En las actividades ordinarias de nuestra vida cotidiana encontramos nuestros actos de percepción confrontados por las cosas materiales. A ellos ─actos de percepción─ les atribuimos una existencia "real" asumiéndolos de tal manera que los sumergimos y transfundimos, de forma múltiple e indefinida, dentro del entorno de realidades análogas que se unen para formar un único mundo al que yo, con mi propio cuerpo, pertenezco. Ahora bien sí frente a la cotidianidad descrita anteriormente asumimos una actitud escéptica acerca de lo que (...) es “real” en el mundo,nos descubriremos haciendo una reflexión filosófica. Bajo esta deliberación encontramos que, por ejemplo, la cualidad "verde", tiene existencia por medio de la sensación "verde"asociada a un objeto dado por la percepción, lo que nos lleva a pensar que no tiene sentido vincularla sensación como cosa en sí misma a cosas materiales existentes en sí mismos , esto nos lleva a pensar que las cualidades de los sentidostienen carácter subjetivo.A pesar de esta reflexión es conveniente acotar que esta subjetividad no interesaa las ciencias exactas ya que éstas procuran lo objetivo. -/- Desde este punto de vista,encontramos dentro de los estudios de Galileo Galilei el principio que subyace al método matemáticoconstructivo de nuestra física moderna ; de esta manera, y bajo este principio,los colores ─ por ejemplo “verde”─ son solo vibraciones en un medio repudiando de esta forma el carácter subjetivo a la vez que se mantiene la objetividad. Sin embargo, dentro del campo de la filosofía el idealismo transcendental de Kant marca un cambio de paradigma en relación a lo anterior. Kant sostiene que no solamente las cualidades de los sentidos tienen carácter subjetivo, sino que espacio y tiempo, conceptos fundacionales dentro de la física, no tienen significación absoluta; en otras palabras, espacio y tiempo son formas de nuestra percepción . Para Kant aquello que sustenta nuestra percepción y aquello que sustenta el conocimiento matemático aplicado a la experiencia son lo mismo: intuiciones puras a priori del espacio y el tiempo. De esta manera, y bajo esta perspectiva, sólo la teoría de la relatividad deja muyen claro que las dos esencias: espacio y tiempo, como formas de la intuición en términos kantianos, no tienen lugar en el mundo construido por la física matemática concebida por Galileo . -/- Según esto, los colores no son siquiera vibraciones en un medio sino simplemente una serie de valores de funciones matemáticas en las que se producen cuatro parámetros independientes que corresponden a las tres dimensiones del espacio y la del tiempo, expresado como principio general esto significa que el mundo real y cada uno de sus constituyentes con sus características sólo pueden ser, en términos husserlianos, objetos intencionales de actos de conciencia . En otras palabras: los datos inmediatos que recibo son las experiencias de la conciencia. Esto nos permite afirmar que la sensación de un objeto está presente de una forma físicamente real para mí con quien esa sensación se relaciona. Esto es lo que Brentano llama objeto intencional ;es así como al percibir un objeto, por ejemplo: veo este “libro” mi atención está totalmente dirigida hacia él. Yo "tengo" la percepción, pero sólo cuando hago de esta percepción ─ acto libre de reflexión ─algo que "conozco" con respecto a ella ─y no sólo el “libro”─ llego precisamente a un segundo acto: objetos intencionales de actos de conciencia, que son a los que referíamos antes . -/- El objeto intencional es inmanente y lo que es inmanente es absoluto ; es exactamente lo que es en la forma en que lo tengo, y puedo reducir esto, su esencia, por los actos de reflexión . En otras palabras, es un componente real de mis experiencias; contrario a lo que sucede con el acto primario de percepción, donde el objeto es trascendental , esto es, se da en una experiencia de conciencia pero no es un componente real de la misma. Por otra parte, los objetos trascendentales tienen sólo una existencia fenoménica; son apariencias que se presentan de múltiples maneras. Ninguno de estos modos de aparición puede pretender presentar aquello que percibimos – por ejemplo el libro- tal como es en sí, además en toda percepción está involucrada la tesis de la realidad del objeto que aparece en ella; este último es, de hecho, un elemento fijo y duradero de la tesis general de la realidad del mundo . En resumen, lo que interesa ver claramente es la importancia enel dato de la conciencia como punto de partida en el que debemos situarnos si queremos comprender el significado absoluto . (shrink)

Physical education is often justified within the curriculum as academic study, as a worthwhile activity on a par with other academic subjects on offer and easy to assess. Part of the problem has been that movement studies in physical education are looked upon as disembodied and disconnected from its central concerns which are associated with employing physical means to develop the whole person. But this, Merleau-Ponty would say, is to ignore the nature of experience and to consider the cognitive aspects (...) of our perceptual experience in isolation from the personal meaning gained when looked at from the ?inside? or participatory perspective of the moving agent. In this sense, physical education has lost meaning for some students because our embodied relationship with the world is not an external or contemplative one. Phenomenology, according to Merleau-Ponty, is significant for physical education because it highlights what it is like to be embodied and recognises the role corporeal movement and embodiment plays in learning, in, by and through physical education. What makes this account educationally significant for physical education is that the whole person should benefit by the experience, as it includes an emphasis on all three educational domains (the psychomotor, the cognitive and the affective), rather than as separate physical and mental qualities that bear no relation to each other.

