Halbach has argued that Tarski biconditionals are not ontologically conservative over classical logic, but his argument is undermined by the fact that he cannot include a theory of arithmetic, which functions as a theory of syntax. This article is an improvement on Halbach's argument. By adding the Tarski biconditionals to inclusive negative free logic and the universal closure of minimal arithmetic, which is by itself an ontologically neutral combination, one can prove that at least one thing exists. The (...) result can then be strengthened to the conclusion that infinitely many things exist. Those things are not just all Gödel codes of sentences but rather all natural numbers. Against this background inclusive negative free logic collapses into noninclusive free logic, which collapses into classical logic. The consequences for ontological deflationism with respect to truth are discussed. (shrink)

This papers discuss the place, if any, of Convention T (the condition of material adequacy of the proper definition of truth formulated by Tarski) in the truth-makers account offered by Kevin Mulligan, Peter Simons and Barry Smith. It is argued that although Tarski’s requirement seems entirely acceptable in the frameworks of truth-makers theories for the first-sight, several doubts arise under a closer inspection. In particular, T-biconditionals have no clear meaning as sentences about truth-makers. Thus, truth-makers theory cannot be (...) considered as the semantic theory of truth enriched by metaphysical (ontological) data. The problem of truth-makers for sentences about future events is discussed at the end of the paper. (shrink)

This article is a characteristic of Alfred Tarski's profile, seen from a personal perspective after a long visit to Berkeley, at the invitation of Jan Tarski, in the house where Alfred Tarski lived. It takes into account the scientific achievements and research results of Tarski, as well as certain impressions of the author of these memories concerning the exotic life of this great Polish logician and mathematician of the 20th century.

This article is a translation of the paper in Polish (Alfred Tarski - człowiek, który zdefiniował prawdę) published in Ruch Filozoficzny 4 (4) (2007). It is a personal Alfred Tarski memories based on my stay in Berkeley and visit the Alfred Tarski house for the invitation of Janusz Tarski.

The aim of this paper is to show that the account of objective truth taken for granted by logicians at least since the publication in 1933 of Tarski’s “The Concept of Truth in Formalized Languages” arose out of a tradition of philosophical thinking initiated by Bolzano and Brentano. The paper shows more specifically that certain investigations of states of affairs and other objectual correlates of judging acts, investigations carried out by Austrian and Polish philosophers around the turn of the (...) century, formed part of the background of views that led to standard current accounts of the objectivity of truth. It thus lends support to speculations on the role of Brentano and his heirs in contemporary logical philosophy advanced by Jan Wolenski in his masterpiece of 1989 on the Logic and philosophy in the Lvov-Warsaw School.

Logical and philosophical literature provides different classifications of reasoning. In the Polish literature on the subject, for instance, there are three popular ones accepted by representatives of the Lvov-Warsaw School: Jan Łukasiewicz, Tadeusz Czeżowski and Kazimierz Ajdukiewicz (Ajdukiewicz in Logika pragmatyczna [Pragmatic Logic]. PWN, Warsaw (1965, 2nd ed. 1974). Translated as: Pragmatic Logic. Reidel & PWN, Dordrecht, 1975). The author of this paper, having modified those classifications, distinguished the following types of reasoning: (1) deductive and (2) non-deductive, and additionally two (...) types of them in each of the two, depending on the manner of combining their premises with the conclusion through the relation of classical logical entailment. Consequently, the four types of reasoning: unilateral deductive (incl. its sub-types: deductive inference and proof), bilateral deductive (incl. complete induction), and reductive (incl. the sub-types: explanation and verification), logically nonvaluable (incl. inference by analogy, statistic inference), correspond to four operators of derivability. They are defined formally on the ground of Tarski’s axiomatic theory of deductive systems, by means of the consequence operation _Cn_ (Tarski in Monatshefte Math Phys 37:361–404, 1930a, C R Soc Sci Lett Vars 23:22–29, 1930b). Also, certain metalogical properties of these operators are given, as well as their relations with Tarski’s consequence operations \(Cn^+\) ( \(Cn^+ = Cn\) ) and dual consequences \(Cn^{-1}\) (Słupecki in Zeszyty Naukowe Uniwersytetu Wrocławskiego Seria B Nr 3:33–40, 1959, Słupecki et al. in Stud Log 29:76–123, 1971, Wybraniec-Skardowska, in: Wybraniec-Skardowska, Bryll (eds) Z badań nad teorią zdań odrzuconych [Studies in the Theory of Rejected Propositions], Series B, Studia i Monografie, Zeszyty Naukowe Wyższej Szkoły Pedagogicznej w Opolu, Opole, 1969), and \(Cn^-\) (Wójcicki in Bull Sect Log 2(2):54–57, 1973)).

