Over the last few decades, our theories of fundamental physics have become increasingly detached from empirical data. Recently, Richard Dawid has argued that the progressive separation of theory from experiment is concomitant with a number of changes in the methodology of the discipline. More precisely, Dawid has argued that the new methods of fundamental physics amount to a form of non-empirical confirmation, and that physical theories may therefore be confirmed even in the absence of empirical (...) data. In this paper, I critically engage with Dawid's views on non-empirical physics. My main target is the excessively central role that, in my view, the notion of non-empirical confirmation plays on Dawid's analysis. I will therefore argue that, while non-empirical methods may legitimately be employed in physics, those are not always deployed with the purpose of confirming scientific theories. Non-empirical arguments may also be used in order to ground pragmatic choices regarding what theories deserve to be further developed—and this is an aspect of the work that non-empirical methods perform that cannot be solely understood in terms of Dawid's notion of non-empirical confirmation. I support these claims by making use of a case-study from the early history of particle physics. The case-study concerns a theory of the strong force that J. J. Sakurai introduced in 1960. As we shall see, both the genesis of Sakurai's theory as well as the arguments that he used to defend it provide direct support for my own views on the role that non-empirical methods play in physics. Finally, I conclude the paper by introducing a notion that I believe is useful in making sense of the manner in which the pragmatic and the epistemic dimensions of non-empirical reasoning relate to each other, namely the notion of a cognitive attitude. -/- .

The author considers the empirical component of physical theories. He studies the origin and development of the theory of physical experiment, the structure and gnoseological hypotheses of the measuring process, as well as the relativity principle concerning the measuring equipment. Examples of modern physical theories are used in order to demonstrate the influence of experimental facts on the formation and development, verification and accepting of these theories in the structure of scientific systems. The role of accidental experimental facts in (...) this process is also the subject. (shrink)

This book presents the first detailed account of Werner Heisenberg’s failed attempt to find a theory of everything in the autumn of his career. It further investigates what we can learn from his failure in relation to the search for a final theory of physics, an endeavour that continues to define research in fundamental physics to this day. Thereby it provides the first historically informed contribution to the current debate on post-empirical physics and the state of (...) particle physics. (shrink)

In this paper, I reconstruct an argument of Aristidis Arageorgis against empirical underdetermination of the state of a physical system in a C*-algebraic setting and explore its soundness. The argument, aiming against algebraic imperialism, the operationalist attitude which characterized the first steps of Algebraic Quantum Field Theory, is based on two topological properties of the state space: being T1 and being first countable in the weak*-topology. The first property is possessed trivially by the state space while the latter is (...) highly non-trivial, and it can be derived from the assumption of the algebra of observables’ separability. I present some cases of classical and of quantum systems which satisfy the separability condition, and others which do not, and relate these facts to the dimension of the algebra and to whether it is a von Neumann algebra. Namely, I show that while in the case of finite-dimensional algebras of observables the argument is conclusive, in the case of infinite-dimensional von Neumann algebras it is not. In addition, there are cases of infinite-dimensional quasilocal algebras in which the argument is conclusive. Finally, I discuss Porrmann's construction of a net of local separable algebras in Minkowski spacetime which satisfies the basic postulates of Algebraic Quantum Field Theory. (shrink)

This paper defends wave function realism against the charge that the view is empirically incoherent because our evidence for quantum theory involves facts about objects in three-dimensional space or space-time . It also criticizes previous attempts to defend wave function realism against this charge by claiming that the wave function is capable of grounding local beables as elements of a derivative ontology.

Symmetries in physics are most commonly recognized and discussed in terms of their function in the mathematical formalism of the theories. Discussion of the observation of symmetries in nature is less common. This paper analyses the observation of particular symmetries such as Lorentz and gauge symmetries, distinguishing between direct observation of the symmetry itself and indirect evidence, the latter being the observation of some consequence of the symmetry are, in an important sense, directly observed, while local symmetries such as (...) gauge symmetry are not.

