By looking at the politics of classification within machine learning systems, this article demonstrates why the automated interpretation of images is an inherently social and political project. We begin by asking what work images do in computer vision systems, and what is meant by the claim that computers can “recognize” an image? Next, we look at the method for introducing images into computer systems and look at how taxonomies order the foundational concepts that will determine how a system interprets the (...) world. Then we turn to the question of labeling: how humans tell computers which words will relate to a given image. What is at stake in the way AI systems use these labels to classify humans, including by race, gender, emotions, ability, sexuality, and personality? Finally, we turn to the purposes that computer vision is meant to serve in our society—the judgments, choices, and consequences of providing computers with these capacities. Methodologically, we call this an archeology of datasets: studying the material layers of training images and labels, cataloguing the principles and values by which taxonomies are constructed, and analyzing how these taxonomies create the parameters of intelligibility for an AI system. By doing this, we can critically engage with the underlying politics and values of a system, and analyze which normative patterns of life are assumed, supported, and reproduced. (shrink)

There are growing discontinuities between the research practices of data science and established tools of research ethics regulation. Some of the core commitments of existing research ethics regulations, such as the distinction between research and practice, cannot be cleanly exported from biomedical research to data science research. Such discontinuities have led some data science practitioners and researchers to move toward rejecting ethics regulations outright. These shifts occur at the same time as a proposal for major revisions to the Common Rule—the (...) primary regulation governing human-subjects research in the USA—is under consideration for the first time in decades. We contextualize these revisions in long-running complaints about regulation of social science research and argue data science should be understood as continuous with social sciences in this regard. The proposed regulations are more flexible and scalable to the methods of non-biomedical research, yet problematically largely exclude data science methods from human-subjects regulation, particularly uses of public datasets. The ethical frameworks for Big Data research are highly contested and in flux, and the potential harms of data science research are unpredictable. We examine several contentious cases of research harms in data science, including the 2014 Facebook emotional contagion study and the 2016 use of geographical data techniques to identify the pseudonymous artist Banksy. To address disputes about application of human-subjects research ethics in data science, critical data studies should offer a historically nuanced theory of “data subjectivity” responsive to the epistemic methods, harms and benefits of data science and commerce.

Psychologists have demonstrated the value of diversity – particularly diversity of viewpoints – for enhancing creativity, discovery, and problem solving. But one key type of viewpoint diversity is lacking in academic psychology in general and social psychology in particular: political diversity. This article reviews the available evidence and finds support for four claims: (1) Academic psychology once had considerable political diversity, but has lost nearly all of it in the last 50 years. (2) This lack of political diversity can undermine (...) the validity of social psychological science via mechanisms such as the embedding of liberal values into research questions and methods, steering researchers away from important but politically unpalatable research topics, and producing conclusions that mischaracterize liberals and conservatives alike. (3) Increased political diversity would improve social psychological science by reducing the impact of bias mechanisms such as confirmation bias, and by empowering dissenting minorities to improve the quality of the majority's thinking. (4) The underrepresentation of non-liberals in social psychology is most likely due to a combination of self-selection, hostile climate, and discrimination. We close with recommendations for increasing political diversity in social psychology. (shrink)

This paper explores how political theory may help us map algorithmic logics against different visions of the political. Drawing on Chantal Mouffe’s theories of agonistic pluralism, this paper depicts algorithms in public life in ten distinct scenes, in order to ask the question, what kinds of politics do they instantiate? Algorithms are working within highly contested online spaces of public discourse, such as YouTube and Facebook, where incompatible perspectives coexist. Yet algorithms are designed to produce clear “winners” from information contests, (...) often with little visibility or accountability for how those contests are designed. In isolation, many of these algorithms seem the opposite of agonistic: much of the complexity of search, ranking, and recommendation algorithms is nonnegotiable and kept far from view, inside an algorithmic “black box.” But what if we widen our perspective? This paper suggests agonistic pluralism as both a design ideal for engineers and a provocation to understand algorithms in a broader social context: rather than focusing on the calculations in isolation, we need to account for the spaces of contestation where they operate.

