JOHN CORCORAN AND WILIAM FRANK. Surprises in logic. Bulletin of Symbolic Logic. 19 253. Some people, not just beginning students, are at first surprised to learn that the proposition “If zero is odd, then zero is not odd” is not self-contradictory. Some people are surprised to find out that there are logically equivalent false universal propositions that have no counterexamples in common, i. e., that no counterexample for one is a counterexample for the other. Some people would be surprised (...) to find out that in normal first-order logic existential import is quite common: some universals “Everything that is S is P” —actually quite a few—imply their corresponding existentials “Something that is S is P”. Anyway, perhaps contrary to its title, this paper is not a cataloging of surprises in logic but rather about the mistakes that did or might have or might still lead people to think that there are no surprises in logic. The paper cataloging of surprises in logic is on our “to-do” list. -/- ► JOHN CORCORAN AND WILIAM FRANK, Surprises in logic. Philosophy, University at Buffalo, Buffalo, NY 14260-4150, USA E-mail: corcoran@buffalo.edu There are many surprises in logic. Peirce gave us a few. Russell gave Frege one. Löwenheim gave Zermelo one. Gödel gave some to Hilbert. Tarski gave us several. When we get a surprise, we are often delighted, puzzled, or skeptical. Sometimes we feel or say “Nice!”, “Wow, I didn’t know that!”, “Is that so?”, or the like. Every surprise belongs to someone. There are no disembodied surprises. Saying there are surprises in logic means that logicians experience surprises doing logic—not that among logical propositions some are intrinsically or objectively “surprising”. The expression “That isn’t surprising” often denigrates logical results. Logicians often aim for surprises. In fact, [1] argues that logic’s potential for surprises helps motivate its study and, indeed, helps justify logic’s existence as a discipline. Besides big surprises that change logicians’ perspectives, the logician’s daily life brings little surprises, e.g. that Gödel’s induction axiom alone implies Robinson’s axiom. Sometimes wild guesses succeed. Sometimes promising ideas fail. Perhaps one of the least surprising things about logic is that it is full of surprises. Against the above is Wittgenstein’s surprising conclusion : “Hence there can never be surprises in logic”. This paper unearths basic mistakes in [2] that might help to explain how Wittgenstein arrived at his false conclusion and why he never caught it. The mistakes include: unawareness that surprise is personal, confusing logicians having certainty with propositions having logical necessity, confusing definitions with criteria, and thinking that facts demonstrate truths. People demonstrate truths using their deductive know-how and their knowledge of facts: facts per se are epistemically inert. [1] JOHN CORCORAN, Hidden consequence and hidden independence.

Los teóricos de la democracia dejaron de lado la pregunta de quién legalmente forma parte del "pueblo" autorizado, pregunta que atraviesa a todas las teoría de la democracia y continuamente vivifica la práctica democrática. Determinar quién constituye el pueblo es un dilema inabordable e incluso imposible de responder democráticamente; no es una pregunta que el pueblo mismo pueda decidir procedimentalmente porque la propia premisa subvierte las premisas de su resolución. Esta paradoja del mandato popular revela que el pueblo para ser (...) mejor comprendido como una demanda política, como un proceso de subjetivación, surge y se desarrolla en distintos contextos democráticos. En Estados Unidos el disputado poder para hablar en beneficio del pueblo deriva de un excedente constitutivo heredado de la era revolucionaria, a partir del hecho de que desde la Revolución el pueblo ha sido por vez primera encarnado por la representación y como exceso de cualquier forma de representación. La autoridad posrevolucionaria del vox populi deriva de esa continuamente reiterada pero nunca realizada referencia a la soberanía del pueblo a partir de la representación, legitimidad a partir de la ley, espíritu a partir de la letra, la palabra a través de la palabra. Este ensayo examina la emergencia histórica de este exceso de democracia en el período revolucionario, y cómo este habilita a una subsecuente historia de "momentos constituyentes", momentos cuando subautorizados -radicales, entidades autocreadas-, se apoderan del manto de la autoridad, cambiando las reglas de la autoridad en ese proceso. Estos pequeños dramas de reclamos de autoridad política para hablar en nombre del pueblo son felices, aun cuando explícitamente rompan con los procedimientos o reglas estatuidas para representar la voz popular. -/- Momentos constituyentes: paradojas y poder popular en los Estados Unidos de América posrevolucionarios [traducción], Revista Argentina de Ciencia Política, N°15, EUDEBA, Buenos Aires, Octubre 2012, pp. 49-74.

