Sketching is a powerful means of working out and communicating ideas. Sketch understanding involves a combination of visual, spatial, and conceptual knowledge and reasoning, which makes it both challenging to model and potentially illuminating for cognitive science. This paper describes CogSketch, an ongoing effort of the NSF-funded Spatial Intelligence and Learning Center, which is being developed both as a research instrument for cognitive science and as a platform for sketch-based educational software. We describe the idea of open-domain sketch understanding, the (...) scientific hypotheses underlying CogSketch, and provide an overview of the models it employs, illustrated by simulation studies and ongoing experiments in creating sketch-based educational software.

Bayesian probability is normally defined over a fixed language or eventspace. But in practice language is susceptible to change, and thequestion naturally arises as to how Bayesian degrees of belief shouldchange as language changes. I argue here that this question poses aserious challenge to Bayesianism. The Bayesian may be able to meet thischallenge however, and I outline a practical method for changing degreesof belief over changes in finite propositional languages.

Drawing on philosophy, political and social theory, decision-theory, economics, psychology, history and literature, Jon Elster's classic book Sour Grapes continues and complements the arguments of his acclaimed earlier book, Ulysses and the Sirens. Elster begins with an analysis of the notation of rationality, before tackling the notions of irrational behavior, desires and belief with highly sophisticated arguments that subvert the orthodox theories of rational choice. Presented in a fresh series livery and with a specially commissioned preface written by Richard Holton, (...) illuminating its continuing importance to philosophical enquiry, Sour Grapes has been revived for a new generation of readers.

The question Jon Elster addresses in this challenging book is what binds societies together and prevents them from disintegrating into chaos and war. He analyses two concepts of social order: stable, predictable patterns of behaviour, and co-operative behaviour. The book examines various aspects of collective action and bargaining from the perspective of rational-choice theory and the theory of social norms. It is a fundamental assumption of the book that social norms provide an important kind of motivation for action that is (...) irreducible to rationality. The book represents a major statement by Elster, which will be of particular interest to political scientists, political philosophers, sociologists, and economists. (shrink)

A systematic, critical examination of Karl Marx's social theories and their philosophical presuppositions. Through extensive discussions of the texts Jon Elster offers a balanced and detailed account of Marx's views that is at once sympathetic, undogmatic and rigorous. Equally importantly he tries to assess 'what is living and what is dead in the philosophy of Marx', using the analytical resources of contemporary social science and philosophy. Professor Elster insists on the need for microfoundations in social science and provides a systematic (...) criticism of functionalism and teleological thinking in Marx. He argues that Marx's economic theories are largely wrong or irrelevant; historical materialism is seen to have only limited plausibility ; Marx's most lasting achievements are the criticism of capitalism in terms of alienation and exploitation and the theory of class struggle, politics and ideology under capitalism, though in these areas too Elster enters substantial qualifications. The book should take its place as the most comprehensive and sophisticated modern study available. (shrink)

Logic is a field studied mainly by researchers and students of philosophy, mathematics and computing. Inductive logic seeks to determine the extent to which the premises of an argument entail its conclusion, aiming to provide a theory of how one should reason in the face of uncertainty. It has applications to decision making and artificial intelligence, as well as how scientists should reason when not in possession of the full facts. In this work, Jon Williamson embarks on a quest to (...) find a general, reasonable, applicable inductive logic (GRAIL), all the while examining why pioneers such as Ludwig Wittgenstein and Rudolf Carnap did not entirely succeed in this task.

Much attention has been focused in recent years on the ethical acceptability of physicians receiving gifts from drug companies. Professional guidelines recognize industry gifts as a conflict of interest and establish thresholds prohibiting the exchange of large gifts while expressly allowing for the exchange of small gifts such as pens, note pads, and coffee. Considerable evidence from the social sciences suggests that gifts of negligible value can influence the behavior of the recipient in ways the recipient does not always realize. (...) Policies and guidelines that rely on arbitrary value limits for gift-giving or receipt should be reevaluated. (shrink)

A concise and comprehensive introduction to Marx's social, political and economic thought for the beginning student. Jon Elster surveys in turn each of the main themes of marxist thought: methodology, alienation, economics, exploitation, historical materialism, classes, politics, and ideology; in a final chapter he assesses 'what is living and what is dead in the philosophy of Marx'. The emphasis throughout is on the analytical structure of Marx's arguments and the approach is at once sympathetic, undogmatic, and rigorous.

