In this chapter, we will take a trip around several hot-spots where Bohmian mechanics and its capacity to describe the microscopic reality, even in the absence of measurements, can be harnessed as computational tools, in order to help in the prediction of phenomenologically accessible information (also useful for the followers of the Copenhagen theory). As a first example, we will see how a Stochastic Schrödinger Equation, when used to compute the reduced density matrix of a non-Markovian open quantum system, necessarily (...) seems to employ the Bohmian concept of a conditional wavefunction. We will see that by dressing these conditional wavefunctions with an interpretation, the Bohmian theory can prove to be a useful tool to build general quantum simulation frameworks, such as a high-frequency electron transport model. As a second example, we will explain how a Copenhagen “observable operator” can be related to numerical properties of the Bohmian trajectories, which within Bohmian mechanics, are well-defined even for an “unmeasured” system. Most importantly in practice, even if these numbers are given no ontological meaning, not only we will be able to simulate (thus, predict and talk about) them, but we will see that they can be operationally determined in a weak value experiment. Therefore, they will be practical numbers to characterize a quantum system irrespective of the followed quantum theory. (shrink)

We analyze the notion of guessing model, a way to assign combinatorial properties to arbitrary regular cardinals. Guessing models can be used, in combination with inaccessibility, to characterize various large cardinal axioms, ranging from supercompactness to rank-to-rank embeddings. The majority of these large cardinal properties can be defined in terms of suitable elementary embeddings j:Vγ→Vλ. One key observation is that such embeddings are uniquely determined by the image structures j[Vγ]≺Vλ. These structures will be the prototypes guessing models. We shall show, (...) using guessing models M, how to prove for the ordinal κM=jM) many of the combinatorial properties that we can prove for the cardinal j) using the structure j[Vγ]≺Vj. κM will always be a regular cardinal, but consistently can be a successor and guessing models M with κM=ℵ2 exist assuming the proper forcing axiom. By means of these models we shall introduce a new structural property of models of PFA: the existence of a “Laver function” f:ℵ2→Hℵ2 sharing the same features of the usual Laver functions f:κ→Hκ provided by a supercompact cardinal κ. Further applications of our analysis will be proofs of the singular cardinal hypothesis and of the failure of the square principle assuming the existence of guessing models. In particular the failure of square shows that the existence of guessing models is a very strong assumption in terms of large cardinal strength. (shrink)

Bruineberg and collaborators distinguish three philosophical positions about the status of Markov blankets in the context of active inference modelling, namely: literalism, realism, and instrumentalism. They criticize the first two positions and suggest that instrumentalism is “less problematic but also less interesting” (sect. 6.1.2, para. 5) Here, I sketch how literalists and realists might reply to Bruineberg et al.'s criticisms, and I explain why instrumentalism is more interesting and contentious than what Bruineberg and collaborators suggest.

In this paper we describe an experimental test of the validity of the Pauli Exclusion Principle (for electrons) which is based on a straightforward idea put forward a few years ago by Ramberg and Snow (Phys. Lett. B 238:438, 1990). We perform a very accurate search of X-rays from the Pauli-forbidden atomic transitions of electrons in the already filled 1S shells of copper atoms. Although the experiment has a very simple structure, it poses deep conceptual and interpretational problems. Here we (...) describe the experimental method and recent experimental results, which we interpret in the framework of quon theory. We also present future plans to upgrade the experimental apparatus using Silicon Drift Detectors. (shrink)

Il presente contributo intende proporre una considerazione critica dell’utilizzo del concetto di fine della storia proposto da F. Fukuyama. Pur soffermandosi sulla presunta genesi hegeliana della fine della storia e su una comparazione con il sistema di Hegel, l’obiettivo principale dell’articolo non è quello di offrire un’indagine filologica della lettura offerta da Fukuyama, ma, attraverso un confronto con la prospettiva interpretativa e filosofica di A. Kojève, quello di indagare l’origine politica della proposta di filosofia della storia delineata da Fukuyama e (...) di valutarne contraddizioni e criticità. (shrink)

We present the idea of searching for X-rays as a signature of the mechanism inducing the spontaneous collapse of the wave function. Such a signal is predicted by the continuous spontaneous localization theories, which are solving the “measurement problem” by modifying the Schrödinger equation. We will show some encouraging preliminary results and discuss future plans and strategy.