Symposium contribution on Frank Jackson’s a priori entailment thesis – which he employs to connect metaphysics and conceptual analysis. In the book he develops this thesis within the two-dimensional framework and also proposes a formal argument for it. I argue that the two-dimensional framework doesn’t provide independent support for the a priori entailment thesis since one has to build into the framework assumptions as strong as the thesis itself.

For each positive n , two alternative axiomatizations of the theory of strings over n alphabetic characters are presented. One class of axiomatizations derives from Tarski's system of the Wahrheitsbegriff and uses the n characters and concatenation as primitives. The other class involves using n character-prefixing operators as primitives and derives from Hermes' Semiotik. All underlying logics are second order. It is shown that, for each n, the two theories are definitionally equivalent [or synonymous in the sense of deBouvere]. It (...) is further shown that each member of one class is synonymous with each member of the other class; thus that all of the theories are definitionally equivalent with each other and with Peano arithmetic. Categoricity of Peano arithmetic then implies categoricity of each of the above theories. (shrink)

This volume contains new and original papers on Martin Heidegger’s complex relation to Friedrich Nietzsche’s philosophy. The authors not only critically discuss the many aspects of Heidegger’s reading of Nietzsche, they also interpret Heidegger’s thought from a Nietzschean perspective. Here is presented for the first time an overview of not only Heidegger’s and Nietzsche’s philosophy but also an overview of what is alive – and dead – in their thinking. Many authors through a reading of Heidegger and Nietzsche deal with (...) current issues such as technology, ecology, and politics. This volume is of interest for everyone interested in Heidegger’s and Nietzsche’s thought.Contributors include: Babette Babich, Charles Bambach, Robert Bernasconi, Virgilio Cesarone, Stuart Elden, Michael Eldred, Markus Enders, Charles Feitosa, Véronique Fóti, Luanne T.

This paper draws together as many as possible of the clues and pieces of the puzzle surrounding T. S. Eliot’s “infamous” literary term “objective correlative”. Many different scholars have claimed many different sources for the term, in Pound, Whitman, Baudelaire, Washington Allston, Santayana, Husserl, Nietzsche, Newman, Walter Pater, Coleridge, Russell, Bradley, Bergson, Bosanquet, Schopenhauer and Arnold. This paper aims to rewrite this list by surveying those individuals who, in different ways, either offer the truest claim to being the source of (...) the term, or contributed the most to Eliot’s development of it: Allston, Husserl, Bradley and Bergson. What the paper will argue is that Eliot’s possible inspiration for the term is more indebted to the idealist tradition, and Bergson’s aesthetic development of it, than to the phenomenology of Husserl.

On the work of Frank Ramsey, emphasizing topics most relevant to philosophy of science.

In his contribution, Mark Alfano lays out a new (to virtue theory) naturalistic way of determining what the virtues are, what it would take for them to be realized, and what it would take for them to be at least possible. This method is derived in large part from David Lewis’s development of Frank Ramsey’s method of implicit definition. The basic idea is to define a set of terms not individually but in tandem. This is accomplished by assembling all (...) and only the common sense platitudes that involve them (e.g., typically, people want to be virtuous), conjoining those platitudes, and replacing the terms in question by existentially quantified variables. If the resulting sentence is satisfied, then whatever satisfies are the virtues. If it isn’t satisfied, there are a couple of options. First, one could just admit defeat by saying that people can’t be virtuous. More plausibly, one could weaken the conjunction by dropping a small number of the platitudes from it (and potentially adding some others). Alfano suggests that the most attractive way to do this is by dropping the platitudes that deal with cross-situational consistency and replacing them with platitudes that involve social construction: basically, people are virtuous (when they are) at least in part because other people signal their expectations of virtuous conduct, which induces virtuous conduct, which in turn induces further signals of expected virtuous conduct, and so on.

No one is quite sure what happened to T.S. Eliot in that rose-garden. What we do know is that it formed the basis for Four Quartets, arguably the greatest English poem written in the twentieth century. Luckily it turns out that Martin Heidegger, when not pondering the meaning of being, spent a great deal of time thinking and writing about the kind of event that Eliot experienced. This essay explores how Heidegger developed the concept of Ereignis, “event” which, in the (...) context of Eliot’s poetry, helps us understand an encounter with the “heart of light” a little better.

