1 Context The idea for the current issue of _Philosophia Scientiæ_ emerged from discussions which took place in the Manchester Ethnomethodology Reading Group. This reading group has its origins in Wes Sharrock’s weekly discussion groups, which have taken place in Manchester (UK) since the early 1970s. As the global Covid-19 pandemic hit in early 2020, the reading group moved online, facilitated by Phil Hutchinson and Alex Holder. Being an online reading group opened up participation to people beyond Northwest (...) UK and within weeks the group became global, with the membership including participants logging on from Canada, Czech Republic, Finland, France, Germany, Greece, Hong Kong, Japan, Macau, New Zealand, Spain, Sweden, and the USA. While the name of the group might indicate an exclusive focus on ethnomethodology, following the naming conventions for academic discussion groups, the name really fails to indicate both the heterogeneity of the group’s reading materials, the interests of t...

Bioethics seems preoccupied with establishing, debating, promoting and sometimes debunking principles. While these tasks trade on the status of the word ‘principle’ in our ordinary language, scant attention is paid to the way principles operate in language. In this paper, we explore how principles relate to rules and practices so as to better understand their logic. We argue that principles gain their sense and power from the practices which give them sense. While general principles can be, and are, establishable in (...) abstraction from specific practices, as they are in principlist bioethics, such principles are impotent as moral guides to action. We show that the purchase any principle has as a moral guide to action emerges from its indexical properties as a principle which has sense in a specific practice. The meaning of any principle is internal to the practice and context in which it is invoked and, therefore, principles are not kinds of master rule which dictate moral judgement in new contexts but rather chameleon-like rules which change with the contexture in which they are invoked.

In this paper I focus on four varieties of shame absence. My hope is that re-flection on these varieties of shame-absence will go some way to giving us a more complete picture of the role that shame plays in our moral character and in discussions of atrocity. I note that the shame that emerges from an exposure to atrocity can be in part what leads us to identify the event as atro-cious. I progress to argue that when shame is absent, (...) this absence can serve to blind us to the atrocity that is before us and that is ours to work to prevent. Feeling shame is part of seeing the atrocity for what it is in an appropriate emotionally-engaged manner. It is thus a vital part of being human, and its absence in certain cases is an all-too-human failure of humanity. (shrink)

Philosophical debates about how best to explain emotion or placebo are debates about how best to characterise and explain the distinctive form of human responsiveness to the world that is the object of interest for each of those domains of inquiry. In emotion research, the cognitive theory of emotion faces several intractable problems. I discuss two of these: the problem of epistemic deficit and the problem of recalcitrant emotions. Cognitive explanations in Placebo Studies, such as response-expectancy and belief-based explanations, also (...) face the problem of epistemic deficit in addition to the problem of logically self-destructive true belief. While such considerations might motivate a retreat to affect, this brings its own problems. I argue that it is a particular version of cognitivism, representational cognitivism (Rep-Cog), that generates the paradoxes we encounter in emotion and placebo research. I propose that turning to nonrepresentational accounts of cognition will dissolve these paradoxes. As I move toward conclusion, I propose drawing on the ethnomethodological tradition to respecify human responsiveness to loci of significance in the lifeworld by undertaking ethnographies of members’ own situated methods for making intelligible and accountable their attitudinal and nonattitudinal responsiveness to loci of significance in their environment.

Since its origins in the mid-Twentieth Century, Cognitive Science has almost exclusively operated within the philosophical frames provided by Cartesian Representationalism. In recent years, alternative, phenomenological and pragmatist, frames have served as a resource for the emergence of non-representational approaches to mind and cognition. These have been gathered under the label ‘4E cognition’, indicating their Embodied, Extended, Enacted and Embedded nature. This chapter examines one version of 4E cognition, which builds upon Ecological Psychology, and argues that it fails to pass (...) the Evaluation Test: it cannot account for the central role of normativity and evaluation in our responsiveness to loci of significance in the lifeworld, while failing to provide an argument for the exclusion of evaluative and normative aspects.