This book treats ancient logic: the logic that originated in Greece by Aristotle and the Stoics, mainly in the hundred year period beginning about 350 BCE. Ancient logic was never completely ignored by modern logic from its Boolean origin in the middle 1800s: it was prominent in Boole’s writings and it was mentioned by Frege and by Hilbert. Nevertheless, the first century of mathematical logic did not take it seriously enough to study the ancient logic texts. A renaissance in ancient (...) logic studies occurred in the early 1950s with the publication of the landmark Aristotle’s Syllogistic by Jan Łukasiewicz, Oxford UP 1951, 2nd ed. 1957. Despite its title, it treats the logic of the Stoics as well as that of Aristotle. Łukasiewicz was a distinguished mathematical logician. He had created many-valued logic and the parenthesis-free prefix notation known as Polish notation. He co-authored with Alfred Tarski’s an important paper on metatheory of propositional logic and he was one of Tarski’s the three main teachers at the University of Warsaw. Łukasiewicz’s stature was just short of that of the giants: Aristotle, Boole, Frege, Tarski and Gödel. No mathematical logician of his caliber had ever before quoted the actual teachings of ancient logicians. -/- Not only did Łukasiewicz inject fresh hypotheses, new concepts, and imaginative modern perspectives into the field, his enormous prestige and that of the Warsaw School of Logic reflected on the whole field of ancient logic studies. Suddenly, this previously somewhat dormant and obscure field became active and gained in respectability and importance in the eyes of logicians, mathematicians, linguists, analytic philosophers, and historians. Next to Aristotle himself and perhaps the Stoic logician Chrysippus, Łukasiewicz is the most prominent figure in ancient logic studies. A huge literature traces its origins to Łukasiewicz. -/- This Ancient Logic and Its Modern Interpretations, is based on the 1973 Buffalo Symposium on Modernist Interpretations of Ancient Logic, the first conference devoted entirely to critical assessment of the state of ancient logic studies.

The most discussed of architectural marvels tend to be the Temple of Zeus at Olympia, the Mausoleum at Halicarnassus or the Parthenon at Athens, supposedly because they are the ones we happen to have nominated ‘world wonders’; but that doesn’t mean all the rest of temple-type sites to be found across the greater Mediterranean area have less wonder about them. On the contrary; when wanting to explore and explain the role temples played in the lives of their ‘subscribers’ and a (...) temple site’s place as often the nucleus of a community, the Serapeum at Alexandria is as excellent a piece of architecture to examine as any.

In this manuscript, published here for the first time, Tarski explores the concept of logical notion. He draws on Klein's Erlanger Programm to locate the logical notions of ordinary geometry as those invariant under all transformations of space. Generalizing, he explicates the concept of logical notion of an arbitrary discipline.

Seeing how the idea of the ‘ruler cult’ and the necessary ‘myth-making’ to establish it exists to this day, as seen with the regime of a 21st century dictator like Kim Jong-il, it would be most interesting to see what parallels exist between cases of divine leadership and what we might learn about our contemporary cult rulers when looking at the dynamics of the two-millennia-old cult of the deified Emperor Augustus. As such, I have formulated a central question that focuses (...) on the reign of Divus Augustus, and in doing so provides opportunity to extrapolate from it new insights in similar but contemporary figures of leadership. A clear case of 'to understand motives in the present, one must look at actions in the past.'. (shrink)

If Jewish Bolsheviks could put an end to the imperial rule of the Romanovs, could they pose a threat to the vision of a Third Reigh? A question the German National Socialists are likely to have asked themselves before and on the eve of plotting the rise of the Nazi regime. After all, Europe had had a long-standing relationship with blaming the Jews for the world’s miseries. A relationship Germany was ready to refuel, as indicated by German Field Marshal Walter (...) von Reichenau, when he stated that ‘the most essential aim of war against the Jewish-bolshevistic system is a complete destruction of their means of power and the elimination of Asiatic influence from the European culture.’ But the German fears of Jewish interference with their great scheme for Europe’s future, must surely have been inspired by more than just the age-old conspiratorial allegation that Jews were the main forces behind world politics. As such, this essay will seek to inspect the apparent rise of antisemitic fears at the time, and put a case forward to show how religion played into all this. (shrink)

Dit werkstuk betrekt zich op de vraag of de de facto legitimiteit van Knoet de Grote als koning van Angelsaksisch Engeland, te verklaren is aan de hand van de theorieën over legitimiteit zoals gepostuleerd door Maximilian Carl Emil Weber (1864—1920). Bestaande literatuur over Knoet de Grote zijn troonsbestijging, zoals dat van vooraanstaand 19e-eeuws historicus Edward Augustus Freeman, zou een ‘geromantiseerd’ beeld hebben geschetst van de kwestie. Dit werkstuk zal kijken of dit beeld, aan de hand van Webers theorie over waar (...) legitimiteit in gegrond kan zijn, ten eerste terecht te noemen is en, ten tweede, of het Knoets status als legitiem vorst van het ‘Angelsaksische’ volk goed kan verklaren.

