Bill D'Alessandro talks to Kenny Easwaran about fractal music, Zoom conferences, being a good referee, teaching in math and philosophy, the rationalist community and its relationship to academia, decision-theoretic pluralism, and the city of Manhattan, Kansas.

Naive versions of decision theory take probabilities and utilities as primitive and use expected value to give norms on rational decision. However, standard decision theory takes rational preference as primitive and uses it to construct probability and utility. This paper shows how to justify a version of the naive theory, by taking dominance as the most basic normatively required preference relation, and then extending it by various conditions under which agents should be indifferent between acts. The resulting theory can make (...) all the decisions of classical expected utility theory, plus more in cases where expected utilities are infinite or undefined. Although the theory requires similarly strong assumptions to classical expected utility theory, versions of the theory can be developed with slightly weaker assumptions, without having to prove a new representation theorem for the weaker theory. This alternate foundation is particularly useful if probability is prior to preference, as suggested by the recent program to base probabilism on accuracy and alethic considerations rather than pragmatic ones.

This revised edition of Sir Anthony Kenny’s classic work on Wittgenstein contains a new introduction which covers developments in Wittgenstein scholarship since the book was first published. Widely praised for providing a lucid and historically informed account of Wittgenstein’s core philosophical concerns. Demonstrates the continuity between Wittgenstein’s early and later writings. Provides a persuasive argument for the unity of Wittgenstein’s thought. Kenny also assesses Wittgenstein’s influence in the latter part of the twentieth century.

Based on the Wilde Lectures in Natural Religion given by Anthony Kenny at Oxford from 1970 to 1972, here revised in light of recent discussion and reflection, this provocative book examines some of the principal attributes traditionally ascribed to God in western theism, particularly omniscience and omnipotence. From his discussion of a number of related topics, including a comprehensive treatment of the problem of the relations between divine foreknowledge and human freedom, Kenny concludes that there can be no (...) such being as the God of traditional natural theology.

Anthony Kenny offers a critical examination of Thomas Aquinas's influential account of being, arguing that it suffers from systematic confusion. Because of the centrality of the doctrine, this has implications for other parts of Aquinas's philosophical system. Kenny's clear and incisive study dispels the confusion and offers philosophers and theologians a guide through the labyrinth of Aquinas's ontology.

Written by Anthony Kenny, a leading figure in contemporary philosophy, this volume guides the reader through a concise and accessible explanation and assessment of Frege's radical and lasting contributions to our understanding of language, meaning, and the foundations of arithmetic.

Conditional probability is one of the central concepts in probability theory. Some notion of conditional probability is part of every interpretation of probability. The basic mathematical fact about conditional probability is that p(A |B) = p(A ∧B)/p(B) where this is defined. However, while it has been typical to take this as a definition or analysis of conditional probability, some (perhaps most prominently Hájek, 2003) have argued that conditional probability should instead be taken as the primitive notion, so that this formula (...) is at best coextensive, and at worst sometimes gets it wrong. -/- Section 1.1 considers the concept of conditional probability in each of the major families of interpretation of probability. Section 1.2 considers a conceptual argument for the claim that conditional probability is prior to unconditional probability, while Section 1.3 considers a family of mathematical arguments for this claim, leading to consideration specifically of the question of how to understand probability conditional on events of probability 0. Section 1.4 discusses several mathematical principles that have been alleged to be important for understanding how probability 0 behaves, and raises a dilemma for probability conditional on events of probability 0. Section 2 and Section 3 take the two horns of this dilemma and describe the two main competing families of mathematical accounts of conditional probability for events of probability 0. Section 4 summarizes the results, and their significance for the two arguments that conditional probability is prior to unconditional probability. (shrink)

