Ludwig Wittgenstein

τὰ ὄντα ἰέναι τε πάντα καὶ μένειν οὐδέν: Another look at being, asking what a interlocutor means to show by saying they feel themselves to be something. An ambiguity of the verb "to be" is disambiguated to reveal that it can be meant to show what something is and a process of being something. The relationship between being and essence is made by describing engagement through the encounter, giving us a non-exhaustive account of something's essence. Practice is then understood as (...) a process within a social context where humans form the senses in which one can be, with their possibilities informed by encounters with what is substantive of those senses. The resulting implications with regards to authenticity, social belonging, and anthropology are briefly discussed. (shrink)

The philosopher and builder Ludwig Wittgenstein remarks that architecture is more difficult than philosophy. He suggests an exhaustion criterion for how difficult a discipline is: a field is more difficult the more exhausting it is. I make a case against this claim. There was once a demand to prevent the Greek myths from establishing themselves in the curriculum by means of “our own rival myths.” It is difficult to compete with a renowned Greek myth, but if one does produce a (...) rival, it may well not be exhausting to do so.

This paper considers the debate between teams of skilled contributors versus a genius by focusing on a specific case: a team project to overturn some remarks by Wittgenstein on Frazer’s The Golden Bough. In theory, there can be a team which does this, but in actual practice, such a team seems unlikely to arise.

We propose the concepts of philomatics and psychomatics as hybrid combinations of philosophy and psychology with mathematics. We explain four motivations for this combination which are fulfilling the desire of analytical philosophy, proposing science of philosophy, justifying mathematical algorithms by philosophy, and abstraction in both philosophy and mathematics. We enumerate various examples for philomatics and psychomatics, some of which are explained in more depth. The first example is the analysis of relation between the context principle, semantic holism, and the usage (...) theory of meaning with the attention mechanism in mathematics. The other example is on the relations of Plato's theory of forms in philosophy with the holographic principle in string theory, object-oriented programming, and machine learning. Finally, the relation between Wittgenstein's family resemblance and clustering in mathematics is explained. This paper opens the door of research for combining philosophy and psychology with mathematics. (shrink)

Coping with everyday life limits the extent of one’s scepticism. It is practically impossible to doubt the existence of the things with which one is immediately engaged and interacting. To doubt that, say, a door exists, is to step back from merely using the door (opening it) and to reflect on it in a detached, theoretical way. It is impossible to simultaneously act and live immersed in situation S while doubting that one is in S. Sceptical doubts—such as ‘Is this (...) really a door?’, ‘Am I really walking?’ — require a reflective withdrawal in thought from the situation at hand. Maintaining sceptical doubt while coping with everyday life requires a split consciousness, a bad faith, with one part of consciousness doubting the existing of things that the other part takes forgranted. For this reason, a sustained lived sceptical doubt is sometimes thought to be impossible. -/- In this article, I examine Wittgenstein's response to scepticism in "On Certainty". I argue that one of his responses is "the response based on action", which is (as other Wittgenstein interpreters have noted) a characteristically pragmatist response. I then evaluate the quality of this pragmatist response to scepticism, noting that actions just as much as representations are susceptible to mis-interpretation. It is argued that despite the insights contained in it, Wittgenstein's contextualism about meaning is inadequate to rescue the Wittgensteinian response to scepticism. (shrink)

In Zettel, Wittgenstein considered a modified version of Cantor’s diagonal argument. According to Wittgenstein, Cantor’s number, different with other numbers, is defined based on a countable set. If Cantor’s number belongs to the countable set, the definition of Cantor’s number become incomplete. Therefore, Cantor’s number is not a number at all in this context. We can see some examples in the form of recursive functions. The definition "f(a)=f(a)" can not decide anything about the value of f(a). The definiton is incomplete. (...) The definition of "f(a)=1+f(a)" can not decide anything about the value of f(a) too. The definiton is incomplete.<br><br>According to Wittgenstein, the contradiction, in Cantor's proof, originates from the hidden presumption that the definition of Cantor’s number is complete. The contradiction shows that the definition of Cantor’s number is incomplete. <br><br>According to Wittgenstein’s analysis, Cantor’s diagonal argument is invalid. But different with Intuitionistic analysis, Wittgenstein did not reject other parts of classical mathematics. Wittgenstein did not reject definitions using self-reference, but showed that this kind of definitions is incomplete.<br><br>Based on Thomson’s diagonal lemma, there is a close relation between a majority of paradoxes and Cantor’s diagonal argument. Therefore, Wittgenstein’s analysis on Cantor’s diagonal argument can be applied to provide a unified solution to paradoxes. (shrink)

