This paper presents a version of neurophenomenology based on generative modelling techniques developed in computational neuroscience and biology. Our approach can be described as _computational phenomenology_ because it applies methods originally developed in computational modelling to provide a formal model of the descriptions of lived experience in the phenomenological tradition of philosophy (e.g., the work of Edmund Husserl, Maurice Merleau-Ponty, etc.). The first section presents a brief review of the overall project to naturalize phenomenology. The second section presents and evaluates (...) philosophical objections to that project and situates our version of computational phenomenology with respect to these projects. The third section reviews the generative modelling framework. The final section presents our approach in detail. We conclude by discussing how our approach differs from previous attempts to use generative modelling to help understand consciousness. In summary, we describe a version of computational phenomenology which uses generative modelling to construct a computational model of the inferential or interpretive processes that best explain this or that kind of lived experience.

Jonas Olson presents a critical survey of moral error theory, the view that there are no moral facts and so all moral claims are false. Part I explores the historical context of the debate; Part II assesses J. L. Mackie's famous arguments; Part III defends error theory against challenges and considers its implications for our moral thinking.

Moral particularism is commonly presented as an alternative to ‘principle- or rule-based’ approaches to ethics, such as consequentialism or Kantianism. This paper argues that particularists' aversions to consequentialism stem not from a structural feature of consequentialism per se, but from substantial and structural axiological views traditionally associated with consequentialism. Given a particular approach to value, there need be no conflict between moral particularism and consequentialism. We consider and reject a number of challenges holding that there is after all such a (...) conflict. We end by suggesting that our proposed position appears quite appealing since it preserves attractive elements from particularism as well as consequentialism. (shrink)

An enquiry into the relevance of Hans Jonas' thinking to present-day debates, including transhumanism, posthumanism, and human enhancement.

Jonas Olson defends a moral error theory in (2014). I will first argue that Olson is not justified in believing the error theory as opposed to moral nonnaturalism in his own opinion. I will then argue that Olson is not justified in believing the error theory as opposed to moral contextualism either (although the latter is not a matter of his own opinion).

Recognition and Freedom offers up-to-date discussions of Axel Honneth’s political thought by ten experts in the field. It also includes an interview with Honneth and an essay by him on education and democracy, previously unpublished in English.

Jonas Olson writes that "a plausible moral error theory must be an error theory about all irreducible normativity". I agree. But unlike Olson, I think we cannot believe this error theory. I first argue that Olson should say that reasons for belief are irreducibly normative. I then argue that if reasons for belief are irreducibly normative, we cannot believe an error theory about all irreducible normativity. I then explain why I think Olson's objections to this argument fail. I end (...) by showing that Olson cannot defend his view as a partly revisionary alternative to an error theory about all irreducible normativity. (shrink)

English summary: Hans Jonass Essais philosophiques are the most multidisciplinary of his works, covering ethics, the philosophy of nature, history, and the philosophy of religion. It also illustrates the path he cut through multiple fields of investigation. His debts to Heidegger and Spinoza are clear, as well as a common denominator for all of his philosophical research: the related concepts of freedom, will, and worth as factors of resistance against the threat of reductionism. French description: De tous les livres de (...) Hans Jonas, ce sont les Essais philosophiques qui ont le caractere le plus multidisciplinaire : ils portent sur l'ethique, la philosophie de la nature, de l'esprit, de l'histoire et la philosophie de la religion... Mais ce recueil n'est pas pour autant eclectique. Car au-dela de la diversite de ses objets, il constitue une remarquable illustration du chemin de pensee que s'est fraye le philosophe a travers des champs d'investigation multiples et apparemment heterogenes. C'est ainsi qu'au fil de textes qui furent publies entre Le Phenomene de la vie et Le principe responsabilite, on retrouve ici la dette du philosophe a l'egard de Heidegger, l'inspiration spinoziste de sa philosophie de la nature, les racines de son ethique de la responsabilite et un commun denominateur de toutes ses recherches philosophiques : les concepts apparentes de liberte, de volonte et de valeur qui animent sa pensee comme autant de facteurs de resistance a la menace du reductionnisme.