My thesis tests a novel definition of consciousness by applying it to theories of self-consciousness. This definition attempts to distinguish the phenomenon of consciousness from those of knowledge, belief, awareness, and perception by describing it as the noticing of objects and the registering of facts in thought. My investigation of self-consciousness is phenomenological in that it leaves aside questions as to whether selves exist or what their nature is and just examines what the contents of self-consciousness are. The main (...) question, throughout the thesis, is whether there are any contents that necessarily enter self-consciousness understood as consciousness associated with meaningful use of the first personal pronoun. My answer to this question is that there are not. This answer is reached after the discussion of a range of prominent theories that have emanated from Kant. All these theories have in common that they can be phenomenologically clarified with the help of my description of consciousness. Kant’s own views of “empirical self-consciousness” are phenomenologically relatively modest; but what he says about “transcendental self-consciousness”, incorporating a priori consciousness of one’s identity, cannot be phenomenologically supported. Similar restrictions apply to Fichte’s theory, which develops the notion of transcendental self-consciousness, explicating it as consciousness of “this very consciousness”. Strawsonian theories of self-consciousness (P.F. Strawson, G. Evans, Q. Cassam) claim that self-consciousness requires some awareness of oneself as a spatiotemporally located physical object. I argue that such a claim cannot be phenomenologically substantiated. The Strawsonian theories rely on a questionable “discrimination requirement”; but even if it is assumed that they are justified in claiming that, as self-conscious beings, we have to know, believe, perceive or be aware that we are physical objects, it still does not follow that we have to be conscious, in my sense, of ourselves as such objects. There is no particular type of object that is necessarily noticed and no particular type of fact that is necessarily registered in thought by a person who can meaningfully use the first personal pronoun. In the last part of the thesis, some of the results of the earlier chapters are applied to the problem of how to explain first person authority and an explanation which is compatible with those results is suggested.

This paper lays the groundwork for developing a thorough-going phenomenological description of different phenomena of violence such as physical, psychic and structural violence. The overall aim is to provide subject-centered approaches to violence within the social sciences and the humanities with an integrative theoretical framework. To do so, I will draw primarily on the phenomenological accounts of Maurice Merleau-Ponty and Alfred Schutz, and thereby present guiding clues for a phenomenologically grounded theory of violence.

Phenomenalism, Phenomenology and the Question of Time: A Comparative Study of the Theories of Mach, Husserl, and Boltzmann explores comparative analysis of the concept of phenomenology in relation to Mach’s, Boltzmann’s and Husserl’s works on time. It also explores whether or not phenomenology can be naturalized and the scope of its relation to the question of time, experience, physical processes, and irreversibility.

This article was originally Lai drunk leaves professor in 1994 year March 12 to 27 at Fu Jen Catholic University Department of Philosophy lecture on "Philosophy of Science" theme when the speech of course, today is led by Professor Shen-ching translated into Chinese to satisfy the readers. Speeches, the Lai drunk leaves professor from the phenomenological approach explore and rebuild "it" concept formation of thought processes, and especially from the physics theory in future test volume of this (...) issue, that the physics of the novel is that it is in theory integrated into the transcendental appearance regardless above, and thus different concepts in general regardless of the theory described. For him, physics theory although the use of purely abstract terms, but it still gives the specific physical presentation, try The arguments are purely ideal state, reflecting the world to open the actual Field of obvious things. He eventually proposed and therefore, physics can be interpreted as a phenomenological manifestation of Planning and its integration of theoretical representation regardless transcendental state, to give a physical reality now. This is a speech on physical reality delivered by Jean Ladrière in a series of talks related to philosophy of science during his visit to the Department of Philosophy, Fu Jen Catholic University from March 12 to March 27, 1994. Here it is translated into Chinese by Prof. Vincent Shen to exemplify an aspect of his philosophy. This paper attempts to reconstitute the process of thought by which the concept of reality is constructed and to consider it under the perspective of physics. For Jean Ladrière, the originality of physics is to integrate the transcendental discourse into its theoretical representation. All in using abstract terms, physical theories show us what happens effectively in the field of world manifestation. He would suggest that physics can be interpreted as a phenomenological project to make effective physical reality by integrating a transcendental discourse into its theoretical representation.

Solitons, i.e. solitary localized waves with particle-like behaviour, and multi-solitons occur virtually everywhere. There is a good reason for that in that there is a solid, albeit somewhat heuristic argument which says that for wave-like phenomena the 'soliton approximation' is the next one after the linear one. It is also not too difficult via some searching in the voluminous literature - many hundreds of papers on solitons each year - to write down a long list of equations which admit soliton (...) solutions and which model phenomena ranging over all the physical, biological, chemical and geological sciences as well as engineering. Yet, when lecturing on (mathematical) aspects of solitons I have found it not so easy to go beyond listing these equations. Largely because of lack of a book like this, which discusses where and how solitons arise, how they behave, whether or not they are stable and in what sense, which discusses approximate solitons and solitons in multidimensional spaces (which in a first simple natural formulation cannot exist), which discusses soliton (computer) experiments; all this for a wide range of phenomena especially in connection with solid state physics. There is a great deal of analytic material as well as there is especially a considerable collection of challenges for theoretical understanding. A great deal of the material covered in this book has not appeared in the monographic literature before. The phenomenology of solitons is very rich indeed. (shrink)

Measurement is said to be the basis of exact sciences as the process of assigning numbers to matter (things or their attributes), thus making it possible to apply the mathematically formulated laws of nature to the empirical world. Mathematics and empiria are best accorded to each other in laboratory experiments which function as what Nancy Cartwright calls nomological machine: an arrangement generating (mathematical) regularities. On the basis of accounts of measurement errors and uncertainties, I will argue for two claims: 1) (...) Both fundamental laws of physics, corresponding to ideal nomological machine, and phenomenological laws, corresponding to material nomological machine, lie, being highly idealised relative to the empirical reality; and also laboratory measurement data do not describe properties inherent to the world independently of human understanding of it. 2) Therefore the naive, representational view of measurement and experimentation should be replaced with a more pragmatic or practice-based view.