Many philosophers have become worried about the use of standard real numbers for the probability function that represents an agent's credences. They point out that real numbers can't capture the distinction between certain extremely unlikely events and genuinely impossible ones—they are both represented by credence 0, which violates a principle known as “regularity.” Following Skyrms 1980 and Lewis 1980, they recommend that we should instead use a much richer set of numbers, called the “hyperreals.” This essay argues that this popular (...) view is the result of two mistakes. The first mistake, which this essay calls the “numerical fallacy,” is to assume that a distinction that isn't represented by different numbers isn't represented at all in a mathematical representation. In this case, the essay claims that although the real numbers do not make all relevant distinctions, the full mathematical structure of a probability function does. The second mistake is that the hyperreals make too many distinctions. They have a much more complex structure than credences in ordinary propositions can have, so they make distinctions that don't exist among credences. While they might be useful for generating certain mathematical models, they will not appear in a faithful mathematical representation of credences of ordinary propositions. (shrink)

Since its first appearance in 1821/22, The Christian Faith has had a fractious history of reception. It implements decisive departures for theology, founding the possibility to speak about God on human freedom. It recognises the role of historical consciousness, and the need to relate to advances in the natural sciences. The study investigates the early critiques of Schleiermacher’s analysis of the feeling of utter dependence, of his conception of Christ as the archetype of the God-consciousness, and of his doctrine of (...) God in terms of absolute causality. It reconstructs the revisions carried out in the second edition of 1830/31 as a break-through to a transcendental argumentation. Does Schleiermacher’s elaboration of the anthropological turn in theology leave it defenseless against the dissolution of faith in a saving God in Feuerbach’s projection thesis? Does it offer a naturalising account of religion? And where does the interconnectedness of nature established by God leave what was prized by the Romantics, human individuality? Ongoing objections and new constellations of questions are examined in their relevance for a modern theology that spells out faith in God as a practical self-understanding. “Maureen Junker-Kenny’s book is an outstanding presentation of Schleiermacher’s theology. She attends not only to the development of his method from the first to the second edition of The Christian Faith, but also to his concrete interpretation of Creation, Christology, Redemption, Theological Anthropology, especially human freedom, and his understanding of God. The book has an exceptional value in the way she relates Schleiermacher not only to his contemporaries, but also contemporary concerns. Schleiermacher’s theology is shown in its relation to the modernity of his age, but also the ongoing modernity of today. The book has a depth and breath that make it indispensable not only for historical theology, but also contemporary constructive theology.” – Francis Schüssler Fiorenza, Harvard Divinity School “In Self, Christ and God in Schleiermacher’s Dogmatics. A Theology Reconceived for Modernity, Maureen Junker-Kenny proves herself to be not only a distinguished interpreter of Schleiermacher’s work, but a creative practitioner in her own right of his dialogical method. Elegantly conceived and beautifully written, the book shows how Schleiermacher connected the different aspects of his thought—form/content, structure/doctrine, piety/critical rigor—into a coherent system. Self, Christ and God in Schleiermacher’s Dogmatics is now the only guide to Schleiermacher’s magnum opus, Christian Faith, anyone needs.” – Christine Helmer, Northwestern University, Chicago.

The first four essays in this guide are devoted to the study of Wittgenstein′s own ideas about philosophy. The remaining six apply his ideas to the work of other thinkers.

Expected accuracy arguments have been used by several authors (Leitgeb and Pettigrew, and Greaves and Wallace) to support the diachronic principle of conditionalization, in updates where there are only finitely many possible propositions to learn. I show that these arguments can be extended to infinite cases, giving an argument not just for conditionalization but also for principles known as ‘conglomerability’ and ‘reflection’. This shows that the expected accuracy approach is stronger than has been realized. I also argue that we should (...) be careful to distinguish diachronic update principles from related synchronic principles for conditional probability. (shrink)

What is mind? This book attempts to give a philosophical answer to that question in language accessible to the layperson, but with a rigor acceptable to the specialist. Published on the centenary of the birth of Wittgenstein and the 40th anniversary of the publication of Gilbert Ryle 's classic The Concept of Mind, this work testifies to the influence of those thinkers on Kenny's own work in the philosophy of mind, and assembles Kenny's ideas on philosophical psychology into (...) a systematic whole.

Smith gives an excellent overview on research in language evolution, in which he discusses several recent models of how linguistic systems and the cognitive capacities involved in language learning may have co‐evolved. He illustrates how combined pressures on language learning and communication/use produce compositionally structured languages. Once in place, a (culturally transmitted) communication system creates new selection pressures on the capacity for acquiring these systems.

