We consider an extended notion of reinforcement learning in which the environment can simulate the agent and base its outputs on the agent's hypothetical behavior. Since good performance usually requires paying attention to whatever things the environment's outputs are based on, we argue that for an agent to achieve on-average good performance across many such extended environments, it is necessary for the agent to self-reflect. Thus weighted-average performance over the space of all suitably well-behaved extended environments could be considered a (...) way of measuring how self-reflective an agent is. We give examples of extended environments and introduce a simple transformation which experimentally seems to increase some standard RL agents' performance in a certain type of extended environment.

I argue that a standard formulation of hinge epistemology is host to epistemic relativism and show that two leading hinge approaches (Coliva’s acceptance account and Pritchard’s nondoxastic account) are vulnerable to a form of incommensurability that leads to relativism. Building on both accounts, I introduce a new, minimally epistemic conception of hinges that avoids epistemic relativism and rationally resolves hinge disagreements. According to my proposed account, putative cases of epistemic incommensurability are rationally resolvable: hinges are propositions that are the objects (...) of our belief-like attitudes and are rationally revisable in virtue of our overarching commitment to avoid systematic deception in our epistemic practices.

I argue against the Standard View of ignorance, according to which ignorance is defined as equivalent to lack of knowledge, that cases of environmental epistemic luck, though entailing lack of knowledge, do not necessarily entail ignorance. In support of my argument, I contend that in cases of environmental luck an agent retains what I call epistemic access to the relevant fact by successfully exercising her epistemic agency and that ignorance and non-ignorance, contrary to what the Standard View predicts, are not (...) modal in the sense that knowledge is. After responding to objections, I conclude by sketching an alternative account of ignorance centered on the notions of epistemic access and epistemic agency. (shrink)

Una de las tesis que tradicionalmente han sido defendidas por la tradición del positivismo jurídico es la tesis coactiva, según la cual el derecho consiste en un conjunto de normas coactivas, en el sentido de impuestas por medio de la fuerza. Pero, sin abandonar esta corriente, ha habido históricamente diversas maneras de entender las relaciones entre derecho y fuerza. Si, pues, hasta comienzos del s. XX era opinión común la idea de que el derecho constituía un conjunto de mandatos o (...) normas de conducta cuya eficacia se garantizaba a través de la amenaza del uso de la fuerza coactiva a los transgresores de aquéllas; a lo largo del siglo pasado, empero, algunos autores muy destacados dieron en sostener la opinión de que la fuerza disponible por jueces y funcionarios venía a constituir sustancialmente el objeto mismo de toda regulación jurídica. Según esta última concepción, el derecho tendría primordialmente la función de articular las condiciones de legitimidad para el uso de la fuerza, designando a los sujetos a los que se encomienda tal uso y determinado los casos y modalidades en los que pueda utilizarse. Entre quienes sustentan la primera tesis, que afirma que la fuerza constituye la garantía del derecho, es lugar común citar a Austin y, a menudo, se cita también a Jhering. Entre los defensores de la segunda tesis común es habitual mencionar a Kelsen, Olivecrona y Ross, habiéndose sustanciado una polémica entre Bobbio y Olivecrona en punto a determinar si fuera menciona Olivecrona o fue Kelsen el primero en adoptarla. Sin embargo, es problemático incluir a Jhering dentro del primer grupo y no dentro del segundo, en cuyo caso habría que atribuirle la primera formulación histórica de la tesis. Este trabajo, de carácter histórico, parte de la citada polémica y trata de verificar la constancia de la segunda tesis en las obras no sólo de Kelsen y Olivecrona, sino sobre todo de Jhering.

