistinguishable from thinking. To explain how this occurs, I offer an account of nonsense. To be under the illusion that some nonsense makes sense is to enter a pretence that the nonsense is meaningful. Our use of nonsense within the pretence relies on the role of logical form in understanding. Finally, while the normativity of logic doesn’t fall directly out of logical constitutivism, it’s possible to build an attractive account of logical normativity which has logical constitutivism as an integral part. I argue that thinking is necessary for human flourishing, and that this is the source of logical normativity. (shrink)

This three-part chapter explores a higher-order logic we call ‘Classicism’, which extends a minimal classical higher-order logic with further axioms which guarantee that provable coextensiveness is sufficient for identity. The first part presents several different ways of axiomatizing this theory and makes the case for its naturalness. The second part discusses two kinds of extensions of Classicism: some which take the view in the direction of coarseness of grain (whose endpoint is the maximally coarse-grained view that coextensiveness is sufficient for (...) identity), and some which take the view in the direction of fineness of grain (whose endpoint is the maximally fine-grained theory containing all distinctness claims compatible with Classicism). The third part introduces some techniques for constructing models of Classicism, and uses them to prove the consistency of many of the extensions of Classicism introduced in the second part.

It is my intention in this article to present some consequences of Quine’s thesis on the dependence of ontology on ideology (Quine, 1980), seeking an argument for my own thesis on the dependence (theoretical) existence of entities on identity type or ontology dependence on logic and language.If Quine's thesis is correct, then we can expand the resolution of this conclusion and say that ontology depends on the identity or on identification of the "identity criteria for conceptual schemes" (Davidson, 2001) which (...) is constructed in the theory. Consequently I will speak about types of identity which adapts choice of ontology and of which depends ontology of a theory. Here I want to connect the different types of use of the term identity in Aristotle's writings and the different types of predications that are based on them with the concept of identity as the equivalence of symbols in modern logic. I want to reinterpret Quine's statement: "There is no entity without identity " in the form of imlication "What (kind of) identity such (kind of ) entity." . (shrink)

In the article we consider the relationship of traditional provisions of basic logical concepts and confront them with new and modern approaches to the same concepts. Logic is characterized in different ways when it is associated with syllogistics (referential – semantical model of logic) or with symbolic logic (inferential – syntactical model of logic). This is not only a difference in the logical calculation of (1) concepts, (2) statements, and (3) predicates, but this difference also appears in the treatment of (...) the calculative abilities of logical forms, the ontological-referential status of conceptual content and the inferential-categorical status of logical forms. The basic markers or basic ideas that separate ontologically oriented logic from categorically oriented logic are the (1) concept of truth, the (2) concept of meaning, the (3) concept of identity, and the (4) concept of predication. Here, this differences are explicitly demonstrated by the introduction of differential terminology. From this differential methodology follows a new set of characterizations of logic. (shrink)

An introduction to philosophy of language since Frege, focusing on the 20th century.

The book is about logical analysis of natural language. Since we humans communicate by means of natural language, we need a tool that helps us to understand in a precise manner how the logical and formal mechanisms of natural language work. Moreover, in the age of computers, we need to communicate both with and through computers as well. Transparent Intensional Logic is a tool that is helpful in making our communication and reasoning smooth and precise. It deals with all kinds (...) of linguistic context in a fully compositional and anti-contextual way. (shrink)

I propose that an irreducible property of physical space — consistency — is the origin of logic. I propose that an inconsistent space is inconceivable and that this inconceivability can be recognized as the force behind logical propositions. The implications of this argument are briefly explored and then applied to address two paradoxes: Zeno of Elea’s paradox regarding the race between Achilles and the Tortoise, and Lewis Carroll’s paradox regarding the Tortoise’s conversation with Achilles after the race. I conclude that (...) Achilles would have won on both accounts, in the race and the argument, by invoking the consistency of space as the foundation of both movement across space and logical argument. (shrink)

Can we do science without numbers? How much contingency is there? These seemingly unrelated questions--one in the philosophy of math and science and the other in metaphysics--share an unexpectedly close connection. For as it turns out, a radical answer to the second leads to a breakthrough on the first. The radical answer is new view about modality called compossible immutabilism. The breakthrough is a new strategy for doing science without numbers. One of the chief benefits of the new strategy is (...) that, unlike the existing substantialism approach from Field (1980), the new strategy naturally generalizes to theories formulated in terms of state space.

There are many different ways to talk about the world. Some ways of talking are more expressive than others—that is, they enable us to say more things about the world. But what exactly does this mean? When is one language able to express more about the world than another? In my dissertation, I systematically investigate different ways of answering this question and develop a formal theory of expressive power, translation, and notational variance. In doing so, I show how these investigations (...) help to clarify the role that expressive power plays within debates in metaphysics, logic, and the philosophy of language. (shrink)

When it comes to questions about alternative visions for philosophical engagement, Heidegger’s work makes for an interesting case study, especially if we focus on his texts from the turbulent 1930s. As a shortcut into this contested territory, it is instructive to examine Heidegger’s anti-journalistic gestures, centered on the question whether this animosity is bound to drive a wedge between, or rather prompt a re-approximation of, philosophy and public scholarship. To render this programmatic concern more specific, the present essay aims to (...) reassess Heidegger’s profile by considering his account of language as the “most dangerous of goods” bestowed on humans. This theme can serve as an expedient starting point for scrutinizing philosophers’ self-understanding as daring explorers in pursuit of profound insights into the human condition, and their ability to balance excitement and sobriety.

We often read Plato’s cave allegory for its trajectory: out of darkness into light. The back of the cave—where imagination projects fantasies onto shadows—is a place to flee. This part of the allegory reduces reality testing to thought or imagining, ignoring action and the people or things engaged. Yet thinkers prominent in our time—Immanuel Kant and W. V. O. Quine—suppose that our experience of the world is that of the cave’s prisoners: we too mistake fantasies for reality. This is an (...) odd stance when practical life and science—beliefs informed by action and experiment—are better tests of reality than their arguments for world‐making. (shrink)
