The inflation of Type I error rates is thought to be one of the causes of the replication crisis. Questionable research practices such as p-hacking are thought to inflate Type I error rates above their nominal level, leading to unexpectedly high levels of false positives in the literature and, consequently, unexpectedly low replication rates. In this article, I offer an alternative view. I argue that questionable and other research practices do not usually inflate relevant Type I error rates. I begin (...) by introducing the concept of Type I error rates and distinguishing between statistical errors and theoretical errors. I then illustrate my argument with respect to model misspecification, multiple testing, selective inference, forking paths, exploratory analyses, p-hacking, optional stopping, double dipping, and HARKing. In each case, I demonstrate that relevant Type I error rates are not usually inflated above their nominal level, and in the rare cases that they are, the inflation is easily identified and resolved. I conclude that the replication crisis may be explained, at least in part, by researchers’ misinterpretation of statistical errors and their underestimation of theoretical errors. (shrink)

One justification for preregistering research hypotheses, methods, and analyses is that it improves the transparent evaluation of the severity of hypothesis tests. In this article, I consider two cases in which preregistration does not improve this evaluation. First, I argue that, although preregistration can facilitate the transparent evaluation of severity in Mayo’s error statistical philosophy of science, it does not facilitate this evaluation in Popper’s theory-centric approach. To illustrate, I show that associated concerns about Type I error rate inflation are (...) only relevant in the error statistical approach and not in a theory-centric approach. Second, I argue that a preregistered test procedure that allows deviations in its implementation does not provide a more transparent evaluation of Mayoian severity than a non-preregistered procedure. In particular, I argue that sample-based validity-enhancing deviations cause an unknown inflation of the test procedure’s Type I (familywise) error rate and, consequently, an unknown reduction in its capability to license inferences severely. I conclude that preregistration does not improve the transparent evaluation of severity in Popper’s philosophy of science or when deviations are allowed. (shrink)

During multiple testing, researchers often adjust their alpha level to control the familywise error rate for a statistical inference about a joint union alternative hypothesis (e.g., “H1,1 or H1,2”). However, in some cases, they do not make this inference. Instead, they make separate inferences about each of the individual hypotheses that comprise the joint hypothesis (e.g., H1,1 and H1,2). For example, a researcher might use a Bonferroni correction to adjust their alpha level from the conventional level of 0.050 to 0.025 (...) when testing H1,1 and H1,2, find a significant result for H1,1 (p < 0.025) and not for H1,2 (p > .0.025), and so claim support for H1,1 and not for H1,2. However, these separate individual inferences do not require an alpha adjustment. Only a statistical inference about the union alternative hypothesis “H1,1 or H1,2” requires an alpha adjustment because it is based on “at least one” significant result among the two tests, and so it refers to the familywise error rate. Hence, an inconsistent correction occurs when a researcher corrects their alpha level during multiple testing but does not make an inference about a union alternative hypothesis. In the present article, I discuss this inconsistent correction problem, including its reduction in statistical power for tests of individual hypotheses and its potential causes vis-à-vis error rate confusions and the alpha adjustment ritual. I also provide three illustrations of inconsistent corrections from recent psychology studies. I conclude that inconsistent corrections represent a symptom of statisticism, and I call for a more nuanced inference-based approach to multiple testing corrections. (shrink)

Kerr coined the term ‘HARKing’ to refer to the practice of ‘hypothesizing after the results are known’. This questionable research practice has received increased attention in recent years because it is thought to have contributed to low replication rates in science. The present article discusses the concept of HARKing from a philosophical standpoint and then undertakes a critical review of Kerr’s twelve potential costs of HARKing. It is argued that these potential costs are either misconceived, misattributed to HARKing, lacking evidence, (...) or that they do not take into account pre- and post-publication peer review and public availability to research materials and data. It is concluded that it is premature to conclude that HARKing has led to low replication rates. (shrink)

Scientists often adjust their significance threshold during null hypothesis significance testing in order to take into account multiple testing and multiple comparisons. This alpha adjustment has become particularly relevant in the context of the replication crisis in science. The present article considers the conditions in which this alpha adjustment is appropriate and the conditions in which it is inappropriate. A distinction is drawn between three types of multiple testing: disjunction testing, conjunction testing, and individual testing. It is argued that alpha (...) adjustment is only appropriate in the case of disjunction testing, in which at least one test result must be significant in order to reject the associated joint null hypothesis. Alpha adjustment is inappropriate in the case of conjunction testing, in which all relevant results must be significant in order to reject the joint null hypothesis. Alpha adjustment is also inappropriate in the case of individual testing, in which each individual result must be significant in order to reject each associated individual null hypothesis. The conditions under which each of these three types of multiple testing is warranted are examined. It is concluded that researchers should not automatically assume that alpha adjustment is necessary during multiple testing. Illustrations are provided in relation to joint studywise hypotheses and joint multiway ANOVAwise hypotheses. (shrink)

