The view of language is greatly changed from early modern philosophy to later modern philosophy and to postmodern philosophy. The linguistic question in early modern philosophy, which is characterized by rationalism and empiricism, is discussed in this paper. Linguistic phenomena are not at the center of philosophical reflections in early modern philosophy. The subject of consciousness is at the center of the philosophy, which makes language serve purely as an instrument for representing thoughts. Locke, Leibniz and Descartes consider language from (...) a representationalist point of view. To them, language itself is idealized and represents thought as if it were thought representing itself. Like the structural linguist Saussure, the founders of phenomenology and analytical philosophy give much attention to the logical or static structure of language, and stick up for the representationalism of early modern philosophy. However, their successors refuse to accept this attitude, meaning the final collapse of representationalism. (shrink)

Wittgenstein’s criticism of the notion of ‘private language’ is related to the putative centrality of “being“ and the ‘subject-predicate’ distinction. However, his efforts would prove to be more f...

The TGarden is a genre of responsive environment in which actor–spectators shape dense media sensitive to their movements. These dense fields of light, sound, and material also evolve according to their own composed dynamics, so the agency is distributed throughout the multiple media. These TGardens explore open-ended questions like the following: what makes some time-based, responsive environments compelling, and others flat? How can people improvise gestures without words, that are individually or collectively meaningful? When and how is a movement intentional, (...) or collectively intentional? This paper introduces what has been at stake behind the experimental work: subjectivation, moving from technologies of representation to technologies of performance, and the potential for ethico-aesthetic novelty.

Does Wittgenstein have a method? There are two challenges to an affirmative answer. One is put forth by Schulte, who claims that Wittgenstein’s method is little more than a skill, and thus not a method in any ambitious sense of that word. Another is Conant’s view that the philosophy of the later Wittgenstein entertains not one method, but a variety of methods. I tackle these challenges by questioning what I take to be their presupposed conceptions of ‘method’ and conclude that (...) we can indeed speak of Wittgenstein’s method in an interesting sense. Thereby, the concept of method will be elucidated and the sense in which Wittgenstein’s philosophy has a method clarified. (shrink)

According to strong pluralist theories of truth, ‘true’ designates different properties depending on which sentences it’s applied to. An influential objection to strong pluralism claims it can’t make sense of logically complex sentences whose components have different truth-properties. For example, if ‘true’ designates correspondents for ‘Tabby is a cat’, and it designates coherence for ‘Tabby is beautiful’, what does it designate for ‘Tabby is a beautiful cat’ (Tappolet 1997)? Will Gamester (2019) has proposed a novel pluralist theory meant to avoid (...) the problem. The theory construes ‘true’ as designating a different property for each possible logical structure, and he has challenged monists to identify shortcomings of the theory in virtue of its pluralism. This paper answers Gamester’s challenge and identifies three such shortcomings. (1) The theory can’t make sense of the idea that all true conjunctions share the property of having true conjuncts, in virtue of which they are true. (2) The theory imposes unmotivated syntactic constraints on the language in which the theory of truth is formulated. (3) Avoiding the second shortcoming requires arbitrary choices among equally good candidates for “the” logical form of sentences and hence the designation of ‘true’ as applied to them. (shrink)

The world or an event? Towards an ontology of war: This paper is an attempt to rethink the ontology of war. Its main object is to determine the ontological status of war and the connection between strategies of armed conflict prevention and the way this status is understood. If to overcome metaphysics we need to reconsider its basis then maybe a similar strategy should be applied in order to overcome war. The source of war is understood here not only in (...) temporal terms, but also as its essence — the ontological basis. The first part of the article invokes several conceptions from the twentieth century, according to which, war was to be overcome by variously understood progress. In those conceptions, as well as in the critical approaches from the beginning of the 21st century, war is treated as an event, a state of affairs. In the next part of my paper, based on Margaret Mead’s anthropological diagnosis, I propound a conception of war as an invention, and therefore — technology. The issue of war is further considered in the context of the twentieth-century philosophy of technology. A thesis is put forward according to which understanding the influence of techne of war over episteme should be the essence of thinking of war prevention. In this study, war is treated as a technology that determines perception. For critical reflection upon war, I use twentieth-century philosophical conceptions linking technology with cognitive processes, especially those formulated by Martin Heidegger and Marshall McLuhan.

T. Govier's description of ‘conductive argument’ and 'A priori analogy' is taken as a start to investigate non-deductive argumentation. It is here argued, that the nature of those types can be better understood when taking up a dynamic view (in addition to the usual structural view). The concepts of ‘frame’ and ‘position’ are constructed in order to establish such a twofold approach.