Is there a response, which is not accounted for by regression to the mean, natural history, the Hawthorne effect?The term placebo comes to us from the Latin for "I shall please," indicating that the phenomenon known as the "placebo effect" or "placebo response" has been familiar to medical practitioners for a number of centuries, at least. As we reached the mid-20th century and randomized controlled trials became a central feature of medical research, the use of controls and blinding in those (...) trials allowed for the isolation of the placebo effect in ways that made it much clearer that there...

The death of Peter Winch in 1997 sparked a revived interest in his work with this book arguing his work suffered misrepresentation in both recent literature and in contemporary critiques of his writing. Debates in philosophy and sociology about foundational questions of social ontology and methodology often claim to have adequately incorporated and moved beyond Winch's concerns. Re-establishing a Winchian voice, the authors examine how such contentions involve a failure to understand central themes in Winch's writings and that the issues (...) which occupied him in his Idea of a Social Science and its Relation to Philosophy and later papers remain central to social studies. The volume offers a careful reading of the text in alliance with Wittgensteinian insights and alongside a focus on the nature and results of social thought and inquiry. It draws parallels with other movements in the social studies, notably ethnomethodology, to demonstrate how Winch's central claim is both more significant and more difficult to transcend than sociologists and philosophers have hitherto imagined.

In this article I examine three ways in which one might interpret Wittgenstein's Philosophical Investigations (PI). In a partial response to Hans‐Johann Glock's article in this journal, I suggest that since publication PI has, broadly speaking, been interpreted in three ways: doctrinal; elucidatory; or therapeutic. The doctrinal interpretation is shown to be, at best, difficult to sustain textually. The elucidatory (standard) interpretation, though seemingly closer to the text, is shown both to implicate Wittgenstein in some unfortunate philosophical commitments and to (...) face a problem of “motivation.” I argue that, correctly understood, any attempt to elucidate in PI is undertaken only in pursuit of the therapeutic goal. I conclude by arguing that the therapeutic interpretation is the only interpretation that can adequately make sense of Wittgenstein's text as a whole and the metaphilosophical remarks in particular. Furthermore, it is the only interpretation that can demonstrate Wittgenstein's continued importance and relevance as a philosopher. (shrink)

Gordon Baker in his last decade published a series of papers (now collected in Baker 2004), which are revolutionary in their proposals for understanding of later Wittgenstein. Taking our lead from the first of those papers, on "perspicuous presentations," we offer new criticisms of 'elucidatory' readers of later Wittgenstein, such as Peter Hacker: we argue that their readings fail to connect with the radically therapeutic intent of the 'perspicuous presentation' concept, as an achievement-term, rather than a kind of 'objective' mapping (...) of a 'conceptual landscape.' Baker's Wittgenstein, far from being a 'language policeman' of the kind that often fails to influence mainstream philosophy, offers an alternative to the latent scientism of Wittgenstein's influential 'elucidatory' readers.

In this paper we introduce Critical Praxeological Analysis (CPA). CPA respecifies critical studies and research by operationalising insights from gestalt psychology and, in particular, the praxeological and linguistic gestalts identified by Harold Garfinkel and Ludwig Wittgenstein. CPA offers a framework for analysing the in-situ production, maintenance, challenging, repair and overcoming of norms and structures. Using naturally occurring data, as well as fictional and imagined examples, CPA examines the meanings that situations have for the participants who constitute them. The paper provides (...) brief praxeological analyses, which draw upon themes from Frantz Fanon’s work to illustrate CPA in practice. We conclude by inviting others to apply CPA to themes drawn from the critical studies literature, in the hope that such analyses will deepen our understanding of how norms and structures are produced, maintained, challenged, repaired and overcome in interaction.

Much has been written on the relative merits of different readings of Wittgenstein's Tractatus Logico-Philosophicus. The recent renewal of the debate has almost exclusively been concerned with variants of the ineffabilist (metaphysical) reading of TL-P - notable such readings have been advanced by Elizabeth Anscombe, P. M. S. Hacker and H. O. Mounce - and the recently advanced variants of therapeutic (resolute) readings - notable advocates of which are James Conant, Cora Diamond, Juliet Floyd and Michael Kremer. During this debate, (...) there have been a number of writers who have tried to develop a third way, incorporating what they see as insights and avoiding what they see as flaws in both the ineffabilist and resolute readings. The most prominent advocates of these elucidatory readings of TL-P are Dan Hutto (2003) and Marie McGinn (1999). In this paper we subject Hutto's and McGinn's readings of TL-P to critical scrutiny. We find that in seeking to occupy the middle ground they ultimately find themselves committed to (and in the process commit Wittgenstein to) the very ineffabilism they (and Wittgenstein) are seeking to overcome.

