Some researchers have attributed deviations from selfish behavior to fairness. Violations of fairness theories, however, are observed in experimental dictator games with transfer rates greater than 1 (a transfer of x from the dictator yields an income of tx for the beneficiary, where x < tx): the dictator’s final income is less than the beneficiary’s. We theoretically propose that dictator giving also involves altruism, further supporting our claim with empirical evidence from four separate samples of dictator game experiments. Our nonlinear (...) specification allows the relative measurement of the independent motives in dictator behavior. (shrink)

Automated reasoning about uncertain knowledge has many applications. One difficulty when developing such systems is the lack of a completely satisfactory integration of logic and probability. We address this problem directly. Expressive languages like higher-order logic are ideally suited for representing and reasoning about structured knowledge. Uncertain knowledge can be modeled by using graded probabilities rather than binary truth-values. The main technical problem studied in this paper is the following: Given a set of sentences, each having some probability of being (...) true, what probability should be ascribed to other (query) sentences? A natural wish-list, among others, is that the probability distribution (i) is consistent with the knowledge base, (ii) allows for a consistent inference procedure and in particular (iii) reduces to deductive logic in the limit of probabilities being 0 and 1, (iv) allows (Bayesian) inductive reasoning and (v) learning in the limit and in particular (vi) allows confirmation of universally quantified hypotheses/sentences. We translate this wish-list into technical requirements for a prior probability and show that probabilities satisfying all our criteria exist. We also give explicit constructions and several general characterizations of probabilities that satisfy some or all of the criteria and various (counter) examples. We also derive necessary and sufficient conditions for extending beliefs about finitely many sentences to suitable probabilities over all sentences, and in particular least dogmatic or least biased ones. We conclude with a brief outlook on how the developed theory might be used and approximated in autonomous reasoning agents. Our theory is a step towards a globally consistent and empirically satisfactory unification of probability and logic. (shrink)

Experiential evidence shows that pain is associated with common meanings. These include a meaning of threat or danger, which is experienced as immediately distressing or unpleasant; cognitive meanings, which are focused on the long-term consequences of having chronic pain; and existential meanings such as hopelessness, which are more about the person with chronic pain than the pain itself. This interdisciplinary book - the second in the three-volume Meanings of Pain series edited by Dr Simon van Rysewyk - aims to better (...) understand pain by describing experiences of pain and the meanings these experiences hold for the people living through them. The lived experiences of pain described here involve various types of chronic pain, including spinal pain, labour pain, rheumatic pain, diabetic peripheral neuropathic pain, fibromyalgia, complex regional pain syndrome, endometriosis-associated pain, and cancer-related pain. Two chapters provide narrative descriptions of pain, recounted and interpreted by people with pain. Language is important to understanding the meaning of pain since it is the primary tool human beings use to manipulate meaning. As discussed in the book, linguistic meaning may hold clues to understanding some pain-related experiences, including the stigmatisation of people with pain, the dynamics of patient-clinician communication, and other issues, such as relationships between pain, public policy and the law, and attempts to develop a taxonomy of pain that is meaningful for patients. Clinical implications are described in each chapter. This book is intended for people with pain, their family members or caregivers, clinicians, researchers, advocates, and policy makers. (shrink)

In the current debate on art, thought on time has commanded a prominent position. Do we live in a posthistorical time? Has objective art historical time and belief in a continual progress shifted to a more subjective experience of the ephemeral? Has history fallen away and, if so, what does this mean for the future of art? How does a visual archive relate to artistic memory? This volume investigates positions, arguments and comments regarding the stated theme. Philosophers and theorists explore (...) the subject matter theoretically. Curators articulate the practice of art. The participants are: Hans Belting, Jan Bor, Peter Bürger, Bart Cassiman, Leontine Coelewij, Hubert Damisch, Arthur C. Danto, Bart De Baere, Okwui Enwezor, Kasper König, Sven Lütticken, Manifesta, Hans Ulrich Obrist, Donald Preziosi, Survival of the Past Project, Ernst Van Alphen, Kirk Varnedoe, Gianni Vattimo, and Kees Vuyk.