The replication crisis has caused researchers to distinguish between exact replications, which duplicate all aspects of a study that could potentially affect the results, and direct replications, which duplicate only those aspects of the study that are thought to be theoretically essential to reproduce the original effect. The replication crisis has also prompted researchers to think more carefully about the possibility of making Type I errors when rejecting null hypotheses. In this context, the present article considers the utility of two (...) types of Type I error probability: the Neyman–Pearson long run Type I error rate and the Fisherian sample-specific Type I error probability. It is argued that the Neyman–Pearson Type I error rate is inapplicable in social science because it refers to a long run of exact replications, and social science deals with irreversible units that make exact replications impossible. Instead, the Fisherian sample-specific Type I error probability is recommended as a more meaningful way to conceptualize false positive results in social science because it can be applied to each sample-specific decision about rejecting the same substantive null hypothesis in a series of direct replications. It is concluded that the replication crisis may be partly due to researchers’ unrealistic expectations about replicability based on their consideration of the Neyman–Pearson Type I error rate across a long run of exact replications.

Preregistration has been proposed as a useful method for making a publicly verifiable distinction between confirmatory hypothesis tests, which involve planned tests of ante hoc hypotheses, and exploratory hypothesis tests, which involve unplanned tests of post hoc hypotheses. This distinction is thought to be important because it has been proposed that confirmatory hypothesis tests provide more compelling results (less uncertain, less tentative, less open to bias) than exploratory hypothesis tests. In this article, we challenge this proposition and argue that there (...) are several advantages of exploratory hypothesis tests that can make their results more compelling than those of confirmatory hypothesis tests. We also consider some potential disadvantages of exploratory hypothesis tests and conclude that their advantages can outweigh the disadvantages. We conclude that exploratory hypothesis tests avoid researcher commitment and researcher prophecy biases, reduce the probability of data fraud, are more appropriate in the context of unplanned deviations, facilitate inference to the best explanation, and allow peer reviewers to make additional contributions at the data analysis stage. In contrast, confirmatory hypothesis tests may lead to an inappropriate level of confidence in research conclusions, less appropriate analyses in the context of unplanned deviations, and greater bias and errors in theoretical inferences.

Several researchers have recently argued that p values lose their meaning in exploratory analyses due to an unknown inflation of the alpha level (e.g., Nosek & Lakens, 2014; Wagenmakers, 2016). For this argument to be tenable, the familywise error rate must be defined in relation to the number of hypotheses that are tested in the same study or article. Under this conceptualization, the familywise error rate is usually unknowable in exploratory analyses because it is usually unclear how many hypotheses have (...) been tested on a spontaneous basis and then omitted from the final research report. In the present article, I argue that it is inappropriate to conceptualize the familywise error rate in relation to the number of hypotheses that are tested. Instead, it is more appropriate to conceptualize familywise error in relation to the number of different tests that are conducted on the same null hypothesis in the same study. Under this conceptualization, alpha level adjustments in exploratory analyses are (a) less necessary and (b) objectively verifiable. As a result, p values do not lose their meaning in exploratory analyses. (shrink)

Fisher criticised the Neyman-Pearson approach to hypothesis testing by arguing that it relies on the assumption of “repeated sampling from the same population.” The present article considers the responses to this criticism provided by Pearson and Neyman. Pearson interpreted alpha levels in relation to imaginary replications of the original test. This interpretation is appropriate when test users are sure that their replications will be equivalent to one another. However, by definition, scientific researchers do not possess sufficient knowledge about the relevant (...) and irrelevant aspects of their tests and populations to be sure that their replications will be equivalent to one another. Pearson also interpreted the alpha level as a personal rule that guides researchers’ behavior during hypothesis testing. However, this interpretation fails to acknowledge that the same researcher may use different alpha levels in different testing situations. Addressing this problem, Neyman proposed that the average alpha level adopted by a particular researcher can be viewed as an indicator of that researcher’s typical Type I error rate. Researchers’ average alpha levels may be informative from a metascientific perspective. However, they are not useful from a scientific perspective. Scientists are more concerned with the error rates of specific tests of specific hypotheses, rather than the error rates of their colleagues. It is concluded that neither Neyman nor Pearson adequately rebutted Fisher’s “repeated sampling” criticism. Fisher’s significance testing approach is briefly considered as an alternative to the Neyman-Pearson approach. (shrink)