Special issue: "Reflecting on the Legacy of C.I. Lewis: Contemporary and Historical Perspectives on Modal Logic".

What are the conditions for holding each other responsible for the actions we take? What is moral blame and how does it function? Can we hold ourselves morally responsible for actions that depend on situational influences? Can growing up in unfortunate circumstances be a reason to suspend our blame attitudes? These are some of the questions that have characterized the contemporary debate on moral responsibility. Building on the reflections on responsibility proposed by Peter Strawson, the author reconstructs some attempts in (...) contemporary English-language moral philosophy to answer them. At the centre of inquiry there are the socalled "practices of moral responsibility", which divide two shores: the description of moral agents as natural agents and the normative expectations that generate reciprocal claims about respectful behavior.

In lieu of an abstract, here is a brief excerpt of the content:THE INCOMMUNICABILITY OF HUMAN PERSONS JOHN F. CROSBY, III Franciscan University of Steubenville Steubenville, Ohio I PROPOSE TO explore the idea that persons do not exist as replaceable specimens of or as mere instances of an ideal or type, but rather exist in some sense for their own sakes, each existing as incommunicably his or her own.1 I undertake this study in the conviction that the incommunicability of persons (...) is profoundly characteristic for them precisely as persons, and has a major role to play in any philosophy of the person. And there is an entirely different reason which attracts me to this subject. I think that most of what I have to say here can find acceptance across a broad spectrum of philosophical positions. At a time when thinkers are increasingly suspicious of universally valid truth about man, when many of them think that a vision of man is proper only to some tradition and valid only within that tradition and not beyond it, one can offer a salutary challenge to one's contemporaries by showing a centrally important truth about persons which, as I say, can be accepted by philosophers coming from the most various points of view. Suppose that you were to minimalize the death of someone by saying that at least the human species did not die with him or her, as if the immortality of the species more than compensated for the mortality of this individual : everyone understands that you would thereby radically depersonalize the deceased. Or suppose that you were grieving over the death of someone dear to you, and a friend tried to comfort you with the thought that the 1 My thanks to Josef Seifert, William Frank, Damian Fedoryka, and Katryna Fedoryka for their comments on earlier drafts of this study.

CROSBY, III particular excellences of the deceased, which awakened your love, also exist in other human beings who are still living, as if you could continue to love in them what you had loved in the deceased. Again, everyone understands that if you treat people having excellences as if they were replaceable specimens of those excellences, then you lose your grip on them as persons. But why is this? Why is personhood driven out of human beings as soon as their species-membership, or their particular excellences, are thought to predominate in them? What is that incommunicability of each person which is obscured as soon as persons are thought to be only specimens? One commonly thinks that this aspect of personal selfhood has been recognized only in modern thought; in fact it was recognized already by St. Thomas Aquinas. Creatura autem rationalis divinae providentiae substat sicut secundum se gubernata et provisa, non solum propter speciem, ut aliae corruptibiles creaturae : quia individuum quod gubernatur solum propter speciem, non gubernatur propter seipsum; creatura autem rationalis propter seipsam gubernatur, ut ex dictis manifestum est. Sic igitur solae rationales creaturae directionem a Deo ad suos actus accipiunt non solum propter speciem, sed secundum individuum.2 Notice that Aquinas teaches here the metaphysical ultimacy of personal incommunicability; it exists even before God in the sense 2 " Now, a rational creature exists under divine providence as a being governed and provided for in himself, and not simply for the sake of his species, as is the case with other corruptible creatures. For the individual that is governed only for the sake of the species is not governed for its own sake, but the rational creature is governed for his own sake, as is clear from what we have said (ch. 112). And so, only rational creatures receive direction from God in their acts, not only for the species, but for the individual." Summa Contra Gentiles, III, ch. 113 (Bourke translation). By the way, Chapters 111-114 of Book III seem to me to constitute the most " personalist " passage' in the entire corpus of St. Thomas. The modern reader sees to his amazement that St. Thomas here has already made his own the Kantian idea that each person in a sense exists for his... (shrink)

