In this paper, we consider three different search strategies for a cut-free sequent system formalizing orthologic, and estimate the respective search spaces. Applying backward search, there are classes of formulae for which both the minimal proof length and the search space are exponential. In a combined forward and backward approach, all proofs are polynomial, but the potential search space remains exponential. Using a forward strategy, the potential search space becomes polynomial yielding a polynomial decision procedure for orthologic and the word problem for free ortholattices. 相似文献

A form of logic called relational and contextual reasoning is put forward as an improvement over other, more familiar types of logic. Developmental ideas are used to show how maturity ordinarily leads people away from binary (true/false) logic to systems of reasoning that are more subtle and better suited to making decisions in the face of ambiguity. 相似文献

There is a growing understanding that addressing the global crisis facing humanity will require new methods for knowing, understanding, and valuing the world. Narrow, disciplinary, and reductionist perceptions of reality are proving inadequate for addressing the complex, interconnected problems of the current age. The pervasive Cartesian worldview, which is based on the metaphor of the universe as a machine, promotes fragmentation in our thinking and our perception of the cosmos. This divisive, compartmentalized thinking fosters alienation and self‐focused behavior. I aim to show in this essay that healing the fragmentation that is at the root of the current world crises requires an integrated epistemology that embraces both the rational knowledge of scientific empiricism and the inner knowledge of spiritual experience. This “deep science” transcends the illusion of separateness to discern the unity, the unbroken wholeness, that underlies the diverse forms of the universe. Our perception of connectedness, of our integral place in the web of life, emerges as an attribute of our connection with the eternal, beatific source of all existence. This awakened spiritual vision “widens our circle of understanding and compassion, to embrace all living creatures in the whole of nature” (Einstein, quoted in Goldstein [1976] 1987). Our behavior, as it emerges naturally out of our perception of the sacredness of the natural world, will naturally embody love and respect for all life forms. This vision promotes the healing of our long‐standing alienation from the natural world and offers hope for renewal in the midst of widespread cultural deterioration and environmental destruction. 相似文献

Near-death life reviews pose a challenge to current memory research in terms of the sheer amount of instantaneous and empathetic information recall. Advances in quantum physics, biomechanics, holographic information theory, and consciousness studies support for the first time a fully realizable quantum biomechanical basis for near-death life reviews. We introduce the unifying paradigm of the quantum hologram as a non-local carrier of information. We further investigate the interrelated phenomena of non-local communications, and the electromagnetic zero-point field. Recent confirmation of the zero-point field lends credibility to vast memory storage capabilities outside the physical body. Microtubules are considered to be key components in non-local, quantum processes critical to human consciousness. Discovery of the liquid crystalline nature of the human body provides further support for our model. Microtubules, deoxyribonucleic acid (DNA), and the entire brain are described as communicating non-locally with virtually unlimited memory storage capacity. 相似文献

Summary Well known quantum and time paradoxes, and the difficulty to derive the second law of thermodynamics, are proposed to be the
result of our historically grown paradigm for energy: it is just there, the capacity to do work, not directly related to change.
When the asymmetric nature of energy is considered, as well as the involvement of energy turnover in any change, so that energy
can be understood as fundamentally “dynamic”, and time-oriented (new paradigm), these paradoxes and problems dissolve. The
most basic consequence concerns the particle-wave dualism. For a reversible inter-conversion of a particle into a wave, subject
to a dynamic energy, a self-image of information has to be generated: quantum theory has to be complemented by a theory of
information. Then, quantum processes can be derived from classical ones and the second law of thermodynamics with the tendency
of increasing entropy follows in a straightforward way. 相似文献

Designed as an introductory lecture for the conference “Einstein, God and Time,” this essay provides a brief survey of three sets of relations—between Einstein and time, God and time, and Einstein and God. The question is raised whether Einstein's rejection of absolute time held any implications for theology. It is argued that, despite Einstein's denial and his exemplary caution, the fact that Isaac Newton had associated absolute space and absolute time with a deity who constituted them meant that a revisitation of theological questions was inevitable. Consideration is then given to the time‐lessness and changelessness of God, with a brief reference to eschatological issues. The question whether there might be parallels between the renunciation of Newtonian time by physicists and by Christian theologians is discussed with reference to recent commentary on the eschatological thinking of Jürgen Moltmann. Whether Einstein himself would have sympathized with these theologies is to be doubted, given his antipathy to anthropomorphic and anthropopathic concepts of deity. Finally, in exploring Einstein's sometimes whimsical use of theological language, it becomes necessary to acknowledge that his well‐known affirmation of the complementarity of science and religion rested on a distinctive construction of religion that allowed him to say he was a “deeply religious unbeliever.” Attempts to categorize his convictions, or to appropriate them for conventional theistic purposes, miss their subtlety and their apophatic resonances. 相似文献

Abstract. I review some characteristic aspects of quantum reality and make the connection to Pierre Teilhard de Chardin's vision and a generally new quantum perspective of biological evolution. The quantum phenomena make it possible to conclude that the basis of the material world is nonmaterial; that the nature of reality is that of an indivisible wholeness; and that elementary particles possess aspects of consciousness in a rudimentary way. The quantum perspective of evolution makes it possible to conclude that the emergence of complex order in the biosphere is not from nothing (ex nihilo) but by the actualization of virtual quantum states—that is, by actualizing empty states which are part of the mathematical structure of material systems, representing a logical order that is not real in a material sense but, predetermined by system conditions, has the potential to become real in quantum jumps. I show how the existence of virtual states makes it possible to suggest that a transcendent reality underlies the visible order of the world and is immanent to it; and constantly new forms evolve from it. 相似文献

Abstract. I respond to Carl Helrich's criticism of my proposition that the emergence of complex order in the universe is from Virtual State Actualization (VSA). The question is discussed as to whether quantum theory is able to afford any kind of quantum ontology or whether it merely allows an epistemological view. I point out that, even though many contradictory interpretations of quantum theory are currently possible, the concept of VSA is based on molecular properties that are so simple and factual that they are beyond interpretation. Helrich's appeal for caution in proceeding from physical reality to Divine Reality is wholeheartedly supported and a detailed discussion is given. 相似文献

Abstract. I respond to Stanley Klein's critique of my essay “Quantum Reality, the Emergence of Complex Order from Virtual States, and the Importance of Consciousness in the Universe,” arguing in support of the necessity to derive a quantum perspective of evolution rather than adhering to an essentially classical view. In response to Klein's criticism of my concept of a cosmic morality, the origins of that concept are traced back to Zeno of Citium. I wholeheartedly embrace Klein's suggestion that the new science inspires views of the human condition that can help us make the world a better place. 相似文献