Moritz Schlick, Rudolf Carnap and Herbert Feig are the most prominent of the positivists to formulate views on the mind-body problem (aside from Hempel’s one-off treatment in 1935). While their views differed from each other and changed over time they were all committed to some form of scientific physicalism, though a linguistic or conceptual rather than ontological form of it. In focus here are their views during the heyday of logical positivism and its immediate aftermath, though some initial scene-setting of (...) Schlick’s and Carnap’s pre-positivist views will help to understand the final opposing positions of Carnap and Feigl. (shrink)

What is it to suspend judgment about whether p? Much of the recent work on the nature and normative profile of suspending judgment aims to analyze it as a kind of doxastic attitude. On some of these accounts, suspending judgment about whether p partly consists in taking up a certain higher-order belief about one's deficient epistemic position with respect to whether p. On others, suspending judgment about whether p consists in taking up a sui generis attitude, one that takes the (...) question of whether p? as its content. In this paper, I defend an account on which suspending judgment about whether p is not a matter of taking up a doxastic attitude, but rather a way of intentionally omitting to judge whether p. I then close with a discussion of how an account like mine, which sees suspending judgment as fundamentally practical, rather than doxastic, can accommodate what appear to be distinctively epistemic reasons to suspend judgment.

Immanuel Kant was a German philosopher. He is a central figure of modern philosophy, and set the terms by which all subsequent thinkers have had to grapple. He argued that human perception structures natural laws, and that reason is the source of morality. His thought continues to hold a major influence in contemporary thought, especially in fields such as metaphysics, epistemology, ethics, political philosophy, and aesthetics.

Some philosophers argue that friendship can normatively require us to have certain beliefs about our friends that epistemic norms would prohibit. On this view, we ought to exhibit some degree of doxastic partiality toward our friends, by having certain generally favorable beliefs and doxastic dispositions that concern our friends that we would not have concerning relevantly similar non-friends. Can friendship genuinely make these normative demands on our beliefs, in ways that would conflict with what we epistemically ought to believe? On (...) a widely influential evidentialist approach to thinking about epistemic norms, friendship cannot normatively require things of our beliefs, because friendship cannot generate reasons for belief. And this is due, in part, to the alleged fact that we are incapable of forming beliefs directly in response to, or on the basis of, non-epistemic reasons. In this paper, I argue that this evidentialist response to alleged cases of conflict between friendship and epistemic norms fails. Instead, I argue that friendship cannot generate reasons for belief due to an underappreciated feature of friendship: that being a good friend constitutively involves forming attitudes about one’s friends that are appropriately responsive to the features that one’s friends have that appear to warrant those attitudes. I argue that this feature of friendship helps explain why friendship cannot give us reasons to have beliefs that are doxastically partial. (shrink)

A motivational system approach to avoidance behavior is presented. According to this approach, a motivational state increases the probability of relevant response patterns and establishes the appropriate or “ideal” consummatory stimuli as positive reinforcers. In the case of feeding motivation, for example, hungry rats are likely to explore and gnaw, and to learn to persist in activities correlated with the reception of consummatory stimuli produced by ingestion of palatable substances. In the case of defense motivation, fearful rats are likely to (...) flee or freeze, and to learn to persist in activities correlated with consummatory stimuli produced by flight from a dangerous place. Defense system activation is distinct from alarm reactions. The latter prepare the animal for probable noxious events, involve relatively intense negative affect and extinguish rapidly in situations where the noxious event no longer occurs. In contrast, defense system activation potentiates innate and modified defense reactions, thus preparing the animal for possible, but not necessarily probable, noxious events; it involves little or no negative affect and extinguishes very slowly when the noxious event no longer occurs. With these assumptions and the resulting model we attempt to resolve several long-standing problems in avoidance learning, including the low correlation between negative affect and avoidance performance, differential rates of extinction for avoidance performance and conditioned emotional responses, and evidence that some avoidance responses are much more easily learned than others. In addition, the model has implications for the study of parallels between appetitive and aversive motivation, sign tracking in aversive conditioning, and orientation of flight responses. Historical antecedents and alternative approaches are discussed. (shrink)

