Generalization is a fundamental problem solved by every cognitive system in essentially every domain. Although it is known that how people generalize varies in complex ways depending on the context or domain, it is an open question how people learn the appropriate way to generalize for a new context. To understand this capability, we cast the problem of learning how to generalize as a problem of learning the appropriate hypothesis space for generalization. We propose a normative mathematical framework for learning (...) how to generalize by learning inductive biases for which properties are relevant for generalization in a domain from the statistical structure of features and concepts observed in that domain. More formally, the framework predicts that an ideal learner should learn to generalize by either taking the weighted average of the results of generalizing according to each hypothesis space, with weights given by how well each hypothesis space fits the previously observed concepts, or by using the most likely hypothesis space. We compare the predictions of this framework to human generalization behavior with three experiments in one perceptual (rectangles) and two conceptual (animals and numbers) domains. Across all three studies we find support for the framework's predictions, including individual‐level support for averaging in the third study. (shrink)

Authored by an interdisciplinary team of experts, including historians, classicists, philosophers and theologians, this original collection of essays offers the first authoritative analysis of the multifaceted reception of Greek ethics in late antiquity and Byzantium, opening up a hitherto under-explored topic in the history of Greek philosophy. The essays discuss the sophisticated ways in which moral themes and controversies from antiquity were reinvigorated and transformed by later authors to align with their philosophical and religious outlook in each period. Topics examined (...) range from ethics and politics in Neoplatonism and ethos in the context of rhetorical theory and performance to textual exegesis on Aristotelian ethics. The volume will appeal to scholars and students in philosophy, classics, patristic theology, and those working on the history of education and the development of Greek ethics. (shrink)

Grace de Laguna’s philosophical work was bold and original. She was also able to connect together seemingly disparate strands of the pragmatic, metaphysical and psychological research going on around her, as Joel Katzav shows in his paper. This commentary gives some historical background to her academic career in an attempt to explain how she could have been forgotten as a philosopher. Social and institutional factors led to her work not being recognized when she wrote and thus sinking into obscurity in (...) philosophical circles afterwards. Although her work was initially widely read, her research seems not to have had any continuing direct impact on later developments in philosophy. However, it is crucial to restore her thought to its rightful place in the history of our subject. (shrink)

This volume is a new edition of a collection of problems in natural science and medicine which has been variously attributed to Aristotle and to Alexander of Aphrodisias; the collection includes material from both the Hellenistic and Roman periods.

This book explores "real" valuation through tracing the pragmatic meanings of "mattering." Employing Peirce's overall pragmatic method and realism to understand what we mean when we say something "matters," it encourages consideration of the practices we engage in, the values attached to those practices, and their consequences.

In recent years, Philosophy Departments at universities in China and worldwide have experienced a renaissance in discussion on Confucian thought. As the country draws from indigenous traditions, rather than leaning completely on the importation of Western liberalism and Marxism, Confucianism has critical implications for politics, ethics, and law in modern China. At the same time, democracy never left the conversation. Democratic concepts cannot be ignored and must be disposed of, acknowledged, or incorporated. The relationship between Confucianism and democracy has been (...) described by various authors as one of conflict, critique, compatibility, and hybridity. In this article, we examine a compatibility model, in which compatibility between Confucianism and democracy can be divided into four types: soft, hard, coexistence, and integration. We examine compatibility by examining “what is compatible” and “how compatibility can be achieved” so as to design speculative models for what a contemporary Confucian government would look like. Our focus is mainly political philosophy in order to explain the effect of cross-pollination of Confucian and democratic thought on political society. (shrink)

This essay is about a special kind of transformative choice that plays a key role in debates about permissivism, the view that some bodies of evidence permit more than one rational response. A prominent objection to this view contends that its defender cannot vindicate our aversion to arbitrarily switching between belief states in the absence of any new evidence. A prominent response to that objection tries to provide the desired vindication by appealing to the idea that arbitrary switching would involve (...) a special kind of transformative choice: the choice to change one’s epistemic standards, i.e., one’s commitments regarding the relative importance of achieving true belief and avoiding false belief. My first aims here are to argue that this response is unsuccessful and propose an alternative. My secondary aim is to consider how this discussion might bear on more general debates about transformative choice. (shrink)

Wahrend Friedrich Nietzsche als eine der bedeutendsten Figuren innerhalb der deutschen Kulturgeschichte gilt, wird sein Einfluss auf den juristischen Diskurs als marginal beurteilt. Es scheint, als hatten sich die Rechtsphilosophen und -theoretiker einer vertieften Auseinandersetzung mit dem Denker enthalten. Sophia Gluth hinterfragt diesen Umstand und beleuchtet, ob und wie theoretisierende Juristen mit Nietzsche umgegangen sind. Dabei deckt sie ein Phanomen auf, das bisher weder gesehen noch beschrieben wurde: die konstante Rezeption Friedrich Nietzsches in der Rechtswissenschaft. Untersucht werden die Rezeptionsansatze (...) vom Kaiserreich bis in die Gegenwart. Die juristischen Nietzsche-Lekturen u.a. des Freirechts, der "Konservativen Revolution", der Nationalsozialisten sowie der Postmoderne werden dabei stets eingebettet in ihre kulturelle und soziologische Umwelt. Erzahlt wird so eine - nicht zuletzt bedruckende - juristische Ideen- und Mentalitatsgeschichte des 20. Jahrhunderts. (shrink)