Twenty-four of the world's most distinguished specialists provide brand-new essays about 'what there is': what kinds of things there are, and what relations hold among entities falling under various categories. They give the latest word on such topics as identity, modality, time, causation, persons and minds, freedom, and vagueness. The Handbook's unrivaled breadth and depth make it the definitive reference work (...) for students and academics across the philosophical spectrum. (shrink)

Este artigo apresenta um quadro conceitual para examinar a questão do especismo. Começa definindo-o como a consideração ou tratamento desfavorável injustificado daqueles que não pertencem a uma determinada espécie. A seguir, esclarece alguns dos mal-entendidos comuns acerca do que é e do que não é o especismo. Depois disso, argumenta contra a confusão entre (1) os diferentes modos em que se pode defender o especismo; e (2) as diferentes posições que assumem o especismo como uma de suas premissas. Dependendo se (...) essas últimas aceitam ou não outros critérios para a consideração moral à parte do especismo, podem ser posições especistas simples ou combinadas. Mas o especismo segue sendo em todos os casos a mesma ideia. Finalmente, este artigo examina o conceito de antropocentrismo, que define como o tratamento ou consideração desfavorável daqueles que não são membros da espécie humana. O conceito de antropocentrismo difere do de especismo e do de misoteria (animadversão para com os animais não humanos). Não obstante, pode-se concluir que o antropocentrismo é uma forma de especismo, à luz do que indicam, entre outros, o argumento da sobreposição de espécies e o argumento da relevância. (shrink)

Existen conceptos clave en las diversas ciencias (ya sean formales, naturales, biosociales o sociales) como “teoría” o “modelo” que están aún hoy sujetos a un amplio debate epistemológico, i.e. desde la teoría del conocimiento, y centrada en el estudio del conocimiento científico en particular. Los científicos, pues, construyen y utilizan diferentes nociones que cargan tras de sí realmente con un exhaustivo debate extracientífico sobre su naturaleza. En este trabajo se ofrecerán algunas aclaraciones y propuestas formales de definición sobre tales nociones (...) desde la filosofía de la ciencia del astrofísico y filosofo Gustavo Esteban Romero (G. E. Romero). En concreto se ensayaran unas definiciones formales de “teoría” y “modelo”, para las ciencias actuales (y otras disciplinas pasibles de su aplicación), y se contextualizarán estas ideas en el debate sobre la estructura y organización de los saberes científicos.

En su libro Una ética sin fundamentos, Nicolás Zavadivker sostiene que la teoría ética y metaética de Mario Bunge pretende fundamentar las normas morales en premisas fácticas, sin hacer uso de valores.

Dado que la teoría de Bunge incluye valores entre (...) sus premisas argumentativas, es incorrecto categorizarla como una posición fundacionista que prescinde de valores. (shrink)

Whipple disease is a rare, infectious, disease first described from a single case by Whipple in 1907. As well as characterising the clinical and pathological features of the condition, Whipple made two suggestions regarding its aetiology. These were either than the disease was caused by an infectious agent, or that it was of metabolic origin. As the disease is now thought to be caused by infection with the bacterium Tropheryma whipplei, historical reviews of the history of the disease typically mention (...) only the first of these suggestions. In this paper, we therefore revisit Whipple’s other theory. We argue that a diverse and often successful research programme was developed around this mechanism of disease causation which gave rise to many useful findings on the condition. In the later parts of this article, we then turn to discuss the surprising neglect of this period of Whipple disease research in the current literature, and conclude by offering a brief reconstruction of this early history suitable for use in a technical context.

En el presente trabajo se utiliza el problema ético de la automatización en transportes y vehículos dotados de inteligencia artificial (IA) para un análisis crítico de las diferentes posiciones éticas y morales clásicas. Debido a la intersección de la IA con los campos de investigación de la bioética, la nomoética y la tecnoética, existe un hilo conductor en sus fundamentos. Además, se juzga necesario para este propósito, así como por rigurosidad, hacer uso de una cantidad mínima de herramientas formales y (...) exponer un proyecto de una teoría ética actualizada, sistémica y materialista, que sobrepase a sus sistemas rivales. Así, se pretende ofrecer las bases para una teoría alterna más fecunda y explicar cómo las posiciones éticas tradicionales pueden ser obsoletas, si no directamente inaplicables, para afrontar la automatización inteligente y problemas morales similares, en la actualidad.