I shall argue in this article that there are certain objectual and methodological boundaries imposed by the nature of physics that all formulations of physicalism based on physical theories should respect. Therefore, empirical physicalism – i.e., the sort of physicalism that is eager to accept all the entities included in some future, ideal and complete physical theory and all entities dependent on them (see Jeffrey Poland and Janice Dowell) – is already committed to the exclusion of certain sorts (...) of entities from its ontological inventory and it is far less tolerant than one might expect. After having presented my argument, I shall describe four plausible boundaries to what can be studied by physics. The boundaries will contribute to constructing a new version of physicalism, i.e., physics physicalism, whose acceptance is entailed by the acceptance of empirical physicalism. Finally, I shall briefly deal with three objections against my strategy and I shall evaluate the consequences of the acceptance of my conclusions for both physicalists and non-physicalists. (shrink)

2. The Contingency and A posteriority Constraint: A formulation of the thesis must make physicalism come out contingent and a posteriori. First, physicalism is a contingent truth, if it is a truth. This means that physicalism could have been false, i.e. there are counterfactual worlds in which physicalism is false, for example, counterfactual worlds in which there are miracle -performing angels.[9] Moreover, if physicalism is true, our knowledge of its truth is a posteriori. This is to say that there are (...) ways the world could turn out to be such that physicalism is false. For example, if there are miracle -performing angels, then physicalism is false. So there are worlds considered as actual in which physicalism is false.[10] For short, call this ‘the a posteriority constraint’.[11]. (shrink)

Physical activity and sports are extremely essential elements for physical and mental health among adolescents. Around 30% of 16 years old and above in Malaysia have mental health issues. For this purpose, 512 university students from Malaysia were surveyed through social media, with 74% response rate. Structural equation model partial least square was used to examine the effect of PA and sports on mental health. The results revealed that both PA and sports significantly predict mental health among university students. The (...) model explained 35.8% variance in mental health. The study suggests that PA and sports activity need to be promoted among university students to control prevailing mental health issues in adolescents. (shrink)

Philosophers intent upon characterizing the difference between physics and biology often seize upon the purported fact that physical explanations conform more closely to the covering law model than biological explanations. Central to this purported difference is the role of laws of nature in the explanations of these two sciences. However, I argue that, although certain important differences between physics and biology can be highlighted by differences between physical and biological explanations, these differences are not differences in the degree (...) to which those explanations conform to the covering law model, which fits biology about as well as it does physics.

In the absence of empirical confirmation, scientists may judge a theory's chances of being viable based on a wide range of arguments. The paper argues that such arguments can differ substantially with regard to their structural similarly to empirical confirmation. Arguments that resemble empirical confirmation in a number of crucial respects provide a better basis for reliable judgement and can, in a Bayesian sense, amount to significant \textit{non-empirical} confirmation. It is shown that three kinds of non- (...) class='Hi'>empirical confirmation that have been specified in earlier work do satisfy those conditions. (shrink)

Summary: The article explores deployment of the Darwinian narrative of the “natural history of humanity” in Russian physical anthropology in the late nineteenth to the early twentieth century. It traces two narratives developed by the leading Russian school of physical anthropology: one narrative advanced a universalist vision of collective scholarly enterprise working toward clarifying the missing links in the a priori accepted developmental evolutionary model. The other constructed a new language that undermined the idea of species/subspecies/races/nations/ as stable, externally bounded, (...) and internally homogeneous units and attempted to rationalize imperial hybridity. The article's main focus is on the latter classificatory narrative, its relational methodology, and the protostructuralist units of comparison that it produced. (shrink)

Nobel Laureate in physics Wolfgang Pauli studied philosophy and the history of ideas intensively, especially in his later years, to form an accurate ontology vis-à-vis quantum theory. Pauli's close contacts with the Swiss psychiatrist C.G. Jung gave him special qualifications for also understanding the basic problems of empirical knowledge. After Pauli's sudden death in 1958, this work was maintained mainly in his posthumously published correspondence, which so far extends only to 1939. Because Pauli's view differs essentially from the (...) direction physics research took after the deaths of the founding fathers of quantum theory, this article attempts to describe the main features in Pauli's revolutionary thought, which is based on nature's “epistemological lesson” as revealed by Pauli's atomic research. Pauli's conclusions have important implications for various issues in Western culture, not least with the limits of science and the relation of science to religion. (shrink)

