This article is a rebuttal to Kevin Smith's ‘Against Homeopathy,’ which was posted on 14 February 2011.1 It contends that his argument rests entirely on the assumption that homeopathic remedies are nothing but placebos. His argumentation is good, but his assumption is false. Evidence is presented to show that the Law of Similars is plausible and that ultradilute remedies do indeed have biological activity.

This comprehensive study of probability considers the approaches of Pascal, Laplace, Poisson, and others. It also discusses Laws of Large Numbers, the theory of errors, and other relevant topics.

The teaching of evolution has always been a controversial issue in the United States. Despite the fact that evolution is accepted by biologists all over the world and the evidence is beyond dispute, the percentage of Americans who do not accept evolution hovers around 40%. (P.14) However, it's important to note that there are positive trends on the horizon. For example, the percentage of Americans under the age of 30 who accept evolution increases to about 68%. While several factors contribute (...) to this increase in acceptance and understanding, it's fair to say that improvements in science education have contributed to the increase. In order to continue this trend, it's essential that today's science teachers present their evolution lessons with confidence and a good depth of understanding. And since teachers are each other's best resources, this book offers to give science teachers a glimpse into the classrooms of effective evolution educators. In the book's foreword, one of the world's most imminent educators of science education, Dr. Richard Dawkins, offers his insights about evolution education in America. The chapters of twelve veteran science teachers follow. Each teacher shares their educational journeys, their insights, and their best practices in the hopes they can positively contribute to the scientific literacy of our nation. All of these teachers are members of the Teacher Institute for Evolutionary Science, TIES (www.tieseducation.org). Under the direction of its director, Bertha Vazquez, TIES has presented over 200 TIES workshops and webinars in all 50 US States in the last 6 years. The authors in this book are all TIES presenters. They represent the varied voices of America's evolution educators. The astounding success of TIES is a testament to the importance of teacher training in evolution education. It is our hope that this book contributes to this ongoing professional development. (shrink)

In a series of papers over the past twenty years, and in a new book, Igor Douven has argued that Bayesians are too quick to reject versions of inference to the best explanation that cannot be accommodated within their framework. In this paper, I survey their worries and attempt to answer them using a series of pragmatic and purely epistemic arguments that I take to show that Bayes’ Rule really is the only rational way to respond to your evidence.

Longtermism is the view that the most urgent global priorities, and those to which we should devote the largest portion of our resources, are those that focus on (i) ensuring a long future for humanity, and perhaps sentient or intelligent life more generally, and (ii) improving the quality of the lives that inhabit that long future. While it is by no means the only one, the argument most commonly given for this conclusion is that these interventions have greater expected goodness (...) per unit of resource devoted to them than each of the other available interventions, including those that focus on the health and well-being of the current population. In this paper, I argue that, even if we grant the consequentialist ethics upon which this argument depends, and even if we grant one of the axiologies that are typically paired with that ethics to give the argument, we are not morally required to choose an option that maximises expected utility; indeed, we might not even be permitted to do so. Instead, I will argue, if the argument's consequentialism is correct, we should choose using a decision theory that is sensitive to risk, and allows us to give greater weight to worse-case outcomes than expected utility theory does. And, I will show, such decision theories do not always recommend longtermist interventions. Indeed, sometimes, they recommend exactly the opposite: sometimes, they recommend hastening human extinction. Many, though not all, will take this as a reductio of the consequentialism or the axiology of the argument. I remain agnostic on the conclusion we should draw. (shrink)

One goal of this paper is to argue that autobiographical memories are extended and distributed across embodied brains and environmental resources. This is important because such distributed memories play a constitutive role in our narrative identity. So, some of the building blocks of our narrative identity are not brain-bound but extended and distributed. Recognising the distributed nature of memory and narrative identity, invites us to find treatments and strategies focusing on the environment in which dementia patients are situated. A second (...) goal of this paper is to suggest various of such strategies, including lifelogging technologies such as SenseCams, life story books, multimedia biographies, memory boxes, ambient intelligence systems, and virtual reality applications. Such technologies allow dementia patients to remember their personal past in a way that wouldn’t be possible by merely relying on their biological memory, in that way aiding in preserving their narrative identity and positively contributing to their sense of well-being.

