In one of his last writings, Life: Experience and Science, Michel Foucault argued that twentieth-century French philosophy could be read as dividing itself into two divergent lines: on the one hand, we have a philosophical stream which takes individual experience as its point of departure, conceiving it as irreducible to science. On the other hand, we have an analysis of knowledge which takes into account the concrete productions of the mind, as are found in science and human practices. In order (...) to account for this division, Foucault opposed epistemologists such as Cavaillès and Canguilhem to phenomenologists such as Merleau-Ponty and Sartre but, also, and more particularly, he opposed Poincaré to Bergson. The latter was presented by Foucault as being the key-figure of the ?philosophy of experience? at the beginning of the twentieth century. Fifteen years later, in his Deleuze and in the Logics of Worlds, Alain Badiou again uses this dual structure in his interpretation of the past hundred years of French thought. He employs a series of oppositional couples: himself and Deleuze, Lautmann and Sartre, and, finally, Brunschvicg and Bergson. On the one hand a ?mathematical Platonism? and on the other a ?philosophy of vital interiority.? This Manichean reading of philosophy, and the strategic use of the figure of Bergson has, itself, a long tradition. It was also proposed by Althusser who, following Bachelard, opposed his standpoint to any form of ?empiricism.? Althusser developed his thought from a tradition of Marxist thinkers and ideologists, which included Politzer's and Nizan's critique of bourgeois philosophy and, even before that, neo-Kantians such as the philosophers of the Revue de métaphysique et de morale. The aim of this essay is to deconstruct and to put into its precise context of production this series of genealogies which entails the mobilization of Bergsonism and of the name ?Bergson.? By doing so, I hope to weight the importance of Bergsonism in twentieth-century French philosophy, in both its ?positive? and its ?negative? aspect. The essay will proceed regressively, taking into account figures such as Althusser, Badiou, Deleuze, Foucault, Canguilhem, Cavaillès, Sartre, Merleau-Ponty, but also Polizer, Brunschvicg and Alain. The conclusion of the essay is an attempt at reading the ?Bergson renaissance? in the light of new discoveries in genetics and the cognitive sciences and to tie it to the renewal of studies in the history of French philosophy.

A novel and versatile polarization-entanglement scheme is adopted to investigate the violation of the EPR local realism for a non-maximally entangled two-photon system according to the recent nonlocality proof by Lucien Hardy. In this context the adoption of a sophisticated detection method allows direct determination of any element of physical reality (viz., determined with probability equal to unity in the words of Einstein, Podolsky and Rosen) for the pair system within complete measurements that are largely insensitive to the detector quantum-efficiencies (...) and noise.

Recently the complexity of discursive practices has been widely acknowledged by the humanities and social sciences. In fact, to know anything is to know in terms of one or more discourse. The "discursive turn" in psychology may be considered as a new paradigm oriented to a correct study of (wo)man only if it is able to grasp the semiotical ground of psychic experience both as an "effort after meaning" and as a "struggle over meaning." In this sense the notion of (...) "diatext" has been proposed as a contribution in working out a psychosemiotical approach to understand how the discursive practices assign subject-positions to the agents of each interlocution scenario.

Because Bertrand Russell adopted much of the logical symbolism of Peano, because Russell always had a high regard for the great Italian mathematician, and because Russell held the logicist thesis so strongly, many English-speaking mathematicians have been led to classify Peano as a logicist, or at least as a forerunner of the logicist school. An attempt is made here to deny this by showing that Peano's primary interest was in axiomatics, that he never used the mathematical logic developed by him (...) for the reduction of mathematical concepts to logical concepts, and that, instead, he denied the validity of such a reduction.

The foundation of Mathematics is both a logico-formal issue and an epistemological one. By the first, we mean the explicitation and analysis of formal proof principles, which, largely a posteriori, ground proof on general deduction rules and schemata. By the second, we mean the investigation of the constitutive genesis of concepts and structures, the aim of this paper. This “genealogy of concepts”, so dear to Riemann, Poincaré and Enriques among others, is necessary both in order to enrich the foundational analysis (...) with an often disregarded aspect (the cognitive and historical constitution of mathematical structures) and because of the provable incompleteness of proof principles also in the analysis of deduction. For the purposes of our investigation, we will hint here to a philosophical frame as well as to some recent experimental studies on numerical cognition that support our claim on the cognitive origin and the constitutive role of mathematical intuition.