The Empire of Chance tells how quantitative ideas of chance transformed the natural and social sciences, as well as daily life over the last three centuries. A continuous narrative connects the earliest application of probability and statistics in gambling and insurance to the most recent forays into law, medicine, polling and baseball. Separate chapters explore the theoretical and methodological impact in biology, physics and psychology. Themes recur - determinism, inference, causality, free will, evidence, the shifting meaning of probability - (...) but in dramatically different disciplinary and historical contexts. In contrast to the literature on the mathematical development of probability and statistics, this book centres on how these technical innovations remade our conceptions of nature, mind and society. Written by an interdisciplinary team of historians and philosophers, this readable, lucid account keeps technical material to an absolute minimum. It is aimed not only at specialists in the history and philosophy of science, but also at the general reader and scholars in other disciplines. (shrink)

Zusammenfassung Gleich mehrere Wissenschaftler gehen heute von der Annahme aus, dass Betriebe die soziale Integration ihrer neuen Mitarbeiter mit soziaüsationsfördernden Maßnahmen wie bspw. Sportprogrammen beeinflussen können. Dennoch wurde bislang weder in der Arbeits- und Organisationspsychologie noch in der Sportwissenschaft diese potentielle Wirkung empirisch untersucht. Ziel dieser kontrollierten, quasi-experimentellen Längsschnittstudie war es deshalb, den Einfluss einer zehnwöchigen Sportintervention auf die Freundschaftsnetzwerke und soziale Integration von 64 neuen Mitarbeitern zu untersuchen. Die Ergebnisse zeigen, dass sich die Netzwerkparameter bei der Kontrollgruppe im Zeitverlauf (...) kaum veränderten, wohingegen bei der Experimentalgruppe vor allem Größe, Umfang und Stärke deutlich zunahmen. Dennoch stellte sich nur beim Umfang eine signifikante Interaktion ein. Ein Einfluss auf die subjektiv wahrgenommene soziale Integration konnte nicht nachgewiesen werden. (shrink)

This paper develops a method for extracting from data the quantum theoretical state representation belonging to any reproducible empirical scheme for preparing a physical system, provided only that at least one observable has its possible values limited to a finite set. In Part I, we formulate a general systematic procedure, based on the concept of irreducible tensor operators, for the selection of sets of observables sufficiently large to permit the unambiguous determination of an unknown quantum state.

It is a platitude that thought implies a subject and an object: the subject is the thinker, or the thinking mind, and the object is that which is thought about. This is probably the most elementary fact of consciousness, comprehensible alike to the child, the unreflecting man of affairs, and the philosopher, and it forms the natural startingpoint for philosophy. And indeed, one of the great divisions between philosophical systems is that which separates subjectivism on one hand from objectivism on (...) the other. Subjectivism professes to interpret the object in terms of the subject, and objectivism professes to interpret the subject in terms of the object. (shrink)

This paper explores the scientific viability of the concept of causality—by questioning a central element of the distinction between “fundamental” and non-fundamental physics. It will be argued that the prevalent emphasis on fundamental physics involves formalistic and idealized partial models of physical regularities abstracting from and idealizing the causal evolution of physical systems. The accepted roles of partial models and of the special sciences in the growth of knowledge help demonstrate proper limitations of the concept of fundamental (...) class='Hi'>physics. We expect that a cause precedes its effect. But in some tension with this point, fundamental physical law is often held to be symmetrical and all-encompassing. Physical time, however, has not only measurable extension, as with spatial dimensions, it also has a direction—from the past through the present into the future. This preferred direction is time’s arrow. In spite of this standard contrast of time with space, if all the fundamental laws of physics are symmetrical, they are indifferent to time’s arrow. In consequence, excessive emphasis on the ideal of symmetrical, fundamental laws of physics generates skepticism regarding the common-sense and scientific uses of the concept of causality. The expectation has been that all physical phenomena are capable of explanation and prediction by reference to fundamental physicals laws—so that the laws and phenomena of statistical thermodynamics—and of the special sciences—must be derivative and/or secondary. The most important and oft repeated explanation of time’s arrow, however, is provided by the second law of thermodynamics. This paper explores the prospects for time’s arrow based on the second law. The concept of causality employed here is empirically based, though acknowledging practical scientific interests, and is linked to time’s arrow and to the thesis that there can be no causal change, in any domain of inquiry, without physical interaction.

