Contemporary physics, with two Einstein’s theories and with Heisenberg’s principle of indeterminacy are frequently interpreted as a removal of the causality from physics. We argue that this is wrong. There are no indications in physics, either classical or quantum, that physical laws are indeterministic, on the ontological level. On the other hand, both classical and quantum physics are, practically, indeterministic on the epistemic level: there are no means for us to predict the detailed future of the world. Additionally, essentially all (...) physical principles, including the arrow of time and the conservation of energy could be, hypothetically, violated. However, in contrast to Hume’s skepticism, we have no experimental evidence that the causality can be removed or even “hung on” in any case. The text contains some didactical-like issues, as well.

The speech act of inquiry is generally treated as a default kind of asking questions. The widespread norm states that one inquires whether p only if one does not know that p. However, the fact that inquiring is just one kind of asking questions has received little to no attention. Just as in the declarative mood we can perform not only assertions, but various other speech acts, like guesses or predictions, so in the interrogative mood we can also make various (...) speech act types. I propose a speech-act-theoretic account of a distinct kind of question that I label exam questions. According to the proposed account, one performs an exam question p only if (i) one has access to the answer to p, and (ii) one does not officially know whether the hearer knows the answer to p. Exam questions satisfy all the necessary requirements of being a distinct kind of speech act. Additionally, my proposal contributes to the recent expansion of the normative approach to a variety of speech acts. (shrink)

According to the normative approach, speech acts are governed by certain norms. Interestingly, the same is true for classes of speech acts. This paper considers the normative treatment of constatives, consisting of such classes as assertives, predictives, suggestives, and more. The classical approach is to treat these classes of illocutions as species of constatives. Recently, however, Simion (Shifty Speech and Independent Thought: Epistemic Normativity in Context, Oxford University Press, 2021) has proposed that all constatives (i) are species of assertion, and (...) (ii) are governed by the knowledge norm. I defend the classical treatment of constatives and show that Simion’s conclusion is untenable. No taxonomy of speech acts can accommodate such a view. More importantly, we can test whether a particular speech act is an assertion or not. I propose five tests of assertion, the passing of which is a necessary condition for being an assertion. Some constative speech acts fail these tests. Thus, contrary to Simion, not all constatives can be regarded as species of assertion. (shrink)

I propose an analysis of lying with uninformative speech acts. The orthodox view states that lying is restricted to assertions. However, the growing case for non-assertoric lies made by presuppositions or conventional implicatures challenges this orthodoxy. So far, the only presuppositions to have been considered as lies were informative presuppositions. In fact, uninformative lies were not discussed in the philosophical literature. However, limiting the possibility of lying to informative speech acts is too restrictive. Firstly, I show that standard, uninformative presuppositions (...) can also be lies. Secondly, I extend this picture into uninformative lies made by declarative statements. To implement my proposal, I do not need a new definition of lying. Recently popular commitment-based definitions of lying are able to properly handle uninformative lies. (shrink)

This paper offers a systematic classification and characterization of speech acts and their norms. Recently, the normative approach has been applied to various speech acts, most notably to constatives. I start by showing how the work on the norms of assertion has influenced various approaches to the norms of other speech acts. I focus on the fact that various norms of assertion have different extensions, i.e., they denote different clusters of illocutions as belonging to an assertion. I argue that this (...) has consequences for theorising about norms of other speech acts and generates certain arbitrary divisions. In the central part, I analyse two groups of speech acts. Firstly, ordinary speech acts, like predictions or retractions. Secondly, I indicate how the normative view can be extended to so-called ancillary speech acts, like presuppositions or implicatures. I end with a discussion of possible extensions of the normative approach, focusing on the debate on lying. (shrink)

The widely accepted view states that an intention to deceive is not necessary for lying. Proponents of this view, the so-called non-deceptionists, argue that lies are simply insincere assertions. We conducted three experimental studies with false explanations, the results of which put some pressure on non-deceptionist analyses. We present cases of explanations that one knows are false and compare them with analogical explanations that differ only in having a deceptive intention. The results show that lay people distinguish between such false (...) explanations and to a higher degree classify as lies those explanations that are made with the intention to deceive. Non-deceptionists fail to distinguish between such cases and wrongly classify both as lies. This novel empirical finding indicates the need for supplementing non-deceptionist definitions of lying, at least in some cases, with an additional condition, such as an intention to deceive.