This thesis studies collider phenomenology of physics beyond the Standard Model at the Large Hadron Collider (LHC). It also explores in detail advanced topics related to Higgs boson and supersymmetry - one of the most exciting and well-motivated streams in particle physics. In particular, it finds a very large enhancement of multiple Higgs boson production in vector-boson scattering when Higgs couplings to gauge bosons differ from those predicted by the Standard Model. The thesis demonstrates that due to the (...) loss of unitarity, the very large enhancement for triple Higgs boson production takes place. This is a truly novel finding. The thesis also studies the effects of supersymmetric partners of top and bottom quarks on the Higgs production and decay at the LHC, pointing for the first time to non-universal alterations for two main production processes of the Higgs boson at the LHC-vector boson fusion and gluon-gluon fusion. Continuing the exploration of Higgs boson and supersymmetry at the LHC, the thesis extends existing experimental analysis and shows that for a single decay channel the mass of the top quark superpartner below 175 GeV can be completely excluded, which in turn excludes electroweak baryogenesis in the Minimal Supersymmetric Model. This is a major new finding for the HEP community. This thesis is very clearly written and the introduction and conclusions are accessible to a wide spectrum of readers. (shrink)

Analogue Gravity Phenomenology is a collection of contributions that cover a vast range of areas in physics, ranging from surface wave propagation in fluids to nonlinear optics. The underlying common aspect of all these topics, and hence the main focus and perspective from which they are explained here, is the attempt to develop analogue models for gravitational systems. The original and main motivation of the field is the verification and study of Hawking radiation from a horizon: the enabling feature (...) is the possibility to generate horizons in the laboratory with a wide range of physical systems that involve a flow of one kind or another. The years around 2010 and onwards witnessed a sudden surge of experimental activity in this expanding field of research. However, building an expertise in analogue gravity requires the researcher to be equipped with a rather broad range of knowledge and interests. The aim of this book is to bring the reader up to date with the latest developments and provide the basic background required in order to appreciate the goals, difficulties and success stories in the field of analogue gravity. Each chapter of the book treats a different topic explained in detail by the major experts for each specific discipline. The first chapters give an overview of black hole spacetimes and Hawking radiation before moving on to describe the large variety of analogue spacetimes that have been proposed and are currently under investigation. This introductory part is then followed by an in-depth description of what are currently the three most promising analogue spacetime settings, namely surface waves in flowing fluids, acoustic oscillations in Bose-Einstein condensates and electromagnetic waves in nonlinear optics. Both theory and experimental endeavours are explained in detail. The final chapters refer to other aspects of analogue gravity beyond the study of Hawking radiation, such as Lorentz invariance violations and Brownian motion in curved spacetimes, before concluding with a return to the origins of the field and a description of the available observational evidence for horizons in astrophysical black holes.

Edmund Husserl, founder of the phenomenological movement, is usually read as an idealist in his metaphysics and an instrumentalist in his philosophy of science. In _Nature’s Suit_, Lee Hardy argues that both views represent a serious misreading of Husserl’s texts. Drawing upon the full range of Husserl’s major published works together with material from Husserl’s unpublished manuscripts, Hardy develops a consistent interpretation of Husserl’s conception of logic as a theory of science, his phenomenological account of truth and (...) rationality, his ontology of the physical thing and mathematical objectivity, his account of the process of idealization in the physical sciences, and his approach to the phenomenological clarification and critique of scientific knowledge. Offering a jargon-free explanation of the basic principles of Husserl’s phenomenology, _Nature’s Suit_ provides an excellent introduction to the philosophy of Edmund Husserl as well as a focused examination of his potential contributions to the philosophy of science. While the majority of research on Husserl’s philosophy of the sciences focuses on the critique of science in his late work, _The Crisis of European Sciences_, Lee Hardy covers the entire breadth of Husserl’s reflections on science in a systematic fashion, contextualizing Husserl’s phenomenological critique to demonstrate that it is entirely compatible with the theoretical dimensions of contemporary science.

Inasmuch as physical theories are formalizable, set theory provides a framework for theoretical physics. Four speculations about the relevance of set theoretical modeling for physics are presented: the role of transcendental set theory (i) in chaos theory, (ii) for paradoxical decompositions of solid three-dimensional objects, (iii) in the theory of effective computability (Church-Turing thesis) related to the possible “solution of supertasks,” and (iv) for weak solutions. Several approaches to set theory and their advantages (...) and disadvatages for physical applications are discussed: Canlorian “naive” (i.e., nonaxiomatic) set theory, contructivism, and operationalism. In the author's opinion, an attitude of “suspended attention” (a term borrowed from psychoanalysis) seems most promising for progress. Physical and set theoretical entities must be operationalized wherever possible. At the same time, physicists should be open to “bizarre” or “mindboggling” new formalisms, which need not be operationalizable or testable at the lime of their creation, but which may successfully lead to novel fields of phenomenology and technology.

Bachelard regarded the scientific changes that took place in the early twentieth century as the beginning of a new era, not only for science, but also for philosophy. For him, the theory of relativity and quantum mechanics had shown that a new philosophical ontology and a new epistemology were required. I show that the type of philosophy with which he was more closely associated, in particular that of Léon Brunschvicg, offered to him a crucial starting point. Brunschvicg never considered (...) scientific objects as independent of the mind, and as a consequence questions such as the existence of particles independently of the mind, theory or apparatus, were absent from his philosophy, which was rather aimed at analyzing the mind critically, and above all historically. Bachelard accepted the fundamental ideas of Brunschvicg’s philosophy; however, his own reading of contemporary science enabled him to go beyond it, as shown by his emphasis on the social production of knowledge, and by his removal of the distinction between ideas and technologically produced objects of knowledge. For him, modern science teaches philosophy that knowledge is not a phenomenology but rather a ‘phenomenotechnique’. I argue that Bachelard’s view that philosophy ‘should follow science’ stems from moral considerations.Keywords: Gaston Bachelard; Léon Brunschvicg; Phenomenotechnique; Chosisme; Theory of relativity; Quantum mechanics.

It has been claimed that Massimi’s recent perspectival approach to science sits in tension with a realist stance. I shall argue that this tension can be defused in the quantum context by recasting Massimi’s perspectivalism within a phenomenological framework. I shall begin by indicating how the different but complementary forms of the former are manifested in the distinction between certain so-called ‘-epistemic’ and ‘-ontic’ understandings of quantum mechanics, namely QBism and Relational Quantum Mechanics, respectively. A brief consideration of Dieks’ (...) perspectivism will then lead to a consideration of the much-maligned and typically dismissed role of the observer in the measurement process. This opens the door to London and Bauer’s presentation of a form of ‘phenomenological quantum perspectivalism’ that brings together Massimi’s two forms and explicitly eschews the ‘naïve’ realism that creates the above tension. I shall conclude with some reflections on how intersubjectivity can still be established within this framework, focusing in particular on how Massimi’s idea of ‘interlacing’ scientific perspectives can be accommodated, using the example of a ‘new cosmopolitanism’ that gave rise to Bose-Einstein statistics.

