Philosophical discussions on causal inference in medicine are stuck in dyadic camps, each defending one kind of evidence or method rather than another as best support for causal hypotheses. Whereas Evidence Based Medicine advocates the use of Randomised Controlled Trials and systematic reviews of RCTs as gold standard, philosophers of science emphasise the importance of mechanisms and their distinctive informational contribution to causal inference and assessment. Some have suggested the adoption of a pluralistic approach to causal inference, and an inductive (...) rather than hypothetico-deductive inferential paradigm. However, these proposals deliver no clear guidelines about how such plurality of evidence sources should jointly justify hypotheses of causal associations. We here develop such guidelines by first giving a philosophical analysis of the underpinnings of Hill’s viewpoints on causality. We then put forward an evidence-amalgamation framework adopting a Bayesian net approach to model causal inference in pharmacology for the assessment of harms. Our framework accommodates a number of intuitions already expressed in the literature concerning the EBM vs. pluralist debate on causal inference, evidence hierarchies, causal holism, relevance, and reliability.

“The Routledge [series] is designed to introduce students to classic works of philosophy. Brian Leiter’s Nietzsche on Morality does that, and much more. The book offers a complete commentary of On the Genealogy of Morality, but it also articulates a comprehensive and original interpretation of Nietzsche’s critique of morality. The product is an exceptionally clear and cohesive account of philosophical views known neither for their clarity nor their cohesiveness…. “The distinction, and the chief merit, of Leiter’s account is its emphasis (...) on the naturalism of Nietzsche’s approach to morality. Leiter may not quite be the first to portray Nietzsche as a naturalist, but his characterization of Nietzschean naturalism in connection with morality is the most systematic and compelling to date…. “In general, the book offers one of the most comprehensive and compelling interpretations of Nietzsche’s critique of morality…. With its distinctive emphasis on naturalistic themes, it forms a very significant contribution to the study of Nietzsche and is poised to become a work of reference in the field. Indeed, even the criticisms I have raised about this interpretation owe much to the exceptional clarity and cogency with which it is articulated.” --Bernard Reginster (Brown University), writing in Notre Dame Philosophical Review, January 2, 2003 (http://ndpr.icaap.org/content/archives/2003/1/reginster-leiter.html).

In teaching jurisprudence, I typically distinguish between two different families of theories of adjudication—theories of how judges do or should decide cases. “Formalist” theories claim that the law is “rationally” determinate, that is, the class of legitimate legal reasons available for a judge to offer in support of his or her decision justifies one and only one outcome either in all cases or in some significant and contested range of cases ; and adjudication is thus “autonomous” from other kinds of (...) reasoning, that is, the judge can reach the required decision without recourse to nonlegal normative considerations of morality or political philosophy. I also note that “formalism” is sometimes associated with the idea that judicial decision-making involves nothing more than mechanical deduction on the model of the syllogism—Beccaria, for example, expresses such a view. I call the latter “Vulgar Formalism” to emphasize that it is not a view to which anyone today cares to subscribe. (shrink)

Brian Leiter draws on empirical psychology to defend a set of radical ideas from Nietzsche: there is no objectively true morality, there is no free will, no one is ever morally responsible, and our conscious thoughts play almost no significant role in our actions. Nietzsche emerges as not just a great philosopher but a prescient psychologist.

According to the objective Bayesian approach to inductive logic, premisses inductively entail a conclusion just when every probability function with maximal entropy, from all those that satisfy the premisses, satisfies the conclusion. When premisses and conclusion are constraints on probabilities of sentences of a first-order predicate language, however, it is by no means obvious how to determine these maximal entropy functions. This paper makes progress on the problem in the following ways. Firstly, we introduce the concept of a limit in (...) entropy and show that, if the set of probability functions satisfying the premisses contains a limit in entropy, then this limit point is unique and is the maximal entropy probability function. Next, we turn to the special case in which the premisses are categorical sentences of the logical language. We show that if the uniform probability function gives the premisses positive probability, then the maximal entropy function can be found by simply conditionalising this uniform prior on the premisses. We generalise our results to demonstrate agreement between the maximal entropy approach and Jeffrey conditionalisation in the case in which there is a single premiss that specifies the probability of a sentence of the language. We show that, after learning such a premiss, certain inferences are preserved, namely inferences to inductive tautologies. Finally, we consider potential pathologies of the approach: we explore the extent to which the maximal entropy approach is invariant under permutations of the constants of the language, and we discuss some cases in which there is no maximal entropy probability function.

