The influence of Heinrich Hertz's The Principles of Mechanics on Ludwig Wittgenstein's Tractatus Logico‐Philosophicus has been studied for decades, but it has never become a mainstream topic in the Wittgensteinian literature. This paper focusses on Tractarian notions of objects, elementary facts and elementary sentences and discusses their similarities with Hertz's concepts of mass, its constituents and their mechanistic images. As the paper demonstrates, the Hertzian context provides some fruitful interpretational leads concerning several controversial ideas endorsed by early Wittgenstein, namely propositional (...) analysis, logical independence of elementary facts, logical independence of elementary sentences, and modalities.

Quine maintained that philosophical and scientific theorizing should be conducted in an untyped language, which has just one style of variables and quantifiers. By contrast, typed languages, such as those advocated by Frege and Russell, include multiple styles of variables and matching kinds of quantification. Which form should our theories take? In this article, I argue that expressivity does not favour typed languages over untyped ones.

Individual responsibility is usually articulated either in terms of an individual’s intentions or in terms of the consequences of her actions. However, many of the situations we encounter on a regular basis are structured in such a way as to render the attribution of individual responsibility unintelligible in intentional or consequential terms. Situations of this type require a different understanding of individual responsibility, which I call conditioned responsibility. The conditioned responsibility model advances that, in such situations, responsibility arises directly out (...) of the conditions in which the individual finds herself, irrespective of her intentions or of the consequences of her actions. This model gives rise to a series of challenges, some of which, I propose, can be addressed by drawing on Wittgenstein’s later notion of form of life, together with the notion of honesty implicit in his early approach to ethics.

In this paper, I want to claim that, in conformity with overall intuitions, there are some aesthetic properties that are perceivable. For they are high-level properties that are not only grasped immediately, but also attended to holistically—just like the grouping properties they depend on and that are responsible for the Gestalt effects or switches through which they are grasped. Yet, unlike such grouping properties, they are holistically attended to in a disinterested modality, where objects and their properties are regarded for (...) their own sake. (shrink)

In this paper I aim to elucidate Wittgenstein’s claim that the so-called dream argument is senseless. Unlike other interpreters, who understand the sentence “I am dreaming” as contradictory or self-defeating, I intend to elucidate in what sense one should understand it as senseless or, more precisely, as nonsensical. In this sense, I propose to understand the above-mentioned claim in light of Wittgenstein’s criticism of skepticism from the _Tractatus logico-philosophicus_ to his last writings. I intend to show that the words “I (...) am dreaming” are nonsensical in the same sense as the alleged proposition “There are physical objects” or the expression of doubt about the existence of external objects.

In this paper, we address the question of whether AI should be used for suicide prevention on social media data. We focus on algorithms that can identify persons with suicidal ideation based on their postings on social media platforms and investigate whether private companies like Facebook are justified in using these. To find out if that is the case, we start with providing two examples for AI-based means of suicide prevention in social media. Subsequently, we frame suicide prevention as an (...) issue of beneficence, develop two fictional cases to explore the scope of the principle of beneficence and apply the lessons learned to Facebook’s employment of AI for suicide prevention. We show that Facebook is neither acting under an obligation of beneficence nor acting meritoriously. This insight leads us to the general question of who is entitled to help. We conclude that private companies like Facebook can play an important role in suicide prevention, if they comply with specific rules which we derive from beneficence and autonomy as core principles of biomedical ethics. At the same time, public bodies have an obligation to create appropriate framework conditions for AI-based tools of suicide prevention. As an outlook we depict how cooperation between public and private institutions can make an important contribution to combating suicide and, in this way, put the principle of beneficence into practice.