This interview with Jeremy Waldron covers three topics. Firstly, we dealt with the methodology debate, that is, the discussion about how to proceed in analyzing the nature of law. Does the question ‘What is law?’ require a descriptive analysis of the concept of law or, rather, a normative exercise in political philosophy? Secondly, we spoke about the role of law in response to historic injustice, especially in relation to the restitution of property rights. On this topic Waldron vindicates the ‘supersession-thesis’, (...) the idea that, due to changed circumstances and the passage of time, historic injustices become superseded. The third section of the interview is devoted to Waldron’s perspective on the citation of foreign law by national judges. (shrink)

Media in Question sets the agenda for a revitalized debate on the hybrid communicative practices that constitute the postmodern media landscape: practices that cross the boundaries between fact and fiction, information and entertainment, public knowledge, and popular culture. In this challenging and provocative collection, the individual contributors rethink key issuesùthe meaning of the public interest, the quality of media performance, and deregulation. In the process they raise questions rarely addressed in normative media theories, for example, the ethics of sports reporting, (...) the moral reasoning in popular culture, and the required professional standards for infotainment genres such as reality television and gossip journalism. Accessible and wide-ranging, The Media in Question will be essential reading for students in mass communication and political communication studies. (shrink)

A substantial amount of recent work in natural language generation has focused on the generation of ‘‘one‐shot’’ referring expressions whose only aim is to identify a target referent. Dale and Reiter's Incremental Algorithm (IA) is often thought to be the best algorithm for maximizing the similarity to referring expressions produced by people. We test this hypothesis by eliciting referring expressions from human subjects and computing the similarity between the expressions elicited and the ones generated by algorithms. It turns out that (...) the success of the IA depends substantially on the ‘‘preference order’’ (PO) employed by the IA, particularly in complex domains. While some POs cause the IA to produce referring expressions that are very similar to expressions produced by human subjects, others cause the IA to perform worse than its main competitors; moreover, it turns out to be difficult to predict the success of a PO on the basis of existing psycholinguistic findings or frequencies in corpora. We also examine the computational complexity of the algorithms in question and argue that there are no compelling reasons for preferring the IA over some of its main competitors on these grounds. We conclude that future research on the generation of referring expressions should explore alternatives to the IA, focusing on algorithms, inspired by the Greedy Algorithm, which do not work with a fixed PO.

This paper asks why information should ever be expressed vaguely, re-assessing some previously proposed answers to this question and suggesting some new ones. Particular attention is paid to the benefits that vague expressions can have in situations where agreement over the meaning of an expression cannot be taken for granted. A distinction between two different versions of the above-mentioned question is advocated. The first asks why human languages contain vague expressions, the second question asks when and why a speaker should (...) choose a vague expression when communicating with a hearer. While the former question is purely theoretical, the latter has practical implications for the computational generation of utterances in Natural Language Generation (NLG). (shrink)

In recent years, social cognition approaches to human evolution and Material Engagement Theory have offered new theoretical resources to advance our understanding of the prehistoric hominin mind. To date, however, these two approaches have developed largely in isolation from one another. I argue that there is a gap between social- and material-centred approaches, and that this is precisely the sociomateriality of the appearance of ancestral hominin bodies, which evolved under selective pressure to develop increasingly complex, cooperative sociality. To get this (...) sociomaterial body in focus, I develop an esthesiological framework, appropriated from Merleau-Ponty (2003), for interpreting the expressive body in an evolutionary and comparative context. The guiding hypothesis of esthesiology is that before being rationality (social or material), “humanity is another corporeity” (Merleau-Ponty, 2003, p. 208). Esthesiology studies the appearance of the body and its sense organs as an intertwining locus of a sensing power (the ability to see, to touch, etc.) and a sensible character (the visible, touchable body). It is this dual-aspect character of the body that facilitates the most basic affective and sensorimotor modes of sociality. Examining these features from a comparative perspective, we find that the human body is distinctively suited to prosocial communication and cooperation: a more cooperative eye, an exposed and communicative skin. I thus propose a cooperative body hypothesis, by analogy with the cooperative eye hypothesis (Tomasello et al., 2007). Esthesiology provides a framework for integrating and interpreting a wide range of otherwise disconnected facts concerning human and nonhuman animal bodies, forms of life, cognition, and evolution, thereby bridging the gap between social cognition and material engagement perspectives. In doing so, however, it not only solves problems and proposes new directions of investigation, but also demands theoretical revisions from each. (shrink)
