During the 1960s, Howard M. Temin (1934-1994), dared to advocate a "heretical" hypothesis that appeared to be at variance with the central dogma of molecular biology, understood by many to imply that information transfer in nature occurred only from DNA to RNA. Temin's provirus hypothesis offered a simple explanation of both virus replication and viral-induced cancer and stated that Rous sarcoma virus, an RNA virus, is replicated via a DNA intermediate. Popular accounts of this scientific episode, written after the discovery (...) of an RNA-directed DNA polymerase in 1970, tend to describe the reaction to his proposition as ardent opposition. Typically these accounts use a 'molecular biology' standpoint emphasizing the central dogma's part in its rejection. In this article, however, this episode will be examined from a joint perspective of virology and experimental cancer research. From this perspective it is clear that Temin's work was well within the epistemological and methodological boundaries of virology and cancer research. Still, scientists did have reasons to doubt the provirus hypothesis, but these do not seem to be good enough to either justify an account that portrays Temin as a renegade or his ideas as heretical.

This paper follows the circuitous path of theories concerning the origins of viruses from the early years of the twentieth century until the present, considering RNA viruses in particular. I focus on three periods during which new understandings of the nature of viruses guided the construction and reconstruction of origin hypotheses. During the first part of the twentieth century, viruses were mostly viewed from within the framework of bacteriology and the discussion of origin centered on the “degenerative” or the “retrograde (...) evolution theory.” However, concomitantly, in the context of origin-of-life theorizing, the notion that viruses are vestiges of a prebiotic world was also being contemplated. In the 1960s the idea that viruses were genetic elements that “escaped” from cells became prevalent. These traditional hypotheses are being revisited nowadays by evolutionary virologists, who have placed them within a new conceptual framework that is supported by cutting-edge genomic and proteomic data. Two current, opposing scenarios of virus origin are presented. The philosophical dimensions of “revisiting” the original hypotheses are briefly discussed. (shrink)

This text offers an account of how philosophers in the 20th century have challenged the ideas of the modern philosophers of the 17th century on fundamental questions in epistemology. Featuring examples, self-study questions and further readings, the text introduces and critically defines logical analysis, foundationalism and coherentism.

Truthmaker monism is the view that the one and only truthmaker is the world. Despite its unpopularity, this view has recently received an admirable defence by Schaffer :307–324, 2010b). Its main defect, I argue, is that it omits partial truthmakers. If we omit partial truthmakers, we lose the intimate connection between a truth and its truthmaker. I further argue that the notion of a minimal truthmaker should be the key notion that plays the role of constraining ontology and that truthmaker (...) monism is not necessary for an appropriate solution to the problem of finding truthmakers for negative truths. I conclude that we should reject truthmaker monism once and for all. (shrink)

After 1989, capitalism has successfully presented itself as the only realistic political-economic system - a situation that the bank crisis of 2008, far from ending, actually compounded. The book analyses the development and principal features of this capitalist realism as a lived ideological framework. Using examples from politics, films, fiction, work and education, it argues that capitalist realism colours all areas of contemporary experience. But it will also show that, because of a number of inconsistencies and glitches internal to the (...) capitalist reality program capitalism in fact is anything but realistic. (shrink)

This new and expanded edition of The Logic of Real Arguments explains a distinctive method for analysing and evaluating arguments. It discusses many examples, ranging from newspaper articles to extracts from classic texts, and from easy passages to much more difficult ones. It shows students how to use the question 'What argument or evidence would justify me in believing P?', and also how to deal with suppositional arguments beginning with the phrase 'Suppose that X were the case.' It aims to (...) help students to think critically about the kind of sustained, theoretical arguments which they commonly encounter in the course of their studies, including arguments about the natural world, about society, about policy, and about philosophy. It will be valuable for students and their teachers in a wide range of disciplines including philosophy, law and the social sciences. (shrink)

The revival of analytic metaphysics in the latter half of the twentieth century is typically understood as a consequence of the critiques of logical positivism, Quine’s naturalization of ontology, Kripke’s Naming and Necessity, clarifications of modal notions in logic, and the theoretical exploitation of possible worlds. However, this explanation overlooks the work of metaphysicians at the height of positivism and linguisticism that affected metaphysics of the late twentieth century. Donald C. Williams is one such philosopher. In this paper I explain (...) how Williams’s fundamental ontology and philosophy of time influenced in part the early formation of David Lewis’s metaphysics. Thus, Williams played an important role in the revival of analytic metaphysics. (shrink)

Whether intended or not, conceptions of informed consent are often rooted in archetypal notions of the researcher and prospective study participant. The former is assumed problematically to be a disinterested yet humanitarian individual who is well trained to conduct robust science. The latter is often characterized as being motivated by some altruistic notions about the contribution to science and society they are making even as they seek some personal benefit from the research. Cast in a dyad, the researcher has the (...) responsibility to inform the participant thoroughly about the purpose of the research, the risks and benefits of participation, and any alternatives to research available, as well as the ..

