Lewis signaling games illustrate how language might evolve from random behavior. The probability of evolving an optimal signaling language is, in part, a function of what learning strategy the agents use. Here we investigate three learning strategies, each of which allows agents to forget old experience. In each case, we find that forgetting increases the probability of evolving an optimal language. It does this by making it less likely that past partial success will continue to reinforce suboptimal practice. The learning (...) strategies considered here show how forgetting past experience can promote learning in the context of games with suboptimal equilibria. (shrink)

We consider the efficacy of various forms of reinforcement learning with punishment in evolving linguistic conventions in the context of Lewis-Skyrms signalling games. We show that the learning strategy of reinforcement with iterative punishment is highly effective at evolving optimal conventions in even complex signalling games. It is also robust and can be easily extended to a self-tuning variety of reinforcement learning. We briefly discuss some of the virtues of reinforcement with iterative punishment and how it may be related to (...) learning in nature. (shrink)

It is argued that taken together, two widely held claims ((i) sentences express structured propositions whose structures are functions of the structures of sentences expressing them; and (ii) sentences have underlying structures that are the input to semantic interpretation) suggest a simple, plausible theory of propositional structure. According to this theory, the structures of propositions are the same as the structures of the syntactic inputs to semantics they are expressed by. The theory is defended against a variety of objections.

Theologians and philosophers of religion are increasingly interested in physics. From the fine-tuning of universal constants to quantum mechanics, relativity, and cosmology, physics is a surprisingly common subject where religion is involved. Bridging the gap between issues in religion and those in physics can be quite difficult, however. Fortunately, the philosophy of science provides a middle ground between the two disciplines. In this book, a philosopher of science provides a critical analysis of the ways in which physics is brought into (...) play in matters of religion. (shrink)

It is often claimed (1) that levels of nature are related by supervenience, and (2) that processes occurring at particular levels of nature should be studied using dynamical systems theory. However, there has been little consideration of how these claims are related. To address the issue, I show how supervenience relations give rise to ‘supervenience functions’, and use these functions to show how dynamical systems at different levels are related to one another. I then use this analysis to describe a (...) graded approach to non-reductive physicalism, and to critically assess Davidson’s arguments for psychological anomaly. I also show how this approach can inform empirical research in cognitive science. (shrink)

ABSTRACT An intellectually charitable understanding of populism might begin by recognizing that, since populist citizens tend to be politically uninformed and lacking in higher education, populist ideas are likely to be inarticulate reproductions of the tacit assumptions undergirding non-populist or “mainstream” culture rather than stemming from explicit theoretical constructs, such as an apotheosis of the unity or the will of “the people.” What features of our ambient culture, then, could explain the simplistic and combative approach that populists seem to take (...) to politics and policy, their impatience with political debate and deliberation, their willingness to set aside democratic legal forms and political norms, their nationalism, their personalization of politics, their inclination toward conspiracy theorizing, their fondness for fringe sources of information, and their suspicion of political, scientific, and media elites? Using focus group and survey data, we can understand these populist traits as reflections of the culture of “democratic technocracy”: a regime in which we, the people, are assumed capable of rendering sound judgments about how to solve our social and economic problems. Whether or not this assumption is warranted, its cultural dominance seems likely to generate the ideas that populist citizens apparently take for granted. (shrink)

Justice requires giving people what they deserve. Or so many philosophers – and according to many of those philosophers, everyone else – thought for centuries. In the 1970’s and 1980’s, however, perhaps under the influence of Rawls’s (1971) desert-less theory, desert was largely cast out of discussions of distributive justice. Now it is making a comeback. In this chapter I consider recent research on the concept of desert, arguments for its requital, and connections between desert and other distributive ideals. I (...) suggest that desert-sensitive theories of distributive justice, though they face obstacles, have a promising future. (shrink)

The Allegiance of Thomas Hobbes offers a new interpretation of Thomas Hobbes's response to the English Revolution. By focusing on his religious thought, it debunks the standard view of him as a royalist, and recovers his sympathies with the religious projects of the 1640s and 1650s. This reinterpretation culminates with an exploration of Hobbes's surprising sympathies with Oliver Cromwell and his supporters. By placing Thomas Hobbes within fresh contexts, Professor Collins offers a new angle of vision on the religious significance (...) of the English Revolution itself. (shrink)

