Condorcet's jury theorem shows that when the members of a group have noisy but independent information about what is best for the group as a whole, majority decisions tend to outperform dictatorial ones. When voting is supplemented by communication, however, the resulting interdependencies between decision makers can strengthen or undermine this effect: they can facilitate information pooling, but also amplify errors. We consider an intriguing non-human case of independent information pooling combined with communication: the case of nest-site choice by honeybee (...) (Apis mellifera) swarms. It is empirically well documented that when there are different nest sites that vary in quality, the bees usually choose the best one. We develop a new agent-based model of the bees' decision process and show that its remarkable reliability stems from a particular interplay of independence and interdependence between the bees.

Jessica du Toit wonders if our relationship with our pets can be morally defended.

Quality of life considerations should be central to moral decisionmaking in medicine. The formula QL = NE × (H + S) identifies the central components in determinations of quality of life. Critics have confused the validity of this formal statement and its use as a substantive guide in clinical situations.

This addendum to [2] shows that the set of tautological quantum logical propositional formulas for a finite dimensional vector space Cⁿ is different for every n, affirmatively answering a question posed therein.

Are they needed? To be sure. The Darwinian industry, industrious though it is, has failed to provide texts of more than a handful of Darwin's books. If you want to know what Darwin said about barnacles (still an essential reference to cirripedists, apart from any historical importance) you are forced to search shelves, or wait while someone does it for you; some have been in print for a century; various reprints have appeared and since vanished." -Eric Korn,Times Literary Supplement Charles (...) Robert Darwin (1880-1882) has been widely recognized since his own time as one of the most influential writers in the history of Western thought. His books were widely read by specialists and the general public, and his influence had been extended by almost continuous public debate over the last 130 years. New York University Press' edition makes it possible for the first time to review Darwin's public literary output as a whole, plus his scientific journal articles, his private notebooks, and his correspondence. This is the first complete edition containing all of Darwin's published books, featuring definitive texts recording original paginations with Darwin's indexes retained. All illustrations and plates are presented, inclucing 82 color plates of birds and mammals and several folding maps and plates. The set also features a general introduction and index, and textural introductions in each volume. (shrink)

Much of twentieth- and twenty-first-century theorizing about cognitive processes, whether in philosophy of mind, cognitive science, cognitive psychology, or related disciplines, spins accounts of cognition totally devoid of any consideration of cognition as an attribute of animals making a living (or not) in various habitats. A significant shift in discussions of mind and cognition follows if we take seriously the fact that humans are animals, products of evolutionary processes and situated squarely within suites of ecosystems. Ignoring evolutionary history is an (...) easy step to take when the starting places for understanding mind and cognition are relatively “sophisticated” mental accomplishments such as .. (shrink)

Sociologists have largely ignored the role of animals in society. This article argues that human-animal interaction is a topic worthy of sociological consideration and applies a sociological analysis to one problematic aspect of human-animal relationships - animal cruelty. The article reformulates animal cruelty, traditionally viewed using a psychopathological model, from a sociological perspective.The article identifies social and cultural factors related to the occurrence of animal cruelty. Ultimately, animal cruelty is a serious social problem that deserves attention in its own right, (...) not just because of its association with human violence. (shrink)

This transcription of notes made by Charles Darwin during the voyage of H. M. S. Beagle records his observations of the animals and plants that he encountered, and provides a valuable insight into the intellectual development of one of our most influential scientists. Darwin drew on many of these notes for his well known Journal of Researches (1839), but the majority of them have remained unpublished. This volume provides numerous examples of his unimpeachable accuracy in describing the wide range of (...) animals seen in the course of his travels, and of his closely analytical approach towards every one of his observations. Only at the very end of the voyage were his first doubts about the immutability of species expressed consciously, but here are to be found the initial seeds of his theory of evolution, and of the fields of behavioural and ecological study of which he was one of the founding fathers.

Frank Balfour was regarded by his colleagues as one of the greatest biologists of his day and Charles Darwin’s successor, yet the young aristocrat died in a climbing accident before his thirty-first birthday. Reactions to his death reveal much about the image of science and scientists in late-Victorian Britain. In this paper I examine the development of the Cambridge school of animal morphology, headed by Balfour, and the interdependence of his research reputation and his charisma. Contemporaries praised his gentlemanly qualities, (...) making his aristocratic background a part of his scientific character. Yet his reputation for good judgement and his abilities as a leader were severely tested when it began to emerge that the accident that killed Balfour and his guide might have been prevented. Nonetheless, the image of Balfour that emerges from his obituaries is that of a noble hero and outstanding scientist, who lived on in the memories of all who knew him. (shrink)

The Plymouth Laboratory of the Marine Biological Association of the United Kingdom (1884) was founded in 1888. In addition to conducting morphological and other biological research, the founders of the laboratory aimed at promoting research in experimental zoology which will be used in this paper as a synonym for e. g. experimental embryology, comparative physiology or general physiology. This dream was not fully realized until 1920. The Great War and its immediate aftermath had a positive impact on the development (...) of the Plymouth Laboratory. The war greatly upset the operation of the Zoological Station in Naples and the ensuing crisis in its operations was closely related to the establishment of the physiological department in Plymouth in 1920. Two other key factors in the Plymouth story were the establishment of the Development Fund in 1909, which began contributing funds to the Plymouth Laboratory in 1912, and the patronage of the Cambridge zoologist George P. Bidder (1863-1954). This paper will focus on the combined influence of the Development Fund and Bidder on the development of the Plymouth Laboratory from around 1902 through the early 1920s, and the important role the laboratory played in promoting experimental zoology in Britain in the 1920s.

There are three principal philosophical-scientific encyclopaedias written in Hebrew during the Middle Ages: Yehudah ha-Cohen's Midrash ha-okmah, rather than such texts as pseudo-Aristotle 's De lapidibus and Nicolaus Damascenus' De plantis. In particular, Falaquera's encyclopaedia represents the most convincing effort to provide a truly scientific discussion of mineralogy and botany, comparable to that of his contemporary Albert the Great, and based upon the Brethren, Avicenna and, maybe, some lost works by Averroes.

In the final sessions of the first year of his seminar on The Beast & the Sovereign, Jacques Derrida takes up the question of modernity as the epoch of biopolitics. In a remarkable close reading, he critiques Michel Foucault’s and Giorgio Agamben’s reflections on the threshold of biopolitical modernity, both in terms of conceptual content and, especially in the latter’s case, style. He takes as a prominent example the revolutionary transformation from princely menagerie to public zoological garden, as well as (...) Carl Hagenbeck’s subsequent “revolution” in zoo design, which inaugurate, he suggests, not a new biopolitical apparatus of power/ knowledge, but only a different form of the same fundamental structure of ..
