Bayesian learning theory and evolutionary theory both formalize adaptive competition dynamics in possibly high‐dimensional, varying, and noisy environments. What do they have in common and how do they differ? In this paper, we discuss structural and dynamical analogies and their limits, both at a computational and an algorithmic‐mechanical level. We point out mathematical equivalences between their basic dynamical equations, generalizing the isomorphism between Bayesian update and replicator dynamics. We discuss how these mechanisms provide analogous answers to the challenge of adapting (...) to stochastically changing environments at multiple timescales. We elucidate an algorithmic equivalence between a sampling approximation, particle filters, and the Wright‐Fisher model of population genetics. These equivalences suggest that the frequency distribution of types in replicator populations optimally encodes regularities of a stochastic environment to predict future environments, without invoking the known mechanisms of multilevel selection and evolvability. A unified view of the theories of learning and evolution comes in sight. (shrink)

Disagreements about the morality of markets, and about self-interested behavior within markets, run deep. They arise from perspectives within economics and political philosophy that appear to have nothing in common. In this book, Daniel Finn provides a framework for understanding these conflicting points of view. Recounting the arguments for and against markets and self-interest, he argues that every economy must address four fundamental problems: allocation, distribution, scale, and the quality of relations. In addition, every perspective on the morality of markets (...) addresses explicitly or implicitly the economic, political, and cultural contexts of markets, or what Finn terms 'the moral ecology of markets'. His book enables a dialogue among the various participants in the debate over justice in markets. In this process, Finn engages with major figures in political philosophy, including John Rawls, Robert Nozick, and Michael Walzer, as well as in economics, notably Milton Friedman, Friedrich Hayek, and James Buchannan.

In a pair of influential papers, Tamar Schapiro argues that childhood is a ‘predicament’, in that children lack stable characters that allow them to be subjects of ascriptions of moral responsibility. Comparing childhood to the political ‘state of nature’, Schapiro holds that childhood is a stage of life from which agents must be liberated. I argue that the comparison to the state of nature gives rise to the implication that ‘instantaneous adulthood’ would be a desirable state. Canvassing the nascent literature (...) on ‘intrinsic goods of childhood’, I hold that such views cannot defeat Schapiro's implications, as they are based on theories of value that beg the question against Schapiro's. Only if childhood can be shown to be a necessary stage toward a normatively attractive adulthood can the ‘instantaneous adulthood’ implication be defeated. I show that Schapiro's view is only plausible if it incorporates the endorsement condition and the articulacy condition. But these are incompatible with instantaneous adulthood. Childhood can be seen as the stage in life in which agents actively endorse their characters, and gain articulacy with respect to the maxims that constitute them. (shrink)

The process of constructing a social reality where “difference” becomes a social asset rather than a monster that threatens peace and progress must commence with a phenomenological understanding of social interactions within and among human societies. In my opinion, Hegel, more than any other thinker, has constructed a phenomenological framework that adequately captures and represents the nature of group interactions within human societies. This paper explores the Hegelian phenomenon of social identity, and, especially, characterizes the interactions between and among various (...) social identities. It is a modest effort to contribute theoretically to the available discourse on the management of “difference” in multi-ethnic societies. (shrink)

In this dissertation I advance a Jaspersian account of the formation and possession of irrational attitudes. This account stands in opposition to two competing views – externalism and internalism with respect to rational and irrational attitudes. According to externalism, a subject’s attitudes are irrational when they fail to satisfy standards or criteria independent of the subject, such as laws of logic, methods for evidence acquisition, and rules of decision theory. According to internalism, a subject’s attitudes are irrational when they are (...) not supported by reasons selected by the subject. In this dissertation, I take Donald Davidson’s theory of rational and irrational attitudes to be a case of externalism and John Searle’s theory of rational and irrational attitudes to be a case of internalism. While articulating and identifying the merits of externalism and internalism with respect to rational or irrational attitudes, I argue that each account ends up in difficulties: Davidson’s externalism cannot account for the experience of freedom, an individual’s subjectivity, and is unable to avoid an infinite regress of rules; Searle’s internalism struggles to avoid solipsism and an infinite regress of reasons. Karl Jaspers’ account of rational and irrational attitude formation, I argue, avoids the pitfalls of Davidson’s and Searle’s views while preserving the merits of each. On Jaspers’ account, a subject possesses rational attitudes insofar as that subject holds those attitudes to be always open to revision while, at the same time, using those attitudes to bring unity to all manner of phenomena and other attitudes. Irrationality, by contrast, occurs, on the Jaspersian view, when a subject holds onto attitudes with complete and absolute resolution and interprets all else according to these attitudes. Having defined a Jaspersian account of rational and irrational attitudes, I show how it accounts for the irrationality of delusional beliefs and the irrationality of certain worldviews. On Jaspers’ view, I argue, delusions and worldviews are irrational insofar as they are held with absolute conviction, are unamenable to modification, and are used to understand all available evidence, views, and opinions.