It is controversial whether virtual reality should be considered fictional or real. Virtual fictionalists claim that objects and events within virtual reality are merely fictional: they are imagined and do not exist. Virtual realists argue that virtual objects and events really exist. This metaphysical debate might appear important for some of the practical questions that arise regarding how to morally evaluate and legally regulate virtual reality. For instance, one advantage claimed of virtual realism is that only by taking virtual objects (...) and events to be real can we explain our strong emotional reactions to certain virtual actions, as well as their potential immorality. This paper argues that emotional reactions towards, and wrongs within, virtual reality are consistent with its being merely fictional. The emotional and ethical judgments we wish to make regarding virtual reality do not provide any grounds for preferring virtual realism. (shrink)

This article surveys the latest research on risky-choice framing effects, focusing on the implications for rational decision-making. An influential program of psychological research suggests that people's judgements and decisions depend on the way in which information is presented, or ‘framed’. In a central choice paradigm, decision-makers seem to adopt different preferences, and different attitudes to risk, depending on whether the options specify the number of people who will be saved or the corresponding number who will die. It is standardly assumed (...) that such responses violate a foundational tenet of rational decision-making, known as the principle of description invariance. We discuss recent theoretical and empirical research that challenges the dominant ‘irrationalist’ narrative. These approaches typically pay close attention to how decision-makers represent decision problems (including their interpretation of numerical quantifiers or predicate choice) and they highlight the need for a more robust characterization of the description invariance principle. We conclude by indicating avenues for future research that could bring us closer to a complete—and potentially rationalizing—explanation of framing effects. (shrink)

In the middle of last century metaphysics was widely criticized, ridiculed, and committed to the flames. During this period a handful of philosophers, against several anti-metaphysical trends, defended metaphysics and articulated novel metaphysical doctrines. Donald C. Williams was one of these philosophers. But while his contributions to metaphysics are well known his defence of metaphysics is not and yet it played a key part in the development and revival of metaphysics. In this paper I present his defence of metaphysics in (...) its historical context. I also show how his defence is relevant in response to recent attacks on metaphysics. (shrink)

In the early twentieth century, many philosophers in America thought that time should be taken seriously in one way or another. George P. Adams (1882-1961) argued that the past, present and future are all real but only the present is actual. I call this theory ‘actualist eternalism’. In this paper, I articulate his novel brand of eternalism as one piece of his metaphysical system and I explain how he argued for the view in light of the best explanations of temporal (...) experience and the present. I argue that his exploitation of analogies between time and modality offer some lessons for current debates about time such as the importance of providing a temporal epistemology. I also extract what I call the temporal boundary problem and argue that it gives rise to an unaddressed challenge for presentists and growing block theorists. (shrink)

Phase I clinical trials are the first stage of testing new pharmaceuticals in humans. The majority of these studies are conducted under controlled, inpatient conditions using healthy volunteers who are paid for their participation. This article draws on an ethnographic study of six phase I clinics in the United States, including 268 semistructured interviews with research staff and healthy volunteers. In it, I argue that an institutional banalization of risk structures the perceptions of research staff and healthy volunteers participating in (...) the studies. For research staff, there are three mechanisms by which risk becomes banal: a perceived homogeneity of studies, Fordist work regimes, and data-centric discourse. For healthy volunteers, repeat study participation contributes to the institutional banalization of risk both through the process of desensitization to risk and the formation of trust in the clinics. I argue that the institutional banalization of risk also renders invisible ethical concerns about exploitation of underprivileged groups in pharmaceutical research. (shrink)

Central issues in philosophy of architecture include foundational matters regarding the nature of: (1) architecture as an artform, design medium, or other product or practice; (2) architectural objects—what sorts of things they are; how they differ from other sorts of objects; and how we define the range of such objects; (3) special architectural properties, like the standard trio of structural integrity (firmitas), beauty, and utility—or space, light, and form; and ways they might be special to architecture; (4) architectural types—how to (...) consider abstract groups of architectural objects and their instances; (5) meaning and other language-like phenomena in architecture and its objects; (6) formation of and warrant for our basic grasp, and considered judgment, of architectural objects; and (7) social and moral features of architectural objects and architectural practice. Yet other questions engage applied philosophical concerns regarding architecture, such as the character of architectural notation; intellectual property rights; and client-architect obligations. A far-reaching philosophy of architecture extends beyond even a broadly aesthetics-based assessment, to include considerations of ethics, social and political philosophy, and philosophical reflections on psychology and the behavioral sciences. The aesthetics of architecture, by itself, spans traditional issues mooted in philosophy of art, as well as aesthetics of the everyday, and environmental aesthetics. Such traditional issues include the nature of the work; the possibility of classes, kinds, or types in the domain; the character and roles of representation, intentionality, and expression; and the warranted foundations for criticism. The ethics of architecture also addresses traditional issues, including delineation of rights, responsibilities, the good, virtues, and justice in architectural milieus. Still other aspects of philosophy of architecture concern social and technological characteristics. (shrink)