In this paper, we explicate the method of Investigative Ordinary Language Philosophy (IOLP). The term was coined by John Cook to describe the unique philosophical approach of Frank Ebersole. We argue that (i) IOLP is an overlooked yet valuable philosophical method grounded in our everyday experiences and concerns; and (ii) as such, Frank Ebersole is an important but neglected figure in the history of ordinary language philosophy.

Throughout his career, Wes Sharrock has, following in the footsteps of Ludwig Wittgenstein, Peter Winch and Harold Garfinkel, sought to argue against accounts of the identity of an action which are the products of a social theory, a specific methodology or what Garfinkel termed formal analysis. In contrast, much of contemporary social science and social theory is grounded in a belief that ordinary or competent members of societies are unreliable authorities on the identity of their own and others’ actions because (...) they are subject to systems of sociological refraction. The idea being that ordinary members of society are systematically misled as to the identity of their actions and those of their peers because they—or their perceptions of actions—are subject to the refractive properties of (for example) ideology, or folk theories of action, and so on. In this paper, I subject to analysis this core commitment of much social science and social theory. (shrink)

In this paper, I discuss stigma, understood as a category which includes acknowledged, enacted degradation, discreditation and discrimination. My discussion begins with an analysis of HIV stigma, as discussed in a social media post on Twitter. I then analyse a fictionalized clinical stigma scenario. These two analyses are undertaken to highlight aspects of the conceptual anatomy and interactional dynamics of stigma and by extension shame. Brief social media declarations and short, fictionalized clinical interactions are rich with information which helps us (...) understand how stigma—degradation, discreditation and discrimination—is operationalized in interaction.

In our article, Where the ethical action is, we argue that medical and ethical modes of thought are not different in kind but merely different aspects of a clinical situation. In response, Emmerich argues that in so doing, we neglect several important features of healthcare and medical education. Although we applaud the spirit of Emmerich’s response, we argue that his critique is an attempt at a general defence of the value of bioethical expertise in clinical practice, rather than a specific (...) critique of our account. (shrink)

It is common to think of medical and ethical modes of thought as different in kind. In such terms, some clinical situations are made more complicated by an additional ethical component. Against this picture, we propose that medical and ethical modes of thought are not different in kind, but merely different aspects of what it means to be human. We further propose that clinicians are uniquely positioned to synthesise these two aspects without prior knowledge of philosophical ethics.

InWhere the Ethical Action Is,we argued that medical and ethical modes of thought are not different in kind but different aspects of a situation. One of the consequences of this argument is that the requirement for or benefits of normative moral theorising in bioethics is undercut. In response, Wagner has argued that normative moral theories should be reconceived as models. Wagner’s argument seems to be that once reconceived as models, the rationale for moral theorising, undercut by our arguments inWhere the (...) Ethical Action Is,will be re-established because we will see those moral-theories-now-rebranded-as-models as serving a role akin to the role models serve in some of the natural sciences. In this response to Wagner, we provide two arguments against Wagner’s proposal. We call these arguments the Turner-Cicourel Challenge and the Question Begging Challenge. (shrink)

Frege claims that the laws of logic are characterized by their “generality,” but it is hard to see how this could identify a special feature of those laws. I argue that we must understand this talk of generality in normative terms, but that what Frege says provides a normative demarcation of the logical laws only once we connect it with his thinking about truth and science. He means to be identifying the laws of logic as those that appear in every (...) one of the scientific systems whose construction is the ultimate aim of science, and in which all truths have a place. Though an account of logic in terms of scientific systems might seem hopelessly antiquated, I argue that it is not: a basically Fregean account of the nature of logic still looks quite promising.