My dissertation is a systematic defense of the moral relevance of alternative possibilities. As such, it constitutes an attack on semi-compatibilism. ;To begin, then, I defend alternative possibilities against three related but independent lines of criticism. The most prominent of these is Harry Frankfurt's now famous counterexample strategy in which cases are constructed that purport to show that a person can, in fact, be responsible even when he cannot do otherwise. Another line of criticism is John Fischer's "flicker of freedom" (...) argument, which builds on Frankfurt-type argumentation by challenging the "robustness" of alternative possibilities. Finally, some recent critics of alternative possibilities have developed "reasons-responsiveness" accounts of moral responsibility that seem further to invalidate the importance of the power to do otherwise. By extending traditional concerns and developing new objections, I argue that room remains for the possible relevance of an alternative possibilities condition on moral responsibility. ;I try to make a positive case for the plausibility of relevance by offering reasons to think that the ability to do otherwise plays an important role in our moral life. Alternatives are important, I argue, because giving up a "freedom to do otherwise" condition would put us in an epistemic bind with respect to our responsibility. That is, the kind of confidence we ordinarily have in our own moral responsibility would be unjustified if it turned out that we do not have alternatives. A second consideration in favor of the relevance of alternatives is distinctively moral. I explore and exploit the relationship between the ability to do otherwise and the putatively Kantian idea that "ought" implies "can," concluding that the semi-compatibilist must either reject both alternative possibilities and the Kantian thesis, or accept that people would not be blameworthy for their moral failures under determinism. Neither option is attractive. ;I conclude, then, that there is good reason to believe that alternative possibilities are necessary for moral responsibility and that semi-compatibilism should be rejected. Our intuitions about the importance of being able to do otherwise can still factor into the traditional arguments to the conclusion that moral responsibility is incompatible with causal determinism.

Much of contemporary philosophy of mind is dominated by the intersection of three topics: physicalism, the conceivability argument, and the necessary a posteriori. I will be concerned here to describe the consensus view of these topics; to explain why I think this account is mistaken; and to briefly sketch an alternative.

A pergunta pelo sentido do ser será aqui orientada para a afirmação do postulado de uma condição essencialmente precária do mortal, a partir da qual ele deverá ser radicalmente situado em seu horizonte histórico-metafísico fundamentalmente através do seu comprometimento existencial com uma abertura abissal do fenômeno de mundo que excede sua capacidade de apreensão.

We propose the use of variable declarations in natural deduction. A variable declaration is a line in a derivation that introduces a new variable into the derivation. Semantically, it can be regarded as declaring that the variable denotes an element of the universe of discourse. Undeclared variables, in contrast, do not denote anything, and may not occur free in any formula in the derivation. Although most natural deduction systems in use today do not have variable declarations, the idea can be (...) traced back to one of the first papers on natural deduction. We show how the use of variable declarations in natural deduction leads to a formal system that has a number of desirable features: It is simple, easy to use and understand, and corresponds closely to ordinary informal reasoning. Soundness and completeness of the system are easily proven. Furthermore, the system clarifies the role of the existential instantiation rule in natural deduction. (shrink)

Pour certains philosophes pluralistes politiques, accepter la thèse de pluralisme des valeurs entraîne le rejet de l’autonomie libérale en faveur d’une forme de libéralisme fondée sur l’idéal de la tolérance. Cette idée est fausse. D’abord le pluralisme des valeurs partage avec le relativisme la difficulté inhérente à toute tentative de tirer une conclusion normative d’une thèse descriptive. Chercher à soutenir l’argument en comblant les prémisses manquantes montre que le pluralisme des valeurs est plus naturellement lié au libéralisme autonomiste qu’à un (...) libéralisme fondé sur la tolérance. C’est parce que les individus doivent posséder une capacité de choix autonome pour que le pluralisme puisse les concerner. (shrink)

Les philosophes et les clowns se ressembleraient-ils? L'hypothèse est peut-être moins incongrue qu'il n'y paraît. Elle est même suggérée par... des philosophes, en particulier ceux qui, observant ce que devient l'individu humain depuis le début du terrible XXe siècle, interrogent sa foncière ambivalence. Le clown serait-il le modèle d'un sujet devenu bancal mais rusé, dépassé mais calculateur, égaré mais lucide, épuisé mais inventeur d'espérances? Le temps des clowns que décrivent les philosophes et écrivains ici invités (Ernst Bloch, Siegfried Kracauer, Walter (...) Benjamin, Franz Kafka, Theodor Adorno, Samuel Beckett, Hannah Arendt, Günther Anders) n'est pas celui des Lumières, et il n'est pas non plus celui des transports romantiques ou tragiques du XIXe. Il témoigne d'une expérience historique spécifique, qui pourrait bien être encore, pour une grande part, la nôtre."--Page 4 of cover. (shrink)

