Cover versions form a loose but identifiable category of tracks and performances. We distinguish four kinds of covers and argue that they mark important differences in the modes of evaluation that are possible or appropriate for each: mimic covers, which aim merely to echo the canonical track; rendition covers, which change the sound of the canonical track; transformative covers, which diverge so much as to instantiate a distinct, albeit derivative song; and referential covers, which not only instantiate a distinct song, (...) but for which the new song is in part about the original song. In order to allow for the very possibility of transformative and referential covers, we argue that a cover is characterized by relation to a canonical track rather than merely by being a new instance of a song that had been recorded previously. (shrink)

A recording or performance of a song is a cover if there is an earlier, canonical recording of the song. It can seem intuitive to think that properly appreciating a cover requires considering it in relation to the original, or at least that doing so will yield a deeper appreciation. This intuition is supported by some philosophical accounts of covers. And it is complicated by the possibility of hearing in, whereby one hears elements of the original version in the cover. (...) We argue that it can nevertheless be just as legitimate to consider a cover version on its own as it is to consider it in relation to the earlier recording that it is covering. In some cases, these two modes of appreciation will offer distinct rewards. In other cases, one mode will be substantially more rewarding than the other. The details matter, especially in complicated cases like covers of covers, but neither mode is privileged in principle. (shrink)

A brief overview of _A Philosophy of Cover Songs_, highlighting some of the main themes in the book. The first part addresses the nature of covers and makes some important initial distinctions. The second part addresses the appreciation and evaluation of covers. The third part addresses covers as a clue to the ontology of songs. Written to introduce a session at the American Society for Aesthetics Rocky Mountain Division meeting in Santa Fe, New Mexico (July 13, 2024).

Typical discussions of virtual reality (VR) fixate on technology for providing sensory stimulation of a certain kind. They thus fail to understand reality as the place wherein we live and work, misunderstanding it instead as merely a sort of presentation. The first half of the paper examines popular conceptions of VR. The most common conception is a shallow one according to which VR is a matter of simulating appearances. Yet there is, even in popular depictions, a second, more subtle conception (...) according to which VR is a matter of facilitating new kinds of interaction. The latter half of the paper turns to questions about the contemporary technology of Internet chatrooms. The fact that chatrooms can be used in certain ways suggests something about the prospects for VR. The penultimate section asks whether chatrooms may legitimately be thought of as places. (In a sense, they may.) The final section asks whether cybersex may legitimately be thought of as sex. (Again, yes.) Chatroom technology thus provides an argument for the second conception of VR over its much ballyhooed rival. (shrink)

Some scientific categories seem to correspond to genuine features of the world and are indispensable for successful science in some domain; in short, they are natural kinds. This book gives a general account of what it is to be a natural kind and puts the account to work illuminating numerous specific examples.

Cover songs are a familiar feature of contemporary popular music. Musicians describe their own performances as covers, and audiences use the category to organize their listening and appreciation. However, until now philosophers have not had much to say about them. This book explores how to think about covers, appreciating covers, and the metaphysics of covers and songs. Along the way, it explores a range of issues raised by covers, from the question of what precisely constitutes a cover, to the history (...) and taxonomy of the category, the various relationships that hold between songs, performances, and tracks, and the appreciation and evaluation of covers. (shrink)

Although some authors hold that natural kinds are necessarily relative to disciplinary domains, many authors presume that natural kinds must be absolute, categorical features of the reality —often assuming that without even mentioning the alternative. Recognizing both possibilities, one may ask whether the difference especially matters. I argue that it does. Looking at recent arguments about natural kind realism, I argue that we can best make sense of the realism question by thinking of natural kindness as a relation that holds (...) between a category and a domain. (shrink)

When we ask what natural kinds are, there are two different things we might have in mind. The first, which I’ll call the taxonomy question, is what distinguishes a category which is a natural kind from an arbitrary class. The second, which I’ll call the ontology question, is what manner of stuff there is that realizes the category. Many philosophers have systematically conflated the two questions. The confusion is exhibited both by essentialists and by philosophers who pose their accounts in (...) terms of similarity. It also leads to misreading philosophers who do make the distinction. Distinguishing the questions allows for a more subtle understanding of both natural kinds and their underlying metaphysics. (shrink)

