In the course of his long development, Kant's concept of matter changed somewhat, while his concept of scientific explanation changed considerably. Both developments achieved a coherent integration in Kant's Metaphysical Foundations of Natural Science. Using this developmental background, the present paper argues that the Foundations should be interpreted as an attempted rational reconstruction of the mechanics of Newton and Euler. Kant attempted to do this by constructing a concept of matter that would confer a Leibnizian intelligibility on Newtonian mechanics, and (...) also accord with Kant's theories on the nature of concepts and their role in scientific explanation.

There are two opposing traditions in contemporary quantum field theory (QFT). Mainstream Lagrangian QFT led to and supports the standard model of particle interactions. Algebraic QFT seeks to provide a rigorous consistent mathematical foundation for field theory, but cannot accommodate the local gauge interactions of the standard model. Interested philosophers face a choice. They can accept algebraic QFT on the grounds of mathematical consistency and general accord with the semantic conception of theory interpretation. This suggests a rejection of particle ontology. (...) Or they can accept the standard model on the grounds of its established success. This alternative, which I defend, suggests revising philosophical accounts of scientific theory and finding some way of accommodating particles. (shrink)

In place of earlier instrumentalist and phenomenalist interpretations of science both Quine and Sellars have developed highly influential realist positions centering around the doctrine that accepting a theory as explanatory and irreducible rationally entails accepting the entities posited by the theory. A growing reaction against this realism is partially based on perceived inadequacies in the doctrines of Quine and Sellars, but even more on reconstructions of scientific explanations which do not involve such ontic commitments. Three types of anti-realistic positions are (...) considered and criticized. Hesse's neo-Duhemian position couples a statistical theory of inference to a downgrading of purely theoretical statements. Sneed uses the method of axiomatrization through set-theoretic predicates to supply a reconstruction of Kuhn's account of scientific development. Here Ramsey-reduction sentences serve to eliminate purely theoretical terms. The longest section deals with van Fraassen's semantic model based on a state-space representation of scientific theories and the use of this model in interpreting quantum mechanics. It is argued that the model is valuable, but that the anti-realist interpretation accorded it is not justified and entails serious inconsistencies. (shrink)

This book is the first to offer a systematic account of the role of language in the development and interpretation of physics. An historical-conceptual analysis of the co-evolution of physics and mathematics leads to the classical/quantum interface. Bohr's interpretation is analyzed and extended to the interpretation of the standard model of particle physics.

This article argues that the Universal Declaration of Human Rights, by claiming certain inheritances from eighteenth-century American and French rights declarations, simultaneously disavowed others, reshaping the genre of the rights declaration in ways amenable to forms of imperial and racial domination. I begin by considering the rights declaration as genre, arguing that later participants can both inherit and disavow aspects of what came before. Then, drawing on original archival research, I consider the drafting of the UDHR, using as an entry (...) point the reception of the NAACP’s Appeal to the World petition, edited by W.E.B. DuBois. I reconstruct conversations within the drafting committee about the right to petition, self-determination, and the right to rebellion, and the separation of the Declaration from the rights covenants, to illustrate the allegiances between US racial politics and French imperial politics, and their legacies for our contemporary conceptions of human rights.

An epistemological interpretation of quantum mechanics hinges on the claim that the distinctive features of quantum mechanics can be derived from some distinctive features of an observational basis. Old and new variations of this theme are listed. The program has a limited success in non-relativistic quantum mechanics. The crucial issue is how far it can be extended to quantum field theory without introducing significant ontological postulates. A C*-formulation covers algebraic quantum field theory, but not the standard model. Julian Schwinger’s anabatic (...) methodology extended a strict measurement-based formulation of quantum mechanics through field theory. His extension also excluded the quark hypothesis and the standard model. Quarks and local gauge invariance are postulates that go beyond the limits of an epistemological interpretation of quantum mechanics. The ontological significance ascribed to these advances depends on the role accorded ontology. (shrink)