A significant discrepancy in Wittgenstein's studies is whether Philosophical Investigations contains any trace of positive philosophy, notwithstanding the author's apparent anti-theoretic position. This study argues that the so-called ‘Chapter on philosophy’ in the Investigations §§89–133 contains negative and positive vocabulary and the use of various voices through which Wittgenstein employs his primary method of language-games, thus providing a surveyable understanding of several philosophical concepts, such as knowledge and time. His positive philosophy aims to reorient our attention from understanding the theories (...) on these concepts to understanding the concepts themselves, regardless of any theorisation. (shrink)

The present text discusses whether there is a tension between aphorisms 6.1-6.13 of the Tractatus and the Church-Turing theorem about the decidability of predicate logic. We attempt to establish the following points: (i) Aphorisms 6.1-6.13 are not consistent with the Church-Turing theorem. (ii) The logical symbolism of the Tractatus, built from the N-operator, can (and should) be interpreted as expressively complete with respect to first-order formulas. (iii) Wittgenstein’s reasons for believing that Logic is decidable were purely philosophical and the undecidability (...) result shows that there are aspects of his criticisms of Frege and Russell that become unjustified in light of these results.

This paper offers a novel interpretation of Wittgenstein’s early conception of ethics and the good ethical life. Initially, it critically examines the widespread view according to which Wittgenstein’s early conception of ethics and the good ethical life involves having a certain ethical attitude to the world. It points out that this reading incurs in some mistakes and shortcomings, thereby suggesting the need for an alternative reading that avoids and amends these inadequacies. Subsequently, it sets out to offer said reading. Specifically, (...) it is argued that the good ethical life is predicated on a good exercise of the ethical will and solving the riddle of life, both of which demand a certain view of, and not an attitude to, the world. This view is the view of the world sub specie aeterni. (shrink)

Dialetheism is the view that some contradictions are true. Resorting to either metaphysical dialetheism or semantic dialetheism may seem like an appropriate resolve to certain theological contradictions. At least for those who concede to theological contradictions, and take dialetheism seriously. However, I demonstrate that neither of these types of dialetheism would serve to be amenable in resolving an Islamic theological contradiction. This is a theological contradiction that I refer to as ‘the paradox of an unknowable and ineffable God’. As a (...) result of this, I propose an alternative type of dialetheism which aims to resolve the paradox of an unknowable and ineffable God. I call this type of dialetheism, ‘mystical dialetheism’.

The article argues for a contextualised reading of Wittgenstein’s Tractatus. It analyses in detail the role that use and application play in the text and how that supports a conception of transcendentality of logic that allows for contextualisation. The article identifies a tension in the text, between the requirement that sense be determinate and the contextual nature of application, and suggests that it is this tension that is a major driver of Wittgenstein’s later ideas.

Wittgenstein’s experiments on rhythm, conducted in Charles Myers’s laboratory in Cambridge during the years 1912–13, are his earliest recorded engagement in thinking about music, not just appreciating it, and philosophizing by means of musical thinking. In this essay, I set these experiments within their appropriate intellectual, scientific, and philosophical context in order to show that, its minor scientific importance notwithstanding, this onetime excursion into empirical research provided an early onset for Wittgenstein’s career-long exploration of the philosophically pervasive implications of aspects. (...) Dramatically moving beyond the conceptual limitations, which were inscribed by Charles Myers’s scientific program, Wittgenstein got a glimpse of a philosophical angle, which was bound to become very important to him not only in aesthetics, but also for his overarching philosophical development. He became interested in what we actually do when we re-phrase, compare, come up with good similes in order to illuminate something definite within the space of possibility, so a new aspect may come to life.

Work on the nature and scope of formal logic has focused unduly on the distinction between logical and extra-logical vocabulary; which argument forms a logical theory countenances depends not only on its stock of logical terms, but also on its range of grammatical categories and modes of composition. Furthermore, there is a sense in which logical terms are unnecessary. Alexandra Zinke has recently pointed out that propositional logic can be done without logical terms. By defining a logical-term-free language with the (...) full expressive power of first-order logic with identity, I show that this is true of logic more generally. Furthermore, having, in a logical theory, non-trivial valid forms that do not involve logical terms is not merely a technical possibility. As the case of adverbs shows, issues about the range of argument forms logic should countenance can quite naturally arise in such a way that they do not turn on whether we countenance certain terms as logical.

