Landauer's principle, often regarded as the basic principle of the thermodynamics of information processing, holds that any logically irreversible manipulation of information, such as the erasure of a bit or the merging of two computation paths, must be accompanied by a corresponding entropy increase in non-information-bearing degrees of freedom of the information-processing apparatus or its environment. Conversely, it is generally accepted that any logically reversible transformation of information can in principle be accomplished by an appropriate physical mechanism operating in a (...) thermodynamically reversible fashion. These notions have sometimes been criticized either as being false, or as being trivial and obvious, and therefore unhelpful for purposes such as explaining why Maxwell's Demon cannot violate the second law of thermodynamics. Here I attempt to refute some of the arguments against Landauer's principle, while arguing that although in a sense it is indeed a straightforward consequence or restatement of the Second Law, it still has considerable pedagogic and explanatory power, especially in the context of other influential ideas in nineteenth and twentieth century physics. Similar arguments have been given by Jeffrey Bub. (shrink)

In their article, ‘That is not dead which can eternal lie: the aestivation hypothesis for resolving Fermi’s paradox’, Sandberg et al. try to explain the Fermi paradox by claiming that Landauer’s principle implies that a civilization can in principle perform far more times more) irreversible logical operations if it conserves its resources until the distant future when the cosmic background temperature is very low. So perhaps aliens are out there, but quietly waiting. Sandberg et al. implicitly assume, however, that computer-generated (...) entropy can only be disposed of by transferring it to the cosmological background. In fact, while this assumption may apply in the distant future, our universe today contains vast reservoirs and other physical systems in non-maximal entropy states, and computer-generated entropy can be transferred to them at the adiabatic conversion rate of one bit of negentropy to erase one bit of error. This can be done at any time, and is not improved by waiting for a low cosmic background temperature. Thus aliens need not wait to be active. As Sandberg et al. do not provide a concrete model of the effect they assert, we construct one and show where their informal argument goes wrong. (shrink)

This paper examines an issue that is becoming increasingly relevant as the pressures of a warming planet, changing climate and changing ecosystems ramp up. The broad context for the paper is the intragenerational, intergenerational, and interspecies equity implications of changing the climate and the value orientations of adapting to such change. In addition, the need to stabilize the planetary climate by urgent mitigation of change factors is a foundational ethical assumption. In order to avoid further animal and plant extinctions, or (...) at the very least, their increased vulnerability to becoming rare and endangered; the systematic assisted colonization of “at risk” species is being seriously considered by scientists and managers of biodiversity. The more practical aspects of assisted colonization have been covered in the conservation biology literature; however, the ethical implications of such actions have not been extensively examined. Our discussion of the value issues, using a novel case study approach, will rectify the limited ethical analysis of the issue of assisted colonization of species in the face of climate change pressures. Beyond sustainability ethics, both animal and environmental ethical approaches will be used and intrinsic versus instrumental value orientations in the literature shall form the basis of our discussion. After the application of all the ethical approaches to the case studies, we conclude that without mitigation and the prospect of a future stable climate, assisted colonization will be involved in an inherently unethical process and a “move and lose it” outcome. With mitigation, there is wide-ranging ethical support for assisted colonization. (shrink)

The last 20 years have seen the development of a new form of therapy, compassion focused therapy. Although CFT has a growing evidence base, there have been few studies of CFT outside of an Anglo-European cultural context. In this paper, we ask: Might a CFT-based approach be of value for Indigenous Australians? If so, what kind of cultural adaptations might be needed? We report the findings from a pilot study of an arts-based compassion skills training group, in which usual CFT (...) group processes were significantly adapted to meet the needs of Indigenous Australians. At face value, CFT appeared to be a promising approach to enhancing the social and emotional wellbeing of Australia’s Indigenous peoples. However, despite initial consultations with Indigenous health professionals, the first attempts to offer a more conventional group-based CFT to Indigenous clients were largely unsuccessful. Following a review and advice from two Indigenous clients, we combined elements of CFT with visual arts to develop a new approach, “arts-based compassion skills training”. This paper reports an evaluation of this pilot ABCST group. The group had 6 × 4 h sessions of ABCST, facilitated by two psychologists and two artists. There were 10 participants, who attended between 2 and 6 sessions: five were clients, five were health professionals. Between 1 and 3 months later, six of the participants were interviewed. Qualitative analysis of interview data identified that two key processes—creating a positive group atmosphere and channeling compassion skills training through the medium of visual arts—led to four positive outcomes for participants: planting the seeds of new understandings, embodying the skills of compassion, strengthening relationships with others, and evolving a more self-compassionate relationship. We suggest that the preliminary results are sufficiently encouraging to warrant further development of ABCST in Indigenous communities. (shrink)