The aim of this paper is to discuss the “Austro-American” logical empiricism proposed by physicist and philosopher Philipp Frank, particularly his interpretation of Carnap’s Aufbau, which he considered the charter of logical empiricism as a scientific world conception. According to Frank, the Aufbau was to be read as an integration of the ideas of Mach and Poincaré, leading eventually to a pragmatism quite similar to that of the American pragmatist William James. Relying on this peculiar interpretation, Frank (...) intended to bring about a rapprochement between the logical empiricism of the Vienna Circle in exile and American pragmatism. In the course of this project, in the last years of his career, Frank outlined a comprehensive, socially engaged philosophy of science that could serve as a “link between science and philosophy”.

Three-dimensional material models of molecules were used throughout the 19th century, either functioning as a mere representation or opening new epistemic horizons. In this paper, two case studies are examined: the 1875 models of van ‘t Hoff and the 1890 models of Sachse. What is unique in these two case studies is that both models were not only folded, but were also conceptualized mathematically. When viewed in light of the chemical research of that period not only were both of these (...) aspects, considered in their singularity, exceptional, but also taken together may be thought of as a subversion of the way molecules were chemically investigated in the 19th century. Concentrating on this unique shared characteristic in the models of van ‘t Hoff and the models of Sachse, this paper deals with the shifts and displacements between their operational methods and existence: between their technical and epistemological aspects and the fact that they were folded, which was forgotten or simply ignored in the subsequent development of chemistry.

Martin Heidegger defines the world as ‘the ever non-objective to which we are subject as long as the paths of birth and death . . . keep us transported into Being’. He writes that the world is ‘not the mere collection of the countable or uncountable, familiar and unfamiliar things that are at hand . . . The world worlds’. Being able to fully and richly express how the world worlds is the task of the artist, whose artwork is the (...) crystallization of this ‘worlding’. For Heidegger it is especially the poet who is attuned to this ‘worlding’, for the poet’s work is focussed on and happens within language itself. The poet is a ‘world-maker’, but this ‘worlding’ is not directed at creating a fictional world; rather it is aimed at revealing the world itself, drawing to the foreground the ‘ever non-objective’ nature of the world, the world happening and unfolding through and with us. This paper, using T.S. Eliot’s poetry, particularly Four Quartets as an example, will delve into how the language of the poet is able to articulate this seemingly invisible boundary between the everyday world and that same world revealed as a mysterious potential that ‘worlds’. The ‘religious imagination’ is central in how this transformation of reality, through poetic language, can manifest. Paul Ricoeur’s work on the poetic and religious dimensions of imagination, particularly the notion of ‘hope’ provides the theoretical underpinnings to explain this transformation. (shrink)

The problem of free will is deeply linked with the causal relevance of mental events. The causal exclusion argument claims that, in order to be causally relevant, mental events must be identical to physical events. However, Gibb has recently criticized it, suggesting that mental events are causally relevant as double preventers. For Gibb, mental events enable physical effects to take place by preventing other mental events from preventing a behaviour to take place. The role of mental double preventers is hence (...) similar to what Libet names free won’t, namely the ability to veto an action initiated unconsciously by the brain. In this paper I will propose an argument against Gibb’s account, the causal irrelevance argument, showing that Gibb’s proposal does not overcome the objection of systematic overdetermination of causal relevance, because mental double preventers systematically overdetermine physical double preventers, and therefore mental events are causally irrelevant.

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)

The term ‘continuous’ in real analysis wasn’t given an adequate formal definition until 1817. However, important theorems about continuity were proven long before that. How was this possible? In this paper, I introduce and refine a proposed answer to this question, derived from the work of Frank Jackson, David Lewis and other proponents of the ‘Canberra plan’. In brief, the proposal is that before 1817 the meaning of the term ‘continuous’ was determined by a number of ‘platitudes’ which had (...) some special epistemic status. (shrink)