In this paper, I argue that an implication of the so-called ‘death of metaphysics’ is the imbrication of the normative and descriptive understandings of morality. This imbrication gives rise to a paradox, which amounts to the desire to refute both a priori moral justifications, and ‘the tyranny of the real’ or the socialisation and relativisation of our moral assertions and positions. I investigate three responses to this paradox, namely the pragmatic response, Jacques Derrida’s deconstructive response, and the ante-philosophical response, which (...) is based on the work of Jean-Luc Nancy. The reason for focusing on these three philosophical positions is that they all espouse an immanent view of morality. Through means of this analysis, I attempt to highlight the following implications of an immanently-defined moral position: the constitutive, as opposed to the pedagogical or prescriptive, nature of philosophy; the increasing focus on the performative force of doing philosophy and the importance of philosophical skill; the problematic nature of the distinctions between philosophy, moral theory, and applied ethics, and therefore also between the nature and function of morality; and the status of philosophy and moral theory as one type of praxis amongst many, rather than the definitive voice on praxis.

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.

The problem to be discussed here concerns ontology so far as it may not be formed by scientific theory. In brief terms, the problem arises in the following way. On the one hand, the world surely consists of whatever is there, irrespective of whether human beings are around or not, and irrespective especially of whether human beings have constructed any scientific theories depicting the nature of the world; on the other hand, scientific theories are subject to the limitation that we (...) can never verify them or prove them to be true, so that the ontology prescribed by scientific theory is not firmly established but is only what is attributed to the world by a fallible scientific theory at any given time. The problem could also be put in terms of ‘conceptual networks’ or in terms of language-systems. (shrink)

(A) I went to the pictures last Tuesday but I don’t believe that I did (1942, p. 543) or (B) I believe that he has gone out. But he has not (1944, p. 204) would be “absurd” (1942, p. 543; 1944, p. 204). Wittgenstein’s letters to Moore show that he was intensely interested in this discovery of a class of possibly true yet absurd assertions. Wittgenstein thought that the absurdity is important because it is “something similar to a contradiction, thought (...) it isn’t one” (1974, p. 177). What is the explanation of the absurdity of saying or believing something about myself that might be true? Wittgenstein thought that although the explanation will say “something about the logic of assertion” it will also show that “logic isn’t as simple as logicians think it is”. So although the explanation should.. (shrink)

Our goal in this paper is to experimentally investigate whether folk conceptions of explanation are psychologistic. In particular, are people more likely to classify speech acts as explanations when they cause understanding in their recipient? The empirical evidence that we present suggests this is so. Using the side-effect effect as a marker of mental state ascriptions, we argue that lay judgments of explanatory status are mediated by judgments of a speaker’s and/or audience’s mental states. First, we show that attributions of (...) both understanding and explanation exhibit a side-effect effect. Next, we show that when the speaker’s and audience’s level of understanding is stipulated, the explanation side-effect effect goes away entirely. These results not only extend the side-effect effect to attributions of understanding, they also suggest that attributions of explanation exhibit a side-effect effect because they depend upon attributions of understanding, supporting the idea that folk conceptions of explanation are psychologistic.

On reading the last sentence, did you interpret me as saying falsely that everything — everything in the entire universe — was packed into my carry-on baggage? Probably not. In ordinary language, ‘everything’ and other quantifiers (‘something’, ‘nothing’, ‘every dog’, ...) often carry a tacit restriction to a domain of contextually relevant objects, such as the things that I need to take with me on my journey. Thus a sentence of the form ‘Everything Fs’ is true as uttered in a (...) context C if and only if everything that is relevant in C satisfies the predicate ‘F’; ‘everything’ ranges just over the contextually relevant things. Such generality is restricted in a context-relative way. (shrink)

Peter Geach frequently showed the relevance of some of Frege's insights to contemporary philosophical debates, such as that which Geach called “the Frege Point” – “a proposition may occur in discourse now asserted, now unasserted, and yet be recognizably the same proposition”. Geach argued against a variety of “expressivist” accounts of certain propositions that their proponents could not explain the significance of such propositions in subordinate clauses. The paper extends Geach's argument to show that “the Frege Point” presents a powerful (...) challenge to any attempt, such as those influenced by the later Wittgenstein, to equate meaning with use.

The following considerations are to be seen in the framework of nontraditional theory of predication (NTP), which stems in its basic features from Sinowjew (cf. Sinowjew 1970, Sinowjew/Wessel 1975), and which is described in detail in Wessel 1989.