In the Spring of 1944, an informal discussion took place in Cambridge between Mr. R. S. Whipple, Professor Allan Ferguson and Mr. F. H. C. Butler, concerning the formation of a national Society for the History of Science. This is the opening sentence of the inaugural issue of the Bulletin of the British Society for the History of Science, the Society's first official publication. Butler himself was the author of this outline account of the subsequent approach to the Royal Society, (...) the parallel moves to establish a National Committee of the International Academy of the History of Science, the formation of a provisional committee to prepare a draft constitution for a national society, and the proceedings of the first Annual General Meeting in May 1947. Whipple had been in Cambridge to discuss his offer to present his collection of old scientific instruments to the University and the possible foundation of a new museum, and Butler, as Secretary of the History of Science Committee in Cambridge, was the chief mover in both this development and an initiative coupled with it to establish a department of the history of science.

In this essay I first provide a brief explanation of the principle of double effect (PDE) and the propositions that it entails regarding the distinction betweenintention and foresight (I/F distinction) and the distinction’s relevance to ethical evaluation. Then I address several recent critiques of PDE and the I/F distinctionby influential ethicists including Judith Jarvis Thomson, Tom Beauchamp and James Childress, and Jonathan Bennett. I argue that none of these critiques issuccessful. In the process of refuting the critiques, I also (...) give prima facie reason to believe that the I/F distinction is relevant to evaluation of agents and their actions and that PDE is a defensible ethical principle.

Plurals had a slow start in the history of formal semantics; a significant explosion of innovations didn’t come until the 1980s. In this paper, I offer a picture of developments by noting not only important achievements but also reflecting on the state of thinking about plurals at various periods—what issues or phenomena were not even noticed, what puzzles had started to get attention, and what innovations made the biggest changes in how people thought about plurals. I divide the epochs roughly (...) into decades: before formal semantics ; the first decade of formal semantics—the 1970s, with early work by Montague and Bennett and landmark work on bare plurals by Carlson; the 1980s, when work by Link, Scha, Krifka, Landman, Roberts, and others significantly changed the landscape; and the 1990s, where I mention some key work by Lasersohn and Schwarzschild and stop there, although there was much more work in the 1990s. I don’t discuss the twenty-first century at all because it’s not very historical yet. (shrink)

"My energies for near a lifetime have been used almost entirely to win such prominence as I could in outdoor photography."--H. H. Bennett Henry Hamilton Bennett became a celebrated photographer in the half-century following the American Civil War. Bennett is admired for his superb depictions of dramatic landscapes of the Dells of the Wisconsin River and also for his many technical innovations in photography, including a stop-action shutter and a revolving solar printing house that is now housed (...) at the Smithsonian Institution. With his instantaneous shutter, he gained recognition for his striking images of moving subjects, such as lumber raftsmen shooting the river rapids and his son Ashley leaping in midair from a bluff to the craggy pillar of Stand Rock. Less well-known are Bennett's splendid urban photographs of nineteenth-century Chicago, Milwaukee, and St. Paul. This engaging biography of H. H. Bennett tells his life story, illustrated throughout with his remarkable photographs, some of them rarely viewed before. It draws on the photographer's own letters and journals, along with other family documents, to portray the sweep of his career and personal life. An important figure in the history of photography, he also contributed to the growth of American tourism: his nationally distributed stereoscopic views of Dells rock formations and his portraits of local Ho-Chunk Indians played a significant role in creating the Wisconsin Dells as the popular tourist destination it is today. Despite personal challenges--a crippling Civil War injury, the death of his first wife, and continual financial worries--Bennett produced an extensive portfolio that captures the midwestern culture of his time. He accepted commissions in the 1890s to document Chicago's modern skyscrapers, grand residences of Milwaukee's entrepreneurs and sailing ships in its harbor, enormous scenic panoramas along the routes of Wisconsin railroads, and sparkling ice palaces lit by fireworks at the St. Paul Winter Carnival.

Many have argued against the claim that Plato posited the mathematical objects that are the subjects of Metaphysics M and N. This paper shifts the burden of proof onto these objectors to show that Plato did not posit these entities. It does so by making two claims: first, that Plato should posit the mathematical Intermediates because Forms and physical objects are ill suited in comparison to Intermediates to serve as the objects of mathematics; second, that their utility, combined with Aristotle’s (...) commentary on Plato’s posit of Intermediates, provides good reason to conclude that Plato did posit them.

The essay published here in English was one of the earliest documents of the birth of the form of idealism which Giovanni Gentile called “Actual Idealism.” The most celebrated full-length statement of it was published in 1916 as General Theory of the Spirit as Pure Act. But there is no other essay in which the relation between Gentile’s view and the great German tradition from which it derives is made so plain.
