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 (...) with an introduction to Type I error rates that distinguishes them from 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)

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.

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)

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)

In a recent paper I proposed a novel relativity theory termed Information Relativity (IR). Unlike Einstein's relativity which dictates as force majeure that relativity is a true state of nature, Information Relativity assumes that relativity results from difference in information about nature between observers who are in motion relative to each other. The theory is based on two axioms: 1. the laws of physics are the same in all inertial frames of reference (Special relativity's first axiom); 2. All translations of (...) information from one frame of reference to another are carried by light or by another carrier with equal velocity (information-carrier axiom). For the case of constant relative velocities, I showed in the aforementioned paper that IR accounts successfully for the results of a class of relativistic time results, including the Michelson-Morley's "null" result, the Sagnac effect, and the neutrino velocities reported by OPERA and other collaborations. Here I apply the theory, with no alteration, to cosmology. I show that the theory is successful in accounting for several cosmological findings, including the pattern of recession velocity predicted by inflationary theories, the GZK energy suppression phenomenon at redshift z ̴ 1.6, and the amounts of matter and dark energy reported in recent ΛCDM cosmologies.

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)

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 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.

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.

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)

The National Center for Biomedical Ontology is a consortium that comprises leading informaticians, biologists, clinicians, and ontologists, funded by the National Institutes of Health (NIH) Roadmap, to develop innovative technology and methods that allow scientists to record, manage, and disseminate biomedical information and knowledge in machine-processable form. The goals of the Center are (1) to help unify the divergent and isolated efforts in ontology development by promoting high quality open-source, standards-based tools to create, manage, and use ontologies, (2) to create (...) new software tools so that scientists can use ontologies to annotate and analyze biomedical data, (3) to provide a national resource for the ongoing evaluation, integration, and evolution of biomedical ontologies and associated tools and theories in the context of driving biomedical projects (DBPs), and (4) to disseminate the tools and resources of the Center and to identify, evaluate, and communicate best practices of ontology development to the biomedical community. Through the research activities within the Center, collaborations with the DBPs, and interactions with the biomedical community, our goal is to help scientists to work more effectively in the e-science paradigm, enhancing experiment design, experiment execution, data analysis, information synthesis, hypothesis generation and testing, and understand human disease.

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)

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)

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)

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 trabalho busca esclarecer dois pontos centrais da Filosofia política de Maquiavel – as figuras da Virtù e da Fortuna. A virtú deve ser vista como uma forma do livre-arbítrio do governante, sendo a principal variável na condução do principado.Destaca-se, também, a utilização da variável nacontestação aos valorestradicionais. Já a Fortuna constitui-se na indeterminabilidade de parte dos resultadosdo governo: ela deve ser dominada, conquistada para o benefício do príncipe.

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.

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)

O objetivo do trabalho é auxiliar o jurista desocupado responsável pelo ensino da cadeira de filosofia do direito. A situação mais frequente nas faculdades de direito são as aulas de filosofia e de outras cadeiras do eixo fundamental serem tapeadas por qualquer bacharel sem nada melhor para fazer. Ocorre que tais ociosos juristas muitas vezes se veem receosos quando instituídos nos seus cargos, isso porque não possuem qualquer conhecimento na matéria em que lecionam, ao mesmo tempo em que são lançados (...) em sala de aula expostos às dúvidas e críticas dos alunos. Nesse sentido apresento a esses professores, juristas desocupados, uma técnica pedagógica resumida e de fácil compreensão para ministrarem sem maiores sobressaltos a cadeira de filosofia do direito. Seguindo os passos propostos, o jurista desocupado não terá riscos de ser questionado pelos alunos ou pela instituição, mantendo seu complemento de renda garantido. (shrink)

Pretendeu-se dissertar acerca do conceito kantiano do Direito a partir da gênese da sua fundamentação moral, ressaltando a aprioricidade da mesma e seu reflexo na doutrina jurídica. Contrariamente ao moral sense da Filosofia empirista inglesa, a moralidade kantiana baseia-se completamente a priori, abdicando de uma antropologia em sua exposição e formulando-se como pura metafísica, a partir de conhecimentos abstratos. Coaduna à concepção de moralidade kantiana o seu conceito de Direito, que também não possui, portanto, qualquer fundamento na experiência. Desta forma, (...) pretende-se fornecer uma interpretação sistemática em relação aos problemas da doutrina do direito, especificamente sobre a sua exterioridade, a função da coerção e a formação do Estado.