Although a considerable degree of precision has been introduced both into the formulation and the discussion of ontological theories by the use of formal methods there is still a remarkable indefiniteness about foundational issues. In particular it is not clear what an ontological category is and why we regard something as an ontological category. This is amazing given that the notion of ontological category is in fact the most basic of the whole of ontology: it is what this discipline is (...) about. (shrink)

I argue that Ludwig Wittgenstein’s idea of the metaphysical subject sheds new light on subjective qualities of experience. In this article I draw first of all on the interpretations provided by Michael Kremer and James Conant. Subsequently, I conclude that “what is it like” means primarily “what is it like to see myself as the metaphysical subject”.

This paper answers a philosophical challenge that emerges when we problematize the seemingly trivial "fact" that, on the one hand, through our senses we are presented with a realm that is not of our own making; while, on the other hand, various perceivers are acquainted with diverse presentations of this realm, depending on their perspective and cognitive machinery. The challenge is dubbed here the problem of presentations. The paper draws on the idea of situation-dependent properties proposed by Susanna Schellenberg. However, (...) the paper takes the notion of situation more seriously and introduces a number of basic notions borrowed from situated cognition—a cluster of ideas that have recently emerged in the philosophy of mind. These make it possible to introduce the perceiver in such a way as not to endanger the objective character of situation-dependent properties. Thought of this way, situation-dependent properties are in turn described as the building blocks of presentations. (shrink)

Philosophical intuition has become one of the most debated problems in recent years, largely due to the rise of the movement called experimental philosophy which challenged the conviction that philosophers have some special insight into abstract ideas such as being, knowledge, good and evil, intentional action, etc. In response to the challenge, some authors claim that there is a special cognitive faculty called philosophical intuition which delivers justification to philosophical theses, while some others deny it based on experimental results. A (...) relatively smaller group of researchers aim at clarifying what the alleged intuition is. I follow the latter path. In this paper I argue that philosophical intuition is in the first place the capacity enabling one to what I refer to as the recognition of one’s epistemic position. The latter means becoming aware of the seemingly trivial “fact” that the way in which the world manifests itself depends on the cognitive apparatus one has, thereby propelling one to draw a distinction between appearances and reality. The recognition at stake is a very specific capacity to approach the world solely as it is experienced. This capacity, I argue, is the core and the defining feature of philosophical intuition. As part of my argumentation I also distinguish between the intuition in question and its different manifestations; and then introduce a novel notion of erotetic intuition. My argument is called “old-fashion” to emphasize the fact that I draw mostly on four figures who were pivotal in the twentieth- century philosophy and whose influence on the current debate concerning philosophical intuition should be, I believe, stronger than it is; I mean Russell, Carnap, Wittgenstein, and Husserl.

Statements of degree appear to falsify basic doctrines in Tractatus Logico-Philosophicus. I offer a fresh formulation of the challenge and assess a solution proposed on Wittgenstein’s behalf by Sarah Moss. I find that Moss’s proposal fails. The proposal rides in part on novel interpretations of pronouncements by Wittgenstein on the nature of the elementary proposition. I find that the interpretations cannot be sustained but that Moss’s textual case hints at important and overlooked features of the Tractarian program. I develop Wittgenstein’s (...) comparison of propositions to measuring instruments and apply it throughout, showing that it captures philosophical commitments in Tractatus that otherwise tend to slip from view.

Traditional moral theory usually has either of two emphases: virtuous moral character or principles for distributing duties or goods. “Zone morality” introduces a third: families and businesses are systems created by the causal reciprocities of their members. These relations embody the duties and permissions of a system's moral code. Core systems satisfy basic interests and needs; we move easily among them, hardly noticing that moral demands vary from system to system. Moral conflicts arise because of discord within or among systems (...) but also because morality has three competing sites: personal attitudes and practices (benevolence or hostility), the moral codes of systems, and regulative principles that enhance social cohesion. A strong church or central government reduces conflict by imposing its rules. A democracy responds by encouraging persons and systems to participate in forums where claims are made; it promises fairness by requiring that all satisfy its legal procedures. (shrink)

Some philosophers have laid down rather severe strictures on whether there can be thought without language. Wittgenstein asserted that ‘the limits of language…mean the limits of my world’. Davidson has argued that ‘a creature cannot have thoughts unless it is an interpreter of the speech of another’. Dummett has interpreted some pronouncements as meaning that ‘the study of thought is to be sharply distinguished from the study of the psychological processes of thinking and…the only proper method of analysing thought consists (...) in the analysis of language’. And there is also the position that thought has its own language that might exist even prior to or in the absence of natural language. But here I am going to concentrate on what might be possible in the absence of natural language. I do not know what it would mean to consider thinking in the absence of its own intrinsic language, a language of thought, if the two always co-exist. (shrink)