The defining principle of evolutionary biology is that all species, extant and extinct, evolved from ancient prokaryotic cells. Their initial appearance and adaptive evolution are proposed to have been accompanied by a cellular sentience, by feelings, subjectivity or, in a word, 'consciousness'. Prokaryotic cells, such as archaea and bacteria, have natural unitary, valence-marked 'mental' representations. They process and evaluate sensory information in a context-dependent manner. They learn, establish memories, and communicate using biophysical fields acting on excitable membranes. Symbiotic eukaryotic cells, (...) which evolved much later, initiated a compound cellular subjectivity utilizing 'senomic' and 'ephaptic' principles that evolved into the varieties of consciousness seen in multicellular species. This Cellular Basis of Consciousness (CBC) model provides a novel framework within which to approach fundamental issues such as the origins of life and the emergence of mind. (shrink)

Political ecology is one of the most vibrant fields of environmental research. This book introduces political ecology to a new generation of students in a daring new way: as an interdisciplinary approach to environmental research but also as a series of lived realities and a praxis for change. The origins of political ecology are often traced through an Anglo-American canon. In Discovering Political Ecology, Gustav Cederlöf and Alex Loftus instead take up the challenge of presenting the key conversations and the (...) diverse traditions that have shaped this field with attention to its extensive international roots. Inspired by voices and research in Asia, Africa, Europe and the Americas, the authors address the concerns of those who from different social backgrounds have grown up in a world shaped by climate change and increasing environmental inequalities.Engaging and accessible in style, Discovering Political Ecology introduces a set of key concepts around which conversations in political ecology coalesce. It also shows how these concepts allow you to make sense of some of the most pressing issues of our time-issues around water, energy, agriculture, forestry, climate change and environmental justice. Each chapter includes learning outcomes and suggested further readings, extensive bibliographies and seminar activities to be used by students and educators. At the cutting-edge of the field, the book will be of interest to those in all disciplines brought together in political ecology, including but not limited to anthropology, development studies, ecology, geography, history and political science.

From the time of the thinkers of ancient Greece, the question of what can be said about the existence and nature of God has been debated by many philosophers and theologians. In Theism and Atheism: The Eternal Debate, F.F. Centore presents a broad analysis of the major positions that address the question and the thinkers who have contributed to the debate. This is an admirably lucid and thorough examination of the history of natural theology. Covering the material in a thematic (...) rather than in a strictly chronological way, Centore draws out the key positions on topics such as the relationship of science and religion, the problem of evil, Naturalistic and Supernaturalistic theism and the dispute between essence and existence. The proponents of the various positions are considered alongside their most explicit critics. Important thinkers dealt with in this work include Plato, Aristotle, Aquinas, Descartes, Pascal, Kant, Hume, Hegel, Nietzsche, Freud and Darwin. The diversity of exploration also goes beyond the Judeo-Christian tradition to look at Hinduism, Buddhism, Stoicism, Zoroastrianism, Confucianism and Classical Paganism. This work, however, is much more than a survey of the major historical arguments and rebuttals concerning God's existence and nature. Overall, it is a work by a well-established Catholic philosopher who concludes that God's existence and nature are indeed compatible with modern science, human freedom and the existence of evil in the world.