The steady stream of books on medieval manuscripts addressed to a popular audience over the past two decades coincides with the advent of tablets such as Amazon's Kindle. As the flatlands of the digital realm encompass more of life, nostalgia for a tactile realm of reading, whether in the making or the perception of artifacts, asserts itself, as does the desire to immerse oneself in the real space of the conventional book, as opposed to the virtual yet denatured spaces of (...) the metaverse. No accident, then, that, following an introduction that gestures toward medieval subjects and to readers other than Christian, Wellesley's engaging, if episodic, account of medieval manuscripts (published in the United States by Basic Books as The Gilded Page: The Secret Lives of Medieval Manuscripts) opens with a prologue in which she recounts her hands-on visit to a parchment maker, during which she tried to slough the hair off a hide using an implement known as a scudder.Manuscripts permit one to come into contact with the past, or at least to harbor the illusion that one can. Wellesley's book repeatedly evokes the contingency of landmarks and masterworks that make up the history of culture. Pendant chapters treat “Discoveries,” medieval as well as modern, of books that, when first encountered, had been lost to view for the better part of a millennium, as well as the “Near-Disasters” by which famous works such as Beowulf (or indeed entire libraries) made it down to modernity by only a hair's breadth—despite the devil's assurance in Bulgakov's The Master and Margarita that “manuscripts don't burn.” Within a binding held tight by clasps, parchment—even when exposed to fire—can survive, if it is not then reduced to a mess by the water used to douse the flames. Having been rescued from the ruins of Ashburnham House, which burned in 1731, the detached pages of the Cotton Genesis at the British Library—one of a handful of illustrated biblical manuscripts from late antiquity—now look like soggy, burned toast pressed between glass sheets to conserve what little is left.Other chapters in this book make things personal, matching brief biographies of celebrated manuscripts with famous (or not so famous) persons, whether patrons, scribes, or artists—a sequence that reflects their order of importance in the Middle Ages. To have included an afterword as well as an epilogue seems indulgent: one, too brief, on the impact of printing (focused on the English printer Caxton), the other on “The Use and Misuse of the Past,” which dwells on the dispersal of monastic libraries after the English Reformation. The focus on the British Isles, to the neglect of the continent, risks being too narrow for a book so general in scope. The book's very British flavor, however, is also part of what lends it a familiar, chatty tone. A pleasant, companionable read, this extended essay does not advance our knowledge of medieval manuscripts, but it does help diffuse it to a larger audience in a way that makes old books seem companionable. Rather than Hidden Hands, the book might well have been called Comites latentes: hidden friends. (shrink)

This paper concerns two composite Lewis-Skyrms signaling games. Each consists in a base game that evolves a language descriptive of nature and a metagame that coevolves a language descriptive of the base game and its evolving language. The first composite game shows how a pragmatic notion of truth might coevolve with a simple descriptive language. The second shows how a pragmatic notion of probability might similarly coevolve. Each of these pragmatic notions is characterized by the particular game and role that (...) it comes to play in the game. (shrink)

Husserl is well known for his critique of the “mathematizing tendencies” of modern science, and is particularly emphatic that mathematics and phenomenology are distinct and in some sense incompatible. But Husserl himself uses mathematical methods in phenomenology. In the first half of the paper I give a detailed analysis of this tension, showing how those Husserlian doctrines which seem to speak against application of mathematics to phenomenology do not in fact do so. In the second half of the paper I (...) focus on a particular example of Husserl’s “mathematized phenomenology”: his use of concepts from what is today called dynamical systems theory. (shrink)

Scientists’ identities and social locations influence their work, but the content of scientific work can also influence scientists. Theory from feminist science studies, autoethnographic accounts, interviews, and experiments indicate that the substance of scientific research can have profound effects on how scientists are treated by colleagues and their sense of belonging in science. I bring together these disparate literatures under the framework of professional cultures. Drawing on the Survey of Earned Doctorates and the Web of Science, I use computational social (...) science tools to argue that the way scientists write about sex in their research influences the future gender ratio of PhDs awarded across 53 subfields of the life sciences over a span of 47 years. Specifically, I show that a critical paradigm of “feminist biology” that seeks to de-essentialize sex and gender corresponds to increases in women’s graduation rates, whereas “sex difference” research—sometimes called “neurosexism” because of its emphasis on essential, categorical differences—corresponds to decreases in women’s graduation rates in most fields.

