Noam Chomsky and Frances Egan argue that David Marr’s computational theory of vision is not intentional, claiming that the formal scientific theory does not include description of visual content. They also argue that the theory is internalist in the sense of not describing things physically external to the perceiver. They argue that these claims hold for computational theories of vision in general. Beyond theories of vision, they argue that representational content does not figure as a topic within formal computational theories (...) in cognitive science. I demonstrate that Chomsky’s and Egan’s claims about Marr’s theory are false. Marr’s computational theory contains a mathematical theory of visual content, based on empirical psychophysical evidence. It also contains mathematical descriptions of distal physical surfaces and objects, and of their optic projection to the perceiver. Much computational research on vision contains these types of intentional and externalist components within the formal, mathematical, theories. Chomsky’s and Egan’s claims demonstrate inadequate study and understanding of Marr’s work and other research in this area. Computational theories of vision, by containing empirically based mathematical theories of visual content, to this extent present naturalizations of semantics. (shrink)

Comparing technical notions of communication and computation leads to a surprising result, these notions are often not conceptually distinguishable. This paper will show how the two notions may fail to be clearly distinguished from each other. The most famous models of computation and communication, Turing Machines and (Shannon-style) information sources, are considered. The most significant difference lies in the types of state-transitions allowed in each sort of model. This difference does not correspond to the difference that would be expected after (...) considering the ordinary usage of these terms. However, the natural usage of these terms are surprisingly difficult to distinguish from each other. The two notions may be kept distinct if computation is limited to actions within a system and communications is an interaction between a system and its environment. Unfortunately, this decision requires giving up much of the nuance associated with natural language versions of these important terms. (shrink)

Psience Fiction: The Paranormal in Science Fiction Literature is a book that really needed to be written. In an abundance of hubris I once played with the idea myself (and I was probably not alone in the thought). But now Damien Broderick has done it, and much better than I could have even approximated. Given his background as a science fiction literary critic and author himself, no other writer could be better-equipped. Psience Fiction is exactly the right title to (...) encapsulate Broderick’s chosen topic. As he notes in one passage, his purpose here is to explore “the varied representations of the paranormal in science fiction” (p.68)–though by paranormal he refers neither to ghosts nor mediumship nor UFO-related phenomena, but strictly to “paranormal” as it relates to putative mental powers that transcend the scientifically-presumed, neuro-physical limits of our minds and brains. He refines that still further in noting that what he wants to consider is “...the give and take between the science fiction paranormal and the real-world kind, tested and tallied by psi researchers” (p.5). This book is probably most easily described as a book of book reviews (though a few relevant short stories are also considered). Authors covered run the gamut from Olaf Stapledon, E.E. “Doc” Smith, James Blish and Theodore Sturgeon to Zenna Henderson, John Wyndham, Robert Heinlein, Ann McCaffery, Octavia Butler, and John Brunner, plus many more. For a literary work to be included, it must incorporate some aspect of psi as an integral plot element; a mere mention of extrasensory perception or psychokinesis does not suffice. (shrink)

MIT Press, 1999 Review by Paul Bohan Broderick, Ph.D. on May 26th 2002 Volume: 6, Number: 21.

This self-contained treatise, originally published in 1947 by Holt, Rinehart and Winston, examines fundamental features of nature in order to lay the groundwork for providing a solution to the major problems of ethics.

Educational aspirations under an ideal state and educational expectations based on reality have an important impact on children’s academic development, but distinct differences between them exist. On the basis of distinguishing the differences between the two, using the national data of Tsinghua University’s China Urbanization and Child Development Survey, this article endeavors to explore the inequality of educational aspirations and expectations from the perspective of class and urban-rural areas, and lay out the influencing factors of educational aspirations, expectations, and the (...) difference between them. It is found that Chinese parents generally have high aspirations for their children’s education. There is no distinct class difference in “high hopes for children’s bright future.” However, in the sense of educational expectations, there are distinct class differences, which are deeply rooted in socioeconomic status and closely related to education level, family type, family structure, and family economic status, as well as children’s academic performance.

