When learners self-explain, they try to make sense of new information. Although research has shown that bodily actions and written notes are an important part of learning, previous analyses of self-explanations rarely take into account written and non-verbal data produced spontaneously. In this paper, the extent to which interpretations of self-explanations are influenced by the systematic consideration of such data is investigated. The video recordings of 33 undergraduate students, who learned with worked-out examples dealing with complex numbers, were categorized successively (...) including three different data bases: verbal data, verbal and written data, and verbal, written and non-verbal data. Results reveal that including written data and non-verbal data leads to a more accurate analysis of self-explanations than an analysis solely based on verbal data. This influence is even stronger for the categorization of self-explanations as adequate or inadequate. (shrink)

It is agreed by most scholars that the Stoics were compatibilists regarding the relation between responsibility and determinism. On this view, the Stoics depart from two other positions. Unlike some eliminative determinists — labelled in modern discussions “hard-determinists”, but already active in Antiquity — they assert that, despite determinism, there are things that “depend on us”, or are : things for which we are genuinely responsible and for which, therefore, we may justifiably be praised or blamed. But the Stoics also (...) depart from the libertarian or “anti-determinist” 2 a position championed by the Epicureans in the early Hellenistic period and by Alexander of Aphrodisias on behalf of the Peripatetics, towards the end of the second century AD. Unlike the libertarian, who agrees on the incompatibility alleged by the hard-determinist, but preserves responsibility by rejectin necessitation, the Stoics preserve both responsibility and necessitation.

La contribución de Ricardo Salles se centra en la interpretación peripatética de Alejandro en contra de la tesis estoica de que la lógica no es “instrumento”, sino “parte” de la filosofía. Según Alejandro, si la lógica fuera parte de la filosofía, como pretenden los estoicos, la filosofía no podría ocupar el lugar más elevado en la jerarquía del conocimiento; pero esto sería, en cierto modo, paradójico, argumenta Salles, pues todos –tanto estoicos como peripatéticos– consideran, por diversas razones, que la filosofía (...) es, por su objeto, la disciplina más elevada. De acuerdo con Salles, sin embargo, esta aguda crítica no es lo suficientemente penetrante para poner de manifiesto una verdadera inconsistencia en el estoicismo. Salles cree que esto sería paradójico, pues todos –tanto estoicos como peripatéticos– consideran, por diversas razones, que la filosofía es, por su objeto, la disciplina más elevada. De acuerdo con Salles, sin embargo, la aguda crítica de Alejandro no es lo suficientemente penetrante para poner de manifiesto una verdadera inconsistencia en el estoicismo. Su principal debilidad, en su opinión, radica en el hecho de que el razonamiento sobre el cual descansa depende de supuestos aristotélicos que los estoicos rechazan. (shrink)

Review of Salles, R.; Molina Ayala, J. Alejandro de Afrodisia. _De la mixtura y el crecimiento_.

The ἐκπύρωσις, or world's conflagration, followed by the restoration of an identical world seems to go against the rationality of the Stoic god. The aim of this paper is to show that Cleanthes, the second head of the School, can avoid this paradox. According to Cleanthes, the conflagration is an inevitable side-effect of the necessary means used by god to sustain the world. Given that this side-effect is contrary to god's sustaining activity, but unavoidable, god's rationality requires the restoration of (...) an identical world once the conflagration subsides. The paper also deals with the relation between Cleanthes and other early Stoics on the topic of conflagration. In particular, Cleanthes' position seems to differ from Chrysippus'. For in contrast with the Cleanthean god, who causes the conflagration as a side-effect only, the Chrysippean god, according to an influential interpretation put forward by Jaap Mansfeld, causes the conflagration as his ultimate cosmological goal.