Conservative assumptions in medical ethics risk immense harms during a pandemic. Public health institutions and public discourse alike have repeatedly privileged inaction over aggressive medical interventions to address the pandemic, perversely increasing population-wide risks while claiming to be guided by ‘caution’. This puzzling disconnect between rhetoric and reality is suggestive of an underlying philosophical confusion. In this paper, I argue that we have been misled by status quo bias—exaggerating the moral significance of the risks inherent in medical interventions, while systematically (...) neglecting the risks inherent in the status quo prospect of an out-of-control pandemic. By coming to appreciate the possibility and significance of status quo risk, we will be better prepared to respond appropriately when the next pandemic strikes. (shrink)

When the modern artist is seen as moving about in a nebulous area between two opposing worlds, that of life or immediate experience and that of art or established truth, I think it is appropriate to discuss this activity in terms of metaphor. Indeed the present concern for metaphor in the academic and artistic communities is but one of many reflections of our sense that life is a process of the gradual attainment of knowledge through experience, whether sensuous or intellectual. (...) Like our artists, we strive to create a picture of our world, yet that picture is never complete; for we continually pass on to new experiences and new images of reality. Not only do we grow and change but our world seems to change with us. Although the truths revealed through our art are founded in our experience, they seem more permanent and public than the acts of discovery leading to them. A principle once established and integrated with a body of other established truths enters into recorded history perhaps to be revered, disputed, or reinterpreted, but nevertheless to remain. The individual experience or discovery, however, passes; with the individual, only the sense of the continuing search yields personal identity. In a changing world, metaphor renders the truth of experience as the truth of knowledge, for it is the means of passing from individual immediacy to an established public world; the new must be linked to the old, and the experience of any individual must be connected with that of his society. Excluding the possibility of the creation of entirely new worlds and the resultant transformation of all personal identities, acts of genius or dramatic breakthroughs in fields of study can affect our present world order only if they are joined to it by means of a powerful metaphor. Indeed establishing the metaphoric bridge itself may be considered the act of genius, and the entry into new areas of knowledge is its consequence.

How should an impartial social observer judge distributions of well-being across different individuals when there is uncertainty regarding the state of the world? I explore this question by imposing very weak conditions of rationality and benevolent sympathy on impartial betterness judgments under uncertainty. Although weak enough to be consistent with all the main theories of rationality, these conditions prove to be sufficient to rule out any heterogeneity in what is good for individuals, to require a neutral attitude to uncertainty on (...) the part of the social observer, and to require that both individual and social betterness be strongly separable.

Rational choice models are characterized by the image of the self-interested Homo economicus. The role of moral concerns, which may involve a concern for others' welfare in people's judgments and choices, questions the descriptive validity of such models. Increasing evidence of a role for perceived moral obligation within the expectancy-value-based theory of reasoned action and the theory of planned behavior indicates the importance of moral-normative influences in social behavior. In 2 studies, the influence of moral judgments on attitudes toward food (...) produced with the use of genetic engineering techniques and toward meat consumption is addressed. The reasons participants provide for their moral judgments indicate some foci of their moral concerns. The results of both studies corroborate earlier findings that perceived moral obligation has independent effects on behavioral intentions; they also provide evidence that such judgments may affect attitudes themselves. The results are discussed in relation to the need for attitude-behavior models to reflect the role of moral evaluations in judgment and choice. (shrink)

RICHARD SHEDENHELM responds to Robert Campbell's essay, "Ayn Rand and the Cognitive Revolution in Psychology" . He identifies the most likely source of the crow-counting experiment cited at the beginning of chapter seven of Ayn Rand's Introduction to Objectivist Epistemology. He finds that the crow study was not at all an experiment, but instead an anecdotal account dating from the eighteenth-century French writer of animal behavior, Charles-Georges Leroy.

There are many reasons we might want to take the opinions of various individuals and pool them to give the opinions of the group they constitute. If all the individuals in the group have probabilistic opinions about the same propositions, there is a host of pooling functions we might deploy, such as linear or geometric pooling. However, there are also cases where different members of the group assign probabilities to different sets of propositions, which might overlap a lot, a little, (...) or not at all. There are far fewer proposals for how to proceed in these cases, and those there are have undesirable features. I begin by considering four proposals and arguing that they don't work. Then I'll describe my own proposal, which is intended to cover the situation in which we want to pool the individual opinions in order to ascribe an opinion to the group considered as an agent in its own right.

