It works perfectly well but nobody seems to know why. It has been argued that the difficulty in understanding quantum theory is our failed attempt to force onto it a wrong conceptual scheme, wanting at all costs to think about the “objects” of the theory as, precisely, objects, i.e., entities having continuously actual spatiotemporal properties. This too restrictive spatiotemporal scheme is obviously incorrect, as also underlined by the Einsteinian revolution, but then what would be the correct one? Many thinkers have suggested that we must simply surrender to the fact that our physical world is one of immanent powers and potencies. Aristotle did so ante (quantum) litteram, followed by scholars like Heisenberg, Primas, Shimony, Piron, Kastner, Kauffman, de Ronde, just to name a few, including the authors who were both students of Piron in Geneva. However, if on the one hand a potentiality ontology puts the accent on the processes of change, responsible for the incessant shifts between actual and potential properties, on the other hand it does not tell what these changes are all about. In other words, the (metaphysical) question remains of identifying the nature of the bearer of these potencies, or potentialities, and of the entities that are capable of actualizing them. It is the purpose of the present article to emphasize that the above question has found a comprehensive answer in the recent Conceptuality Interpretation of Quantum Mechanics, which we believe offers the missing ontology to make the theory fully intelligible, and even intuitive. In doing this, we will also emphasize the importance of carefully distinguishing the different conceptual layers that are contained in its explanatory edifice, as only in this way one can properly understand and fully appreciate the explanatory power it offers, without promoting undue reductionisms and/or anthropomorphizations. Whence deep realism for Everettian quantum mechanics? Jonas R. Becker Arenhart Raoni Wohnrath Arroyo It has been advanced that one cannot legitimately be a scientific re- alist about X without delving into deep metaphysical questions about X: this is ‘deep’ realism (as opposed to the ‘shallow’ or ersatz realism).

  • The Panpsychist Worldview
    THE PANPSYCHIST WORLDVIEW CHALLENGING THE NATURALISM-THEISM DICHOTOMY Written by Edwin Oldfield Master’s thesis (E-level essay) 15 HP, Spring 2019. Studies in faith and worldviews Supervisor: Mikael Stenmark, prof. Philosophy of religion Department of Theology Uppsala University 2019-06-03 Abstract The discussion of worldviews is today dominated by two worldviews, Theism and Naturalism, each with its own advantages and problems. Theism has the advantage of accommodating the individual with existential answers whilst having problems with integrating more recent scientific understandings of the universe. Naturalism on the other hand does well by our developments of science, the problem being instead that this understanding meets difficulty in answering some of the essentials of our existence: questions of mentality and morality. These two views differ fundamentally in stances of ontology and epistemology, and seem not in any foreseeable future to be reconcilable. To deal with this issue, Panpsychism is presented here as the worldview that can accommodate for both existential issues and scientific understanding. 1 Table of contents 1.0 Introduction ................................................................................................................. 3 1.1 Purpose and Questions ............................................................................................. 3 1.2 Limitations ............................................................................................................... 5 1.3 Methodology ...........................................................................................................

The event gathered more than 50 scholars from diferent disciplines, ranging from pure mathematics to visual arts, and from multiple regions of the world, including Argentina, Austria, Canada, Chile, France, Germany, Italy, Japan, Poland and the United States, to animate an interdisciplinary dialogue about funda- mental issues of science and society. ‘Entanglement’ is a genuine quantum phenomenon, in the sense that it has no counter- part in classical physics. It was originally identifed in quantum physics experiments by considering composite entities made up of two (or more) sub-entities which have interacted in the past but are now sufciently distant from each other. If joint measurements are per- formed on the sub-entities when the composite entity is in an ‘entangled state’, then the sub-entities exhibit, despite their spatial separation, statistical correlations (expressed by the violation of ‘Bell inequalities’) which cannot be represented in the formalism of classi- cal physics.

  • Superstition in the Machine
    Superstition in the Machine Alexander Riegler Center Leo Apostel, Vrije Universiteit Brussel Krijgskundestr. 33, B-1160 Brussels, Belgium [email protected] Abstract. It seems characteristic for humans to detect structural patterns in the world to anticipate future states. Therefore, scientific and common sense cogni- tion could be described as information processing which infers rule-like laws from patterns in data-sets. Since information processing is the domain of com- puters, artificial cognitive systems are generally designed as pattern discoverers. This paper questions the validity of the information processing paradigm as an explanation for human cognition and a design principle for artificial cogni- tive systems. Firstly, it is known from the literature that people suffer from conditions such as information overload, superstition, and mental disorders. Secondly, cognitive limitations such as a small short-term memory, the set- effect, the illusion of explanatory depth, etc. raise doubts as to whether human information processing is able to cope with the enormous complexity of an infi- nitely rich (amorphous) world. It is suggested that, under normal conditions, humans construct information rather than process it. The constructed information contains anticipations which need to be met. This can be hardly called information processing, since patterns from the “outside” are not used to produce action but rather to either justify an- ticipations or restructure the cognitive apparatus. When it fails, cognition switches to pattern processing, which, given the amorphous nature of the experiential world, is a lost cause if these patterns and inferred rules do not lead to a (partial) reorganisation of internal structures such that constructed anticipations can be met again.