This paper defends a theory of hope according to which hopes are composed of a desire and a belief that the object of the desire is possible. Although belief plus desire theories of hope are now widely rejected, this is due to important oversights. One is a failure to recognize the relation that hope-constituting desires and beliefs must stand in to constitute a hope. A second is an oversimplification of the explanatory power of hope-constituting desires. The final portion of the (...) paper uses an enhanced understanding of the psychology of hope to make progress on normative questions about hoping well. (shrink)

According to a historically popular view, emotions are normative experiences that ground moral knowledge much as perceptual experiences ground empirical knowledge. Given the analogy it draws between emotion and perception, sentimental perceptualism constitutes a promising, naturalist-friendly alternative to classical rationalist accounts of moral knowledge. In this paper, we consider an important but underappreciated objection to the view, namely that in contrast with perception, emotions depend for their occurrence on prior representational states, with the result that emotions cannot give perceptual-like access (...) to normative properties. We argue that underlying this objection are several specific problems, rooted in the different types of mental states to which emotions may respond, that the sentimental perceptualist must tackle for her view to be successful. We argue, moreover, that the problems can be answered by filling out the theory with several independently motivated yet highly controversial commitments, which we carefully catalogue. The plausibility of sentimental perceptualism, as a result, hinges on further claims sentimental perceptualists should not ignore. (shrink)

This paper offers a qualified defense of a historically popular view that I call sentimental perceptualism. At a first pass, sentimental perceptualism says that emotions play a role in grounding evaluative knowledge analogous to the role perceptions play in grounding empirical knowledge. Recently, András Szigeti and Michael Brady have independently developed an important set of objections to this theory. The objections have a common structure: they begin by conceding that emotions have some important epistemic role to play, but then (...) go on to argue that understanding how emotions play that role means that there must be some alternative, emotion-independent route to obtaining knowledge of value. If there has to be such an emotion-independent route, then the perceptual analogy breaks down in a significant way. In this paper, I argue that the right ways for sentimental perceptualists to respond to each of these objections are revealed by thinking through how analogous objections applied to perception and the empirical domain would be answered. Although Szigeti's and Brady's objections should not persuade sentimental perceptualists to give up their view, the objections do put important constraints on what a form of the view has to be like in order to do exciting metaethical work.

Epistemic decision theory produces arguments with both normative and mathematical premises. I begin by arguing that philosophers should care about whether the mathematical premises (1) are true, (2) are strong, and (3) admit simple proofs. I then discuss a theorem that Briggs and Pettigrew (2020) use as a premise in a novel accuracy-dominance argument for conditionalization. I argue that the theorem and its proof can be improved in a number of ways. First, I present a counterexample that shows that one (...) of the theorem’s claims is false. As a result of this, Briggs and Pettigrew’s argument for conditionalization is unsound. I go on to explore how a sound accuracy-dominance argument for conditionalization might be recovered. In the course of doing this, I prove two new theorems that correct and strengthen the result reported by Briggs and Pettigrew. I show how my results can be combined with various normative premises to produce sound arguments for conditionalization. I also show that my results can be used to support normative conclusions that are stronger than the one that Briggs and Pettigrew’s argument supports. Finally, I show that Briggs and Pettigrew’s proofs can be simplified considerably. (shrink)

What role does the imagination play in scientific progress? After examining several studies in cognitive science, I argue that one thing the imagination does is help to increase scientific understanding, which is itself indispensable for scientific progress. Then, I sketch a transcendental justification of the role of imagination in this process.