Health Humanities draws upon the multiple and expanding fields of enquiry that link health and social care disciplines with the arts and humanities. It aims to encourage innovation and novel cross-disciplinary explorations of how the arts and humanities can inform and transform healthcare, health and wellbeing among researchers, practitioners and the public. It foregrounds a range of scholarship and innovative practice in this field. Through the development of critique and critical theory, it enables readers to question not only current practice (...) in medical and health humanities but also foundational assumptions of healthcare, health and wellbeing. Suitable for students and scholars working in this exciting interdisciplinary field, this book sets out the context for an emergent and innovative field. (shrink)

According to Russellianism (or Millianism), the two sentences ‘Ralph believes George Eliot is a novelist’ and ‘Ralph believes Mary Ann Evans is a novelist’ cannot diverge in truth-value, since they express the same proposition. The problem for the Russellian (or Millian) is that a puzzle of Kaplan’s seems to show that they can diverge in truth-value and that therefore, since the Russellian holds that they express the same proposition, the Russellian view is contradictory. I argue that the standard Russellian appeal (...) to “ways of thinking” or “propositional guises” is not necessary to solve the puzzle. Rather than this retrograde concession to Fregeanism, appeal should be made to second-order belief. The puzzle is solved, and the contradiction avoided, by maintaining that both sentences are indeed true in addition to the sentence ‘Ralph (mistakenly) believes that he does not believe Mary Ann Evans/George Eliot is a novelist’.

The identity theory’s rise to prominence in analytic philosophy of mind during the late 1950s and early 1960s is widely seen as a watershed in the development of physicalism, in the sense that whereas logical behaviourism proposed analytic and a priori ascertainable identities between the meanings of mental and physical-behavioural concepts, the identity theory proposed synthetic and a posteriori knowable identities between mental and physical properties. While this watershed does exist, the standard account of it is misleading, as it is (...) founded in erroneous intensional misreadings of the logical positivists’—especially Carnap’s—extensional notions of translation and meaning, as well as misinterpretations of the positivists’ shift from the strong thesis of translation-physicalism to the weaker and more liberal notion of reduction-physicalism that occurred in the Unity of Science programme. After setting the historical record straight, the essay traces the first truly modern identity theory to Schlick’s pre-positivist views circa 1920 and goes on to explore its further development in Feigl, arguing that the fundamental difference between the Schlick-Feigl identity theory and the more familiar and influential Place-Smart-Armstrong identity theory has resurfaced in the deep and seemingly unbridgeable gulf in contemporary philosophy of consciousness between inflationary mentalism and deflationary physicalism.

One of the most compelling questions still unanswered in neuroscience is how consciousness arises. In this article, we examine visual processing, the parietal lobe, and contralateral neglect syndrome as a window into consciousness and how the brain functions as the mind and we introduce a mechanism for the processing of visual information and its role in consciousness. We propose that consciousness arises from integration of information from throughout the body and brain by the thalamus and that the thalamus reimages visual (...) and other sensory information from throughout the cortex in a default three-dimensional space in the mind. We further suggest that the thalamus generates a dynamic default three-dimensional space by integrating processed information from corticothalamic feedback loops, creating an infrastructure that may form the basis of our consciousness. Further experimental evidence is needed to examine and support this hypothesis, the role of the thalamus, and to further elucidate the mechanism of consciousness. (shrink)