Ludwig Wittgenstein has often been called a quietist. His work has inspired a rich and varied array of theories in moral philosophy. Some prominent meta-ethicists have also been called quietists, or ‘relaxed’ as opposed to ‘robust’ realists, sometimes with explicit reference to Wittgenstein in attempts to clarify their views. In this chapter, I compare and contrast these groups of theories and draw out their importance for contemporary meta-ethical debate. They represent countercultures to contemporary meta-ethics. That is, they reject in different (...) ways one or more of the common assumptions that, whilst not universally shared, shape how to understand and engage in contemporary meta-ethical debate. Despite striking similarities, I argue that the ‘quietist’ label has obscured the views it is used to describe, the crucial differences between them, and the challenge that they offer to the predominant culture of meta-ethical enquiry. That challenge is this: there are plausible different ways of understanding and doing meta-ethics to those of the meta-ethical orthodoxy. We ignore such heterodoxy at our own peril. (shrink)

A retelling of Plato's famous cave allegory. Inspired by Dōgen, Nietzsche, and Wittgenstein.

With respect to the metaphysics of infinity, the tendency of standard debates is to either endorse or to deny the reality of ‘the infinite’. But how should we understand the notion of ‘reality’ employed in stating these options? Wittgenstein’s critical strategy shows that the notion is grounded in a confusion: talk of infinity naturally takes hold of one’s imagination due to the sway of verbal pictures and analogies suggested by our words. This is the source of various philosophical pictures that (...) in turn give rise to the standard metaphysical debates: that the mathematics of infinity corresponds to a special realm of infinite objects, that the infinite is profoundly huge or vast, or that the ability to think about infinity reveals mysterious powers in human beings. First, I explain Wittgenstein’s general strategy for undermining philosophical pictures of ‘the infinite’ – as he describes it in Zettel; and then show how that critical strategy is applied to Cantor’s diagonalization proof in Remarks on the Foundations of Mathematics II.

There is no single Jewish philosophical conception of God, and the array of competing conceptions does not lend itself to easy systemization. Nonetheless, it is the aim of this chapter to provide an overview of this unruly theological terrain. It does this by setting out ‘maps’ of the range of positions which Jewish philosophers have taken regarding key aspects of the God-idea. These conceptual maps will cover: (i) how Jewish philosophers have thought of the role and status of conceiving of (...) God in the first place; (ii) what Jewish philosophers have understood to be definitive of God or Divinity; (iii) Jewish philosophical conceptions of God’s oneness; (iv) Jewish philosophical conceptions of God’s transcendence or immanence; (v) Jewish philosophical conceptions of God’s personhood or lack thereof; (vi) Jewish philosophical understandings of why God created (or caused) a world; and (vii) Jewish philosophical understandings of God’s relationship to the Jewish people. Jointly, these seven conceptual maps outline the broad range of vying conceptions of God that have been held by Jewish philosophers over the centuries, while also enabling the reader a bird’s-eye-view of how these multiple conceptions relate to one another. The chapter concludes by touching on what Jewish philosophers have made of this immense diversity of theological conceptions included within the tradition. (shrink)

This paper presents an account of Iris Murdoch's engagement with the work of Martin Heidegger. It covers her early discussions and evaluations of him in The Sovereignty of Good, through to her late Heidegger manuscript, covering both his early and late work. It details the significant changes that occur in her evaluation of him, as well as the key sympathies identified and criticisms developed in the late manuscript. The focus is on her insistence that only 'the Good', and not Heidegger's (...) 'Being', can fill the space left by the traditional Western God, and of the related failure in Heidegger to account properly for value. (shrink)

This paper continues my development of philosophy of religion as multi-disciplinary comparative research. An earlier paper, “Wittgenstein and Contemporary Belief-Credence Dualism” compared Wittgensteinian reflections on religious discourse and praxis with B-C dualism as articulated by its leading proponents. While some strong commonalities were elaborated that might help to bridge Continental and Analytic approaches in philosophy of religion, Wittgenstein was found to be a corrective to B-C dualism especially as regards how the psychology and philosophy of epistemic luck/risk applies to doxastic (...) faith ventures. This paper aims to further elaborate a basis for improved dialogue between philosophers, theologians, and scholars in special sciences which study religion. I call this basis the Triangulated model the ABC’s of religious epistemics in order to contrast it with the B-C dualist proposal. (shrink)