This thesis explores, thematically and chronologically, the substantial concordance between the work of Martin Heidegger and T.S. Eliot. The introduction traces Eliot's ideas of the 'objective correlative' and 'situatedness' to a familiarity with German Idealism. Heidegger shared this familiarity, suggesting a reason for the similarity of their thought. Chapter one explores the 'authenticity' developed in Being and Time, as well as associated themes like temporality, the 'they' (Das Man), inauthenticity, idle talk and angst, and applies them to interpreting Eliot's poem, (...) 'The Love Song of J. Alfred Prufrock'. Both texts depict a bleak Modernist view of the early twentieth-century Western human condition, characterized as a dispiriting nihilism and homelessness. Chapter two traces the chronological development of Ereignis in Heidegger's thinking, showing the term's two discernible but related meanings: first our nature as the 'site of the open' where Being can manifest, and second individual 'Events' of 'appropriation and revelation'. The world is always happening as 'event', but only through our appropriation by the Ereignis event can we become aware of this. Heidegger finds poetry, the essential example of language as the 'house of Being', to be the purest manifestation of Ereignis, taking as his examples Hölderlin and Rilke. A detailed analysis of Eliot's late work Four Quartets reveals how Ereignis, both as an ineluctable and an epiphanic condition of human existence, is central to his poetry, confirming, in Heidegger's words, 'what poets are for in a destitute time', namely to re-found and restore the wonder of the world and existence itself. This restoration results from what Eliot calls 'raid[s] on the inarticulate', the poet's continual striving to enact that openness to Being through which human language and the human world continually come to be. The final chapter shows how both Eliot and Heidegger value a genuine relationship with place as enabling human flourishing. Both distrust technological materialism, which destroys our sense of the world as dwelling place, and both are essentially committed to a genuinely authentic life, not the angstful authenticity of Being and Time, but a richer belonging which affirms our relationship with the earth, each other and our gods.

Thomas Garrigue Masaryk, later founder and President of the Republic of Czechoslovakia, studied philosophy in the University of Vienna from 1872 to 1876, where he came under the powerful influence of Franz Brentano. We survey the role of Brentano’s philosophy, and especially of his ethics, in Masaryk’s life and work.

A Study of Perennial Philosophy and Psychedelic Experience, with a Proposal to Revise W. T. Stace’s Core Characteristics of Mystical Experience ©Ed D’Angelo 2018 -/- Abstract -/- According to the prevailing paradigm in psychedelic research today, when used within an appropriate set and setting, psychedelics can reliably produce an authentic mystical experience. According to the prevailing paradigm, an authentic mystical experience is one that possesses the common or universal characteristics of mystical experience as identified by the philosopher W. T. Stace (...) in his 1960 work Mysticism and Philosophy. Stace’s common characteristics of mystical experience are the basis for the Hood Mysticism Questionnaire, which is the most widely used quantitative measure of mystical experience in experimental studies of psychedelic experience. In this paper, I trace the historical roots of Stace’s common characteristics of mystical experience back to Christian Neoplatonism and apophatic theology, and I trace those, in turn, back to Plato’s concept of the Good and to Aristotle’s concept of God as active intellect. I argue that Stace’s common characteristics of mystical experience are not universal or culturally invariant but are the product of a specifically Christian religious and moral tradition that has its roots in ancient Greek metaphysics. My paper concludes with a revised list of common characteristics of psychedelic experience that is a better candidate for a list of invariant structures of psychedelic experience than Stace’s common characteristics of Christian mystical experience.

I review Michael T. Ferejohn's "Formal Causes: Definition, Explanation, and Primacy in Socratic and Aristotelian Thought".

At a 2011 meeting of the Society of Christian Philosophers, N. T. Wright offered four reasons for rejecting the existence of soul. This was surprising, as many Christian philosophers had previously taken Wright's defense of a disembodied intermediate state as a defense of a substance dualist view of the soul. In this paper, I offer responses to each of Wright's objections, demonstrating that Wright's arguments fail to undermine substance dualism. In so doing, I expose how popular arguments against dualism fail, (...) such as dualism is merely an unwarranted influence of Greek culture on Christianity, and substance dualism is merely a soul-of-the-gaps hypothesis. Moreover, I demonstrate that Wright himself has offered a powerful reason for adopting substance dualism in his previous works. In conclusion I offer a view that explains why the human soul needs a resurrected body. (shrink)

