The property of fundamental mechanical theories which allows one to treat compound objects as particles under suitable conditions is considered. It is argued that such a property, called composition invariance, is a nonreleasable property of any fundamental mechanical theory. The proof that standard quantum mechanics enjoys composition invariance is reviewed. Finally, it is shown that the requirement of composition invariance allows one to choose between two alternative forms of quantum mechanics with spontaneous localization.

Two different kinds of stochastic processes in Hilbert space used to introduce spontaneous localization into the quantum evolution are investigated. In the processes of the first type, finite changes of the wave function take place instantaneously with a given mean frequency. The processes of the second type are continuous. It is shown that under a suitable infinite frequency limit the discontinuous process transforms itself into the continuous one.

The property of fundamental mechanical theories which allows to treat compound objects as particles under suitable conditions is considered. It is argued that such a property, called compoundation invariance, is a nonreleasable property of any mechanical theory not declaring to which elementary constituents it applies. Compoundation invariance is discussed in the framework of Bohmian mechanics. It is found that standard Bohmian mechanics satisfies the requirement of compoundation invariance, with some reservation in the case of compound objects with spin. On the (...) contrary that requirement is violated when additional terms are added to the standard velocity. (shrink)

A new proposal for a Lorentz-invariant spontaneous localization process in the framework of relativistic quantum field theory is presented. As in all dynamical reduction models, a stochastic process is introduced, which drives the state vector towards the eigenspaces of a set of operators representing suitably chosen physical quantities. Such operators constitute a Lorentz scalar field and are built as time averages and space integrals of a local field-theoretic operator in such a way that the quantities they represent acquire a macroscopic (...) character. As always in dynamical reduction theories, the action of the process on microscopic systems takes place via the micro-macro correlations which arise, e.g., as a consequence of measurements. (shrink)

In the framework of the history approach to quantum mechanics and, in particular, of the formulation of Gell-Mann and Hartle, the question of the existence of inequivalent decoherent sets of histories is reconsidered. A simple but acceptably realistic model of the dynamics of the universe is proposed and a particular set of histories is shown to be decoherent. By suitable tranformations of this set, a family of sets of histories is then generated, such that the sets, first, are decoherent on (...) the basis of the assumed dynamics of the universe and, secondly, arc certainly inequivalent, apart from trivial special cases. Finally, the original set of histories is refined to get a model of the usual quasiclassical domain and it is shown that, applying to it the previously considered transformations, a family of sets of histories is obtained which share typical properties of the usual quasiclassical domain.

El objetivo de este artículo es clarificar la noción de «vida auténtica» tal y como es descrita por Joan Roura-Parella en su última obra Tema y variaciones de la personalidad (1950). Por «vida auténtica» se entiende una vida autogobernada, que permite al individuo realizar su propia singularidad y, por tanto, preservar su autonomía y dignidad como persona. Una vida dominada por factores ajenos al propio individuo, sean cuales sean éstos, es una vida alienada, que no permite el desarrollo del individuo (...) en tanto la persona que es. Se señala la relevancia filosófica de la propuesta de Roura-Parella, que es la de ofrecer una justificación no-evidencial para una forma de vida cristiana, agapística. De acuerdo con Roura-Parella, una forma de vida basada en la entrega amorosa para con el prójimo está justificada en tanto que ésta es el resultado último de nuestra propia condición natural, constituyendo así un acto de afirmación personal y siendo, por tanto, condición necesaria para gozar de una vida auténtica — «la vida alcanza su hondo sentido al salirse de sí misma para darse a los demás» (Roura-Parella, Tema y variaciones de la personalidad, 1950, p. 229). Se señalan las diferencias y semejanzas de la propuesta de Roura-Parella con respecto a las de Miguel de Unamuno y Joaquim Xirau, autores que fueron cercanos a Roura-Parella y quienes, aunque partiendo de razonamientos distintos a los de Roura-Parella, también concibieron la entrega amorosa para con el prójimo como un acto de afirmación personal.