Both an introduction to Nietzsche’s moral philosophy, and a sustained commentary on his most famous work, On the Genealogy of Morality, this book has become the most widely used and debated secondary source on these topics over the past dozen years. Many of Nietzsche’s most famous ideas - the "slave revolt" in morals, the attack on free will, perspectivism, "will to power" and the "ascetic ideal" - are clearly analyzed and explained. The first edition established the centrality of naturalism to (...) Nietzsche’s philosophy, generating a substantial scholarly literature to which Leiter responds in an important new Postscript. In addition, Leiter has revised and refreshed the book throughout, taking into account new scholarly literature, and revising or clarifying his treatment of such topics as the objectivity of value, epiphenomenalism and consciousness, and the possibility of "autonomous" agency.

Nietzsche famously proclaimed the “death of God,” but in so doing it was not God’s death that was really notable—Nietzsche assumes that most reflective, modern readers realize that “the belief in the Christian god has become unbelievable” —but the implications of that belief becoming unbelievable, namely, “how much must collapse now that this faith has been undermined,” in particular, “the whole of our European morality”. What is the connection between the death of God and the death of morality? I argue (...) that Nietzsche thinks the death of God will undermine the “moral egalitarianism” that is central to modern morality, in both its deontological and utilitarian forms. I offer an account of how Nietzsche sees the connection, arguing that no one has yet offered a nontheistic defense of moral egalitarianism. I conclude with some skeptical considerations about whether Nietzsche was right that atheism would, in fact, undermine morality. (shrink)

I am grateful to Alan Madry and Joel Richeimer for their intelligent and stimulating critique of my article “Heidegger and the Theory of Adjudication.” It is the most interesting commentary I have seen on the paper, and I have learned much from it. It may facilitate discussion, and advance debate, to state with some clarity where exactly we agree and disagree. I leave to the footnotes discussion of certain minor points where Madry and Richeimer are guilty of some critical overreaching.

This article sketches an idealized strategy for the identification of neural correlates of consciousness. The proposed strategy is based on a state space approach originating from the analysis of dynamical systems. The article then focuses on one constituent of consciousness, phenomenal awareness. Several rudimentary requirements for the identification of neural correlates of phenomenal awareness are suggested. These requirements are related to empirical data on selective attention, on completely intrinsic selection and on globally unconscious states. As an example, neuroscientific findings on (...) synchronized γ activity are categorized according to these requirements. (shrink)

This chapter contains sections titled: Introduction Denial of Free Will and Moral Responsibility Against the Causality of the Will The Genesis of Action A ‘Persuasive (Re)Definition’ of Free Will References.

Nietzsche is one of the most important and controversial thinkers in the history of philosophy. His writings on moral philosophy are amongst the most widely read works, both by philosophers and non-philosophers. Many of the ideas raised are both startling and disturbing, and have been the source of great contention. On the Genealogy of Morality is Nietzsche's most sustained and important contribution to moral philosophy, featuring many of the ideas for which he is best known, including the slave revolt in (...) morals; will to power; genealogy; and perspectivism. The Routledge Philosophy GuideBook to Nietzsche on Morality introduces the reader to these and other important Nietzschean themes patiently and clearly. It is the first book to examine the work in such a way, and will be a vital point of reference for any Nietzsche scholar, and essential reading for students coming to Nietzsche for the first time.