I defend the proposal that certain forms of work—specifically forms that are socially necessary but involve the imposition of considerable burdens—be shared between citizens. I argue that sharing burdensome work would achieve several goals, including a more equal distribution of the benefits and burdens of work, a greater appreciation of each other's labour contributions, and an amelioration of problematic inequalities of status. I conclude by considering three objections: that sharing burdensome work would (1) involve morally unacceptable constraints on freedom, (2) (...) be prohibitively inefficient, and (3) forbid mutually advantageous trades. I argue that none of these objections succeed. (shrink)

In view of the philosophical problems that vex the debate on situated affectivity, it can seem wise to focus on simple cases. Accordingly, theorists often single out scenarios in which an individual employs a device in order to enhance their emotional experience, or to achieve new kinds of experience altogether, such as playing an instrument, going to the movies or sporting a fancy handbag. I argue that this narrow focus on cases that fit a ‘user/resource model’ tends to channel attention (...) away from more complex and also more problematic instances of situated affectivity. Among these are scenarios in which a social domain draws individuals into certain modes of affective interaction, often by way of attunement and habituation to affective styles and interaction patterns that are normative in the domain in question. This can lead to a phenomenon that is not so much ‘mind extension’ than ‘mind invasion’: affectivity is dynamically framed and modulated from without, often contrary to the prior orientations of the individuals in question. As an example, I discuss affective patterns prevalent in today’s corporate workplace. I claim that workplace affect sometimes contributes to what is effectively a ‘hack’ of employees’ subjectivity.

This article aims to present a detailed analysis of the “Christian natural philosophy” elaborated by the German humanist philosopher and theologian Otto Casmann (1562–1607) in his various works. To this end, Casmann’s general idea of philosophia Christiana is discussed and critically evaluated. Regarding natural philosophy, or physics, attention is paid mainly to topics such as cosmogony and cosmology, which Casmann promised to have developed biblically and independently of the pagan (namely Aristotelian) tradition. However, when Casmann’s natural philosophy is analyzed in (...) detail, his resolute emphasis on the literal reading of the Bible, the cornerstone of his entire concept, turns out to be problematic. Similarly, despite his resolutions, his natural‑philosophical views are, to a considerable extent, still dependent on Aristotelian terms and concepts. (shrink)

The last decade has seen an increasing number of references to quantum mechanics in the humanities and social sciences. This development has in particular been driven by Karen Barad’s agential realism: a theoretical framework that, based on Niels Bohr’s interpretation of quantum mechanics, aims to inform social theorizing. In dealing with notions such as agency, power, and embodiment as well as the relation between the material and the discursive level, the influence of agential realism in fields such as feminist science (...) studies and posthumanism has been profound. However, no one has hitherto paused to assess agential realism’s proclaimed quantum mechanical origin including its relation to the writings of Niels Bohr. This is the task taken up here. We find that many of the implications that agential realism allegedly derives from a Bohrian interpretation of quantum mechanics dissent from Bohr’s own views and are in conflict with those of other interpretations of quantum mechanics. Agential realism is at best consistent with quantum mechanics and consequently, it does not capture what quantum mechanics in any strict sense implies for social science or any other domain of inquiry. Agential realism may be interesting and thought provoking from the perspective of social theorizing, but it is neither sanctioned by quantum mechanics nor by Bohr’s authority. This conclusion not only holds for agential realism in particular, it also serves as a general warning against the other attempts to use quantum mechanics in social theorizing. (shrink)

In a number of recent philosophical debates, it has become common to distinguish between two kinds of normative reasons, often called the right kind of reasons (henceforth: RKR) and the wrong kind of reasons (henceforth: WKR). The distinction was first introduced in discussions of the so-called buck-passing account of value, which aims to analyze value properties in terms of reasons for pro-attitudes and has been argued to face the wrong kind of reasons problem. But nowadays it also gets applied in (...) other philosophical contexts and to reasons for other responses than pro-attitudes, for example in recent debates about evidentialism and pragmatism about reasons for belief. While there seems to be wide agreement that there is a general and uniform distinction that applies to reasons for different responses, there is little agreement about the scope, relevance and nature of this distinction. Our aim in this article is to shed some light on this issue by surveying the RKR/WKR distinction as it has been drawn with respect to different responses, and by examining how it can be understood as a uniform distinction across different contexts. We start by considering reasons for pro-attitudes and emotions in the context of the buck-passing account of value (§1). Subsequently we address the distinction that philosophers have drawn with respect to reasons for other attitudes, such as beliefs and intentions (§2), as well as with respect to reasons for action (§3). We discuss the similarities and differences between the ways in which philosophers have drawn the RKR/WKR distinction in these areas and offer different interpretations of the idea of a general, uniform distinction. The major upshot is that there is at least one interesting way of substantiating a general RKR/WKR distinction with respect to a broad range of attitudes as well as actions. We argue that this has important implications for the proper scope of buck-passing accounts and the status of the wrong kind of reasons problem (§4). (shrink)