This paper asks whether there is a moral virtue of hope, and if so, what it is. The enterprise is motivated by a historical asymmetry, namely that while Christian thinkers have long classed hope as a theological virtue, it has not traditionally been classed as a moral one. But this is puzzling, for hoping well is not confined to the sphere of religion; and consequently we might expect that if the theological virtue is structurally sound, there will be a secular, (...) moral analogue. This paper proposes that there is such an analogue, and that it is closely linked to the everyday notion of “having your priorities straight,” a phenomenon which is naturally understood in terms of the attitude of hope. It turns out that the priorities model provides an abstract way of characterizing a central but underexplored virtue, one which can be developed in secular or theological ways. (shrink)

This paper argues that Kant’s concept of ‘respect’ for the moral law has roots in Adam Smith’s concept of ‘regard’ for the general rules of conduct, which was translated as Achtung in the first German translation of the Theory of Moral Sentiments. After illustrating that Kant’s technical understanding of respect appeared relatively late in his intellectual development, I argue that Kant’s concept of respect and Smith’s concept of regard share a basic similarity: they are both a single complex phenomenon with (...) two core aspects, namely an attitude and a feeling. I then suggest that the concept of regard offered Kant a way to deal a problem concerning moral motivation that he was trying to solve at the time he likely first read Smith. I conclude by drawing some implications from the account I have offered for our understanding of Kant’s relation to Smith more generally. (shrink)

The fact that Gilbert Ryle and J.L. Austin seem to disagree about the ordinary use of words such as ‘voluntary’, ‘involuntary’, ‘voluntarily’, and ‘involuntarily’ has been taken to cast doubt on the methods of ordinary language philosophy. As Benson Mates puts the worry, ‘if agreement about usage cannot be reached within so restricted a sample as the class of Oxford Professors of Philosophy, what are the prospects when the sample is enlarged?’ (Mates, Inquiry 1:161–171, 1958, p. 165). In this chapter, (...) we evaluate Mates’s criticism alongside Ryle’s and Austin’s specific claims about the ordinary use of these words, assessing these claims against actual examples of ordinary use drawn from the British National Corpus (BNC). Our evaluation consists in applying a combination of methods: first aggregating judgments about a large set of samples drawn from the corpus, and then using a clustering algorithm to uncover connections between different types of use. In applying these methods, we show where and to what extent Ryle’s and Austin’s accounts of the use of the target terms are accurate as well as where they miss important aspects of ordinary use, and we demonstrate the usefulness of this new combination of methods. At the heart of our approach is a commitment to the idea that systematically looking at actual uses of expressions is an essential component of any approach to ordinary language philosophy. (shrink)

This article examines and rejects the view that nonhuman animals cannot be recipients of justice, and argues that the main reasons in favor of universal human rights and global justice also apply in the case of the international protection of the interests of nonhuman animals. In any plausible theory of wellbeing, sentience matters; mere species membership or the place where an animal is born does not. This does not merely entail that regulations of the use of animals aimed at reducing (...) their suffering should be implemented. It actually supports the end of such use, as well as other positive steps to provide help and to promote what is good not only for domesticated animals, but also for those living in the wild. Another reason to bring the protection of animals' interests into the international arena is that it is at this level that numerous animal exploitation industries enjoy the protection of different agreements and institutions. It does not follow from this that changing international law should be animal advocates' first priority, but it does follow that they should conduct their work internationally and not limit it to their own countries.

We seem to be able to acquire evaluative knowledge by mere reflection, or “from the armchair.” But how? This question is especially pressing for proponents of sentimental perceptualism, which is the view that our evaluative knowledge is rooted in affective experiences in much the way that everyday empirical knowledge is rooted in perception. While such empirical knowledge seems partially explained by causal relations between perceptions and properties in the world, in armchair evaluative inquiry, the relevant evaluative properties are typically not (...) even present. The paper shows how sentimental perceptualists can ultimately provide a broadly causal explanation of our reflective evaluative knowledge. (shrink)

Defends Kantian paternalism: Interference with an individual’s liberty for her own sake is justified absent her actual consent only to the extent that such interference stands a reasonable chance of preventing her from exercising her liberty irrationally in light of the rationally chosen ends that constitute her conception of the good. More specifically, interference with an individual’s liberty is permissible only if, by interfering, we stand a reasonable chance of preventing that agent from performing actions she chose due to distorted (...) reasoning and which would result in that agent’s rationally chosen ends not being as fully realized as they would have been had she so acted. -/- Applied to suicide intervention Kantian paternalism implies that such intervention is justified to the extent that it prevents a person from ending her life when, due to distorted reasoning, she engages in suicidal behavior that is at odds with her rationally chosen ends.

