I argue that naturalistic pictures provide a guide and a justification for our concept of colour. The crucial relation between pictures and colours is to be brought out, not by reference to the ‘internal’ relations between colours (for example, what differentiates green from red), but by considering how colours are differentiated from the wider range of visually discriminable qualities. Naturalistic pictures effect such a differentiation by simulating colour-like qualities such as gold, amber, and blond, while requiring nothing beyond the three-dimensional (...) manifold of colour space. The seeming simplicity and salience of colour in our visual experience should be recognized as depending on our familiarity with this reductive power of naturalistic pictures. While some sense of these issues has been given expression by many thinkers, the idea is significantly articulated in remarks of Wittgenstein's that were prompted by his reading of a letter the painter Runge wrote to Goethe.

Church's thesis, that all reasonable definitions of “computability” are equivalent, is not usually thought of in terms of computability by acontinuouscomputer, of which the general-purpose analog computer (GPAC) is a prototype. Here we prove, under a hypothesis of determinism, that the analytic outputs of aC∞GPAC are computable by a digital computer.In [POE, Theorems 5, 6, 7, and 8], Pour-El obtained some related results. (The proof there of Theorem 7 depends on her Theorem 2, for which the proof in [POE] is (...) incorrect, but for which a correct proof is given in [LIR]. Also, the proof in [POE] of Theorem 8 depends on the unproved assertion that a solution of an algebraic differential equation must be analytic on an open subset of its domain. However, this assertion was later proved in [BRR].) As in [POE], we reduce the problem to a problem about solutions of certain systems of algebraic differential equations (ADE's). If such a system is nonsingular (i.e. if the “separant” does not vanish along the given solution), then the argument is very easy (see [VSD] for an even simpler situation), so that the essential difficulties arise fromsingularsystems. Our main tools in handling these difficulties are drawn from the excellent (and difficult) paper [DEL] by Denef and Lipshitz. The author especially wants to thank Leonard Lipshitz for his kind help in the preparation of the present paper.We emphasize here that our proof of the simulation result applies only to the GPAC as described below. The GPAC's form a natural subclass of the class of all analog computers, and are based on certain idealized components (“black boxes”), mostly associated with the technology of past decades. One can easily envisage other kinds of black boxes of an input-output character that would lead to different kinds of analog computers. (For example, one could incorporate delays, or spatial integrators in addition to the present temporal integrators, etc.) Whether digital simulation is possible for these “extended” analog computers poses a rich and challenging set of research questions.

SummaryIt has been argued that clinical medicine should be regarded as a relatively autonomous science. While it draws upon other sciences which variously contribute to medical knowledge, it is not just an “application” of any of these, alone or in combination. Its contributions to medical knowledge are made within the context of patient care (the term “clinical medicine” is used here to emphasize this matter). It is distinct from other sciences in its domain of inquiry and its approach to this (...) domain, studying relationships between events and processes of many kinds and levels as they occur in the human organism. To the fullest extent possible (and to an extent not possible elsewhere) these relationships are investigated as they occur within the living organism. Arguments providing logical justification for this approach have been offered. The practical justification of its approach, and of clinical medicine itself, rests in its accomplishments. Various possible objections to the scientific status of clinical medicine have been discussed and found lacking in force. I have no doubt that there might be other objections. However, these would also, I believe, be found on examination to result from too restrictive definitions of “science,” unacceptable in their exclusion also of other recognized sciences, or from lack of familiarity with modern clinical medicine.