Hypothesizing after the results are known, or HARKing, occurs when researchers check their research results and then add or remove hypotheses on the basis of those results without acknowledging this process in their research report (Kerr, 1998). In the present article, I discuss three forms of HARKing: (1) using current results to construct post hoc hypotheses that are then reported as if they were a priori hypotheses; (2) retrieving hypotheses from a post hoc literature search and reporting them as a (...) priori hypotheses; and (3) failing to report a priori hypotheses that are unsupported by the current results. These three types of HARKing are often characterized as being bad for science and a potential cause of the current replication crisis. In the present article, I use insights from the philosophy of science to present a more nuanced view. Specifically, I identify the conditions under which each of these three types of HARKing is most and least likely to be bad for science. I conclude with a brief discussion about the ethics of each type of HARKing. (shrink)

O artigo analisa a leitura crítica de Hans Kelsen acerca da concepção jurídico-política de Thomas Hobbes, considerando críticas posteriores à própria interpretação de Kelsen. Para tanto, investigou-se primeiramente a posição de Kelsen sobre o jusnaturalismo buscando esclarecer conceitos centrais como os do ser e dever-ser e como o autor os associa a Hobbes. Nesse sentido, observouse a limitação da leitura de Kelsen em relação à filosofia jurídica do autor – uma doutrina jusnaturalista metafísica, tendo na regra de ouro o fundamento (...) natural para o direito positivo. Em contraposição, procurou-se apresentar uma postura crítica, que contesta a posição jusnaturalista atribuída a Hobbes e sustenta a tese de que o autor inglês é um precursor do positivismo jurídico.

Gelman and Loken (2013, 2014) proposed that when researchers base their statistical analyses on the idiosyncratic characteristics of a specific sample (e.g., a nonlinear transformation of a variable because it is skewed), they open up alternative analysis paths in potential replications of their study that are based on different samples (i.e., no transformation of the variable because it is not skewed). These alternative analysis paths count as additional (multiple) tests and, consequently, they increase the probability of making a Type I (...) error during hypothesis testing. The present article considers this forking paths problem and evaluates four potential solutions that might be used in psychology and other fields: (a) adjusting the prespecified alpha level, (b) preregistration, (c) sensitivity analyses, and (d) abandoning the Neyman-Pearson approach. It is concluded that although preregistration and sensitivity analyses are effective solutions to p-hacking, they are ineffective against result-neutral forking paths, such as those caused by transforming data. Conversely, although adjusting the alpha level cannot address p-hacking, it can be effective for result-neutral forking paths. Finally, abandoning the Neyman-Pearson approach represents a further solution to the forking paths problem. (shrink)

This article is featured in a special issue dedicated to theme, "the human being in the digital era: awareness, critical thinking and political space in the age of the internet and artificial intelligence." In this article, I consider the way that social-media companies nudge us to spend more time on their platforms, and I argue that, in principle, these nudges are morally permissible: they are not manipulative and do not violate any obvious moral rules. The moral problem, I argue, is (...) not with nudging in principle but is instead with the fact that users are being nudged towards something bad for them. In practice, this often involves being nudged to spend an unhealthy amount of time using a social-media app or being nudged towards content that is bad for us, such as by promoting eating-disorder content to young girls. Since nudging is morally permissible, it is open to these companies to use the same technologies to nudge us towards the good. (shrink)

Metascientists have studied questionable research practices in science. The present article considers the parallel concept of questionable metascience practices (QMPs). A QMP is a research practice, assumption, or perspective that has been questioned by several commentators as being potentially problematic for metascience and/or the science reform movement. The present article reviews ten QMPs that relate to criticism, replication, bias, generalization, and the characterization of science. Specifically, the following QMPs are considered: (1) rejecting or ignoring self-criticism; (2) a fast ‘n’ bropen (...) scientific criticism style; (3) overplaying the role of replication in science; (4) assuming a replication rate is “too low” without specifying an “acceptable” rate; (5) an unacknowledged metabias towards explaining the replication crisis in terms of researcher bias; (6) assuming that researcher bias can be reduced; (7) devaluing exploratory results as being more “tentative” than confirmatory results; (8) presuming that questionable research practices are problematic research practices; (9) focusing on knowledge accumulation; and (10) focusing on specific scientific methods. It is stressed that only some metascientists engage in some QMPs some of the time, and that these QMPs may not always be problematic. Research is required to estimate the prevalence and impact of QMPs. In the meantime, QMPs should be viewed as invitations to ask questions about how we go about doing better metascience. (shrink)