This Very Short Introduction explores the philosophical ideas and political theories of Hannah Arendt (1906-1975). As a survivor of the Holocaust, Arendt's life informed her work exploring the meaning and construction of power, evil, totalitarianism, and direct democracy. Through insightful readings of Arendt's best-known works, from The Origins of Totalitarianism (1951) to The Life of the Mind (1978), Dana Villa traces the importance of Arendt's ideas for today's reader. In so doing, Villa explains how Arendt gained world-wide fame with the (...) publication of Origins, and went on to have a distinguished career as a political theorist and public intellectual. A sometimes controversial figure, Arendt is now recognised as one of the most important political thinkers of the twentieth century and her works have become an acknowledged part of the Western canon of political theory and philosophy"--From the publisher.

BackgroundDespite its ubiquity in academic research, the phrase ‘ethical challenge(s)’ appears to lack an agreed definition. A lack of a definition risks introducing confusion or avoidable bias. Conceptual clarity is a key component of research, both theoretical and empirical. Using a rapid review methodology, we sought to review definitions of ‘ethical challenge(s)’ and closely related terms as used in current healthcare research literature.MethodsRapid review to identify peer-reviewed reports examining ‘ethical challenge(s)’ in any context, extracting data on definitions of ‘ethical challenge(s)’ (...) in use, and synonymous use of closely related terms in the general manuscript text. Data were analysed using content analysis. Four databases (MEDLINE, Philosopher’s Index, EMBASE, CINAHL) were searched from April 2016 to April 2021.Results393 records were screened, with 72 studies eligible and included: 53 empirical studies, 17 structured reviews and 2 review protocols. 12/72 (17%) contained an explicit definition of ‘ethical challenge(s), two of which were shared, resulting in 11 unique definitions. Within these 11 definitions, four approaches were identified: definition through concepts; reference to moral conflict, moral uncertainty or difficult choices; definition by participants; and challenges linked to emotional or moral distress. Each definition contained one or more of these approaches, but none contained all four. 68/72 (94%) included studies used terms closely related to synonymously refer to ‘ethical challenge(s)’ within their manuscript text, with 32 different terms identified and between one and eight different terms mentioned per study.ConclusionsOnly 12/72 studies contained an explicit definition of ‘ethical challenge(s)’, with significant variety in scope and complexity. This variation risks confusion and biasing data analysis and results, reducing confidence in research findings. Further work on establishing acceptable definitional content is needed to inform future bioethics research. (shrink)

In his essay “Painting Memories” , Michael Fried identifies memory as the privileged thematic that structures Charles Baudelaire’s Salon of 1846. But he then limits his investigation of this topic by focusing on the representation of “past” art, to the exclusion of the recollection of “past” experience. Fried thus isolates the theme of memory from the dialectic of life and art that characterizes its performance for Baudelaire. Such selective analysis not only reverses Baudelaire’s priorities but deflects his pointed comments on (...) modernity and naiveté, which in turn inform the example of Edouard Manet, Fried’s exemplary modernist painter. One wonders whether too much of Baudelaire and Manet is lost to this view. Perhaps the predilections of contemporary criticism have sanctioned Fried’s approach. For today we hesitate to ground art in experience, preferring to conceive of representations as signs fully engendered by and engendering other signs. Baudelaire was of a different mind; he lived through the dawning of our own age, but also in the fading light of another. He was heir to a tradition that regarded the forms of art as powerfully motivated by the experience of internalized ideas and sensations; for him, a master artist’s “signs” would appear more symbolic than allegorical, more immediate than mediated or distanced. As we deny artistic signs motivation in extralinguistic “experience,” we aggravate that perennial problem of origins which Fried himself invokes. It might be reformulated in this manner: all painting depends on a lineage of antecedent painting; yet, to succeed, a new work must transcend its filial bondage, as it compounds the effect of the “original” in its own originality. Vexation follows from this issue of the artistic source. Since memories of past art make possible the very creation of art, the creative event cannot assume priority over memory. And the matter of primordial memory, like the matter of an absolutely original art, is aporia. Fried does not pursue this matter ; but the question necessarily implies that both representations and memories, in constituting the “past,” must always be distanced. Distanced not from the present, which they enter and likewise constitute, but from those “original” experiential moments they purport to present. Richard Schiff is associate professor of art at the University of North Carolina at Chapel Hill. He is the author of Cézanne and the End of Impressionism: A Study of the Theory, Technique, and Critical Evaluation of Modern Art and is currently working on a study of modernism in relation to classicism and a related study of photographic realism. His previous contributions to Critical Inquiry are “Seeing Cézanne” , “Art and Life: A Metaphoric Relationship” , and, with Carl Pletsch, “History and Innovation”. (shrink)

