This paper discusses Marx’s critique of the market in the light of Allan Megill’s recent book, Karl Marx: the Burden of Reason. Megill offers two main arguments concerning Marx’s critique. Firstly, Megill claims that, contrary to Marxian orthodoxy, Marx’s well-known theory of alienation does not in fact amount to an unambiguous critique of market society – in particular, Megill maintains that Marx lacks a clear argument demonstrating that worker alienation is an inevitable effect of the system of private property. Secondly, (...) Megill claims that the real reason why Marx rejected the market was because Marx could not account for the market’s arbitrary behaviour in terms of his rationalist conception of science (which Megill characterises, roughly speaking, as a synthesis of Hegel’s rationalism and Newtonianism). I take issue with Megill’s reading of Marx on three counts. Firstly, I claim, in opposition to Megill, that Marx does indeed have a coherent theory of alienation and one that undoubtedly implies that worker freedom and private property are incompatible. Secondly, I contend that Marx was not actually committed to scientific rationalism and hence could not have been opposed to the market on such grounds. Thirdly, I submit that Marx’s deep misgivings about market anarchy were based instead on his belief that the arbitrary nature of the market was a major barrier to individual freedom (and moreover formed an integral part of the whole system of private property). Finally, I discuss Marx’s claim that a fully planned economy is an essential prerequisite for the full and proper realisation of individual freedom, and consider, briefly, in this light, whether market socialism might in fact be a superior instrument for the fulfilment of Marx’s emancipatory aims.

In this paper, we introduce and defend the recurrent model for understanding bodily spatial phenomenology. While Longo, Azañón and Haggard (2010) propose a bottom-up model, Bermúdez (2017) emphasizes the top-down aspect of the information processing loop. We argue that both are only half of the story. Section 1 intro- duces what the issues are. Section 2 starts by explaining why the top- down, descending direction is necessary with the illustration from the ‘body-based tactile rescaling’ paradigm (de Vignemont, Ehrsson and Haggard, (...) 2005). It then argues that the bottom-up, ascending direction is also necessary, and substantiates this view with recent research on skin space and tactile field (Haggard et al., 2017). Section 3 discusses the model’s application to body ownership and bodily self-representation. Implications also extend to topics such as sense modality individuation (Macpherson, 2011), the constancy- based view of perception (Burge, 2010), and the perception/cognition divide (Firestone and Scholl, 2016).

The notion that human activity can be characterised in terms of dynamic systems is a well-established alternative to motor schema approaches. Key to a dynamic systems approach is the idea that a system seeks to achieve stable states in the face of perturbation. While such an approach can apply to physical activity, it can be challenging to accept that dynamic systems also describe cognitive activity. In this paper, we argue that creativity, which could be construed as a ‘cognitive’ activity par (...) excellence, arises from the dynamic systems involved in jewellery making. Knowing whether an action has been completed to a ‘good’ standard is a significant issue in considering acts in creative disciplines. When making a piece of jewellery, there a several criteria which can define ‘good’. These are not only the aesthetics of the finished piece but also the impact of earlier actions on subsequent ones. This suggests that the manner in which an action is coordinated is influenced by the criteria by which the product is judged. We see these criteria as indicating states for the system, e.g. in terms of a space of ‘good’ outcomes and a complementary space of ‘bad’ outcomes. The skill of the craftworker is to navigate this space of available states in such a way as to minimise risk, effort and other costs and maximise benefit and quality of the outcome. In terms of postphenomonology, this paper explores Ihde’s human-technology relations and relates these to the concepts developed here. (shrink)

Substantial research examines the follower consequences of leader alignment of words and deeds, but no research has quantitatively reviewed these effects. This study examines extant research on behavioral integrity and contrasts it with two other constructs that focus on alignment: moral integrity and psychological contract breaches. We compare effect sizes between the three constructs, and find that BI has stronger effects on trust, in-role task performance and citizenship behavior than moral integrity and stronger effects on commitment and OCB than psychological (...) contract breach. These stronger attitudinal consequences run counter to our initial expectations, but they provide evidence of important conceptual distinctions and mechanisms that we articulate. BI theory suggests that BI’s greater performance impact is due to the notion that BI affects communication clarity in addition to attitudes. Results of meta-analytic structural equation modeling are consistent with this proposed dual path of BI’s impact. We highlight avenues for future research on BI and discuss how our findings inform the broader research on leader alignment. (shrink)