Integrating large language models (LLMs) like GPT-4 into medical ethics is a novel concept, and understanding the effectiveness of these models in aiding ethicists with decision-making can have significant implications for the healthcare sector. Thus, the objective of this study was to evaluate the performance of GPT-4 in responding to complex medical ethical vignettes and to gauge its utility and limitations for aiding medical ethicists. Using a mixed-methods, cross-sectional survey approach, a panel of six ethicists assessed LLM-generated responses to eight (...) ethical vignettes.The main outcomes measured were relevance, reasoning, depth, technical and non-technical clarity, as well as acceptability of GPT-4’s responses. The readability of the responses was also assessed. Of the six metrics evaluating the effectiveness of GPT-4’s responses, the overall mean score was 4.1/5. GPT-4 was rated highest in providing technical (4.7/5) and non-technical clarity (4.4/5), whereas the lowest rated metrics were depth (3.8/5) and acceptability (3.8/5). There was poor-to-moderate inter-rater reliability characterised by an intraclass coefficient of 0.54 (95% CI: 0.30 to 0.71). Based on panellist feedback, GPT-4 was able to identify and articulate key ethical issues but struggled to appreciate the nuanced aspects of ethical dilemmas and misapplied certain moral principles.This study reveals limitations in the ability of GPT-4 to appreciate the depth and nuanced acceptability of real-world ethical dilemmas, particularly those that require a thorough understanding of relational complexities and context-specific values. Ongoing evaluation of LLM capabilities within medical ethics remains paramount, and further refinement is needed before it can be used effectively in clinical settings. (shrink)

Multilevel research strategies characterize contemporary molecular inquiry into biological systems. We outline conceptual, methodological, and explanatory dimensions of these multilevel strategies in microbial ecology, systems biology, protein research, and developmental biology. This review of emerging lines of inquiry in these fields suggests that multilevel research in molecular life sciences has significant implications for philosophical understandings of explanation, modeling, and representation.

Propositionalism is the view that intentional attitudes, such as belief, are relations to propositions. Propositionalists argue that propositionalism follows from the intuitive validity of certain kinds of inferences involving attitude reports. Jubien (2001) argues powerfully against propositions and sketches some interesting positive proposals, based on Russell’s multiple relation theory of judgment, about how to accommodate “propositional phenomena” without appeal to propositions. This paper argues that none of Jubien’s proposals succeeds in accommodating an important range of propositional phenomena, such as the (...) aforementioned validity of attitude-report inferences. It then shows that the notion of a predication act-type, which remains importantly Russellian in spirit, is sufficient to explain the range of propositional phenomena in question, in particular the validity of attitude-report inferences. The paper concludes with a discussion of whether predication act-types are really just propositions by another name. (shrink)

Quine introduced a famous distinction between the ‘notional’ sense and the ‘relational’ sense of certain attitude verbs. The distinction is both intuitive and sound but is often conflated with another distinction Quine draws between ‘dyadic’ and ‘triadic’ (or higher degree) attitudes. I argue that this conflation is largely responsible for the mistaken view that Quine’s account of attitudes is undermined by the problem of the ‘exportation’ of singular terms within attitude contexts. Quine’s system is also supposed to suffer from the (...) problem of ‘suspended judgement with continued belief’. I argue that this criticism fails to take account of a crucial presupposition of Quine’s about the connection between thought and language. The aim of the paper is to defend the spirit of Quine’s account of attitudes by offering solutions to these two problems. (shrink)

Emotional experiences are often described in metaphoric language. A major question in linguistics and cognitive science is whether such metaphoric linguistic expressions reflect a deeper principle of cognition. Are abstract concepts structured by the embodied, sensorimotor domains that we use to describe them? This review presents the argument for conceptual metaphors of affect and summarizes recent findings from empirical studies. These findings show that, consistent with the conceptual metaphor account, the associations between affect and physical domains such as spatial position, (...) musical pitch, brightness, and size which are captured in linguistic metaphors also influence performance on attention, memory and judgment tasks. Despite this evidence, a number of concerns with metaphor as an account of affect representation are considered. (shrink)

The Global Workspace Theory and Information Integration Theory are two of the most currently accepted consciousness models; however, these models do not address many aspects of conscious experience. We compare these models to our previously proposed consciousness model in which the thalamus fills-in processed sensory information from corticothalamic feedback loops within a proposed 3D default space, resulting in the recreation of the internal and external worlds within the mind. This 3D default space is composed of all cells of the body, (...) which communicate via gap junctions and electrical potentials to create this unified space. We use 3D llustrations to explain how both visual and non-visual sensory information may be filled-in within this dynamic space, creating a unified seamless conscious experience. This neural sensory memory space is likely generated by baseline neural oscillatory activity from the default mode network, other salient networks, brainstem, and reticular activating system.