Musical works change. Bruckner revised his Eighth Symphony. Ella Fitzgerald and many other artists have made it acceptable to sing the jazz standard “All the Things You Are” without its original verse. If we accept that musical works genuinely change in these ways, a puzzle arises: why can’t I change Bruckner’s Eighth Symphony? More generally, why are some individuals in a privileged position when it comes to changing musical works and other artifacts, such as novels, films, and games? I give (...) a view of musical works that helps to answer these questions. Musical works, on this view, are created abstract objects with no parts. The paradigmatic changes that musical works undergo are socially determined normative changes in how they should be performed. Due to contingent social practices, Bruckner, but not I, can change how his symphony should be performed. Were social practices radically different, I would be able to change his symphony. This view extends to abstract artifacts beyond music, including novels, films, words, games, and corporations. (shrink)

This paper considers the foundation of self-realization and the sense of morality that could justify Arne Naess’s claim ‘Self-realization is morally neutral,’ by focusing on the recent debate among deep ecologists. Self-realization, the ultimate norm of Naess’s ecosophy T, is the realization of the maxim ‘everything is interrelated.’ This norm seems to be based on two basic principles: the diminishing of narrow ego, and the integrity between the human and non-human worlds. The paper argues that the former is an extension (...) of Plato’s idea of self-development or self-mastery while the latter is implicit in Aristotle’s holism. It defends that Self-realization is morally neutral only if the term ‘moral’ is considered in the Kantian sense. However, Naess reluctantly distinguishes between ethics and morality, which makes his approach less credible. The paper concludes that Aristotle’s notion of eudaimonia supports Self-realization to qualify as a virtue. (shrink)

The success of the Bayesian approach to perception suggests probabilistic perceptual representations. But if perceptual representation is probabilistic, why doesn't normal conscious perception reflect the full probability distributions that the probabilistic point of view endorses? For example, neurons in MT/V5 that respond to the direction of motion are broadly tuned: a patch of cortex that is tuned to vertical motion also responds to horizontal motion, but when we see vertical motion, foveally, in good conditions, it does not look at all (...) horizontal. This article argues that the best Bayesian approach to this problem does not require probabilistic representation. (shrink)

The CRISPR system for gene editing can break, repair, and replace targeted sections of DNA. Although CRISPR gene editing has important therapeutic potential, it raises several ethical concerns. Some bioethicists worry CRISPR is a prelude to a dystopian future, while others maintain it should not be feared because it is analogous to past biotechnologies. In the scientific literature, CRISPR is often discussed as a revolutionary technology. In this paper we unpack the framing of CRISPR as a revolutionary technology and contrast (...) it with framing it as a value-threatening biotechnology or business-as-usual. By drawing on a comparison between CRISPR and the Ford Model T, we argue CRISPR is revolutionary as a product, process, and as a force for social change. This characterization of CRISPR offers important conceptual clarity to the existing debates surrounding CRISPR. In particular, conceptualizing CRISPR as a revolutionary technology structures regulatory goals with respect to this new technology. Revolutionary technologies have characteristic patterns of implementation, entrenchment, and social impact. As such, early identification of technologies as revolutionary may help construct more nuanced and effective ethical frameworks for public policy. (shrink)

The linguistic turn provided philosophers with a range of reasons for engaging in careful investigation into the nature and structure of language. However, the linguistic turn is dead. The arguments for it have been abandoned. This raises the question: why should philosophers take an interest in the minutiae of natural language semantics?

Sometimes the philosophical armchair gets bumped by empirical facts. So it is when thinking about pain. For good or ill (good, actually, as we shall see) most of us are intimately acquainted with physical pain, the kind you feel when you stand on a nail or burn your hand. And, from the armchair, it can seem blindingly obvious that pain is essentially unpleasant. There are of course unpleasant experiences that aren’t pains – nausea or itches, for example – but surely (...) there aren’t pains that don’t hurt, pains that are neutral or even pleasurable rather than unpleasant. Surely, indeed, there couldn’t be. For it is part of the very concept of a pain that a pain be unpleasant. Or so it has seemed to many. Yet over recent decades philosophers’ confidence in these putative truisms has been shaken by some fascinating cases from the clinic, the lab, and life. (shrink)

Adverbialist theories of thought such as those advanced by Hare and Sellars promise an ontologically sleek understanding of a variety of intentional states, but such theories have been largely abandoned due to the ‘many-property problem’. In an attempt to revitalize this otherwise attractive theory, in a series of papers as well as his recent book, Uriah Kriegel has offered a novel reply to the ‘many-property problem’ and on its basis he argues that ‘adverbialism about intentionality is alive and well’. If (...) true, Kriegel will have shown that the logical landscape has long been unnecessarily constrained. His key idea is that the many-property problem can be overcome by appreciating that mental states stand in the determinable–determinate relation to one another. The present paper shows that this relation can’t save adverbialism because it would require thinkers to think more thoughts than they need be thinking. (shrink)