Earlier in this century, many philosophers of science (for example, Rudolf Carnap) drew a fairly sharp distinction between theory and observation, between theoretical terms like 'mass' and 'electron', and observation terms like 'measures three meters in length' and 'is _2° Celsius'. By simply looking at our instruments we can ascertain what numbers our measurements yield. Creatures like mass are different: we determine mass by calculation; we never directly observe a mass. Nor an electron: this term is introduced in order to (...) explain what we observe. This (once standard) distinction between theory and observation was eventually found to be wanting. First, if the distinction holds, it is difficult to see what can characterize the relationship between theory :md observation. How can theoretical terms explain that which is itself in no way theorized? The second point leads out of the first: are not the instruments that provide us with observational material themselves creatures of theory? Is it really possible to have an observation language that is entirely barren of theory? The theory-Iadenness of observation languages is now an accept ed feature of the logic of science. Many regard such dependence of observation on theory as a virtue. If our instruments of observation do not derive their meaning from theories, whence comes that meaning? Surely - in science - we have nothing else but theories to tell us what to try to observe. (shrink)

This paper argues that a successful philosophical analysis of models and simulations must accommodate an account of mathematically rigorous results. Such rigorous results may be thought of as genuinely model-specific contributions, which can neither be deduced from fundamental theory nor inferred from empirical data. Rigorous results provide new indirect ways of assessing the success of models and simulations and are crucial to understanding the connections between different models. This is most obvious in cases where rigorous results map different models (...) on to one another. Not only does this put constraints on the extent to which performance in specific empirical contexts may be regarded as the main touchstone of success in scientific modelling, it also allows for the transfer of warrant across different models. Mathematically rigorous results can thus come to be seen as not only strengthening the cohesion between scientific strategies of modelling and simulation, but also as offering new ways of indirect confirmation.

Empires and nation-states are not opposed or distinct forms of polity but closely linked forms. Pre-modern empire existed without any contrasting form of polity we might call a nation-state. Rather, they contrasted with non-national state forms such as city-states, small kingdoms and mobile, nomadic polities. These in turn were in constant interaction with any neighbouring empire or empires, perhaps becoming the core of an empire themselves, perhaps taking over all or part of an existing empire, perhaps maintaining some autonomy by (...) virtue of remoteness or lack of attractiveness, perhaps by balancing opposed empires against each other. Empires did not have a national core, and non-empires were not national. By contrast, modern empires have always had a clearly designated nation-state core and a physically separate set of non-national peripheries. This has been crucial to ensuring that when formal empire is ended, both the imperial core and the former colonies are defined as nation-states. But ex-imperial nation-states and ex-colonial nation-states are really two kinds of states. Much contemporary confusion about the prospect for a world order of nation-states revolves round the failure to make that basic distinction. (shrink)

The study of child abuse and child homicide has been based on the often implicit assumption that there is a continuum of violence ranging from mild physical punishment to severe abuse and homicide. Empirical data supporting this assumption are sparse. Existing data can be shown, however, to support an assumption that there are distinct forms of violence, not a continuum. This paper reviews these data and discusses their implications for the study of violence, abuse, and homicide in terms of (...) substantive and methodological explanations. In addition, the implications of the assumption that violence consists of distinct behaviors as opposed to a continuum are discussed in light of sociobiological and evolutionary explanations of child abuse and child homicide.