Recent contributions to the philosophy of the social sciences have motivated ontological commitments using appeals to the social sciences (_naturalized_ social ontologies). These arguments rely on social scientific realism about the social sciences, the view that our social scientific theories are approximately true. I apply a distinction formulated in metaontology between ontologically loaded and unloaded meanings of existential quantification to argue that there is a pragmatic approach to naturalized social ontology that is minimally realist (it treats existence claims as true (...) or false) but that is ontologically austere. I argue that the extant arguments may be construed in terms of this pragmatic approach. The result is an approach to social ontology that is deflationist about naturalized social ontology. (shrink)

This chapter argues that Hobbes believed that we have to assent inwardly as well as outwardly to the determinations of the sovereign, unless—surprisingly—we adhere to the Jewish or Christian religions. In those cases, we have made a civil covenant with God which in some respects trumps the covenant we have made to erect our normal commonwealth. The significance of this, the author claims, is that it brings out clearly the fact that our civil sovereign is internally authoritative because otherwise there (...) would have been no need for Hobbes to argue that God’s internal authority over the Jew or Christian itself rests on a civil covenant.

When is it legitimate for a government to ‘nudge’ its citizens, in the sense described by Thaler and Sunstein (2008)? In their original work on the topic, Thaler and Sunstein developed the _‘as judged by themselves’ (or AJBT) test_ to answer this question (Thaler and Sunstein 2008, p. 5). In a recent paper, Paul and Sunstein (2019) raised a concern about this test: it often seems to give the wrong answer in cases in which we are nudged to make a (...) decision that leads to what Paul calls a _personally transformative experience_, that is, one that results in our values changing (Paul 2014). In those cases, the nudgee will judge the nudge to be legitimate after it has taken place, but only because their values have changed as a result of the nudge. In this paper, I take up the challenge of finding an alternative test. I draw on my _aggregate utility account_ of how to choose in the face of what Ullmann-Margalit (2006) calls _big decisions_, that is, decisions that lead to these personally transformative experiences (Pettigrew 2019, Chapters 6 and 7).

This paper describes an attempt to repurpose Kant’s a priori psychology as the architectural blueprint for a machine learning system. First, it describes the conditions that must be satisfied for the agent to achieve unity of experience: the intuitions must be connected, via binary relations, so as to satisfy various unity conditions. Second, it shows how the categories are derived within this model: the categories are pure unary predicates that are derived from the pure binary relations. Third, I describe how (...) Kant’s cognitive architecture has been implemented in a computer system (the Apperception Engine) and show in detail what it is like for the system to construct a unified experience from a sequence of raw sensory input.

The universal acceptance of atomism in physics and chemistry in the early 20th century went along with an altered view on the epistemic status of microphysical conjectures. Contrary to the prevalent understanding during the 19th century, on the new view unobservable objects could be ‘discovered’. It is argued in the present paper that this shift can be connected to the implicit integration of elements of meta-empirical theory assessment into the concept of theory confirmation.

Few philosophers have left a legacy like that of Gottfried Wilhelm Leibniz. He has been credited not only with inventing the differential calculus, but also with anticipating the basic ideas of modern logic, information science, and fractal geometry. He made important contributions to such diverse fields as jurisprudence, geology and etymology, while sketching designs for calculating machines, wind pumps, and submarines. But the common presentation of his philosophy as a kind of unworldly idealism is at odds with all this bustling (...) practical activity. In this book Richard. T. W. Arthur offers a fresh reading of Leibniz’s philosophy, clearly situating it in its scientific, political and theological contexts. He argues that Leibniz aimed to provide an improved foundation for the mechanical philosophy based on a new kind of universal language. His contributions to natural philosophy are an integral part of this programme, which his metaphysics, dynamics and organic philosophy were designed to support. Rather than denying that substances really exist in space and time, as the idealist reading proposes, Leibniz sought to provide a deeper understanding of substance and body, and a correct understanding of space as an order of situations and time as an order of successive things. This lively and approachable book will appeal to students of philosophy, as well as anyone seeking a stimulating introduction to Leibniz's thought and its continuing relevance. (shrink)