On-line, just as off-line, there are ways of assessing the credibility of information sources. The Internet, although it arguably makes for nothing wholly new in this regard, complicates the ordinary task of assessing credibility. In the first section, I consider a specific example and argue that Internet content providers have no clear interest in resolving these comlications. In the second, I consider four general ways that we might assess credibility and explore how they apply to life online. Finally, I argue (...) that even careful information gathering may pose subtle pitfalls but that some of these may be mitigated on-line. (shrink)

This paper argues against the common, often implicit view that theories are some specific kind of thing. Instead, I argue for theory concept pluralism: There are multiple distinct theory concepts which we legitimately use in different domains and for different purposes, and we should not expect this to change. The argument goes by analogy with species concept pluralism, a familiar position in philosophy of biology. I conclude by considering some consequences for philosophy of science if theory concept pluralism is correct.

This is an open-access introductory logic textbook, prepared by Jonathan Ichikawa, based on P.D. Magnus's forallx. This (v2.0, July 2020) is intended as a stable, ready-for-teaching edition.

The accepted narrative treats John Stuart Mill’s Kinds as the historical prototype for our natural kinds, but Mill actually employs two separate notions: Kinds and natural groups. Considering these, along with the accounts of Mill’s nineteenth-century interlocutors, forces us to recognize two distinct questions. First, what marks a natural kind as worthy of inclusion in taxonomy? Second, what exists in the world that makes a category meet that criterion? Mill’s two notions offer separate answers to the two questions: natural groups (...) for taxonomy and Kinds for ontology. This distinction is ignored in many contemporary debates about natural kinds and is obscured by the standard narrative that treats our natural kinds just as a development of Mill’s Kinds. (shrink)

Given the fact that many people use Wikipedia, we should ask: Can we trust it? The empirical evidence suggests that Wikipedia articles are sometimes quite good but that they vary a great deal. As such, it is wrong to ask for a monolithic verdict on Wikipedia. Interacting with Wikipedia involves assessing where it is likely to be reliable and where not. I identify five strategies that we use to assess claims from other sources and argue that, to a greater of (...) lesser degree, Wikipedia frustrates all of them. Interacting responsibly with something like Wikipedia requires new epistemic methods and strategies. (shrink)

Sol LeWitt is probably most famous for wall drawings. They are an extension of work he had done in sculpture and on paper, in which a simple rule specifies permutations and variations of elements. With wall drawings, the rule is given for marks to be made on a wall. We should distinguish these algorithmic works from impossible-to-implement instruction works and works realized by following preparatory sketches. Taking the core feature of a wall drawing to be that it is algorithmic, some (...) of LeWitt's later works are wall drawings in name only. (shrink)

forall x: Calgary is a full-featured textbook on formal logic. It covers key notions of logic such as consequence and validity of arguments, the syntax of truth-functional propositional logic TFL and truth-table semantics, the syntax of first-order (predicate) logic FOL with identity (first-order interpretations), symbolizing English in TFL and FOL, and Fitch-style natural deduction proof systems for both TFL and FOL. It also deals with some advanced topics such as modal logic, soundness, and functional completeness. Exercises with solutions are available. (...) It is provided in PDF (for screen reading, printing, and a special version for dyslexics), HTML, and in LaTeX source code. (shrink)