In this paper I argue for a syncretistic theory of depiction, which combines the merits of the main paradigms which have hitherto faced themselves on this issue, namely the perceptualist and semioticist approaches. The syncretistic theory indeed takes from the former its stress on experiential factors and from the latter its stress on conventional factors. But the theory is even more syncretistic than this, for the way it accounts for the experiential factor vindicates several claims defended by different perceptualist theories. (...) In a nutshell, according to the syncretistic theory a picture depicts its subject iff i) it is transformed into an entity-cum-meaning and ii) one has the twofold experience of seeing that subject in the picture qua noninterpreted entity, the image, just in case one consciously misrecognizes it in consciously seeing that image, for that subject resembles the image in some grouping properties (originally labelled Gestalt-qualities in psychology). By appealing to objective resemblance in grouping properties, the theory can vindicate what are nowadays taken to be the most neglected doctrines in the perceptualist camp: objective resemblance theories. By appealing, moreover, to conscious misrecognition, the theory not only squares with both the seeing-in and the recognition theories of depiction, but it also shows the grain of truth in illusion theories of depiction, since conscious misrecognition is a kind of perceptual illusion.

El objetivo de este artículo es explorar la manera en que Joaquim Xirau y Miguel de Unamuno concibieron el amor. A pesar de que no hay motivos suficientes para concluir una influencia directa y filosóficamente relevante de Unamuno en la obra de Xirau, sí podemos concluir que la forma en que ambos autores concibieron el amor guarda ciertas similitudes. Así, ambos coinciden en concebir la entrega amorosa como un ejercicio de afirmación individual que trae consigo un incremento de la propia (...) singularidad. También, tanto Unamuno como Xirau conciben la entrega amorosa como un acto que, aun surgiendo del propio individuo y no de como es de hecho el mundo, personifica aquello amado, dejando de ser así visto como un mero objeto y mostrándose bajo una forma personal. Y ambos, aunque de un modo distinto, hacen del relato bíblico acerca de la vida y Resurrección de Cristo un aspecto central de sus maneras de entender el amor. (shrink)

The aim of this chapter is to analyse the concept of love —understood in the broad and Christian-inspired sense of love as agape-charis love— in relation to the animes Dragon Ball and Dragon Ball Z. I first comment on the character of Piccolo —and how his friendship with Son Gohan— leads to him losing all his original villainous traits. I argue that the evolution of the character of Piccolo through his friendship with Son Gohan illustrates the philosophical claim that a (...) loving and giving of oneself to the other —far from being a sign of weakness— is a courageous and self-affirming exercise. The result may move the individual to an inner transformative experience that leads to the enjoyment of a renewed and authentic life that is worth living. I then argue that Son Goku’s respectful attitude towards his opponents is ultimately a loving attitude. Last, I argue that it is the inspiring and loving example of Son Goku that ultimately explains why characters such as Vegeta —who are at first presented as villains— end up losing their villainous traits after fighting against Son Goku.

En este artículo expongo y analizo la propuesta berkeleyana del conocimiento nocional, que representa entre otras cosas el intento del irlandés por conocer a la mente o espíritu, esto es, a aquella cosa pensante y activa que por su propia actividad resulta irrepresentable como idea. Como el conocimiento nocional ya se menciona en los Comentarios Filosófi cos me remitiré a ellos para conocer los orígenes del mismo; sin embargo, como tal conocimiento aparece con mayor detalle en obras posteriores me serviré (...) sobre todo del Tratado para abordar la compleja doctrina nocional. // In this paper I expose and analyze the berkeleian proposal of notional knowledge. Among other things, this proposal represents Berkeley ́s attempt to know the mind or spirit, that is, the thinking and active thing that by its own activity results unrepresentable as idea. As such knowledge is already mentioned in the Philosophical Commentaries, I will refer to them in order to know the origins of that proposal. However, as notional knowledge appears in more detail in later works, I will make use especially of the Treatise to address the complex notional doctrine. (shrink)