My aim in this essay is largely defensive. I aim to discuss some problems for moral error theory and to offer plausible solutions. A full positive defense of moral error theory would require substantial investigations of rival metaethical views, but that is beyond the scope of this essay. I will, however, try to motivate moral error theory and to clarify its commitments. Moral error theorists typically accept two claims – one conceptual and one ontological – about moral facts. The conceptual (...) claim is that moral facts are or entail facts about categorical reasons (and correspondingly that moral claims are or entail claims about categorical reasons); the ontological claim is that there are no categorical reasons – and consequently no moral facts – in reality. I accept this version of moral error theory and I try to unpack what it amounts to in Section 2.1 In the course of doing so I consider two preliminary objections: that moral error theory is (probably) false because its implications are intuitively unacceptable (what I call the Moorean objection) and that the general motivation for moral error theory is self-undermining in that it rests on a hidden appeal to norms. The above characterization seems to entail the standard formulation of moral error theory, according to which first-order moral claims are uniformly false. Critics have argued that the standard formulation is incoherent since – by the law of excluded middle – the negation of a false claim is true. Hence if ‘Torture is wrong’ is false, ‘Torture is not wrong’ is true. Contrary to what moral error theorists contend, then, moral error theory seems to carry first-order moral implications that by the theory’s own lights are uniformly false. In Section 3 I suggest a formulation that is consistent with the standard formulation of moral error theory, free of first-order moral implications, and subject to no logical difficulties. In Section 4 I consider and rebut Stephen Finlay’s recent attack on moral error theory. According to Finlay the conceptual claim is false because all moral claims – and indeed all normative claims – are, or should be understood as, relativized to some moral standard or system of ends. Moral error theorists thus attribute to ordinary speakers an error that simply isn’t there. I argue that Finlay’s view has some very implausible implications and that it does not avoid commitment to various forms of error theory. This becomes especially clear when we focus on fundamental moral claims. In Section 5 I consider the worry that error theorists’ rejection of categorical reasons proves too much; in particular, the worry that error theorists’ qualms about categorical reasons apply equally to claims about hypothetical reasons, that is, claims to the effect that there is reason to take the means to one’s ends. In my view error theorists such as Mackie and Joyce have failed to pay due consideration to this problem. What the challenge establishes, I submit, is that error theorists cannot just take for granted that hypothetical reasons are metaphysically unproblematic; they must offer an account of hypothetical reasons that shows that they are. I argue that the only plausible account available to error theorists is one according to which claims about hypothetical reasons reduce to non-normative claims about relations between means and ends.

Is the procreation asymmetry intuitively supported? According to a recent article in this journal, an experimental study suggests the opposite. Dean Spears (2020) claims that nearly three-quarters of participants report that there is a reason to create a person just because that person’s life would be happy. In reply, I argue that various confounding factors render the study internally invalid. More generally, I show how one might come to adopt the procreation asymmetry for the wrong reasons by misinterpreting one’s intuitions.

Hans Jonas bénéficie de la reconnaissance de ses pairs comme de la notoriété auprès d'un large public. L'auteur du " Principe responsabilité " est aussi un spécialiste de la religion gnostique, un philosophe de la vie analysant la dynamique de l'organisme et de l'esprit. La notion de liberté est un fil conducteur herméneutique pour exposer une pensée éclectique mais unitaire et originale.

The article endeavours to compare the reflections on the Shoah of two of the most celebrated intellectuals of Jewish origin of the 20th century, namely the German philosopher Hans Jonas and the Soviet writer Vasily Grossman. Both Jonas’ essay on The Concept of God after Auschwitz and Grossman’s novels and reports, such as The Hell of Treblinka, Life and Fate, and The Sistine Madonna, are characterised by a thorough enquiry into the ambivalence of the human condition, that tries (...) to shed some light on the disturbing abyss of Auschwitz and the Shoah. Although neither Jonas nor Grossman considered themselves as religious believers, thanks to the Shoah they recollected their Jewish roots and developed peculiar and innovative thoughts on the meaning and vulnerability of life, human freedom, immortality, and God. The article endeavours to highlight the main similarities and differences between these two authors, who tackled the issue of thinking after Auschwitz. (shrink)

This book explores the ways in which humor can enhance the learning environment. Drawing upon empirical research and brain-based concepts, Jonas presents a theoretical model of humor, along with practical examples for enhancing learning in schools and classrooms.