This paper focuses on the novel and leading innovations and investments into the new energy technologies. Energy issues, including sustainability, energy security and energy dependency are probably one of the most crucial and critical issues that humanity must face at the moment. Recent global challenges, such as climate change and the rise of the “green” energy (represented by the increasing deployment of the renewable energy sources (RES)), as well as distributed energy generation and platform energy markets (e.g. peer-to-peer (P2P) markets (...) for electricity) that were made possible thanks to the rise of Internet, social networks and sharing economy, all create a demand for the new energy technologies. The leaders in energy innovations, such as Tesla are becoming the true trendsetters who are marking the way for the humankind to go forward.We provide an overview of the innovative energy technologies that might change the energy market as we know it and discuss their outcomes and possible implications. Moreover, we contemplate the changes that might be caused by the ongoing transition from the fossil fuels to RES. Our results might be of some interests to researchers and stakeholders dealing with energy economics and policy. (shrink)

Commentators regularly attribute to Frege realist, idealist, and quietist responses to metaphysical questions concerning the abstract objects he calls ‘thoughts’. But despite decades of effort, the evidence offered on behalf of these attributions remains unconvincing. I argue that Frege deliberately avoids commitment to any of these positions, as part of a metaphysical separatist policy motivated by the fact that logic is epistemologically autonomous from metaphysics. Frege’s views and arguments prove relevant to current attempts to argue for epistemological autonomy, particularly that (...) of ethics. (shrink)

Aristotle holds that individual substances are ontologically independent from nonsubstances and universal substances but that non-substances and universal substances are ontologically dependent on substances. There is then an asymmetry between individual substances and other kinds of beings with respect to ontological dependence. Under what could plausibly be called the standard interpretation, the ontological independence ascribed to individual substances and denied of non-substances and universal substances is a capacity for independent existence. There is, however, a tension between this interpretation and the (...) asymmetry between individual substances and the other kinds of entities with respect to ontological independence. I will propose an alternative interpretation: to weaken the relevant notion of ontological independence from a capacity for independent existence to the independent possession of a certain ontological status.

Although arguments for and against competing theories of vagueness often appeal to claims about the use of vague predicates by ordinary speakers, such claims are rarely tested. An exception is Bonini et al. (1999), who report empirical results on the use of vague predicates by Italian speakers, and take the results to count in favor of epistemicism. Yet several methodological difficulties mar their experiments; we outline these problems and devise revised experiments that do not show the same results. We then (...) describe three additional empirical studies that investigate further claims in the literature on vagueness: the hypothesis that speakers confuse ‘P’ with ‘definitely P’, the relative persuasiveness of different formulations of the inductive premise of the Sorites, and the interaction of vague predicates with three different forms of negation.

Despite much discussion over the existence of moral facts, metaethicists have largely ignored the related question of their possibility. This paper addresses the issue from the moral error theorist’s perspective, and shows how the arguments that error theorists have produced against the existence of moral facts at this world, if sound, also show that moral facts are impossible, at least at worlds non-morally identical to our own and, on some versions of the error theory, at any world. So error theorists’ (...) arguments warrant a stronger conclusion than has previously been noticed. This may appear to make them vulnerable to counterarguments that take the possibility of moral facts as a premise. However, I show that any such arguments would be question-begging. (shrink)

In view of the critique of the methodology of the dominant interdisciplinary re-search involving language studies as the main component, in particular clinical linguistics, Cummings (2014) proposes that “It is perhaps appropriate at this point to move the debate onto non-empirical grounds.” In Cummings (2014: 113) she starts such a debate on the grounds of the philosophy of language and pragmatics. In this article, I propose to expand that debate by including the input of the philosophy of science. I start (...) the discussion by presenting the way one may carry out language research in the paradigm of empirical sciences from the perspective outlined in Bunge (1967, 1973, 2003) and constrained by Altmann’s (1978) assumption about self-originating and self-regulatory nature of language.

The relation of ontological dependence or grounding, expressed by the terminology of separation and priority in substance, plays a central role in Aristotle’s Categories, Metaphysics, De Anima and elsewhere. The article discusses three current interpretations of this terminology. These are drawn along the lines of, respectively, modal-existential ontological dependence, essential ontological dependence, and grounding or metaphysical explanation. I provide an opinionated introduction to the topic, raising the main interpretative questions, laying out a few of the exegetical and philosophical options that (...) influence one’s reading, and locating questions of Aristotle scholarship within the discussion of ontological dependence and grounding in contemporary metaphysics.