There have recently been various empirical attempts to answer Molyneux’s question, for example, the experiments undertaken by the Held group. These studies, though intricate, have encountered some objections, for instance, from Schwenkler, who proposes two ways of improving the experiments. One is “to re-run [the] experiment with the stimulus objects made to move, and/or the subjects moved or permitted to move with respect to them” (p. 94), which would promote three dimensional or otherwise viewpoint-invariant representations. The other is “to use (...) geometrically simpler shapes, such as the cube and sphere in Molyneux’s original proposal, or planar figures instead of three-dimensional solids” (p. 188). Connolly argues against the first modification but agrees with the second. In this article, I argue that the second modification is also problematic (though still surmountable), and that both Schwenkler and Connolly are too optimistic about the prospect of addressing Molyneux’s question empirically.

Aristotle and Natural Law lays out a new theoretical approach which distinguishes between the notions of 'interpretation,' 'appropriation,' 'negotiation' and 'reconstruction' of the meaning of texts and their component concepts. These categories are then deployed in an examination of the role which the concept of natural law is used by Aristotle in a number of key texts. The book argues that Aristotle appropriated the concept of natural law, first formulated by the defenders of naturalism in the 'nature versus convention debate' (...) in classical Athens. Thereby he contributed to the emergence and historical evolution of the meaning of one of the most important concept in the lexicon of Western political thought. Aristotle and Natural Law argues that Aristotle's ethics is best seen as a certain type of natural law theory which does not allow for the possibility that individuals might appeal to natural law in order to criticize existing laws and institutions. Rather its function is to provide them with a philosophical justification from the standpoint of Aristotle's metaphysics. (shrink)

This paper is about the contemporary debate concerning folk psychology – the debate between the proponents of the theory theory of folk psychology and the friends of the simulation alternative.¹ At the outset, we need to ask: What should we mean by this term ‘folk psychology’?

In this letter we focus on the cognitive science of consciousness. The general message is that, while this interdisciplinary area has made much progress in recent years, there is a tendency of downplaying conceptual issues, and therefore underestimating the difficulties of various problems. We briefly focus on a few prominent examples only, due to the space limit, but the general message should be clear: this recent tendency can be problematic for the progress of the consciousness branch of cognitive sciences.

The obesity epidemic is not only impairing the health of millions of Americans but also giving rise to billions of added dollars in health care spending. Climbing rates of obesity over the past decades are one of the predominant determinants behind the surging progression of health care expenses in the United States. Moreover, the less fit and less productive U.S. workforce has gradually eroded the nation’s industrial competitiveness. Since the early 1970s, adult obesity rates have doubled and childhood obesity rates (...) have more than tripled, while health expenditures have risen two percentage points faster than the Gross Domestic Product, burgeoning from 8.8 percent in 1980 to a projected 17.9 percent in 2011. Studies analyze that greater than a quarter of America’s health care expenses are attributed to obesity. The stunning growth in obesity has been imputed for 20 to 30 percent of the increase in health care costs since the late 1970s. If the proportion of obese population had stayed unchanged, then health care expenditures in America would be approximately 10 percent less on a per capita average than they are today. (shrink)

The call for family and medical leave reform in the United States was largely the result of sweeping demographic shifts that occurred in the workforce after the 1950s, coupled with an ever-increasing life expectancy and changing social norms concerning the role of women as caretakers. By the early 1990s, the number of women in the workforce had nearly tripled from 1950. During that same period, life expectancy increased by six years for males and seven for females. Meanwhile, the first wave (...) of the Depression-era generation began to reach the age of retirement. In short, the parents of American workers were living longer and retiring in greater numbers while more women, who were more likely to be informal caregivers, decided to join the workforce. As a result, many families with ill or elder parents began to turn to institutional long-term care. (shrink)

Avicenna refers on a number of occasions in his Book of the Syllogism to “the eminent later scholar” . At least three recent studies have argued or assumed that this eminent later scholar is Alexander of Aphrodisias. It is argued in this article that Avicenna is in fact referring to Alfarabi. This has consequences for reconstructing the lost first part of Alfarabi's Great Commentary on the Prior Analytics , for highlighting certain aspects of Alfarabi's logical doctrines, and for understanding more (...) about the relation between Avicenna and Alfarabi in matters logical.