This paper concerns Plato’s characterization of the body as the soul’s tool. I take perception as an example of the body’s usefulness. I explore the Timaeus’ view that perception provides us with models of orderliness. Then, I argue that perception of confusing sensible objects is necessary for our cognitive development too. Lastly, I consider the instrumentality relationship more generally and its place in Plato’s teleological worldview.

On January 30, 2020, the World Health Organization declared a Public Health Emergency of International Concern (PHEIC) over what would quickly become known as SARS-CoV- 2 or COVID- 19. This emergency status was officially ended in the United States in May 2023 amidst much dissent and debate. Although emergency conditions resulting from COVID- 19 will likely wax and wane over the coming years, there is good reason to think that the incidence of severe global pandemics will increase over the next (...) century, as will declarations of emergency. The declaration of an emergency calls for urgent action, but it just as urgently demands careful reflection. Official “emergency” status licenses unparalleled executive intervention, completely reorganizing the lives of those who live under its decree. Such official recognition, however, is heavily dependent on the social context in and from which the emergency arises. Highlighting which circumstances rise to the level of an official emergency clarifies our reigning assumptions about what threshold of active harm—and in relation to which groups of people—demands immediate intervention.

I argue that the blameworthy deserve to suffer in that they deserve to feel guilt, which is the unpleasant experience of appreciating one’s apparent culpability for having done wrong. I argue that the blameworthy deserve to feel guilt because they owe it to those whom they’ve culpably wronged to (a) hold themselves accountable, (b) manifest the proper regard for those whom they’ve wronged, and (c) appreciate their culpability for, and the moral significance of, their wrongdoing. And I argue that the (...) blameworthy must feel guilt to satisfy a–c. What’s more, I argue that, in thinking about whether the blameworthy deserve to feel guilt, we need to compare the world in which the blameworthy feel guilt to the world in which the non-blameworthy feel guilt, for, as I argue, it’s insufficient to compare only the world in which the blameworthy feel guilt to the world in which the blameworthy don’t feel guilt.

Popper’s (1983, 2002) philosophy of science has enjoyed something of a renaissance in the wake of the replication crisis, offering a philosophical basis for the ensuing science reform movement. However, adherence to Popper’s approach may also be at least partly responsible for the sense of “crisis” that has developed following multiple unexpected replication failures. In this article, I contrast Popper’s approach with Lakatos’ (1978) approach and a related approach called naïve methodological falsificationism (NMF; Lakatos, 1978). The Popperian approach is powerful (...) because it is based on logical refutation, but its theories are noncausal and, therefore, lacking in scientific value. In contrast, the Lakatosian approach considers causal theories, but it concedes that these theories are not logically refutable. Finally, the NMF approach subjects Lakatosian causal theories to Popperian logical refutations. However, its approach of temporarily accepting a ceteris paribus clause during theory testing may be viewed as scientifically inappropriate, epistemically inconsistent, and “completely redundant” (Lakatos, 1978, p. 40). I conclude that the replication “crisis” makes the most sense in the context of the Popperian and NMF approaches because it is only in these two approaches that replication failures represent logical refutations of theories. In contrast, replication failures are less problematic in the Lakatosian approach because they do not logically refute theories. Indeed, in the Lakatosian approach, replication failures can be legitimately ignored or used to motivate theory development. (shrink)

In preparation for examining the place of introspective evidence in scientific psychology, the chapter begins by clarifying what introspection has been supposed to show, and why some concluded that it couldn't deliver. This requires a brief excursus into the various uses to which introspection was supposed to have been put by philosophers and psychologists in the modern period, together with a summary of objections. It then reconstructs some actual uses of introspection (or related techniques, differently monikered) in the early days (...) of experimental psychology. It distinguishes broader and narrower conceptions of introspection and argues that recent critics have tended to misdescribe how introspection was supposed to work. Drawing upon the broader conception of introspection, it argues that introspective reports are ineliminable in perceptual psychology. It concludes with some examples of such ineliminable uses of introspective reports in both earlier and recent perceptual psychology. (shrink)