Wiredu argues intriguingly that some philosophical questions only arise in certain linguistic settings. So philosophical questions are, on occasion, linguistically relative or, more vividly, Tongue Dependent. The phenomenon however does not rest on expressive differences between languages, or, better, on failures of translation. Though rejecting his example, I endorse the general possibility he constructs. I do so provided that there is a solution to the Paradox of Analysis. Indeed I point out that the possibility of Tongue Dependency is both necessary (...) and sufficient for a solution to the Paradox of Analysis. I then offer a solution to the Paradox of Analysis in a Fregean setting, by distinguishing within the cognitive value of a claim between cognitive accomplishment and cognitive significance. The results of analysis involve cognitive accomplishment, though have no cognitive significance. I recommend my account as dealing well with a problem Salmon raised for the Church-Frege account. Finally, I direct my account on vocabularies rather than claims and note that, though possible, actual cases of Tongue Dependency within natural languages are highly doubtful. The phenomenon does not have the cultural significance Wiredu claims for it. (shrink)

Logical structure may explain the necessity and a priori knowability of such truths as that if A is red then A is either red or green. But this explanation cannot be extended to sentences that, while necessary and knowable a priori, do not wear the appropriate logical structure on their sleeves – sentences like ''''if A is a point and A is red, then A is not green,'''' or ''''if A is a sphere, then A is not a cube.'''' The (...) real origin of these sentences'' necessity and a priori knowability is a relationship between the meanings of their component atomic sentences – a relationship which cannot be systematically reduced to logical structure by translating those atomic sentences into any kind of ''''ideal'''' language. Moreover, this kind of relationship is one to which any atomic sentences are susceptible if they have a classifying, or comparison-implying, content. Arguably, then, all atomic sentences are capable of being related to others in ways that are necessary and knowable a priori. (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)

In §93 of The Principles of Mathematics, Bertrand Russell observes that “the variable is a very complicated logical entity, by no means easy to analyze correctly”. This assessment is borne out by the fact that even now we have no fully satisfactory understanding of the role of variables in a compositional semantics for first-order logic. In standard Tarskian semantics, variables are treated as meaning-bearing entities; moreover, they serve as the basic building blocks of all meanings, which are constructed out of (...) variable assignments. But this has disquieting consequences, including Fine’s antinomy of the variable and an undue dependence of meanings on language. Here I develop an alternative, Fregean version of predicate logic that uses the traditional quantifier–variable apparatus for the expression of generality, possesses a fully compositional, non-representational semantics, and is not subject to the antinomy of the variable. The advantages of Fregean over Tarskian predicate logic are due to the former’s treating variables not as meaningful lexical items, but as mere marks of punctuation, similar to parentheses. I submit that this is indeed how the variables of predicate logic should be construed. (shrink)

ABSTRACT In this paper, I ask whether quantifiers are intensional operators, with variable assignments playing the role of indices. Certain formulations of extensional type theory suggest an affirmative answer, but the most satisfactory among them suffer from a contamination of their semantic ontology with syntactic material. I lay out ‘Fregean’ versions of extensional type theory that are free from syntactic contamination and suggest a negative answer to our question.

The main question addressed by this article is this: How should one understand the role of the sentences of the Tractatus, given Wittgenstein’s statement that they are nonsensical? I begin with a presentation of three general principles of interpretation in order to avoid answering the question in an inappropriate way. I then move on to a short presentation and commentary on a selection of readings – namely, the ineffabilist, resolute and elucidatory ones – and elaborate the answers given by advocates (...) of these to the question explored here. I agree on many points with resolute and elucidatory readings: the Tractatus presents an austere conception of nonsense, and is not a book that seeks to present ontological or semantic theories. I point out, however, that these readings cannot fully explain the nature of Tractarian elucidations. Then I discuss those parts of the Tractatus which refer to the sentences of the book itself. The main proposal of my own approach is this: Tractarian elucidations should be construed as rules of translation, in that they show how to substitute certain expressions for others. They enable us to construct a notation in which everything that is expressible in ordinary language can be said perspicuously. (shrink)

My aim in this paper is twofold: to establish that Kierkegaard's so‐called theory of the leap strongly anticipates a line of argument that is central to Wittgenstein's so‐called rule‐following considerations; and to begin to show how Kierkegaard's work has fruitful contributions of its own to make to on‐going discussions about rules and rule‐following. The paper focuses throughout on the question of how, if at all, human rule‐following can be distinguished from behaviour that is merely mechanical or instinctual. I identify a (...) central line of argument in Wittgenstein that problematizes this question by establishing the basis our ability to follow rules in our spontaneous responses. I argue that Kierkegaard not only strongly anticipates this line of argument but also offers a distinctive story about what, at bottom, makes the difference between human rule‐following and behaviour that is merely mechanical or instinctual. In a word, on Kierkegaard's story, what makes the difference is: anxiety. (shrink)