In this paper, I will argue against certain criticisms of Kripke’s Wittgenstein’s sceptical argument and sceptical solution, made especially by Baker and Hacker, McGinn, and McDowell. I will show that their interpretation of Kripke’s Wittgenstein’s view is misplaced. According to Kripke’s Wittgenstein’s sceptical argument, there is no fact as to what someone means by her words. For Kripke, this conclusion, combined with Classical Realist view of meaning, leads to the Wittgensteinian paradox, according to which there is no such thing as (...) meaning anything by any word. Wittgenstein presents this paradox in paragraph 201 of the Philosophical Investigations. As Kripke reads Wittgenstein, Wittgenstein is in agreement with his sceptic on the sceptical conclusion of the sceptical argument, that is, that there is no fact about meaning, and builds his sceptical solution on an endorsement of that. McDowell, McGinn, and others have objected that Kripke has failed to properly understand Wittgenstein’s main remarks in 201, that is, that the paradox is the result of a misunderstanding of the ordinary notion of meaning. Wittgenstein does not accept such a sceptical conclusion. I will use the distinction George Wilson draws between two different conclusions of the sceptical argument and show that Kripke has respected all of the remarks that Wittgenstein has put in section 201. (shrink)

Kripke in his famous book on Wittgenstein’s later philosophy argues, on behalf of Wittgenstein, that there can be no fact of the matter as to what a speaker means by her words, that is, no fact that can meet the Constitution Demand and the Normativity Demand. He particularly argues against the dispositional view, according to which meaning facts are constituted by facts about the speaker's dispositions to respond in a certain way on certain occasions. He argues that facts about dispositions (...) are finite and are incapable of constituting facts about what speakers mean by their words; they are also essentially descriptive, not prescriptive and thus, cannot meet the Normativity Demand. Hannah Ginsborg, one of the most important contemporary philosophers of language, has recently attempted to resist Kripke’s Wittgenstein’s arguments against by defending a new sort of reductive dispositionalism which can meet both demands at the same time. In this paper, I will argue that she would not be successful in her project. (shrink)

En este capítulo, analizo a qué se refiere Kuhn cuando habla de metáfora en las Conferencias Notre Dame, pero sobre todo a explorar a qué no se refiere. En la primera sección, analizo por qué Kuhn usa el término “metáfora” para referirse al proceso de aprendizaje de lenguaje científico, en particular, los paralelismos que encuentra entre ambos fenómenos. En la segunda sección, se presentan algunos aspectos centrales de dos teorías influyentes sobre la metáfora: la teoría del mapeo estructural y la (...) teoría de las metáforas conceptuales. Luego, en la sección III, vuelvo a Kuhn para ver las diferencias cruciales que encontramos entre los procesos metafóricos y el proceso de ostensión del que habla el autor. Finalmente, presento una noción del segundo Wittgenstein, la idea de figura, para ofrecer una nueva forma de interpretar la idea de que el cambio revolucionario involucra un cambio en la metáfora central.

This chapter looks for “continuity and convergence” between Davidson’s and Wittgenstein’s work, identifies common themes and family resemblances, as well as disagreements, especially in the theory of meaning. I take up in turn: -/- (1) their shared rejection of the utility of an ontology of meanings; (2) a convergence on the idea that we must show rather than say what an expression means; (3) the similarities and differences between them on meaning as use and the sense in which rule following (...) is essential for meaning; (4) the publicity of language, first in connection with radical interpretation; and (5) then with Davidson’s later work on triangulation in securing objective thought.

This is a review of a volume comprising 18 of Eckart Förster’s most important essays, written between 1987 and 2022, all of which touch upon the theme of limits of cognition. Among the issues tackled are Kant’s Opus Postumum, Goethe’s project of a scientia intuitiva or science of the intuitive understanding, the significance of §§76–77 of the third Critique for post-Kantianism, the case for Hölderlin’s authorship of the Oldest System-Programme of German Idealism, and Hegel’s early ideas on logic and phenomenology. (...) My discussion of the volume focuses on three aspects. (i) I give a brief outline of its structure and goals; (ii) I investigate some of its highlights and central themes; and (iii) I place Förster’s picture of Kant and post-Kantianism within current scholarship and confront it with an alternative interpretive option: a reading of Kant as concerned with non-contrastive limits of cognition and intelligibility.