This volume brings together philosophers and physicists to explore the parallels between Quantum Bayesianism, or QBism, and the phenomenological tradition. It is the first book exclusively devoted to phenomenology and quantum mechanics. By emphasizing the role of the subject's experiences and expectations, and by explicitly rejecting the idea that the notion of physical reality could ever be reduced to a purely third-personal perspective, QBism exhibits several interesting parallels with phenomenology. The central message of QBism is that quantum probabilities must (...) be interpreted as the experiencing agent's personal Bayesian degrees of belief--degrees of belief for the consequences of their actions on a quantum system. The chapters in this volume elaborate whether and specify how phenomenology could serve as the philosophical foundation of QBism. This objective is pursued from the perspective of QBists engaging with phenomenology as well as the perspective of phenomenologists engaging with QBism. These approaches enable us to realize a better understanding of quantum mechanics and the world we live in, achieve a better understanding of QBsim, and introduce the phenomenological foundations of quantum mechanics. Phenomenology and QBism is an essential resource for researchers and graduate students working in philosophy of physics, philosophy of science, quantum mechanics, and phenomenology. (shrink)

Science is a process, through which theoretical frameworks are developed, new phenomena defined and discovered, and properties of entities tested. The goal of this dissertation is to illustrate how high-energy physics exemplified the process of theory construction from the 1950s to 1970s, and the promising ways in which it can continue to do so today. The lessons learned from the case studies examined here can inform future physics, and may provide methodological clues as to the best way (...) forward today. I examine the discovery of parity nonconservation in weak interactions, the emergence of Yang-Mills theories as the foundation of the standard model, and contemporary precision testing of quantum electrodynamics. In each of these cases, I examine the details of the physicists’ practice to draw conclusions regarding the epistemology behind successful episodes of theory construction. I reconstruct the methodology of each episode in order to find generalizable lessons to apply to contemporary issues at the frontiers of the search for a theory of quantum gravity. In order to understand the many moving parts in each case study, I introduce a new terminology to distinguish the “parts” of a scientific discipline, inspired by the literature on scientific modelling. These terms—theoretical framework, dynamical model, phenomenological model, experiment, and mathematical tools—are meant to aid in investigating other quantitative scientific disciplines beyond high-energy physics. Ultimately, high-energy physics is at its best when various avenues of theoretical ideas are being pursued, spurring the development of new mathematical techniques to use as tools, and new ideas are quickly and vigorously tested experimentally. Proliferation of new ideas in response to theoretical developments is characteristic of the era of construction of the standard model, and is still ongoing in precision testing of quantum electrodynamics today.

Currently, string theory represents the only advanced approach to a unification of all interactions, including gravity. In spite of the more than thirty years of its existence, the sequence of metamorphosis it ran through, and the ever more increasing number of involved physicists, until now, it did not make any empirically testable predictions. Because there are no empirical data incompatible with the quantum field theoretical standard model of elementary particle physics and with general relativity, the only motivations for (...) string theory rest in the mutual incompatibility of the standard model and of general relativity as well as in the metaphysics of the unification program of physics, aimed at a final unified theory of all interactions including gravity. But actually, it is completely unknown which physically interpretable principles could form the basis of string theory. At the moment, "string theory" is no theory at all, but rather a labyrinthic structure of mathematical procedures and intuitions which get their justification from the fact that they, at least formally, reproduce general relativity and the standard model of elementary particle physics as low energy approximations. However, there are now strong indications that string theory does not only reproduce the dynamics and symmetries of our standard model, but a plethora of different scenarios with different low energy nomologies and symmetries. String theory seems to describe not only our world, but an immense landscape of possible worlds. So far, all attempts to find a selection principle which could be motivated intratheoretically remained without success. So, recently the idea that the low energy nomology of our world, and therefore also the observable phenomenology, could be the result of an anthropic selection from a vast arena of nomologically different scenarios entered string theory. Although multiverse scenarios and anthropic selection are not only motivated by string theory, but lead also to a possible explanation for the fine tuning of the universe, they are concepts which transcend the framework defined by the epistemological and methodological rules which conventionally form the basis of physics as an empirical science.

In this paper, I address the issue of to what extent the theory-dominated view of scientific experimentation describes scientific practice. I rely on a time period from the history of High Energy Physics (HEP), which spans from early 1960s to early 1970s. I argue that theory-ladenness of experimentation (TLE), which grounds theory-dominated conception of experimentation is too coarse-grained inasmuch as it prevents us from seeing the correct relationship that exists between theorizing and experimenting in the scientific (...) practice of HEP. I articulate that in order to be able to get a better understanding of scientific practice, a revision needs to be made in the general conception of TLE. I propose that such a revision is possible if we abandon the commitment that experimentation is always driven by theory. I consider what I call “theory-drivenness” of experimentation (TDE) as a form of theory-ladenness, which amounts to the claim that experiments, from their initial design up to their final stage, are carried out under the framework of a prevailing theory for the purpose of providing definite answers to specific questions already posed by the same theory. I argue that electron-proton inelastic scattering experiments in HEP were firstly carried out without having any recourse to a phenomenological model. From here, I claim that these experiments are not theory-laden in the sense implied by TDE. On the other hand, I argue, inelastic scattering experiments are theory-laden due to the fact that the scientists who perform them are committed to background theories of HEP. That is, I admit the validity of TLE as a philosophical claim, but I attribute a weaker status to it as opposed to its general conception. That is, I propose to differentiate TDE from TLE by claiming that TLE does not entail TDE. (shrink)