The academic literature commonly exposes large components of informal economies housed in developed countries as nefarious systems designed to help people evade taxes or carry on other illegal activities. However, our community-based participatory action study uncovered a significant element of a social and economic system that was largely undocumented, but was viewed as far more righteous than dishonorable and immoral. Our research involved approximately 375 participants from seven communities spread across a large and sparsely populated geographic region in the northern (...) part of the Canadian province of Saskatchewan. The purpose for the research was to explore how entrepreneurship contributes to the good life, well-being, and prosperity by building social and economic capacity across a rural business ecosystem. We found that an important, yet undocumented part of the business ecosystem was grounded in history, culture, and tradition. When considered through a legitimacy theory lens, this perspective challenges the implication drawn from some of the academic literature that those who participate in informal business systems in developed countries usually do so for immoral reasons that might warrant a legal penalty. Further, we propose that researchers, policy makers, and community development professionals use the term undocumented economy rather than expressions like informal, hidden and underground economy to distinguish components of economic systems based on righteous motivations and activities from those founded on iniquitous practices and non-existent or unofficial record keeping. We begin this article with a definition for the undocumented economy in which we describe why we consider it to be righteous. (shrink)

This investigation sought to find the relationships among multiple dimensions of personality and multiple features of language style. Unlike previous investigations, after controlling for such other moderators as culture and socio-demographics, the current investigation explored those dimensions of naturalistic spoken language that most closely align with communication. In groups of five to eight players, participants from eight international locales completed hour-long competitive games consisting of a series of ostensible missions. Composite measures of quantity, lexical diversity, sentiment, immediacy and negations were (...) measured with an automated tool called SPLICE and with Linguistic Inquiry and Word Count. We also investigated style dynamics over the course of an interaction. We found predictors of extraversion, agreeableness, and neuroticism, but overall fewer significant associations than prior studies, suggesting greater heterogeneity in language style in contexts entailing interactivity, conversation rather than solitary message production, oral rather than written discourse, and groups rather than dyads. Extraverts were found to maintain greater linguistic style consistency over the course of an interaction. The discussion addresses the potential for Type I error when studying the relationship between language and personality. (shrink)

Agrarianism, according to Paul B. Thompson, is an environmental philosophy focused on agriculture and the nurturing of food, fuel, and fiber. Agrarianism hopes to re-establish our fundamental connection to the land, helping us approach a tenable understanding of sustainability. Thompson enlists Albert Borgmann’s notion of “focal practices” to discuss farming and the culture of the table. With this comes a critique of “the device paradigm,” the modern technological way of life that alienates us from quotidian beauty, lifecycles and seasonality, and (...) vital place-based insights embedded in focal practices and obscures how techno-industrial capitalism limits our opportunities for rich, intimate experiences with our biotic communities. In this paper, the author will outline the contours of Thompson’s agrarian philosophy in light of Borgmann’s focal practices, noting the enduring wisdom in this position. But the author will evoke Sylvia Wynter’s critique of the hegemonic techno-industrial order of things to conjure alternative conceptions of decolonial agrarian futures (that will not foreground bucolic settler-colonial farms).

John Dewey and Alasdair MacIntyre are seldom considered philosophically compatible. Yet, both critique contemporary liberalism by focusing on the pervasiveness of atomistic, pecuniary, laissez-faire individualism. I argue that Dewey and MacIntyre have not abandoned individualism as much as reconstructed the concept. Dewey's and MacIntyre's conceptions of human flourishing rely on a nuanced conception of individualism, which I term "collectivistic individualism.".

Atran & Norenzayan (A&N) are correct that religion is an evolutionary by-product, not an adaptation, but they do not go far enough. Once supernatural beliefs are enabled by processes they describe, numerous social-cognitive mechanisms related to attachment, social exchange, coalitional psychology, status and dominance, and kinship are crucial for explaining the specific forms religion takes and individual and cultural differences therein.

This book explores convergences and divergences between process thought and Roman Catholicism. It examines why process philosophy and process theology have had a minimal impact in Roman Catholic circles compared to Protestantism, and investigates avenues of promising engagement between process thought and Roman Catholicism.