David Lewis is widely known for maintaining the bizarre thesis known as genuine modal realism (hereafter, modal realism). He argued for modal realism on grounds of serviceability in On the Plurality of Worlds. However, earlier in Counterfactuals, he proposed a different kind of argument: from talk of ways things might be to possible worlds. In this paper, I examine the evolution of the latter argument in Lewis’s thought and evaluate its place in his overall case for modal realism, especially in (...) light of the alternative theory of modality known as magical ersatzism. I argue that Lewis turns the argument on its head in his critique of magical ersatzism, but that his later commitment to Ramseyan humility subjects him to a similar criticism. Therefore, the argument is, ultimately, a poisoned pawn for Lewis. (shrink)

A number of authors have suggested that a conditional analysis of dispositions must take roughly the following form: Thing X is disposed to produce response R to stimulus S just in case, if X were exposed to S and surrounding circumstances were auspicious, then X would produce R. The great challenge is cashing out the relevant notion of ‘auspicious circumstances’. I give a general argument which entails that all existing conditional analyses fail, and that there is no satisfactory way to (...) define ‘auspicious circumstances’ just in terms of S, R, and X. Instead, I argue that the auspicious circumstances C for the manifestation of a disposition constitute a third irreducible element of that disposition, and that to pick out (or to ‘individuate’) that disposition one must specify C along with S and R. This enables a new conditional analysis of dispositions that gives intuitively satisfying answers in cases that pose problems for other approaches. (shrink)

This paper contributes to an ongoing debate regarding the cognitive processes involved when one person predicts a target person's behavior and/or attributes a mental state to that target person. According to simulation theory, a person typically performs these tasks by employing some part of her brain as a simulation of what is going on in a corresponding part of the brain of the target person. I propose a general intuitive analysis of what 'simulation' means. Simulation is a particular way of (...) using one process to acquire knowledge about another process. What distinguishes simulation from other ways of acquiring knowledge is that simulation requires, for its non-accidental success, that the simulating process reflect significant aspects of the simulated process. This conceptual work is of independent philosophical interest, but it also enables me to argue for two conclusions that are of great significance to the debate about mental simulation theory. First, I argue that, in order to stake a non-trivial claim, simulation theory must hold that mental simulation involves what I call concretely similar processes. Second, I argue for the surprising conclusion that a significant class of cases that simulation theorists have claimed as intuitive cases of simulation do not actually involve simulation, after all. I close by sketching an alternative account that might handle these problematic cases. (shrink)

There has been considerable interest in the literature about how professions operate in both the private and public interest. This paper examines this issue in the context of the enforcement of the professional code of conduct of a particular professional accounting association. The paper explores whether certain enforcement actions of the association suggest behaviour motivated at least partially by private interest. It then considers whether the consequences of such behaviour or practices are troubling.

Social theory plays an important role in the nursing discipline and nursing inquiry as it helps conceptually embed nursing in the larger picture of the social world. For example, a broad category of critical theory provides a unique lens for uncovering social conditions of inequity and oppression. Among the sociological theories, actor‐network theory (ANT) is an approach to research and analysis that has recently gained interest among nurse philosophers and researchers. Studies guided by ANT seek to understand phenomena of interest (...) as constituted within the relationships between human and nonhuman actors to understand how care practices are co‐created/enacted and how they can be made more humane. In this paper, we describe the benefits of ANT for examining healthcare access for incarcerated individuals with life‐limiting illnesses accessing palliative care and for people using illicit drugs. We argue that attention to the materiality of care practices can contribute to efforts of advancing health equity for these groups. (shrink)

Recent studies indicate that patients who are diagnosed with vegetative states may retain more awareness than their clinical assessments suggest. Disorders of consciousness traditionally have been diagnosed on the basis of outwardly observable behaviors alone, but new functional imaging studies have shown surprising levels of brain activity in some patients, indicating that even higher-level cognitive functions like language processing and visual imagery may be preserved. For example, one recently developed method purports to detect voluntary mental imagery solely on the basis (...) of neural response patterns observed with functional magnetic resonance imaging. This line of research has already led to some widely reported cases of patients who were discovered to have more brain activity than expected. In November 2009, Rom Houben, a Belgian man who was thought to be in a coma for 23 years, was diagnosed with locked-in syndrome through the use of neuroimaging; however, that assessment was later overturned by further testing.