Psychology considered as a natural science began as Aristotelian "physics" or "natural philosophy" of the soul, conceived as an animating power that included vital, sensory, and rational functions. C. Wolff restricted the term " psychology " to sensory, cognitive, and volitional functions and placed the science under metaphysics, coordinate with cosmology. Near the middle of the eighteenth century, Krueger, Godart, and Bonnet proposed approaching the mind with the techniques of the new natural science. At nearly the same time, Scottish thinkers (...) placed psychology within moral philosophy, but distinguished its "physical" laws from properly moral laws. British and French visual theorists developed mathematically precise theories of size and distance perception; they created instruments to test these theories and to measure visual phenomena such as the duration of visual impressions. By the end of the century there was a flourishing discipline of empirical psychology in Germany, with a professorship, textbooks, and journals. The practitioners of empirical psychology at this time typically were dualists who included mental phenomena within nature. Accordingly, psychology as a natural scientific disciplines was not invented in the 18th and 19th centuries, but *remade* from the extant empirical psychology. (shrink)

Pretendeu-se estudar a aquisição da virtude em Aristóteles a partir da interpretação de M. F. Burnyeat. Para esse, a virtude aristotélica exige dimensões cognitivas e emocionais, sendo que ao aprendiz não basta conhecer os princípios e as regras gerais da ação, mas deve ter internalizado, através do hábito, uma vontade de praticar ações nobres e justas. Compete ao sujeito virtuoso, portanto, ter o conhecimento do que é correto (the that), assim como, subsidiariamente, a justificativa do porquê é apropriada determinada ação (...) (the because). Da análise dessas variáveis, o autor procura esclarecer a figura conflituosa do akratic (incontinente) e do akalastos (perverso) e elucidar a hipótese do desenvolvimento moral. Concomitantemente este artigo pretende introduzir o problema criminológico da ideia de ressocialização ou da pena capital, entendendo ser o argumento aristotélico ainda influente para a filosofia da virtude e jurídica hodierna e necessário quando se discutem novos paradigmas éticos e jurídicos.

O presente artigo aborda o problema da soberania para Hans Kelsen. Tem como objetivo analisar a posição do autor sobre o tema (especialmente através do texto Sovereignty), traçando paralelamente algumas considerações. Ocorre que para Kelsen o conceito de soberania mostra-se impreciso a partir da doutrina tradicional. Ainda, mesmo superando essa doutrina e a teoria dualista, também o conteúdo do direito nacional e internacional permanece inalterado. Portanto, prova-se a irrelevância de tal para a teoria jurídica.

O artigo tem como objetivo apresentar o problema da determinação do sentido das normas para o Kelsen considerando a flexibilidade do quadro de interpretações. Expõe, primeiramente, a suposta transição do conceito de interpretação normativa, passando de um formalismo-normativismo restritivo para um realismo jurídico a partir das suas últimas obras; em um segundo momento apresenta o decorrente conflito ainda atual constituído por essas reformulações. Finalmente, defende a hipótese de superação da dicotomia formalismo-normativismo versus realismo jurídico através de uma leitura realista normativista.

Katz denies that organisms created in a lab as part of a de-extinction attempt will be authentic members of the extinct species, on the basis that they will lack the original species’ defining biological and evolutionary history. Against Katz, I note that an evolutionary lineage is conferred on an organism through its inheriting genes from forebears already possessed of such a lineage, and that de-extinction amounts to a delayed, human-assisted reproductive process, in which genes are inherited from forebears long dead. (...) My conclusion is that de-extinct organisms can perfectly well have an ancient evolutionary history, contrary to what Katz claims. (shrink)

Blame is multifarious. It can be passionate or dispassionate. It can be expressed or kept private. We blame both the living and the dead. And we blame ourselves as well as others. What’s more, we blame ourselves, not only for our moral failings, but also for our non-moral failings: for our aesthetic bad taste, gustatory self-indulgence, or poor athletic performance. And we blame ourselves both for things over which we exerted agential control (e.g., our voluntary acts) and for things over (...) which we lacked such control (e.g., our desires, beliefs, and intentions). I argue that, despite this manifest diversity in our blaming practices, it’s possible to provide comprehensive account of blame. Indeed, I propose a set of necessary and sufficient conditions that aims to specify blame’s extension in terms of its constitution as opposed to its function. And I argue that this proposal has a number of advantages beyond accounting for blame in all its disparate forms. For one, it can account for the fact that one’s having had control over whether one was to φ is a necessary condition for one’s being fittingly blamed for having φ-ed. For another, it can account for why, unlike fitting shame, fitting blame is always deserved, which in turn explains why there is something morally problematic about ridding oneself of one’s fitting self-blame (e.g., one’s fitting guilt).