The underdetermination of theory by evidence is supposed to be a reason to rethink science. It is not. Many authors claim that underdetermination has momentous consequences for the status of scientific claims, but such claims are hidden in an umbra of obscurity and a penumbra of equivocation. So many various phenomena pass for `underdetermination' that it's tempting to think that it is no unified phenomenon at all, so I begin by providing a framework within which all these worries can be (...) seen as species of one genus: A claim of underdetermination involves (at least implicitly) a set of rival theories, a standard of responsible judgment, and a scope of circumstances in which responsible choice between the rivals is impossible. Within this framework, I show that one variety of underdetermination motivated modern scepticism and thus is a familiar problem at the heart of epistemology. I survey arguments that infer from underdetermination to some reëvaluation of science: top-down arguments infer a priori from the ubiquity of underdetermination to some conclusion about science; bottom-up arguments infer from specific instances of underdetermination, to the claim that underdetermination is widespread, and then to some conclusion about science. The top-down arguments either fail to deliver underdetermination of any great significance or (as with modern scepticism) deliver some well-worn epistemic concern. The bottom-up arguments must rely on cases. I consider several promising cases and find them to either be so specialized that they cannot underwrite conclusions about science in general or not be underdetermined at all. Neither top-down nor bottom-up arguments can motivate any deep reconsideration of science. (shrink)

In response to an impasse, articulated in the late 1980s, the cognitive capacities of ordinary people assumed central place in contemporary critical social theory. The participants’ perspective gained precedence over scientific standards branded as external. The notion of cognition, however, went unchallenged. This article continues the move away from external standards, and discusses two models of critique, which differ based on their underlying notions of cognition. The representational model builds on cognitive content, misrecognition and normativity; three features which are illustrated (...) with positions adopted by prominent exponents of critical social theory. An alternative understanding relies on action-oriented disclosure and the participants’ basic familiarity with the social world. On this reading, what clashes with unequal structures is skilful coping, rather than representations and normative standards. The action-oriented approach may overcome the dilemma of understanding both the impact and the possible transcendence of unequal structures, although it cannot ultimately replace representational critique.

This paper gives a characterization of distributed cognition (d-cog) and explores ways that the framework might be applied in studies of science. I argue that a system can only be given a d-cog description if it is thought of as performing a task. Turning our attention to science, we can try to give a global d-cog account of science or local d-cog accounts of particular scientific projects. Several accounts of science can be seen as global d-cog accounts: Robert Merton's sociology (...) of scientific norms, Philip Kitcher's 20th-century account of cognitive labor, and Kitcher's 21st-century notion of well-ordered science. Problems that arise for them arise just because of the way that they attribute a function to science. The paper concludes by considering local d-cog accounts. Here, too, the task is the crux of the matter. (shrink)

Krankheit und Verwundung gehörten in der Antike zum Alltag der Soldaten. Die militärische Fachschriftstellerei der Antike hat sich aus verschiedenen Blickwinkeln und mit unterschiedlichen Zielstellungen mit zahlreichen Aspekten des Militärwesens ihrer Zeit befasst. Der vorliegende Beitrag untersucht deshalb die Behandlung von Krankheit und Verwundung in den griechischen und römischen militärischen Fachschriften vom 4. Jh. v. Chr. bis ins 6. Jh. n. Chr. Aufgrund der spärlichen Forschungsliteratur zu diesem Thema steht die vergleichende Quellenanalyse der erhaltenen militärischen Fachschriften dieses Zeitraums im Vordergrund. (...) Ein kurzer Überblick über die literarische Gattung „Antike militärische Fachschriften“ sowie über die Entwicklung der Militärmedizin in der griechisch-römischen Antike bietet den nötigen Bezugsrahmen für die historische und literaturhistorische Einordnung der untersuchten Quellen. -/- Diseases and wounds were part of a soldier‘s everyday life in Greco-Roman antiquity. Ancient military manuals dealt with numerous aspects of contemporary military affairs from different perspectives and with various objectives. Therefore, this paper analyses how ancient Greek and Roman military manuals between the fourth century BC and the sixth century AD deal with diseases and wounds in the military. Due to scarce research literature on this topic the present paper focuses on the analysis of the surviving military manuals from this period. A brief overview of ancient military manuals as a literary genre as well as of the development of the ancient military medicine provides an historical and literary historical reference framework for the source analysis.

