Patrick Aidan Heelan’s The Observable offers the reader a completely articulated development of his 1965 philosophy of quantum physics, Quantum Mechanics and Objectivity. In this previously unpublished study dating back more than a half a century, Heelan brings his background as both a physicist and a philosopher to his reflections on Werner Heisenberg’s physical philosophy. Including considerably broader connections to the contributions of Niels Bohr, Wolfgang Pauli, and Albert Einstein, this study also reflects Heelan’s experience in (...) Eugene Wigner’s laboratory at Princeton along with his reflections on working with Erwin Schrödinger dating from Heelan’s years at the Institute for Advanced Cosmology in Dublin. A contribution to continental philosophy of science, the phenomenological and hermeneutic resources applied in this book to the physical and ontological paradoxes of quantum physics, especially in connection with laboratory science and measurement, theory and model making, will enrich students of the history of science as well as those interested in different approaches to the historiography of science. University courses in the philosophy of physics will find this book indispensable as a resource and invaluable for courses in the history of science. (shrink)

Hermeneutics, or interpretation, is concerned with the generation, transmission, and acceptance of meaning within the lifeworld, and was the original method of the human sciences stemming, from F. Schleiermacher and W. Dilthey. The `hermeneutic philosophy' refers mostly to Heidegger. This paper addresses natural science from the perspective of Heidegger's analysis of meaning and interpretation. Its purpose is to incorporate into the philosophy of science those aspects of historicality, culture, and tradition that are absent from the traditional analysis of theory and (...) explanation, to re-orient the current discussion about scientific realism around the hermeneutics of meaning and truth in science, and to establish some relationship between the current philosophy of natural science and hermeneutical philosophy. The paper has particular relevance to the history and social studies of science and technology. (shrink)

My scientific field is theoretical physics. My philosophical orientation is phenomenology, especially hermeneutical phenomenology, as modified and extended under the influence of Bernard Lonergan's cognitional theory. In fact, I was already deeply under the influence of Bernard Lonergan's workbefore I went to Louvain/Leuven to study phenomenology as a propaedeutic to my preparation in the philosophy of science. The specific topic of this paper is one close to the center of Philip's interest, namely, to articulate the right balance among theory, experiment, (...) and what Husserl called 'die Sache selbst' or the 'givenness' of scientific objects as experienced and understood. The method I shall adopt is that of Husserl's phenomenology of perception, as modified by Lonergan's method of 'self-appropriation.' I will be concerned then with the 'constitution' of experimental data in science - any science. (shrink)

Why a hermeneutical philosophy of the natural sciences? It is necessary to address the philosophic crisis of realism vs relativism in the natural sciences. This crisis is seen as a part of the cultural crisis that Husserl and Heidegger identified and attributed to the hegemonic role of theoretical and calculative thought in Western societies. The role of theory is addressed using the hermeneutical circle to probe the origin of theoretic meaning in scientific cultural praxes. This is studied in Galileo's discovery (...) of the phases of Venus; the practice of measurement; the different theories and practices of space perception; the historicality and temporality of scientific research communities which ground paradigm change; and the process of discovery. The paper draws particularly from the work of Heidegger. Though envisaging all science and scholarship, the highlighted theme is research in the natural sciences. (shrink)

The author proposes the thesis that all perception, including observation in natural science, is hermeneutical as well as causal; that is, the perceiver (or observer) learns to 'read' instrumental or other perceptual stimuli as one learns to read a text. This hermeneutical aspect at the heart of natural science is located where it might be least expected, within acts of scientific observation. In relation to the history of science, the question is addressed to what extent the hermeneutical component within scientific (...) observation opens natural science to the charge of reflecting merely cultural values, and of providing merely a culturally acceptable reading of the "Book of Nature", rather than, as the author states, one stating universal antecedent conditions of possibility of cultural activity itself.

Quantum mechanics has raised in an acute form three problems which go to the heart of man's relationship with nature through experimental science: (r) the public objectivity of science, that is, its value as a universal science for all investigators; (2) the empirical objectivity of scientific objects, that is, man's ability to construct a precise or causal spatio-temporal model of microscopic systems; and finally (3), the formal objectivity of science, that is, its value as an expression of what nature is (...) independently of its being an object of human knowledge. These are three aspects of what is generally called the "crisis of objec tivity" or the "crisis of realism" in modern physics. This crisis is. studied in the light of Werner Heisenberg's work. Heisenberg was one of the architects of quantum mechanics, and we have chosen his writings as the principal source-material for this study. Among physicists of the microscopic domain, no one except perhaps Bohr has expressed himself so abundantly and so profoundly on the philosophy of science as Heisenberg. His writings, both technical and non-technical, show an awareness of the mysterious element in scientific knowledge, far from the facile positivism of Bohr and others of his contemporaries. The mystery of human knowledge and human SUbjectivity is for him an abiding source of wonder. (shrink)

This richly textured book bridges analytic and hermeneutic and phenomenological philosophy of science. It features unique resources for students of the philosophy and history of quantum mechanics and the Copenhagen Interpretation, cognitive theory and the psychology of perception, the history and philosophy of art, and the pragmatic and historical relationships between religion and science.