Usamos cotidianamente um conjunto de expressões para captar, selecionar ou referir uma determinada coisa particular e podermos em seguida dizer algo sobre essa coisa. Expressões desse tipo incluem nomes próprios, como “Platão” ou “João”, descrições definidas, como “o rei da França” ou “o autor da República”, demonstrativos, como “este” ou “isto”, etc. O uso cotidiano de tais expressões pode parecer não envolver problema filosófico algum. Afinal, o que poderia haver de mais banal? Mas, infelizmente (ou felizmente?) há problemas filosóficos dificílimos (...) envolvidos aí. Bertrand Russell notou isso, e desenvolveu uma curiosa análise das expressões do segundo tipo mencionado, estendendo-a, posteriormente, às do primeiro tipo. Russell pensava que se a sua análise estivesse correta, seria capaz de resolver um conjunto de problemas filosóficos que vão da filosofia da linguagem à metafísica. O principal objetivo deste trabalho é propor uma introdução acessível a essa análise, conhecida como Teoria das Descrições, sem esquecer o número gigantesco de críticas e defesas levantadas a favor e contra ela.

The recently published BRAIN 2.0 Neuroethics Report offers a very helpful overview of the possible ethical, social, philosophical, and legal issues raised by neuroscience in the context of BRAIN’s research priorities thus contributing to the attempt to develop ethically sound neuroscience. In this article, we turn to a running theme of the document: the need for an ethical framework for the BRAIN Initiative and for further integration of neuroethics and neuroscience. We assess some of the issues raised and provide an (...) explanation of how we have addressed them in the Human Brain Project. We offer our experience in the HBP as a potential contribution to the international debate about neuroethics in the big brain initiatives. Our hope is that among other things, the type of exchange proposed by this AJOB special issue will prove productive in further identifying and discussing the issues and in inspiring appropriate solutions.

O objetivo deste texto é, primeiramente, expor os contornos gerais as críticas de David Hume ao que o filósofo escocês chamou epicurismo moderno. Trata-se das filosofias de Hobbes e de seus supostos epígonos, que, aos olhos de Hume, elegeram o amor próprio como origem fundamental de nossas ações e juízos. Num segundo momento, trata-se de delinear o lugar central do conceito de simpatia nesta crítica, bem como na constituição da moral humeana.

This book proposes a new solution to the problem of vagueness. There are several different ways of addressing this problem and no clear agreement on which one is correct. The author proposes that it should be understood as the problem of explaining vague predicates in a way that systematizes six intuitions about the phenomenon and satisfies three criteria of adequacy for an ideal theory of vagueness. The third criterion, which is called the “criterion of precisification”, is the most controversial one. (...) It is based on the intuition that a predicate is vague only if it is imprecise. The author considers some different definitions of linguistic imprecision, proposing that a predicate is imprecise if and only if there is no sharp boundary between objects to which its application yields some particular truth-value and objects to which its application does not yield that truth-value. The volume critically reviews the current theories of vagueness and proposes a new one, the Theory of Vagueness as Arbitrariness, which defines a vague predicate as an arbitrary predicate that must be precisified in order to contribute to a sentence that has truth-conditions. The main advantages of this theory over the current alternatives are that it satisfies all three criteria and systematizes the relevant intuitions. (shrink)

Com isto ele pretende atacar algumas noções de Kripke sobre coisas concretas e nomes próprios. (shrink)

Recently, some have proposed moral bioenhancement as a solution to the serious moral evils that humans face. Seemingly disillusioned with traditional methods of moral education, proponents of bioenhancement believe that we should pursue and apply biotechnological means to morally enhance human beings. Such proposal has generated a lively debate about the permissibility of moral bioenhancement. We argue here that such debate is specious. The claim that moral bioenhancement is a solution – whether permissible or not – to the serious moral (...) problems that affect human beings is based on several problematic framing assumptions. We evaluate here three of such assumptions: the first rests on a contested understanding of morality, the second consist in a mistaken conception of human moral problems, and the third relates to problematic presuppositions grounding the interpretation of existent scientific evidence presented to defend moral bioenhancement. Once these framing assumptions are identified and critically evaluated, it becomes clear that the moral bioenhancement debate is misguided. (shrink)