Metrisch gebundene Texte sind aus dem altsprachlichen Unterricht nicht wegzudenken: Vergil, Ovid, Horaz, Catull und Martial sind nur einige typische Autoren für die Dichtungslektüre im Lateinunterricht; Homer, Sophokles und Euripides sind typische Beispiele für den Griechischunterricht. Die Curricula schlagen eine Vielzahl poetischer Texte als mögliche Lektüren vor. Allein diese unvollständige Autorenauswahl zeigt schon, dass man allein mit der Behandlung von daktylischem Hexameter und elegischem Distichon nicht besonders weit kommt, will man nicht die Textauswahl nach solchen rein formalen Kriterien unnötig und (...) unzulässig einschränken oder bei allen anderen Metra so tun, als läse man Prosa. Denn ein solches Vorgehen ermöglicht zwar eine Übersetzung, ein wirkliches Verständnis der Texte bleibt den Schülern aber verwehrt, da ihnen die Wirkung des Metrums, der Einschnitte, der Betonung bestimmter Positionen im Vers und nicht zuletzt ästhetische Aspekte verborgen bleiben oder allenfalls indirekt durch den metrischen Vortrag des Lehrers oder eine stilistische Analyse erschlossen werden. -/- Der vorliegende Band widmet sich daher grundlegenden Fragen zum Thema lateinischer und griechischer Prosodie und Metrik im Unterricht unter Einbeziehung der Lehrpläne und einer Befragung von Lehrkräften.

The objective of this article is to see whether desire for recognition might contain an emancipatory aspect. Could this desire be a political ally? The argumentative strategy is to fully acknowledge the oppressive mechanisms at work before trying to find a way to other outcomes, including emancipation, with which desire for recognition has been associated in the tradition from Hegel. Through a re-interpretation of the master-and-slave dialectic, supplemented by sociological research on status expectations, I suggest a way out of the (...) vicious circle, where desire produced by power finds satisfaction through a preexisting other, resulting in an endless dynamic of compulsive conformity and regressive assertion of status. The hold of this dynamic must not be underestimated, yet, as I argue, both desire and what satisfies desire are liable to change, through struggle. The transformation of the generalized other, which provides recognition, is seen to be a crucial feature of all collective struggle. The very source of recognition is transformed, behind the backs of the actors, in turn affecting their desire. This can but must not lead to the emancipatory outcomes which are traditionally tied to recognition in the Hegelian tradition. (shrink)

Livro-texto de introdução à lógica, com (mais do que) pitadas de filosofia da lógica, produzido como uma versão revista e ampliada do livro Forallx: Calgary. Trata-se da versão de 13 de outubro de 2022. Comentários, críticas, correções e sugestões são muito bem-vindos.

Due to its concept and methodology, Graingers book on Frontinus is more fact-based fiction than biography. The reader gains an insight into how Frontinus' life and career might have unfolded, taking into account our knowledge of the Roman Empire in his time and the information about him that is confirmed by our sources. The author's assumptions are always plausibly substantiated. However, when reading the book, one learns far more about the Roman Empire, its provinces, its rulers and the political and (...) military conditions in the 1st century AD than about Frontinus. In this respect, this book is very exciting and informative, and it is also pleasant to read. (shrink)

In the Anabasis, his autobiographical account on the retreat of the Greek mercenary army after the defeat of the Persian prince Cyrus the Younger, Xenophon mentions a significant number of sacrifices. This paper deals with the analysis of the ritual, pragmatical, and narratological functions of these references as well as of their lexis and complexity. Therefore also a short overview of the role of sacrifices in the ancient Greek religion with a focus on military contexts is given.