This book introduces the phenomenology and theory of hadron form factors in a consistent manner, deriving step-by-step the key equations, defining the form factors from the matrix elements of hadronic transitions and deriving their symmetry relations. Explained are several general concepts of particle theory and phenomenology exemplified by hadron form factors. The main emphasis here is on learning the analytical methods in particle phenomenology. Many examples of hadronic processes involving form factors are considered, from the pion electromagnetic scattering (...) to heavy B-meson decays. In the second part of the book modern techniques of the form factor calculation, based on the method of sum rules in the theory of strong interactions, quantum chromodynamics, are introduced in an accessible manner. This book will be a useful guide for graduate students and early-career researchers working in the field of particle phenomenology and experiments. Features: The first book to address the phenomenology of hadron form factors at a pedagogical level in one coherent volume. Contains up-to-date descriptions of the most important form factors of the electroweak transitions investigated in particle physics experiments. (shrink)

Gernot Böhme’s original proposal regarding an aesthetic as a philosophic theory of perceptual knowledge could, in our opinion, be usefully compared with certain aspects, historical-theoretical and methodological, of Gestalt psychology. From an historical point of view there is the attention commonly paid to the work of the 18th-century philosopher, Alexander Gottlieb Baumgarten, considered as an important precursor of the study of sensitive knowledge, while the subsequent basic themes of the perceptual-cognitive approach, of the expressive qualities, of the distinction “physical (...) reality /actual reality,” of the physiognomic problem, to cite but a few, recall nuclear questions, although perhaps not traditionally included in the “major canon”—to use a terminological proposal of Rocco Ronchi’s—of philosophy and specifically of experimental phenomenology.

Lambert Wiesing's The Philosophy of Perception challenges current theories of perception. Instead of attempting to understand how a subject perceives the world, Wiesing starts by taking perception to be real. He then asks what this reality means for a subject. In his original approach, the question of how human perception is possible is displaced by questions about what perception obliges us to be and do. He argues that perception requires us to be embodied, to be visible, and to continually participate (...) in the public and physical world we perceive. Only in looking at images, he proposes, can we achieve something like a break in participation, a temporary respite from this, one of perception's relentless demands. Wiesing's methods chart a markedly new path in contemporary perception theory. In addition to identifying common ground among diverse philosophical positions, he identifies how his own, phenomenological approach differs from those of many other philosophers, past and present. As part of the argument, he provides a succinct but comprehensive survey of the philosophy of images His original critical exposition presents scholars of phenomenology, perception and aesthetics with a new, important understanding of the old phenomenon, the human being in the world.

ArgumentIn the theory-dominated view of scientific experimentation, all relations of theory and experiment are taken on a par; namely, that experiments are performed solely to ascertain the conclusions of scientific theories. As a result, different aspects of experimentation and of the relations of theory to experiment remain undifferentiated. This in turn fosters a notion of theory-ladenness of experimentation (TLE) that is toocoarse-grainedto accurately describe the relations of theory and experiment in scientific practice. By contrast, in (...) this article, I suggest that TLE should be understood as anumbrella conceptthat has different senses. To this end, I introduce a three-fold distinction among the theories of high-energy particle physics (HEP) as background theories, model theories, and phenomenological models. Drawing on this categorization, I contrast two types of experimentation, namely, “theory-driven” and “exploratory” experiments, and I distinguish between the “weak” and “strong” senses of TLE in the context of scattering experiments from the history of HEP. This distinction enables identifying the exploratory character of the deep-inelastic electron-proton scattering experiments – performed at the Stanford Linear Accelerator Center (SLAC) between the years 1967 and 1973 – thereby shedding light on a crucial phase of the history of HEP, namely, the discovery of “scaling,” which was the decisive step towards the construction of quantum chromo-dynamics as a gauge theory of strong interactions.

Since Jackendoff has shown that language facilitates abstract and complex thought by making possible subtle manipulations of the focus of attention, and since the kind of attention relevant here is attention to aspects of intentional objects in conscious awareness, it follows that the abstract and complex thinking that language facilitates owes much to the working of a conscious process. This, however, conflicts with Jackendoff's view of consciousness as something which does not play a direct part in thinking, but is only (...) a byproduct of a non-conscious computational process in the brain which does the real thinking. I argue that, since Jackendoff s phenomenology of language shows that attention plays such an important part in thinking, yet language can help us attend only to what we are conscious of consciousness does play an important part in thinking. Moreover, consciousness cannot be merely an epiphenomenal byproduct separable in principle from underlying physical mechanisms, because this would imply that consciousness itself is not physical, which would lead to dualism. But if consciousness is inseparable from its physiological substratum, then it also causes whatever effects the physiological substratum causes. (shrink)

Brentano and his students were the first to wrestle an Aristotelian perceptual concept, intentionality, into the modern metaphysics of mind. This dissertation recovers theories of Franz Brentano , Kazimierz Twardowski , and Edmund Husserl by appreciating each as an unique attempt to make a modern home for the ancient doctrine of "aboutness." The dissertation corrects a broad range of contemporary misunderstandings and criticisms of Brentano School philosophy, in particular one advanced by Martin Heidegger . ;Brentano's Psychology from an Empirical Standpoint (...) is marked by deep tensions between the doctrine of intentional inexistence and its Comtean positivism; Brentano treated mental contents as Comtean phenomena. Understanding physical phenomena as facts presented by sensations, and as syntactic building-blocks for higher-order mental phenomena, I reject misinterpretations of Brentano as either anti-reductionist or Immanentist. The unstable Brentanian account of intentionality was inherited by his student Twardowski. On the Content and Object of Presentations hoped to shore up Brentano's position with a crisp distinction of mental contents from worldly objects; Twardowski was among the first to attempt to integrate intentionality with a modern representationalism. The result was subjective mental content through which objects in the extra-conscious world are represented, a watershed in the history of representationalisms. Twardowski treated the representational relation as resemblance and mental contents as " quasi pictures," but Twardowski was among the first distinctly 20th Century representationalists, those who treat mental content as extra-conscious. Husserl's solution to Brentano's problem rejected the positivistic phenomena of his teacher and criticized the quasi-pictures of his classmate. The heart of the Logical Investigations account of consciousness is a distinction between two kinds of mental content. The intentional objects of the world at large are our mental contents , the very things that remain fixed while our mental contents fluctuate. Understanding this dynamic relation between two kinds of mental content, I reject readings of the Investigations which treat ideal content as either Fregean or Aristotelian. The recovery of Husserl's notion of ideality, one strategy amongst several in attempts to integrate intentionality with modern metaphysics, abets a defense of early Husserlian phenomenology from one of its most powerful critics.