This paper clarifies the usage of Albert Hirschman’s categories of market behaviour as of exit and voice in debates about workplace democracy by taking seriously his critique of the neoclassical analysis of competition. Pro-market liberals are generally hostile to the idea of workplace democracy and tend to favour top-down hierarchies as a way of organising labour. This hostility is generally inspired by the neoclassical analysis of exploitation and efficiency, which leads them to defend distributions achieved through exit-based competitive equilibria. Following (...) Hirschman, I propose to consider a hypothetical alternative: a democratic equilibrium, reached through the use of voice. I show that it would present the same appealing characteristics than its competitive counterpart while also accounting for the non-ideal conditions in which markets operate. Support for free markets should entail support for workplace democracy minimally understood as a strengthening of voice. (shrink)

A significant body of evidence shows that law schools and many elite colleges use large admissions preferences based on race, and other evidence strongly suggests that large preferences can undermine student achievement in law school and undergraduate science majors, thus producing highly counterproductive effects. This article draws on available evidence to examine the use of racial preferences in medical school admissions, and finds strong reasons for concern about the effects and effectiveness of current affirmative action efforts. The author calls for (...) better data and careful investigation of several identified patterns. (shrink)

What is strange? Or better, who is strange? When do we encounter the strange? We encounter strangers when we are not at home: when we are in a foreign land or a foreign part of our own land. From Freud to Lacan to Kristeva to Heidegger, the feeling of strangeness--das Unheimlichkeit--has marked our encounter with the other, even the other within our self. Most philosophical attempts to understand the role of the Stranger, human or transcendent, have been limited to standard (...) epistemological problems of other minds, metaphysical substances, body/soul dualism and related issues of consciousness and cognition. This volume endeavors to take the question of hosting the stranger to the deeper level of embodied imagination and the senses. This volume plays host to a number of encounters with the strange. It asks such questions as: How does the embodied imagination relate to the Stranger in terms of hospitality or hostility? How do we distinguish between projections of fear or fascination, leading to either violence or welcome? How do humans "sense" the dimension of the strange and alien in different religions, arts, and cultures? How do the five physical senses relate to the spiritual senses, especially the famous "sixth" sense, as portals to an encounter with the Other? Is there a carnal perception of alterity, which would operate at an affective, prereflective, preconscious level? What exactly do "embodied imaginaries" of hospitality and hostility entail, and how do they operate in language, psychology, and social interrelations? And what, finally, are the topical implications of these questions for an ethics and practice of tolerance and peace? (shrink)

In a study drawing from both evolutionary biology and the social sciences, evidence and argument is assembled in support of the comprehensive appli- cation of selfish gene theory to the human population. With a focus on genes giving rise to characteristically-human cooperation (“cooperative genes”) in- volving language and theory of mind, one may situate a whole range of pat- terned behaviour—including celibacy and even slavery—otherwise seeming to present insuperable difficulties. Crucially, the behaviour which tends to propa- gate the cooperative genes (...) may be “at cost” to the genes of some who may be party to the cooperation itself. Explanatory insights are provided by Trivers’ parent-offspring conflict theory, Lack’s principle, and Hamilton’s kin selec- tion mechanism. A primary observation is that cooperation using language and theory of mind is itself interdependent with full human conceptualization of a world of objects and of themselves as embodied beings. Human capaci- ties inhering in, or arising out of, the ability to cooperate are also responsible for a vitally important long-term process, the domestication of animals and p- lants. The approach illuminates the difference between animal and human sexual behaviour, and the emergence of kinship systems. Again, recent pat- terns of population growth become much more explicable. It is argued that the gene is the single controlling replicator; the notion of the meme as a sec- ond independent replicator is flawed. (shrink)

The binary distinction De Neys questions has been put forward many times since the beginnings of psychology, in slightly different forms and under different names. It has proved enormously useful and has received detailed empirical support and careful modeling. At heart the distinction is that between knowledge in long-term memory and control processes in short-term memory.

This essay explores logical and physical readings of Spinoza’s Ethics. It argues that Spinoza made logic more like physics, rather than making physics into logic. A dichotomy between the metaphysical and physical is inappropriate in thinking about his work. One way to understand his approach is through quasi-Kantian terms, of making physics possible, although his work has left the question of what exists to those pursuing research to find out.