Proponents of the this-universe objection to fine-tuning arguments for a multiverse claim that while the multiverse hypothesis raises the probability that some universe is fine-tuned for life, it fails to raise the probability that this one is. Because that is so, they further argue, those who take the fine-tuning of this universe as evidence for a multiverse are guilty of a probabilistic fallacy. Some opponents of the this-universe objection contend that it turns on contentious assumptions regarding the essential properties of (...) universes and agents. In particular, it is alleged to turn on the assumption that universes fail to have their nomic properties essentially as well as on the assumption that we could not have existed in other universes. I argue by contrast that the this-universe objection does not depend on these assumptions. (shrink)

In three respects, ethics can be marked by the category of the ‘priceless’. Its key reference point, ‘human dignity’, was described by Kant as the exact opposite to what can be priced in equivalents. As an enterprise, ethics is ‘priceless’ as a commitment of the human spirit which goes beyond and against the attitude of success calculation. Yet, an understanding of ethics as unconditional recognition and the anticipatory, asymmetric, innovative praxis (Helmut Peukert) that expresses it have a cost. Where does (...) the motivation to forego, for example, ethically problematic therapies, originate? How can respect for what is priceless be sustained in the face of the relentless spread of market categories diagnosed, among others, by Jürgen Habermas and Paul Ricoeur, against which religions may raise a delaying veto? Only a Christology that can adequately conceptualise the experience of the graciousness and superabundance of God’s gift is able to support the increasingly counter-cultural conviction of something beyond our disposition.

Whistleblowers are a vital means of protecting society because they provide information about serious wrongdoing. And yet, people who speak up can suffer. Even so, debates on whistleblowing focus on compelling employees to come forward, often overlooking the risk involved. Theoretical understanding of whistleblowers’ post-disclosure experience is weak because tangible and material impacts are poorly understood due partly to a lack of empirical detail on the financial costs of speaking out. To address this, we present findings from a novel empirical (...) study surveying whistleblowers. We demonstrate how whistleblowers who leave their role as a result of speaking out can lose both the financial and temporal resources necessary to redevelop their livelihoods post-disclosure. We also show how associated costs involving significant legal and health expenditure can rise. Based on these insights, our first contribution is to present a new conceptual framing of post-disclosure experiences, drawing on feminist theory, that emphasizes the bodily vulnerability of whistleblowers and their families. Our second contribution repositions whistleblowing as a form of labour defending against precarity, which involves new expenses, takes significant time, and often must be carried out with depleted income. Bringing forth the intersubjective aspect of the whistleblowing experience, our study shows how both the post-disclosure survival of whistleblowers, and their capacity to speak, depend on institutional supports or, in their absence, on personal networks. By reconceptualizing post-disclosure experiences in this way—as material, embodied and intersubjective—practical implications for whistleblower advocacy and policy emerge, alongside contributions to theoretical debates. Reversing typical formulations in business ethics, we turn extant debates on the ethical duty of employees to speak up against wrongdoing on their heads. We argue instead for a responsibility to protect whistleblowers exposed to vulnerability, a duty owed by those upon whose behalf they speak. (shrink)

Throughout his long and distinguished career, Sir Anthony Kenny has encountered some of the most notable and influential leaders of the post-war world. In these brilliantly vivid vignettes Kenny offers telling and often unexpected insights into the achievements, flaws and foibles of sixty public figures—past and present—each of whom has contributed in decisive ways to British political, spiritual, and cultural heritage.

It is sometimes alleged that arguments that probability functions should be countably additive show too much, and that they motivate uncountable additivity as well. I show this is false by giving two naturally motivated arguments for countable additivity that do not motivate uncountable additivity.