Both literalism, the view that mathematical objects simply exist in the empirical world, and fictionalism, the view that mathematical objects do not exist but are rather harmless fictions, have been both ascribed to Aristotle. The ascription of literalism to Aristotle, however, commits Aristotle to the unattractive view that mathematics studies but a small fragment of the physical world; and there is evidence that Aristotle would deny the literalist position that mathematical objects are perceivable. The ascription of fictionalism also faces a (...) difficult challenge: there is evidence that Aristotle would deny the fictionalist position that mathematics is false. I argue that, in Aristotle's view, the fiction of mathematics is not to treat what does not exist as if existing but to treat mathematical objects with an ontological status they lack. This form of fictionalism is consistent with holding that mathematics is true. (shrink)

Compte tenu de la critique de la méthodologie de la recherche interdisciplinaire dominante impliquant des études linguistiques comme élément principal, en particulier la linguistique clinique, Cummings (2014) propose qu’« il est peut-être approprié à ce stade de déplacer le débat sur des bases non empiriques ». Dans Cummings (2014), elle entame un tel débat sur la base de la philosophie de la langue et de la pragmatique. Dans cet article, je propose d’élargir ce débat en incluant l’apport de la philosophie (...) de la science. Je présente la façon dont on peut mener des recherches linguistiques dans le paradigme des sciences empiriques tel qu’exposé dans Bunge (1967, 1973, 2003) et limité par l’hypothèse d’Altmann (1978) sur la nature autocréée et autorégulatrice du langage.

A predicate logic typically has a heterogeneous semantic theory. Subjects and predicates have distinct semantic roles: subjects refer; predicates characterize. A sentence expresses a truth if the object to which the subject refers is correctly characterized by the predicate. Traditional term logic, by contrast, has a homogeneous theory: both subjects and predicates refer; and a sentence is true if the subject and predicate name one and the same thing. In this paper, I will examine evidence for ascribing to Aristotle the (...) view that subjects and predicates refer. If this is correct, then it seems that Aristotle, like the traditional term logician, problematically conflates predication and identity claims. I will argue that we can ascribe to Aristotle the view that both subjects and predicates refer, while holding that he would deny that a sentence is true just in case the subject and predicate name one and the same thing. In particular, I will argue that Aristotle's core semantic notion is not identity but the weaker relation of constitution. For example, the predication ‘All men are mortal’ expresses a true thought, in Aristotle's view, just in case the mereological sum of humans is a part of the mereological sum of mortals. (shrink)

Is there grounding in ancient philosophy? To ask a related but different question: is grounding a useful tool for the scholar of ancient philosophy? These questions are difficult, and my goal in this paper is not so much to give definitive answers as to clarify the questions. I hope to direct the student of contemporary metaphysics towards passages where it may be fruitful to look for historical precedent. But I also hope to offer the student of ancient philosophy some guidance (...) on when drawing on the contemporary discussion of grounding may be beneficial. (shrink)

Politics, and in particular the question of the Palestinian-Israeli conflict, is currently dealt with rather through fiction and art, and much less through genuine political actions, is a strong sign of the failure of politics as a positive, voluntaristic political project. Rap /hip hop music, the most naturally political art, does not have the political agenda anymore. The particular history or Israeli rap illustrates this process in a striking way, embodying the recent evolution of the Israeli society. The country was (...) established on a political project and previously unknown social generosity. Yet, the economical and geopolitical context of Israel, as well as increasingly difficult relationship with Palestinians, made its citizens surprisingly uninterested in rethinking the political project of the country. Individual preoccupations, also economical, family and friends’ problems, started to occupy the central place in art and in daily life in Israel, and politics has been definitively associated to corruption and self-interest of an elite. Rap reflects this evolution, is its condensed version. (shrink)

Discussion of the Aristotelian syllogistic over the last sixty years has arguably centered on the question whether syllogisms are inferences or implications. But the significance of this debate at times has been taken to concern whether the syllogistic is a logic or a theory, and how it ought to be represented by modern systems. Largely missing from this discussion has been a study of the few passages in the Prior Analytics where Aristotle provides explicit guidance on how to individuate syllogisms. (...) I argue that syllogisms are individuated by unordered premise pairs and so may be fruitfully thought of as multi-succedent sequents. I conclude by drawing a few consequences for the representation of the syllogistic. (shrink)