This chapter explores the philosophical development of Alexander’s empiricism, interest in experimental psychology, and its connection to realism and its subsequent rise in the early twentieth century. His early interests are most notably his rejection of British idealism and an empiricist tendency derived in part from classical empiricism and empirical developments in psychology. It is argued that Alexander arrives at realism through his work on psychology, thus revealing that the rise of realism has some psychological origins. His philosophical method is (...) also analysed in detail and it is shown that many of his arguments should be understood as following this method and that many objections to his arguments for realism and against his theory of perception can be resisted when this method is taken into consideration.

: This paper provides a simultaneously reflexive and analytical framework to think about obstacles to truly informed consent in social science and biomedical research. To do so, it argues that informed consent often goes awry due to procedural misconceptions built into the research context. The concept of procedural misconception is introduced to describe how individuals respond to what is familiar in research settings and overlook what is different. In the context of biomedical research, procedural misconceptions can be seen to function (...) as root causes of therapeutic misconceptions. (shrink)

Mental internalists hold that an individuals mental features at a given time supervene upon what is in that individuals head at that time. While many people reject mental internalism about content and justification, mental internalism is commonly accepted regarding such other mental features as rationality, emotion-types, propositional-attitude-types, moral character, and phenomenology. I construct a counter-example to mental internalism regarding all these features. My counter-example involves two creatures: a human and an alien from Pulse World. These creatures environments, behavioral dispositions and (...) histories are such that it is intuitively clear that they are mentally quite different, even while they are, for a moment, exactly alike with respect to whats in their heads. I offer positive reasons for thinking that the case I describe is indeed possible. I then consider ways in which mental internalists might attempt to account for this case, but conclude that the only plausible option is to reject mental internalism and to adopt a particular externalist alternative a history-oriented version of teleo-functionalism.

This paper explores what Epictetus thinks we need to learn in order to acquire the art of living, and, in doing so, illuminates the central tenets of Epictetus’ epistemology. It argues that we need to have cognition of preconceptions–innate, self-evident, general, ethical truths–and we need to know how to apply them. We acquire this “know-how” through habituation and, with it, are able to have cognition of correct applications.

That science is more than the unilinear application of general theories to specific empirical circumstances is, one hopes, no longer something that is controversial or requires detailed argument. To be sure, there were times when devising universally applicable theories was seen as the most worthy task of science, with less lofty activities such as experimentation and scientific modeling being relegated to the underbelly of “proper science.” Arguing for a pluralistic recognition of the diversity of scientific practices, methods, and goals, might—at (...) least on the pages of this journal—amount to preaching to the converted. Yet, once the diversity and heterogeneity of science is acknowledged, the real work only starts:... (shrink)

Researchers studying at-risk and socially disenfranchised child and adolescent populations are facing ethical dilemmas not previously encountered in the laboratory or the clinic. One such set of ethical challenges involves whether to: (a) share with guardians research derived information regarding participant risk, (b) provide participants with service referrals, or (c) report to local authorities problems uncovered during the course of investigation. The articles assembled for this special section address the complex issues of deciding if, when, and how to report or (...) provide referrals for research participants who are minors (referred to hereafter as minor research participants). This paper focuses on two factors underlying these decisions: the validity of risk estimates and meta-ethical positions on scientific responsibility. It is suggested that, before sharing information about minor research participants investigators should do the following: critically examine the diagnostic validity of developmental measures, include the scope and limitations of information sharing in informed consent procedures, and become familiar with state reporting laws. I discuss the impact of the traditionally accepted act utilitarian meta-ethical position on the investigator-participant relationship, and I recommend consideration of alternative positions as a step toward developing a research ethic of scientific responsibility and care.

This paper provides an account of truth in interactive fiction. Interactive fiction allows the audience to make choices, resulting in many different possible fictions within each interactive fiction, unlike in literary fiction where there is just one. Adequately capturing this feature of interactive fiction requires us to address familiar issues regarding impossible fiction and the nature of time in fiction. Truth in interactive fiction thus requires a complex account to capture its multitude of fictions. It is argued that a full (...) account of truth in interactive fiction requires distinguishing two works for each interactive fiction, which contain distinct fictional truths. The actual work encompasses what is in fact represented as fictional (hence mistakes can be fictionally true in this work), whilst in the implied work, truth in fiction is governed by authorial intention, hence mistakes are not fictionally true. This dual account best captures our aesthetic evaluation of interactive fictions, for which we often need to distinguish how the work actually is from how it was intended to be. (shrink)