I argue against Milić's (2017) proposal of analyzing “selfless assertions” (Lackey 2007) as proper, i.e., as assertions which satisfy the norm of assertion. In his view, selfless assertions are hedged assertions governed by the knowledge norm. In my critique, I show that Milić does not make a case that selfless assertions constitute such a special class of assertions. Moreover, he does not deliver a clear criterion for differentiating between flat-out assertions and hedged ones. What is more, his proposal leaves some (...) cases of selfless assertions unexplained. The outcome is that we are still left without a satisfactory account of selfless assertions as proper assertions. (shrink)

The following article begins with my recollection of the only academic conference on Zdziechowski that was organised still under the communist regime in the autumn of 1984 at the Jagiellonian University and ends with a description of the discussion on the genesis and power of evil, with the participation of Czesław Miłosz and Leszek Kołakowski, which was triggered in Poland immediately after the publication of the last edition of On Cruelty in 1993. On Cruelty was first published in 1928 in (...) the journal Przegla̧d Współczesny [Contemporary Review] in Krakow, a second time in 1938 in the volume of articles In the Face of the End, Krakow 1938, and a third – and so far last – time also in Krakow in 1993. On Cruelty, published three times but so far only in Polish, has never been thoroughly analysed or even discussed, which is why this article focuses on discussing it and related questions about the origins and nature of evil, mainly in Europe and Asia, from the earliest times to the present. Zdziechowski was particularly outraged when the cruelty he condemned was justified by religion, especially Christianity (Catholic and Protestant). From these condemnations, he described the activities of the Inquisition, the witch trials, cruelty to animals, and – in the introduction – the “psychology of cruelty.” At the same time, however, he meticulously listed the names of those political and spiritual leaders in Europe and Asia, theologians and thinkers, who, over many centuries, up to the present day, have resolutely spoken out against evil, including cruelty, within and outside the Church. A separate and important issue is Zdziechowski’s attitude to Tsarist Russia and Bolshevism, as outlined in his work On Cruelty. On the one hand, he pointed out that at least two rulers of Russia before 1917 – Ivan the Terrible and Peter the Great – had made major contributions to the history of cruelty in Europe and Asia. But Bolshevism, which Zdziechowski condemned in the strongest terms, was in his eyes not a continuation of pre-1917 Russian despotism, but emanated from the depths of Asia. (shrink)

This paper offers a normative account of the speech act of explanation with understanding as its norm. The previous accounts of the speech act of explanation rely on the factive notion of understanding and maintain that proper explanations require knowledge. I argue, however, that such accounts are too demanding and do not reflect the everyday practice of explanation and the attribution of understanding. Instead, I argue that the non-factive, objectual attitude of understanding is sufficient for a proper explanation. On the (...) normative level, explanations are governed by an audience-centred norm, i.e., they are sensitive to the epistemic position of the audience. According to the proposed account, an explanation is a communicative act in which one puts the audience in a position to understand the explained phenomenon. This proposal fits into the recent wave of applications of the normative account and makes space for the pluralism of illocutionary acts. (shrink)

Do the ethical features of an artwork bear on its aesthetic value? This movie endorses misogyny, that song is a civil rights anthem, the clay constituting this statue was extracted with underpaid labor—are facts like these the proper bases for aesthetic evaluation? I argue that this debate has suffered from a false presupposition: that if the answer is yes (for at least some such ethical features), such considerations feature as pro tanto contributions to an artwork's overall aesthetic value, i.e., as (...) merits or flaws which make something have more or less overall aesthetic value. As the case of ethically laden, aesthetic evaluation makes clear, however, good aesthetic judgement is irreducibly multi-dimensional, e.g., "the movie has an engaging soundtrack, tasteful camera work, and takes a misogynistically prurient perspective on its female lead.'' Such a "non-summative" judgement refuses to reduce those various dimensions of aesthetic value to a single aggregate aesthetic evaluation, like "it's a 6/10" or "it's a pretty good movie!" I defend both the modest claim that such non-summative evaluations are not mistaken and the extremist claim that summative (i.e., unidimensional) aesthetic evaluation is defective by considering other domains of normative assessment in which summing seems inappropriate, notably including evaluations of people's character.