This paper considers whether Marx's views about communism change significantly during his lifetime. According to the ‘standard story’, as Marx got older he dropped the vision of self-realization in labour that he spoke of in his early writings, and adopted a more pessimistic account of labour, where real freedom is achieved outside the working-day, in leisure. Other commentators, however, have argued that there is no pessimistic shift in Marx's thought on this matter. This paper offers a different reading of this (...) debate. It argues that there are two visions of the good life in Marx. However, it suggests that these two visions cannot be understood in terms of a simple shift between a ‘young’ and ‘mature’ Marx. Rather, it claims that Marx moves between these two visions throughout his writings. In this way, it suggests that Marx's intellectual development on this issue is best understood as an oscillation rather than a shift. Once this interpretive claim is advanced, the paper then moves on to consider some potential causes and implications of Marx's life-long oscillation between two different conceptions of the good life.

It can be tempting to think of affect as a matter of the present moment – a reaction, a feeling, an experience or engagement that unfolds right now. This paper will make the case that affect is better thought of as not only temporally extended but as saturated with temporality, especially with the past. In and through affectivity, concrete, ongoing history continues to weigh on present comportment. In order to spell this out, I sketch a Heidegger-inspired perspective. It revolves around (...) two claims. The first is that we should understand what Heidegger calls 'Befindlichkeit' (findingness) as radical situatedness. Affectivity is a matter of 'finding oneself' constellated – thrown – into the world in ways that outrun what an individual or collective might grasp and process. The second claim is that the temporal dimension, as a relatedness to the past, takes precedence in affect's situatedness. Key to affect is the way in which the past continues to hold sway over present comportment, collectively and individually. In order to articulate this perspective, it is important to overcome the idea that affect must be understood mainly in terms of feeling or experiential states of other kinds. Better suited to grasp the idea of findingness is the concept of 'disclosive posture', as proposed by Katherine Withy. I suggest that this notion should be put at the fore of a phenomenological approach to situated affectivity. (shrink)

This study aims to corroborate Merleau-Ponty’s interpretations of fundamental ideas from Saussure’s linguistics by linking them to works that were independently elaborated by Jan Mukařovský, Czech structuralist aesthetician and literary theorist. I provide a comparative analysis of the two authors’ theories of language and their interpretations of thought as fundamentally determined by language. On this basis, I investigate how they conceive linguistic innovation and its translation into changes in the constituted language and other social codes and institutions. I explain how (...) they elaborate on Saussure’s idea of language as a system of oppositions by interpreting cultural innovation as a systematic variation of pre-established social norms and, similarly, linguistic innovation as gesturing within language. Connectedly, I show how Mukařovský’s works help clarify Merleau-Ponty’s focus on the gestural dimension of language. By discussing the two thinkers’ arguments in favour of linguistic innovation, I explore what could be called phenomenological limits of structuralism. (shrink)

In the Critique of Gotha Programme, Karl Marx famously argues that a communist society will be characterised by the principle, ‘From each according to his abilities, to each according to his needs!’ I take up a question about this principle that was originally posed by G.A. Cohen, namely: what makes communism (so conceived) possible for Marx? In reply to this question, Cohen interprets Marx as saying that communism is possible because of limitless abundance, a view that Cohen takes to be (...) implausible for ecological reasons. I develop a new interpretation of Marx's position. On this interpretation, people in communist society achieve self-realisation through providing others with the goods and services required for their self-realisation. Coupled with a reasonably high (but not immense) development of productive power, self-realisation generates conditions in which people can produce according to their abilities and receive according to their needs. I defend this view as an interpretation of Marx and I argue that it represents a more plausible account of what makes communism possible than Cohen's interpretation in which technological advance and limitless abundance play the predominant role.