It is assumed that the motion of a particle in spacetime does not depend on the motion relative to it of any observer or of any frame of reference. Thus if the particle has an internal vibration of the type hypothesized by de Broglie, the phase of that vibration at any point in spacetime must appear to be the same to all observers, i.e., the same in all frames of reference. Each observer or reference frame will have its own de (...) Broglie wave for the particle. The phase of the particle's vibration must, by definition, be the same as that of all possible de Broglie waves at the point where the particle is. By superimposing all these possible de Broglie waves, a wave packet is formed centered in space on the particle. The formation of such a packet is discussed with the help of spacetime diagrams; the packet does not spread with time. The relevance of this packet to the wave mechanics of Schrödinger is discussed; it is also pointed out that any vibration can lead to such a packet. (shrink)

This paper argues that existence claims for theoretical entities must be based on more than their role in one theory. The supplementary evidence should be either observation, whether direct or indirect, or the possibility of detaching the existence claim from one particular theory. A logical schematism for the latter type of support is developed.

This article probes the question of what interpretations of quantum mechanics actually accomplish. In other domains, which are briefly considered, interpretations serve to make alien systematizations intelligible to us. This often involves clarifying the status of their implicit ontology. A survey of interpretations of non-relativistic quantum mechanics supports the evaluation that these interpretations make a contribution to philosophy, but not to physics. Interpretations of quantum field theory are polarized by the divergence between the Lagrangian field theory that led to the (...) Standard Model of Particle physics and the Algebraic quantum field theory, that discounts an ontology of particles. Ruetsche's interpretation, it is argued, offers a potential for loosening the sharp polarization that presently obtains. A brief evaluation focuses on the functional ontology of quantum field theory considered as an effective theory. (shrink)

This article clarifies Bohr's position by focusing on the work he did in nuclear physics and scattering theory.

The consistent histories reformulation of quantum mechanics was developed by Robert Griffiths, given a formal logical systematization by Roland Omn\`{e}s, and under the label `decoherent histories', was independently developed by Murray Gell-Mann and James Hartle and extended to quantum cosmology. Criticisms of CH involve issues of meaning, truth, objectivity, and coherence, a mixture of philosophy and physics. We will briefly consider the original formulation of CH and some basic objections. The reply to these objections, like the objections themselves, involves a (...) mixture of physics and philosophy. These replies support an evaluation of the CH formulation as a replacement for the measurement, or orthodox, interpretation. (shrink)

Rom Harré's proposed Copernican Revolution in the philosophy of science is a very ambitious undertaking. It challenges established views, proposes a radically new model for scientific explanation, and forces a rethinking of the foundations of the field. In his treatment of the natural sciences, Harré rejects all deductivist accounts of scientific explanation basically on the grounds that such accounts seriously distort the methods of explanation actually operative in science. In the social sciences Harré, in collaboration with Secord, rejects mechanistic, positivistic, (...) and behavioristic accounts of human behavior [5]. In place of these discarded interpretations he substitutes a new realism which stresses the role that models play in supplying accounts of observed patterns of phenomena in terms of the things and processes whose interactions are responsible for the manifest phenomena. This revolution, if successfully carried out, would indeed be a valuable contribution to the philosophy of science. (shrink)

It was in 1792 that Kant published the first Book of his most important single work on the philosophy of religion—Religion within the Limits of Reason Alone. But it was his very interesting treatment of the biblical material in the second Book that involved the philosopher in his one serious conflict with official authority. Greene and Hudson give a good account of this conflict and its effect on the work as a whole in the introduction to their translation of Religion (...) in the Harper Torchbook Series. (shrink)

Niels Bohr began his career with an attempt to give a correct descriptive account of the motion of electrons. When forced to abandon this interpretation, he adopted, but soon rejected, a hypothetical-deductive account. In his development of an interpretation for the new quantum theory Bohr began to concentrate on the way language functions to make descriptions possible. His later work on this problem and on the role of concepts in the foundations of science led him to anticipate some of the (...) basic ideas developed in Wittgenstein's Investigations. Bohr eventually saw his own analysis of the conditions of the possibility of unambiguous communication as the basis for making explicit the unity implicit in science. (shrink)