This article proposes an empirical approach to understanding the life of an organism that overcomes reductionist and dualist approaches. The approach is based on Immanuel Kant’s analysis of the cognitive conditions required for the recognition of an organism: the concept of teleology and the assumption of a formative power of self-generation. It is analyzed how these two criteria are applied in the cognition of a developing organism. Using the example of a developmental series of a plant leaf, an active (...) and relational process between observer and developing organism is shown, within which the teleology and self-generating power of the organism can be empirically observed through the mental faculties of understanding and will. Furthermore, it is emphasized that, according to Kant, even physical objects are not readily given, but are actively constituted through the unification of sense perceptions with concepts. This Kantian mode of objectification facilitates cognition of the physical properties of an organism. It can be supplemented with a participatory and co-constitutive mode of realization, in which the life of the organism (its teleologically organizing and self-generating power) can become an object of empirical research. Furthermore, it is argued that the participatory mode also facilitates an expanded conception of nature that allows for the existence of living beings within it. Finally, an analogy to Goethe’s approach to the living organism is highlighted. In summary, it is stated that to understand life, one must consciously participate in it. (shrink)

I outline an intrinsic (coordinate-free) formulation of classical particle mechanics, making no use of set theory or second-order logic. Physical quantities are accepted as real, but are constrained only by elementary axioms. This contrasts with the formulations of Field and Burgess, in which space-time regions are accepted as real and are assumed to satisfy second-order comprehension axioms. The present formulation is both logically simpler and physically more realistic. The theory is finitely axiomatizable, elementary, and even quantifier-free, but is provably empirically (...) equivalent to the standard coordinate formulations. (shrink)

Here, we offer concrete illustrations of the state determination method developed abstractly in Part I of this work. Quorums are found for finite-dimensional magnetic multipole problems as well as for the harmonic oscillator with an energy cutoff. There is, in addition, a discussion of general procedures for empirically distinguishing pure states from mixed states.

It is argued that certain quantum theories of gravity — string theory, loop quantum gravity, non-commutative field theory — do not include spacetime as part of their fundamental ontology. There is a concern in the literature that theories of this kind are physically opaque and empirically incoherent. In this paper, I clarify and amend Huggett and Wüthrich’s argument against these claims. Whereas the content of this paper centres on the disappearance and re-emergence of spacetime in quantum gravity, much of the (...) philosophical work centres more generally on issues of (emergent) ontology and how this ontology can be extracted from formal theories, the role of formal derivations in justifying ontological relations, the nature of Kuhnian revolutions, and the application of these revolutions to quantum gravity.

It is widely recognized that ‘global’ symmetries, such as the boost invariance of classical mechanics and special relativity, can give rise to direct empirical counterparts such as the Galileo-ship phenomenon. However, conventional wisdom holds that ‘local’ symmetries, such as the diffeomorphism invariance of general relativity and the gauge invariance of classical electromagnetism, have no such direct empirical counterparts. We argue against this conventional wisdom. We develop a framework for analysing the relationship between Galileo-ship empirical phenomena on the (...) one hand, and physical theories that model such phenomena on the other, that renders the relationship between theoretical and empirical symmetries transparent, and from which it follows that both global and local symmetries can give rise to Galileo-ship phenomena. In particular, we use this framework to exhibit an analogue of Galileo’s ship for the local gauge invariance of electromagnetism. 1 Introduction2 Analogues of Galileo’s Ship?

Phenomenal intentionality is a singular form of intentionality. Science shows it is internally-determined. So standard externalist models for reducing intentionality don't apply to it.

Does physics describe anything that can meaningfully be called “independent reality,” or is it merely operational? Most physicists implicitly favor an intermediate standpoint, which takes quantum physics into account, but which nevertheless strongly holds fast to quite strictly realistic ideas about apparently “obvious facts” concerning the macro-objects. Part 1 of this article, which is a survey of recent measurement theories, shows that, when made explicit, the standpoint in question cannot be upheld. Part 2 brings forward a proposal for (...) making minimal changes to this standpoint in such a way as to remove such objections. The “empirical reality” thus constructed is a notion that, to some extent,does ultimately refer to the human means of apprehension and of data processing. It nevertheless cannot be said that it reduces to a mere name just labelling a “set of recipes that never fail.” It is shown that our usual notion of macroscopic causality must be endowed with similar features.