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)

A presente dissertação tem como tema central a proposta da abordagem hermenêutica da decisão judicial em Hans Kelsen considerando seu relativismo filosófico. No primeiro momento expõe a concepção de decisão judicial no autor e as suas reformulações conceituais no decorrer das suas obras – as passagens do formalismo normativista das primeiras obras até o ceticismo de regras na Teoria geral das normas. Também propõe a dissolução entre as leituras formalistas e realistas através da possibilidade de uma leitura realista moderada. Após (...) expõe a filosofia relativista do autor e seu resultado na exclusão dos elementos da moralidade do conceito de direito. Finalmente deduz regras de interpretação a partir de uma visão abrangente das obras do autor. O objetivo da dissertação, nesse sentido, é analisar a dinâmica da criação normativa pelo judiciário, a discricionariedade daí resultante e a possibilidade de interpretar os vários sentidos das normas sem recorrer a qualquer moralismo para tal.

Habermas frequentemente adota o termo Estado de direito na sua obra Direito e democracia: entre facticidade e validade. O objetivo deste artigo, então, consiste na investigação da possibilidade desse conceito, no seu fundamento e na apresentação dos problemas dele decorrentes, contrapondo-o especificamente a sua antítese, isto é, ao monismo entre Estado e direito de Kelsen. Ocorre que a filosofia habermasiana, conforme entendimento do artigo, implica a adoção de uma teoria dualista entre os conceitos de Estado e de direito. Observa-se, assim, (...) o compromisso do filósofo alemão com a reformulação de uma doutrina jurídica específica e sua radical incompatibilidade com o positivismo kelseniano. (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.

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.

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)

A tese defende o antiplatonismo presente na obra do jusfilósofo Hans Kelsen como núcleo argumentativo da sua teoria do direito. Sustenta que a melhor definição da sua filosofia não é como neokantiana, mas como antiplatônica. Isso porque há significativas inconsistências na sua interpretação de Kant, o que a impossibilita de ser classificada como tal. Além, encontra-se na sua leitura sobre Platão referências mais sólidas e conceitos mais claros. Nesse sentido, advoga a hipótese de que a obra de Kelsen tem como (...) constante e como chave de entendimento a sua objeção e contestação às teses de Platão, sobretudo a questão da separação entre alma e corpo, isto é, forma e matéria. O primeiro e segundo capítulos defendem a hipótese da inconsistência das teses de Kelsen sobre Kant. Entende que a sua pressuposição de contradição entre a razão pura e a razão prática, assim como a ideia de uma contradição entre ser e dever-ser, não se sustenta considerando as próprias obras de Kant e a literatura especializada sobre o autor. No segundo capítulo apresenta a sua leitura sobre Platão, concentrada na obra A Ilusão da justiça (Dei Illusion der Gerechtigkeit). O quarto capítulo expõe, sopesando seu antiplatonismo, as duas principais referências teóricas para Kelsen a par de Kant, isto é, as teorias de David Hume e Sigmund Freud. O quinto capítulo demonstra como o antiplatonismo de Kelsen articula com os principais conceitos de suas teses, isto é, mostra que mesmo refutando a classificação do autor como neokantiano, conceitos como norma fundamental, liberdade, o monismo entre direito e Estado, monismo entre direito internacional e nacional e o problema da decisão judicial possuem justificativa e base filosófica coerente. Finalmente, conclui com a possiblidade da ideia de uma teoria kelseniana do direito desvinculada do neokantismo e fundada sobre os pressupostos céticos humeanos e freudianos, tanto moral, quanto teórico, ou seja, reconhece a unidade das obras do autor, desde que condicionada a sua interpretação como antiplatônica.

On a literal reading of `Computing Machinery and Intelligence'', Alan Turing presented not one, but two, practical tests to replace the question `Can machines think?'' He presented them as equivalent. I show here that the first test described in that much-discussed paper is in fact not equivalent to the second one, which has since become known as `the Turing Test''. The two tests can yield different results; it is the first, neglected test that provides the more appropriate indication of intelligence. (...) This is because the features of intelligence upon which it relies are resourcefulness and a critical attitude to one''s habitual responses; thus the test''s applicablity is not restricted to any particular species, nor does it presume any particular capacities. This is more appropriate because the question under consideration is what would count as machine intelligence. The first test realizes a possibility that philosophers have overlooked: a test that uses a human''s linguistic performance in setting an empirical test of intelligence, but does not make behavioral similarity to that performance the criterion of intelligence. Consequently, the first test is immune to many of the philosophical criticisms on the basis of which the (so-called) `Turing Test'' has been dismissed. (shrink)