According to the received account of guilt in the philosophical literature, one cannot feel guilt unless one takes oneself to have done something morally wrong. But ordinary people feel guilt in many cases in which they do not take themselves to have done anything morally wrong. In this paper, I focus on one kind of guilt without perceived wrongdoing, guilt about being merely causally responsible for a bad state-of-affairs. I go on to present a novel account of guilt that explains (...) guilt about mere causal responsibility, according to which guilt represents part of the self as bound up with what is bad. (shrink)

Entiendo la acción filosófica como un proceso doble de crítica axiomática y construcción teórica. Cuando esta acción se aplica a las construcciones simbólicas de nuestra identidad, la llamo mitopoética. Por motivos evidentes, este libro no puede sino aspirar a ser el bosquejo de un mapa epistemológico a gran escala de las narraciones de la identidad humana, esquema que he dividido en tres partes. En las dos primeras, defino una estructura conceptual que será utilizada en la tercera para desarrollar una teoría (...) de la acción mítica. La primera es una introducción general a los problemas de la mitología tal y cómo han sido tratados desde el punto de vista de la filosofía de la religión, la lingüística, la historia, la estética y la epistemología, fundiendo todos en un concepto más general de antropología filosófica. La segunda parte está dedicada a la definición de las emociones y a la comprensión de su centralidad en relación a la racionalidad y la estructura de los mitos. A partir de los procesos de desarrollo semántico-emocional del lenguaje, construyo una teoría de la racionalidad continua, en la que los ritos animales son entendidos como protomitos, y los rituales y mitos humanos como un desarrollo simbólico enario de unos protocolos generales de supervivencia. Ambas partes son, entonces, una discusión sobre los elementos conceptuales necesarios para comprender las estructuras mítico-rituales, definidas y tratadas en la tercera sección, en la que defino las propiedades de las acciones miméticas interpretativas, o acciones míticas, y examino las diferentes configuraciones que han tomado a lo largo de nuestro desarrollo simbólico. El libro concluye con un análisis de los condicionamientos generales para el desarrollo de futuras estructuras míticas. Mi punto de partida ontoepistemológico es evolucionista, emergentista y constructivista, una postura que queda mejor expresada a partir de la teoría de la racionalidad continua, de inspiración aristotélica, que parte de que los procesos vitales muestran -en diferentes estados de complejidad- la propiedad de la inteligencia.

Call "radical moral theorizing" the project of developing a moral theory that not only tries to conform to our existing moral intuitions, but also manifests various theoretical virtues: consistency, simplicity, explanatory depth, and so on. Many moral philosophers assume that radical moral theorizing does not require any particular metaethical commitments. In this paper, I argue against this assumption. The most natural justification for radical moral theorizing presupposes moral realism, broadly construed; in contrast, there may be no justification for radical moral (...) theorizing if moral anti-realism is true.