Categories play a major role in contemporary metaphysics. They have not only been invoked in a number of philosophical theories but are themselves objects of epistemological and metaphysical scrutiny. In this article, we will discuss the following questions: How do we know when something belongs to a certain category? Is there a fundamental category of the world? Can we give a satisfactory account of the number of categories and the completeness of systems of categories? Are categories the genuine subjects of (...) ontology? (shrink)

In recent years, philosophers have used expressions of Wittgenstein’s (e.g. “language-games,” “form of life,” and “family resemblance”) in attempts to conceive of the discipline of philosophy in a broad, open, and perhaps global way. These Wittgenstein-inspired approaches indicate an awareness of the importance of cultural and historical diversity for approaching philosophical questions. While some philosophers have taken inspiration from Wittgenstein in embracing contextualism in philosophical hermeneutics, Wittgenstein himself was more instrumental than contextual in his treatment of other philosophers; his focus (...) in his writings was on his own philosophical problems. Does this mean that Wittgensteinian philosophy is a poor resource after all for comparative, cross-cultural, or globally-engaged philosophy (i.e. if it is properly Wittgensteinian)? In this article, I examine the relevance of Wittgenstein to contextually-sensitive philosophy through studies of his conceptions of history and culture, his interest in Spengler’s philosophy of history, and recent scholarship by Hans-Johann Glock and Hans Sluga on the place of contextualism in Wittgenstein’s analysis of philosophical problems. Ultimately, this article advances the view that there are strong resources in Wittgenstein’s philosophy for those seeking a more globally-engaged approach to the field. (shrink)

In this paper I pursue two goals. Firstly, I try to evaluate how Susan Haack receives and categorically rejects Rorty's anti-epistemological message from Philosophy and the Mirror of the Nature and some subsequent writings. I reconstruct Haack's counterarguments and Rorty's responses to these counterarguments. Secondly, I propose to deconstruct the theoretical position from which Haack orchestrates her attack on Rorty. On the one hand I show that she assumes a series of classical metaphysical presuppositions that are difficult to accept today, (...) which predisposes her to a lack of hermeneutical flexibility and clarity. On the other hand, at least some of Haack's arguments against Rorty are erroneous. Following Michael Williams, I point out that Rorty's position in Mirror is not against knowledge, since it raises questions about the legitimacy of epistemology. The challenge of my approach is not to defend Rorty, but rather to examine the mechanism of a charge against him in the name of a pretended philosophical correctness. I call this type of charge “hermeneutics of annihilation”. Haack's hermeneutics of annihilation is a pseudo-hermeneutics, since her goal is not to understand the stake of Rorty's philosophy exposed in Mirror. She only understood, from the point of view of an epistemologist ideology, that this work would be a threat to Truth, Knowledge, Epistemology, Science, and Reason. (shrink)

Why did such highly abstract ideas as truth, knowledge, or justice become so important to us? What was the point of coming to think in these terms? This book presents a philosophical method designed to answer such questions: the method of pragmatic genealogy. Pragmatic genealogies are partly fictional, partly historical narratives exploring what might have driven us to develop certain ideas in order to discover what these do for us. The book uncovers an under-appreciated tradition of pragmatic genealogy which cuts (...) across the analytic-continental divide, running from the state-of-nature stories of David Hume and the early genealogies of Friedrich Nietzsche to recent work in analytic philosophy by Edward Craig, Bernard Williams, and Miranda Fricker. However, these genealogies combine fictionalizing and historicizing in ways that even philosophers sympathetic to the use of state-of-nature fictions or real history have found puzzling. To make sense of why both fictionalizing and historicizing are called for, the book offers a systematic account of pragmatic genealogies as dynamic models serving to reverse-engineer the points of ideas in relation not only to near-universal human needs, but also to socio-historically situated needs. This allows the method to offer us explanation without reduction and to help us understand what led our ideas to shed the traces of their practical origins. Far from being normatively inert, moreover, pragmatic genealogy can affect the space of reasons, guiding attempts to improve our conceptual repertoire by helping us determine whether and when our ideas are worth having.

