    Dissipation and spontaneous symmetry breaking in brain dynamics

    Full text link
    We compare the predictions of the dissipative quantum model of brain with neurophysiological data collected from electroencephalograms resulting from high-density arrays fixed on the surfaces of primary sensory and limbic areas of trained rabbits and cats. Functional brain imaging in relation to behavior reveals the formation of coherent domains of synchronized neuronal oscillatory activity and phase transitions predicted by the dissipative model.Comment: Restyled, slight changes in title and abstract, updated bibliography, J.

    Beyond the American century: Walter Lippmann and American grand strategy, 1943-1950

    As the United States became a world Power, journalist and intellectual Walter Lippmann feared that it would become its own worst enemy. During and after the Second World War, he tried to steer the country towards coherent statecraft, to define the national interest and the limits of power, and give geopolitical expression to the role of the United States as the core of an Atlantic strategic system. But in response to world war, the Truman Doctrine, and the Korean War, he became pessimistic about the country's ability to conduct strategy effectively. In the prophetic tradition, he believed that a fatal symbiosis between America's growing strength and domestic politics led it towards crisis. Though at times ahistorical, Lippmann's concept of strategy deserves attention for its dialogue between power and identity, for its questioning of “ends” as well as means, and for its focus on the danger of self-defeating behaviour

    From Knowledge, Knowability and the Search for Objective Randomness to a New Vision of Complexity

    Full text link
    Herein we consider various concepts of entropy as measures of the complexity of phenomena and in so doing encounter a fundamental problem in physics that affects how we understand the nature of reality. In essence the difficulty has to do with our understanding of randomness, irreversibility and unpredictability using physical theory, and these in turn undermine our certainty regarding what we can and what we cannot know about complex phenomena in general. The sources of complexity examined herein appear to be channels for the amplification of naturally occurring randomness in the physical world. Our analysis suggests that when the conditions for the renormalization group apply, this spontaneous randomness, which is not a reflection of our limited knowledge, but a genuine property of nature, does not realize the conventional thermodynamic state, and a new condition, intermediate between the dynamic and the thermodynamic state, emerges. We argue that with this vision of complexity, life, which with ordinary statistical mechanics seems to be foreign to physics, becomes a natural consequence of dynamical processes.Comment: Phylosophica

    The philosophy of European Law with "chaos out of order" set-up and functioning

    Get PDF
    In reconsideration of the composition and operation of European law, it is the description of its underlying mentality that may cast best light on the query whether European law is the extension of domestic laws or a sui generis product. As to its action, European law is destructive upon the survival of traditions of legal positivism, for it recalls post modern clichés rather. Like a solar system with planets, it is two-centred from the beginning, commissioning both implementation and judicial check to member states. As part of global post modernism, a) European law stems from artificial reality construction freed from particular historical experience and, indeed, anything given hic et nunc. By its operation, b) it dynamises large structures and sets in motion that what is chaos itself. It is owing to reconstructive human intent solely that any outcome can at all be seen as fitting to some ideal of order, albeit neither operation nor daily management strives for implementing any systemicity. This is the way in which the European law becomes adequate reflection of the underlying (macro) economic basis, which it is to serve as superstructure. Accordingly, c) the entire construct is operated (as integrated into one well-working unit) within the framework of an artificially animated dynamism. With its “order out of chaos” philosophy it assures member states’ standing involvement and competition, achieving a flexibly self-adapting (and unprecedentedly high degree of) conformity