Sir Anthony Kenny presents a second edition of his landmark work The Aristotelian Ethics, which transformed Aristotle studies in 1978 by showing, on stylistic, historical, and philosophical grounds, that the Eudemian Ethics was a mature work with as strong a claim to be Aristotle's ethical masterpiece as the more widely studied Nicomachean Ethics. In this new edition Kenny offers a critical survey of developments in the field since The Aristotelian Ethics was first published. Kenny also addresses the (...) criticisms of his first edition, both accepting those he sees as justified and addressing and refuting those which he feels are unfounded. The book remains essential reading for anyone interested in Aristotle's ethical works, arguably the most influential ever written. (shrink)

Covers the philosophical concept of the self. Kenny concentrates here on two of the roots of ""self"" - the epistemological root and the psychological root. It is the purpose of this lecture to claim that the self of the philosophers is a mythical entity, and so likewise is the self of the poets and dramatists to the extent to which it is modelled on the philosophers' myth.

Many philosophers have argued that "degree of belief" or "credence" is a more fundamental state grounding belief. Many other philosophers have been skeptical about the notion of "degree of belief", and take belief to be the only meaningful notion in the vicinity. This paper shows that one can take belief to be fundamental, and ground a notion of "degree of belief" in the patterns of belief, assuming that an agent has a collection of beliefs that isn't dominated by some other (...) collection in terms of the overall balance of truth and falsity that it could contain.

Procédant à une analyse comparative du traitement qu’Aristote réserve à la philia dans les livres VIII et IX de l’ Éthique à Nicomaque et dans le livre VII de l’ Éthique à Eudème, je soutiens dans cet article qu’à bien des égards, l’approche « eudémienne » se révèle plus claire et cohérente. Plusieurs sujets sur lesquels les deux Éthiques offrent des traitements différents sont successivement examinés (par exemple, la méthode endoxique, la théorie du « focal meaning », la question de (...) l’amour de soi, celle de l’auto-suffisance). Je suggère pour finir que la façon la plus simple de rendre compte de ces différences est de faire l’hypothèse que le traitement de l’amitié dans l’ Éthique à Nicomaque précède celui de l’ Éthique à Eudème.

Mental or computer simulation of cause and effect of certain behaviors is a recognized approach to changing one’s attitude or triggering an action. Meanwhile, psychology research results suggest that frequency of simulation may affect the corresponding persuasiveness. This paper argues that with always-on sensing and data-driven visualization technologies, interactive tangible systems can be designed to simulate hypothetical outcomes of real-life behaviors in everyday contexts, which repeatedly stimulate users’ imagination of behavioral consequences and thereby behavioral intentions. To investigate the effect, a (...) working prototype of Incingarette, including a smart ashtray in connection with a digital picture frame, was built. When the ashtray is used for smoking, the digital picture is incrementally covered by virtual dust. Field trials involved participants in five daily smoking sessions. Post-session surveys show increasingly stronger perceived causality between smoking and the simulated outcomes, increasingly more vivid mental imagery of consequences, and increasingly intense intention to reduce smoking. Results suggest that repeatedly presenting simulated outcomes cognitively linked to real-life behaviors can increase behavioral intentions. (shrink)

Bayesians standardly claim that there is rational pressure for agents’ credences to cohere across time because they face bad (epistemic or practical) consequences if they fail to diachronically cohere. But as David Christensen has pointed out, groups of individual agents also face bad consequences if they fail to interpersonally cohere, and there is no general rational pressure for one agent's credences to cohere with another’s. So it seems that standard Bayesian arguments may prove too much. Here, we agree with Christensen (...) that there is no general rational pressure to diachronically cohere, but we argue that there are particular cases in which there is rational pressure to diachronically cohere, as well as particular cases in which interpersonal probabilistic coherence is rationally required. More generally, we suggest that Bayesian arguments for coherence apply whenever a collection (of agents or time slices) has a shared dimension of value and an ability to coordinate their actions in a range of cases relevant to that value. Typically, this shared value and ability to coordinate is very strong across the time slices of one human being, and very weak across different human beings, but there are special cases where these can switch—i.e., some groups of humans will have as much reason for their beliefs to cohere across a particular range of cases as the time slices of one human usually do, but some time slices of a human will have as much freedom to differ in their beliefs from the others as the members of a group usually do.