We will look critically at three essays by Cora Diamond concerning Peter Winch's views on the possibility of communication and criticism between language-games. We briefly present our understanding of Winch's approach to philosophy. Then, we argue that Diamond misidentifies Winch's views, taking them to imply language-game relativism or linguistic idealism. When she does raise valid criticisms against language-game relativism, her critical points mainly coincide with things that Winch has already stressed in his own work. That leaves us with the question (...) what their real disagreement amounts to. Finally, we suggest that at the bottom of Diamond's objections lies her failure to appreciate Winch's insights about the place of logic in human intercourse. (shrink)

Hans Jonas (1903–1993) was one of the most important German-Jewish philosophers of the 20th century. A student of Martin Heidegger and close friend of Hannah Arendt, Jonas advanced the fields of phenomenology and practical ethics in ways that are just beginning to be appreciated in the English-speaking world. Drawing here on unpublished and newly translated material, Lewis Coyne brings together for the first time in English Jonas's philosophy of life, ethic of responsibility, political theory, philosophy of technology (...) and bioethics. -/- In Hans Jonas: Life, Technology and the Horizons of Responsibility, Coyne argues that the aim of Jonas's philosophy is to confront three critical issues inherent to modernity: nihilism, the ecological crisis and the transhumanist drive to biotechnologically enhance human beings. While these might at first appear disparate, for Jonas all follow from the materialist turn taken by Western thought from the 17th century onwards, and he therefore seeks to tackle all three issues at their collective point of origin. This book explores how Jonas develops a new categorical imperative of responsibility on the basis of an ontology that does justice to the purposefulness and dignity of life: to act in a way that does not compromise the future of humanity on earth. -/- Reflecting on this, as we face a potential future of ecological and societal collapse, Coyne forcefully demonstrates the urgency of Jonas's demand that humanity accept its newfound responsibility as the 'shepherd of beings'.

Contextualism about vagueness (hereafter ‘Contextualism’) is the view that vagueness consists in a particular species of context-sensitivity and that properly accommodating this fact into our semantic theory will yield a plausible solution to the sorites paradox.[1],[2] But Contextualism, as many commentators have noted, faces the following immediate objection: if we hold the context fixed, vagueness still remains, therefore vagueness is not a species of context-sensitivity. Call this ‘the simple objection’.[3] Absent a convincing reply to the simple objection, Contextualism is in (...) very bad shape. Oddly enough, defenders of Contextualism have said very little in reply. Proponents of the objection have tended to assume that this is because no reply is in the offing—the simple objection is taken to be unassailable. In this short paper, we sketch two replies to the simple objection which result in two very different kinds of Contextualism: Epistemicist Contextualism and Radical Contextualism. With these two theories in hand, the simple objection loses its force. (shrink)

En la Biblia los magos pudieron replicar la hazaña de Aarón al transformar su cayado en una serpiente. Buenaventura sostiene que las serpientes no fueron producidas como el efecto de una intervención divina directa. Pedro Abelardo afi rma que esta historia muestra que no sabemos a ciencia cierta cómo distinguir los milagros de los acontecimientos mágicos. Por otro lado, en el Corán los magos no consiguen realmente replicar la hazaña de Moisés: solamente producen serpientes falsas. Por ello, Algazel prefi ere (...) no dar mucho peso a este milagro, precisamente por la difi cultad general que hay en distinguir los milagros de la magia. (shrink)

Philosophy of the Social Sciences, Volume 52, Issue 3, Page 150-174, June 2022. This article offers a reassessment of the main import of Peter Winch’s philosophy of the social sciences. Critics argue that Winch presented a flawed methodology for the social sciences, while his supporters deny that Winch’s work is about methodology at all. Contrary to both, the author argues that Winch deals with fundamental questions about methodology, and that there is something substantial to learn from his account. Winch engages (...) methodological questions without being committed to social ontology. Instead, Winch’s work on methodology is best described as a descriptive metaphysics of social inquiry. This alternative reading clarifies the close link between Winch’s argument for the autonomy of the social sciences and R. G. Collingwood’s philosophy of history. (shrink)

We discuss the idea that superpositions in quantum mechanics may involve contradictions or contradictory properties. A state of superposition such as the one comprised in the famous Schrödinger’s cat, for instance, is sometimes said to attribute contradictory properties to the cat: being dead and alive at the same time. If that were the case, we would be facing a revolution in logic and science, since we would have one of our greatest scientific achievements showing that real contradictions exist.We analyze that (...) claim by employing the traditional square of opposition.We suggest that it is difficult to make sense of the idea of contradiction in the case of quantum superpositions. From a metaphysical point of view the suggestion also faces obstacles, and we present some of them. (shrink)