In the Tractatus, Wittgenstein conceives of tautology as 'saying nothing'. More precisely, he holds -- or so this essay contends -- that it says nothing in virtue of possessing a zero quantity of sense. Insofar as it is the limit of a series of propositions of diminishing quantity of sense, tautology resembles a degenerate conic section. But it also resembles the result of a summing together of equal and opposite linear vector quantities. Both of these models shape Wittgenstein's conception of (...) tautology in the Tractatus, though they are not fully reconciled. Many of the puzzling features of the Tractatus's view of logic arise from this failure to affect the needed reconciliation. These points are argued for by working through the development of Wittgenstein's views on these matters in the Wartime Notebooks and other pre-Tractatus writings. (shrink)

This chapter argues that several aspects of Bernard Williams’s style, methodology, and metaphilosophy can be read as evolving dialectically out of Wittgenstein’s own. After considering Wittgenstein as a stylistic influence on Williams, especially as regards ideals of clarity, precision, and depth, Williams’s methodological debt to Wittgenstein is examined, in particular his anthropological interest in thick concepts and their point. The chapter then turns to Williams’s explicit association, in the 1990s, with a certain form of Wittgensteinianism, which he called ‘Left Wittgensteinianism’. (...) It is shown how this is not a sudden conversion, but the direct product of Williams’s longstanding critical engagement with Wittgenstein’s methodology and metaphilosophy: Williams arrives at this position by envisaging a Wittgensteinianism that thinks in concrete sociohistorical terms, embraces genuine explanation, and relinquishes its insistence on the purity of philosophy. When properly understood, moreover, this critique turns out to be continuous with Williams’s advocacy of a conception of philosophy as a humanistic discipline. Finally, it is shown that Williams inherits from Wittgenstein a certain understanding of how philosophy can help us to live, in particular the therapeutic ambition to liberate us from distortions in our self-understanding by assembling reminders.

Bernard Williams argued that historical and philosophical inquiry were importantly linked in a number of ways. This introductory chapter distinguishes four different connections he identified between philosophy and history. (1) He believed that philosophy could not ignore its own history in the way that science can. (2) He thought that when engaging with philosophy’s history primarily to produce history, one still had to draw on philosophy. (3) Even doing history of philosophy philosophically, i.e. primarily to produce philosophy, required a keen (...) sense of how historically distant from us past philosophers were, on his view, because the point of reading them was to confront something different from the present. (4) He held that systematic philosophy itself needed to be done historically, engaging not necessarily with its own history, but with that of the concepts it sought to understand. The chapter closes with an overview of the volume’s structure and content. (shrink)

James Shaw has written an excellent book on Wittgenstein’s rule-following considerations. It manages to provide fresh perspectives on a topic on which it seemed.

One of the important ethical concepts that has occupied the minds of many philosophers in the past years is the concept of "moral certainty". This means whether there are moral propositions that are so certain that no doubt or argument or evidence can face them. According to some philosophers, for example, the statement "the wrongness of killing innocent people" brings us such moral certainty. Among the philosophers who have written in this field, two basic readings of Nigel Pleasants and Michael (...) Kober can be mentioned. Pleasant considers moral certainty to be an absolute and natural concept that is the basis of our moral judgments, and on the other hand, Kober considers moral certainty to be a relative concept and believes that our certainties are rooted in linguistic society, culture and time. In this article, we try to address the different dimensions of the concept of "moral certainty" and the importance of its application in two different and important readings. (shrink)

This paper defends a reading of Wittgenstein’s philosophy of mathematics in the Lectures on the Foundation of Mathematics as a radical conventionalist one, whereby our agreement about the particular case is constitutive of our mathematical practice and ‘the logical necessity of any statement is a direct expression of a convention’ (Dummett 1959, p. 329). -/- On this view, mathematical truths are conceptual truths and our practices determine directly for each mathematical proposition individually whether it is true or false. Mathematical truths (...) are thus not consequences of a prior adoption of a convention or rules as orthodox conventionalism has it. -/- The goal of the paper is not merely exegetical, however, and argues that radical conventionalism can withstand some of the most difficult objections that have been brought forward against it, including those of Dummett himself, and thus that radical conventionalism has been prematurely excluded from consideration by philosophers of mathematics.

Despite overlooking religious topics, Wittgenstein’s Philosophical Investigations (PI) has had a large impact in philosophy of religion. This article surveys that influence and the reasons for it. In what follows, I first describe the reception of certain key concepts from the PI in philosophy of religion. Second, I examine a few scattered remarks on religious topics in the PI. Third, I consider the relevance of the PI for contemporary philosophy of religion. I argue that the dialogical nature of the PI, (...) allowing different generations of readers to engage it with their particular philosophical problems, is key to its longterm influence. (shrink)

This chapter serves as an opinionated introduction to the problem of convergence (that there is no clear convergence to the truth in philosophy) and the problem of peer disagreement (that disagreement with a peer rationally demands suspending one’s beliefs), and some of the issues they give rise to, namely, philosophical skepticism and progress in philosophy. After introducing both topics and surveying the various positions in the literature we explore the prospects of an alternative, hinge-theoretic account.