The “terrible” existential truths about the human situation raise Schopenhauer's question: why continue living at all? Nietzsche's answer is that only viewed in terms of aesthetic values can life itself be “justified”. But how could the fact that life exemplifies aesthetic value restore our attachment to life in the face of these terrible existential truths? I suggest that there are two keys to understanding Nietzsche's answer: first, his assimilation of aesthetic pleasure to a kind of sublimated sexual pleasure; and second, (...) his psychological thesis that powerful affects neutralize pain, and thus can “seduce” the sufferer back to life. Life can supply the requisite kind of aesthetic pleasure only if it features what I call the “spectacle of genius,” the spectacle represented by the likes of Beethoven, Goethe, and Napoleon. Since such geniuses are not possible in a culture dominated by “morality”, the critique of morality is essential to the restoration of an affective attachment to life. (shrink)

Marx did not have a normative theory, that is, a theory that purported to justify, discursively and systematically, his normative opinions, to show them to be rationally obligatory or objectively valid. In this regard, Marx was obviously not alone: almost everyone, including those who lead what are widely regarded as exemplary ‘moral’ lives, decide and act on the basis of normative intuitions and inclinations that fall far short of a theory. Yet self-proclaimed Marxists like G. A. Cohen and Jurgen Habermas (...) have reintroduced a kind of normative theory into the Marxian tradition that Marx himself would have ridiculed. This essay defends Marx’s position and tries to explain the collapse of Western Marxism into bourgeois practical philosophy, i.e., philosophizing about what ought to be done that is unthreatening to capitalist relations of production.

We study questionnaire responses to situations in which sacrificing one life may save many other lives. We demonstrate gender differences in moral judgments: males are more supportive of the sacrifice than females. We investigate a source of the endorsement of the sacrifice: antisocial preferences. First, we measure individual proneness to spiteful behavior, using an experimental game with monetary stakes. We demonstrate that spitefulness can be sizable—a fifth of our participants behave spitefully—but it is not associated with gender. Second, we find (...) that gender is consistently associated with responses even when we account for individual differences in the propensity to spitefulness. (shrink)

As digital media becomes more central to the lives of adolescents, it also becomes increasingly relevant for their sexual communication. Sexting as an important image-based digital medium provides opportunities for self-determined digital communication, but also carries specific risks for boundary violations. Accordingly, sexting is understood either as an everyday, or as risky and deviant behavior among adolescents. In the affectedness of boundary violations gender plays an important role. However, it is still unclear to what extent digital sexual communication restores stereotypical (...) gender roles and restrictive sexuality norms or, alternatively, enables new spaces of possibility. In this sense, current research points to a desideratum regarding adolescents’ orientations toward sexting as a practice between spaces of possibility and boundary violations. This paper discusses the possibilities, but also the risks, of intimate digital communication among adolescents. The main question is, how adolescents themselves perceive sexting practices and how they position themselves between both spaces for possibility and for the exchange of unwanted sexual content. For this purpose, orientations toward normalities and gender of students are reconstructed. To answer these questions, twelve single-sex, group discussions were carried out with students aged 16 and 17 at five different secondary schools in northern Germany. A total of 20 boys and 22 girls took part. The group discussions were structured by a narrative generating guideline. The analysis draws its methodology from the Documentary Method, regarding implicit and explicit forms of knowledge and discourse. It results in a typology of three types with different orientations. The study shows, that most of the students consider sexting to be a risky practice; only one type shows normality in the use of sexting. At the same time, some of the young people are interested in experimenting with image-based intimate digital communication. Further, gender differences in use and affectedness are also documented. In this way, orientations toward gender stereotypes “favor” both the attribution of responsibility to girls, and overlook the responsibility of students who perpetrated the boundary violation. The orientations of adolescents should be taken more into account in research as well as in educational programs for the prevention of sexual violence. (shrink)

Palabras pronunciadas por Jürgen Habermas en el Memorial a Richard Rorty con motivo de su fallecimiento, ceremonia que tuvo lugar en la Universidad de Stanford el día 2 de noviembre de 2007.

