Current thinking and research on consciousness and the brain.

This essay asks why Aristotle, certainly no friend to unlimited democracy, seems so much more comfortable with unconstrained rhetoric in political deliberation than current defenders of deliberative democracy. It answers this question by reconstructing and defending a distinctly Aristotelian understanding of political deliberation, one that can be pieced together out of a series of separate arguments made in the Rhetoric, the Politics, and the Nicomachean Ethics.

"It seems that the human mind has first to construct forms independently before we can find them in things ... Knowledge cannot spring from experience alone, but only from a comparison of the inventions of the intellect with observed fact.".

absorbed state. (7.7) Empirically, a state like fantasy, selective attention, absent-minded day-dreaming and probably hypnosis, in which conscious experience is unusually resistant to distraction. Theoretically, a case in which access to the Global Workspace (GW) is controlled by a coherent context hierarchy , giving little opportunity for outside information to compete for conscious access (4.32).

I agree with Uzi Awret that Diego Velasquez's seminal painting, Las Meninas, is an expression of self-consciousness in many different ways. But my first response was to the feeling tone Velasquez evokes in his work, which felt dark and rather grim to me. I think this painting may be a meditation on the mortification of the flesh, a theme that was surely familiar to Velasquez. It is a contemplation of human vanity. Self-consciousness is not just a cognitive act. The so-called (...) 'self conscious emotions' include pride, vanity, shame and guilt; their cognitive components are self-aggrandizement, perfectionism, and self- criticism. The self-consciousness emotions are enormously powerful motivators in life. Pride and self-celebration can be seen in three-year olds. Starting in middle childhood, children can feel so intensely embarrassed at times that they want to sink into the ground. Mutual ridicule emerges in social play, a game of shaming others and avoiding self-shame. In adults, severe mental disorders like paranoia and depression are thought to be evoked by intense feelings of shame and constant self-criticism. Self-consciousness is a great force in human lives.

In the contemporary ethical discourse, we constantly take recourse to human rights and dignity, and frequently rights are said to be founded on dignity. However, when we examine this concept, we begin to doubt that this recourse is adequate, because dignity manifests two features that are difficult to reconcile with liberal values on which our societies are established. First, and the appearances notwithstanding, dignity is not a universalist concept; and second, it possesses a perfectionist side. A rapid historical survey will (...) help to understand the point, showing that the concept of dignity refers to a nature that is at the same time a task to perform. (shrink)

No understanding of morality has more zealous or influential defenders among academic philosophers than Kant’s. Yet as Michael Rosen demonstrates in The Shadow of God, there is a sense in which Kant’s critics take his conception of freedom more seriously nowadays than his defenders. As a result, contemporary versions of “Kantian ethics” often end up challenging what Rosen calls “the ethics of Kant,” not just the claims of rival moral theories. Rosen supports this surprising conclusion with some powerful arguments, showing (...) that we cannot make sense of Kantian moral philosophy or its extraordinary impact on modern philosophy while detaching it from Kant’s conception of transcendental freedom. But Rosen overstates the continuity between Kant and the Idealist philosophers that he inspired. Thinkers like Schiller, Schelling, and Hegel took Kant’s concept of transcendental freedom far more seriously than defenders of Kantian ethics do today. But precisely because they did so, they felt compelled to address a whole new set of problems, which could be solved only by radically transforming the conception of freedom that they received from Kant.

This work makes three valuable contributions to the study of human slips and errors.

This paper explores a remarkable convergence of ideas and evidence, previously presented in separate places by its authors. That convergence has now become so persuasive that we believe we are working within substantially the same broad framework. Taylor's mathematical papers on neuronal systems involved in consciousness dovetail well with work by Newman and Baars on the thalamocortical system, suggesting a brain mechanism much like the global workspace architecture developed by Baars (see references below). This architecture is relational, in the sense (...) that it continuously mediates the interaction of input with memory. While our approaches overlap in a number of ways, each of us tends to focus on different areas of detail. What is most striking, and we believe significant, is the extent of consensus, which we believe to be consistent with other contemporary approaches by Weiskrantz, Gray, Crick and Koch, Edelman, Gazzaniga, Newell and colleagues, Posner, Baddeley, and a number of others. We suggest that cognitive neuroscience is moving toward a shared understanding of consciousness in the brain. (shrink)