Within the last decades, brain science has been offering new insights into the relationship among diverse psychological processes and the neural correlates of our moral thought and behavior. Despite the distinction between the explanatory/descriptive nature of science and the normative nature of morality, some neuroethicists have claimed that neuroscientific findings have normative implications. In this paper, I identify three interpretations of the claim. The first focuses on neuroscience’s role in explaining the origin of morality and of moral values and how (...) neurobiology is the bases of moral behavior. A second version is about the role that neuroscientific knowledge can play in showing the psychological plausibility of the moral psychology underlying some ethical approaches. Finally, a third version advances that neuroscience could play a role in determining the moral plausibility of some normative approaches. My aim is to delineate each version and highlight the issues raised to suggest that while neuroscience might provide information regarding the nature of moral reasoning, its role in the normative discussion itself is still quite limited.

AI research is growing rapidly raising various ethical issues related to safety, risks, and other effects widely discussed in the literature. We believe that in order to adequately address those issues and engage in a productive normative discussion it is necessary to examine key concepts and categories. One such category is anthropomorphism. It is a well-known fact that AI’s functionalities and innovations are often anthropomorphized. The general public’s anthropomorphic attitudes and some of their ethical consequences have been widely discussed in (...) the literature. However, how anthropomorphism permeates AI research itself, and what the epistemological and ethical consequences of this might be have received less attention. In this paper we explore this issue. We first set the methodological/theoretical stage, making a distinction between a normative and a conceptual approach to the issues. Next, after a brief analysis of anthropomorphism and its manifestations in the public, we explore its presence within AI research with a particular focus on brain-inspired AI. Finally, on the basis of our analysis, we identify some potential epistemological and ethical consequences of the use of anthropomorphic language and discourse within the AI research community, thus reinforcing the need of complementing the practical with a conceptual analysis.

There is a growing resurgence in the study of psychedelic medicines for the treatment of mental health and substance use disorders. However, certain early investigations are marred by questionable research methods, abuses against research participants, and covert Central Intelligence Agency financial involvement. The purpose of this study was to understand how and to what extent people of colour and other vulnerable populations, specifically, individuals who were incarcerated or incapacitated due to mental health issues, were exploited during the first wave of (...) psychedelic research in the USA. To do so, we reviewed available empirical publications according to current ethical standards. Variables of interest included race and ethnicity of participants, population vulnerability, drug administration conditions, informed consent and undue influence. Our findings draw attention to the history of research abuses against people of colour in Western psychedelic research. In light of these findings, we urge a call-to-action to current psychedelic researchers to prioritise culturally inclusive and socially responsible research methods in current and future studies. All data relevant to the study are included in the article. (shrink)

While it might seem prima facie plausible that divine foreknowledge is all that is needed for prophecy, this seems incorrect. To issue a prophecy, God hasto know not just how someone will act, but how someone would act were the prophecy issued. This makes some think that Middle Knowledge is required.I argue that Thomas Flint’s two Middle Knowledge based accounts of prophecy are unsatisfactory, but one of them can be repaired. However the resources needed for repair also yield a sketch (...) of a foreknowledge-only account of prophecy. (shrink)

Este artigo trata de três objeções à teoria do propósito. Essa teoria afirma que o único sentido que a nossa vida pode ter é satisfazer um propósito que Deus nos atribuiu. A primeira objeção que trabalharei afirma que seria incompatível com a bondade de Deus que Ele nos punisse por não cumprirmos o seu propósito. A segunda sugere que a oferta de um céu por cumprirmos o seu propósito seria ofensiva, poderia ser encarada como exploração. Por fim, a última é (...) a acusação feita por Kurt Baier de que o próprio fato de Deus nos atribuir um propósito seria ofensivo. Metz responde a essas três acusações em seu artigo "Poderá o propósito de Deus ser a única fonte de sentido para a vida?" acreditando escapar dessas acusações. Meu objetivo é mostrar que, embora Metz escape das duas primeiras, sua resposta ao argumento de Baier leva-o a ter que aceitar que Deus é injusto. (shrink)

