This article describes research to build an embodied conversational agent as an interface to a question-and-answer system about a National Science Foundation program. We call this ECA the LifeLike Avatar, and it can interact with its users in spoken natural language to answer general as well as specific questions about specific topics. In an idealized case, the LifeLike Avatar could conceivably provide a user with a level of interaction such that he or she would not be certain as to whether (...) he or she is talking to the actual person via video teleconference. This could be considered a extended version of the seminal Turing test. Although passing such a test is still far off, our work moves the science in that direction. The Uncanny Valley notwithstanding, applications of such lifelike interfaces could include those where specific instructors/caregivers could be represented as stand-ins for the actual person in situations where personal representation is important. Possible areas that come to mind that might benefit from these lifelike ECAs include health-care support for elderly/disabled patients in extended home care, education/training, and knowledge preservation. Another more personal application would be to posthumously preserve elements of the persona of a loved one by family members. We apply this approach to a Q/a system for knowledge preservation and dissemination, where the specific individual who had this knowledge was to retire from the US National Science Foundation. The system is described in detail, and evaluations were performed to determine how well the system was perceived by users. (shrink)

Metaphysics, formerly the queen of science, fell into oblivion under the onslaught of empiricism and positivism and its very possibllity came to be denied. Professor Elders traces the history of this process and shows how St. Thomas innovated in determining both the subject of metaphysics and the manner in which one enters this science, particularly in the framework of his Aristotle commentaries. The work then considers being and its properties, its divisions into being in act and being in potency, into (...) the act of being essence, and into substance and the accidents. Finally the causes of being are considered. The work also introduces and surveys the extensive literature of Thomas interpretation of the past 50 years. (shrink)

Leon J. Goldstein critically examines the philosophical role of concepts and concept formation in the social sciences. The book undertakes a study of concept formation and change by looking at four critical terms in anthropology , politics , and sociology.

A collection of papers dealing with history as a way of knowing, not a mode of discourse.

This book introduces Robert Corrington’s “ecstatic naturalism,” a new perspective in understanding “sacred” nature and naturalism, and explores what can be done with this philosophical thought. This is an excellent resource for scholars of Continental philosophy, philosophy of religion, and American pragmatism.

"An adequate theory of culture," says David Bidney in Theoretical Anthropology, "must explain the origin of culture and its intrinsic relations to the psychobiological nature of man. To insist upon the self-sufficiency and autonomy of culture, as if culture were a closed system requiring only historical explanations in terms of other cultural phenomena, is not to explain culture, but to leave its origin a mystery or an accident of time". Earlier, on the same page, he writes, "Culture is not an (...) 'objective construct' whose existence is independent of man; it depends, rather, upon man's innate equipment and biological inheritance." These formulations reflect both his own interests and his misconstrual of the intentions of other anthropologists. One would suspect from the way he puts it that it was quite common for anthropologists to talk about a self-subsistent entity, culture, really existing independent of human beings. This is simply not the case, but the reasons for his view must be made apparent. (shrink)

Though many would prefer to have nothing to do with teleological explanations, it is evident that the writings of biologists and social scientists abound with them, and it is worth paying attention to the conditions under which they may be made responsibly. It emerges that responsible teleological statements would have to be made about instances of recurrent structures having specifiable characteristics, a situation which is patently the case for biology but still unsettled in, say, anthropology. In the final part of (...) the paper it is shown that satisfying this condition provides a basis for formulating general laws of the more orthodox kind. (shrink)

Finally the causes of being are considered. The work also introduces and surveys the extensive literature of Thomas interpretation of the past 50 years.

The first part of the paper distinguishes between a real past which has nothing to do with historical events and an historical past made up of hypothetical events introduced for the purpose of explaining historical evidence. Attention is next paid to those so-called ancillary historical disciplines which study historical evidence, and it is noted that the historical event is brought in to explain the particular constellation of different kinds of historical evidence which are judged to belong together. The problem of (...) explaining events is then taken up, and an attempt is made to defend the view that such explanation must presuppose general laws. And this is followed by a discussion, partly speculative, of social-historical laws. The final section of the paper tries to argue that the subjective intentions of individuals are irrelevant to historical explanation. (shrink)

The Physics is a most remarkable work, and profoundly influenced Medieval Philosophers. Thomas Aquinas wrote a detailed, impressive commentary. This essay studies in particular the composition of the Physics as Thomas saw it, his thorough study of Aristotle’s way of arguing and the important distinction he made between disputative arguments, which are only partially true, and arguments which determine the truth. Aristotle frequently uses proofs which are wrong when one considers the proper nature of bodies, but possible considering their common (...) nature. Thomas accepts proofs in the field of physics but discards those related to a certain mathematization of nature. Aristotle holds the unlimited possibility of movements becoming faster or slower, but according to Aquinas he is considering things in general : when we consider specific bodies there is a fastest movement. Thomas speaks of a way of reading a text which is according the intention of Aristotle, and proposes an understanding of particular texts based on the general doctrine of the Stagirite. Sometimes he goes beyond the text, as when defending the unity of time as dependent on the unity of the First Mover. The essay shows that in the commentary a coherent philosophy of nature shaping up. In some places Aquinas brings in God’s causality: nature is nothing else but the plan of divine art, placed within things. The study of nature shows that there is a first principle of the whole nature which is above everything, sc. God who gives being to things. (shrink)