One of the important areas of study of religious psychology is to examine the reflection of worship in the spiritual life of individuals in the context of worship psychology. In this field survey, the relations between the level of meaning in life and hopelessness of individuals who performed the ʿUmra worship are examined. The study is conducted with 214 Turkish participants who performed ʿumra in Saudi Arabia. The collected data is analyzed by questionnaire technique. "Personal Information Form", " Meaning in (...) Life Questionnaire (MLQ)" and "Beck Hopelessness Scale" are used as data collection tools. The obtained data is analyzed in the SPSS 23.0 statistical program. One Sample t-Test, Pearson Moments Multiplication Correlation Analysis, Independent Sampling t-Test, One Way ANOVA and Tukey HSD tests are used to analyse the data. It is found that the research group's level of meaning in life above average; the level of hopelessness is below average significantly. There is a significant negative correlation between meaning in life and hopelessness, feelings about the future, loss of motivation, expectation about the future. There is a significant positive correlation between searched meaning and hopelessness and loss of motivation.Summary: Many religions have some types of worship involving visiting places considered as sacred and performing some rituals there. In Islam it is called ʿUmra, which is visiting the Kaʿba without being dependent on a certain time frame except for the pilgrimage month. There are certain rites to perform ʿumra, such as entering a state of iḥrām (ritual purity in which certain actions are not permissible), completing circumambulation, and saʿy (striving to do a certain act; walking) between the hills of al-Ṣafā and al-Marwa. ʿUmra worship is a comprehensive and versatile worship, which contains psychological, sociological, physical and financial characteristics.Studying the relationship between religious beliefs and practices, the religious rituals and their psychological effects and functions of ceremonies are the some essential research topics of Psychology of Religion. Existing research in this area usually reveals the existence of a positive relationship between the religious beliefs and practices and between meaning in life and hope. Individuals who believe in a religion can find a meaning and purpose in life through prayer and worship, and at the same time have more positive future expectation to endure the difficulties of life. Meaning and hope are intertwined, which complete each other. Hopelessness is closely related to depression and suicidal desire. There is a need to find meaning and purpose in life in order to hold on to life, and for looking to the future with confidence, and overcoming difficulties.It is known that people tend to be more religious and concentrating worship during periods of loss of meaning for various reasons. ʿUmra, which includes almost all type of worship, is a special worship, which has the potential to contribute to the individual's intense emotional life for gaining new awareness and developing different behaviours to cope with such difficulties. It is because the individual would have many experiences to see the cause of existence, the meaning of his/her life, and his/her future expectation during the ʿumra worship. Thus, he/she can overcome his/her hopelessness and loss of meaning and look to the situation from different perspectives. Therefore, in this study, the following questions are explored: Does ʿumra make a positive contribution to the psychological experience of the individuals, as expected? Does ʿumra has any effect on the level of loss of meaning and hopelessness that accompanies the psychological troubles? How does the demographic variables make difference in the level of meaning in life and hopelessness of individuals who perform ʿumra? In order to find answers to these questions, the relationship between the meaning of life - the hopelessness and the ʿumra was investigated. For this purpose, the meaning and hopelessness levels of the individuals who are performing ʿumra worship were measured by psychometric methods and the relations between them were analyzed. In addition, it has been tested whether there is a difference in the meaning in life and hopelessness according to demographic variables such as gender, marital status and educational status. 214 people aged between 18-82 years participated in the research. The survey data was collected from Turkish participants who perform ʿumra in the cities of Mecca and Medina in Saudi Arabia in May 2015. "Personal Information Form", " Meaning in Life Questionnaire (MLQ)" and "Beck Hopelessness Scale" were used as data collection tools. The obtained data were analyzed in the SPSS 23.0 statistical program. One Sample t-Test, Pearson Moments Multiplication Correlation Analysis, Independent Sampling t-Test, One Way ANOVA and Tukey HSD tests were used for the purpose of analysis of the data.The most important finding of the survey is meaning in life scores of individuals who are performing the ʿumra are above average (t = 20,50; p ˂ 0,01); and scores of hopelessness are below average significantly (t = -29,80; p ˂0,01). There is a significant negative correlation between presence of meaning subscale and hopelessness (r = -,288; p ˂ 0,01); and positive correlation between search for meaning subscale and hopelessness (r =,169; p ˂ 0,05) and loss of motivation (r =,285; p ˂ 0,01). The findings show that ʿumra can affect the meaning in life positively and the hopelessness negatively. There was no significant difference between the meaning in life scores and education level and gender variable (p ˃ 0,05). As the level of education increases, hopelessness scores decrease significantly (F = 2, 627; p ˂ 0,05). Hopelessness scores show a significant difference according to gender (t = -2,708; p ˂ 0,01). Men's hopelessness levels are significantly higher than women’s. Moreover, the meaning in life of married individuals is significantly higher than single individuals (F = 3,859; p ˂ 0,05). As the age and developmental stages progressed, meaning in life (F = 7,274; p ˂ 0,01) and hopelessness scores (F = 8,119; p ˂ 0,01) significantly increased.ʿUmra may have a rapid and intensive effect on the psychology of the individual and his/her sense of world. Relevant studies in the literature also imply such results. Since ʿumra is both a journey and a collective worship, it involves many types of worship, such as praying, reading scripture, repentance and so on. The findings of this study were discussed with reference to the findings about pilgrimage and the findings of study of meaning in life and hopelessness in different samples. On the other hand, the conditions in which the data collected, the study group chosen, the instruments and techniques used for this research constitute the limitations of the present study. However, the time period in which the worship was practiced and reaching the participants in these places of worship, and the measurement of the level meaning in life and hopelessness associated with their worship of ʿumra indicates the importance and originality of this research. The results can be used in other research projects. Studies on the different psychological effects of ʿumra worship can be enriched by longitudinal investigations. (shrink)