The Beginnings of Nietzsche's Theory of Language is concerned with the years 1865 through Winter/Spring 1870-71. Four texts of Nietzsche's, "Vom Ursprung der Sprache", "Zur Teleologie", "Zu Schopenhauer", and "Anschauung Notes", are translated into English and interpreted from the perspective of Nietzsche's developing theory of language. An examination of the major influences of Schopenhauer, Kant, Eduard von Hartmann, and Frederick A. Lange are pursued. ;Theory, in this work, does not assume that it is possible to take a position of authority (...) or truth in the interpretation of texts, rather that interpretation of texts constitutes an attempt to uncover a discursive practice, to describe a discourse-object. The method used is Nietzsche's method of genealogy, which follows the formation of discourse, at once scattered, discontinuous, and regular and analyzes the process of rarefaction, consolidation and unification in that discourse. Genealogy is exegesis in Nietzsche's sense of it as rumination, as the slow, repetitive, gray activity of deciphering what is documented. Major genealogical nodes or elements of Nietzsche's beginning theory of language are used and reused in different contexts throughout the work, resulting in a cumulative effect which explores specific elements in Nietzsche's thinking about language. ;This work offers five major contributions to Nietzsche studies: a detailed introduction of the significant influence of Eduard von Hartmann upon Nietzsche's thinking; a comprehensive look at the influence of Lange's History of Materialism upon Nietzsche's beginning theory of language; a thorough analysis of "Zur Teleologie" and "Zu Schopenhauer" in the overall contexts of Nietzsche's thinking with regard to metaphysics and teleology; the gathering together and interpretation into a world view of the "Anschauung Notes"; and a close examination of Nietzsche's breaking away from Schopenhauer as it takes place before the publication of The Birth of Tragedy. ;Nietzsche's primary contributions to a theory of language in these beginning years are three: the adoption of the role of the unconscious instincts in the origins and ongoing production of language; the assertion that unconscious thought processes are a precondition for conscious thought; an examination of the relationships of language to epistemology, which results in the recognition of the limits of language as an instrument of truth, but a realization of the inestimable value and force of its symbolic and figurative aspects, aspects necessitated by the very nature of language itself.

The central dispute between evidentialists and pragmatists about reasons for belief concerns whether or not non-evidential considerations can be reasons for belief. In recent work, some pragmatists about reasons for belief have made their case for pragmatism by appealing, in part, to a broad range of cases in which facts about one’s relationships with significant others (friends, romantic partners, and the like) appear to give one non-evidential reasons to have beliefs skewed in their favor. This chapter explores whether and how (...) such relationships might provide non-evidential reasons for belief. After first making the case against the evidentialist’s claim that there cannot be non-evidential reasons for belief, this chapter turns to examine different accounts of how our personal relationships might ground reasons for doxastic partiality. These are accounts on which reasons for doxastic partiality are grounded in facts about what attitudes are partly constitutive of being a good significant other to someone, and accounts on which reasons for doxastic partiality are grounded in reasons, more broadly, to benefit one’s significant others. This chapter argues that our personal relationships do not provide non-evidential reasons for belief, even if the pragmatist is right that there can be non-evidential reasons for belief. (shrink)

The complex activity of the human brain makes it difficult to get a big picture of how the brain works and functions as the mind. We examine pertinent studies, as well as evolutionary and embryologic evidence to support our theoretical model consisting of separate but interactive layers of human neural activity. The most basic layer involves default mode network (DMN)activity and cardiorespiratory oscillations. We propose that these oscillations support other neural activity and cognitive processes. The second layer involves limbic system (...) activity accompanied by corresponding changes in cardiorespiratory oscillations. The third layer consists of corticothalamic processing and involves higher cortical functions including awareness, cognition,and consciousness. These layers interact to form the complex neural activity of the human brain. Examining the origins and relationships of various neural and physiologic oscillations may provide better understanding of human neurophysiology and consciousness. (shrink)