The monograph contains three works on research on the concept of a rejected sentence. This research, conducted under the supervision of Prof. Jerzy Słupecki by U. Wybraniec-Skardowska (1) "Theory of rejected sentences" and G. Bryll (2) "Some supplements of theory of rejected sentences" and (3) "Logical relations between sentences of empirical sciences" led to the construction of a theory rejected sentences and made it possible to formalize certain issues in the methodology of empirical sciences. The concept of a rejected sentence (...) was introduced by J. Łukasiewicz in the course of his inquiry into Aristotelian Syllogistic. It was essentialy generelized by J. Słupecki who, with reference to Tarski's axiomatic theory of deductive systems (1930), gave the formal definition of the rejection function Cn' according to which a sentence y is rejected on the base of a set of sentences X iff at least one sentence which belongs to X can be deduced from the sentence y. Słupecki proved (1959) that the function Cn', which assignes to the set X the set of sentences rejected on the basis of X, is additive and satisfies the axioms of Tarski's general theory of deductive systems. Work (1) uses not only Tarski's general theory of systems but also his the so-called enlarged theory of systems (1930). It constructs a theory T of rejected sentences (propositions), which is created from Tarski's richer theory of systems by adding one axiom and a number of definitions; among them the definition of the rejection function Cn' is fundamental one. Cn' is a function which assignes to every set X of false sentences the set Cn'X whose members are exclusively false senteces. A number of theorems which describes properties of defined concepts have been proved in T. Some of them are necessary for conducting considertions of the concluding section of (1) devoted to the empirical sentences. Section 2 of (1) deals with the theory of the unit consequenses. It is characterized by an axiom from which follow all axioms of Tarski's general theory of deductive systems, additivity and the property that the unit consequence of the set X of sentences is a unit consequence only one sentence of X. An example of unit consequence is the rejection consequence Cn'. In section 3 of (1) the dual theory T' equivalent to T is presented. In T' the primitive concept is the rejection function Cn'. The fundamental axiom of T' states that Cn' is a unit consequence. The concluding section brings a few examples of applications of the definitions and theorems of T in the domain of the scientific methodology. Work (2) corresonds to J. Słupecki paper (1959) and the theory T of rejected propositions given in work (1). In this paper some suplements of the theory T are given. Work (3) is an extension of the theory of rejected propositios given in the paper (1). It is an attempt of formalization some problems of methodology of the empirical sciences which concern to such concepts as: empirical sentence, similar sentence, generalization, inductive conclusion etc. (shrink)

In this paper, I show that Turri’s (2015a) experimental study concerning selfless assertions is defective and should therefore be rejected. One performs a selfless assertion when one states something that one does not believe, and hence does not know, despite possessing well supported evidence to the contrary. Following his experimental study, Turri argues that agents in fact both believe and know the content of their selfless assertions. In response to this claim, I demonstrate that the conclusions he draws are premature (...) in this regard. More specifically, I criticize his methodology, showing that his study is not only incomplete but also yields contradictory results. In closing, I propose how such a study should be conducted in order to receive comprehensive results. (shrink)

The paper remains and reinforces a viewpoint that science and religion (theology) are methodologically and epistemologically independent. However, it also suggests that this independence can be overcome if a "third party" is taken into account, that is - philosophy. Such possibility seems to follow from the thesis of incommensurability and the thesis of underdetermination formulated and analyzed in current philosophy of science.

The notion of so-called "postulated ontology" appears in the context of a well- -known thesis of the underdetermination of scientific theories by empirical data. It is argued in the paper, that the conviction of the existence of some kind of relation between a given theory and ontological ideas can be derived from this thesis, regardless of its particular form. Therefore, certain solutions to classical philosophical questions can be obtained, in principle, by careful inspection of scientific achievements. However, if the thesis (...) of underdetermination holds, such philosophical solutions are not imposed by science itself. In order to arrive at some kind of ontology based on science, it seems necessary to accept certain philosophical presuppositions in the first place. This, and the fact that scientific theories change in time show that although such a kind of ontology is possible, and perhaps desirable, it can never be ultimate. (shrink)

The notion of chance plays an important role in some philosophical analyses and interpretations of scientific theories. The most obvious examples of that are the theories of evolution and quantum mechanics. This notion, however seems to be notoriously vague. Its application in such analyses, more often than not refers to its common-sense understanding, which, by definition, cannot be sufficient when it comes to sound philosophical interpretations of scientific achievements. The paper attempts at formulating a ‘typology of chance’. It distinguishes eight (...) different meanings of this notion. Those meanings can be found in classical philosophical accounts of chance, in the common usage of this term, or form logical possibilities of its understanding. Subsequently, the paper points to those forms of the notion in question which may and may not be properly applied to scientific theories and ideas – given usual characteristics of natural sciences. It also shows – by the examples of particular theories mentioned above – which of the distinguished forms of the notion of chance are actually applicable in the context of these theories. (shrink)