Let us suppose that we accept that humans can be correctly characterized as agents. Let us further presume that this capacity contrasts with most non-human animals. Thus, since agency is what uniquely constitutes what it is to be human, it must be of supreme importance. If these claims have any merit, it would seem to follow that, if agency can be nurtured through education, then it is an overarching moral imperative that educational initiatives be undertaken to do that. In this (...) paper, it will be argued that agency can indeed be enhanced, and that the worldwide educational initiative called Philosophy for Children, and others like it, are in a unique position to do just that, and, therefore, that P4C deserves our praise and support; while denigrations of such efforts for not being “real philosophy” ought to be thoroughly renounced.

In this analysis of one of the most difficult and neglected topics in Hegelian studies, Songsuk Susan Hahn tackles the status of contradiction in Hegel's ...

A tese defende o antiplatonismo presente na obra do jusfilósofo Hans Kelsen como núcleo argumentativo da sua teoria do direito. Sustenta que a melhor definição da sua filosofia não é como neokantiana, mas como antiplatônica. Isso porque há significativas inconsistências na sua interpretação de Kant, o que a impossibilita de ser classificada como tal. Além, encontra-se na sua leitura sobre Platão referências mais sólidas e conceitos mais claros. Nesse sentido, advoga a hipótese de que a obra de Kelsen tem como (...) constante e como chave de entendimento a sua objeção e contestação às teses de Platão, sobretudo a questão da separação entre alma e corpo, isto é, forma e matéria. O primeiro e segundo capítulos defendem a hipótese da inconsistência das teses de Kelsen sobre Kant. Entende que a sua pressuposição de contradição entre a razão pura e a razão prática, assim como a ideia de uma contradição entre ser e dever-ser, não se sustenta considerando as próprias obras de Kant e a literatura especializada sobre o autor. No segundo capítulo apresenta a sua leitura sobre Platão, concentrada na obra A Ilusão da justiça (Dei Illusion der Gerechtigkeit). O quarto capítulo expõe, sopesando seu antiplatonismo, as duas principais referências teóricas para Kelsen a par de Kant, isto é, as teorias de David Hume e Sigmund Freud. O quinto capítulo demonstra como o antiplatonismo de Kelsen articula com os principais conceitos de suas teses, isto é, mostra que mesmo refutando a classificação do autor como neokantiano, conceitos como norma fundamental, liberdade, o monismo entre direito e Estado, monismo entre direito internacional e nacional e o problema da decisão judicial possuem justificativa e base filosófica coerente. Finalmente, conclui com a possiblidade da ideia de uma teoria kelseniana do direito desvinculada do neokantismo e fundada sobre os pressupostos céticos humeanos e freudianos, tanto moral, quanto teórico, ou seja, reconhece a unidade das obras do autor, desde que condicionada a sua interpretação como antiplatônica.

Summary Analogue models are actual physical setups used to model something else. They are especially useful when what we wish to investigate is difficult to observe or experiment upon due to size or distance in space or time: for example, if the thing we wish to investigate is too large, too far away, takes place on a time scale that is too long, does not yet exist or has ceased to exist. The range and variety of analogue models is too (...) extensive to attempt a survey. In this article, I describe and discuss several different analogue model experiments, the results of those model experiments, and the basis for constructing them and interpreting their results. Examples of analogue models for surface waves in lakes, for earthquakes and volcanoes in geophysics, and for black holes in general relativity, are described, with a focus on examining the bases for claims that these analogues are appropriate analogues of what they are used to investigate. A table showing three different kinds of bases for reasoning using analogue models is provided. Finally, it is shown how the examples in this article counter three common misconceptions about the use of analogue models in physics. (shrink)

A metainference is usually understood as a pair consisting of a collection of inferences, called premises, and a single inference, called conclusion. In the last few years, much attention has been paid to the study of metainferences—and, in particular, to the question of what are the valid metainferences of a given logic. So far, however, this study has been done in quite a poor language. Our usual sequent calculi have no way to represent, e.g. negations, disjunctions or conjunctions of inferences. (...) In this paper we tackle this expressive issue. We assume some background sentential language as given and define what we call an inferential language, that is, a language whose atomic formulas are inferences. We provide a model-theoretic characterization of validity for this language—relative to some given characterization of validity for the background sentential language—and provide a proof-theoretic analysis of validity. We argue that our novel language has fruitful philosophical applications. Lastly, we generalize some of our definitions and results to arbitrary metainferential levels. (shrink)