Recent research suggests that people's understanding of the abstract domain of time is dependent on the more concrete domain of space. Boroditsky and Ramscar (2002) found that spatial context influences whether people see themselves as moving through time (ego-moving perspective) or as time moving towards them (time-moving perspective). Based on studies of the embodiment of affective experience, we examined whether affect might also influence which spatial metaphor of time people adopt. The results of Experiments 1 and 2 showed that participants (...) who imagined a negative event were more likely to report that the event was approaching them, whereas those who imagined a positive event were more likely to report that they were approaching the event. Experiments 3a and 3b showed that participants judge an event to be more positive if it is described from the ego-moving perspective than if it is described from the time-moving perspective. Results from these studies provide initial evidence that positive and negative events are associated with different spatial metaphors of time. (shrink)

The existence of object-dependent thoughts has been doubted on the grounds that reference to such thoughts is unnecessary or 'redundant' in the psychological explanation of intentional action. This paper argues to the contrary that reference to object-dependent thoughts is necessary to the proper psychological explanation of intentional action upon objects. Section I sets out the argument for the alleged explanatory redundancy of object-dependent thoughts; an argument which turns on the coherence of an alternative 'dual-component' model of explanation. Section II rebuts (...) this argument by showing the dual-component model to be incoherent precisely because of its exclusion of object-dependent thoughts. Section III concludes with a conjecture about the further possible significance of object-dependent thoughts for the prediction of action. (shrink)

The character of potential threats becomes extremely important in evaluating the legitimacy of the new preemption doctrine, and thus the assertion that the United States faces rogue enemies who oppose everything about the United States must be carefully evaluated.

The received view in the history of the philosophy of psychology is that the logical positivists—Carnap and Hempel in particular—endorsed the position commonly known as “logical” or “analytical” behaviourism, according to which the relations between psychological statements and the physical-behavioural statements intended to give their meaning are analytic and knowable a priori. This chapter argues that this is sheer legend: most, if not all, such relations were viewed by the logical positivists as synthetic and knowable only a posteriori. It then (...) traces the origins of the legend to the logical positivists’ idiosyncratic extensional or at best weakly intensional use of what are now considered crucially strongly intensional semantic notions, such as “translation,” “meaning” and their cognates, focussing on a particular instance of this latter phenomenon, arguing that a conflation of explicit definition and analyticity may be the chief source of the legend.

The body image with respect to physical disability has long been a woefully under-theorized area of scholarship. The literature that does attend to the body image in cases of physical abnormality or functional impairment regularly offer poorly articulated or problematic definitions of the concept, effectively undermining its historic analytic scope and depth. Here, I revisit the epistemic roots of the body image while also engaging the rich contemporary literature from a body studies perspective in order to situate the narratives of (...) amputees about the relationship between dismemberment, prosthetization, phantom limb syndrome, and body image. Stories about living with artificial, fleshy, phantomed, and residual limbs unquestionably reveal a number of peculiarities unique to amputees. However, they also offer a distinctively productive ingress into the analytic utility of a ‘re-visioned’ conceptualization of the body image more broadly speaking. Indeed, the body image can function as a robust investigative tool for exploring the intersubjective, processual, and relational features of embodiment and corporeality. (shrink)

Several approaches to implementing symbol-like representations in neurally plausible models have been proposed. These approaches include binding through synchrony, “mesh” binding, and conjunctive binding. Recent theoretical work has suggested that most of these methods will not scale well, that is, that they cannot encode structured representations using any of the tens of thousands of terms in the adult lexicon without making implausible resource assumptions. Here, we empirically demonstrate that the biologically plausible structured representations employed in the Semantic Pointer Architecture approach (...) to modeling cognition do scale appropriately. Specifically, we construct a spiking neural network of about 2.5 million neurons that employs semantic pointers to successfully encode and decode the main lexical relations in WordNet, which has over 100,000 terms. In addition, we show that the same representations can be employed to construct recursively structured sentences consisting of arbitrary WordNet concepts, while preserving the original lexical structure. We argue that these results suggest that semantic pointers are uniquely well-suited to providing a biologically plausible account of the structured representations that underwrite human cognition.