A major and timely re-examination of key areas in the social and political thought of Hegel and Marx. The editors' extensive introduction surveys the development of the connection from the Young Hegelians through the main Marxist thinkers to contemporary debates. Leading scholars including Terrell Carver, Chris Arthur, and Gary Browning debate themes such as: the nature of the connection itself scientific method political economy the Hegelian basis to Marxs' "Doctoral Dissertation" human needs history and international relations.

BackgroundThe Health Research Council of New Zealand is the first major government funding agency to use a lottery to allocate research funding for their Explorer Grant scheme. This is a somewhat controversial approach because, despite the documented problems of peer review, many researchers believe that funding should be allocated solely using peer review, and peer review is used almost ubiquitously by funding agencies around the world. Given the rarity of alternative funding schemes, there is interest in hearing from the first (...) cohort of researchers to ever experience a lottery. Additionally, the Health Research Council of New Zealand wanted to hear from applicants about the acceptability of the randomisation process and anonymity of applicants.MethodsThis paper presents the results of a survey of Health Research Council applicants from 2013 to 2019. The survey asked about the acceptability of using a lottery and if the lottery meant researchers took a different approach to their application.ResultsThe overall response rate was 39%, with 30% from applicants in the years 2013 to 2018, and 68% for those in the year 2019 who were not aware of the funding result. There was agreement that randomisation is an acceptable method for allocating Explorer Grant funds with 63% in favour and 25% against. There was less support for allocating funds randomly for other grant types with only 40% in favour and 37% against. Support for a lottery was higher amongst those that had won funding. Multiple respondents stated that they supported a lottery when ineligible applications had been excluded and outstanding applications funded, so that the remaining applications were truly equal. Most applicants reported that the lottery did not change the time they spent preparing their application.ConclusionsThe Health Research Council’s experience through the Explorer Grant scheme supports further uptake of a modified lottery.

Given the nature of the discipline, it might be assumed that clinical psychology is an ethical profession, within which effective ethical decision-making is integral. How then, does this ethical decision-making occur? This paper describes a systematic review of empirical research addressing this question. The paucity of evidence related to this question meant that the scope was broadened to include other professions who deliver talking therapies. This review could support reflective practice about what may be taken into account when making ethical (...) decisions and highlight areas for future research. Using academic search databases, original research articles were identified from peer-reviewed journals. Articles using qualitative, quantitative and mixed methods were included. Two theoretical models of aspects of ethical decision-making were identified. Areas of agreement and debate are described in relation to factors linked to the professional, which impacted ethical decision-making. Factors relating to ethical dilemmas, which impacted ethical decision-making, are discussed. Articles were appraised by two independent raters, using quality assessment criteria, which suggested areas of methodological strengths and weaknesses. Comparison and synthesis of results revealed that the research did not generally pertain to current clinical practice of talking therapies or the particular socio-political context of the UK healthcare system. There was limited research into ethical decision-making amongst specific professions, including clinical psychology. Generalisability was limited due to methodological issues, indicating avenues for future research. (shrink)

To reduce the spread of the human immunodeficiency virus (HIV), Granich et al. 1 ( 2009 ) have proposed a new strategy for universal voluntary HIV testing immediately followed by antiretroviral therapy. Although this proposal is likely to benefit the partners of those affected and thus promote public health, it is by no means clear that it benefits the infected people themselves and indeed it may be harmful. Since the proposal involves an intervention that is not clinically indicated, it falls (...) foul of the normal ethical standards of clinical medicine, which is to act in the best interests of patients. Neither is it a measure that would be imposed under the protection of public health law on people who are seen as representing such danger to others that significant restrictions in liberty are appropriate. Thus, the proposal represents a third category of public health measure. We argue that a coherent ethical framework including a robust process is appropriate to proposals of this kind and that medical research offers a useful model since some research, like this proposal, is motivated not by the interests of the individual participants but by the common good. We outline some possible elements of such an ethical framework. (shrink)