Both Watts and Beit-Hallahmi are enthusiastic about attachment theory as an important contribution to the psychology of religion, but they raise very different criticisms regarding other aspects of the book. I respond to Beit-Hallahmi by defending my assertion that a scientific approach to psychology of religion need not lead to the conclusion, nor rest on the premise, that the beliefs under study are ontologically false. I argue further that this "veridicality trap" has deep roots in prevailing, deeply mistaken assumptions about (...) how the mind/brain works, and show how an evolutionary approach clearly exposes such reasoning as fallacious and offers a powerful, alternative perspective on the problem. In response to Watts, I defend evolutionary psychology against the charge that it is not sufficiently empirical, and argue that the computational cognitive approach he prefers should be seen as complementary to an evolutionary approach rather than an alternative to it.

ABSTRACT In “Race, Multiculturalism, and Democracy,” Robert Gooding-Williams offers an insight. He writes: “Our sense of ourselves and of the possibilities existing for us is, to a significant degree, a function of the descriptions we have available to us to conceptualize our intended actions and prospective lives…. ‘Hence if new modes of description come into being, new possibilities of action come into being in consequence.’” In this article, I discuss the philosopher's role in the articulation of new descriptions and thus (...) new possibilities. I argue that potential modes of bold and assertive comportment are conjured when new insurrectionist descriptions are articulated within oppressed populations. To bring this to a higher resolution, I discuss the pervasiveness of dialectical conflict, the need to creatively reorient the descriptions of oppressed groups toward liberation, and the need for more than one prescriptive mode of social amelioration.

This paper offers a new concept of the firm that aims at balancing the corporate economic, social, and environmental responsibilities and goes beyond the stakeholder approach. It intends to provide a conceptual and operationalizable basis to fairly assess corporate conduct from both inside and outside the companies. To a large extent these different responsibilities may overlap and reinforce each other. However, if they conflict, they should be clearly evaluated for their own sake and in terms of wealth creation. Only then (...) can a balanced approach be realized. Section 1 briefly discusses some general aspects of the relationship between concepts and measurement. In Section 2, a concept of the firm is developed that is based on the notion of responsibility and balances economic, social and environmental responsibilities. According to these concepts, different ways of measuring corporate planning and performance are examined in Section 3, followed up by a summary and conclusions. (shrink)

God vs. the Gavel challenges the pervasive assumption that all religious conduct deserves constitutional protection. While religious conduct provides many benefits to society, it is not always benign. The thesis of the book is that anyone who harms another person should be governed by the laws that govern everyone else - and truth be told, religion is capable of great harm. This may not sound like a radical proposition, but it has been under assault since the 1960s. The majority of (...) academics and many religious organizations would construct a fortress around religious conduct that would make it extremely difficult to prosecute child abuse by clergy, medical neglect of children by faith-healers, and other socially unacceptable behaviors. This book intends to change the course of the public debate over religion by bringing to the public's attention the tactics of religious entities to avoid the law and therefore harm others. (shrink)

Traditional navigation visualization utilizes two-dimensional. maps for road guidance or arrow symbols for turn by turn information. While the advantage of map views is supposed to be the inherent understanding of the surroundings, often these schematic line-drawing bird's eye views are rather confusing than helpful because they cannot provide an overview and an appropriate level of detail in an area of interest at the same time, i.e. the user is forced to change between different resolutions. In this paper we describe (...) a 3D visualization system for vehicle navigation that overcomes these shortcomings by providing a realistic and perspective 3D view of the environment. (shrink)

Collating, for the first time, the key writings of Leonard Harris, this volume introduces readers to a leading figure in African-American and liberatory thought. -/- Harris' writings on honor, insurrectionist ethics, tradition, and his work on Alain Locke have established him as a leading figure in critical philosophy. His timely and urgent responses to structural racism and structural violence mark him out as a bold cultural commentator and a deft theoretician. -/- The wealth and depth of Harris' writings are brought (...) to the fore in this collection and the incisive introduction by Lee McBride serves to orient, contextualize, and frame an oeuvre that spans four decades. In his prolegomenon, Harris eschews the classical meaning of “philosophy,” supplanting it with an idiosyncratic conception of philosophy--philosophia nata ex conatu--that features an avowedly value-laden dimension. As well as serving as an introduction to Harris' philosophy, A Philosophy of Struggle provides new insights into how we ought conceptualize philosophy, race, tradition, and insurrection in the 21st century.