Explanations are very important to us in many contexts: in science, mathematics, philosophy, and also in everyday and juridical contexts. But what is an explanation? In the philosophical study of explanation, there is long-standing, influential tradition that links explanation intimately to causation: we often explain by providing accurate information about the causes of the phenomenon to be explained. Such causal accounts have been the received view of the nature of explanation, particularly in philosophy of science, since the 1980s. However, philosophers (...) have recently begun to break with this causal tradition by shifting their focus to kinds of explanation that do not turn on causal information. The increasing recognition of the importance of such non-causal explanations in the sciences and elsewhere raises pressing questions for philosophers of explanation. What is the nature of non-causal explanations – and which theory best captures it? How do non-causal explanations relate to causal ones? How are non-causal explanations in the sciences related to those in mathematics and metaphysics? This volume of new essays explores answers to these and other questions at the heart of contemporary philosophy of explanation. The essays address these questions from a variety of perspectives, including general accounts of non-causal and causal explanations, as well as a wide range of detailed case studies of non-causal explanations from the sciences, mathematics and metaphysics.

We talk as if there are natural kinds and in particular we quantify over them. We can count the number of elements discovered by Sir Humphrey Davy, or the number of kinds of particle in the standard model. Consequently, it looks at first sight at least, that natural kinds are entities of a sort. In the light of this we may ask certain questions: is the apparent existence of natural kinds real or an illusion? And if real, what sort of (...) entity are natural kinds? Are they sui generis? Or can they be identified with or reduced to some other kind of entity? In this essay I shall look at possible reasons for asserting that either kinds are no sort of entity, or, if they are entities, their existence is equivalent to some fact not involving kinds. Richard Boyd seems to take the view that the apparent existence of natural kinds is an illusion. (shrink)

Toy models are highly idealized and extremely simple models. Although they are omnipresent across scientific disciplines, toy models are a surprisingly under-appreciated subject in the philosophy of science. The main philosophical puzzle regarding toy models concerns what the epistemic goal of toy modelling is. One promising proposal for answering this question is the claim that the epistemic goal of toy models is to provide individual scientists with understanding. The aim of this article is to precisely articulate and to defend this (...) claim. In particular, we will distinguish between autonomous and embedded toy models, and then argue that important examples of autonomous toy models are sometimes best interpreted to provide how-possibly understanding, while embedded toy models yield how-actually understanding, if certain conditions are satisfied. _1_ Introduction _2_ Embedded and Autonomous Toy Models _2.1_ Embedded toy models _2.2_ Autonomous toy models _2.3_ Qualification _3_ A Theory of Understanding for Toy Models _3.1_ Preliminaries and requirements _3.2_ The refined simple view _4_ Two Kinds of Understanding with Toy Models _4.1_ Embedded toy models and how-actually understanding _4.2_ Against a how-actually interpretation of all autonomous toy models _4.3_ The how-possibly interpretation of some autonomous toy models _5_ Conclusion.

This Is A New Release Of The Original 1868 Edition.

Responsible Research and Innovation (RRI) is an important ethical, legal, and political theme for the European Commission. Although variously defined, it is generally understood as an interactive process that engages social actors, researchers, and innovators who must be mutually responsive and work towards the ethical permissibility of the relevant research and its products. The framework of RRI calls for contextually addressing not just research and innovation impact but also the background research process, specially the societal visions underlying it and the (...) norms and priorities that shape scientific agendas. This requires the integration of anticipatory, inclusive, and responsive dimensions, and the nurturing of a certain type of reflexivity among a variety of stakeholders, from scientists to funders. In this paper, we do not address potential limitations but focus on the potential contribution of philosophical reflection to RRI in the context of the Ethics and Society subproject of the Human Brain Project (HBP). We show how the type of conceptual analysis provided by philosophically oriented approaches theoretically and ethically broadens research and innovation within the HBP. We further suggest that overt inclusion of philosophical reflection can promote the aims and objectives of RRI. (shrink)