We propose a new interpretation of objective deterministic chances in statistical physics based on physical computational complexity. This notion applies to a single physical system (be it an experimental set--up in the lab, or a subsystem of the universe), and quantifies (1) the difficulty to realize a physical state given another, (2) the 'distance' (in terms of physical resources) from a physical state to another, and (3) the size of the set of time--complexity functions that are compatible with the physical (...) resources required to reach a physical state from another.

We review the dissipative quantum model of the brain and present recent developments related to the role of entanglement, quantum noise and chaos in the model.
Of course there is a long history of such sayings in all the world’s main spiritual traditions. Socrates’ remark reminds us at once of Solon’s doleful doctrine that we should call no man happy until he is dead (Herodotus Histories Book 1; Aristotle Nicomachean Ethics 1100a11). And Bonhoeffer’s famous saying, while it echoes the typical teaching of many Christian spiritual masters, for instance St Thomas à Kempis and Bianco da Siena (the author of that beautiful hymn “Come down O (...) Love Divine”), is ultimately just a paraphrase of Jesus’ even more famous saying that anyone who wants to follow him must “deny himself, and take up his cross, and follow me” (Matthew 16.24).

Is any unified theory of brain function possible? Following a line of thought dating back to the early cybernetics (see, e.g., Cordeschi, 2002), Clark (in press) has proposed the action-oriented Hierarchical Predictive Coding (HPC) as the account to be pursued in the effort of gaining the “Grand Unified Theory of the Mind”—or “painting the big picture,” as (Edelman 2012) put it. Such line of thought is indeed appealing, but to be effectively pursued it should be confronted with experimental findings and (...) explanatory capabilities (Edelman, 2012). -/- The point we are making in this note is that a brain with predictive capabilities is certainly necessary to endow the agent situated in the environment with forethought or foresight, a crucial issue to outline the unified account advocated by Clark. But the capacity for forethought is deeply entangled with the capacity for emotions and when emotions are brought into the game, cognitive functions become part of a large-scale functional brain network. However, for such complex networks a consistent view of hierarchical organization in large-scale functional networks has yet to emerge (Bressler and Menon, 2010), whilst heterarchical organization is likely to play a strategic role (Berntson et al., 2012). This raises the necessity of a multilevel approach that embraces causal relations across levels of explanation in either direction (bottom–up or top–down), endorsing mutual calibration of constructs across levels (Berntson et al., 2012). Which, in turn, calls for a revised perspective on Marr's levels of analysis framework (Marr, 1982). In the following we highlight some drawbacks of Clark's proposal in addressing the above issues.

Various conceptual approaches to the notion of information can currently be traced in the literature in logic and formal epistemology. A main issue of disagreement is the attribution of truthfulness to informational data, the so called Veridicality Thesis (Floridi 2005). The notion of Epistemic Constructive Information (Primiero 2007) is one of those rejecting VT. The present paper develops a formal framework for ECI. It extends on the basic approach of Artemov’s logic of proofs (Artemov 1994), representing an epistemic logic based (...) on dependent justifications, where the definition of information relies on a strict distinction from factual truth. The definition obtained by comparison with a Normal Modal Logic translates a constructive logic for “becoming informed”: its distinction from the logic of “being informed”—which internalizes truthfulness—is essential to a general evaluation of information with respect to truth. The formal disentanglement of these two logics, and the description of the modal version of the former as a weaker embedding into the latter, allows for a proper understanding of the Veridicality Thesis with respect to epistemic states defined in terms of information.