Portraits of Wittgenstein is a major collection of memoirs and reflections on one of the most influential and yet elusive personalities in the history of modern philosophy, Ludwig Wittgenstein. Featuring a wealth of illuminating and profound insights into Wittgenstein's extraordinary life, this unique collection reveals Wittgenstein's character and power of personality more vividly and comprehensively than ever before. With portraits from more than seventy-five figures, Portraits of Wittgenstein brings together the personal recollections of philosophers, students, friends and acquaintances, including Bertrand (...) Russell, G. E. Moore, F. R. Leavis, A. J. Ayer, Karl Popper, Friedrich von Hayek, G. H. von Wright, Rush Rhees, Freeman Dyson, G. E. M. Anscombe, Iris Murdoch, Mary Midgley and Mary Warnock. These authors testify to the life-long influence Wittgenstein had on the lives of those he met. Their fascinating memoirs, reflections and commentaries, often at odds with each other, reveal Wittgenstein's kindness, and how much genuine friendship meant to him, as well as his suffering and despair. They show too how the philosopher's ruthless honesty and uncompromising integrity often resulted in stern advice and harsh rebukes to friends and foes alike. Now available in a single, revised and updated volume, Portraits of Wittgenstein includes new selections, revised contributions, photographs, maps and introductory overviews that provide historical context to Wittgenstein's relationships with his intellectual and social circle. This collection of valuable and hard-to-find material is an indispensable resource for scholars and students of the life and work of Ludwig Wittgenstein. (shrink)

Bredo C. Johnsen: Observation: What Quine calls observation sentences lie at the heart of his reflections on observation and its roles in prompting our theorizing, providing evidence for our theories, and serving as the test of those theories' truth. The first four sections of this chapter – “Observation sentences,” “The two types of observation sentence,” “Introspection,” and “Roles of experience” – are devoted to expounding and clarifying his fundamental conception of these sentences, showing that he recognized both objective and subjective (...) observation sentences, that correlatively he gives introspection an important place in our cognitive lives, and, in particular, that he assigns our introspective knowledge of our sensory experiences three important roles in his epistemology. Since about 1970, Quine's conception of what constitutes our evidence about the nature of empirical reality has been radically misunderstood by almost all his readers, with disastrous consequences for the understanding of his entire epistemology; a final section – “Stimulations as evidence” – is therefore devoted to remedying this situation.

This paper focuses on the categoricity of arithmetic and determinacy of arithmetical truth. Several ‘internal’ categoricity results have been discussed in the recent literature. Against the background of the philosophical position called internalism, we propose and investigate truth-theoretic versions of internal categoricity based on a primitive truth predicate. We argue for the compatibility of a primitive truth predicate with internalism and provide a novel argument for (and proof of) a truth-theoretic version of internal categoricity and internal determinacy with some positive (...) properties.

The notion of causal evidence in medicine has been the subject of wide philosophical debate in recent years. The notion of evidence has been discussed mostly in connection with Evidence Based Medicine and, more in general, with the assessment of causal nexus in medical, and especially research contexts. “Manipulative evidence” is one of the notions of causal evidence that has stimulated much debate. It has been defined in slightly different ways, attributed different relevance, and recently placed at the core of (...) Gillies’ “action-related theory of causality”, a view specifically meant to address causation in medicine. While in general sympathetic to Gillies’ account, and totally convinced of the relevance of manipulative evidence and different sorts of interventions in the biomedical sciences, we believe that some further qualifications are needed to allow the notion of manipulative evidence to better express features of medical practice. In particular, we provide some qualification of the role of “interventional evidence” proposed by Gillies, suggesting a distinction between “interventional evidence” and “evidence for interventions”. A case study from research on rare diseases is analyzed in depth and a multifaceted notion of manipulative evidence put forward that allows better understanding of what manipulations in medical contexts amount to and what their targets are.

In Practicing Safe Sects F. LeRon Shults provides scientific and philosophical resources for having “the talk” about religious reproduction: where do gods come from – and what are the costs of bearing them in our culturally pluralistic, ecologically fragile environment?

A morally perfect God necessarily desires that all rational agents behave morally. An omnipotent and omniscient God has the power and knowledge to ensure that all rational agents have sufficient moral knowledge to do what morality requires. So, if God exists, there are no rational moral agents who lack sufficient moral knowledge to act morally. However, there has been a wide range of moral agents who, without blame, have lacked the moral knowledge to behave morally. Therefore, God does not exist. (...) The preceding argument from non-blameable moral ignorance of our fundamental moral obligations is resistant to some of the standard theistic responses to the problem of evil and divine hiddenness. Moreover, some of the standard theistic responses to the traditional arguments for God’s non-existence lend support to the argument from blameless moral ignorance. (shrink)