In the Odyssey, there is a description of Odysseus being recognized by his age-old and decrepit dog Argos, whom he had reared and trained himself before his departure for Troy. This so-called Argos episode (Od. 17.290–327) is still famous today. It has been continuously treated by generations of scholars from antiquity to our time and served as an inspiration to both the visual arts and literature. The present article deals with the function and intended effects of the Argos scene. After (...) a brief synopsis of the position of this scene within the Odyssey as well as of its content and structure, the author discusses the role of dogs in the Iliad and the Odyssey. The focus of this article lies on the interpretations of the Argos scene, suggested by scholars so far, and on their review by means of a close reading to check their plausibility. (shrink)

Thomas Reid is often misread as defending common sense, if at all, only by relying on illicit premises about God or our natural faculties. On these theological or reliabilist misreadings, Reid makes common sense assertions where he cannot give arguments. This paper attempts to untangle Reid's defense of common sense by distinguishing four arguments: (a) the argument from madness, (b) the argument from natural faculties, (c) the argument from impotence, and (d) the argument from practical commitment. Of these, (a) and (...) (c) do rely on problematic premises that are no more secure than claims of common sense itself. Yet (b) and (d) do not. This conclusion can be established directly by considering the arguments informally, but one might still worry that there is an implicit premise in them. In order to address this concern, I reconstruct the arguments in the framework of subjective Bayesianism. The worry becomes this: Do the arguments rely on specific values for the prior probability of some premises? Reid's appeals to our prior cognitive and practical commitments do not. Rather than relying on specific probability assignments, they draw on things that are part of the Bayesian framework itself, such as the nature of observation and the connection between belief and action. Contra the theological or reliabilist readings, the defense of common sense does not require indefensible premises. (shrink)

The Prussian Protestant Daniel Hermann is an important Neo-Latin poet. He lived from probably 1543 until 1601. Hermann studied at Königsberg, Straßburg, Basel and Wittenberg. Afterwards he served as a secretary at the Imperial Court at Vienna, later as a secretary of the city of Danzig and permanent ambassador of Danzig at the Royal Polish court during the wars against Russia. After the war he married and settled down in Riga and became the secretary of the Polish governor Cardinal Radziwil (...) and later of the general Georg Fahrensbach. Besides lots of poems on academical, political and private occasions he wrote letters in poetic form as well as theological, philosophical and political poems. This paper provides an overview over Hermann ’s life and his poetry, especially the poems written and published in Riga, and a short summary of the research on this poet. (shrink)

Debates about the underdetermination of theory by data often turn on specific examples. Cases invoked often enough become familiar, even well worn. Since Helen Longino’s discussion of the case, the connection between prenatal hormone levels and gender-linked childhood behaviour has become one of these stock examples. However, as I argue here, the case is not genuinely underdetermined. We can easily imagine a possible experiment to decide the question. The fact that we would not perform this experiment is a moral, rather (...) than epistemic, point. Finally, I suggest that the ”underdetermination’ of the case may be inessential for Longino to establish her central claim about it. (shrink)

Eric Barnes’ The Paradox of Predictivism is concerned primarily with two facts: predictivism (the fact that novel predictions play an important part in scientificconfirmation) and pluralism (the fact that scientific development is not just a matter of isolated individuals judging the truth, but at least partly a matter of trusting legitimate experts). In the middle part of the book, he peers through these two lenses at the tired realist scarecrow of the no-miracles argument. He attempts to reanimate this weatherworn realist (...) argument, contra suggestions by people like me that it should be abandoned. In this paper, I want to get clear on Barnes’ contribution to the debate. He focuses on what he calls the miraculous endorsement argument, which explains not the success of a specific theory but instead the history of successes for an entire research program. The history of successes is explained by reliable and improving methods, which are the flipside of approximately true background theories. Yet, as Barnes notes, the whole story must begin with methods that are at least minimally reliable. Barnes demands that the realist explain the origin of the minimally reliable take-off point, and he suggests a way that the realist might do so. I contend that his explanation still relies on contingent developments and so fails to completely explain the development of take-off theories. However, this line of argument digs into familiar details of the no-miracles argument and overlooks what’s new in Barnes’ approach. By calling attention to pluralism, he reminds us that we need an account of scientific expertise. This is important, I suggest, because expertise is not indefinite. We do not trust specific experts for everything, but only for things within the bounds of their expertise. Drawing these boundaries relies on our own background theories and is only likely to be reliable if our background theories are approximately true. I argue, then, that pluralism gives us reason to be realists (about some things). (shrink)

