While I agree in general with Stevan Harnad's symbol grounding proposal, I do not believe "transduction" (or "analog process") PER SE is useful in distinguishing between what might best be described as different "degrees" of grounding and, hence, for determining whether a particular system might be capable of cognition. By 'degrees of grounding' I mean whether the effects of grounding go "all the way through" or not. Why is transduction limited in this regard? Because transduction is a physical process which (...) does not speak to the issue of representation, and, therefore, does not explain HOW the informational aspects of signals impinging on sensory surfaces become embodied as symbols or HOW those symbols subsequently cause behavior, both of which, I believe, are important to grounding and to a system's cognitive capacity. Immunity to Searle's Chinese Room (CR) argument does not ensure that a particular system is cognitive, and whether or not a particular degree of groundedness enables a system to pass the Total Turing Test (TTT) may never be determined.

Top-down dynamical models of cognitive processes, such as the one presented by Thelen et al., are important pieces in understanding the development of cognitive abilities in humans and biological organisms. Unlike standard symbolic computational approaches to cognition, such dynamical models offer the hope that they can be connected with more bottom-up, neurologically inspired dynamical models to provide a complete view of cognition at all levels. We raise some questions about the details of their simulation and about potential limitations of (...) top-down dynamical models. (shrink)
In an effort to uncover fundamental differences between computers and brains, this paper identifies computation with a particular kind of physical process, in contrast to interpreting the behaviors of physical systems as one or more abstract computations. That is, whether or not a system is computing depends on how those aspects of the system we consider to be informational physically cause change rather than on our capacity to describe its behaviors in computational terms. A physical framework based on the notion (...) of causal mechanism is used to distinguish different kinds of information processing in a physically-principled way; each information processing type is associated with a particular causal mechanism. The causal mechanism associated with computation is pattern matching, which isphysically defined as the fitting of physical structures such that they cause a simple change. It is argued that information processing in the brain is based on a causal mechanism different than pattern matching so defined, implying that brains do not compute, at least not in the physical sense that digital computers do. This causal difference may also mean that computers cannot have mental states. (shrink)
This paper reports original data on contentious challenges, especially protests, focused on human rights in seven Latin American countries from 1981 to 1995. An analysis reveals that human rights contentious challenges are most prevalent where human rights abuses are worse and authoritarianism is present and in countries that are more urbanized. However, the incidence of such human rights contentious challenges is not related to the number of human rights organizations (HROs) in the country. Results also suggest two different types of (...) human rights contention. National human rights movements, present in Argentina and Guatemala, involved HROs and demanded improvements in the national human rights situation. The other form is ancillary human rights protest, in which human rights challenges are led by a variety of groups, focus on repression particular to the groups involved and are either short-lived or part of a more general wave of opposition. This form of contention was more prevalent in Brazil, Chile, Mexico, Nicaragua, and Venezuela. (shrink)
The notion of superhigh computably enumerable (c.e.) degrees was first introduced by (Mohrherr in Z Math Logik Grundlag Math 32: 5–12, 1986) where she proved the existence of incomplete superhigh c.e. degrees, and high, but not superhigh, c.e. degrees. Recent research shows that the notion of superhighness is closely related to algorithmic randomness and effective measure theory. Jockusch and Mohrherr proved in (Proc Amer Math Soc 94:123–128, 1985) that the diamond lattice can be embedded into the c.e. tt-degrees preserving 0 (...) and 1 and that the two atoms can be low. In this paper, we prove that the two atoms in such embeddings can also be superhigh. (shrink)