Modern economics, with its use of advanced mathematical methods, is often looked upon as the physics of the social sciences. It is here argued that deductive analyses are more important in economics than in physics, because the economists more seldom can confirm phenomenological laws directly. The economist has to use assumptions from fundamental theory when trying to bridge the gap between observations and phenomenological laws. Partly as a result of the difficulties of establishing phenomenological (...) laws, analyses of idealized 'model-economies' play a more important, but mainly heuristic role, in economics. (shrink)

The current technoscientific progress has led to a sectorization in the philosophy of science. Today the philosophy of science isn't is informal interested in studying old problems about the general characteristics of scientific practice. The interest of the philosopher of science is the study of concepts, problems and riddles of particular disciplines. Then, within this progress of philosophy of science, neuroscientific research stands out, because it invades issues traditionally addressed by the humanities, such as the nature of consciousness, action, knowledge, (...) normativity, etc. As a result, the new area of interdisciplinary study of neuroscience and philosophy arises: neurophilosophy. This emerging area applies neuroscientific concepts to traditional philosophical questions, limiting their responses to neuroscientific revelations about nervous systems. Neurophilosophy research focuses on problems related to the indirect nature of mind and brain, computational or representative analysis of brain process, relationships between psychological and neuroscientific research, adequate adaptations of physical and philosophical concepts in neuroscience and the place of cognitive functions. Now, the temporal representation of conscious experience and the types of the neural architecture to represent objects in time have aroused scientific interest. Under these interests, we focus on the studies on the temporary triadic structure of phenomenological consciousness in Dan Lloyd and Rick Grush. From Grush’s studies, the importance of Kantian ideas for cognitive neuroscience emerges, due to the active way in which Kant conceived space and time as forms of intuition, within which the mind interprets its experience. Under this perspective, the theoretical arguments of Dennett-Kinsbourne and Eagleman-Sejnowski represent winks in the direction of Kant-Husserl within the neuroscientific goal while considering that the contents provided by the mind included space, objects and perception of causal relationships. Then, theories of cognitive neuroscience are beginning to suggest that these elements are also, as Kant argued, interpretative elaborations provided by mind / brain, and not only content received from outside. In other words, current cognitive neuroscientific theories try to pass from its Humean phase to a Kantian phase. So, the challenge has been to explain that these elements are provided by the mind and the world itself, and how they have the content they have come from. These are lacking in current studies. Filling this gap helps to involve the analysis of the scientist’s experience in his theoretical attitude. In this sense, an investigation under the Kantian-Husserlian approach that involves pure intuitions a priori with the experience of the scientific and neuroscientific concepts represents a ground-breaking. At present, a neurophilosophical study about this does not exist. In this sense, one feasible proposal for research would be based on the application of neuroscientific results of Moser-Britt to philosophical problems of foundational notions in relativistic physics: space, time, space-time, field, etc., under the Kantian-Husserlian approach, which allows to demonstrate the multidisciplinary link between neurophilosophy and physics. This represents a ground-breaking area in current interests in scientific research, with a positive impact in the field of neuroscience, and contributing to the study of abstraction emphasizing the importance of Kant’s Copernican turn and Husserl’s phenomenological ideas in the construction of physical theories. -/- .

In the author’s previous contribution to this journal (Rosen 2015), a phenomenological string theory was proposed based on qualitative topology and hypercomplex numbers. The current paper takes this further by delving into the ancient Chinese origin of phenomenological string theory. First, we discover a connection between the Klein bottle, which is crucial to the theory, and the Ho-t’u, a Chinese number archetype central to Taoist cosmology. The two structures are seen to mirror each other in (...) expressing the psychophysical (phenomenological) action pattern at the heart of microphysics. But tackling the question of quantum gravity requires that a whole family of topological dimensions be brought into play. What we find in engaging with these structures is a closely related family of Taoist forebears that, in concert with their successors, provide a blueprint for cosmic evolution. Whereas conventional string theory accounts for the generation of nature’s fundamental forces via a notion of symmetry breaking that is essentially static and thus unable to explain cosmogony successfully, phenomenological/Taoist string theory entails the dialectical interplay of symmetry and asymmetry inherent in the principle of synsymmetry. This dynamic concept of cosmic change is elaborated on in the three concluding sections of the paper. Here, a detailed analysis of cosmogony is offered, first in terms of the theory of dimensional development and its Taoist (yin-yang) counterpart, then in terms of the evolution of the elemental force particles through cycles of expansion and contraction in a spiraling universe. The paper closes by considering the role of the analyst per se in the further evolution of the cosmos. (shrink)

Starting with the claim that Quantum Mechanics is in need of a new interpretation that would allow us to understand the phenomena of this realm, I wish to analyse in this paper de Ronde's theory of power and potentia from a phenomenological perspective. De Ronde's claim is that the reason for the lack of success in the foundations of QM is due to the reluctance of both physicists and philosophers to explore the possibility of finding a new ontology, (...) new concepts for the physical theory. De Ronde proposes such new ontology and the question I wish to address here, is whether his ontology is conceptually plausible. I will, for this purpose, recur to Edmund Husserl's phenomenology. After presenting some of the basic concepts and methodological tools of this theory, I shall apply them to de Ronde's ontology to determine the viability of his theory. (shrink)