Undoubtedly, A Priori needs to be clarified if we are to understand the heart of Critique of Pure Reason; and Kant, precisely for this very reason, devoted a considerable part of Critique to explaining the epistemic status of A Priori, searching its origin, specifying its validity scope, and illustrating its instances. Although he, more or less, in both editions of Critique, put forward some characteristics intrinsic to A Priori since they have been also used in post-Kantian traditions, especially in a (...) meaning different from what Kant meant, so they may simply bring about some confusions cause failing to appropriately grasp the heart of Critique. With reference to such confusions the authors make an attempt to shed light on this point in part. Then, in part, based on the text of Critique and its commentators’ views, authors proceed to show that to evade such confusions one should re-define necessary to “what is emerged from the nature of the human mind”, strictly universal to “applicable just in the realm of phenomenon”, pure to “merely focused on the contribution of mind itself in collaboration with the objects themselves to form empirical knowledge”, clear to “what the scope of searching for is limited to within ourselves not outside of it” and certain to “what its scope is immutable –either regarding to its instances themselves or to their numbers”. In part, by scrutinizing the other characteristic, we shall show that this characteristic, besides of referring to mere structure, can refer to some kind of knowledge on which every possible experience is based; moreover, we shall determine the relation of above characteristic to pre-Kantian traditions.

The notion of more truth, or of more truth and less falsehood, is central to epistemology. Yet, I argue, we have no idea what this consists in, as the most natural or obvious thing to say—that more truth is a matter of a greater number of truths, and less falsehood is a matter of a lesser number of falsehoods—is ultimately implausible. The issue is important not merely because the notion of more truth and less falsehood is central to epistemology, but (...) because an implicit, false picture of what this consists in underpins and gives shape to much contemporary epistemology.

A world is trivial if it makes every proposition true all at once. Such a world is impossible, an absurdity. Our world, we hope, is not an absurdity. It is important, nevertheless, for semantic and metaphysical theories that we be able to reason cogently about absurdities—if only to see that they are absurd. In this note we describe methods for ‘observing’ absurd objects like the trivial world without falling in to incoherence, using some basic techniques from modal logic. The goal (...) is to begin to locate the trivial world’s relative position in modal space; the outcome is that the less we assume about relative possibility, the more detail we can discern at the edge of reason.

RésuméPaul Boghossian soutient contre Wittgenstein que le normativisme au sujet de la logique et des mathématiques est incompatible avec le fait de tenir les énoncés logiques et mathématiques pour vrais et que le normativisme entraîne une régression indue. Je soutiens, pour ma part, que le normativisme n'entraîne pas une telle régression, parce que les normes peuvent être implicites et que le normativisme peut bien être «factualiste» si l'on rejette ce que Rockney Jacobsen appelle le «cognitivisme sémantique». Je tiens en outre (...) que la position de Boghossian repose sur la façon trompeuse dont il découpe le terrain conceptuel. (shrink)

I present a reconstruction of the logical system of the Tractatus, which differs from classical logic in two ways. It includes an account of Wittgenstein’s “form-series” device, which suffices to express some effectively generated countably infinite disjunctions. And its attendant notion of structure is relativized to the fixed underlying universe of what is named. -/- There follow three results. First, the class of concepts definable in the system is closed under finitary induction. Second, if the universe of objects is countably (...) infinite, then the property of being a tautology is \Pi^1_1-complete. But third, it is only granted the assumption of countability that the class of tautologies is \Sigma_1-definable in set theory. -/- Wittgenstein famously urges that logical relationships must show themselves in the structure of signs. He also urges that the size of the universe cannot be prejudged. The results of this paper indicate that there is no single way in which logical relationships could be held to make themselves manifest in signs, which does not prejudge the number of objects.