Sometimes analogy researchers talk as if the freshness of an experience of analogy resides solely in seeing that something is like something else -- seeing that the atom is like a solar system, that heat is like flowing water, that paint brushes work like pumps, or that electricity is like a teeming crowd. But analogy is more than this. Analogy isn't just seeing that the atom is like a solar system; rather, it is seeing something new about the atom, an (...) observation enabled by 'looking' at atoms from the perspective of one's understanding of solar systems. The question for analogy researchers then is this: Where does this new knowledge about atoms come from? How can an analogy provide new knowledge and new understanding? (shrink)

In a recent paper, Melchior pursues a novel argumentative strategy against the sensitivity condition. His claim is that sensitivity suffers from a ‘heterogeneity problem:’ although some higher-order beliefs are knowable, other, very similar, higher-order beliefs are insensitive and so not knowable. Similarly, the conclusions of some bootstrapping arguments are insensitive, but others are not. In reply, I show that sensitivity does not treat different higher-order beliefs differently in the way that Melchior states and that while genuine bootstrapping arguments have insensitive (...) conclusions, the cases that Melchior describes as sensitive ‘bootstrapping’ arguments don’t deserve the name, since they are a perfectly good way of getting to know their conclusions. In sum, sensitivity doesn’t have a heterogeneity problem. (shrink)

Do we live in a computer simulation? I will present an argument that the results of a certain experiment constitute empirical evidence that we do not live in, at least, one type of simulation. The type of simulation ruled out is very specific. Perhaps that is the price one must pay to make any kind of Popperian progress.

The aim of this paper is to show that the French philosopher and historian of science Abel Rey played a more influential role in the formative phase of the Vienna Circle than hitherto supposed. On the whole, it will be argued that Rey's contribution had political impact. His interpretation of "modern physics" in 1907 in the face of the alleged "bankruptcy of science" should be appreciated as a masterpiece of applied enlightenment thought. As such, it was especially paradigmatic for Philipp (...) Frank's "positivist" defense of the theory of relativity and quantum mechanics against the irrationalist tendencies of the 1920s and 1930s.

I bet you don’t practice your philosophical intuitions. What’s your excuse? If you think philosophical training improves the reliability of philosophical intuitions, then practicing intuitions should improve them even further. I argue that philosophers’ reluctance to practice their intuitions highlights a tension in the way that they think about the role of intuitions in philosophy.

Clayton Littlejohn claims that the permissibility solution to the lottery paradox requires an implausible principle in order to explain why epistemic permissions don't agglomerate. This paper argues that an uncontentious principle suffices to explain this. It also discusses another objection of Littlejohn's, according to which we’re not permitted to believe lottery propositions because we know that we’re not in a position to know them.

This article examines one argument in favour of the position that the relational properties of mental states do not have causal powers over behaviour. This argument states that we establish that the relational properties of mental states do not have causal powers by considering cases where intrinsic properties remain the same but relational properties vary to see whether, under such circumstances, behaviour would ever vary. The individualist argues that behaviour will not vary with relational properties alone, which means that they (...) don’t have causal powers. Four replies are presented which all reject the premise that under such conditions behaviour can never be different, and each of these are refuted. The article concludes by arguing that knowing about the relational properties of mental states gives no predictive advantage over (and, in fact, is predictively worse than) knowing about the intrinsic properties of mental states plus context.

In response to Fred Adams and Charlotte Shreve’s (2016) paper entitled “What Can Synesthesia Teach Us about Higher Order Theories of Consciousness?”, previously published in Symposion, I argue that H.O.T. theory does have the resources to account for synesthesia and the specific worries that they advance in their paper, such as the relationship between concepts and experience and the ability to handle instances of ‘pop-out’ experiences.