We first discuss Michael Dummett’s philosophy of mathematics and Robert Brandom’s philosophy of language to demonstrate that inferentialism entails the falsity of Church’s Thesis and, as a consequence, the Computational Theory of Mind. This amounts to an entirely novel critique of mechanism in the philosophy of mind, one we show to have tremendous advantages over the traditional Lucas-Penrose argument.

We evaluate here the performance of four models of cross-situational word learning: two global models, which extract and retain multiple referential alternatives from each word occurrence; and two local models, which extract just a single referent from each occurrence. One of these local models, dubbed Pursuit, uses an associative learning mechanism to estimate word-referent probability but pursues and tests the best referent-meaning at any given time. Pursuit is found to perform as well as global models under many conditions extracted from (...) naturalistic corpora of parent-child interactions, even though the model maintains far less information than global models. Moreover, Pursuit is found to best capture human experimental findings from several relevant cross-situational word-learning experiments, including those of Yu and Smith (), the paradigm example of a finding believed to support fully global cross-situational models. Implications and limitations of these results are discussed, most notably that the model characterizes only the earliest stages of word learning, when reliance on the co-occurring referent world is at its greatest.

It is tempting to analyse causality in terms of just one of the indicators of causal relationships, e.g., mechanisms, probabilistic dependencies or independencies, counterfactual conditionals or agency considerations. While such an analysis will surely shed light on some aspect of our concept of cause, it will fail to capture the whole, rather multifarious, notion. So one might instead plump for pluralism: a different analysis for a different occasion. But we do not seem to have lots of different concepts of cause (...) – just one eclectic notion. The resolution of this conundrum, I think, requires us to accept that our causal beliefs are generated by a wide variety of indicators, but to deny that this variety of indicators yields a variety of concepts of cause. This focus on the relation between evidence and causal beliefs leads to what I call epistemic causality. Under this view, certain causal beliefs are appropriate or rational on the basis of observed evidence; our notion of cause can be understood purely in terms of these rational beliefs. Causality, then, is a feature of our epistemic representation of the world, rather than of the world itself. This yields one, multifaceted notion of cause. (shrink)

Mental Processes in the Human Brain provides an integrative overview of the rapid advances and future challenges in understanding the neurobiological basis of mental processes that are characteristically human. With chapters from leading figures in the brain sciences, it will be essential for all those in the cognitive and brain sciences.

Over the last decade or so, political scientists and legal academics have begun studying the linkages between ideologies, on one hand, and legal principles and policy outcomes on the other. This book is the first to bring many of the world's experts on those topics together to examine the sometimes unsettling interactions between psychology, ideology, and law.

Abstract Scholars find that political elites are badly polarized over a large range of policy issues, but they tend to agree that the mass public is much more ambivalent. The abortion war in particular is regarded as one in which millions of ambivalent citizens are caught in the crossfire of polarized activists. Yet even abortion activists struggle to escape the very ambivalent sentiments that plague ordinary Americans. These common sentiments even exert a moderating influence on both movements in ways that (...) are consistent with the preferences of the American public. They also suggest that liberalism may be mired in permanent conflict and ambivalence over the scope of basic human rights. (shrink)

Salmon was the first to speak explicitly of paradoxes of kinematics. In this short note I introduce a new class of infinity puzzles. Following natural terminology, they should actually be called static paradoxes.

When a proposition is established, it can be taken as evidence for other propositions. Can the Bayesian theory of rational belief and action provide an account of establishing? I argue that it can, but only if the Bayesian is willing to endorse objective constraints on both probabilities and utilities, and willing to deny that it is rationally permissible to defer wholesale to expert opinion. I develop a new account of deference that accommodates this latter requirement.

