In 1933 Godel introduced a calculus of provability (also known as modal logic S4) and left open the question of its exact intended semantics. In this paper we give a solution to this problem. We find the logic LP of propositions and proofs and show that Godel's provability calculus is nothing but the forgetful projection of LP. This also achieves Godel's objective of defining intuitionistic propositional logic Int via classical proofs and provides a Brouwer-Heyting-Kolmogorov style provability semantics for Int which (...) resisted formalization since the early 1930s. LP may be regarded as a unified underlying structure for intuitionistic, modal logics, typed combinatory logic and λ-calculus. (shrink)

Individual semiotic systems interpreting their environment are not well understood from the externalist approach typical of the scientific method. Science constructs probabilities describing large populations of systems, not individuals. The Umwelt, as the individually experienced/created aspects of the habitat aspect of its population’s ecological niche, is given an internalist understanding within the framework of the compositional hierarchy. Vagueness is an important aspect of the internalist condition. It is selectively reduced momentarily by creative choices that can have a Peircean semiotic formulation, (...) and which are often unpredictable externally, thereby appearing to be chance events.

The civilizational turn in sociological theory is best understood as an attempt to do full justice to the autonomy of culture (against all versions of structural-functional theory) without conceding the issue to cultural determinism. Civilizational formations are based on combinations of cultural visions of the world with regulative frameworks of social life, but the relationship between the two levels is open to conflicting interpretations and strategic uses of them. Axial age civilizations open up new structural and historical dimensions of interaction (...) between cultural and social patterns, and are therefore central to the agenda of civilizational analysis. Among the later breakthroughs which draw on Axial sources, the emergence of modernity stands out as particularly important; the cultural and political program of modernity may be seen as a new and distinctive civilization, but it remains open to more or less formative influences from older civilizational legacies.

Research suggests political identity has strong influence over individuals’ attitudes and beliefs, which in turn can affect their behavior. Likewise, firsthand experience with an issue can also affect attitudes and beliefs. A large survey of Americans was analyzed to investigate the effects of both political identity and personal impact on individuals’ reactions to the COVID-19 pandemic. Results show that political identity and personal impact influenced the American public’s attitudes about and response to COVID-19. Consistent with prior research, political identity exerted (...) a strong influence on self-reports of emotional distress, threat perception, discomfort with exposure, support for restrictions, and perception of under/overreaction by individuals and institutions. The difference between Democrats and Republican responses were consistent with their normative value differences and with the contemporary partisan messaging. Personal impact exerted a comparatively weaker influence on reported emotional distress and threat perception. Both factors had a weak influence on appraisal of individual and government responses. The dominating influence of political identity carried over into the bivariate relations among these self-reported attitudes and responses. In particular, the appraisal of government response divided along party lines, tied to opposing views of whether there has been over- or under-reaction to the pandemic. The dominance of political identity has important implications for crisis management and reflects the influence of normative value differences between the parties, partisan messaging on the pandemic, and polarization in American politics.

Many psychological studies of categorization and reasoning use undergraduates to make claims about human conceptualization. Generalizability of findings to other populations is often assumed but rarely tested. Even when comparative studies are conducted, it may be challenging to interpret differences. As a partial remedy, in the present studies we adopt a 'triangulation strategy' to evaluate the ways expertise and culturally different belief systems can lead to different ways of conceptualizing the biological world. We use three groups (US bird experts, US (...) undergraduates, and ordinary Itza' Maya) and two sets of birds (North American and Central American). Categorization tasks show considerable similarity among the three groups' taxonomic sorts, but also systematic differences. Notably, US expert categorization is more similar to Itza' than to US novice categorization. The differences are magnified on inductive reasoning tasks where only undergraduates show patterns of judgment that are largely consistent with current models of category-based taxonomic inference. The Maya commonly employ causal and ecological reasoning rather than taxonomic reasoning. Experts use a mixture of strategies (including causal and ecological reasoning), only some of which current models explain. US and Itza' informants differed markedly when reasoning about passerines (songbirds), reflecting the somewhat different role that songbirds play in the two cultures. The results call into question the importance of similarity-based notions of typicality and central tendency in natural categorization and reasoning. These findings also show that relative expertise leads to a convergence of thought that transcends cultural boundaries and shared experiences. (shrink)

In this paper, I explore the links between liberal political theory and the evaluative nature of medical classification, arguing for stronger recognition of those links in a liberal model of medical practice. All judgments of medical or psychiatric "dysfunction," I argue, are fundamentally evaluative, reflecting our collective willingness or reluctance to tolerate and/or accommodate the conditions in question. Illness, then, is "socially constructed." But the relativist worries that this loaded phrase evokes are unfounded; patients, doctors, and communities will agree in (...) the vast majority of cases about what counts as illness. Where they cannot come to agreement, however, we are faced with precisely the sort of dispute about values and ways of life that the institutions of the liberal state are designed to accommodate. I accordingly sketch a model of medical practice, based loosely on Jürgen Habermas's political theories, designed to maximize both our awareness and our understanding of these disputes. (shrink)

Stuart, SN An extraordinary concentration of intellectual effort in Vienna during 1924 to 1936 produced a new standard of philosophy which remains an important touchstone today, despite some shortcomings which have become apparent. The contributors were animated to regain clarity of collective thought, felt to be lost in the convulsion of the Great War. As its topics were quickly taken up in Prague and Berlin, Cambridge and Harvard, the Vienna Circle came to exert an important, international influence on the intellectual (...) and scientific history of the twentieth century. In particular, its program for separating knowledge from nonsense informed the emerging international Humanist movement. (shrink)

This article addresses the ways in which art and philosophy have been discursively used to conceptualize critical political changes and frame narratives of liberation by including and excluding primitive consciousness simultaneously. More concretely, it analyzes the contribution of art and philosophy to the understanding of history and post-history through different representations of black bodies, black desires, and black agencies in the novels She (1886) by Rider Haggard and The Quest of the Silver Fleece (1911) by W. E. B. Du Bois. (...) At stake is the question of the archeology of the past as a living memory in the post-historical time. This past is politically relevant especially if its cognitive fossils negate the idea of exhausted primitive consciousness in the modern world and give meanings to incongruous bedfellows such as civilization and slavery, neoliberalism and poverty, democracy and Nazism, globalization, terrorism and racism, liberalism and homophobia. Arguably, the triumph of scientific ideas has left us with a perpetual quest for liberation rather than the actualization of liberation as a world phenomenon. I hypothesize the relation between exhaustible elements of technical consciousness simulating progress and their inexhaustible materiality at critical historical junctures as a struggle for taste and self-determination. Critical in this relation is the sense that not only primitive stages of consciousness are never fully exhausted at historical junctures, but that one never comes close to thinking about genuine liberation without engaging with real world matters both domestic/intimate and foreign.

This paper is based on four assumptions concerning the analysis of the construction of collective identities. First, such construction, like power and economic relations, is an analytically autonomous basic component of the construction of social life. Second, such constructions have been going on in all human societies throughout history. Third, all such patterns of collective identity have been continually constructed from some basic yet continually changing building blocks, codes or themes - especially those of primordiality, civility and `sacredness'. The paper (...) focuses on the different patterns of modern nation states in the framework of the more general approach to the construction of collective identities. This analysis of different modern nation states indicates that despite common characteristics, there developed great differences in their construction; in the analysis of such differences it is very important to take into account the historical and civilizational backgrounds of the respective societies.