Stephen Barker presents a novel approach to solving semantic paradoxes, including the Liar and its variants and Curry’s paradox. His approach is based around the concept of alethic undecidability. His approach, if successful, renders futile all attempts to assign semantic properties to the paradoxical sentences, whilst leaving classical logic fully intact. And, according to Barker, even the T-scheme remains valid, for validity is not undermined by undecidable instances. Barker’s approach is innovative and worthy of further consideration, particularly by those of (...) us who aim to find a solution without logical revisionism. As it stands, however, the approach is unsuccessful, as I shall demonstrate below. (shrink)

Students often invoke quantum mechanics in class or papers to make philosophical points. This tendency has been encouraged by pop culture influences like the film What the Bleep do We Know? There is little merit to most of these putative implications. However, it is difficult for philosophy teachers unfamiliar with quantum mechanics to handle these supposed implications in a clear and careful way. This paper is a philosophy of science version of MythBusters. We offer a brief primer on the nature (...) of quantum mechanics, enumerate nine of the most common implications associated with quantum mechanics, and finally clarify each implication with the facts. Our goal is to explain what quantum mechanics doesn’t show. (shrink)

Suppose you can save only one of two groups of people from harm, with one person in one group, and five persons in the other group. Are you obligated to save the greater number? While common sense seems to say ‘yes’, the numbers skeptic says ‘no’. Numbers Skepticism has been partly motivated by the anti-consequentialist thought that the goods, harms and well-being of individual people do not aggregate in any morally significant way. However, even many non-consequentialists think that Numbers Skepticism (...) goes too far in rejecting the claim that you ought to save the greater number. Besides the prima facie implausibility of Numbers Skepticism, Michael Otsuka has developed an intriguing argument against this position. Otsuka argues that Numbers Skepticism, in conjunction with an independently plausible moral principle, leads to inconsistent choices regarding what ought to be done in certain circumstances. This inconsistency in turn provides us with a good reason to reject Numbers Skepticism. Kirsten Meyer offers a notable challenge to Otsuka’s argument. I argue that Meyer’s challenge can be met, and then offer my own reasons for rejecting Otsuka’s argument. In light of these criticisms, I then develop an improved, yet structurally similar argument to Otsuka’s argument. I argue for the slightly different conclusion that the view proposed by John Taurek that ‘the numbers don’t count’ leads to inconsistent choices, which in turn provides us with a good reason to reject Taurek’s position.

This paper consists of two parts. In the first part, I give an in-depth comparison and analysis of the theories of Frank Ankersmit and Eelco Runia, in which I highlight their most important resemblances and differences. What both have in common is their notion of the presence of the past as a ‘presence in absence’. They differ, however, with respect to the character of this past and the role representation plays in making it present. Second, I also argue that (...) for both Ankersmit and Runia, the presence of the past is always the present of our past, which excludes the experience of the otherness of the past, and which opens both theories to the criticisms of being self-centered and nationalistic.

In this paper, in answering the question why Kant didn’t think very highly of music, I argue that for Kant (i) music unlike other art forms, lends itself more easily to combination judgments involving judgments of sense, which increases the propensity to make aesthetic mistakes and is ill-suited as an activity for improving one’s taste; (ii) music expresses aesthetic ideas and presents rational ideas only by taking advantage of existing associations while other art forms do so by breaking with the (...) laws of association and creating new associations. I propose that (ii) constitutes the reason why music is not a rich source for reflection and thereby cannot stimulate the enlargement of the cognitive faculties. Given that the standard Kant uses in setting up the hierarchy of fine arts in terms of their cultivating role is the enlargement of cognitive faculties, this explains why music is placed at the bottom of his hierarchy.

Some hold that proper names and indexicals are “Kaplan rigid”: they designate their designata even in worlds where the designata don’t exist. An argument they give for this is based on the analogy between time and modality. It is shown how this argument gains forcefulness at the expense of carefulness. Then the argument is criticized as forming a part of an inconsistent philosophical framework, the one with which David Kaplan and others operate. An alternative account of a certain class of (...) negative existentials is developed, one which eliminates both the inconsistency and the need for Kaplan rigidity. After all, mustn’t whatever is referred to exist? (shrink)

Define teleology as the view that requirements hold in virtue of facts about value or goodness. Teleological views are quite popular, and in fact some philosophers (e.g. Dreier, Smith) argue that all (plausible) moral theories can be understood teleologically. I argue, however, that certain well-known cases show that the teleologist must at minimum assume that there are certain facts that an agent ought to know, and that this means that requirements can't, in general, hold in virtue of facts about value (...) or goodness. I then show that even if we grant those 'ought's teleology still runs into problems. A positive justification of teleology looks like it will require an argument of this form: O(X); if X, then O(Y); therefore O(Y). But this form of argument isn't in general valid. I conclude by offering two positive suggestions for those attracted to a teleological outlook. (shrink)