This paper investigates the complicated relations between various versions of naturalism, behaviorism, and mentalism within the framework of W. V. O. Quine's thinking. It begins with Roger Gibson's reconstruction of Quine's behaviorisms and argues that it lacks a crucial ontological element and misconstrues the relation between philosophy and science. After getting clear of Quine's naturalism, the paper distinguishes between evidential, methodological, and ontological behaviorisms. The evidential and methodological versions are often conflated, but they need to be clearly distinguished in order (...) to see whether Quine's argument against mentalism is cogent. The paper argues that Quine's naturalism supports only the weakest version of behaviorism, that is, the evidential one, but this version is compatible with mentalistic semantics. Quine's opposition to mentalism is an overreaction from the behaviorist camp. By contrast, Jerry Fodor's objection to Jose Luis Bermudez is an overreaction from the opposite direction. (shrink)

This paper examines the resonances between Deleuze's theory of subjectivity and the Buddhist view of subjectivity. Although much scholarship has been focused on Deleuze's theory of subjectivity, relatively little has been directed at a comparative study of how his theory of subjectivity resonates with the idea of de-centred subjectivity in Buddhist philosophy. In addition to this, the paper explores the ethical and political implications of such a notion of subjectivity. In the first part, it examines Deleuze's theory of subjectivity and (...) in the second part, it examines the theory of subjectivity in Buddhist philosophy. In the third part, it considers the ethical implications of the Deleuzian and Buddhist theory of subjectivity. (shrink)

In the present article, I attempt to relate Saul Kripke's “sceptical paradox” to some issues about the self; specifically, the relation between the self and its mental states and episodes. I start with a brief reconstruction of the paradox, and venture to argue that it relies crucially on a Cartesian model of the self: the sceptic regards the Wittgensteinian “infinite regress of interpretation” as the foundation of his challenge, and this is where he commits the crucial mistake. After the diagnosis, (...) I attempt to sketch my own model of the self and its mental states and episodes. This tentative picture binds meaning and the self together, stressing the subjective aspect of meaning without committing the same fallacy. The solution ventured here is relatively independent of the secondary literatures on the sceptical paradox of following rules, for it aims to provide a new angle to understand and meet the challenge presented by the sceptic.

This book brings together perspectives on predictive processing and expected experience. It features contributions from an interdisciplinary group of authors specializing in philosophy, psychology, cognitive science, and neuroscience. Predictive processing, or predictive coding, is the theory that the brain constantly minimizes the error of its predictions based on the sensory input it receives from the world. This process of prediction error minimization has numerous implications for different forms of conscious and perceptual experience. The chapters in this volume explore these implications (...) and various phenomenon related to them. The contributors tackle issues related to precision estimation, sensory prediction, probabilistic perception, and attention, as well as the role predictive processing plays in emotion, action, psychotic experience, anosognosia, and gut complex. Expected Experiences will be of interest to scholars and advanced students in philosophy, psychology, and cognitive science working on issues related to predictive processing and coding. (shrink)

This paper develops the situational model of primate beliefs from the Prior-Lurz line of thought. There is a strong skepticism concerning primate beliefs in the analytic tradition which holds that beliefs have to be propositional and non-human animals do not have them. The response offered in this paper is twofold. First, two arguments against the propositional model as applied to other animals are put forward: an a priori argument from referential opacity and an empirical argument from varieties of working memory. (...) Second, the Prior-Lurz situational model based on state of affairs as opposed to propositions is introduced and defended with two significant modifications. With this model of primate beliefs we can make progress in understanding how other primates can have certain mindreading capacity. (shrink)