Tendencja do zmniejszenia kosztów produkcji przez firmy działające na międzynarodowym rynku dotyka również reklamy. Międzynarodowe przedsiębiorstwa, chcąc ograniczyć wydatki na reklamę w poszczególnych krajach, decydują się coraz częściej na stosowanie tej samej reklamy w mniej lub bardziej zmienionej formie w różnych krajach, nie bacząc przy tym na istniejące między tymi krajami różnice kulturowe. Prezentowany artykuł wykazał, że istnieje wiele czynników, które należy uwzględnić w reklamie międzynarodowej, a których znajomość pozwala na podwyższenie jej efektywności w istotny sposób. Różnice między reklamą narodową (...) a międzynarodową dotyczą przede wszystkim czynników politycznych, gospodarczych i socjalnych, które wytyczają normy prawne, wpływają na wybór odpowiedniej strategii reklamy oraz wskazują na sposób zachowania konsumentów. Istotny wpływ na sukces reklamy międzynarodowej ma również dostrzeżenie różnic w nastawieniu do reklamy i jej postrzeganiu przez poszczególne społeczeństwa, wynikające z przynależności do innych kręgów kulturowych, które determinują myślenie i zachowanie jednostek. Każda kultura wykształciła swój własny system wartości i przywiązuje różną wagę do emocji. Mimo używania tych samych środków komunikacji w formie języka i obrazu znaki werbalne i wizualne jednej kultury nie zawsze mają swe wierne odpowiedniki w innej kulturze, mogą bowiem różnić się między sobą wywoływanymi skojarzeniami i konotacjami. Reklama międzynarodowa może być skuteczna we wszystkich krajach jedynie wtedy, jeśli uwzględni wspomniane różnice między poszczególnymi kulturami i dostosuje się na ich podstawie do specyfiki każdego rynku zbytu. Najlepszym rozwiązaniem dla reklamy międzynarodowej jest tym samym dążenie do maksymalnej standardyzacji reklamy przy jednoczesnym uwzględnieniu niezbędnych dyferencji kulturowych. (shrink)

Reklama jako sztuka perswazji wykorzystuje obecnie każdą technikę i każdy środek w celu zwiększenia swego wpływu na potencjalnego konsumenta. Ważnym aspektem reklamy są tzw. słowa-klucze (Schlüsselwörter), które ze względu na swą semantykę wywołują różnorodne pozytywne konotacje i skojarzenia. Słowa te transportują pewne wartości, które zostają przez konsumenta przenoszone na reklamowany produkt, co przyczynia się do zwiększenia wartości danego produktu w oczach konsumenta. Analizie poddano 100 tekstów reklamowych, które ukazały się w prasie niemieckiej w latach 2001-2002. Słowa-klucze zostały wyodrębniane osobno z (...) czterech grup tekstów reklamowych w zależności od reklamowanego produktu: leki, biżuteria, kosmetyki, samochody. W prezentowanym artykule wykazano, że użycie słów-kluczy zależy od reklamowanego produktu, co związane jest z reprezentowanymi przez te słowa różnymi wartościami i wywoływanymi przez nie różnymi konotacjami i skojarzeniami. W reklamie leków największą rolę odgrywają takie wartości jak skuteczność i naturalność, które spełniają w pełni oczekiwania konsumenta co do stosowania reklamowanych leków. Reklamy biżuterii podkreślają trwałość, tradycję i kosztowność produktów, dzięki czemu odnoszą się do emocji konsumentów i podkreślają ich status społeczny. Reklama samochodów kieruje uwagę konsumenta na bezpieczeństwo, technikę i komfort reklamowanych pojazdów, co podkreśla dostosowanie się do głównych potrzeb kupującego. Reklamy kosmetyków zachwalają natomiast swe produkty takimi określeniami, jak pielęgnacja, efektywność i skuteczność. Wspomniane słowa-klucze wskazują bezpośrednio lub poprzez skojarzenia i konotacje różne wartości, które odgrywają istotną rolę w danym społeczeństwie. Poprzez podświadome przeniesienie tych wartości na reklamowany produkt potencjalny konsument nie dokonuje zakupu określonego produktu, lecz postrzega ten produkt przez pryzmat związanych w nim wartości i decyduje się na kupno, jeśli dane wartości spełniają jego potrzeby. W wyniku powyższych rozważań można stwierdzić, iż konsument nie kupuje jedynie materialnego produktu, który dla konsumenta tylko w nieistotny sposób różni się od innych produktów tego samego rodzaju, ale wartości przekazywane przez reklamę pod postacią słów-kluczy.