Aims and background: Little is known about how participants perceive prevention trials, particularly trials designed to prevent mental illness. This study examined participants’ motives for participating in a trial and their views of randomisation and the ability to withdraw from a randomised controlled trial for prevention of depression. Methods: Participants were older adults reporting elevated depression symptoms living in urban and regional locations in Australia who had consented to participate in an RCT of interventions to prevent depression. Participants rated their (...) agreement with various statements describing motivations for enrolment in the trial and opinions regarding randomisation and withdrawal. Results: The majority of participants expressed a triad of altruistic motivation for participation, relative lack of concern about randomisation and commitment to the trial. Certain subgroups of participants, such as women and those with higher depression scores, reported higher levels of concern about specific issues. Conclusions: The findings suggest that participants enrolled in prevention trials for mental illness are likely to hold positive attitudes towards research trials. The identification of relationships between key person factors and trial-related attitudes enabled profiling of participant groups, which can inform recruitment strategies and interactions of participants and research projects in future prevention trials.

Anorexia Nervosa (AN) is widely considered to be a bodily disorder accompanied by unrealistic perceptions about one’s own body. Some researchers thus have wondered whether deficits in interoception, a conscious or non-conscious sense of one’s own body, could be a primary cause of AN. In this paper, we make the case that rather than interoception being a primary cause, deficits in interoception may occur as by-products of emotions that arise upstream in the pathogenesis of AN and interact with feelings of (...) a loss of self-control. We consider interoception, emotion, and self-control as a dynamical triad involved in the explanation of AN, with emotions as the central aspect of their interactions. We begin with a critical analysis of recent empirical literature on AN and differentiate three types of interoceptive processes. We then consider the role of self-control in AN. We go on to evaluate recent empirical and philosophical work on the role of emotions in AN and assess their importance in both interoception and self-control dynamics. We develop a testable integrative model that we believe best captures how self-control, emotional and interoceptive processes causally interact in the pathogenesis of AN. In this model, AN behaviors are not caused by interoceptive abnormalities, but rather interact with changes in emotional regulation and feelings of loss of self-control, subsequently leading to interoceptive deficits downstream. To capture a later stage in the pathogenesis of AN, we show how AN behaviors are maintained as a result of feedback among components in the model. We briefly explain future plans to further complement the model using a semi-structured interview to probe patient perspectives in AN. To develop a more valid understanding of AN, this model will have to be integrated into pluralistic approaches that include patient perspectives. (shrink)

Changes to practical nurse education (with expanded scopes of practice) align with the increasing need for nurses and assistive personnel in global acute care contexts. A case in point is this critical exploration of Canadian practical nursing literature, undertaken to reveal predominating discourses and relationships to nursing disciplinary knowledge. The objectives of this poststructural critical review were to identify dominant discourses in practical nurse education literature and to analyze these discourses to uncover underlying beliefs, constructed truths, assumptions, ambiguities and sources (...) of knowledge within the discursive landscape. Predominant themes in the discourses surrounding practical nurse education included conversations about the nurse shortage, expanded roles, collaboration, evidence‐based practice, role confusion, cost/efficiency, the history of practical nurse education and employer interests. The complex relationships between practical nursing and the disciplinary landscape of nursing are revealed in the analysis of discourses related to the purpose(s) of practical nurse education, curricula/educational programming, relationships between RN and PN education and the role of nursing knowledge. Power dynamics related to employer needs and interests, as well as educational silos and the nature of women's work, are also revealed within the intersection of various discourses. (shrink)

The tension that many early scientists experienced between a reliance on religious tradition as a source of truth and scientific methodology as a guide to truth eventually led to a clash between theists who claimed that the existence of the universe required a creator and non-theists, who insisted that recourse to a creator to explain why there is something perverts scientific methodology. The present paper defends the position that physics and its foreseeable cosmological extensions neither requires nor excludes either opposed (...) contention. Each has the status of an inference to the best explanation. This is developed in three stages. The first uses historical analysis to support the claim that the advancement of physics and cosmology do not rely on an appeal to supernatural forces. The second explains inference to the best explanation. The third shows how this accommodates these conflicting claims. An appendix examines an influential argument that the intelligibility of the universe requires a creator. (shrink)