Raymond Boisvert and Lisa Heldke begin Philosophers at Table with a simile. Following Mary Midgley, they suggest that philosophy is like plumbing. We post-industrial urbanites and suburbanites rely on plumbing to bring us water and dispose of our waste. We rely on it daily, but we rarely think reflectively about it. In like fashion, we all rely on philosophy; ideas, concepts, values, and guiding principles structure and organize the way we perceive and experience the world. Philosophy lies undetected, out of (...) sight, tucked neatly in the walls and under the floorboards. We typically suffer its dripping faucets, its low water pressure, its slow drain as long as we can because these almost always involve unwieldy... (shrink)

Debate over the curricula of Black colleges and universities dates back to before the turn of the century and involved such noted Black leaders as Booker T. Washington and W.E.B. DuBois. The 1890 Land-Grant Colleges eventually established in 17 southern and border states were created to provide institutions for the teaching of the agricultural and mechanical arts to African-Americans. However, due to their being chronically underfunded and understaffed during the early decades of their existence, they focused mainly on teacher training (...) and to a large extent became state normal schools or teacher colleges for Blacks. I argue that the improvements in public education of southern Blacks at the primary and secondary levels during the 1920s and 1930s induced many graduates of the 1890 institutions to become teachers. At the same time the growing numbers and higher quality of these individuals lead to an increase in the returns to time spent in school and induced increasing numbers of Black parents to send their children to school. During the 1930s expenditures per pupil in Black public schools increased, as did the real wages of Black teachers, while average classroom size fell. At the same time both literacy and school attendance of southern Blacks rose. In no small part these changes were due to 1890 colleges and their students. (shrink)

The origin of marine invertebrate larvae has been an area of controversy in developmental evolution for over a century. Here, we address the question of whether a pelagic “larval” or benthic “adult” morphology originated first in metazoan lineages by testing the hypothesis that particular gene co-option patterns will be associated with the origin of feeding, indirect developing larval forms. Empirical evidence bearing on this hypothesis is derivable from gene expression studies of the sea urchin larval gut of two closely related (...) but differently developing congenerics, Heliocidaris tuberculata (feeding indirect-developing larva) and H. erythrogramma (nonfeeding direct developer), given two subsidiary hypotheses. (1) If larval gut gene expression in H. tuberculata was co-opted from an ancestral adult expression pattern, then the gut expression pattern will remain in adult H. erythrogramma despite its direct development. (2) Genes expressed in the larval gut of H. tuberculata will not have a coordinated expression pattern in H. erythrogramma larvae due to loss of a functional gut. Five structural genes expressed in the invaginating archenteron of H. tuberculata during gastrulation exhibit substantially different expression patterns in H. erythrogramma with only one remaining endoderm specific. Expression of these genes in the adult of H. erythrogramma and larval gut of H. tuberculata, but not in H. erythrogramma larval endoderm, supports the hypothesis that they first played roles in the formation of adult structures and were subsequently recruited into larval ontogeny during the origin and evolution of feeding planktotrophic deuterostome larvae.

We present a derivation of the homogeneous Lorentz transformations that arrives immediately at the general form without the usual specialization in thex direction.

We point out that the acceptance of the relativity principle together with the homogeneity and isotropy of space and the homogeneity of time inevitably leads to the Lorentz spacetime transformation with a universal limiting speed σ. Speculations on possible new four-dimensional symmetries involving a variable “speed of light” such as that proposed by Hsu must therefore be dismissed on such a basis alone. In this paper we draw attention to some logical inconsistencies in Hsu's attempt at establishing a new space-light (...) transformation law, and follow with a discussion on why such an attempt must necessarily fail.