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.

In their insightful article, Brent Kious and Margaret Battin (2019) correctly identify an inconsistency between an involuntary psychiatric commitment for suicide prevention and physician aid in dying (PAD). They declare that it may be possible to resolve the problem by articulating “objective standards for evaluating the severity of others’ suffering,” but ultimately they admit that this task is beyond the scope of their article since the solution depends on “a deep and difficult” question about comparing the worseness of two possible (...) scenarios: letting someone die (who could have been helped) with not letting someone die (whose suffering could only be alleviated by death). In our commentary, we argue that creating such standards is more difficult than the authors assume because of the many types of deep uncertainties we have to deal with: (1) diagnostic, (2) motivational, and (3) existential.

While agreeing with the main conclusion of Dominic Wilkinson and colleagues (Wilkinson, Butcherine, and Savulescu 2019), namely, that there is no moral difference between treatment withholding and withdrawal as such, we wish to criticize their approach on the basis that it treats the widespread acceptance of withdrawal aversion (WA) as a cognitive bias. Wilkinson and colleagues understand WA as “a nonrational preference for withholding (WH) treatment over withdrawal (WD) of treatment” (22). They treat WA as a manifestation of loss aversion (...) and refer to Kahneman and colleagues (1991), which defined this effect as follows: “the disutility of giving up an object is greater that the utility associated with acquiring it” (194). In a previous work, Wilkinson and Savulescu understood nonequivalence between treatment withholding and withdrawal as a reflection of slightly different, although related, phenomena: status quo bias or omission bias (Wilkinson and Savulescu 2012, 130–131). In neither of these two papers do they describe precisely the relation between these well-known psychological effects and WA, nor do they explain why they treat these effects as examples of nonrational preferences, despite the fact that these issues have been the subject of wide-ranging discussions on the intersection of psychology, economy, and philosophy.

In this chapter we explore two important questions that we believe should be central to any discussion of the ethics and politics of cultural heritage: What are the harms associated with appropriation and commodification, specifically where the heritage of Indigenous peoples is concerned? And how can these harms best be avoided? Archaeological concerns animate this discussion; we are ultimately concerned with fostering postcolonial archaeological practices. But we situate these questions in a broader context, addressing them as they arise in connection (...) with the appropriation of Indigenous cultural heritage, both past and present. (shrink)

Science and valuation — remarks about the condition of philosophical re ection on science this text is an attempt at a more general look at twentieth‐century philosophical re ection on science conceived as persistent trials to eliminate the non‐eliminateable, i.e. valuations. In this article, I recall the most important concepts of knowledge developed in the twentieth‐century philosophy of science by exposing assumed axiology in, among other things: the Vienna Circle, Karl raimund Popper’s falsi cationism, the historical and social approach of (...) thomas S. Kuhn’s paradigm, and the concept of the ideals of knowledge by Stefan Amsterdamski. I argue that the axiology, and more broadly philosophy is an indelible com‐ ponent of each accepted concept of scienti c knowledge. each concept of knowledge assumes a form of its valuation.

Sociology, as conceived by Comte, was to put an end to the anarchy of opinions characteristic of liberal democracy by replacing opinion with the truths of sociology, imposed through indoctrination. Later sociologists backed away from this, making sociology acceptable to liberal democracy by being politically neutral. The critics of this solution asked 'whose side are we on?' Burawoy provides a novel justification for advocacy scholarship in sociology. Public sociology is intended to have political effects, but also to be funded by (...) the politically neutral state. He argues that public sociology is institutionally neutral, but that committing to an organic relation with a social movement is legitimate as a matter of the sociologist's personal value choice. Although this produces side-taking sociology, by improving the case for particular standpoints it serves to improve democratic discussion generally, which is an appropriately neutral public aim.