In the decades after the Civil War, Southerners wrote and published their own history textbooks for secondary schools. These “mint julep textbooks,” as the Southern all-white editions were called by the 1960s, reinforced a Lost Cause narrative of the war for Southern audiences while competing with Northern versions of events. In this study, we employ both historical narrative and content analysis of six textbooks’ portrayals of John Brown, John Wilkes Booth, and Nathan Bedford Forrest. The textbooks that are compared– three (...) Southern and three Northern – were written from the 1870s through the 1910s. While subtle but important differences emerge between the Northern and Southern depiction of these three figures, an even more important trend developed when analyzing change over time. In this article we conclude that, as time progressed, Southern versions of events increasingly impacted Northern textbooks. By the 1930s, the mint julep version of these three figures became the national consensus, as reflected in the work of historian David Saville Muzzey. This consensus around events like the raid at Harpers Ferry, the assassination of Lincoln, and the massacre at Fort Pillow lasted for much of the 20th century. By the early 20th century, Northerners appeased Southern interests in the writing of history textbooks. (shrink)

The options in a decision problem generally have outcomes with common features. Putting aside the common features simplifies deliberations, but the simplification requires a philosophical justification that this book provides.

In the first part of this paper some general theses concerning the difference between logic and mathematics are defended. In the second part four different views for a possible demarcation between logic and mathematics are stated.

An agent often does not have precise probabilities or utilities to guide resolution of a decision problem. I advance a principle of rationality for making decisions in such cases. To begin, I represent the doxastic and conative state of an agent with a set of pairs of a probability assignment and a utility assignment. Then I support a decision principle that allows any act that maximizes expected utility according to some pair of assignments in the set. Assuming that computation of (...) an option's expected utility uses comprehensive possible outcomes that include the option's risk, no consideration supports a stricter requirement. (shrink)

Schelling und Hegel benutzen in ihren philosophischen Texten mathematische und naturwissenschaftliche Modelle wie Unendlichkeit oder Gleichgewicht. Die Strukturen dieser Begriffe liefern einen Massstab fur den Vergleich der Positionen Schellings und Hegels, der fur Schellings Identitatsphilosophie und Hegels erste Jenaer Schriften durchgefuhrt wird. Als wichtigstes Resultat kann eine grundlegende Differenz zwischen beiden Positionen bereits um 1801 nachgewiesen und gezeigt werden, dass diese auf einer unterschiedlichen Auffassung der Rolle des Absoluten beruht.

Die MISCELLANEA MEDIAEVALIA präsentieren seit ihrer Gründung durch Paul Wilpert im Jahre 1962 Arbeiten des Thomas-Instituts der Universität zu Köln. Das Kernstück der Publikationsreihe bilden die Akten der im zweijährigen Rhythmus stattfindenden Kölner Mediaevistentagungen, die vor über 50 Jahren von Josef Koch, dem Gründungsdirektor des Instituts, ins Leben gerufen wurden. Der interdisziplinäre Charakter dieser Kongresse prägt auch die Tagungsakten: Die MISCELLANEA MEDIAEVALIA versammeln Beiträge aus allen mediävistischen Disziplinen - die mittelalterliche Geschichte, die Philosophie, die Theologie sowie die Kunst- und (...)

The first book-length study of a leading tenth-century Ismaili theoretician Abu Ya'qub al-Sijistani.

This introductory chapter provides an overview of the content discussed in the subsequent chapters of the book. Machine or artificial intelligence (AI), might well have the ability to understand, modify, and improve its own source code, carrying it by great leaps into domains of ability that unaided flesh can never hope to reach. AI uses engineered electronic or photonic neural nets operating a million times faster. Uploading need not imply a world of bloated grubs lying in the dark with their (...) brains wired to spreadsheets and simulated worlds. The initial goal of uploaders would be to emulate and enhance the brain, and that requires rich connections to external reality. The artificial system is not merely simulating but actually emulating or replicating the relevant functioning of a human brain. The book shows enthusiasm about the prospects of machine intelligence and mind uploading, and expresses skepticism or concern. (shrink)

Everyone has mixed feelings about the future, especially about the many powerful technologies changing our world – and us as well. Trash TV excites us with visions of bionic limbs for the helpless, robot puppies craving attention but never messing the carpet, painless laser dentistry, clones, and weird genetic hybrids.