The attempt to convene a discussion about childhood suggests a plurality of educative issues and raises important problems in the context of basic education. To recognize children in their specificity, and to engage and encounter them beyond the discourses produced about them seems to be a challenge today, most especially in the field of childhood education. The large majority of educational discourses assume a notion of childhood as inserted in chronological time, associated with the future, and constituting a doubtful minority. (...) The objective of this paper is to understand what significations and meanings are configuring the discursive practices maintained among teachers about the childhood.I start with the hypothesis that, despite the reconstitution of meaning that has occurred in the field, educators still associate the concept of childhood and its formation with the idea of becoming adult, and presume to explain the notion of childhood technically, in terms of a body of “scientific” knowledge. The research described here is based on an inquiry that took place in various Childhood Education Centers of the Public Municipal Network of the state of Pernambuco, Brazil. Although it is unfinished, this research, based on interviews, suggests that teacher discourses inhabit two discursive temporalities, and two childhoods: on the one side, the affirmation of the same, of unification, of linearity; on the other, the affirmation of difference, of novelty, of the singular. Although they enunciate different meanings for childhood, these meanings are not in themselves contradictory. They do, however, function in some way to maintain a form of schooling that lacks sensitivity to children and a more affirmative relationship to childhood in general, and which encloses itself in an adult vision of what children’s needs might be the. I try to show that those needs exceed the specificity of the teaching and learning typically encountered in schools, and to evaluate to what extent they are affirmed by scholarly notions of childhood.

The present paper studies a family of Stoic proofs of the intelligence of the cosmos, i. e. of the thesis that the cosmos is intelligent in the strong sense that it is, as a whole, something that thinks. This family, ‘F2’, goes back to a proof, ‘XP’, found in Philebus 29a9–30 a8 and Xenophon Mem. 1.4.8. F2 infers the intelligence of the cosmos, as XP does, from the general idea that our intelligence proceeds from the cosmos, which is the ultimate (...) cause of why we are intelligent, and the further claim that, since this is so, the cosmos itself must be intelligent. They differ from one another, however, in how they account for. In this paper, I present a new reason for why the accounts are different, that complements those given by David Sedley in a recent and important study of Stoic cosmology. Based on the analogy between intelligence and the four elements, XP puts forward the idea that the intelligence currently present in us is a portion of cosmic intelligence that has separated from it at some point in the past, and that has travelled from the outside cosmos to us. In contrast, the theory used by F2 to explain the generation of human intelligence is grounded not in the notions of separation and locomotion, but in that of transmission of a state. As I argue in some detail, the separation-locomotion model and the transmission model are not only different from each other, but also logically independent from one another: in general terms, neither entails the other. This transmission model used by the Stoics in a proof of the intelligence of the cosmos, I submit, is a major innovation in ancient cosmological and metaphysical thinking. (shrink)

Laws of nature take center stage in philosophy of science. Laws are usually believed to stand in a tight conceptual relation to many important key concepts such as causation, explanation, confirmation, determinism, counterfactuals etc. Traditionally, philosophers of science have focused on physical laws, which were taken to be at least true, universal statements that support counterfactual claims. But, although this claim about laws might be true with respect to physics, laws in the special sciences (such as biology, psychology, economics etc.) (...) appear to have—maybe not surprisingly—different features than the laws of physics. Special science laws—for instance, the economic law “Under the condition of perfect competition, an increase of demand of a commodity leads to an increase of price, given that the quantity of the supplied commodity remains constant” and, in biology, Mendel's Laws—are usually taken to “have exceptions”, to be “non-universal” or “to be ceteris paribus laws”. How and whether the laws of physics and the laws of the special sciences differ is one of the crucial questions motivating the debate on ceteris paribus laws. Another major, controversial question concerns the determination of the precise meaning of “ceteris paribus”. Philosophers have attempted to explicate the meaning of ceteris paribus clauses in different ways. The question of meaning is connected to the problem of empirical content, i.e., the question whether ceteris paribus laws have non-trivial and empirically testable content. Since many philosophers have argued that ceteris paribus laws lack empirically testable content, this problem constitutes a major challenge to a theory of ceteris paribus laws. (shrink)

The goal of this paper is to develop a counterfactual theory of explanation. The CTE provides a monist framework for causal and non-causal explanations, according to which both causal and non-causal explanations are explanatory by virtue of revealing counterfactual dependencies between the explanandum and the explanans. I argue that the CTE is applicable to two paradigmatic examples of non-causal explanations: Euler’s explanation and renormalization group explanations of universality.