With his 1998 book, In Nature’s Interests? Gary Varner proved to be one of our most original and trenchant of environmental ethicists. Here, in the first of a promised two volume set, he makes his mark on another field, animal ethics, leaving an even deeper imprint. Thoroughly grounded in the relevant philosophical and scientific literatures, Varner is as precise in analysis as he is wide-ranging in scope. His writing is clear and rigorous, and he explains philosophical nuances with extraordinary (...) economy of expression. Never one to add an unnecessary clause to a sentence, Varner nonetheless constructs a formidable edifice while always dealing fairly with the authors he criticizes. His explication of the properties and moral status of what he calls near-persons is a crucial addition to the discussion of personhood initiated by Parfit in Reasons and Persons and subsequently applied to animals by McMahan in The Ethics of Killing. The comparison to McMahan is intentional for, to my mind, Varner vies with him as the most important animal ethicist since Singer and Regan. (shrink)

It seems intuitively obvious that metameric matching of color samples entails a loss of information, for spectrophotometrically diverse materials appear the same. This intuition implicitly relies on a conception of the function of color vision and on a related conception of how color samples should be individuated. It assumes that the function of color vision is to distinguish among spectral energy distributions, and that color samples should be individuated by their physical properties. I challenge these assumptions by articulating a different (...) conception of the function of color vision, according to which color vision serves to partition object surfaces into discrimination classes.

This essay is my brief review of Nicholas Phillipson’s biography of Adam Smith. I discuss the highlights of his treatment of Smith’s fascinating life.

Habermas frequentemente adota o termo Estado de direito na sua obra Direito e democracia: entre facticidade e validade.

Would compulsory treatment or vaccination for Covid-19 be justified? In England, there would be significant legal barriers to it.

In this essay, I want to explore one of the most ironic episodes in the history of propaganda, the attempt by various federal agencies to moderate American WWII anti-Japanese propaganda films. My texts will be four films, two produced by the military, and two by Hollywood: December 7th (1943), directed by Gregg Toland and revised by John Ford; Air Force (1943), directed Howard Hawks; Know Your Enemy: Japan (1945), directed by Frank Capra; and Betrayal for the East (1945), directed by (...) William Berke. As all of these films are readily available on YouTube, I will be brief in my description of them. Instead, I will focus on how they served to intensify racial hatred of Japanese in general and Japanese-Americans in particular, and how the federal government tried to control that propaganda—but was limited by its own policies regarding Japanese-Americans.

In this article, I set forth a theory of propaganda explaining what it is, how it relates to marketing, and the nature and types of ideology. I discuss the criteria by which we can judge the rationality or deceitfulness of propaganda. I defend the view that while propaganda can be perfectly rational, it rarely is, and I explain why that is the case. I finish by explaining why the question of the rationality or deceitfulness of propaganda is different from the (...) question of the morality of propaganda. I give two quick examples of how an ethicist might argue that deceptive propaganda might be ethical to use, and perfectly rational propaganda might be immoral to use. I conclude with the notion that the question of the ethics of marketing and propaganda is complex, and should be handled in a separate paper. (shrink)

The theory of knowledge in early twentieth-century Anglo American philosophy was oriented toward phenomenally described cognition. There was a healthy respect for the mind-body problem, which meant that phenomena in both the mental and physical domains were taken seriously. Bertrand Russell's developing position on sense-data and momentary particulars drew upon, and ultimately became like, the neutral monism of Ernst Mach and William James. Due to a more recent behaviorist and physicalist inspired "fear of the mental", this development has been down-played (...) in historical work on early analytic philosophy. Such neglect assumes that the "linguistic turn" is a proper and permanent effect of twentieth-century philosophy, an assumption that distorts early analytic historiography, and begs a substantive philosophical question about thought and cognition.