Two philosophical traditions with much in common, (classical) pragmatism and (Heidegger's) hermeneutic philosophy, are here\ncompared with respect to their approach to the philosophy of science. Both emphasize action as a mode of interpreting experience.\nBoth have developed important categories – inquiry, meaning, theory, praxis, coping, historicity, life-world – and each has\noffered an alternative to the more traditional philosophies of science stemming from Descartes, Hume, and Comte. Pragmatism's\nabduction works with the dual perspectives of theory (as explanation) and praxis (as culture). The hermeneutical (...) circle depends\nin addition on the lifeworld as background source of ontological meaning and resource for strategies of inquiry. Thus a hermeneutical\nphilosophy of research involves three components: lifeworld (as ontological and strategic), theory (as explanatory), and praxis\n(as constitutive of culture). (shrink)

Husserl argues in the Crisis that the prevalent tradition of positive science in his time had a philosophical core, called by him "Galilean science", that mistook the quest for objective theory with the quest for truth. Husserl is here referring to Gottingen science of the Golden Years. For Husserl, theory "grows" out of the "soil" of the prescientific, that is, pretheoretical, life-world. Scientific truth finally is to be sought not in theory but rather in the pragmatic-perceptual praxes of measurement. Husserl (...) is faulted for taking measuring processes to be "infinitely perfectible". The dependence of new scientific phenomena on the existence of prior "prescientific" inductive praxis is analyzed, also Husserl's residual objectivism and failure to appreciate the hermeneutic character of measurement. Though not a scientific (theory-)realist, neither was he an instrumentalist, but he was a scientific (phenomena-)realist. (shrink)

IN A recent work I have attempted to show that visual space tends to have a Euclidean geometrical structure only when the environment is filled with a repetitive pattern of regularly faceted objects carpentered to exhibit simple standard Euclidean shapes, and tends to have a hyperbolic structure when vision is deprived of these clues. I conclude that visual perception--and by analogy, all perception--is hermeneutic as well as causal: it responds to structures in the flow of optical energy, but the character (...) of its response is also hermeneutical, that is, it has the capacity to "read" the appropriate structures in the World, and to form perceptual judgments of the World about which these "speak." The clues that are "read" perceptually as giving a Euclidean visual space are engineered objects, such as streets and buildings with repetitive architectural elements. These scientific artifacts of human culture belong to a family of readable technologies central to the phenomenological and existential-hermeneutical analysis of natural science. (shrink)

Quantum-mechanical event descriptions are context-dependent descriptions. The role of quantum (nondistributive) logic is in the partial ordering of contexts rather than in the ordering of quantum-mechanical events. Moreover, the kind of quantum logic displayed by quantum mechanics can be easily inferred from the general notion of contextuality used in ordinary language. The formalizable core of Bohr's notion of complementarity is the type of context dependence discussed in this paper.

Heisenberg, in constructing quantum mechanics, explicitly followed certain principles exemplified, as he believed, in Einstein's construction of the special theory of relativity which for him was the paradigm for radical theoretic change in physics. These were the principles of scientific realism, stability of background knowledge, E-observability, contextual re-interpretation, pragmatic continuity, model continuity, simplicity. Fifty years later, in retrospect, Heisenberg added the following two: a principle of non-proliferation of competing theories - scientific revolutions are not a legitimate goal of physics - (...) and a principle of tenacity - existing theories are to be conserved as far as possible. The conservative as well as the revolutionary potential of these principles is then discussed. A more penetrating philosophical criticism of these principles is postponed. (shrink)

The ArgumentIn this rejoinder to Gyorgy Markus, I argue that although there are nonphilosophical hermeneutical studies of communication among scientists from which much can be learned about scientific practices, there is also the philosophical genre of a hermeneutics of natural science, with which this paper is concerned. The former is the nonphilosophical use of hermeneutics in the study of texts and historical sources; the latter is a philosophy pursued within a working canon of philosophical works defined principally by the writings (...) of Heidegger and Husserl. There is also a hermeneutically sensitive analytic philosophy of science, such as in the work of Kuhn, Toulmin, and Elkana. These genres are distinguished by their literary canons and their basic phenomenologies or critical experiential givens; each genre comprises an exemplary phenomenology as understood with the help of a characteristic fundamental literary canon.I argue that analytic philosophy is pursued within a canon that makes it difficult to raise hermeneutical questions about natural science, and that it assumes a generally positivistic phenomenology. I argue that hermeneutical phenomenology currently defines itself in dialectical opposition to “science” as understood by analytic philosophy, and has failed to exploit the opportunity of making its own positive contribution to the philosophy of science by examining for itself the phenomenology of laboratory work, especially data production, and the transformation of the language of theory into a descriptive language of scientific phenomena. A “strong” hermeneutical philosophy of natural science, then, challenges both analytic philosophy and the existing tradition of hermeneutical phenomenology. (shrink)