The Principle of Sufficient Reason says that all contingent facts must have explanation. In this 2006 volume, which was the first on the topic in the English language in nearly half a century, Alexander Pruss examines the substantive philosophical issues raised by the Principle Reason. Discussing various forms of the PSR and selected historical episodes, from Parmenides, Leibnez, and Hume, Pruss defends the claim that every true contingent proposition must have an explanation against major objections, including Hume's imaginability argument (...) and Peter van Inwagen's argument that the PSR entails modal fatalism. Pruss also provides a number of positive arguments for the PSR, based on considerations as different as the metaphysics of existence, counterfactuals and modality, negative explanations, and the everyday applicability of the PSR. Moreover, Pruss shows how the PSR would advance the discussion in a number of disparate fields, including meta-ethics and the philosophy of mathematics. (shrink)

:In this article, we begin by identifying three main neuroethical approaches: neurobioethics, empirical neuroethics, and conceptual neuroethics. Our focus is on conceptual approaches that generally emphasize the need to develop and use a methodological modus operandi for effectively linking scientific and philosophical interpretations. We explain and assess the value of conceptual neuroethics approaches and explain and defend one such approach that we propose as being particularly fruitful for addressing the various issues raised by neuroscience: fundamental neuroethics.

Ethical reflection on Artificial Intelligence has become a priority. In this article, we propose a methodological model for a comprehensive ethical analysis of some uses of AI, notably as a replacement of human actors in specific activities. We emphasize the need for conceptual clarification of relevant key terms in order to undertake such reflection. Against that background, we distinguish two levels of ethical analysis, one practical and one theoretical. Focusing on the state of AI at present, we suggest that regardless (...) of the presence of intelligence, the lack of morally relevant features calls for caution when considering the role of AI in some specific human activities.

ABSTRACT It has become standard to conceive of metalinguistic disagreement as motivated by a form of negotiation, aimed at reaching consensus because of the practical consequences of using a word with one content rather than another. This paper presents an alternative motive for expressing and pursuing metalinguistic disagreement. In using words with given criteria, we betray our location amongst social categories or groups. Because of this, metalinguistic disagreement can be used as a stage upon which to perform a social identity. (...) The ways in which metalinguistic disagreements motivated in this way diverge in character from metalinguistic negotiations are described, as are several consequences of the existence of metalinguistic disagreements motivated in this way.

In this paper I will argue that to accept the principle of tolerance does not provide us with a good explanation of the phenomena of vagueness. I will be mainly concerned with the incoherentist strategy, which accepts tolerance and the consequent incoherence of vague predicates. In fact, incoherentism seems to be the most plausible way of accepting tolerance. Because of this, the rejection of incoherentism might be seen as a way to rescue the alternative theories from the objection that they (...) do not respect the principle of tolerance as a literal truth about vagueness. Despite this, I will conclude that neither incoherentism nor the main alternatives satisfy the criteria for an ideal theory of vagueness. (shrink)

O paradoxo consiste no fato de que Hobbes teria reivindicado descobertas que a sua teoria implica que não poderiam ser feitas.

Evans famosamente declarou que Frege não aceitou a possibilidade de sentido sem referente, o que significa que ele não foi tão tolerante com nomes vazios quanto comumente se pensa. Um problema central para a tese de Evans é que Frege diz explicitamente que aceita esta possibilidade, e parece que ele de fato foi tolerante com nomes vazios. Neste artigo, defendo que a solução de Evans para este problema implica que Frege estava comprometido com uma explicação implausível das frases contendo nomes (...) vazios. (shrink)
