Historians of technology have provided important accounts of technological innovation, but they rarely employ concepts which permit a rigorous analysis ofinvention as a mental or cognitive process. This article seeks to address this theoretical lacuna by using concepts adapted from cognitive psychology to compare the mental processes of two telephone inventors, Alexander Graham Bell and Thomas Edison. Specifically, we suggest that invention may be seen as a process in which inventors combine ideas with objects, or what we call mental models (...) and mechanical representations. The strategies by which inventors generate and manipulate these mental models and mechanical representations are what we refer to as heuristics. Using these concepts to narrate the development of the telephone, this article shows how invention can be interpreted as being much more than simply a mysterious act of individual genius. (shrink)

The technological breakthroughs and entrepreneurial adventures of Frank J. Sprague during the transformative years of the early electrical industry. Over the course of a little less than twenty years, inventor Frank J. Sprague achieved an astonishing series of technological breakthroughs--from pioneering work in self-governing motors to developing the first full-scale operational electric railway system--all while commercializing his inventions and promoting them to financial backers and the public. In Engineering Invention, Frederick Dalzell tells Sprague's story, setting it against the backdrop of (...) one of the most dynamic periods in the history of technology. In a burst of innovation during these years, Sprague and his contemporaries--Thomas Edison, Nicolas Tesla, Elmer Sperry, George Westinghouse, and others--transformed the technologies of electricity and reshaped modern life. After working briefly for Edison, Sprague started the Sprague Electric Railway and Motor Company; designed and built an electric railroad system for Richmond, Virginia; sold his company to Edison and went into the field of electric elevators; almost accidentally discovered a multiple-control system that could equip electric train systems for mass transit; started a third company to commercialize this; then sold this company to Edison and retired. Throughout his career, Dalzell tells us, Sprague framed technology as invention, cast himself as hero, and staged his technologies as dramas. He toiled against the odds, scraped together resources to found companies, bet those companies on technical feats--and pulled it off, multiple times. The idea of the "heroic inventor" is not, of course, the only way to frame the history of technology. Nevertheless, as Dalzell shows, Sprague, Edison, and others crafted the role consciously and actively, using it to generate vital impetus behind the process of innovation. (shrink)

Nikola Tesla (1856–1943) is surely one of the more remarkable figures in the story of global electrification. Rivalling Thomas Edison for the title of chief Wizard, both in his own time and ours, almost every invention of modern life has at some point been attributed to Tesla: from the communications media of telephone, fax, radio, and television, through the military utilities of radar and remote-control weapons, and (most plausibly) the systems of alternate current generation and transmission that power our world. (...) And yet Tesla died impoverished and alone in a New York hotel room with his greatest plans for wireless power transmission abandoned and derided, if they were remembered at all. Tesla’s image as something of a martyr to an ungrateful world has indeed generated a cult following in recent decades, doubtless fired in part by the Serbian nationalism that has justly helped raise the profile of Albert Einstein’s first wife, Mileva Marić (e.g. M. Popović, In Albert’s Shadow: The L .. (shrink)

This paper is a discussion of Michael Thau's interesting critique in Chapter 2 of Consciousness and Cognition, Oxford: Oxford University Press, 2002, of the common view that beliefs are internal states.

W. E. B. Du Bois was one of the most profound and influential African-American intellectuals of the twentieth century. This volume addresses the complexities of Du Bois' legacy, showing how his work gets to the heart of today's theorizing about the color line.

Like their predecessors throughout the late nineteenth and twentieth centuries, popes John Paul II and Benedict XVI have emphasized the importance of philosophy in the Catholic intellectual tradition. In his encyclical _Fides et ratio _, John Paul II called on philosophers “to have the courage to recover, in the flow of an enduringly valid philosophical tradition, the range of authentic wisdom and truth.” Where the late pope spoke of an “enduringly valid tradition,” Jacques Maritain and other Thomists often have referred (...) to the “perennial tradition” or to “perennial philosophy.” __Words of Wisdom__ responds to John Paul's call for the development of this tradition with a much-needed dictionary of terms. As a resource for students in colleges, universities, and seminaries, as well as for teachers of the perennial tradition and interested general readers, __Words of Wisdom __occupies a unique place. It offers precise, yet clear and understandable accounts of well over a thousand key philosophical terms, richly cross-referenced. It also explains significant terms from other philosophical movements with which Thomism has engaged—either through debate or through judicious and creative incorporation. Moreover, it identifies a number of theological and doctrinal expressions to which perennial philosophy has contributed. Finally, it provides a comprehensive bibliography of works by Aquinas in English, expositions and discussions of perennial themes, and representative examples from the writings of all philosophers and theologians mentioned in dictionary entries. “A good dictionary is a great thing. In over 1,000 entries, __Words of Wisdom __manages to be concise, as it must be, and complete where it should be. Its notes on usage by contemporary scholars I find particularly helpful. Students and teachers alike will be grateful to Dr. Carlson for taking up the challenge of John Paul II to appreciate and illuminate the ‘great tradition of philosophy.’” —_David Ruel Foster, Athenaeum of Ohio _.

A work of contemporary Christian political thought, this volume addresses the crisis of modern democracy evident in the decline of the institutions of civil society and their theoretical justification. Drawing upon a rich store of social and political reflection found in the Catholic and Neo-Calvinist traditions, the essays mount a robust defense of the irreducible identity and value of the social institutions_family, neighborhood, church, civic association_that serve as the connective tissue of a political community.

Block's cases of superblindsight, the pneumatic drill, and the Sperling experiments do not show that P-consciousness and Aconsciousness can come apart. On certain tendentious but not implausible construals of the concepts of P- and A-consciousness, they refer to the same psychological phenomenon.

Results: We analyzed 1,402 surveys and 15 in-depth interviews. Many (32%) CL participants reported greater difficulty refilling medications and a minority (14%) reported greater difficulty accessing HIV care during the pandemic. Most (99%) Opt4Mamas participants reported no difficulty refilling medications or accessing HIV/pregnancy care. Among the CL participants, older women were less likely (aOR = 0.95, 95% CI: 0.92–0.98) and women with more children were more likely (aOR = 1.13, 95% CI: 1.00–1.28) to report difficulty refilling medications. Only 2% of (...) CL participants reported greater difficulty managing FP and most (95%) reported no change in likelihood of using FP or desire to get pregnant. Qualitative analysis revealed three major themes: (1) adverse organizational/economic implications of the pandemic, (2) increased importance of pregnancy prevention during the pandemic, and (3) fear of contracting COVID-19.

argues that, by failing to respect the connection between the conjugal act and procreation, in vitro fertilization – even in the homologous or "simple case", where both gametes come from a married couple and the resulting embryo is transferred to the wife – shows itself to be morally unacceptable. On the other hand, the document refers approvingly to other technological interventions which "facilitate" or "assist" the conjugal act in achieving its objective. Although none of the latter interventions are mentioned by (...) name, the recently developed gamete intrafallopian transfer (GIFT) and certain associated techniques have found favor with many orthodox Roman Catholic thinkers, as well with some church authorities. The present article explores this situation in the Catholic moral tradition, and offers reasons for believing that, given relevantly similar conditions, if GIFT is morally acceptable so also is homologous IVF-ET.

Toward A Sociological Imagination builds on the ideas C. Wright Mills expressed in The Sociological Imagination for an approach to the scientific method broad enough to open up to the full range of knowledge within the sociology discipline. In this book, nine sociologists and one philosopher provide detailed tests of the utility of the approach within diverse substantive sociological areas.