This is an invited commentary on Richard Rorty's Dewey Lecture, given last year at the University of Chicago Law School. “Pragmatism,” says Rorty, “puts natural science on all fours with politics and art. It is one more source of suggestions about what to do with our lives.” I argue that the truth in pragmatism - that the epistemic norms that help us cope are the ones on which we rely - is obscured by Rorty's promiscuous version of the doctrine, which (...) confuses the criteria for relying on particular epistemic norms (namely, that they work for human purposes) with the content of the norms themselves (most of which make no reference to human purposes, but rather criteria like causal or explanatory power). We need presuppose no Archmiedean standpoint to conclude, as Richard Posner does, that moral inquiry is feeble in a way physics is not; we need only take seriously our best current understanding of the world, how it works, and the epistemic norms that have proven most effective in making sense of it.

Where does philosophy, the oldest academic subject, stand at the beginning of the new millennium? This remarkable volume brings together leading figures from most major branches of the discipline to offer answers. What remains of the "linguistic turn" in twentieth-century philosophy? How should moral philosophy respond to and incorporate developments in empirical psychology? Where might Continental and Anglophone feminist theory profitably interact? How has our understanding of ancient philosophy been affected by the emergence of analytic philosophy? Where does the mind-body (...) problem stand today? What role must value judgments play in science? Do Marx, Nietzsche, or Freud matter in the 21st century? These and many other questions at the cutting edge of the discipline are addressed by distinguished philosophers from Australia, Britain, Canada, and the United States. They aim not only to stimulate philosophical debate, but to introduce those in cognate disciplines--biology, classics, economics, history, law, linguistics, literary studies, mathematics, philosophy, physics, political science, psychology, among others--to what is happening in contemporary philosophy. In a substantial introduction, the editor gives an overview of the state of philosophy today and helps orient non-philosophers.

Abstract‘[T]he “mainstream” of global governance has changed course’ and in so doing, might well have ‘outrun the standard tools of critical, progressive, and reform-minded international lawyers’, Fleur Johns wrote in 2019. It is especially the critical tools of ‘appeals to history, context, language [and] the grassroots’ in response to universalist planning that Johns sees absorbed in the turn to prototyping as a new ‘style’ of governance. In this article, we take on this observation and explore how the ‘lean start-up mentality’ (...) that Johns described has taken hold of tech-based climate governance. We base our reflections on the ‘Tech for Our Planet’ challenge that took place over 2021 and was showcased at the UNFCCC COP26 in Glasgow. While a turn ‘from planning to prototypes’ is observable, we question how exactly this ‘change of course’ affects the high modernist style of global governance and its critique by international lawyers. The ‘digital solutions for climate challenges’ that were showcased in Glasgow are indeed based on localized experiments with data science, thereby seemingly overcoming high modernist impulses towards universalist ideals. Yet, these experimental prototypes are developed with the ambition of being replicable and scaled up, to become a stack of tools deployable in any given scenario. This form of scaling up neither breaks with modernist aspirations based on technologically-mediated replicability—of moving the same logic inscribed in code to different sites and contexts—nor with a modernist understanding of knowledge as universal in its application. In our analysis, the determining feature is then not so much a matter of planning or prototyping in ideal type forms, but of replicability of knowledge production and scalability of technological know-how that underpin both planning and prototyping. Prototyping in the start-up space does not depart from, but rather reinscribes, a modernist representation of the human subject that forces its epistemological lens onto a world of nonhuman objects amenable to governance. Critical international lawyers’ toolkits must therefore be reconfigured with a focus on a governance style of disembodied knowledge production that runs through both planning and prototyping.