There are kinds of dialogue that support social justice and others that do the reverse. The kinds of dialogue that support social justice require that anger be bracketed and that hiding in safe spaces be eschewed. All illegitimate ad hominem/ad feminem attacks are ruled out from the get-go. No dialogical contribution can be down-graded on account of the communicator’s gender, race, or religion. As well, this communicative approach unapologetically privileges reason in full view of theories and strategies that might seek (...) to undermine reasoning as just another illegitimate form of power. On the more positive side, it is argued in this paper that social justice dialogue will be enhanced by a kind of “communicative upgrading,” which amplifies “person perception,” foregrounds the impersonal forces within our common social spaces rather than the “baddies” within, and orients the dialogical trajectory toward the future rather than the past. Finally, it is argued in this paper that educators have a pressing responsibility to guide their students through social justice dialogue so that their speech contributes to the amelioration of injustice, rather than rendering the terrain more treacherous.

As the English word “scientism” is currently used, it is a trivial verbal truth that scientism—an inappropriately deferential attitude to science—should be avoided. But it is a substantial question when, and why, deference to the sciences is inappropriate or exaggerated. This paper tries to answer that question by articulating “six signs of scientism”: the honorific use of “science” and its cognates; using scientific trappings purely decoratively; preoccupation with demarcation; preoccupation with “scientific method”; looking to the sciences for answers beyond their (...) scope; denying the legitimacy or worth of non-scientific (e.g., legal or literary) inquiry, or of writing poetry or making art.

In this short paper I will introduce an idea which, I will argue, presents a fundamental additional challenge to the machine consciousness community. The idea takes the questions surrounding phenomenology, qualia and phenomenality one step further into the realm of intersubjectivity but with a twist, and the twist is this: that an agent’s intersubjective experience is deeply felt and necessarily co-affective; it is enkinaesthetic, and only through enkinaesthetic awareness can we establish the affective enfolding which enables first the perturbation, and (...) then the balance and counter-balance, the attunement and co-ordination of whole-body interaction through reciprocal adaptation.

If successful scientific inquiry is to be possible, there must be a world that is independent of how we believe it to be, and in which there are kinds and laws; and we must have the sensory apparatus to perceive particular things and events, and the capacity to represent them, to form generalized explanatory conjectures, and check how these conjectures stand up to further experience. Whether these preconditions are met is not a question the sciences can answer; it is specifically (...) philosophical. This is why the myriad forms of scientistic philosophy in vogue today (neurophilosophy, experimental philosophy, naturalized metaphysics, evangelical-atheist reductionism, etc), are all hollow at the core. Does this mean we must return to the old, a priori analytic model? No! What is needed instead is scientific philosophy in the sense Peirce articulated more than a century ago: philosophy motivated by a genuine desire to discover the truth, and relying not solely on reason but also on experience—only not the special, recherché experience required by the sciences, but close attention to aspects of everyday experience so familiar we hardly notice them.

Given that one of the major goals of the practice of Philosophy for Children (P4C) is the development of critical thinking skills (Sharp 1987/2018, pp. 4 6), an urgent question that emerged for one of the authors, who is of Chinese Heritage and a novice practitioner at a P4C summer camp was whether this emphasis on critical thinking might make this practice incompatible with the fabric of Chinese culture. Filial piety (孝), which requires respect for one’s parents, elders, and ancestors (...) is considered an important virtue in Asian culture, as is the preservation of harmony. But if one of the goals of P4C is to teach youngsters to courageously pursue reasoned dialogue, does this not set-up young Asians for serious conflict when they come face-to-face with positions that are articulated by elders, but which are ones to which they are diametrically opposed; a racist grandmother, for instance, or an uncle who insists that those at the Tiananmen Square uprising were nothing but hooligan’s. It is this question that we will explore in this presentation. In the process, we will come to the conclusion that, when positions seem irreconcilable, rather than continuing to pursue rigorous critical interchange that may do little other than escalate insult, the facilitator, rather, ought to move toward creating a deeper understanding of each position juxtaposed against its opposing view (a process that we refer to as ‘collaborative caring’), so as to produce side-by-side understanding, knowing that communal bonds have been maintained and, hence, that the opportunity for genuine reasoned collaborative inquiry on other issues and at future times remains open.