Anderson and Csima :245–264, 2014) defined a jump operator, the bounded jump, with respect to bounded Turing reducibility. They showed that the bounded jump is closely related to the Ershov hierarchy and that it satisfies an analogue of Shoenfield jump inversion. We show that there are high bounded low sets and low bounded high sets. Thus, the information coded in the bounded jump is quite different from that of the standard jump. We also consider whether the analogue of the Jump (...) Theorem holds for the bounded jump: do we have A≤bTB\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$A \le _{bT}B$$\end{document} if and only if Ab≤1Bb\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$A^b \le _1 B^b$$\end{document}?

After suggesting an operational definition for fringe experiences—as opposed to clearly conscious and clearly unconscious phenomena—we examine three empirical cases: The tip-of-the-tongue experience, the fringe experience of "wrongness," and the case of conscious focus on abstract, hard-to-image conscious contents. In each case, Mangan′s four major claims are explored in some detail. Most tasks seem to involve a combination of conscious experiences, complex unconscious representations, and multiple fringe experiences. The chief disagreement from this analysis involves vague experiences that are generally believed (...) to be focal: The case of currently topical abstract concepts, which are not reported as conscious images or percepts. In the interest of caution, it may be better to speak of "conscious access" to focal abstract concepts, rather than "conscious experience" of such concepts. There may be other vague but focally conscious phenomena, such as an intention to act, the signal for executing a prepared action, and so on. Mangan′s points are generally supported, with some qualifications. (shrink)

In addition to this much-needed clarification of the uses and abuses of the term "modernity," Yack here provides a fresh look at familiar modern ideas and practices such as nationalism, constitutionalism, and liberal democratic politics. Our world, the author suggests, offers us far stranger and more unexpected combinations that are dreamt of in modernist and postmodernist philosophies. His critique of the tendency to treat modernity as an integrated and coherent whole will expand the reader's vision to take in the broader (...) landscape of surprising and inconsistent features in the social and political world that surrounds us. The Fetishism of Modernities will be of interest to social, political and cultural theorists, intellectual historians and philosophers, as well as anyone with a stake in current debates about modernity and postmodernity.

Qu'est que la mathematique? Quel role y joue l'intuition? Sur quels principes repose-t-elle? Les Premiers ecrits de Bolzano proposent une reponse. Ils reunissent les oeuvres philosophiques, logiques et mathematiques les plus representatives de la periode de son activite publique, de 1804 a sa revocation de l'universite en 1819, et sont groupes autour de deux textes fondamentaux: les Contributions a un expose mieux fonde de la mathematique (1810) et la Demonstration purement analytique (1817), completee par des extraits de la Theorie des (...) fonctions. Les Contributions, bien que tributaires en partie de Kant, renouvellent l'heritage leibnizien en soulignant le caractere objectif de la science. Accueillies par Goethe - un petit ouvrage distingue par sa valeur et son esprit - et commentees par Husserl, elles constituent une premiere etude moderne des fondements de la mathematique, dont les notions de demonstration et d'organisation deductive du savoir sont les pivots. En annexe, Bolzano offre une critique penetrante de la philosophie de Kant. La Demonstration purement analytique, un petit classique d'histoire et de philosophie de la mathematique, inaugure avant Cauchy l'arithmetisation de l'analyse infinitesimale. Ces ecrits sont precedes d'une Introduction qui les etudie dans leurs contexte politique, culturel et scientifique. (shrink)

Ecrire en philosophie consiste à rechercher "le problème d'une oeuvre", affirme Deleuze après Bergson. En s'inspirant de cette recommandation, l'auteur cherche à construire le problème de l'oeuvre du "premier" Deleuze, d'Empirisme et subjectivité à Différence et répétition. Le problème central est celui de la définition de la pensée : que signifie penser et s'orienter dans la pensée? Comment commencer sans présupposés? Ce volume examine le point de départ de la pensée de Deleuze qui consiste dans la critique de l'image de (...) la pensée comme représentation. Il restitue fidèlement sa pensée sans simplification ni jargon. (shrink)