In the theory-dominated view of scientific experimentation, all relations of theory and experiment are taken on a par; namely, that experiments are performed solely to ascertain the conclusions of scientific theories. As a result, different aspects of experimentation and of the relation of theory to experiment remain undifferentiated. This in turn fosters a notion of theory-ladenness of experimentation that is too coarse-grained to accurately describe the relations of theory and experiment in scientific practice. By contrast, (...) in this article, I suggest that TLE should be understood as an umbrella concept that has different senses. To this end, I introduce a three-fold distinction among the theories of high-energy particle physics as background theories, model theories and phenomenological models. Drawing on this categorization, I contrast two types of experimentation, namely, “theory-driven” and “exploratory” experiments, and I distinguish between the “weak” and “strong” senses of TLE in the context of scattering experiments from the history of HEP. This distinction enables to identify the exploratory character of the deep-inelastic electron-proton scattering experiments—performed at the Stanford Linear Accelerator Center between the years 1967 and 1973—thereby shedding light on a crucial phase of the history of HEP, namely, the discovery of “scaling”, which was the decisive step towards the construction of quantum chromo-dynamics as a gauge theory of strong interactions.

These articles and speeches by the Nobel Prize-winning physicist date from 1934 to 1958. Rather than expositions on quantum physics, the papers are philosophical in nature, exploring the relevance of atomic physics to many areas of human endeavor.

Theories that combine physicalism with phenomenal concepts abandon the phenomenal irrealism characteristic of 1950s physicalism, thereby leaving physicalists trying to reconcile themselves to concepts appropriate only to dualism. Physicalists should instead abandon phenomenal concepts and try to develop our concepts of conscious states. Employing an account of concepts as structured mental representations, and motivating a model of conceptual development with semantic externalist considerations, I suggest that phenomenal concepts misrepresent their referents, such that if our conception of consciousness incorporates them, it (...) needs development. I then argue that the ?phenomenal concept strategy? (PCS) of a purely cognitive account of the distinction between phenomenal and physical concepts combines physicalism with phenomenal concepts only by misrepresenting physical properties. This is because phenomenal concepts carry ontological commitment, and I present an argument to show the tension between this commitment and granting ontological authority to physical concepts only. In the final section, I show why phenomenal concepts are more ontologically committed than PCS theorists can allow, revive U.T. Place's notion of a ?phenomenological fallacy? to explain their enduring appeal, and then suggest some advantages of functional analyses of concepts of conscious states over the phenomenal alternative.

Phenomenology is the study of appearance as such. It is a branch of both Ontology and Epistemology, since appearing is being known. By an ‘appearance’ is meant any existent which impinges on consciousness, anything cognized, irrespective of any judgment as to whether it be ‘real’ or ‘illusory.’ The evaluation of a particular appearance as a reality or an illusion is a complex process, involving inductive and deductive logical principles and activities. Opinion has to earn the status of strict knowledge. Knowledge (...) develops from appearances, which may be: (a) objects of perception, i.e. concrete phenomena in the physical or mental domains; (b) objects of intuition, i.e. one’s subjective self, cognitions, volitions and valuations (non-phenomenal concretes); and/or (c) objects of conception, i.e. simple or complex abstracts of preceding appearances. Abstraction relies on apprehensions of sameness and difference between appearances (including received or projected appearances, and projected negations of appearances). Coherence in knowledge (perceptual, intuitive and conceptual) is maintained by apprehensions of compatibility or incompatibility. Words facilitate our construction of conceptual knowledge, thanks to their intentionality. The abstract concepts most words intend are common characters or behaviors of particulars (concrete material, mental or subjective experiences). Granting everything in the world is reducible to waves, ‘universals’ would be equalities or proportionalities in the measures of the features, motions and interrelations of particular waves. Such a theory of universals would elucidate sensation and memory. In attempting to retrace the development of conceptual knowledge from experience, we may refer to certain major organizing principles. It is also important to keep track of the order of things in such development, interrelating specific concepts and specific experiences. By proposing a precise sequence of events, we avoid certain logical fallacies and are challenged to try and answer certain crucial questions in more detail. Many more topics are discussed in the present collection of essays, including selfhood, adduction and other logical issues, the status of mathematical concepts and theology. (shrink)

Since Jackendoff has shown that language facilitates abstract and complex thought by making possible subtle manipulations of the focus of attention, and since the kind of attention relevant here is attention to aspects of intentional objects in conscious awareness, it follows that the abstract and complex thinking that language facilitates owes much to the working of a conscious process. This, however, conflicts with Jackendoff's view of consciousness as something which does not play a direct part in thinking, but is only (...) a byproduct of a non-conscious computational process in the brain which does the real thinking. I argue that, since Jackendoff s phenomenology of language shows that attention plays such an important part in thinking, yet language can help us attend only to what we are conscious of consciousness does play an important part in thinking. Moreover, consciousness cannot be merely an epiphenomenal byproduct separable in principle from underlying physical mechanisms, because this would imply that consciousness itself is not physical, which would lead to dualism. But if consciousness is inseparable from its physiological substratum, then it also causes whatever effects the physiological substratum causes. (shrink)

In this paper I explicate what it means to see phenomenologically for an able-bodied researcher in the field of disability, and how this seeing yields a non-reductionistic understanding of the phenomenon of disability. My aim is to show how in this context, I, as a human and social scientist can use phenomenological methodology for both collecting and interpreting data. Though phenomenological philosophy can provide the basis of social scientific epistemology, it does not lend itself easily to a single (...) specific or programmatic social scientific methodology. I offer possible ways of using phenomenological theory, methodology and techniques in order to understand the experience of a person with physical disability learning to use a wheelchair. I use data from a clinical encounter between a physical therapist (PT) and an adult with Spinal Cord Injury (SCI) in an inpatient rehabilitation hospital in Midwestern United States in order to flesh out phenomenological seeing. I conclude with implications for qualitative researchers who use phenomenological methods to inform their work. (shrink)