In The Agrarian Vision , Thompson argues that a better appreciation of agrarian ideals could lead to a more virtuous, more sustainable way of life. While I agree with Thompson in many respects, there are some aspects of the book that I question and others that I would like to hear Thompson explicate in greater detail. In this paper, I question Thompson’s claim that agrarian farmers and farming communities serve as ideal models of virtuous habits and good character. I challenge (...) Thompson’s use of virtue theory, particularly the notion that farming virtues can be acquired without participating in farming practices. In the end, I make the point that Thompson seems to vacillate between being realistic and being idealistic, which may seriously complicate our notions of responsibility and obligation in practice.

In lieu of an abstract, here is a brief excerpt of the content:The University and Democracy: A Response to “Dewey, Implementation, and Creating a Democratic Civic University”Lee A. McBride IIIira harkavy has given us much to consider. His paper, “Dewey, Implementation, and Creating a Democratic Civic University,” invites us to critically assess our democracy and the role of colleges and universities in the propagation of our democratic way of life. Harkavy suggests that universities are failing to fulfill their function, that (...) is, “to educate students to be ethical, empathetic, engaged, democratic citizens, and advance knowledge for the continuous betterment of the human condition” (50). He suggests that universities are central societal institutions in the world, and research universities are most central—“they develop new ideas and technologies, incubate businesses, serve as cultural and artistic centers, and are engines of local, national, and global economics” (50). Our universities produce our teachers and our teachers’ teachers; they shape the learning, values, and the aspirations of students (Harkavy 50). But, again, universities are not fulfilling their social function of “creating and sustaining an inclusive, just democratic society” (Harkavy 51). Harkavy boldly asserts that a revolutionary change is required in higher education if it is to fulfill its democratic function.Closed LoopI have a concern about the role of Research 1 (R1) universities in this picture. I am led to believe that R1 universities, like the University of Pennsylvania, exist in rarefied air. Penn, for example, has a ridiculous endowment—more than $20 billion. Penn apparently accepts only 9% of its applicants. The resources and demographics of R1 institutions are unlike those at state schools and small liberal arts colleges. The various canons, the faculty, and the student body at elite R1 universities have historically represented the thoughts, [End Page 76] experiences, and perplexities of well-heeled white heteronormative men. The vast majority of the faculty and students at R1 universities are predominantly of Anglo-European descent and a higher socioeconomic status. This gives me pause. If R1 universities are placed as the central engines of democratic fomenting, I worry that the faculty and students at R1 universities will direct research and social amelioration projects in particular directions and retain particular presuppositions that will buttress the continued flourishing of elite R1 universities. A closed loop. I worry that both the material and the social capital needed to (re)shape social conditions will arise only from and circulate only between those who attend elite R1 universities. I mean, Harkavy suggests that the departments, programs, and institutes at R1 universities create and sustain those knowledges and skills that produce the scholars and thoughtful people who will drive our K–12 education, who will fashion new cooperatives and entrepreneurial ventures, and who will become our community activists and political leaders. As such, the knowledge and skills to implement a more just and inclusive democracy will be disseminated from the R1 university. Harkavy also explains that it is necessary that universities strive to be democratic civic universities, sites where university folk work alongside members of the surrounding communities to address and ameliorate the problems on the ground. This “would involve significant and ongoing engagement of an institution’s comprehensive assets (academic, human, cultural, and economic) in partnership with community members to produce knowledge and educate ethical students with the ability to help create and maintain just, anti-racist, democratic societies” (Harkavy 53). The democratic civic university would then nurture a culture of democracy that exceeds mere voting practices— democracy as a way of life (Dewey 226). Prima facie, this seems like a noble goal. And yet, I still worry that those university folks who do this work will be a small representative group of people who bear particular life experiences and perhaps phenotypic markers.I would suggest that other sites outside of the R1 university (e.g., the trade union meeting, the settlement house, the church, the community garden, etc.) will need to be taken as legitimate sites of knowledge creation or legitimate sites of communication and joint activity (Collins 269). This would at least bring differing life experiences to the table; that is, it would bring differing life experiences to the fore and recognize alternative non-academic sources of insight and wisdom. These sites and alternative... (shrink)