This forward-thinking collection presents new work that looks beyond the division between the analytic and continental philosophical traditions—one that has long caused dissension, mutual distrust, and institutional barriers to the development of common concerns and problems. Rather than rehearsing the causes of the divide, contributors draw upon the problems, methods, and results of both traditions to show what post-divide philosophical work looks like in practice. Ranging from metaphysics and philosophy of mind to political philosophy and ethics, the papers gathered here (...) bring into mutual dialogue a wide range of recent and contemporary thinkers, and confront leading problems common to both traditions, including methodology, ontology, meaning, truth, values, and personhood. Collectively, these essays show that it is already possible to foresee a future for philosophical thought and practice no longer determined neither as "analytic" nor as "continental," but, instead, as a pluralistic synthesis of what is best in both traditions. The new work assembled here shows how the problems, projects, and ambitions of twentieth-century philosophy are already being taken up and productively transformed to produce new insights, questions, and methods for philosophy today.

Recent developments, both in the cognitive sciences and in world events, bring special emphasis to the study of morality. The cognitive sciences, spanning neurology, psychology, and computational intelligence, offer substantial ad- vances in understanding the origins and purposes of morality. Meanwhile, world events urge the timely synthesis of these insights with traditional ac- counts that can be easily assimilated and practically employed to augment moral judgment, both to solve current problems and to direct future action. The object of the following (...) paper is to present such a synthesis in the form of a model of moral cognition, the ACTWith model of conscience. The purpose of the model is twofold. One, the ACTWith model is intended to shed light on personal moral dispositions, and to provide a tool for actual human moral agents in the refinement of their moral lives. As such, it relies on the power of personal introspection, bolstered by the careful study of moral exemplars available to all persons in all cultures in the form of literary or religious fig- ures, if not in the form of contemporary peers and especially leadership. Two, the ACTWith model is intended as a minimum architecture for fully func- tional artificial morality. As such, it is essentially amodal, implementation non-specific and is developed in the form of an information processing control system. There are given as few hard points in this system as necessary for moral function, and these are themselves taken from review of actual human cognitive processes, thereby intentionally capturing as closely as possible what is expected of moral action and reaction by human beings. Only in satisfying these untutored intuitions should an artificial agent ever be properly regarded as moral, at least in the general population of existing moral agents. Thus, the ACTWith model is intended as a guide both for individual moral develop- ment and for the development of artificial moral agents as future technology permits. (shrink)

The first claim in the target article was that there is as yet no transparent, causal account of the relations between consciousness and brain-and-behaviour. That claim remains firm. The second claim was that the contents of consciousness consist, psychologically, of the outputs of a comparator system; the third consisted of a description of the brain mechanisms proposed to instantiate the comparator. In order to defend these claims against criticism, it has been necessary to clarify the distinction between consciousness-as-such and the (...) contents of consciousness, to widen the description of the neural machinery instantiating the comparator system, and to clarify the relationship between the contents of consciousness in the here-and-now and episodic memory.

This article examines not only how events are verbally reported in everyday and institutional storytelling episodes, but also how the actions witnessed are enacted by participants. This is particularly important to not only the believability of what occurred and is being discussed, but also how ordinary audience members react to stories and how they believe the truthfulness of them. As is seen in data analyzed from multiple sources, the way in which something is both reported and enacted has major implications (...) for not only the telling of stories, but what we know about the world around us. Questions about the idea of ‘direct reported actions’ are also considered. (shrink)

Imaginary worlds are not a consequence of humans' exploratory tendencies as argued in the target article but a recent spinoff of a strong human tendency to create imaginary realities, that is, versions of how the world works that are fabricated (although we believe they are real) in order to allow us to believe we understand it and can control it.