Our visual experience seems to suggest that no continuous curve can cover every point of the unit square, yet in the late nineteenth century Giuseppe Peano proved that such a curve exists. Examples like this, particularly in analysis (in the sense of the infinitesimal calculus) received much attention in the nineteenth century. They helped instigate what Hans Hahn called a “crisis of intuition”, wherein visual reasoning in mathematics came to be thought to be epistemically problematic. Hahn described this “crisis” (...) as follows: Mathematicians had for a long time made use of supposedly geometric evidence as a means of proof in much too naive and much too uncritical a way, till the unclarities and mistakes that arose as a result forced a turnabout. Geometrical intuition was now declared to be inadmissible as a means of proof... (p. 67) Avoiding geometrical evidence, Hahn continued, mathematicians aware of this crisis pursued what he called “logicization”, “when the discipline requires nothing but purely logical fundamental concepts and propositions for its development.” On this view, an epistemically ideal mathematics would minimize, or avoid altogether, appeals to visual representations. This would be a radical reformation of past practice, necessary, according to its advocates, for avoiding “unclarities and mistakes” like the one exposed by Peano. (shrink)
In his classic introduction to the subject, Cognitive Therapy and the Emotional Disorders, Aaron Beck observes that “the philosophical underpinnings” of cognitive therapy’s (CT) approach to the emotional disorders “go back thousands of years, certainly to the time of the Stoics, who considered man’s conceptions (or misconceptions) of events rather than the events themselves as the key to his emotional upsets” (Beck 1976, 3). But beyond acknowledging that the stoics anticipated the central insight of CT, Beck has very little to (...) say about the philosophical underpinnings of CT, content it would seem for it to be an empirically grounded system of psychological principles and therapeutic methods. Yet even this little .. (shrink)
Starting from a recent paper by S. Kaufmann, we introduce a notion of conjunction of two conditional events and then we analyze it in the setting of coherence. We give a representation of the conjoined conditional and we show that this new object is a conditional random quantity, whose set of possible values normally contains the probabilities assessed for the two conditional events. We examine some cases of logical dependencies, where the conjunction is a conditional event; moreover, we give the (...) lower and upper bounds on the conjunction. We also examine an apparent paradox concerning stochastic independence which can actually be explained in terms of uncorrelation. We briefly introduce the notions of disjunction and iterated conditioning and we show that the usual probabilistic properties still hold. (shrink)
Two problems related to the biological identity of living beings are faced: the who-problem (which are the biological properties making that living being unique and different from the others?); the persistence-problem (what does it take for a living being to persist from a time to another?). They are discussed inside a molecular biology framework, which shows how epigenetics can be a good ground to provide plausible answers. That is, we propose an empirical solution to the who-problem and to the persistence-problem (...) on the basis of the new perspectives opened by a molecular understanding of epigenetic processes. In particular, concerning the former, we argue that any living being is the result of the epigenetic processes that have regulated the expression of its genome; concerning the latter, we defend the idea that the criterion for the persistence of its identity is to be indicated in the continuity of those epigenetic processes. We also counteract possible objections, in particular (1) whether our approach has something to say at a metaphysical level; (2) how it could account for the passage from the two phenotypes of the parental gametes to the single phenotype of the zygote; (3) how it could account for the identity of derivatives of one living being that continue to live disjoined from that original living being; (4) how it could account for higher mental functions.

The value of resting electroencephalogram (EEG) in revealing neural constitutes of consciousness (NCC) was examined. We quantified the dynamic repertoire, duration and oscillatory type of EEG microstates in eyes-closed rest in relation to the degree of expression of clinical self-consciousness. For NCC a model was suggested that contrasted normal, severely disturbed state of consciousness and state without consciousness. Patients with disorders of consciousness were used. Results suggested that the repertoire, duration and oscillatory type of EEG microstates in resting condition quantitatively (...) related to the level of consciousness expression in brain-damaged patients and healthy-conscious subjects. Specifically, results demonstrated that (a) decreased number of EEG microstate types was associated with altered states of consciousness, (b) unawareness was associated with the lack of diversity in EEG alpha-rhythmic microstates, and (c) the probability for the occurrence and duration of delta-, theta- and slow-alpha-rhythmic microstates were associated with unawareness, whereas the probability for the occurrence and duration of fast-alpha-rhythmic microstates were associated with consciousness. In conclusion, resting EEG has a potential value in revealing NCC. This work may have implications for clinical care and medical–legal decisions in patients with disorders of consciousness. (shrink)