Heated debates stemming from the confrontation of scientific knowledge with the biblical picture of the creation of man, which had followed the publication of Darwin's theory of evolution, became far less prominent in the second half of the 20th century. This was due to two factors: first, the theory of evolution was partly accepted in theological circles and at the same time biologists showed a growing awareness of the limited epistemological scope of the competence of the natural sciences. This lesson (...) from the history, however, seems to have been forgotten by many who now and again return to controversies which more often than not are caused by ideological quarrels over religion, with true scholarship being too easily lost from sight. The paper reminds some of the history of the controversy in question and suggests that at least some of the current problems regarding evolution˗and˗ creation controversy may have already found their solutions. In part 1, “The Theory of Evolution and the Creation of the Human” it deals with the general issue of human origins. In part 2, “Monogenism and Original Sin” it explores the notion of the ‘first human’ as it is employed in biology and in theology, and shows its completely different meaning in these two realms of knowledge which helps to resolve the recurrent controversy over monogenism.

Introduction: The Faculty of Medicine, University of Moratuwa, established during the COVID-19 pandemic, was compelled to conduct the teaching activities online for the first intake of students until their first bar examination. Online learning is known to be linked to several health issues. This study aims to explore the academic performance and perceived health effects related to online learning in the Faculty of Medicine, Moratuwa. Methods: A descriptive cross-sectional study was conducted among all 104 first-intake students using an anonymous online (...) self-administered questionnaire to explore health effects and academic performance after ethical clearance. Results: Out of 104 students, 82 students responded (response rate=78.85%). Majority participated from home using their own laptop (74.4%) and personal Wi-Fi (69.5%) and spent 5-10 hours daily for online academic activities (72%). Majority complained of related physical (86.6%), and psychological (81.7%) health issues: eye problems (69.5%), headache (47.6%), backache (43.9%), stress (46.3%) and concentration difficulties (45.1%). The first bar examination was cleared by 84.1% with the majority (52.4%) obtaining classes. There was a statistically significant positive association (p< .05) between physical and psychological health concerns with the average screen-time spent on academic activities, but not with the academic performance. There was also no statistically significant association between screen-time and academic performance. Conclusions: Majority of students using online learning had related physical and psychological health issues which were positively associated with the screen-time though not with academic performance. Designing online activities with less screen time may be considered as a strategy to minimise health effects related to online learning. (shrink)

This is a transcript of a conversation between P F Strawson and Gareth Evans in 1973, filmed for The Open University. Under the title 'Truth', Strawson and Evans discuss the question as to whether the distinction between genuinely fact-stating uses of language and other uses can be grounded on a theory of truth, especially a 'thin' notion of truth in the tradition of F P Ramsey.

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.

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)

Imperatives cannot be true, but they can be obeyed or binding: `Surrender!' is obeyed if you surrender and is binding if you have a reason to surrender. A pure declarative argument — whose premisses and conclusion are declaratives — is valid exactly if, necessarily, its conclusion is true if the conjunction of its premisses is true; similarly, I suggest, a pure imperative argument — whose premisses and conclusion are imperatives — is obedience-valid (alternatively: bindingness-valid) exactly if, necessarily, its conclusion is (...) obeyed (alternatively: binding) if the conjunction of its premisses is. I argue that there are two kinds of bindingness, and that a vacillation between two corresponding variants of bindingness-validity largely explains conflicting intuitions concerning the validity of some pure imperative arguments. I prove that for each of those two variants of bindingness-validity there is an equivalent variant of obedience-validity. Finally, I address alternative accounts of pure imperative inference.

Philosophy in Africa has for more than a decade now been dominated by the discussion of one compound question, namely, is there an African philosophy, and if there is, what is it? The first part of the question has generally been unhesitatingly answered in the affirmative. Dispute has been primarily over the second part of the question as various specimens of African philosophy presented do not seem to pass muster. Those of us who refuse to accept certain specimens as philosophy (...) have generally been rather illogically said also to deny an affirmative answer to the first part of the question. In a paper presented at the International Symposium in Memory of Dr William Amo, the Ghanaian philosopher who taught in German universities in the early part of the eighteenth century, Professor Odera Oruka identified four trends, perhaps more appropriately approaches, in current African philosophy.

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)

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)

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)

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)

Some philosophers understand natural kinds to be the categories which are constraints on enquiry. In order to elaborate the metaphysics appropriate to such an account, I consider the complicated history of scurvy, citrus, and vitamin C. It may be tempting to understand these categories in a shallow way (as mere property clusters) or in a deep way (as fundamental properties). Neither approach is adequate, and the case instead calls for middle-range ontology: starting from categories which we identify in the world (...) and elaborating their structure, but not pretending to jump ahead to a complete story about fundamental being.

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)

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)