The role of mechanistic evidence tends to be under-appreciated in current evidencebased medicine (EBM), which focusses on clinical studies, tending to restrict attention to randomized controlled studies (RCTs) when they are available. The EBM+ programme seeks to redress this imbalance, by suggesting methods for evaluating mechanistic studies alongside clinical studies. Drug approval is a problematic case for the view that mechanistic evidence should be taken into account, because RCTs are almost always available. Nevertheless, we argue that mechanistic evidence is central (...) to all the key tasks in the drug approval process: in drug discovery and development; assessing pharmaceutical quality; devising dosage regimens; assessing efficacy, harms, external validity, and cost-effectiveness; evaluating adherence; and extending product licences. We recommend that, when preparing for meetings in which any aspect of drug approval is to be discussed, mechanistic evidence should be systematically analysed and presented to the committee members alongside analyses of clinical studies.

Collective memory is thought to be something “more” than a conglomeration of personal memories which compose it. Yet, each of us, each individual in every society, remembers from a personal point of view. And if there is memory beyond personal experience through which collective identities are configured, in what “place” might one legitimately situate it? In addressing this question, this article examines the political significance of the distinction between two levels of what are often lumped together under the term of (...) “collective memory”: memories that are retained through the direct experience of groups or associations of a limited size and those that are rarely the object of direct experience constituting the events marking the identities of mass societies.

Claude Welch, the distinguished historian of nineteenth‐century religious thought, once declared that Samuel Taylor Coleridge ‘may be seen as the real turning point into the theology of the nineteenth century’ and that he ‘was as important for British and American thought as were Schleiermacher and Hegel’.2 Still, Coleridge remains largely marginalized in the annals of church history and theology despite his unwavering prominence throughout much of the nineteenth century. Perhaps it should come as no surprise, then, that Coleridge's posthumously published (...) Confessions of an Inquiring Spirit , with its rejection of the verbal infallibility of Scripture and elevation of the importance of the individual in rightly discerning the truths of the Christian faith, has often been misread as an attestation of the primacy of the individual subject over the biblical text. It has been treated alternately as a document that signals the emergence of German higher criticism in England,3 a Romantic appeal to the fundamental importance of the subjective in religion,4 and an early form of reader‐oriented literary criticism.5 In this article I suggest that the attention devoted to Coleridge's denial of the verbal inspiration of Scripture, epitomized by the phrase that biblical inspiration is constituted by ‘whatever finds me’, has overshadowed his equally significant attention to the authority of church tradition in that same document. More specifically, rather than arguing for subjectivism in biblical interpretation, Coleridge equally emphasizes the objective sources of revelation expressed in Scripture and the church traditions handed over from the apostles. Rather than proposing a model of biblical inspiration that is wholly individualistic, Coleridge maintains a vision of Christianity that affirms the vitality of both the authority of the church and that of the believer. Thus, Coleridge's theological contribution to religious history is not that of an aberrant, absent‐minded poet, but rather that of a central participant engaged in an ongoing and pivotal debate in the history of England: the relationship between Scripture and church traditions.In order to draw out this important, though neglected, strand of thought in those ‘Letters on the Scriptures’, the name by which the Confessions is sometimes identified,6 I begin by briefly clarifying the nature of the idea of tradition both in relation to Coleridge and English theology in the nineteenth century. I then summarize the argument of the Confessions as a whole and turn more particularly to those sections of the Confessions that suggest the role Coleridge assigns to church tradition in relation to Scripture. Finally, after assessing the authority of the church in relationship to the divine Word, I turn to Coleridge's earlier works and his notes on the Works of William Chillingworth in order to demonstrate that his views on the respective authority of both the individual and the church were consistently held since near the time of his conversion to Trinitarian Christianity. I conclude that Coleridge's conception of the relationship between Scripture and church traditions calls for a reevaluation of his place in the history of religious thought in England. (shrink)

La présente étude se consacre à un examen du concept de la mémoire collective en s'interrogeant sur l'interprétation que Paul Ricœur propose de ce concept dans son ouvrage La mémoire, l'histoire, l'oubli. L'auteur présente une lecture critique de l'interprétation de la mémoire collective chez Ricœur là ou Ricœur tente de comprendre ce phénomène par analogie avec la mémoire personnelle et risque, selon cette lecture, d'occulter les dimensions de la mémoire collective qui échappent à un tel rapport analogique. L'auteur tente alors (...) de dépasser le cadre de cette analogie par une analyse des sources symboliques et métapersonnelles de la mémoire collective. This study examines the concept of collective memory through an investigation of Paul Ricœur's interpretation of this concept in his work, La mémoire, l'histoire, l'oubli. In presenting a critical reading of the analogy Ricoeur establishes between collective and personal memory, the author argues that this analogy risks excluding those dimensions of collective memory which cannot be comprehended through such an analogy. The attempt is then made to surmount this difficulty through an analysis of collective memory in relation to its symbolic and metapersonal sources. (shrink)