Causal pluralists hold that that there is not just one determinate kind of causation. Some causal pluralists hold that ‘cause’ is ambiguous among these different kinds. For example, Hall (2004) argues that ‘cause’ is ambiguous between two causal relations, which he labels dependence and production. The view that ‘cause’ is ambiguous, however, wrongly predicts zeugmatic conjunction reduction, and wrongly predicts the behaviour of ellipsis in causal discourse. So ‘cause’ is not ambiguous. If we are to disentangle causal pluralism from the (...) ambiguity claim, we need to consider what other linguistic approaches are available to the causal pluralist. I consider and reject proposals that ‘cause’ is a general term, that the term is an indexical, and that the term conveys different kinds of causation through implicature or presupposition. Finally, I argue that causal pluralism is better handled by treating ‘cause’ as a univocal term within a dynamic interpretation framework. (shrink)

Although few linguists currently embrace the empirical paradigm, there are increasing calls for the development of tools for studying language that resemble those in exact sciences. This trend can be observed even in top mainstream linguistic journals, such as the Journal of Pragmatics, as exemplified by Xiang (2017). Today, however, linguists who adapt the methodologies from more advanced sciences face isolation from the mainstream linguistic community. This is because the majority of linguists in philological and philosophical departments remain convinced that (...) the object of their studies is fundamentally different from those studied by physicists. Therefore, they argue that linguistic methodology cannot resemble that used in empirical sciences. As a result, linguistics is often seen as requiring interpretation rather than an explanation, and evaluation of linguistic research is based on acceptance within the scholarly community rather than empirical testing.

When Aristotle introduces the perfect moods, he refers back to the dictum de omni et nullo, a semantic condition for universal affirmations and negations. There recently has been renewed interest in the question whether the dictum validates the assertoric syllogistic. I rehearse evidence that Aristotle provides a mereological semantics for universal affirmations and negations, and note that this semantics entails a nonstandard reading of the dictum, under which the dictum, in the presence of a minimal logical apparatus, indeed validates the (...) assertoric syllogistic. I argue that this mereological validation offers advantages over recent discussions in Morison, Malink, Ebert and Vlasits. (shrink)

Plotinus holds an important position in the history of late ancient philosophy on the concept of human agency. On the one hand, he follows Plato in regarding a human agent as one who self-identifies with the rational soul, becomes one from many, and acts from reason (Republic, 443de). On the other hand, due to the view characteristic of the second century CE that destiny causally determines the sensible world and sophisticated debates concerning freedom and determinism up to, and during, the (...) second century CE, Plotinus develops Plato’s view further in an effort to meet the challenges posed by earlier determinists. The position he develops in the Enneads is a dynamic synthesis of Platonic, Peripatetic, Stoic, and Middle-Platonic theorizing on human causation that shows how one can be a self-determining agent even while living in a world governed by destiny. I argue that the key to understanding Plotinus’ theory of human agency is to understand the role that consciousness plays since he holds that in order to be the sole causal source of our actions, and therefore truly self-determining, we must derive our premises for action from Intellect. Important for my purposes is his peculiar view that Intellect is also “in ourselves” (V.1.10.5-8) and can be reached by turning inwards and ascending upwards which is possible through possessing a unique mode of consciousness, namely awareness (sunaisthēsis).

Aristotle draws what are, by our lights, two unusual relationships between predication and existence. First, true universal affirmations carry existential import. If ‘All humans are mortal’ is true, for example, then at least one human exists. And secondly, although affirmations with empty terms in subject position are all false, empty negations are all true: if ‘Socrates’ lacks a referent, then both ‘Socrates is well’ and ‘Socrates is ill’ are false but both ‘Socrates is not well’ and ‘Socrates is not ill’ (...) are true. In this paper, I conjecture that for Aristotle predications have mereological truth conditions: for example, ‘Socrates is pale’ is true just in case Socrates is a part of the mereological sum of pale things. The existential import of universal affirmations and the semantic profile of empty negations follow from this mereological semantics. (shrink)