The Natural Philosophy of Jan Bayer The main focus of this study is a reconstruction of the natural philosophy of the early modern Prešov's scholar Jan (Johannes) Bayer (1630–1674), with special regard to its Mosaic profile. After a critical reading of the research done on Bayer up to this point, the author concludes that Bayer’s natural-philosophical work, as such, has not yet been satisfactorily analyzed, nor has its connection to its supposedly two most important sources, Francis Bacon and Jan Amos (...) Comenius, been sufficiently explored. The study therefore concentrates on a critical analysis of Bayer’s interpretation of creation and his natural history, which are then both situated in the philosophical context of their time. The author then notes that although Bayer’s project of erecting an original and on the (especially Aristotelian) tradition independent Mosaic natural philosophy ended in failure, the thinker’s work can be assessed as a valuable attempt to synthesize Baconian and Comenian motifs while at the same time reflecting broader intellectual contexts of the period.

Marx’s vision of unalienated production is often thought to be subject to decisive objections. This article argues that these objections rely on a misinterpretation of Marx’s position. It provides a new interpretation of Marx’s vision of unalienated production. Unlike another well-known account, it suggests that unalienated production involves realizing oneself through providing others with the goods and services they need for their self-realization. It argues that this view is appealing and that it offers a more successful response to objections than (...) previous interpretations. In doing so, it hopes to put Marx’s concern with alienation and nonalienation back on the table. (shrink)

Many philosophical discussions hinge on the concept of knowability. For example, there is a blooming literature on the so-called paradox of knowability. How to understand this notion, however? In this paper, we examine several approaches to the notion: the naive approach to take knowability as the possibility to know, the counterfactual approach endorsed by Edgington (1985) and Schlöder (2019) , approaches based on the notion of a capacity or ability to know (Fara 2010, Humphreys 2011), and finally, approaches that make (...) use of the resources of dynamic epistemic logic (van Benthem 2004, Holliday 2017).

We introduce the working concept of “affective arrangement.” This concept is the centerpiece of a perspective on situated affectivity that emphasizes relationality, dynamics, and performativity. Our proposal relates to work in cultural studies and continental philosophy in the Spinoza–Deleuze lineage, yet it is equally geared to the terms of recent work in the philosophy of emotion. Our aim is to devise a framework that can help flesh out how affectivity unfolds dynamically in a relational setting by which it is at (...) the same time modulated in recurring ways. With this orientation, this article contributes to the interdisciplinary study of situated affectivity and to the theoretical and conceptual unification of distinct strands of research from several disciplines.

I propose to open a discussion on a realist philosophy of curation. To do so, I plot premises that will move towards such a philosophy. While I am neither introducing a new ontology nor contributing to metaphysics, I deal with metaphysical and ontological issues as these engage in the philosophy of curation and the philosophy of museums. In particular, I start with a museological or curatorial realism towards a discussion on meeting curation with the broadness of reality. There are three (...) core premises. First, while reality is ontologically mind-independent, it is anti-realist for reality to be curation-dependent. Second, curation has to be folded (contrary to Deleuze’s use of dynamic folding qua ‘an origami cosmos’) to address the anti-realist connotations of curation. To do this, I methodologically introduce the fold and state two-fold, three-fold, fourfold, and fifth-fold semantics of curation. While curatorial realism can be argued in a fourfold curation, the third premise is that the realist aspect lies in the fifth-folding of curation to match the extensivity of reality. This paper will attempt to introduce the philosophy of museums and the philosophy of curation with a bent on the realism/anti-realism debate. It will expose the inherit anti-realism of curation, and survey the need for objects in metaphysics and within contemporary forms of realism. (shrink)

The goal of our article is to review the widespread anthropological figure, according to which we can achieve a better understanding of humans by contrasting them with animals. This originally Herderian approach was elaborated by Arnold Gehlen, who characterized humans as “deficient beings” who become complete through culture. According to Gehlen, humans, who are insufficiently equipped by instincts, indirectly stabilize their existence by creating institutions, i.e., complexes of habitual actions. On the other hand, Maurice Merleau-Ponty shows that corporeal relationship to (...) the world is already indirect because it is based on preestablished and readjusted “standards” or “norms” of interaction with the environment. Merleau-Ponty then calls these norms “institutions” and views culture as readjustment of institutions which operate already on the level of corporeal existence. The anthropological figure of confronting humans and animals thus cannot produce, as in Gehlen, a contrast between an allegedly “direct” relationship to the world in animals and a supposedly “indirect” relationship to the world in humans. The Herderian approach can be meaningfully retained only if interpreted as an invitation to confront the norms of indirect interaction with the world in animals and in people, that is, if viewed as a comparison of their respective institutions.