In this paper a model in particle dynamics of a well-known supertask is constructed. As a consequence, a new and simple result about the failure of determinism of classical particle dynamics can be proved which is related to the non-existence of boundary conditions at spatial infinity. This result is much more accessible to the non-technical reader than similar ones in the scientific literature.

Practical reasoning requires decision—making in the face of uncertainty. Xenelda has just left to go to work when she hears a burglar alarm. She doesn’t know whether it is hers but remembers that she left a window slightly open. Should she be worried? Her house may not be being burgled, since the wind or a power cut may have set the burglar alarm off, and even if it isn’t her alarm sounding she might conceivably be being burgled. Thus Xenelda can (...) not be certain that her house is being burgled, and the decision that she takes must be based on her degree of certainty, together with the possible outcomes of that decision.

After introducing a range of mechanistic theories of causality and some of the problems they face, I argue that while there is a decisive case against a purely mechanistic analysis, a viable theory of causality must incorporate mechanisms as an ingredient. I describe one way of providing an analysis of causality which reaps the rewards of the mechanistic approach without succumbing to its pitfalls.

I. SummaryRuth Boeker's Locke on Persons and Personal Identity is a profound treatment of Locke's views on the nature and identity of human persons. The book is divided roughly into two halves. The first half (Chapters 1–6 and 8) focuses on providing a philosophically sophisticated interpretation of Locke that engages with the most recent secondary literature. Chapter 3, for instance, includes an important contribution to scholarly debates about Locke's sortal-relative account of identity in the Essay II.xxvii.§7–8. Some (the coincidence theorists) (...) have argued that Locke's claim that there are different persistence conditions for a ‘man’ (human animal) and the ‘mass of matter’ that occupies the same spatio-temporal location as the man entails that there are two, coincident material objects. Others (the relative identity theorists) argue that Locke holds that there is ontologically one and only one material object at any spatio-temporal location—a single object that can be attributed different identity conditions when considered under different sortals.

Objective Bayesianism has been criticised for not allowing learning from experience: it is claimed that an agent must give degree of belief ½ to the next raven being black, however many other black ravens have been observed. I argue that this objection can be overcome by appealing to objective Bayesian nets, a formalism for representing objective Bayesian degrees of belief. Under this account, previous observations exert an inductive influence on the next observation. I show how this approach can be used (...) to capture the Johnson-Carnap continuum of inductive methods, as well as the Nix-Paris continuum, and show how inductive influence can be measured.

Preservation and interpolation results are obtained for L ∞ω and sublogics $\mathscr{L} \subseteq L_{\infty\omega}$ such that equivalence in L can be characterized by suitable back-and-forth conditions on sets of partial isomorphisms.

Although the impact of so-called “sponsorship bias” has been the subject of increased attention in the philosophy of science, what exactly constitutes its epistemic wrongness is still debated. In this paper, I will argue that neither evidential accounts nor social–epistemological accounts can fully account for the epistemic wrongness of sponsorship bias, but there are good reasons to prefer social–epistemological to evidential accounts. I will defend this claim by examining how both accounts deal with a paradigm case from medical epistemology, recently (...) discussed in a paper by Bennett Holman. I will argue that evidential accounts cannot adequately capture cases of sponsorship bias that involve the manufacturing of certainty because of their neutrality with respect to the role of non-epistemic values in scientific practice. If my argument holds, it further highlights the importance of integrating social and ethical concerns into epistemological analysis, especially in applied contexts. One can only properly grasp sponsorship bias as an epistemological problem if one resists the methodological tendency to analyze social, ethical, and epistemological issues in isolation from each other.

This chapter addresses two questions: what are causal relationships? how can one discover causal relationships? I provide a survey of the principal answers given to these questions, followed by an introduction to my own view, epistemic causality, and then a comparison of epistemic causality with accounts provided by Judea Pearl and Huw Price.