In Ockhamist branching-time logic [Prior 67], formulas are meant to be evaluated on a specified branch, or history, passing through the moment at hand. The linguistic counterpart of the manifoldness of future is a possibility operator which is read as `at some branch, or history (passing through the moment at hand)'. Both the bundled-trees semantics [Burgess 79] and the $\langle moment, history\rangle$ semantics [Thomason 84] for the possibility operator involve a quantification over sets of moments. The Ockhamist frames are (3-modal) (...) Kripke structures in which this second-order quantification is represented by a first-order quantification. The aim of the present paper is to investigate the notions of modal definability, validity, and axiomatizability concerning 3-modal frames which can be viewed as generalizations of Ockhamist frames.

This book develops a novel theory of intentionality. It argues that intentionality is an internal essential relation of constitution between an intentional state and an object or between such a state and a possible state of affairs as subsisting. The author's main claim is that intentionality is a fundamentally modal property, hence a non (scientifically) natural property in that it does not supervene, either locally or globally, on its nonmodal physical basis. This is the property, primarily for an intentional mental (...) state, to be constituted by the entities it is about. In the case of intentionality of reference, such constituents are objects, in the sense of individuals; in the case of intentionality of content, such constituents are possible states of affairs as subsisting. Constitution is meant in a mereologically literal sense: those constituents are essential parts of the relevant states. As a result, the theory claims not only that intentionality is relational, but also that is an internal, essential relation holding between an intentional state and its object or proposition-like content. Intentionality as Constitution will be of interest to scholars and advanced students working in philosophy of mind, philosophy of language, metaphysics, and cognitive science. (shrink)

Unamuno saw in his defense of religious faith a response to Nietzsche’s criticisms of the Christian, agapeic way of life. To Nietzsche’s claim that engaging in this way of life is something antinatural and life‐denying, insofar as it goes against the (alleged) natural tendency to increase one’s own power, Unamuno responded that an agapeic way of life is precisely a direct expression of this natural tendency. Far from being something that goes against our natural inclinations, Unamuno says, an agapeic way (...) of life is a life‐affirming exercise, something we are led to given our own natural condition. Hence, the aim of this essay is to comment on Unamuno’s criticism of Nietzsche and to point out the philosophical relevance of Unamuno’s attempt to provide a natural foundation for religious faith when assessing Nietzsche’s criticisms of the possibility of carrying out a Christian, agapeic way of life.

Character plays a central role in our everyday understanding and evaluation of ourselves and one another. It informs the expectations that ground our plans and projects, our moral responses to other people's behaviour and to opportunities we ourselves face, and our political decisions concerning formal education, criminal punishment, and other aspects of social organisation. These philosophical essays clarify this idea of character, analyse its relation with the findings of experimental psychology, and draw out the implications of this for education and (...) for criminal punishment. They emphasise that character is inherently dynamic, challenging the tendency among personality psychologists and virtue ethicists alike to focus on static snapshots of traits, and they emphasise the close integration of character with the individual's social context. The volume is intended to demonstrate the deep conceptual affinity of moral philosophy and social psychology and the consequent potential for each to benefit from the other. (shrink)

A completeness theorem is established for logics with congruence endowed with general semantics (in the style of general frames). As a corollary, completeness is shown to be preserved by fibring logics with congruence provided that congruence is retained in the resulting logic. The class of logics with equivalence is shown to be closed under fibring and to be included in the class of logics with congruence. Thus, completeness is shown to be preserved by fibring logics with equivalence and general semantics. (...) An example is provided showing that completeness is not always preserved by fibring ligics endowed with standard (non general) semantics. A categorial characterization of fibring is provided using coproducts and cocartesian liftings. (shrink)

This open access book discusses individual, collective, and institutional responsibilities with regard to vaccination from the perspective of philosophy and public health ethics. It addresses the issue of what it means for a collective to be morally responsible for the realisation of herd immunity and what the implications of collective responsibility are for individual and institutional responsibilities. The first chapter introduces some key concepts in the vaccination debate, such as ‘herd immunity’, ‘public goods’, and ‘vaccine refusal’; and explains why failure (...) to vaccinate raises certain ethical issues. The second chapter analyses, from a philosophical perspective, the relationship between individual, collective, and institutional responsibilities with regard to the realisation of herd immunity. The third chapter is about the principle of least restrictive alternative in public health ethics and its implications for vaccination policies. Finally, the fourth chapter presents an ethical argument for unqualified compulsory vaccination, i.e. for compulsory vaccination that does not allow for any conscientious objection. The book will appeal to philosophers interested in public health ethics and the general public interested in the philosophical underpinning of different arguments about our moral obligations with regard to vaccination.