Discussing Plato's views on knowledge, recollection, dialogue, and epiphany, this ambitious volume offers a systematic analysis of the ways that Platonic approaches to education can help students navigate today's increasingly complex moral environment. Though interest in Platonic education may have waned due to a perceived view of Platonic scholarship as wholly impractical, this volume addresses common misunderstandings of Plato's work and highlights the contemporary relevance of Plato's ideas to contemporary moral education. Building on philosophical interpretations, the book argues persuasively that (...) educators might employ Platonic themes and dialogue in the classroom. Split into two parts, the book looks first to contextualise Plato's theory of moral education within political, ethical, and educational frameworks. Equipped with this knowledge, part two then offers contemporary educators the strategies needed for implementing Plato's educational theory within the pluralistic, democratic classroom setting. A Platonic Theory of Moral Education will be of interest to academics, researchers, and post-graduate students in the fields of: ethics; Plato scholarship; moral psychology; educational foundations; and the philosophy of education. This book would also benefit graduate students and scholars in teacher education. Mark E. Jonas is Professor of Education and Professor of Philosophy at Wheaton College, US.

In this bold book, Jonas Grethlein proposes a new dialogue between the fields of Classics and aesthetics. Ancient material, he argues, has the capacity to challenge and re-orientate current debates. Comparisons with modern art and literature help to balance the historicism of classical scholarship with transcultural theoretical critique. Grethlein discusses ancient narratives and pictures in order to explore the nature of aesthetic experience. While our responses to both narratives and pictures are vicarious, the 'as-if' on which they are premised (...) is specifically shaped by the form of the representation. Form emerges as a key to how narratives and pictures constitute an important means of engaging with experience. Combining theoretical reflections with close readings, this book will appeal to art historians as well as to textual scholars. (shrink)

In this chapter, Jonas Ahlskog examines R. G. Collingwood’s conception of the philosophy of history and its metaphilosophical import. Ahlskog shows that Collingwood’s philosophy of history is simultaneously both a descriptive metaphysics of history and an elucidation of the relation between historical and philosophical thought. As a descriptive metaphysics, Ahlskog argues that Collingwood’s account has an irreducible and underexplored role for contemporary issues in the philosophy of history. The metaphilosophical import of Collingwood’s philosophy of history is unpacked through an (...) elaboration of Collingwood’s ideas about the historicity of human experience and understanding. In conclusion, Ahlskog argues that the metaphilosophical dimension of Collingwood’s philosophy of history is integrally connected with the concept of history as self-knowledge. (shrink)

Throughout his career, Hans Jonas has reflected on the notion of the human soul and on the concept of man being created in God’s image. A careful analysis of his writings reveals that (approximately) from 1968 he changed his perspective on these topics. Before this year, Jonas used some Gnostic myths to speak about the image of man in relation to God and was concerned that referring to the immortality of the human soul or to the notion of (...) imago Dei could lead to dualistic or pseudo-Gnostic interpretations of the natural world. From 1968 (when Jonas published an article for an American Jewish journal) he started to underline the importance of the Judeo-Christian notion of imago Dei (from the book of Genesis) for his ethical project. Subsequently, he used this concept (derived from the Bible rather than from Gnostic texts) in support of his ethical approach to show the special role that God assigned to humanity to act as a steward of His creation. This article presents the development of Jonas’s contributions on these issues over time, their importance in relation to his ethical project and how he was influenced in the development of his perspective on this subject.

The article deals with present day challenges related to the employ of technology in order to reduce the exposition of the human being to the risks and vulnerability of his or her existential condition. According to certain transhumanist and posthumanist thinkers, as well as some supporters of human enhancement, essential features of the human being, such as vulnerability and mortality, ought to be thoroughly overcome. The aim of this article is twofold: on the one hand, we wish to carry out (...) an enquiry into the ontological and ethical thinking of Hans Jonas, who was among the first to address these very issues with great critical insight; on the other hand, we endeavour to highlight the relevance of Jonas’ reflections to current challenges related to bioscience and biotechnological progress. In this regard, we believe that the transcendent and metaphysical relevance of the «image of man» introduced by Jonas is of paramount importance to understand his criticism against those attempts to ameliorate the human being by endangering his or her essence.

Following J.-Y.Béziau in his pioneer work on non-standard interpretations of the traditional square of opposition, we have applied the abstract structure of the square to study the relation of opposition between states in superposition in orthodox quantum mechanics in [1]. Our conclusion was that such states are contraries, contradicting previous analyzes that have led to different results, such as those claiming that those states represent contradictory properties. In this chapter we bring the issue once again into the center of the (...) stage, but now discussing the metaphysical presuppositions which underlie each kind of analysis and which lead to each kind of result, discussing in particular the idea that superpositions represent potential contradictions. We shall argue that the analysis according to which states in superposition are contrary rather than contradictory is still more plausible. (shrink)