The present article shows that there are consistent and decidable manyvalued systems of propositional logic which satisfy two or all the three criteria for non-trivial inconsistent theories by da Costa . The weaker one of these paraconsistent system is also able to avoid a series of paradoxes which come up when classical logic is applied to empirical sciences. These paraconsistent systems are based on a 6-valued system of propositional logic for avoiding difficulties in several domains of empirical science ).

The centrality of death rituals has in anthropologically informed studies of Buddhism been little documented. The current volume brings together a range of perspectives on Buddhist death rituals including ethnographic, textual, historical and theoretically informed accounts, and presents the diversity of the Buddhist funeral cultures of mainland Southeast Asia and China. It arises out of the University of Bristol's Centre for Buddhist Studies research project Buddhist Death Rituals in Southeast Asia and China, funded by the United Kingdom's Arts and Humanities (...) Research Council. This project involved extensive new research in Thailand, Laos and China. Other items from that project included several public exhibitions, extensive stills photographs, and several video films. The project-team produced two 30 minutes films on the ghost festival in Laos and China, one on urban funerals in Chiang Mai (Thailand) and several shorter clips dealing with funeral cultures in Laos, Thailand and China. Most of this material (and an extensive bibliography on the topic) is available free of charge from the project website located at the webpage of the Department of Theology and Religious Studies (Centre for Buddhist Studies) at the University of Bristol.

This article contends that the evolution toward interdisciplinary collaboration that we are witnessing in the sciences must also occur in the humanities to ensure their very survival. That is, humanists must be open to working with scientists and social scientists interested in similar research questions and vice versa. Digital humanities is a positive first step. Complexity science should be the next step. Even though much of the ground-breaking work in complexity science has been done in the natural sciences and mathematics, (...) it can, if critically adapted, provide the needed metaphor for a broad integration of disciplines, humanistic and otherwise. Given its almost a-disciplinary nature, a complexity approach to the research problems in the humanities necessarily breaks down silos. Moreover, it can restore and reframe the seamless intellectual fabric sought by researchers before the atomization of the various disciplines in the nineteenthcentury academy. (shrink)

Social studies teachers are frequently athletic coaches who are often criticized for prioritizing coaching over teaching. The purpose of this study is to investigate the experiences of preservice social studies teachers regarding the relationship between coaching and teaching with respect to hiring in middle and secondary schools. The researchers employed phenomenological research methods to investigate the hiring experiences of social studies teacher candidates. Survey and interview data were collected from social studies teacher candidates at the three largest universities in a (...) southeastern state. Results illuminate a pervasive coaching contingency that many social studies teacher candidates face. Social studies teacher candidates perceived that willingness to coach a sport is the most important factor, other than teaching, to be hired to teach—particularly at the high school level. (shrink)

Evidence found in The New York Times from 1939 to 1945 and corroborating sources are used to demonstrate the impact of the Second World War on the progressive educational movement. We posit that December 7, 1941 initiated the waning of the progressive education movement in the secondary social studies curriculum. Progressive education emphasized a child-centered, experiential curriculum, an issues-centered approach to learning, and a critical analysis of society. Our findings indicate that the educational climate during the Second World War initiated (...) a shift from questioning American institutions to celebrating them. Education became more centralized and many educational organizations were mobilized to support the war effort. Specifically, the secondary social studies curriculum became one of several propaganda vehicles in support of the war. In addition, colleges and universities became training grounds for teachers, defense workers, and soldiers. A war on the home front ensued. The progressive secondary social studies curriculum itself was viewed as placing the nation at risk. While other factors such as the Back-to-Basics movement and the Cold War contributed to the waning of the secondary progressive educational movement, World War Two (WWII) set the decline in motion.