Higher-order logic, with its type-theoretic apparatus known as the simple theory of types (STT), has increasingly come to be employed in theorizing about properties, relations, and states of affairs—or ‘intensional entities’ for short. This paper argues against this employment of STT and offers an alternative: ordinal type theory (OTT). Very roughly, STT and OTT can be regarded as complementary simplifications of the ‘ramified theory of types’ outlined in the Introduction to Principia Mathematica (on a realist reading). While STT, understood as (...) a theory of intensional entities, retains the Fregean division of properties and relations into a multiplicity of categories according to their adicities and ‘input types’ and discards the division of intensional entities into different ‘orders’, OTT takes the opposite approach: it retains the hierarchy of orders (though with some modifications) and discards the categorisation of properties and relations according to their adicities and input types. In contrast to STT, this latter approach avoids intensional counterparts of the Epimenides and related paradoxes. Fundamental intensional entities lie at the base of the proposed hierarchy and are also given a prominent part to play in the individuation of non-fundamental intensional entities. (shrink)

This paper clarifies Merleau-Ponty’s original account of “higher-order” cognition as fundamentally embodied and enacted. Merleau-Ponty’s philosophy inspired theories that deemphasize overlaps between conceptual knowledge and motor intentionality or, on the contrary, focus exclusively on abstract thought. In contrast, this paper explores the link between Merleau-Ponty’s account of motor intentionality and his interpretations of our capacity to understand and interact productively with cultural symbolic systems. I develop my interpretation based on Merleau-Ponty’s analysis of two neuropathological modifications of motor intentionality, the case (...) of the brain-injured war veteran Schneider, and a neurological disorder known as Gerstmann’s syndrome. Building on my analysis of Schneider’s sensorimotor compensatory performances in relation to his limitations in the domains of algebra, geometry, and language usage, I demonstrate a strong continuity between the sense of embodiment and enaction at all these levels. Based on Merleau-Ponty’s interpretations, I argue that “higher-order” cognition is impaired in Schneider insofar as his injury limits his sensorimotor capacity to dynamically produce comparatively more complex differentiations of any given phenomenal structure. I then show how Merleau-Ponty develops and specifies his interpretation of Schneider’s intellectual difficulties in relation to the ambiguous role of the body, and in particular the hand, in Gerstmann’s syndrome. I explain how Merleau-Ponty defends the idea that sensorimotor and quasi-representational cognition are mutually irreducible, while maintaining that symbol-based cognition is a fundamentally enactive and embodied process.

Kearns (2021) reconstructs Berkeley’s (1713) Master Argument as a formally valid argument against the Materialist Thesis, with the key premise the Distinct Conceivability Thesis, namely the thesis that truths about sensible objects having or lacking thinkable qualities are (distinctly) conceivable and as its conclusion that all sensible objects are conceived. It will be shown that Distinct Conceivability Thesis entails the Reduction Thesis, which states that de dicto propositional (ordinary or distinct) conceivability reduces to de re propositional (ordinary or distinct) conceivability.

This paper is concerned with two concepts of qualitativeness that apply to intensional entities. I propose an account of pure qualitativeness that largely follows the traditional understanding established by Carnap, and try to shed light on its ontological presuppositions. On this account, an intensional entity is purely qualitative iff it does not ‘involve’ any particular. An alternative notion of qualitativeness—which I propose to refer to as a concept of strict qualitativeness—has recently been introduced by Chad Carmichael. However, Carmichael’s definition presupposes (...) a highly fine-grained conception of properties and relations. To eliminate this presupposition, I tentatively suggest a different definition that rests on a concept of perspicuous denotation. In the penultimate section, both concepts of qualitativeness are put to work in distinguishing between different ‘grades’ of qualitative discriminability. (shrink)

According to metaphysical coherentism, grounding relations form an interconnected system in which things ground each other and nothing is ungrounded. This potentially viable view’s logical territory remains largely unexplored. In this paper, I describe that territory by articulating four varieties of metaphysical coherentism.

Rather, I aim to show that not all issues which might be raised against coherentism will be equally problematic for all the versions of that view, which features far (...) more nuance and diversity than is typically ascribed to it.

Data from medical research are typically summarized with various types of outcome measures. We present three arguments in favor of absolute over relative outcome measures. The first argument is from cognitive bias: relative measures promote the reference class fallacy and the overestimation of treatment effectiveness. The second argument is decision-theoretic: absolute measures are superior to relative measures for making a decision between interventions. The third argument is causal: interpreted as measures of causal strength, absolute measures satisfy a set of desirable (...) properties, but relative measures do not. Absolute outcome measures outperform relative measures on all counts. (shrink)

By and large, the conditional connective in three-valued logic has two different functions. First, by means of a deduction theorem, it can express a specific relation of logical consequence in the logical language itself. Second, it can represent natural language structures such as "if/then'' or "implies''. This chapter surveys both approaches, shows why none of them will typically end up with a three-valued material conditional, and elaborates on connections to probabilistic reasoning.