Studies of visual event individuation often consider people's representations of activities involving agents performing complex tasks. Concomitantly, theories of event individuation emphasize predictions about agents' intentions. Studies that have examined simple, non-agential occurrences leave open the possiblity that principles of visual object individuation play a role in visual event individuation. Unearthing principles that may be sufficient for event individuation which are distinct both from predictions about agents' intentions and from visual object individuation, we draw on and extend studies that reveal (...) object and event representation to be deeply analogous in our cognitive economy. We provide evidence that ‘temporal shaping' is a sufficient low-level perceptual criterion for the visual individuation of events. In our study, temporal shaping is effected by the introduction of pauses into an otherwise continuous process. Future studies should address other visual mechanisms for introducing temporal shaping (e.g., color changes). (shrink)

In 2016, this Journal published an article by Rob Lawlor1 on what we might call the acceptance-refusal asymmetry in competence requirements. This is the view that there can be cases in which a patient is sufficiently competent to accept a treatment, but not sufficiently competent to refuse it. Though the main purpose of Lawlor’s paper was to distinguish this asymmetry from various other asymmetries with which it has sometimes been confused,1 Lawlor also presented a brief case in favour of it. (...) Developing an earlier argument of Ian Wilks’,2 3 Lawlor argued that, when the risks associated with refusing a treatment are graver than those associated with accepting it, a higher level of competence may be required to refuse a treatment than to accept it. This claim could have important implications for the law, since determinations of competence often play a central role in determining the lawfulness of refusing or imposing a treatment. Indeed, the acceptance-refusal asymmetry in competence requirements, or something close to it, has played an important role in court judgments.2 However, Lawlor himself suggests that his conclusion will have practical implications only in a narrow range of cases.3 In this issue, Pickering, Giles Newton-Howes and Simon Walker respond to Lawlor’s piece.4 They deny that competence requirements should depend on the level of risk associated with a decision, and thus that there is any basis for the acceptance-refusal asymmetry in competence requirements. Part of the authors’ argument involves contesting the way in which Lawlor uses cases to support his view. In one case cited by Lawlor—and drawn from Wilks—we are invited to consider a whether ….

With an eye on the future of global ethics, I argue that social-media technologies are not morally neutral tools but are, for all intents and purposes, a kind of agent. They nudge us to do things that are bad for us. Moreover, I argue that we have a duty to quit using social-media platforms, not just on account of possible duties to preserve our own well-being but because users are akin to test subjects on whom developers are testing new nudges, (...) and we ought to deprive them of their test subjects.

A teoria do Direito internacional de Kelsen é monista, ou seja, o autor reúne a legislação nacional e internacional em um único sistema normativo. Com isso, descarta o dualismo e promove uma tese fundada no princípio lógico da não-contradição, traduzido juridicamente para o princípio da imputação. Por essa afirmação, o Direito internacional, considerando o primado estadual, existe a partir do reconhecimento interno da validade da legislação externa; mais, a recepção dos acordos internacionais na legislação nacional acopla internamente o Direito internacional, (...) com seus tratados bi/multilaterais, pactos, instituições, costumes e tribunais. A teoria de Kelsen torna-se complexa, porém, quando, indagando o inverso dessa premissa, o Direito internacional posto e eficaz, já inserido internamente, não reconhece a validade normativa de eventual interpretação ou norma interna e atua como agente determinante da ordem jurídica nacional. Com isso, o Direito externo torna-se decisivo desse mesmo sistema jurídico interno, não necessariamente por uma ação coercitiva, mas por intermédio do seu reconhecimento da validade da legislação interna. Vimos esse fenômeno materializar-se no caso dos dois presidentes simultâneos da Venezuela: tanto o presidente Nicolás Maduro, quando o presidente Juan Guaidó, foram formalmente designados, por países e instituições distintas, como governantes válidos. Sendo assim, o objetivo do livro consiste em compreender esse fenômeno de reconhecimento externo dos sistemas normativos nacionais através da segunda edição da Teoria de pura do Direito como marco teórico. Igualmente, utiliza-se do estudo de caso sobre a determinação do presidente válido da Venezuela como elemento empírico e de falseabilidade. Com isso, defende a hipótese da necessidade do reconhecimento normativo-objetivo do Estado a partir da formação do Direito internacional, independentemente de seu primitivismo. Os quatro primeiros capítulos, na primeira seção, estabelecem uma interpretação sobre a obra de Kelsen, focada em seu aspecto internacionalista. Nos quatro últimos, na seção II, submeto as conclusões teóricas ao caso concreto, falseando-as ou não conforme seu teste empírico. (shrink)