Algorithms for approximate Bayesian inference, such as those based on sampling (i.e., Monte Carlo methods), provide a natural source of models of how people may deal with uncertainty with limited cognitive resources. Here, we consider the idea that individual differences in working memory capacity (WMC) may be usefully modeled in terms of the number of samples, or “particles,” available to perform inference. To test this idea, we focus on two recent experiments that report positive associations between WMC and two distinct (...) aspects of categorization performance: the ability to learn novel categories, and the ability to switch between different categorization strategies (“knowledge restructuring”). In favor of the idea of modeling WMC as a number of particles, we show that a single model can reproduce both experimental results by varying the number of particles—increasing the number of particles leads to both faster category learning and improved strategy‐switching. Furthermore, when we fit the model to individual participants, we found a positive association between WMC and best‐fit number of particles for strategy switching. However, no association between WMC and best‐fit number of particles was found for category learning. These results are discussed in the context of the general challenge of disentangling the contributions of different potential sources of behavioral variability. (shrink)

This second edition of Basic Data of Plasma Physics is, in essence, a new book, for several reasons. First, so voluminous have been the research results in this area since the first edition of 1959 that the basic data themselves are greatly changed and enlarged. Second, whereas the earlier edition presented much of the material in verbal form, this one displays almost all of it in a consistent set of graphic figures. And, finally, this new edition is one of the (...) first implementations of computer-based information transfer, in which the basic data were searched out by means of a remote console tied into a central disk library containing an extensive collection of bibliographic information on physics literature.This last matter deserves further amplification, since the new techniques employed here are likely to be used more and more often in the future--because of the ever more rapidly expanding volume of research results just mentioned. Professor Brown, writing in Physics Today, summarizes his aims and methods:Any collection of data one can make these days is out of date before it is published. This is true, for example, of my Basic Data of Plasma Physics. In the book I tried to bring together in useful form the data of gaseous electronics and plasma physics upon which scientists base calculations and further work with basic parameters.Updating this book seemed an ideal computer experiment. I used the Information Retrieval Service of the TIP program not only to find material that has come out since publication of the book but also to arrange the program so that the computer could continue in the future to retrieve relevant information....The Technical Information Project, upon which this experiment is based, has programmed 25 physics journals from the past few years and The Physical Review from 1959 onto the IBM 7094 operated by Project MAC. Project MAC uses a compatible time-sharing system that is available by standard telephone connections....The TIP program contains title, author, reference and entire bibliography of every article covered by the computer....Entrance into the TIP system is made by choosing a key word or words most likely to be contained in the title of an article in a specific subject....in the revision of Basic Data of Plasma Physics the material is created in an open-ended form so that anyone with access to the computer program can search the literature for material that will appear after the report is printed. This feature of the bibliographic search by computers provides a new dimension to the published literature in book form which, without this open-ended feature, is out of date quite generally long before the actual publication date.

Discussions of the importance of including physics as part of a liberal education.

For the past 40 years, the 14-day rule has governed and, by defining a clear boundary, enabled embryo research and the clinical benefits derived from this. It has been both a piece of legislation and a rule of good practice globally. However, methods now allow embryos to be cultured for more than 14 days, something difficult to imagine when the rule was established, and knowledge gained in the intervening years provides robust scientific rationale for why it is now essential to (...) conduct research on later stage human embryos. In this paper, I argue that the current limit for embryo research in vitro should be extended to 28 days to permit research that will illuminate our beginnings as well as provide new therapeutic possibilities to reduce miscarriage and developmental abnormalities. It will also permit validation of potentially useful alternatives. Through consideration of current ethical arguments, I also conclude that there are no coherent or persuasive reasons to deny researchers, and through them humanity, the knowledge and the innovation that this will generate.

I argue that T.M. Scanlon's contractualist account of morality has difficulty accommodating our intuitions about the moral relevance of the number of people affected by an action. I first consider the "Complaint Model" of reasonable rejection, which restricts the grounds for an individual's rejection of a principle to its effects upon herself. I argue that it can accommodate our intuitions about numbers only if we assume that, whenever we do not know who will be affected, each individual may appeal only (...) to the _expected effects on her. This assumption, I suggest, leads to counterintuitive results in cases where, although we do not know who will be affected, we do know that _someone will be. I then consider two proposals to supplement the complaint model with a direct appeal to aggregation. I argue that both are open to serious objections. (shrink)

This book defends an original and pluralist theory of when and why discrimination wrongs people, in particular, through unfair subordination, through the violation of their right to a particular deliberative freedom, or through the denial to them of access to a basic good.