The ‘Big 3’ theories of well-being—hedonism, desire-satisfactionism, and objective list theory—attempt to explain why certain things are good for people by appealing to prudentially good-making properties. But they don’t attempt to explain why the properties they advert to make something good for a person. Perfectionism, the view that well-being consists in nature-fulfilment, is often considered a competitor to these views (or else a version of the objective list theory). However, I argue that perfectionism is best understood as explaining why certain (...) properties are prudentially good-making. This version of perfectionism is compatible with each of the Big 3, and, I argue, quite attractive. (shrink)

The ‘black box’ in Stoic axiology refers to the mysterious connection between the input of Stoic deliberation (reasons generated by the value of indifferents) and the output (appropriate actions). In this paper, I peer into the black box by drawing an analogy between Stoic and Kantian axiology. The value and disvalue of indifferents is intrinsic, but conditional. An extrinsic condition on the value of a token indifferent is that one's selection of that indifferent is sanctioned by context-relative ethical principles. The (...) value of an indifferent that does not meet this condition is normatively silenced, such that it fails to constitute a reason for action. (shrink)

The methods of philosophical consultation vary enormously according to the practitioners who conceive and apply them. In this paper, we discuss the conceptions and methods we have been carrying out for several years in this field, such as philosophical naturalism, the dual requirement, first steps, anagogy and discrimination, thinking the unthinkable, switching to the "second floor", and being philosophical. Our methodology is mainly inspired by the Socratic maieutic, where the philosopher questions his interlocutor, invites him to identify the stakes of (...) his discourse, to conceptualize it by distinguishing key terms in order to implement them, to problematize it through a critical perspective, to universalize its implications. This practice has the specificity of inviting the subject to move away from a mere sensation to allow him a rational analysis of his speech and of himself, a sine qua non condition for deliberating on the cognitive and existential stakes which must be made explicit at first. The removal from oneself that this unnatural activity presupposes, for which it requires the assistance of a specialist, poses a certain number of difficulties, e.g., frustration, speech as a pretext, the issue of truth, pain and epidural. Finally, some additional exercises are very useful for the reflection process, such as establishing connections, real speech, order, universal and singular, and accepting the pathology. (shrink)

What is the status of research on implicit bias? In light of meta‐analyses revealing ostensibly low average correlations between implicit measures and behavior, as well as various other psychometric concerns, criticism has become ubiquitous. We argue that while there are significant challenges and ample room for improvement, research on the causes, psychological properties, and behavioral effects of implicit bias continues to deserve a role in the sciences of the mind as well as in efforts to understand, and ultimately combat, discrimination (...) and inequality.

This paper argues that there are two irreducibly distinct negative concepts of liberty: freedom as non-prevention, and freedom as non-coercion. Contemporary proponents of the negative view, such as Matthew Kramer and Ian Carter, have sought to develop the Hobbesian idea that freedom is essentially a matter of physical non-prevention. Accordingly, they have sought to reduce the freedom-diminishing effect of coercion to that of prevention by arguing that coercive threats function to diminish freedom by preventing people from performing certain combinations of (...) actions. Against this, this paper argues that coercion diminishes people’s freedom in ways that cannot be fully captured in terms of prevention. Focusing on two types of case, those involving coercive threats and those involving coercive preference manipulation, it argues that non-coercion and physical non-prevention are importantly different goods. It concludes that a complete negative account of liberty must draw not only on the (Hobbesian) ‘non-prevention’ strand of the negative tradition but also on its (Hayekian) ‘non-coercion’ strand.

This article offers a novel, conservative account of material constitution, one that incorporates sortal essentialism and features a theory of dominant sortals. It avoids coinciding objects, temporal parts, relativizations of identity, mereological essentialism, anti-essentialism, denials of the reality of the objects of our ordinary ontology, and other departures from the metaphysic implicit in ordinary ways of thinking. Defenses of the account against important objections are found in Burke 1997, 2003, and 2004, as well as in the often neglected six paragraphs (...) that conclude section V of this article. (shrink)

The philosophy of hope centers on two interlocking sets of questions. The first concerns the nature of hope. Specific questions here include how to analyze hope, how hope motivates us, and whether there is only one type of hope. The second set concerns the value of hope. Key questions here include whether and when it is good to hope and whether there is a virtue of hope. Philosophers of hope tend to proceed from the first set of questions to the (...) second. This is a natural approach, for one might expect that you must develop a basic understanding of what hope is before you can determine its value. The structure of this chapter thus follows this approach. But readers should not be misled: there is in fact a good deal of feedback between the two sets of questions. A theory of hope is more plausible to the extent that it fits well with plausible ideas about the value of hope. So the movement from hope’s nature to its value is one of emphasis rather than a strict, step-wise process. (shrink)