The no-miracles argument and the pessimistic induction are arguably the main considerations for and against scientific realism. Recently these arguments have been accused of embodying a familiar, seductive fallacy. In each case, we are tricked by a base rate fallacy, one much-discussed in the psychological literature. In this paper we consider this accusation and use it as an explanation for why the two most prominent `wholesale' arguments in the literature seem irresolvable. Framed probabilistically, we can see very clearly why realists (...) and anti-realists have been talking past one another. We then formulate a dilemma for advocates of either argument, answer potential objections to our criticism, discuss what remains (if anything) of these two major arguments, and then speculate about a future philosophy of science freed from these two arguments. In so doing, we connect the point about base rates to the wholesale/retail distinction; we believe it hints at an answer of how to distinguish profitable from unprofitable realism debates. In short, we offer a probabilistic analysis of the feeling of ennui afflicting contemporary philosophy of science. (shrink)

In late 2014, the jazz combo Mostly Other People Do the Killing released Blue—an album that is a note-for-note remake of Miles Davis's 1959 landmark album Kind of Blue. This is a thought experiment made concrete, raising metaphysical puzzles familiar from discussion of indiscernible counterparts. It is an actual album, rather than merely a concept, and so poses the aesthetic puzzle of why one would ever actually listen to it.

There is considerable disagreement about the epistemic value of novel predictive success, i.e. when a scientist predicts an unexpected phenomenon, experiments are conducted, and the prediction proves to be accurate. We survey the field on this question, noting both fully articulated views such as weak and strong predictivism, and more nascent views, such as pluralist reasons for the instrumental value of prediction. By examining the various reasons offered for the value of prediction across a range of inferential contexts , we (...) can see that neither weak nor strong predictivism captures all of the reasons for valuing prediction available. A third path is presented, Pluralist Instrumental Predictivism; PIP for short. (shrink)

An introduction to sentential logic and first-order predicate logic with identity, logical systems that significantly influenced twentieth-century analytic philosophy. After working through the material in this book, a student should be able to understand most quantified expressions that arise in their philosophical reading. -/- This books treats symbolization, formal semantics, and proof theory for each language.

Students should realize that these two are not the only possible formal languages. In translating to a formal language, we simplify and profit in clarity. The simplification comes at a cost, and different formal languages are suited to translating different parts of natural language. (shrink)

A discussion and qualified defense of Philip Kitcher on scientific significance and ‘well-ordered science.’ (Qualified because I argue that Kitcher’s position is made unstable by his reliance on the largely unanalyzed notion of natural curiosity.).

There is a history of thinking that photographs provide a special kind of access to the objects depicted in them, beyond the access that would be provided by a painting or drawing. What is included in the photograph does not depend on the photographer’s beliefs about what is in front of the camera. This feature leads Kendall Walton to argue that photographs literally allow us to see the objects which appear in them. Current generative algorithms produce images in response to (...) users’ text prompts. Depending on the parameters, the output can resemble specific people or things which are named in the prompt. This resemblance does not depend on the user’s beliefs, so generated images are in this sense like photographs. Given this parallel, how should we think about AI-generated images? (shrink)

The Homeostatic Property Cluster (HPC) account of natural kinds has become popular since it was proposed by Richard Boyd in the late 1980s. Although it is often taken as a defining natural kinds as such, it is easy enough to see that something's being a natural kind is neither necessary nor sufficient for its being an HPC. This paper argues that it is better not to understand HPCs as defining what it is to be a natural kind but instead as (...) providing the ontological realization of (some) natural kinds. (shrink)