I argue for the Wittgensteinian thesis that mathematical statements are expressions of norms, rather than descriptions of the world. An expression of a norm is a statement like a promise or a New Year's resolution, which says that someone is committed or entitled to a certain line of action. A expression of a norm is not a mere description of a regularity of human behavior, nor is it merely a descriptive statement which happens to entail a norms. The view can (...) be thought of as a sort of logicism for the logical expressivist---a person who believes that the purpose of logical language is to make explicit commitments and entitlements that are implicit in ordinary practice. The thesis that mathematical statements are expression of norms is a kind of logicism, not because it says that mathematics can be reduced to logic, but because it says that mathematical statements play the same role as logical statements. ;I contrast my position with two sets of views, an empiricist view, which says that mathematical knowledge is acquired and justified through experience, and a cluster of nativist and apriorist views, which say that mathematical knowledge is either hardwired into the human brain, or justified a priori, or both. To develop the empiricist view, I look at the work of Kitcher and Mill, arguing that although their ideas can withstand the criticisms brought against empiricism by Frege and others, they cannot reply to a version of the critique brought by Wittgenstein in the Remarks on the Foundations of Mathematics. To develop the nativist and apriorist views, I look at the work of contemporary developmental psychologists, like Gelman and Gallistel and Karen Wynn, as well as the work of philosophers who advocate the existence of a mathematical intuition, such as Kant, Husserl, and Parsons. After clarifying the definitions of "innate" and "a priori," I argue that the mechanisms proposed by the nativists cannot bring knowledge, and the existence of the mechanisms proposed by the apriorists is not supported by the arguments they give.

The paper considers one of the most enigmatic problems of Wittgenstein`s Tractatus - the problem of solipsism. The authorś task is to reveal how the discussion of solipsism illuminates Wittgenstein`s metaphysical view in this treatise. Wittgenstein`s method is considered as one through which the status of what cannot be said is demonstrated. Wittgenstein has not embrased solipsism or idealism in the Tractatus, and neither has he rejected metaphysics as a whole. His attack has been directed against dogmatic philosophy and ethics, (...) against the effort to say what cannot be said in true/false propositions. The discussion of solipsism brings into philosophy the importance of metaphysical "I" as a transcendental limit of the world and language. Wittgenstein`s aim in the Tractatus has been twofold: a) to show the nonsensicality of philosophical, ethical, aesthetical propositions , b) to emphasize, that the inexpresibility of the higher is the most important thing in our lives.

Ostensibly, Wittgenstein’s last remarks published in 1969 under the title On Certainty are about epistemology, more precisely about the problem of scepticism. This is the standard interpretation of On Certainty. But I contend, in this paper, that we will get closer to Wittgenstein’s intentions and perhaps find new and illuminating ways to interpret his late contribution if we keep in mind that his primary goal was not to provide an answer to scepticism. In fact, I think that the standard reading (...) leads to a distorted view of Wittgenstein’s contribution in On Certainty. In order to see that, scepticism will first be briefly characterised, and then I will attempt to circumscribe more precisely the standard reading of On Certainty. In section 4, three exegetical arguments against the standard reading are offered – the hope being that the weight of these three arguments, taken together, instils doubt in the reader’s mind about the correctness of the standard reading. The paper concludes with an attempt to gesture at the philosophical significance of On Certainty once we set aside the standard reading. (shrink)

Between April and November 1912, Bertrand Russell and Ludwig Wittgenstein were engaged in a joint philosophical program. Wittgenstein‘s meeting with Gottlob Frege in December 1912 led, however, to its dissolution – the joint program was abandoned. Section 2 of this paper outlines the key points of that program, identifying what Russell and Wittgenstein each contributed to it. The third section determines precisely those features of their collaborative work that Frege criticized. Finally, building upon the evidence developed in the preceding two (...) sections, section 4 recasts along previously undeveloped lines Wittgenstein‘s logical–philosophical discoveries in the two years following his encounter with Frege in 1912. The paper concludes, in section 5, with an overview of the dramatic consequences the Frege-Wittgenstein critique had for Russell‘s philosophical development. (shrink)

Wittgenstein held that Russell’s multiple relation theory of judgment fails to explain an atomic judgment’s representation of entities as combined. He demonstrated this failure as follows. Under the multiple relation theory, an atomic judgment is a complex whose relating relation is judgment, the universal, and whose terms include the entities the judgment represents as combined. Taking such a complex we may arrive through the substitution of constituents at a complex whose relating relation is again judgment but whose terms do not (...) include entities which are logically suited for combination. This second judgment complex will not represent any of its terms as combined, for entities that are logically uncombinable are unrepresentable as combined. Russell’s theory does not, however, explain how the original judgment differs from the complex arrived at by the substitution of constituents such that the former but not the latter represents certain of its terms as combined.