This study clarifies the need for a renewed account of the body in physiotherapy to fill sizable gaps between physiotherapeutical theory and practice. Physiotherapists are trained to approach bodily functioning from an objectivist perspective; however, their therapeutic interactions with patients are not limited to the provision of natural-scientific explanations. Physiotherapists’ practice corresponds well to theorisation of the body as the bearer of original bodily intentionality, as outlined by Merleau-Ponty and elaborated upon by enactivists. We clarify how physiotherapeutical practice corroborates Merleau-Ponty’s (...) critical arguments against objectivist interpretations of the body; particularly, his analyses demonstrate that norms of optimal corporeal functioning are highly individual and variable in time and thus do not directly depend on generic physiological structures. In practice, objectively measurable physical deviations rarely correspond to specific subjective difficulties and, similarly, patients’ reflective insights into their own motor deficiencies do not necessarily produce meaningful motor improvements. Physiotherapeutical procedures can be understood neither as mechanical manipulations of patients’ machine-like bodies by experts nor as a process of such manipulation by way of instructing patients’ explicit conscious awareness. Rather, physiotherapeutical practice and theory can benefit from the philosophical interpretation of motor disorders as modifications of bodily intentionality. Consequently, motor performances addressed in physiotherapy are interpreted as relational features of a living organism coupled with its environment, and motor disorders are approached as failures to optimally manage the motor requirements of a given situation owing to a relative loss of the capacity to structure one’s relation with their environment through motor action. Building on this, we argue that the process of physiotherapy is most effective when understood as a bodily interaction to guide patients towards discovering better ways of grasping a situation as meaningful through bodily postures and movements.

This text addresses a problem that is not sufficiently dealt with in most of the recent literature on emotion and feeling. The problem is a general underestimation of the extent to which affective intentionality is essentially bodily. Affective intentionality is the sui generis type of world-directedness that most affective states – most clearly the emotions – display. Many theorists of emotion overlook the extent to which intentional feelings are essentially bodily feelings. The important but quite often overlooked fact is that (...) the bodily feelings in question are not the regularly treated, non-intentional bodily sensations (known from Jamesian accounts of emotion), but rather crucial carriers of world-directed intentionality. Consequently, most theories of human emotions and feelings recently advocated are deficient in terms of phenomenological adequacy. This text tries to make up for this deficit and develops a catalogue of five central features of intentional bodily feelings. In addition, Jesse Prinz’s embodied appraisal theory is criticized as an exemplary case of the misconstrual of the bodily nature of affective experience in naturalistic philosophy of mind. (shrink)

Should Marxists support universal basic income (UBI), i.e., a regular cash income paid to all without a means test or work requirement? This paper considers one important argument that they should, namely that UBI would be instrumentally effective in helping to bring about communism. It argues that previous answers to this question have paid insufficient attention to a logically prior question: what is Marx’s account of communism? In reply, it distinguishes two different accounts: a left-libertarian version that associates communism with (...) the freedom to live and work how one wants, and a perfectionist version that associates communism with the overcoming of alienated labour and self-realisation in work. It argues that UBI would make steps towards the left-libertarian account but not the perfectionist account. Ultimately, then, the question “should Marxists support basic income?” is shown to partly depend on which account of communism Marxists want to bring about. (shrink)

A many-faceted beast, the metaphysics of relations can be approached from many angles. One could begin with the various ways in which relational states are expressed in natural language. If a more historical treatment is wanted, one could begin with Plato, Aristotle, or Leibniz. In the following, I will approach the topic by first drawing on Russell’s Principles of Mathematics (1903) (still a natural-enough starting point), and then turn to a discussion mainly of positionalism. The closing section contains an overview (...) of the six contributions to this Special Issue. (shrink)

The sensorimotor theory of perceptual consciousness offers a form of enactivism in that it stresses patterns of interaction instead of any alleged internal representations of the environment. But how does it relate to forms of enactivism stressing the continuity between life and mind? We shall distinguish sensorimotor enactivism, which stresses perceptual capacities themselves, from autopoietic enactivism, which claims an essential connection between experience and autopoietic processes or associated background capacities. We show how autopoiesis, autonomous agency, and affective dimensions of experience (...) may fit into sensorimotor enactivism, and we identify differences between this interpretation and autopoietic enactivism. By taking artificial consciousness as a case in point, we further sharpen the distinction between sensorimotor enactivism and autopoietic enactivism. We argue that sensorimotor enactivism forms a strong default position for an enactive account of perceptual consciousness. (shrink)