In this paper a simple model in particle dynamics of a well-known supertask is constructed (the supertask was introduced by Max Black some years ago). As a consequence, a new and simple result about creation ex nihilo of particles can be proved compatible with classical dynamics. This result cannot be avoided by imposing boundary conditions at spatial infinity, and therefore is really new in the literature. It follows that there is no reason why even a world of rigid spheres should (...) be eternal, as has been erroneously assumed, especially since the time of Newton. (shrink)

The moral psychology of sympathy is the linchpin of the sentimentalist moral theories of both David Hume and Adam Smith. In this paper, I attempt to diagnose the critical differences between Hume's and Smith's respective accounts of sympathy in order to argue that Smithian sympathy is more properly suited to serve as a basis for impartial moral evaluations and judgments than is Humean sympathy. By way of arguing this claim, I take up the problem of overcoming sympathetic partiality in the (...) construction of a moral point of view, acknowledged by both writers, as my primary platform. My contention is that Humean sympathy is too mechanistic to actually deliver an impartial adjudicatory perspective, and that Smithian sympathy, with its evaluative, imaginative components, succeeds where Hume's account falls short. The paper is comprised of six sections: (i) introductory remarks, (ii) a discussion of Humean sympathy, (iii) a discussion of Smithian sympathy and its distinctness, (iv) a critical analysis of Hume's attempt to correct for sympathetic partiality in the construction of the judicial spectator's general point of view, (v) a critical discussion of sympathetic partiality in Smithian sympathy & (vi) a critical analysis of Smith's construction of the impartial spectator perspective as a moral point of view.

"In his The Condition of the Working Class in England, Friedrich Engels outlines systematically the miseries of the workers in England in the context of industrialization. A key to his argument concerns the interface between the human body and the machine. In this article I argue that Engels provides a kind of a phenomenology of the body in his analyses of the relation of the worker to the new machines. The limited secondary literature on Marxism and phenomenology has not been (...) attentive to the detailed attention that is given to the body of the worker in this book. Keywords: handwork, machines, technology, Industrial Revolution, Friedrich Engels, factory work ". (shrink)

In this paper, I develop and respond to a novel objection to Conciliatory Views of disagreement. Having first explained Conciliationism and the problem of divine hiddenness, I develop an objection that Conciliationism exacerbates the problem of divine hiddenness. According to this objection, Conciliationism increases God’s hiddenness in both its scope and severity, and is thus incompatible with God’s existence (or at least make God’s existence quite improbable). I respond to this objection by showing that the problem of divine hiddenness is (...) not made any worse by Conciliationism. (shrink)

Reparations is an idea whose time has come. From civilian victims of war in Iraq and South America to descendents of slaves in the US to citizens of colonized nations in Africa and south Asia to indigenous peoples around the world--these groups and their advocates are increasingly arguing for the importance of addressing historical injustices that have long been either ignored or denied. This volume contributes to these debates by focusing the attention of a group of highly distinguished international experts (...) on the ways that reparations claims figure in contemporary political and social justice movements. Four broad types of reparations claims are examined, those involving indigenous peoples, the legacy of slavery in the United States, victims of war and conflict, and colonialism. In each instance, scholars and activists argue about the character of the injustice for which reparations are owed, why it is important to take these demands seriously, and what form redress should take. The aim is not consensus but to exhibit better the complexity of the issues involved--a goal which the interdisciplinary nature of the volume furthers--as well as the importance of taking seriously both conceptual issues and the actual politics of reparations.

We show that several theorems on ordinal bounds in different parts of logic are simple consequences of a basic result in the theory of global inductive definitions.

Bayesian networks may either be treated purely formally or be given an interpretation. I argue that current foundations are problematic, and put forward new foundations which involve aspects of both the interpreted and the formal approaches.

Spinoza's philosophical anthropology is reconstructed with a view to its relevance to theoretical and practical problems in social psychology. An attempt is made to show how he conceives the interrelations between cognitions, sentiments (i.e. emotions and attitudes), and interests (i.e. drives and desires) as relational concepts and as anchored in social interaction rather than in a purely individualistic conception of man. Spinoza's determinism is interpreted as a personal and social causation, rather than a physical, causal determinism, and his theory of (...) cognition is interpreted partly in relation to the Hegelian distinction between undialectical and dialectical thinking.