Some philosophers are metaphilosophical deflationists for metasemantic reasons. These theorists take standard philosophical assertions to be defective in some manner. There are various versions of metasemantic metaphilosophical deflationism, but a trap awaits any global version of it: metasemantics itself is a part of philosophy, so in deflating philosophy these theorists have thereby deflated the foundation of their deflationism. The present article discusses this issue and the prospects for an adequate response to the trap. Contrary to most historical responses, the article (...) argues that the best response to the trap is to adopt a local but still pervasive metasemantic deflationism. Such a response might seem ad hoc, but the article argues that the human activity of philosophy isn't a natural kind, and that a heterogeneous metaphilosophy of the appropriate kind is well motivated.

A fundamental entity is an entity that is ‘ontologically independent’; it does not depend on anything else for its existence or essence. It seems to follow that a fundamental entity is ‘modally free’ in some sense. This assumption, that fundamentality entails modal freedom (or ‘FEMF’ as I shall label the thesis), is used in the service of other arguments in metaphysics. But as I will argue, the road from fundamentality to modal freedom is not so straightforward. The defender of FEMF (...) should provide positive reasons for believing it, especially in light of recent views that are incompatible with it. I examine both direct and indirect routes to FEMF.

RÉSUMÉ: Les philosophes de la période moderne sont souvent présentés comme ayant commis une erreur élémentaire: celle de confondre la force propositionnelle avec le contenu propositionnel. Par l'examen de deux cas saillants, à savoir les philosophes de Port-Royal et John Locke, je montre que l'accusation n'est pas fondée, et que Locke en particulier a les ressources requises pour construire une théorie des attitudes propositionnelles.

Shamik Dasgupta (2016) proposes to tame the Principle of Sufficient Reason (PSR) to apply to only non-autonomous facts, which are facts that are apt for explanation. Call this strategy to tame the PSR the taming strategy. In a recent paper, Della Rocca (2020a) argues that proponents of the taming strategy, in attempting to formulate a restricted version of the PSR, nevertheless find themselves committed to endorsing a form of radical monism, which, in turn, leads right back to an untamed-PSR. Suppose, (...) for the sake of argument, that Della Rocca is right. My question is this: Is there reason to believe the principle of sufficient reason (in its untamed version)? In this paper, I argue that it is impossible for there to be a reason to believe the untamed-PSR. (shrink)

Charles Travis has developed a distinction between “the historical” and “the conceptual”, which underlies his influential contributions to the philosophy of language and perception. The distinction is based on the observation that there are, for any thought, indefinitely many different circumstances that would render it true. The generality of thoughts and concepts contrasts with the particularity of the sensible world. I challenge the assumption that what exhibits such generality cannot belong to the sensible world. I also defend a version of (...) the claim that perception involves the exercise of conceptual capacities. (shrink)

In La filosofia dell’arte, Giovanni Gentile assigned a prominent new role to the sentiments. This change struck some critics as a major departure from the earlier, classic accounts of actual idealism, in which Gentile argued that thought and language comprise the entirety of reality. Sentiments do not fit cleanly into a theory so narrowly concerned with thought and thinking. Their introduction, runs the objection, only compounds certain existing ambiguities in Gentile’s conception of the relation between mind and world. This article (...) describes and criticizes Gentile’s attempts to integrate feeling into actual idealism. It is argued that the appearance of feeling in his mature theory does not undermine but instead clarifies his views on the relation between thought and the act of thinking. Yet it also shows the strain under which idealist language was being put by the late 1920s. Gentile’s attempts to lay out a comprehensive and phenomenologically accurate account of how thinkers actually experience... (shrink)

The axiom of reducibility plays an important role in the logic of Principia Mathematica, but has generally been condemned as an ad hoc non-logical axiom which was added simply because the ramified type theory without it would not yield all the required theorems. In this paper I examine the status of the axiom of reducibility. Whether the axiom can plausibly be included as a logical axiom will depend in no small part on the understanding of propositional functions. If we understand (...) propositional functions as constructions of the mind, it is clear that the axiom is clearly not a logical axiom and in fact makes an implausible claim. I look at two other ways of understanding propositional functions, a nominalist interpretation along the lines of Landini and a realist interpretation along the lines of Linsky and Mares. I argue that while on either of these interpretations it is not easy to see the axiom as a non-logical claim about the world, there are also appear to be difficulties in accepting it as a purely logical axiom.