On the standard interpretation, if a person holds cyclical preferences, the person is prone to acting irrationally. I provide a different interpretation, tying cyclical preferences not to irrationality, but to indecision. According to this alternative understanding – coined the indecision interpretation – top cycles in a person’s preferences can be associated with a difficulty in justifying one’s choice. If an agent’s justificatory impasse persists despite attempts to resolve the cycle, the agent can be deemed undecided. The indecision interpretation is compatible (...) with the standard interpretation of such cycles as instances of irrationality. Yet indecision corresponds to a first-person, non-instrumental perspective on the problem, whereas irrationality usually corresponds to a third-person, instrumental perspective. Due to these differences, interpreting cycles in terms of indecision offers a novel conceptual perspective, pertinent both for explanatory purposes and for the aim of normative theorizing. (shrink)

This paper provides an analysis of the intrinsic/extrinsic distinction, as applied both to properties and to relations. In contrast to other accounts, the approach taken here locates the source of a property’s intrinsicality or extrinsicality in the manner in which that property is ‘logically constituted’, and thus – plausibly – in its nature or essence, rather than in e.g. its modal profile. Another respect in which the present proposal differs from many extant analyses lies in the fact that it does (...) not seek to analyse the ‘global’ distinction between intrinsic and extrinsic properties on the basis of the ‘local’ distinction between having a property intrinsically and having it extrinsically. Instead, the latter distinction is explicated on the basis of the former. (shrink)

The focus of this article is the question whether the notion of being in a position to know is closed under modus ponens. The question is answered negatively.

The dilemma mentioned in the title have long been a puzzle to logic. To solve it, it was necessary to make some philosophical decisions. The article provides these decisions and discusses the way to solve the problem.

As a painfully outdated institution the school is accused of: being alienating, closing itself off to society and to the needs of young people; reproducing social inequality and consolidating existing power relations; demotivating youth; showing a lack of effectiveness and having great difficulty with employability. And last but not least, the school is considered redundant: the school, where learning is bound to time and place, is no longer needed in the digital era of virtual learning environments. The ultimate charge: the (...) school is a product of outdated ways of distributing knowledge and expertise, determined by primitive technologies of the past. Adieu school. This book advocates the acquittal of the school. It argues that many of the allegations against the school are motivated by an age-old fear and even hatred toward one of its radical but essential characteristics: that the school provides ‘free time' and transforms knowledge and skills into 'common goods', and therefore has the potential to give everyone, regardless of background, natural talent or aptitude, the time and space to leave their known environment, rise above themselves and renew (and thus change in unpredictable ways) the world. This defence of the school starts from an investigation of what makes a school a school and pinpoints why the school has value in and of itself. It reveals the various attempts to rob the school of its scholastic character, that is, to tame the school. The ultimate aim is to elaborate a touchstone that helps to defend as well as to re-invent school. -/- Jan Masschelein and Maarten Simons are members of the Laboratory for Education and Society, KU Leuven. They share an interest in research on the public dimensions of education and are currently elaborating a philosophy of schooling. (shrink)

Why are conditional degrees of belief in an observation E, given a statistical hypothesis H, aligned with the objective probabilities expressed by H? After showing that standard replies are not satisfactory, I develop a suppositional analysis of conditional degree of belief, transferring Ramsey’s classical proposal to statistical inference. The analysis saves the alignment, explains the role of chance-credence coordination, and rebuts the charge of arbitrary assessment of evidence in Bayesian inference. Finally, I explore the implications of this analysis for Bayesian (...) reasoning with idealized models in science. (shrink)

Famously, the Church–Fitch paradox of knowability is a deductive argument from the thesis that all truths are knowable to the conclusion that all truths are known. In this argument, knowability is analyzed in terms of having the possibility to know. Several philosophers have objected to this analysis, because it turns knowability into a nonfactive notion. In addition, they claim that, if the knowability thesis is reformulated with the help of factive concepts of knowability, then omniscience can be avoided. In this (...) article we will look closer at two proposals along these lines :557–568, 1985; Fuhrmann in Synthese 191:1627–1648, 2014a), because there are formal models available for each. It will be argued that, even though the problem of omniscience can be averted, the problem of possible or potential omniscience cannot: there is an accessible state at which all truths are known. Furthermore, it will be argued that possible or potential omniscience is a price that is too high to pay. Others who have proposed to solve the paradox with the help of a factive concept of knowability should take note :53–73, 2010; Spencer in Mind 126:466–497, 2017). (shrink)

According to a standard representationalist view cognitive capacities depend on internal content-carrying states. Recent alternatives to this view have been met with the reaction that they have, at best, limited scope, because a large range of cognitive phenomena—those involving absent and abstract features—require representational explanations. Here we challenge the idea that the consideration of cognition regarding the absent and the abstract can move the debate about representationalism along. Whether or not cognition involving the absent and the abstract requires the positing (...) of representations depends upon whether more basic forms of cognition require the positing of representations.