In just the last decade, many conference proceedings have been published on Plato’s Timaeus and its influence on the history of philosophy. The present vo­lume, which is the result of a symposium held at Seoul National University in September 2011, testifies to the enduring and widespread interest the Platonic dia­logue is able to elicit. The nine studies here collected by Euree Song center on the figure of the demiurge as maker of the world and they all deal with authors who, (...) while having di... (shrink)

Both landscape and aesthetics are all too often considered disengaged categories associated with leisure and contemplation. This book establishes landscape as a key concept in contemporary thought and rethinks aesthetics in political and activist terms. In order to do so, it challenges the dualism of "the environment" as the space inhabited by humans and the province of the natural sciences about which philosophy has little to say. (This separation is evident even in the name of the recent field of environmental (...) humanities.) In a holistic view, landscapes are at the intersection of environment and human, place and people, and nature and culture, and aesthetics provide an immersive and engaged approach to them. Landscapes are ways of being in the world and aesthetics practical means of inhabiting them. Utilizing a pragmatist, antiessentialist lens, Alberto L. Siani characterizes landscapes (as opposed to environments and territories) as concrete, experienced habitats, performative ways of making sense of the world, while aesthetics (following Dewey) identify values and ordering criteria that permeate them. He addresses issues such as temporality, environmentalism, justice, education, and interdisciplinarity within this framework and in conversation with scientific positions. A coda gives three phenomenological accounts of intensely experienced and inhabited landscapes. (shrink)

Berkeley’s immaterialist philosophy has been frequently underestimated as a result of the misunderstanding of his ontological proposal, specifically because of the complexity of his concept of idea. The aim of this paper is then to clarify and explain that concept because from it depends the correct understanding of Berkeley’s ontological and immaterialist proposal. To do this, 1) I will show some examples of the misunderstanding that the berkeleian proposal has had, mainly due to his concept of idea; 2) I will (...) track how this notion was being developed in Berkeley’s early notes, known as Philosophical Commentaries; 3) I will analyze and explain the concept of idea from the published work of Berkeley, that is, from the Principles and Dialogues. -/- La filosofía inmaterialista de Berkeley ha sido muchas veces infravalorada por la mala comprensión de su propuesta ontológica, específicamente por la dificultad que presenta su concepto de idea.

Para realizar esto 1) mostraré algunos ejemplos de la mala comprensión que ha tenido la propuesta berkeleyana, debido principalmente a su concepto de idea; 2) rastrearé cómo se fue conformando dicho concepto en las notas de juventud conocidas como Comentarios Filosóficos; 3) analizaré y explicaré el concepto de idea a partir de la obra publicada de los Principios y los Diálogos.

The Yoga Sutras of Patanjali is the classic Hindu text on the spiritual practice of yoga. Written more than 2,000 years ago, these teachings provide a rich, contemplative understanding of yoga and philosophy. In this book, best-selling author and shaman Alberto Villoldo reveals how these teachings are available to us at all times-without gurus, temples, or decades of study. Villoldo's own fieldwork with the high shamans of the Americas has shown that the goals of shamanism and yoga are identical, (...) and he demonstrates the parallels in their practices. In a series of short, inspirational passages from the Sutras, the reader is led toward self-realization and enlightenment in its simplest form. In this treasured book, Villoldo brings to life the spiritual teachings of yoga in a pure and practical way--stripped of dogma and brimming with poetry and spirit."--Page 4 of cover. (shrink)