Estudos recentes vêm revisando a composição da literatura que, ao longo do século XVIII serviu como base às ciências em território britânico. Segundo esses estudos, os seiscentistas de fala inglesa dedicaram-se a duas linhagens de texto, originadas em concepções de ciência muito distintas. Uma dessas linhagens tinha como fonte principal a antiga “literatura do segredo” que incluía desde velhos e sigilosos manuais de ofício até os milenares e proibidos tratados de hermética, literatura antes reservada a poucos. Diferente dessa, a outra (...) ]inhagem de textos surgia como um direto da proposta baconiana para a nova ciência: um saber elaborado por muitos e ao alcance de todos. Exemplos conhecidos dessa linhagem são os livros de divulgação utilizados pelos comenianos ingleses ou mesmo os relatórios, atas e memórias das sociedades científicas, geradores dos primeiros embriões de periódicos dedicados às ciências. Todavia, sob essa aparente contraposição das duas linhagens, há indícios de um profícuo diálogo - expresso sobretudo na correspondência e diários pensadores da época. (shrink)
This paper presents a comprehensive study of Robert Boyle's writings on seminal principles or seeds. It examines the role of seeds in Boyle's account of creation, the generation of plants and animals, spontaneous generation, the generation of minerals and disease. By an examination of all of Boyle's major extant discussions of seeds it is argued that there were discernible changes in Boyle's views over time. As the years progressed Boyle became more sceptical about the role (...) of seminal principles in the generation of minerals and he came to reject the spontaneous generation of insects and animals from putrefying matter. It is also argued that Boyle's notion of a generative or 'plastick' principle creates a tension within his mechanical philosophy. He appeals to a plastick power in order to explain those phenomena of generation that are beyond the explanatory resources of the corpuscular hypothesis. However, when pressed to explain the nature of this power he either hints, somewhat paradoxically, that it too can be explained mechanically or admits his nescience. (shrink)
Franklin's underrating the importance of the time-of-flight measurements contradicts Segrè's account of the experiment in two journals and Chamberlain's Nobel Prize acceptance speech. Franklin further fails to understand that Segrè's velocity selector method of determining antiproton and proton mass also depends upon measuring the S1-to-S2 flight distance. Franklin's conclusion that there is no evidence that the Segrè mesons are traveling faster than light is based on a faulty premise about the average antiproton velocity.
The essays in this volume critically analyze and revitalize agrarian philosophy by tracing its evolution in the classical American philosophy of key figures such as Franklin, Jefferson, Emerson, Thoreau, Dewey, and Royce.
Cosmetic surgery is a fast-growing medical practice. In 1997 surgeons in the United States performed the four most common cosmetic procedures443,728 times, an increase of 150% over the comparable total for 1992. Estimated total expenditures for cosmetic surgery range from $1 to $2 billion. As managed care cuts into physicians' income and autonomy, cosmetic surgery, which is not covered by health insurance, offers a financially attractive medical specialty.
Two essays relating Thomas and Whitehead have recently appeared. Coming To Be by James W. Felt, S.J., modifies Thomas by replacing his substantial form with Whitehead’s notion of subjective aim, the essencein-the-making introduced by God to guide the occasion’s act of coming into being. Felt also substitutes subjective aim for matter as the means of individuation. This is one of Whitehead’s individuating principles, although a case can be made that matter (the multiplicity of past actualities as proximate matter) is another. (...) “God and Creativity” by Stephen T. Franklin develops a reconciliation of these two ultimates by conceiving of God as the source of creativity, and seeing creativity in terms of the Thomistic esse. In my reflections on this project I explore four alternativeswith respect to the source of creativity: (a) creativity as derived from the past; (b) creativity as inherent in the present; (c) God as the source of transitional creativity (Franklin); (d) God as the source of concrescent creativity (Ford). The last two differ with respect to being’s relation to becoming. Does being undergird becoming, or does becoming bring about being, such that apart from it there would be no being? Our theory of creation depends upon this question. (shrink)