Contrary to claims about the irrelevance of philosophy for science, I argue that philosophy has had, and still has, far more influence on physics than is commonly assumed. I maintain that the current anti-philosophical ideology has had damaging effects on the fertility of science. I also suggest that recent important empirical results, such as the detection of the Higgs particle and gravitational waves, and the failure to detect supersymmetry where many expected to find it, question the validity of (...) certain philosophical assumptions common among theoretical physicists, inviting us to engage in a clearer philosophical reflection on scientific method.

The concept of “representation” is used broadly and uncontroversially throughout neuroscience, in contrast to its highly controversial status within the philosophy of mind and cognitive science. In this paper I first discuss the way that the term is used within neuroscience, in particular describing the strategies by which representations are characterized empirically. I then relate the concept of representation within neuroscience to one that has developed within the field of machine learning. I argue that the recent success of artificial neural (...) networks on certain tasks such as visual object recognition reflects the degree to which those systems exhibit inherent inductive biases that reflect the structure of the physical world. I further argue that any system that is going to behave intelligently in the world must contain representations that reflect the structure of the world; otherwise, the system must perform unconstrained function approximation which is destined to fail due to the curse of dimensionality, in which the number of possible states of the world grows exponentially with the number of dimensions in the space of possible inputs. An analysis of these concepts in light of philosophical debates regarding the ontological status of representations suggests that the representations identified within both biological and artificial neural networks qualify as legitimate representations in the philosophical sense.

This paper examines the relationship between physical theories of causation and theories of difference-making. It is plausible to think that such theories are compatible with one another as they are aimed at different targets: the former, an empirical account of actual causal relations; the latter, an account that will capture the truth of most of our ordinary causal claims. The question then becomes: what is the relationship between physical causation and difference-making? Is one kind of causal fact more fundamental (...) than the other? This paper defends causal foundationalism: the view that facts about difference-making are dependent on the obtaining of facts about physical causation. However, the paper's main goal is to clarify the structure of the debate. At the end of the paper, it is shown how settling the issue about the relationship between physical theories of causation and theories of difference-making has more than mere intrinsic interest in unifying the very different pursuits that have been undertaken in the philosophy of causation. It can help to break a stalemate that has arisen in the current debate about mental causation. (shrink)