In this paper, we tackle the widely held view that practice-oriented approaches to ethics are conservative, preserving the moral status quo, and, in particular, that they do not promote any (fundamental) change in our dealings with animals or formulate clear principles that help us to achieve such change. We shall challenge this view with reference to Wittgensteinian ethics. As a first step, we show that moral thought and action rest on basic moral certainties like: equals are to be treated equally (...) and unequals unequally. We then explore the relations between this insight and the notion of the difficulty of reality elaborated by Cora Diamond. Our goal is to show that a Wittgensteinian-Diamondian approach to animal ethics is not necessarily morally conservative. Indeed, it offers a profound practice-oriented approach to animal ethics that is capable of promoting change in human dealings with animals because it is compatible with radical critique. (shrink)

n this paper, we identify and explain three kinds of bedrock in moral thought. The term "bedrock," as introduced by Wittgenstein in §217 of the Philosophical Investigations, stands for the end of a chain of reasoning. We affirm that some chains of moral reasoning do indeed end with certainty. However, different kinds of certainties in morality work in different ways. In the course of systematizing the different types of certainties, we argue that present accounts of certainties in morality do not (...) reflect their diversity. Our analysis yields three types of moral certainty: QUASI-UNDOUBTABLE CERTAIN PROPOSITIONS, CERTAIN PROPOSITIONS, and TRANSCENDENTAL CERTAINTIES. We show that the first two types can, at least to some extent, be intelligibly doubted. Therefore, they do not possess the characteristics that would classify them as bedrock in the strictest sense. TRANSCENDENTAL CERTAINTIES cannot likewise be doubted because they are rules that enable moral thinking. Thus, deviating from them is unintelligible. We shall argue that all three types reflect ways in which moral language games come to an end, while only one, TRANSCENDENTAL CERTAINTIES, displays the characteristic of being solid bedrock.

To Wittgenstein’s late thought is often attributed a form of cultural or epistemic relativism, according to which truths are relative to the criteria of justification valid within a linguistic community. This paper aims to show that this attribution lies largely on a misinterpretation of Wittgenstein’s ideas on the relation between language-games and forms of life. In the first section are presented the grounds for some relativist readings of Wittgenstein’s thought. In the second section, through the analysis of some passages of (...) the Tractatus and On Certainty, it is argued that, although Wittgenstein insisted on the “ungroundedness” of our language-games, he did not mean that any epistemic attitude, as long as it is endorsed by a community, is as valid as any other one. Rather, it is possible to show that some games better apply to our world and appear thus as more objective, so that there can be a difference in the validity of world-picures, contrary to what the epistemic relativist holds. In the third and final section, it is claimed that the different communities that appear in Wittgenstein’s examples are not actual or existing alternative possibilities, but an imaginary anthropology that Wittgenstein uses to enlighten how we, humans, work with our language-games. So, it is not possible to attribute him the idea that different games underly different forms of life, as some relativist authors do. It is concluded that Wittgenstein was not likely to be a cultural relativist. (shrink)

This paper explores Thomas Kuhn’s mature conception of incommensurable theories as collective structured lexicons that are not mutually translatable. As will be argued, his view on this issue can profitably be approached in the light of the broad pragmatist attitude that one finds at the core of Wittgenstein’s late philosophy of language, which can also consistently be ascribed to Kuhn.

In this Element, the author set out to answer a twofold question concerning the importance of music to Wittgenstein's philosophical progression and the otherness of this sort of philosophical importance vis-à-vis philosophy of music as practiced today in the analytic tradition. The author starts with the idea of making music together and with Wittgenstein's master simile of language-as-music. The author traces these themes as they play out in Wittgenstein early, middle, and later periods. The author argues that Wittgenstein's overarching reorientation (...) of the concept of depth pertaining to music in the aftermath of his anthropological turn, and against the backdrop of the outlook of German Romanticism, culminates in his unique view of musical profundity 'knowledge of people'. This sets Wittgenstein's view in sharp contrast with certain convictions and debates that typify current analytically bent philosophy of music. (shrink)