This chapter considers two types of fine‐tuning, those dealing with the initial conditions of the universe and those based on fixed parameters. Three approaches have been taken to argue that fine‐tuning does not need any special explanation. The first is an appeal to coincidence. The second is that the data are biased by our own observations. The third has to do with the nature of probability itself. The chapter assesses each of these objections in detail. Many naturalistic explanations have been (...) offered for fine‐tuning. The chapter considers the three most important ones. The first is that future discoveries might show that fine‐tuning was not improbable after all. The second is that other life‐permitting ranges for the fine‐tuned constants (FTCs) might exist, allowing for exotic forms of life unlike ours. The third is that we might live in a multiverse of many different universes all with different values of FTCs. (shrink)

Psychopathy is increasingly in the public eye. However, it is yet to be fully and effectively understood. Within the context of the DSM-IV, for example, it is best regarded as a complex family of disorders. The upside is that this family can be tightly related along common dimensions. Characteristic marks of psychopaths include a lack of guilt and remorse for paradigm case immoral actions, leading to the common conception of psychopathy rooted in affective dysfunctions. An adequate portrait of psychopathy is (...) much more complicated, however. Though some neural regions and corresponding functions are commonly indicated, they range across those responsible for action planning and learning, as well as emotional processes. Accordingly, a complete fine-grained map of all neural mechanisms responsible for psychopathy has not been realized, and even if it were, such a map would have limited utility outside of the context of surgical or chemical intervention. The utility of a neural-level understanding of psychopathy is further limited by the fact that it is only applicable in the clinical identification of individual subjects, and the neuro-chemical/biological correction of those subjects after they are positively identified as psychopaths. On the other hand, an information processing model of moral cognition provides for wider-ranging applications. The theoretical and practical implications for such a feasible working model of psychopathic personalities are assessed. Finally, this chapter raises the possibility of directed modification of social-environmental factors (including at the meta-organizational level) discouraging the development of psychopathic personalities in the first place, modifications which are also open to simulation and testing in terms of the same model of moral cognition.

This review article examines Richard Ekins’ attempt to defend the concept of legislative intention from influential criticism, and to demonstrate its indispensable and central role in statutory interpretation. He rejects accounts of legislative intention in terms of the aggregation of the intentions of individual legislators, and instead, draws on recent philosophical work on the nature of group agency to propose a unitary model, in which the relevant intention is that of the legislature itself, although it is supported by the ‘interlocking’ (...) of the intentions of all its members. The legislature has two relevant intentions: a secondary or standing intention to operate by way of agreed procedures to develop and enact particular proposals for legislation to enhance the welfare of the community; and primary intentions that consist of the content of those proposals once the legislature has enacted them. Ekins restricts the evidence that is relevant and admissible in order to determine the content of such proposals; because they must be ‘open’ to all legislators, and transparent to the community, the evidence must be publicly available. This article summarizes the main theses of the book, and subjects them to critical examination. It concludes that the book adds considerable depth, rigour and theoretical insight to our understanding of these issues. But it also suggests that his argument is vulnerable to criticism at a few points, at least one of which is crucial. The argument needs a better account of what it is that constitutes the content of particular proposals when they are put to the legislature for enactment. (shrink)

In his recent book Interpretation and Legal Theory , Andrei Marmor makes a number of claims about meaning and interpretation, both in general and in law, which I will argue are mistaken. Actually, there is some confusion in his book between what I take to be his “official” view of the nature of meaning and interpretation, and a very different view which keeps surfacing despite his official rejection of it. I will argue that this alternative, rejected view, when properly developed, (...) is more plausible than his official view, and that the difference between them is of considerable practical consequence for legal interpretation. What is at stake is the role of legislative intention. The alternative view denies Marmor's claim that the meaning of a statute is conceptually independent of the intention or purpose which the legislature had in enacting it. It should be said at the outset that I will focus on just three of the eight chapters in Marmor's book, which contains many virtues that are untouched by my critique. (shrink)