When it comes to Wittgenstein's philosophy of mathematics, even sympathetic admirers are cowed into submission by the many criticisms of influential authors in that field. They say something to the effect that Wittgenstein does not know enough about or have enough respect for mathematics, to take him as a serious philosopher of mathematics. They claim to catch Wittgenstein pooh-poohing the modern set-theoretic extensional conception of a real number. This article, however, will show that Wittgenstein's criticism is well grounded. A real (...) number, as an 'extension', is a homeless fiction; 'homeless' in that it neither is supported by anything nor supports anything. The picture of a real number as an 'extension' is not supported by actual practice in calculus; calculus has nothing to do with 'extensions'. The extensional, set-theoretic conception of a real number does not give a foundation for real analysis, either. The so-called complete theory of real numbers, which is essentially an extensional approach, does not define (in any sense of the word) the set of real numbers so as to justify their completeness, despite the common belief to the contrary. The only correct foundation of real analysis consists in its being 'existential axiomatics'. And in real analysis, as existential axiomatics, a point on the real line need not be an 'extension'.

Along with offering an historically-oriented interpretive reconstruction of the syntax of PM ( rst ed.), I argue for a certain understanding of its use of propositional function abstracts formed by placing a circum ex on a variable. I argue that this notation is used in PM only when de nitions are stated schematically in the metalanguage, and in argument-position when higher-type variables are involved. My aim throughout is to explain how the usage of function abstracts as “terms” (loosely speaking) is (...) not inconsistent with a philosophy of types that does not think of propositional functions as mind- and language-independent objects, and adopts a nominalist/substitutional semantics instead. I contrast PM’s approach here both to function abstraction found in the typed λ-calculus, and also to Frege’s notation for functions of various levels that forgoes abstracts altogether, between which it is a kind of intermediary.

In much educational theory there is concern about claims that the concept of truth has no place anymore in educational thinking. These claims are generally identified as ‘postmodernist’ or ‘poststructuralist’. The fear is that when abandoning the quest for truth we enter the domain of mere belief, and in this way leave education without firm grounds. In this article I examine some examples of what is often crudely lumped together as ‘postmodernist’ educational research. What is at stake here, I argue, (...) is not so much a rejection of the quest for truth as rather a shift of focus to a different set of questions and interests: for example, existential questions. Against the contemporary, dominant focus on evidence-based practice, which conceals the person behind the method (textbook, rules, techniques), here the embodied person with her individual investment in education is brought into the light again.

On the assumption that theistic religious commitment takes place in the face of evidential ambiguity, the question arises under what conditions it is permissible to make a doxastic venture beyond one’s evidence in favour of a religious proposition. In this paper I explore the implications for orthodox theistic commitment of adopting, in answer to that question, a modest, moral coherentist, fideism. This extended Jamesian fideism crucially requires positive ethical evaluation of both the motivation and content of religious doxastic ventures. I (...) suggest that, even though the existence of horrendous evil does not resolve evidential ambiguity in favour of atheism, there are reasonable value commitments that would preclude those who hold them from satisfying extended Jamesian fideist conditions for committing themselves to classical theism. I then begin a discussion of a possible revisionary theistic alternative (in the Christian tradition) which – one might hope – may meet those conditions. An earlier, shorter, version of this paper was delivered as a keynote address at the APA Pacific 2007 Mini-Conference on Models of God. (shrink)

Philosophical Investigations, EarlyView.