In his lecture “Philosophy and the Unheard,” Cavell invites us to observe a pervasive analogy between Schoenberg’s idea of the twelve-tone row and Wittgenstein’s idea of grammar, which is supposed to encapsulate an expansive, sweeping philosophical program—Cavell’s own. For Cavell, the analogy evinces not only the kind of reading of Wittgenstein’s Philosophical Investigation, which is attuned to Wittgenstein’s seemingly paradoxical amalgamation of embrace and resistance in regarding to the conditions of modernity, but also a kind of philosophy of music, which (...) is illuminated by musical procedure. In this essay I probe into Cavell’s analogy, which, I contend, rests on Cavell’s interpretation (contra Von Wright) of Spengler’s influence on Wittgenstein. I argue that Cavell delineated the analogy in a way which does not consider a deeply felt gradation in Wittgenstein’s philosophical attitude toward modern music. This ultimately renders Schoenberg’s composition with twelve-tone incommensurate with Wittgenstein’s Spenglerian scheme of musical decline. I also argue that “Schoenbergian unheard” is not analogous to its purported Wittgensteinian counterpart. While the former inheres in comprehensibility—namely, correct, conscious application of the kind of contrived rules that would ensure coherence—the latter inheres in transparency, namely, a familiar physiognomy, which is internally related to the preconditions as well as the lived, embodied realities of musical intelligibility. From Wittgenstein’s perspective, the Schoenbergian idea of the row with its unforeseen yet pervasive consequences turns out to be tantamount to an idea of grammar for music for the meaning-blind. I conclude that in this “tale of two unheards,” Cavell invariably remains on the side of Wittgenstein. Philosophy, as it mattered most to him, has no business with music for the meaning-blind. (shrink)

This essay explores Wittgenstein’s encounter with Stumpf’s work in Tone Psychology during a rarely studied period in Wittgenstein’s early career when he worked as a researcher in Myers’s laboratory for experimental psychology in Cambridge. I argue that Stumpf’s emphasis on the notion of musicality as the ability to characterize what is ‘musical’ about music troubled Wittgenstein’s initial formulation of his career-long adherence to the comparison between language and music. In the Tractatus the importance of internal projective relations far exceeds that (...) of arbitrariness in language. This results in the curious elision of musicality in the Tractatus, as shown in his gramophone analogy. The acknowledgment of the enormous complexity pertaining to the facts of human life remained underdeveloped in Wittgenstein’s philosophy until the anthropological turn in his middle-period. Only then do we see the blooming of the language-as-music simile and its eventual impact on Wittgenstein’s later philosophy. (shrink)

The clean separation between manifold phenomena and a systematic order that prevails in them is a basic feature of the rational-scientific orientation system. The first authoritative formulation of this premise is found in Plato. His discussion of constitutive forms of world events has initiated a broad development in the history of philosophy, which is also effective today in the preference for reason-guided analyses of often confusing circumstances. The authors of this volume address the lasting relevance of this idea within two (...) interrelated areas of research, namely Plato scholarship and contemporary Platonism. Of particular interest is the relationship between Plato and Wittgenstein. Following this overall idea, this volume is divided into three sections: Plato scholarship, Platonism, and Plato and Wittgenstein. As the contributions show, Platonism proves to be not only a purely historical-exegetical field of research but rather a fruitful stimulus for contemporary discussions on logical, linguistic, and social topics.

In his Wittgenstein on Rules and Private Language, Saul Kripke famously raised two sorts of problems for responses to the meaning skeptic that appealed to how we were disposed to use our words in the past. The first related to the fact that our “dispositions extend to only finitely many cases” while the second related to the fact that most of us have “dispositions to make mistakes.” The second of these problems has produced an enormous, and still growing, literature on (...) the purported ‘normativity’ of meaning, but the first has received (at least comparatively) little attention. It will be argued here, however, that (1) the fact that we can be disposed to make mistakes doesn’t present a serious problem for many disposition-based responses to the skeptic, and (2) considerations of the ‘finiteness’ of our dispositions point, on their own, to an important way that the relation between meaning and use must be understood as ‘normative’. In particular, the assumption that words have determinate meanings, more so than the assumption that they have ‘correctness’ conditions, rules out the possibility of understanding the relation between meaning and use in the more descriptive fashion commonly associated with dispositionalism. Nevertheless, if the relation of meaning and use is understood in a more normative key, responding to the meaning-skeptic with facts about one’s dispositions will turn out to be perfectly legitimate, though it will prevent one from being the sort of ‘dispositionalist’ that Kripke gives, without any real argument, a monopoly on disposition-based responses.