The term “consciousness” is very often, though not always, interchangeable with the term “awareness,” which is more colloquial to many ears. We say things like “are you aware that ...” often. Sometimes we say “have you noticed that ... ?” to express similar thoughts, and this indicates a close connection between consciousness (awareness) and attention (noticing), which we will come back to later in this chapter. Ned Block, one of the key figures in this area, provides a useful characterization of (...) what he calls “phenomenal consciousness.” For him, phenomenal consciousness is experience. Experience covers perceptions, e.g., when we see, hear, touch, smell, and taste, we typically have experiences, such as seeing colors and smelling odors. It also covers bodily awareness, e.g., we typically have experiences of our own bodily temperature and positions of limbs. Consciousness is primarily about this experiential aspect of our mental lives. (shrink)

This article attempts to highlight the importance of including research sustainability as imperative when assessing human medical research in terms of ethical principles. Using a scoping review of recent literature, the complexity of research sustainability is highlighted with key themes and concepts surrounding this important topic being recognized and discussed. An overall paucity of guidance documents was identified and recommendations have been made to practically address this deficiency. An example of a research sustainability evaluation tool which is currently being piloted (...) has been provided for possible adaptation and use by Ethics Committees and Institutional Review Boards to bolster the concept and inclusion of sustainability during the research approval process.

In a world of confrontations between numerous cultures, traditions, languages, and religions, the meaning of “human” and “humanism” reaches a higher level of “humanness.” The pluralism of cultural, political, and religious outlook creates new options and alternative interpretations of what constitutes the “human.” True humanness is always there, open and accessible to all, with nothing being hidden or obscured. At the same time, true humanness is also a matter of doing, not just being. To be “true” is to live the (...) truth, to be with it, and to be part of it. We exist inside this truth as a passion, which informs all the decisions we make in life. So true humanness is not something objective and static, something to be studied from a distance; true humanness is an up-close and personal way of living, a mode of existence, something that is relational. Our way toward a more complex understanding of humanness faces similar obstacles as a yogi encounters on his way to the final way of Yoga. Patañjali in his Yoga Sutras describes these obstacles—kleshas—as the afflictions of the human mind, or destructive and disturbing emotions: ignorance, ego, attachment, aversion, and clinging to life. A higher understanding of “humanness” will not be reached without an ethical engagement of individuals, as well as formal and informal commitment of institutions and nations. Such an endeavor will consequently reveal yet-undiscovered human potential, leading to a renaissance of our acting, thinking, and believing. (shrink)

Rowlands’s case for attributing personhood to lower animals is ultimately convincing, but along the way he fails to highlight several distinctions that are crucial for his argument: Personhood vs. personal identity; the first person vs. its mental episodes; and pre- reflective awareness in general vs. one specific case of it.

Timothy Williamson’s Knowledge and its Limits has been highly influential since the beginning of this century. It can be read as a systematic response to scepticism. One of the most important notions in this response is the notion of «evidence,» which will be the focus of the present paper. I attempt to show primarily two things. First, the notion of evidence invoked by Williamson does not address the sceptical worry: he stipulates an objective notion of evidence, but this begs the (...) question against his opponent. Second, his related thesis «Evidence equals Knowledge» does not sit well with his own content externalism: he promises to relate epistemology to philosophy of mind, but he fails to live up to this commitment in his crucial chapter on scepticism. Other minor problems concerning evidence will also be discussed in due course. (shrink)

In this paper I defend a pluralistic approach in understanding function, both in biological and other contexts. Talks about function are ubiquitous and crucial in biology, and it might be the key to bridge the “manifest image” and the “scientific image” identified by Sellars (1962). However, analysis of function has proven to be extremely difficult. The major puzzle is to make sense of “time-reversed causality”: how can property P be the cause of its realizer R? For example, “pumping blood” is (...) a property of hearts, but a property of hearts cannot be the cause of the presence of hearts, since properties cannot predate their realizers and be causes of them. In section 2 I discuss Wright’s etiological analysis, Cummins’ causal-role analysis, and their critics. In section 3 I defend a version of the “consensus without unity” strategy proposed by Godfrey-Smith from Christopher Boorse’s recent critique (2002). In Section 4 I conclude by reflecting on the relation between functional discourses and physicalism. (shrink)