The most common charge against sceptical theism is that it is too sceptical, i.e. it committed to some undesirable form of scepticism or another. I contend that Michael Bergmann’s sceptical theism isn’t sceptical enough. I argue that, if true, the sceptical theses secure a genuine victory: they prevent, for some people, a prominent argument from evil from providing any justification whatsoever to doubt the existence of God. On the other hand, even if true, the sceptical theses fail to prevent even (...) the atheist from justifiably accepting it. (shrink)

I defend Pascal's Wager from a particular way of evading it, the mixed strategy approach. The mixed strategies approach suggests that Pascal's Wager does not obligate one to believe in God, because one can get the same infinite expected utility from other strategies besides the strategy of believing in God. I will show that while there's nothing technically wrong with the mixed strategy approach, rationality requires it to be applied in such a way that Pascal's Wager doesn't lose any force.

Deliberation is often seen as the site of human freedom, but the binding power of rationality seems to imply that deliberation is, in its own way, a deterministic process. If one knows the starting preferences and circumstances of an agent, then, assuming that the agent is rational and that those preferences and circumstances don’t change, one should be in a position to predict what the agent will decide. However, given that an agent could conceivably confront equally attractive alternatives, it is (...) an open question whether rational choice theory can ever eliminate indeterminacy. The clearest support for such a limitation comes from the “Buridan’s ass” scenario, where an agent is confronted with two (or more) equally attractive/unattractive options. Does rationality by itself have the resources needed to prevent such paralysis of action? Those who cannot accept the idea of decisional impotence devise various ways to avoid it: postulating a neutral valence, tipping the utilities, positing sub-personal influences, and bunching the options. I argue that each of these responses is either unwarranted or flawed. All parties to the debate agree that, factually, paralysis of action is not a pervasive phenomenon. This is either because (i) the utilities one assigns to two or more options can never be balanced or because (ii) thanks to some non-rational faculty (say, the will), we would not be stuck even if those utilities were perfectly counterpoised. By looking critically at four untenable responses, I aim to show that (i) is often just a dogma and (ii) is by no means a silly position. (shrink)

Tarski’s Convention T—presenting his notion of adequate definition of truth (sic)—contains two conditions: alpha and beta. Alpha requires that all instances of a certain T Schema be provable. Beta requires in effect the provability of ‘every truth is a sentence’. Beta formally recognizes the fact, repeatedly emphasized by Tarski, that sentences (devoid of free variable occurrences)—as opposed to pre-sentences (having free occurrences of variables)—exhaust the range of significance of is true. In Tarski’s preferred usage, it is part of the meaning (...) of true that attribution of being true to a given thing presupposes the thing is a sentence. Beta’s importance is further highlighted by the fact that alpha can be satisfied using the recursively definable concept of being satisfied by every infinite sequence, which Tarski explicitly rejects. Moreover, in Definition 23, the famous truth-definition, Tarski supplements “being satisfied by every infinite sequence” by adding the condition “being a sentence”. Even where truth is undefinable and treated by Tarski axiomatically, he adds as an explicit axiom a sentence to the effect that every truth is a sentence. Surprisingly, the sentence just before the presentation of Convention T seems to imply that alpha alone might be sufficient. Even more surprising is the sentence just after Convention T saying beta “is not essential”. Why include a condition if it is not essential? Tarski says nothing about this dissonance. Considering the broader context, the Polish original, the German translation from which the English was derived, and other sources, we attempt to determine what Tarski might have intended by the two troubling sentences which, as they stand, are contrary to the spirit, if not the letter, of several other passages in Tarski’s corpus.

There is an important sense in which one can be sure without being certain, i.e., without assigning unit probability. I will offer an explication of this sense of sureness, connecting it with the level of credence that a rational agent would need to have to be confident that she won’t ever lose her confidence. A simple formal result then gives us an explicit formula connecting the threshold α for credence needed for confidence with the threshold needed for being sure: one (...) needs 1−(1−α) to be sure. I then suggest that stepping between α and 1−(1−α) gives a procedure that generates an interesting hierarchy of credential thresholds. (shrink)