Is it sensical to ascribe psychological predicates to AI systems like chatbots based on large language models (LLMs)? People have intuitively started ascribing emotions or consciousness to social AI (‘affective artificial agents’), with consequences that range from love to suicide. The philosophical question of whether such ascriptions are warranted is thus very relevant. This paper advances the argument that LLMs instantiate language users in Ludwig Wittgenstein’s sense but that ascribing psychological predicates to these systems remains a functionalist temptation. Social AIs (...) are not full-blown language users, but rather more like Italo Calvino’s literature machines. The ideas of LLMs as Wittgensteinian language users and Calvino’s literature-producing writing machine are combined. This sheds light on the misguided functionalist temptation inherent in moving from equating the two to the ascription of psychological predicates to social AI. Finally, the framework of mortal computation is used to show that social AIs lack the basic autopoiesis needed for narrative façons de parler and their role in the sensemaking of human (inter)action. Such psychological predicate ascriptions could make sense: the transition ‘from quantity to quality’ can take place, but its route lies somewhere between life and death, not between affective artifacts and emotion approximation by literature machines.

In this thesis, I compare Kant and Wittgenstein’s critical philosophies with respect to Transcendental Idealism, as a doctrine meant to “prove” the possibility of Metaphysics. My Central Question is: Is the early Wittgenstein a transcendental idealist? In virtue of a distinction between Transcendentalism and Transcendental Idealism, I answer “No”, by arguing that the early Wittgenstein is a transcendental philosopher, but not a transcendental idealist of any kind. In particular, I distinguish two variants of Transcendental Idealism, namely an effable variant, which (...) Kant endorsed, and an ineffable variant, often ascribed to Wittgenstein. And I argue that Wittgenstein cannot commit to either variant. This raises questions as to what kind of transcendental philosopher Wittgenstein is, if not an idealist one, and how his stance may bear on Metaphysics. I answer both questions by the end of the work. -/- The dissertation’s core is structured into two parallel Parts, one on Kant (PartK) and one on Wittgenstein (PartW). Each Part is composed of 3 Chapters. In PartK, I give a general account of -/- (1K) Transcendental Philosophy—based on Kant’s one, but less restrictive than his; (2K) Effable Transcendental Idealism—by expounding Kant’s doctrine; (3K) Ineffable Transcendental Idealism—inspired by Kant, but not strictly Kantian. -/- In PartW, I argue that -/- (1W) the early Wittgenstein is a transcendental philosopher; (2W) the early Wittgenstein is not an effable transcendental idealist; (3W) the early Wittgenstein is not an ineffable transcendental idealist. -/- By the final Chapter of the work, I argue that -/- (7) the early Wittgenstein is a transcendental quietest, -/- namely, someone who accepts that there are transcendental conditions of cognition, while refraining from commitment over their metaphysical nature and status. However, Wittgenstein’s (ineffable) version of Transcendental Quietism is extreme, as it turns the whole of Metaphysics into mere nonsense. I will thus conclude the work by sketching a moderate (effable) version, whereby Transcendental Metaphysics is possible, but while we should engage with it, we should not engage in it. (shrink)

[Winner of the Teorema Essay Prize for Young Scholars 2024]. How can we know we are not dreaming? In this essay, I tackle this and related questions from a transcendental standpoint, by building a philosophical narrative centred upon three “giants”: Descartes, Kant, and Putnam. From each, I take some ideas and discard some others, with the aim of developing a historically informed, yet original, transcendental approach to dream skepticism. I argue that dreams can be distinguished from objective cognitions, since they (...) do not regularly fulfil the transcendental conditions of such cognitions, e.g. the conditions of linguistic reference. Indeed, drawing on some insights by G. E. Moore and Wittgenstein, I further argue that the formulations of dream skepticism prove nonsensical: they cannot be linguistically understood. However, reflection on these skeptical formulations may lead us to a clear aesthetic understanding of the transcendental conditions of sense, as well as of the meaning of philosophically problematic words like “dream,” “perception,” and “reality.”.