The causal premise of the evolutionary debunking argument contends that human moral beliefs are explained by the process of natural selection. While it is universally acknowledged that such a premise is fundamental to the debunker’s case, the vast majority of philosophers focus instead on the epistemic premise that natural selection does not track moral truth and the resulting skeptical conclusion. Recently, however, some have begun to concentrate on the causal premise. So far, the upshot of this small but growing literature (...) has been that the causal premise is likely false due to the seemingly persuasive evidence that our moral beliefs are in fact not the result of natural selection. In this paper, I argue that this view is mistaken. Specifically, I advocate the Innate Biases Model, which contends that there is not only compelling evidence for an evolved cognitive capacity for acquiring norms but also for the existence of an evolutionarily instilled set of cognitive biases that make it either more or less likely that we adopt certain moral beliefs.

Jaegwon Kim’s influential exclusion argument attempts to demonstrate the inconsistency of nonreductive materialism in the philosophy of mind. Kim’s argument begins by showing that the three main theses of nonreductive materialism, plus two additional considerations, lead to a specific and familiar picture of mental causation. The exclusion argument can succeed only if, as Kim claims, this picture is not one of genuine causal overdetermination. Accordingly, one can resist Kim’s conclusion by denying this claim, maintaining instead that the effects of the (...) mental are always causally overdetermined. I call this strategy the ‘ overdetermination challenge’. One of the main aims of this paper is to show that the overdetermination challenge is the most appropriate response to Kim’s exclusion argument, at least in its latest form. I argue that Kim fails to adequately respond to the overdetermination challenge, thus failing to prevent his opponents from reasonably maintaining that the effects of the mental are always causally overdetermined. Interestingly, this discussion reveals a curious dialectical feature of Kim’s latest response to the overdetermination challenge: if it succeeds, then a new, simpler and more compact version of the exclusion argument is available. While I argue against the consequent of this conditional, thereby also rejecting the antecedent, this dialectical feature should be of interest to philosophers on either side of this debate.

Drawing on work from Marina Sbisà’s “Ideology and the Persuasive Use of Presupposition” (1999), Rae Langton has developed a powerful account of the subtle mechanisms through which hate speech and propaganda spread. However, this model has a serious limitation: it focuses too strongly on individual speech acts isolated from their wider context, rendering its applicability to a broader range of cases suspect. In this chapter, I consider the limits of presupposition accommodation to clarify the audience’s role in helping hate speakers, (...) and claim the necessary mechanisms are much more active and social than Langton suggests, with effects not capturable in the analysis of isolated speech acts. I revisit Sbisà’s work on presupposition and develop an alternative model that (1) improves upon the Langtonian model for explaining the power of hate propaganda, and (2) is more in line with Sbisà’s original approach to ideology and the normative aspects of presupposition.

The properties of angular momentum and its connection to magnetic momentum are explored, based on a reconsideration of the Stern-Gerlach experiment and gauge invariance. A possible way to solve the so called spin crisis is proposed.

A proof is given that, for systems of more than two particles, un- less all of (...) them have the same mass, the possibility of having eigenvalues of the form (n + 1/2)h is not excluded. (shrink)

I propose a framework, derived from moral theory, for assessing the moral status of intelligent machines. Using this framework, I claim that some current and foreseeable intelligent machines have approximately as much moral status as plants, trees, and other environmental entities. This claim raises the question: what obligations could a moral agent (e.g., a normal adult human) have toward an intelligent machine? I propose that the threshold for any moral obligation should be the "functional morality" of Wallach and Allen [20], (...) while the upper limit of our obligations should not exceed the upper limit of our obligations toward plants, trees, and other environmental entities.