The article proposes a novel approach to the much discussed question of which symmetries have ‘direct empirical significance’ and which do not. The approach is based on a development of a recently proposed framework by Hilary Greaves and David Wallace, who claim that, contrary to the standard folklore among philosophers of physics, ‘local’ symmetries may have direct empirical significance no less than ‘global’ ones. Partly vindicating the standard folklore, a result is derived here from a number of (...) plausible assumptions, that states that local symmetries can indeed have no direct empirical significance. Ways to interpret the result are considered and possible morals are outlined. 1 Introduction2 Greaves and Wallace on Interior versus Non-interior Symmetries3 Elaborating on the Greaves/Wallace Framework4 The Result5 Problems with ’t Hooft’s Beam Splitter6 Summary and Conclusion.

This paper explores the options available to the anti-realist to defend a Quinean empirical under-determination thesis using examples of dualities. I first explicate a version of the empirical under-determination thesis that can be brought to bear on theories of contemporary physics. Then I identify a class of examples of dualities that lead to empirical under-determination. But I argue that the resulting under-determination is benign, and is not a threat to a cautious scientific realism. Thus dualities are (...) not new ammunition for the anti-realist. The paper also shows how the number of possible interpretative options about dualities that have been considered in the literature can be reduced, and suggests a general approach to scientific realism that one may take dualities to favour.

Assyria can be described as the founder of the imperial model of kingship in the ancient Near East. The Assyrian court itself, however, remains poorly understood. Scholarship has treated the court as a disembodied, textual entity, separated from the physical spaces it occupied – namely, the palaces. At the same time, architectural analyses have examined the physical structures of the Assyrian palaces, without consideration for how these structures were connected to people’s lives and works. The palaces are often described as (...) secluded, inaccessible locations. This study presents the first model of the Assyrian court contextualized in its actual palaces. It provides a nuanced model highlighting how the court organized the immense flow of information, people and goods entering the palace as a result of the empire’s increased size and complexity. It argues that access to the king was regulated by three gates of control which were manned by specific types of personnel and a more situational organization that moved within the physical spaces of the palace and was contingent on the king’s activity.

Mental health is a kind of emotional state, a good psychological state can have a positive impact on a person, physical exercise can have a positive impact on the psychological state of college students, prevent the generation of negative emotions, improve the bad emotional state, and then promote the mental health of college students. Health is an inevitable requirement to promote the all-round development of people and a basic condition for economic and social development. Health education should be incorporated into (...) the national education system to promote the national health of the people through sports. Young people are the main force and backbone of national and social development. In order to realize the Chinese dream of great rejuvenation, we must attach importance to the development of young people and the physical and mental health of young people. In the process of compulsory education, middle school and high school period is a key stage in the gradual formation and development of students' psychology and body, but due to the large audience of China's education, the competition is more intense, which inevitably causes a lot of students to focus on exam-oriented education and neglect physical health, especially in recent years, the mental health issues of increasing concern. Through the research situation of mental health in China and the concept of mental health quality, this paper analyzes the problems of sports and mental health, and puts forward some corresponding suggestions for the problems, which has reference significance for promoting students' mental health.

It is usual to identify initial conditions of classical dynamical systems with mathematical real numbers. However, almost all real numbers contain an infinite amount of information. I argue that a finite volume of space can’t contain more than a finite amount of information, hence that the mathematical real numbers are not physically relevant. Moreover, a better terminology for the so-called real numbers is “random numbers”, as their series of bits are truly random. I propose an alternative classical mechanics, which is (...) empirically equivalent to classical mechanics, but uses only finite-information numbers. This alternative classical mechanics is non-deterministic, despite the use of deterministic equations, in a way similar to quantum theory. Interestingly, both alternative classical mechanics and quantum theories can be supplemented by additional variables in such a way that the supplemented theory is deterministic. Most physicists straightforwardly supplement classical theory with real numbers to which they attribute physical existence, while most physicists reject Bohmian mechanics as supplemented quantum theory, arguing that Bohmian positions have no physical reality.