This chapter introduces the rationalist model of delusions. It begins by presenting John Campbell’s seminal proposal that delusions are caused top-down by pathological Wittgensteinian framework or hinge beliefs. After presenting Campbell’s rationalist account of delusions, the chapter raises and examines prominent objections by Tim Bayne & Elisabeth Pacherie as well as by Tim Thornton. The former make an important distinction between the aetiological top-down cognitive part and the epistemological rationalist framework part of Campbell’s account. The thesis that delusions are caused (...) top-down by pathological beliefs is not equivalent to the thesis that delusions are Wittgensteinian framework certainties. This chapter endorses this distinction. While the arguments against the top-down aspect are found to be more convincing – which motivates popular two-factor theories – the rationalist framework model of delusions is defended as an epistemologically promising account of delusion. Finally, this chapter examines a range of developments that have been made taking Campbell’s rationalism as a starting point. Most prominently the section examines Eilan’s early development of rationalism and Rhodes and Gipps’ proposal that delusions are not framework propositions but a product of their absence. (shrink)

The paper is a partly provocative essay edited as a humanitarian study in philosophy of science and social philosophy, reflecting on the practical, “anti-metaphysical” turn taken place since the 20th century and continuing until now. The article advocates that it is about time it to be overcome because it is the main obstacle for the further development of exact and natural sciences including mathematics therefore restoring the unity of philosophy and sciences in the dawn of modern science when the great (...) scientists were philosophers as a necessary condition for their revolutionary achievements, and the physicists were simultaneously mathematicians not less than philosophers and even theologians as Descartes, Newton, Leibnitz were just as their predecessors, Copernicus or Galileo Galilei. The revolution in science accomplished by them needed philosophy since any scientific revolution, then necessarily growing into social, needs philosophy; and if ones wish to prevent social revolutions originating from fundamental scientific discoveries, in turn relying on the close link of sciences and philosophy, they are to cut the link at issue, and just that happened in the 20th centuries therefore implicitly heralding a “brave new world” of eternal normal science without revolutions whether scientific or social. Fukuyama’s “end of history” requires an “end of scientific history” as it is an obligatory premise, and separating sciences from philosophy is sufficient for that, though proclaimed quite otherwise: as overcoming metaphysics preventing sciences and substituting them by quasi-sciences. Particularly, that “anti-metaphysical turn” has established for science to obey society absolutely and thoroughly, obviously a condition contradicting the scientific and social revolutions in Modernity featured by the domination of science over society by the mediation of philosophy able to translate all epochal scientific discoveries as social corollaries. A special attention is paid to quantum mechanics, being the frontier of physics in the 20th century, where that anti-metaphysical turn is discernibly concentrated and may be notated by the famous slogan “Shut up and calculate!” regardless of its authorship. Just the revolutionary discoveries in physics, for example those of “dark mass” and “dark energy” or entanglement force now its rejection therefore restoring the unity of philosophy, mathematics and physics, made ever possible the establishment of modern science by its emancipation from religion, and thus and ind final analysis, from society.

The legacy of the Platonic dialogues may well lie, not in any classical idealist “doctrine of forms,” but in an inquisitive stance towards the puzzle behind any such doctrine—how thought can be about anything at all. This Platonic puzzle may, however, yield a different guise of idealism that is recognizably diagnostic: it aims to dispel our worry about thought’s objectivity as a confusion, engendered by a self-alienation of thought. These themes of diagnosis and idealism resurface in Wittgenstein, who in his (...) treatment of rules calls for an understanding of thought’s normativity from within. This is taken up by Cora Diamond, who urges philosophy to attend to thought’s real needs by exorcizing any desire for agreement with something other than itself. I argue that Wittgenstein and Diamond lead us back to Kant’s idealism, which identifies transcendental realism as the deep-seated prejudice at the root of the puzzle. (shrink)

In this paper I begin by explaining what epistemic injustice is and what ordinary language philosophy is. I then go on to ask why we might doubt the usefulness of ordinary language philosophy in examining epistemic injustice. In the first place, we might wonder how ordinary language philosophy can be of use, given that many of the key terms used in discussing epistemic injustice, including ‘epistemic injustice’ itself, are not drawn from our ordinary language. We might also have doubts about (...) the usefulness of ordinary language philosophy in this area, given ordinary language philosophers’ aversion to theory. Finally, we might have doubts about the usefulness of ordinary language philosophy due to the fact that the study of epistemic injustice is clearly a study of practical matters concerning the way the world is and has been historically. If ordinary language philosophy is just concerned with grammar, what use can it be to practical and social philosophy concerning current issues? In response to these worries, I demonstrate the usefulness of ordinary language philosophy in practice by applying the insights of Ludwig Wittgenstein and Alan R. White to a problem that Miranda Fricker raises, but does not answer: about whether there is a confidence condition on knowledge. I also make use of Gilbert Ryle's distinction between ‘the use of ordinary language’ and ‘the ordinary use of an expression’ to show that the terminology used in examining epistemic injustice is ordinary in some sense.