ABSTRACTI offer an interpretation of Nietzsche's striking idea of ‘the innocence of becoming’, and a partial defense of its import, namely, that no one is ever morally responsible or guilty for what they do and that many of the so-called reactive attitudes are misplaced. I focus primarily, though not exclusively, on the arguments as set out in Twilight of the Idols. First, there is Nietzsche's hypothesis, partly psychological and partly historical or anthropological, that the ideas of ‘free’ action or free (...) will, and of responsibility for actions freely chosen or willed, were introduced primarily in order to justify punishment. Call this the Genetic Thesis about Free Will. Second, there is Nietzsche's claim that the moral psychology, or ‘psychology of the will” as he calls it, that underlies this picture is, in fact, false – that, in fact, it is not true that every action is willed or that it reflects a purpose or that it originates in consciousness. Call these, in aggregate, the Descriptive Thesis about the Will. Finally, there is articulation of a programmatic agenda, namely, to restore the ‘innocence of becoming’ by getting rid of guilt and punishment based on guilt – not primarily because ascriptions of guilt and responsibility are false, but because a world understood as ‘innocent’, one understood in terms of ‘natural’ cause and effect, is a better world in which to live. I focus in particular on a reactive attitude often ignored by philosophers, but of crucial importance for Nietzsche, namely, revenge. I aim to explain and defend Zarathustra's recommendation: ‘Enemy’ you shall say, but not villain; sick you shall say, but not scoundrel; fool you shall say, but not ‘sinner.’ Nietzsche's views are contrasted with those of important modern writers on these topics, especially P.F. Strawson and Derk Pereboom. (shrink)

Do moral properties figure in the best explanatory account of the world? According to a popular realist argument, if they do, then they earn their ontological rights, for only properties that figure in the best explanation of experience are real properties. Although this realist strategy has been widely influential—not just in metaethics, but also in philosophy of mind and philosophy of science—no one has actually made the case that moral realism requires: namely, that moral facts really will figure in the (...) best explanatory picture of the world. This issue may have been neglected in part because the influential dialectic on moral explanations between philosophers Gilbert Harman and Nicholas Sturgeon has focused debate on whether moral facts figure in relevant explanations. Yet as others have noted, explanatory relevance is irrelevant when it comes to realism: after all, according to the popular realist argument, it is inference to the best explanation of experience that is supposed to confer ontological rights. I propose to ask, then, the relevant question about moral explanations: should we think that moral properties will figure in the best explanatory account of the world? (shrink)

I defend an inference to the best explanation (IBE) argument for anti-realism about reasons for acting based on the history of intractable disagreement in moral philosophy. The four key premises of the argument are: 1. If there were objective reasons for action, epistemically-well-situated observers would eventually converge upon them after two thousand years; 2. Contemporary philosophers, as the beneficiaries of two thousand years of philosophy, are epistemically well-situated observers; 3. Contemporary philosophers have not converged upon reasons for action; 4. Conclusion: (...) there are no objective reasons for action (IBE from the first three premises). The key premises of the IBE are (1) sentimentalism; (2) non-cognitivism about basic affects; and (3) philosophical arguments for what our reasons for action are always involve arguments that depend on a basic intuitive moral judgment (that can be explained in terms of a basic non-cognitive affect). All these premises are explored in detail, and various objections addressed. (shrink)

Este artigo apresenta a contribuição de Alcindo Flores Cabral (1907-1982) - professor de química da Faculdade de Agronomia Eliseu Maciel, hoje incorporada à Universidade Federal de Pelotas - ao ensino de química, uma contribuição quase desconhecida pela própria comunidade química brasileira, embora reconhecida como relevante por diversos químicos estrangeiros importantes, como W. Hückel, G. Charlot, F. Strong, E. Fessenden e outros. A inovadora representação helicoidal de Cabral é apresentada não só em conexão com representações contemporâneas, mas também inclui-se uma incursão (...) pelos primeiros sistemas helicoidais propostos, os de Hinrichs e de Baumhauer. Apresentam-se alguns comentários não somente sobre a Classificação natural dos elementos, publicada em 1946, mas também sobre outros textos escritos para tornar mais eficaz o ensino de química.

Augmented Reality (AR) is commonly defined as a digital layer of information viewed on top of the physical world through a smartphone, tablet or eyewear. Increasingly, this understanding of AR is shifting to a dynamic framework of ‘smart things’, including wearable technology, sensors and artificial intelligence (AI), with the ability to intercede in key moments and to deliver contextual and meaningful experiences. The things that come into context are the logical next steps in an evolutionary development towards computers that are (...) better able to show empathy in relation to people: even more human-oriented, anticipative and ubiquitous. Thus, this outsourcing of meaning to empathic technologies points to one of the fundamental questions concerning the relation of human and technology – the nature of the trust that users place in technology.