Through an exploration of theoretical physics, this paper suggests the need for regrounding natural science in phenomenological philosophy. To begin, the philosophical roots of the prevailing scientific paradigm are traced to the thinking of Plato, Descartes, and Newton. The crisis in modern science is then investigated, tracking developments in physics, science's premier discipline. Einsteinian special relativity is interpreted as a response to the threat of discontinuity implied by the Michelson-Morley experiment, a challenge to classical objectivism that Einstein (...) sought to counteract. We see that Einstein's efforts to banish discontinuity ultimately fall into the “black hole” predicted in his general theory of relativity. The unavoidable discontinuity that haunts Einstein's theory is also central to quantum mechanics. Here too the attempt has been made to manage discontinuity, only to have this strategy thwarted in the end by the intractable problem of quantum gravity. The irrepressible discontinuity manifested in the phenomena of modern physics proves to be linked to a merging of subject and object that flies in the face of Cartesian philosophy. To accommodate these radically non-classical phenomena, a new philosophical foundation is called for: phenomenology. Phenomenological philosophy is elaborated through Merleau-Ponty's concept of depth and is then brought into focus for use in theoretical physics via qualitative work with topology and hypercomplex numbers. In the final part of this paper, a detailed summary is offered of the specific application of topological phenomenology to quantum gravity that was systematically articulated in The Self-Evolving Cosmos (Rosen 2008a).

The phenomenological theory of constitution promises a solution for the problem of consciousness insofar as it changes the traditional terms of this problem by systematically correlating subject and object in the unifying context of intentional acts. I argue that embodied constitution must depend upon the role of kinesthesia as a constitutive operator. In pursuing the path of intentionality in its descent from an idealistic level of pure constitution to this fully embodied kinesthetic constitution, we are able to gain (...) access to different ontological regions such as physical thing, owned body and shared world. Neuroscience brings to light the somatological correlates of noemata. Bridging the gap between incarnation and naturalisation represents the best way of realizing the foundational program of transcendental phenomenology. (shrink)

This article argues that phenomenological treatment of physical problems is more powerful than fundamental treatment. Developments in the field of superconductivity present us with a clear example of such superiority. The BCS (Bardeen, Cooper and Schrieffer) was accepted as the fundamental theory of superconductivity for a long time. Nevertheless, Landau and Ginzburg phenomenological model has so far proven to be a more fruitful theoretical representation to understand and to predict the features of superconductivity and superconductive materials.

The basic operational devices in a particle theory are detectors which show that a particle is “here, now” rather than “there, then.” Successful operation of these devices requires a limiting velocity. Given auxiliary devices which can change particle velocities in both magnitude and direction, the Lorentz-invariant mass can be defined. The wave-particle duality operationally required to explain the scattering of particles from a diffraction grating then predicts fluctuations in particle number (the Wick-Yukawa mechanism), if we postulate a smallest mass. (...) We show that this suffices to establish the conventional quantum mechanical scattering formalism without postulating either “interactions” or “analyticity.” By introducing the phase change due to external electromagnetic fields, we can describe the auxiliary devices assumed above to an accuracy ofe 2/hc, thus completing the operational definition to that accuracy.

This very ambitious and remarkably detailed book examines some of the most fundamental themes in Husserl's philosophy. As is evident from the title, the book has two parts, the first of which (pp. 1-101) discusses Husserl's methodology, esp. the phenomenological reduction, and the second of which (pp. 103-347) investigates the themes of space, time, and other. These themes are selected because they are central to our mundane and embodied experience of an objective, physical and animate world.

: Daniel Dennett's philosophical abolition of mind is examined with reference to its methodology, intent, philosophic origins, and internal consistency. His treatment of the contents of perception and introspection is shown to be derivative from realist reductionist misinterpretations of physics, physiology, and phenomenology of perception. In order to rectify inconsistencies of that realistic paradigm devolved from psycho-neural identity theory of mid-twentieth century, Dennett radicalizes its logic and redefines even veridical phenomenology of exteroception to be "illusory." This measure in (...) extremis still does not save the appearances of his predecessors, nevertheless, for Dennett tacitly presupposes the existence of veridical phenomenology in his very treatment of non-veridical sensory phenomena that he uses to argue analogically from, to thereby suggest the plausibility of a parallel illusoriness of veridical phenomena of perception and introspection. This inhering inconsistency renders unsound Dennett's radical extension of the logic of identity theory, and ironically shows up the persistence of mental phenomenology that extant reductionism appears so desirous to argumentively eliminate. Nonetheless there is much to be learned from such an analysis of Dennett's purported elimination of mental contents, for a generalization of our critique throws light on the occult assumptions underlying realism and reductionism since early identity theory and its variants, and upon the possible viability of that programme as a whole., Someone does a sum in his head. He uses the result, let's say, for building a bridge or a machine[horizontal ellipsis]. There surely must have been calculation going on, and there was. For he knows that, and how, he calculated; and the correct result he got would be inexplicable without calculation.-But what if I said: "It strikes him as if he had calculated[horizontal ellipsis]." (Wittgenstein, Philosophical Investigations, [S] 364), My debt to Wittgenstein is large and longstanding. When I was an undergraduate, he was my hero[horizontal ellipsis].

The experience of being in love involves a longing for union with the other, where an important part of this longing is sexual desire. But what is the relation between being in love and sexual desire? To answer this it must first be seen that the expression ‘in love’ normally refers to a personal relationship. This is because to be ‘in love’ is to want to be loved back. This much would be predicted by equity and social exchange theories of (...) interpersonal attraction. Findings suggest however that love differs fundamentally from liking and, consequently, distinct approaches to the theory of love have been developed. A phenomenological theory is then put forward which suggests that the experience of being in love involves a complex of desires for reciprocal vulnerability in order to care and be cared for. Sexual desire is then seen to involve the physical expression of these desires in the form of desires for mutual baring in order to caress and be caressed. Unlike love, however, sexual desire need not refer to the other person's desires. This is supported by the existence of sexual desires like fetishism. It is concluded that other desires which often appear in instances of being in love are not basic to the experience of being in love. (shrink)