  • Some Remarks on the Metaphysics and Epistemology of the Creation–Discovery View
    Some Remarks on the Metaphysics and Epistemology of the Creation–Discovery View Christian de Ronde∗ Federico Holik† Wim Christiaens‡ In this article we want to discuss the meaning of the violation of Bell inequalities by macroscopical systems as proposed by Diederik Aerts in several examples [1, 2, 3]. We will draw on recent research that has focused on Aerts’ contributions to the debate concerning the interpretation of the EPR-paradox and the violation of Bell inequalities by quantum entities [4]. This also requires a discussion of the so-called creation-discovery view (CD). CD makes explicit the metaphysical and epistemological principles according to which Aerts develops his analyses of the Bell inequalities. A discussion of a number of these principles will be the main goal of this presentation. We will discuss a central epistemological thesis and a central metaphysical thesis. 1. CD-epistemology. CD is a “double helix” of realism and idealism: on the one hand it adopts a strong realist stance by stating that a physical entitiy is something that exists in itself and independent of man; on the other hand it considers a real entity to be a construction that has to be understood in terms of real and possible creation-discoveries. It would appear that according to CD reality is both mind-independent and a human construction. 2. CD-metaphysics. Aerts has coined the term “biomousa” to designate the central process at work in physical reality [5]. The biomousa is not just the structure of change, it is the structure of creativity. Aerts solves the problem of CD-epistemology by making the biomousa (reality) itself a construction process, i.e., a process of creation–discovery.

  • An Enduring Philosophical Agenda. Worldview Construction As a Philosophical Method
    An Enduring Philosophical Agenda. Worldview Construction as a Philosophical Method. Clément Vidal ([email protected]) Vrije Universiteit Brussel Abstract: Is there such a thing as a philosophical method? It seems that there are as many philosophical methods as there are philosophies. A method is any procedure employed to achieve a certain aim. So, before proposing a method, we have to tackle the delicate question: “what is the aim of philosophy?”. At the origin of philosophy, there is a questioning about the world. The worldview approach developed by Leo Apostel (Apostel, Van der Veken 1991) elegantly explicit those fundamental questions. As we answer them, we come up with a worldview. Using this framework, this paper consider answering this enduring philosophical agenda as the primary aim of philosophy. However, we argue that philosophical worldviews constitute a particular class of possible worldviews. With the help of three analogies, we give guidelines to construct such worldviews. The next step is to compare the relative strength of philosophical worldviews. Precise evaluation standards to compare and confront worldviews are proposed. Some problems for worldview diffusion are then expounded. We close with basic hypotheses to build an integrative philosophical worldview. Keywords: metaphilosophy, worldview, weltanschauung, philosophical method, philosophical agenda, task of philosophy, systematic philosophy, speculative philosophy. Comments are welcome! 10/05/2007 1 Contents. 1 Introduction .....................................................................................................................................

  • The Dilemma of Quantum Individuality Beyond Particle Metaphysics
    The Dilemma of Quantum Individuality Beyond Particle Metaphysics Christian de Ronde1;2;3;4;5 and Raimundo Fernández-Mouján1;5 1. University of Buenos Aires 2. Philosophy Institute Dr. A. Korn, UBA-CONICET 3. National University Arturo Jauretche, Argentina. 4. Federal University of Santa Catarina, Brasil. 5. Center Leo Apostel for Interdisciplinary Studies, Vrije Universiteit Brussel, Belgium. Abstract It is commonly claimed that quantum mechanics makes reference to a microscopic realm constituted by elementary particles. However, as first famously noticed by Erwin Schrödinger, it is not at all clear what these quantum particles really are. According to the specialized literature, it is not even clear if each of these microscopic entities possess their own identity. Recently, Jonas Arenhart proposed a distinction of quantum objects in terms of a dilemma which forces a choice between their characterization either as individuals or as non-individuals. In this work we attempt to address the (metaphysical) presuppositions involved within Arenhart’s dilemma which ground the question of individuality in QM on a strong presupposition regarding the existence of quantum objects. After providing a reconsideration of the role played by metaphysics within physics we attempt to propose, not only a complete redefinition of the dilemma beyond particle metaphysics, but also a possible realist solution grounded on the provision of a new (non-classical) conceptual framework which seeks to develop an invariant-objective representation of the theory of quanta. Keywords: Quantum individuality, powers, indiscernibility. We are, to be sure, all of us aware of the situation regarding what will turn out to be the basic foundational concepts in physics: the point-mass or the particle is surely not among them.