‘@AP: Breaking: Two Explosions in the White House and Barack Obama is injured’. So read a tweet sent from a hacked Associated Press Twitter account @AP, which affected financial markets, wiping out $136.5 billion of the Standard & Poor’s 500 Index’s value. While the speed of the Associated Press hack crash event and the proprietary nature of the algorithms involved make it difficult to make causal claims about the relationship between social media and trading algorithms, we argue that it helps (...) us to critically examine the volatile connections between social media, financial markets, and third parties offering human and algorithmic analysis. By analyzing the commentaries of this event, we highlight two particular currents: one formed by computational processes that mine and analyze Twitter data, and the other being financial algorithms that make automated trades and steer the stock market. We build on sociology of finance together with media theory and focus on the work of Christian Marazzi, Gabriel Tarde and Tony Sampson to analyze the relationship between social media and financial markets. We argue that Twitter and social media are becoming more powerful forces, not just because they connect people or generate new modes of participation, but because they are connecting human communicative spaces to automated computational spaces in ways that are affectively contagious and highly volatile.

Aims: To describe individuals’ perceptions of the activities that take place within the cancer genetics clinic, the relationships between these activities and how these relationships are sustained. Design: Qualitative interview study. Participants: Forty individuals involved in carrying out cancer genetics research in either a clinical (n = 28) or research-only (n = 12) capacity in the UK. Findings: Interviewees perceive research and clinical practice in the subspecialty of cancer genetics as interdependent. The boundary between research and clinical practice is described (...) as vague or blurred, and this ambiguity is regarded as being sustained by a range of methodological, ethical and economic factors. The implications of these findings for the “therapeutic misconception” are explored. It is argued that while research participation is seen as having therapeutic benefit for individual patients, the interviewees are not labouring under any misconceptions about the relationship between research and clinical care. It is suggested that concepts such as the “therapeutic misconception” may have less relevance in highly technological specialities that are characterised by a developing evidence base. (shrink)

The simulation hypothesis claims that the whole observable universe, including us, is a computer simulation implemented by technologically advanced beings for an unknown purpose. The simulation argument (as I reconstruct it) is an argument for this hypothesis with moderately plausible premises. I develop two lines of objection to the simulation argument. The first takes the form of a structurally similar argument for a conflicting conclusion, the claim that I am a so-called freak observer, formed spontaneously in a quantum or thermodynamic (...) fluctuation rather than through ordinary processes of evolution and growth. The second rejects the basic line of reasoning of both arguments: the sort of evidence they cite is not capable of supporting either the claim that I am a simulant or the claim that I am a freak observer. The evidence that simulants or freak observers exist is not a reason to think that I am one of them. (shrink)

The paper presents a new theory of perceptual demonstrative thought, the property-dependent theory. It argues that the theory is superior to both the object-dependent theory (Evans, McDowell) and the object-independent theory (Burge).

Abstract According to Russellianism, the content of a Russellian thought, in which a person ascribes a monadic property to an object, can be represented as an ordered couple of the object and the property. A consequence of this is that it is not possible for a person to believe that a is F and not to believe b is F, when a=b. Many critics of Russellianism suppose that this is possible and thus that Russellianism is false. Several arguments for this (...) claim are criticized and it is argued that Russellians need not appeal to representational notions in order to defeat them. Contrary to popular opinion, the prospects for a pure Russellianism, a Russellianism without representations, are in fact very good. (shrink)

Among various case studies addressing the reception of relativity, very few deal with Portugal at either the international or the national level. The national literature on the topic has mainly concentrated on the reactions to relativity of the Portuguese mathematical community. The absence of Portuguese astronomers alongside Eddington during the 1919 expedition to Principe, then a Portuguese island, has been implicitly equated with the astronomical community's lack of interest in the event. In reception studies dealing with general relativity, analysis has (...) tended to focus on the physics and mathematics communities, less on the astronomers. Given that relativity was born at the interface of physics, mathematics and astronomy, reactions of members of these scientific communities depended on differences in shared traditions, values, problems and expectations, as well as on individual practitioners' idiosyncrasies. This paper addresses the contributions of the overlooked Portuguese astronomical community, evaluates the actions and reactions of its members to the expedition and assesses their role in the process of appropriation of relativity.