In this article I explore some implications of the correspondence that went on between Ludwig Wittgenstein and the logician and mathematician Gottlob Frege. Part of this exchange was focused on the envisaged publication of Wittgenstein’s Tractatus Logico-Philosophicus, and on the philosophical or literary character of that work. The problem discussed concerned the question of whether the Tractatus should be seen not as a scientific but as an artistic achievement. My first goal is to present what, given Frege’s writings, his phrase (...) “an artistic rather than a scientific achievement” could be understood to mean in terms of the Tractatus itself. Secondly, I seek to determine the extent to which traces of Frege’s understanding of such terms as “mock thoughts,” “fiction,” “elucidation,” “paintings” and “colouring” are to be found in the language of the Tractatus. This should then make it possible to show how Wittgenstein’s work, viewed from a Fregean perspective, can be seen as furnishing a logic and semantics not only for the languages of logic and natural science, but also for something that is “an artistic rather than a scientific achievement”, while also indicating that the content of the Tractatus as a whole could not have been captured independently of the unified form Wittgenstein himself gave it.

RESUMEN En este artículo trato de establecer que, según el Tractatus, la posibilidad de pensar que el espacio lógico fuera vacío es equivalente a la posibilidad de pensar que el mundo no hubiera existido. Tal representación viene dada por la última línea de una tabla de verdad que es una descripción completa del espacio lógico: es la línea en la que todas las proposiciones elementales son falsas. En primer lugar, argumentaré que una proposición elemental sería falsa -más que no tener (...) un valor de verdad- si fuera evaluada con respecto a un mundo posible en el que alguno de los objetos nombrados en esa proposición no existe. A continuación, tendré que mostrar que es posible que los objetos tractarianos no hubieran existido para poder concluir que es posible pensar que los objetos tractarianos no hubieran existido. Por último, estoy obligado a ofrecer una nueva interpretación del pasaje sobre la substancia.ABSTRACT In this paper I intend to establish that, according to the Tractatus, the possibility of thinking that the logical space were empty is equivalent to the possibility of thinking that the world had not existed. Such a representation is given by the bottom line of a truth-table which is a complete description of logical space: it is the line where all elementary propositions are false. Firstly, I will argue that an elementary proposition would be false -rather than lacking a truth-value- if it were evaluated with respect to a possible world in which some named object in that proposition does not exist. Then I will have to show that it is possible that the tractarian objects had not existed in order to conclude that it is possible to think that the tractarian objects had not existed. Finally, I am bound to offer a new interpretation of the substance passage. (shrink)

Proposition 5.122 of Wittgenstein’s Tractatus has been the source of much puzzlement among interpreters, so much so that no fully satisfactory account is yet available. This is unfortunate, if only because the containment account of logical consequence has a venerable tradition behind it. Pasquale Frascolla’s interpretation of proposition 5.122 is based on a valid argument and one true premise. However, the argument explains sense containment only in an indirect way, leaving some crucial questions unanswered. Besides, Frascolla does not address the (...) issue of how to make sense containment notationally perspicuous, an essential theme in Wittgenstein’s reflections. In this paper, we elaborate on Frascolla’s account by looking at the issue through the Tractarian notion of logical space. Our analysis shows that, for containment to be fully appreciated, one should adopt a negative perspective on the notion of sense, in line with the exclusionary theory of conceptual content, as labelled by Ian Rumfitt. Besides this, we introduce and discuss two methods—one envisaged by Wittgenstein himself—for making sense containment notationally perspicuous. (shrink)

Frege's philosophical writings, including the “logistic project,” acquire a new insight by being confronted with Kant's criticism and Wittgenstein's logical and grammatical investigations. Between these two points a non-formalist history of logic is just taking shape, a history emphasizing the Greek and Kantian inheritance and its aftermath. It allows us to understand the radical change in rationality introduced by Gottlob Frege's syntax. This syntax put an end to Greek categorization and opened the way to the multiplicity of expressions producing their (...) own intelligibility. This article is based on more technical analyses of Frege which Claude Imbert has previously offered in other writings. (shrink)

This paper investigates Wittgenstein's "notorious" criticism of Russell's theory of judgment. Instead of advancing a further new interpretation of it, though, I analyze and discuss some of the most promising readings of the Russell/Wittgenstein dispute put forward in the secondary literature; I aim to show that, despite their alleged reciprocal opposition, they cohere with each other because they are, at bottom, different ways of highlighting the same question. I then connect Wittgenstein's criticism of Russell to the account of the nature (...) of the proposition presented in the Tractatus, arguing that the latter can be seen as a natural development of the former. Finally, I make a quick connection between Wittgenstein's criticism of Russell and the conception of the world as the totality of facts, as presented in the Tractatus. (shrink)