A Martin-Löf random sequence is an infinite binary sequence with the property that every initial segment $\sigma$ has prefix-free Kolmogorov complexity $K(\sigma)$ at least $|\sigma| - c$, for some constant $c \in \omega$. Informally, initial segments of Martin-Löf randoms are highly complex in the sense that they are not compressible by more than a constant number of bits. However, all Martin-Löf randoms necessarily have contiguous substrings of arbitrarily low complexity. If we demand that all substrings of a sequence be uniformly (...) complex, then we arrive at the notion of shift-complex sequences. In this paper, we collect some of the existing results on these sequences and contribute two new ones. Rumyantsev showed that the measure of oracles that compute shift-complex sequences is zero. We strengthen this result by proving that the Martin-Löf random sequences that do not compute shift-complex sequences are exactly the incomplete ones, in other words, the ones that do not compute the halting problem. In order to do so, we make use of the characterization by Franklin and Ng of the class of incomplete Martin-Löf randoms via a notion of randomness called difference randomness. Turning to the power of shift-complex sequences as oracles, we show that there are shift-complex sequences that do not compute Martin-Löf random (or even Kurtz random) sequences. (shrink)
T. C. Boyle’s A Friend of the Earth (2001), tells the story of Tyrone Tierwater, a one time monkeywrencher and environmental avenger for “E. F.!” (Earth Forever!) who we first meet in 2025 in his mid-seventies. Tierwater is now working for a character based on Michael Jackson, who in his semi-retirement has employed the elder eco-warrior to help save some of the last remnants of a few dying species – warthogs, peccaries, hyenas, jackals, lions and what is likely the (...) last Patagoninan fox. The not too distant environmental future painted by Boyle is a disaster. Global warming has finally caught up to us with a vengeance and even the secure shores of the U.S. are wracked by unmitigated cycles of flooding and drought seriously degrading most semblances of life as we know it. To be sure, though, people, and some versions of progress, go on. While most affordable food and drink is limited to some combination of catfish and sake (very little else having survived decades of disastrous weather and a series of crop blights), and there are constant threats of new strains of life-threatening and highly contagious diseases, suburban development continues and new humans come into existence with the promise, at least in the developed world, of longer life spans. But Boyle does not give us anything like the overly optimistic views expressed by some conservative columnists who dismiss the need for global climate treaties; this is not an environmental future that is only felt with difficulty in the underdeveloped south requiring simpler economic readjustments for Americans without a substantial shift in lifestyle.

Ethics position theory (EPT) maintains that individuals’ personal moral philosophies influence their judgments, actions, and emotions in ethically intense situations. The theory, when describing these moral viewpoints, stresses two dimensions: idealism (concern for benign outcomes) and relativism (skepticism with regards to inviolate moral principles). Variations in idealism and relativism across countries were examined via a meta-analysis of studies that assessed these two aspects of moral thought using the ethics position questionnaire (EPQ; Forsyth, Journal of Personality and Social Psychology 39 , (...) 175–184, 1980). This review identified 139 samples drawn from 29 different countries, for a total sample of 30,230 respondents, and concluded that (a) levels of idealism and relativism vary across regions of the world in predictable ways; (b) an exceptionist ethic is more common in Western countries, subjectivism and situationism in Eastern countries, and absolutism and situationism in Middle Eastern countries; and (c) a nation’s ethics position predicted that country’s location on previously documented cultural dimensions, such as individualism and avoidance of uncertainty (Hofstede, Culture’s Consequences: International Differences in Work-Related Values , 1980). Limitations in these methods and concerns about the validity of these cross-cultural conclusions are noted, as are suggestions for further research using the EPQ. (shrink)
This paper features a detailed philosophical classification of the four types of deists that Samuel Clarke presents in the second series of the Boyle Lectures for promoting Christianity (1705). In the course of this paper I determine, for each type of deist, the truth values of twelve important propositions, and I show that these four types of deists may be categorized as (1) ‘no-providence’, (2) ‘physical-laws-providence’, (3) ‘moral-but-no-afterlife’, and (4) ‘moral-and-afterlife’. Using an accompanying table of propositions as a visualization (...) tool, I also show that Clarke's account of these four types of deists may be thought of as ‘progressively Christian’: for each type of deist, from lower-number deists to higher-number deists, there is an increasing number of truth values that are Christian-like.