In this article, I explore how efficacious film can be in countering propaganda in film. To set up the discussion, I first sketch out a simple theory of propaganda, under which propaganda can be ranked from completely rational to very irrational, on six different dimensions. These are the degrees to which the propaganda is: evidence-based; truthful; broadly logical; transparent; properly targeted; and transparent. I then review in detail the main propaganda film, Gasland. This film was a highly successful documentary that (...) attacked the production of natural gas by hydrofracturing, called in America “fracking.” Gasland succeeded in organizing domestic opposition to fracking, actually blocking it in the Delaware River Basin system. The film was also influential abroad, leading to fracking bans in France, Bulgaria, and elsewhere in Europe. Next, I review in detail two counter-propaganda films—that is, in this case, two pro-fracking documentaries: Truthland and FrackNation. Truthland is a short documentary that aims at rebutting many of Gasland’s major claims. It was funded by the fracking industry and had limited distribution but it succeeded in refuting much of the longer and better-funded anti-fracking film. A much more successful film in terms of both general distribution and efficacy of rebuttal was the much longer pro-fracking documentary FrackNation. It critiques all of Gasland’s major points, in vivid detail. Since it was crowdfunded, it couldn’t be dismissed on the grounds that it was biased because of being industry-backed. I conclude by explaining why the pro-fracking documentaries did not result in a major change in public opinion. (shrink)

O objetivo do artigofoi especular sobre a epistemologia proposta por David Hume (1711-1776), especificamente a perspectiva empirista e cética. Procurou-se, assim, expor os principais conceitos da sua filosofia, especialmente acrítica à concepção de causalidade, o problema da probabilidade e os conceitos de percepções, imagens e ideias. Finalmente buscou-se expor uma interpretação que entende haver um ceticismo mitigado no autor e a superação de uma teoria do conhecimento exclusivamente psicológica.

The term ‘propaganda’ is normally taken in the pejorative sense of deceitful messaging. Propaganda is considered dubious if it is produced by a government agency, especially by a ministry of war or propaganda. In this article, I apply the theory of propaganda I sketched in a prior piece in these pages, under which propaganda is simply messaging intended to persuade others to do something or to support something. Under this theory, propaganda is reasonable if but only if it is evidence-based, (...) truthful, broadly logical, not coercive, targeted at mentally competent adults, and transparent—meaning that the audience should be aware that the message is intended to persuade them to do or support something. I then examine three WWII-era government propaganda films, one—A Defeated People (1946)—produced by the British military, and two—The Negro Soldier (1944) and Teamwork (1947)—produced by the American military. I explain first why I chose these particular films. I then analyze these films in some detail and show that while they were not perfectly rational, they all effectively conveyed the persuasive message that the respective militaries wanted to convey. And they did this by meeting all of the criteria for propaganda to be rational. (shrink)

A separação entre o ser, isto é, o ato, e o dever-ser, ou seja, o sentido de comando, permissão etc.. do ato é parte fundamental para o entendimento da epistemologia proposta por Hans Kelsen. Dessa discriminação entre o ser e o dever-ser há o principal argumento do autor para a separação do direito das ciências causais e, principalmente, a superação da falácia naturalista no âmbito teórico e moral. Nesse sentido, também o artigo se propôs a analisar a refutação de Kelsen (...) a doutrinas morais e jurídicas negadoras de tal distinção e, consequentemente o reflexo de tal posicionamento na perspectiva da responsabilidade.

O artigo investigou o método para uma filosofia intercultural a partir da Ibero-América, de Raul Fornet-Betancourt. Partiu-se especificamente do texto do autor para posteriormente fornecer considerações críticas aos seus posicionamentos. Nesse sentido, analisou-se a originalidade do tema, a filosofia da libertação como modelo de diálogo intercultural, seus pressupostos hermenêuticos e epistemológicos e, por fim, o pensamento ibero-americano como base para uma filosofia intercultural. No final do trabalho apresentou-se seis críticas ao texto estudado – o problema da arrogância e dissimulação filosófica, (...) a adoção tácita de um platonismo e a não originalidade filosófica, o problema da falácia naturalista e do falsificacionismo e, finalmente, a não razoabilidade política das propostas.

Com este artigo procura-se introduzir a questão da origem social das normas morais e jurídicas a partir da obra de Hans Kelsen e solucionar, de forma breve, o problema da conciliação do método lógico-transcendental da Teoria pura com a filosofia positivista e empirista do autor.