In this paper I explore a neglected discussion of vagueness put forward by Wittgenstein in his Philosophical Grammar (1932–34). In this work, unlike Philosophical Investigations (1953), Wittgenstein not only discusses the venerable Sorites paradox but provides a novel conception of vagueness using an analogy with coin tossing and converging intervals. As he sees it, the problematic picture of vagueness arises because we conflate aspects of the functioning of vague concepts with those of non-vague ones. Thus, while we accept that vague (...) concepts have no sharp cut-off points (are boundaryless), we nevertheless retain the idea that we can progress towards the penumbra the way we progress towards the cut-off points of non-vague concepts. As a potential remedy, Wittgenstein's analogy with coin tossing and converging intervals replaces this picture and provides an understanding of the functioning of vague concepts in which no notion of a progression arises.

This paper aims to argue against the resolute reading, and offer a correct way of reading Wittgenstein'sTractatus. According to the resolute reading, nonsense can neither say nor show anything. The Tractatus does not advance any theory of meaning, nor does it adopt the notion of using signs in contravention of logical syntax. Its sentences, except a few constituting the frame, are all nonsensical. Its aim is merely to liberate nonsense utterers from nonsense. I argue that these points are either not (...) distinctive from standard interpretations or incorrect. Instead, the Tractarian elucidations help to shed light on the nature of language and logic, and introduce the correct method in philosophy. Philosophy deals with philosophical utterances and Tractarian elucidations by pointing out that they are nonsensical. By doing this, one is helped to see that what they appear to be saying is shown by significant propositions saying something else. (shrink)

The paper tries to understand the relationship between the individual and the community where the individual belongs within Wittgenstein’s notion of the self. Wittgenstein denied the existence of the objective self, the self as an independent entity, to define human subjectivity throughout his writings. However, he has not given any positive idea about the self. The rejection of self can be seen as a denial of the autonomy of the individual, which can be understood as an individual is an aggregate (...) of facts and a fabrication of society based on the rules and world-picture she inherits. Nevertheless, there is evidence in his writings and remarks that he accepted that the individual is free to choose and make decisions concerning religion and ethics, which he considered very important in life. This paper explores how these two seemingly contrary notions can exist together. It also examines the idea of autonomy and subjectivity advocated by the early and later Wittgenstein. (shrink)

This essay explores the idea of acting from knowledge. This idea is a thought of ourselves: the distinctive way in which we act, in which we live, resides in this, that our actions, our life, may rest on knowledge. Yet the idea of action resting on knowledge is puzzling, even mysterious. The difficulty springs from the character of judgment that is knowledge: its objectivity. The objectivity of a judgment is a character of its validity: it is objectively valid. Yet it (...) is equally, and therefore, a character of the source of the reality of a valid judgment: a judgment that is knowledge is explained by nothing other than that which constitutes its validity. Now, action from knowledge partakes of this character of the knowledge on which it rests: it is explained by nothing other than what constitutes its validity, that is, its goodness. This dissolves the idea that action springs from a natural power, a power of change, a physis. That is the mystery. What could action be but the act of a natural power, and what could we be but agents of such a power? (shrink)

This paper is an attempt at bringing out various aesthetically relevant points alluded to by Wittgenstein in what I call ‘the Engelmann remark’ – a longish manuscript remark written by Wittgenstein in 1930 and painstakingly discussed by Michael Fried in the context of elucidating what is strikingly new in the work of a photographer like Jeff Wall. One part of this paper is dedicated to summarizing and briefly examining the account given by Fried while another part is meant to clarify (...) some of Wittgenstein’s points by way of contrasting their import with the story told by Fried. In this second part Wittgenstein’s late observations on aspect change are used to show in which ways these observations may help us to gain a better understanding of the idea of a specific ‘perspective’ claimed to go with a given work of art.