In this paper I provide an account of physical symmetries, which are defined relative to a specific physical theory, and overarching symmetries, which hold across many different physical theories. I outline two general strategies for uniting disparate physical symmetries under the same overarching symmetry, calling the first "realist" and the second "conventionalist". Finally, I argue that, should physicists and philosophers be interested in finding symmetries that do interesting and helpful physical and metaphysical work, the realist strategy would serve them better (...) than the conventionalist strategy.

This philosophical meditation, which deals with death as question, presence, and even teacher, begins with Ramchandra Gandhi’s penetrating essay ‘On Meriting Death.’ What does it mean ‘to merit’ death? To provide an answer, I travel through RCG’s corpus, in dialog with contemporary theorists such as Sri Aurobindo, Daya Krishna, and Mukund Lath. RCG implies that the question about ‘meriting’ death, and life, is not and cannot be ‘personal’ or ‘isolated’. For X to die, is for his close and distant samāj (...) a matter of losing him and living without him. Hence meriting death, as also life, is a joint venture which involves deep understanding regarding non-isolation as the heart of the human situation. RCG’s creative thinking, or svarāj in ideas, reaches its peak when he dares to offer an answer of his own to the piercing question kim āścaryam, ‘what is amazing?’ raised in the Yakṣa-praśna episode of the Mahābhārata. For RCG, the heart of the matter is not the ‘ungraspability’ of one’s unavoidable death, or the perennial search for ‘permanence’ in vain, but our failure to perceive ‘that in the martyā which is amṛta,’ i.e., a sense of solidarity in the face of death, connecting ‘I and Thou,’ which he derives from the icchā mṛtyu of his grandfather, the famous Mahatma.

ABSTRACTIn this commentary I suggest that a comparative investigation of Ancient psychological notions may contribute to Professor Lloyd's project of understanding the role that analogy plays in human reasoning. In particular, I propose that the Greek notion of imagination may serve as a starting point. I argue that, because in Platonic and Aristotelian thought the ultimate object of knowledge is form, thinkers working in this paradigm were obliged to introduce a faculty mediating between the senses and the intellect. This is (...) the imagination. Some of the problems associated with Greek conceptions of imagination carry over to the use of analogy. I suggest that because Chinese thought had a very different approach to images and a different approach to the object of knowledge, they did not need to forge a conception of a specific faculty of imagination and were thus in a position to exploit analogies in a way which was rather different from Greeks.

Moral contracts and the patient-physician relationship.

Kant's relation to religion and theology is complex since he tries both to delimit theology's influence and to inherit its discursive power. The essay explores the different critical strategies and rhetorical means that Kant uses to deal with theology: theological analogies and metaphors in his systematic thought, a new kind of,philosophy of religion,' a political theology of civil society, and finally a specific way of reading the Bible.

Current medical and legal literature generally favors a definition of death based on total cessation of brain functioning. It does not, however, supply the reasoning for this recommendation. None of the arguments for whole-brain death is convincing; there exists, however, a satisfactory rationale for identifying death with cortical death. Policymakers should refrain from endorsing any of these arguments, focussing instead on the pragmatic tasks involved in guiding medical care at the end of life.

Theological study and teaching at Oxford prior to the First World War have been characterized as unambitious and lacking in critical rigour. In contrast to the constructive theological endeavours of biblical scholars at Cambridge or the bold revisionism of F.D. Maurice at King's College London, Oxford's theological teaching and research are perceived through the lens of E.B. Pusey and his High Church colleagues. Prior to the First World War, however, circumstances and personalities coincided to produce a radical set of proposals (...) from the Board of the Faculty of Theology under the leadership of Henry Scott Holland, Regius Professor of Divinity from 1910 until his death in 1918. Had Oxford's graduate legislative assembly, Convocation, not comprehensively rejected the reforms approved by the resident MAs, Oxford's Faculty might have been transformed into an influential centre of comparative religion. In this article, the prevailing accounts of Oxonian ‘narrowness’ are challenged through an account of this seminal moment in the history of the Faculty. Using correspondence from the Bodleian Library Special Collections, minutes and reports from the Oxford University Archives, pamphlet material and national, ecclesiastical, and University journals, the article seeks to identify the reasoning behind the proposed reforms and the significance of that reasoning for the history of modern theology in England. In so doing, it is suggested that the standard characterization of theological life at Oxford in the ‘long nineteenth century’ merits revision and further clarification. (shrink)