When someone does something for a reason, what are the reasons for which she does what she does? What is her ‘motivating reason’, as it is sometimes put? The simple answer is: it depends on what is meant by ‘motivating reason’. Non-Psychologists hold that motivating reasons are what the agent believes. I have shown that given that we understand ‘motivating reasons’ as what I term 'grounds', this is quite correct, as what we believe is what plays the role of a (...) ground. However, we have to be careful not to confuse the role of a ground and the role of an explanans. For the conflation of those two roles can occlude the truth in Non-Psychologism. What the Non-Psychologist about Grounds should say is that what plays the role of an explanans, when someone acts on a ground, is a motivation-fact. She should also say that there are two kinds of motivation-facts: those that include normative reasons and those that do not. (shrink)

Kyle Stanford has recently claimed to offer a new challenge to scientific realism. Taking his inspiration from the familiar Pessimistic Induction (PI), Stanford proposes a New Induction (NI). Contra Anjan Chakravartty’s suggestion that the NI is a ‘red herring’, I argue that it reveals something deep and important about science. The Problem of Unconceived Alternatives, which lies at the heart of the NI, yields a richer anti-realism than the PI. It explains why science falls short when it falls short, and (...) so it might figure in the most coherent account of scientific practice. However, this best account will be antirealist in some respects and about some theories. It will not be a sweeping antirealism about all or most of science. (shrink)

Homeostatic property clusters (HPCs) are offered as a way of understanding natural kinds, especially biological species. I review the HPC approach and then discuss an objection by Ereshefsky and Matthen, to the effect that an HPC qua cluster seems ill-fitted as a description of a polymorphic species. The standard response by champions of the HPC approach is to say that all members of a polymorphic species have things in common, namely dispositions or conditional properties. I argue that this response fails. (...) Instances of an HPC kind need not all be similar in their exhibited properties. Instead, HPCs should instead be understood as unified by the underlying causal mechanism that maintains them. The causal mechanism can both produce and explain some systematic differences between a kind’s members. An HPC kind is best understood not as a single cluster of properties maintained in stasis by causal forces, but as a complex of related property clusters kept in relation by an underlying causal process. This approach requires recognizing that taxonomic systems serve both explanatory and inductive purposes. (shrink)

There are two senses of ‘what scientists know’: An individual sense (the separate opinions of individual scientists) and a collective sense (the state of the discipline). The latter is what matters for policy and planning, but it is not something that can be directly observed or reported. A function can be defined to map individual judgments onto an aggregate judgment. I argue that such a function cannot effectively capture community opinion, especially in cases that matter to us.

The problem of underdetermination is thought to hold important lessons for philosophy of science. Yet, as Kyle Stanford has recently argued, typical treatments of it offer only restatements of familiar philosophical problems. Following suggestions in Duhem and Sklar, Stanford calls for a New Induction from the history of science. It will provide proof, he thinks, of “the kind of underdetermination that the history of science reveals to be a distinctive and genuine threat to even our best scientific theories” (Stanford 2001, (...) p. S12). This paper examines Stanford’s New Induction and argues that it – like the other forms of underdetermination that he criticizes – merely recapitulates familiar philosophical conundra. (shrink)

Abstract: There is a long tradition of trying to analyze art either by providing a definition (essentialism) or by tracing its contours as an indefinable, open concept (anti-essentialism). Both art essentialists and art anti-essentialists share an implicit assumption of art concept monism. This article argues that this assumption is a mistake. Species concept pluralism—a well-explored position in philosophy of biology—provides a model for art concept pluralism. The article explores the conditions under which concept pluralism is appropriate, and argues that they (...) obtain for art. Art concept pluralism allows us to recognize that different art concepts are useful for different purposes, and what has been feuding definitions can be seen as characterizations of specific art concepts.

According to the standard narrative, natural kind is a technical notion that was introduced by John Stuart Mill in the 1840s and the recent craze for natural kinds, launched by Putnam and Kripke, is a continuation of that tradition. I argue that the standard narrative is mistaken. The Millian tradition of kinds was not particularly influential in the 20th-century, and the Putnam-Kripke revolution did not clearly engage with even the remnants that were left of it. The presently active tradition of (...) natural kinds is less than half a century old. Recognizing this might help us better appreciate both Mill and natural kinds. (shrink)