This paper is about compositionality, belief reports, and related issues. I begin by introducing Putnam’s proposal for understanding compositionality, namely that the sense of a sentence is a function of the sense of its parts and of its logical structure (section 1). Both Church and Sellars think that Putnam’s move is superfluous or unnecessary since there is no relevant puzzle to begin with (section 2). I will urge that Putnam is right in thinking that there is indeed a puzzle with (...) a discussion of translation and belief individuation (section 3). Later Salmon (2001/ 2007) reinforces Church’s position, but I will argue that it is still possible to make my case by clarifying the nature of my proposal, i.e., understanding explanations of action from the third-person point of view (section 4). Now, Fine (2007) agrees with Putnam that there is indeed a puzzle to be solved, but he argues that Putnam’s solution of it is problematic, and that his own semantic relationism is a better view. In response to this, I will recast the notion of compositionality based on a certain conception of belief individuation, namely that the semantic content of a sentence is a function of the semantic contents of its parts and of the structure of intensional discourses (sections 3 and 5). Finally the paper will end with a reconsideration of the recalcitrant Kripke’s puzzle about belief (1979/1988), since it might seem to put some pressure on my account. It turns out that my understanding of this puzzle is again different from Fine’s perspective (section 6). (shrink)

In a series of works Hubert Dreyfus argues that phenomenological considerations can show the falsity of John McDowell’s claim that ours actions are permeated with rationality. Dreyfus changes the details of his objections several times in this debate, but I shall argue that there is an implicit false assumption lurking in his thinking throughout his exchanges with McDowell. Originally Dreyfus proposed a distinction between “detached rule-following” and “situation-specific way of coping,” and later he replaces it with the distinction between “subjectivity” (...) and “absorbed coping.” He then uses this framework to interpret some examples, attempting to show that they cannot be accommodated by McDowell’s position. I shall argue that in doing so Dreyfus presupposes too narrow conceptions of “rationality” and “mindedness,” and if these notions are understood appropriately, we can see that phenomenological considerations can be good supplements, rather than objections, to McDowell’s claim that our mindedness is pervasive in actions.

A computational modeling approach was used to test one possible explanation for the limited capacity of the subitizing phenomenon. Most existing models of this phenomenon associate the subitizing span with an assumed structural limitation of the human information processing system. In contrast, we show how this limit might emerge as the combinatorics of the space of enumeration problems interacts with the human cognitive architecture in the context of an enumeration task. Subitizing‐like behavior was generated in two different models of enumeration, (...) one based on the ACT‐R cognitive architecture and the other based on the principles of parallel distributed processing (PDP). Our results provide good qualitative fits to results obtained in a variety of empirical studies. (shrink)

This paper offers an account of propositional absurdity and investigates its connection to falsity. I propose that instances of absurdity just are cases of what I call maximal abnormality. In light of the works of Smith (2016) and Pietroski and Rey (1995) on normic conditionals which link normality to explanatory demands, I suggest that absurdity also has a close tie with explanations (more precisely, the lacking thereof). Interesting consequences follow under such an account – first, I argue that we should (...) see absurdity as ceteris paribus guide to falsehood – what is absurd is expected to be false, unless further evidence suggests otherwise; second (and relatedly), when further evidence indeed suggests otherwise, absurd propositions would not cease to be absurd.

Visual stimuli as well as transcranial magnetic stimulation can be used: to suppress the visibility of a target and to recover the visibility of a target that has been suppressed by another mask. Both types of stimulation thus provide useful methods for studying the microgenesis of object perception. We first review evidence of similarities between the processes by which a TMS mask and a visual mask can either suppress the visibility of targets or recover such suppressed visibility. However, we then (...) also point out a significant difference that has important implications for the study of the time course of unconscious and conscious visual information processing and for theoretical accounts of the processes involved. We present evidence and arguments showing: that visual masking techniques, by revealing more detailed aspects of target masking and target recovery, support a theoretical approach to visual masking and visual perception that must take into account activities in two separate neural channels or processing streams and, as a corollary, that at the current stage of methodological sophistication visual masks, by acting in more highly specifiable ways on these pathways, provide information about the microgenesis of form perception not available with TMS masks.