Two hundred years ago, Friedrich Schleiermacher took critical issue with Immanuel Kant's intellectual notion of intuition as applied to human nature (Wellmon 2006). He found it necessary to modify—"hermeneutically," as he said—Kant's notion of anthropology by enabling it to include as human the new and strange human tribes Captain Cook found in the Pacific South Seas. A similar hermeneutic move is necessary if physics is to include the local contextual empirical syntheses of relativity and quantum physics. In this hermeneutical revision (...) the synthesis is formed around the notion of a Hilbert Vector Space as the universal grammar of physics, adding to it the dynamic of the Schrödinger equation, and representing empirical "observables" by projection operators that map the subspaces of definite measurable values. Among the set of observable projection operators, some pairs share the same subspace, commute with one another, and share a common laboratory setting. Other pairs do not share this property and are described as being mutually complementary. Complementary symmetries introduce into the discursive language of physics the commonsense notion of contextuality. The new synthesis, proposed by Eugene Wigner, John von Neumann, and (in his own way) Paul Dirac, brought physics into the community of common language and established it as a work of general human achievement. 1.

A structural analogy is pointed out between a check hermeneutically developed phenomenological description, based on Husserl, of the process of perceptual cognition on the one hand and quantum mechanical measurement on the other hand. In Husserl's analytic phase of the cognition process, the 'intentionality-structure' of the subject/object union prior to predication of a local object is an entangled symmetry-making state, and this entanglement is broken in the synthetic phase when the particular local object is constituted under the influence of an (...) iota ('inner horizon') and the 'facticity' of the local world ('outer horizon'). Replacing 'perceptual cognition' by 'measurement' and 'subject' by 'expert subject using a measuring device' the analogy of a formal quantum structure is extended to the conscious structure of all empirical cognition. This is laid out in three theses: about perception, about classical measurement, and about quantum measurement. The results point to the need for research into the quantum structure of the physical embodiment of human cognition. (shrink)

Using the methods of hermeneutic phenomenology, and against the background of the principle that the real is what is or can be given in a public way in perception as a state of the World, and of the thesis established elsewhere that acts of perception are always epistemic, contextual, and hermeneutical, the writer proposes that objects of scientific observation are perceptual objects, states of the World described by theoretical scientific terms and, therefore, real. This thesis of Hermeneutical Realism is proved (...) by showing how the response of a standard instrument is 'read' as if it were a 'text'. Conclusions are then drawn about a number of topics, including Scientific Realism, Conventionalism, and Cultural Relativism. (shrink)

This essay is dominated by three themes that recur contrapuntally in Heisenberg’s writings: observation, description, and ontology—prompted always by a concern about the role played by the subjective inquirer in scientific meaning-making, and by the ontology of scientific claims. Among the related themes are; the tension between paradigmatic concerns with structure and philosophical concerns with reality, the possibility of scientific revolutions, such as relativity and quantum mechanics, that can overthrow the classical traditions of natural science and the inadequacy of a (...) psychophysical parallelism for an epistemology of reason. The influence of Husserl and Heidegger is in his neokantian concern about the role of subjectivity. Heisenberg was a long-time friend of Heidegger and familiar with Heidegger’s hermeneutical phenomenology and its critique of Greek philosophy; he also contributed an essay to a Festschrift in Heidegger’s honor in 1959.

The classical notion of scientific objectivity is a property of propositional truth. It is the property of being open to testing and inspection, in principle, by all men, although in practice perhaps, the testing of a scientific claim is restricted to the members of a community of professional experts. It is, moreover, the property of being stable in time, true eternally as it were; for objective truth is thought to express what is so independently of human interests, initiatives, bias, social (...) circumstances and historical environment. Often there is the added connotation that what is so is pictured not in its relationship to man, but absolutely, as it were, in itself, or in its relations to the rest of nature, where nature is taken to have an essence independently of the meaning conferred on nature by Dasein. All this is expressed as truth-invariance relative to synchronous communities of knowers whether sympatric or allopatric : truth-invariance relative to allochronous communities of knowers, and truth-invariance relative to the physical transformations and substitutions which define the objective content of a scientific law or theory.

Today when congressional committees are investigating laboratory notebooks, when the media debate the possibility of cold-fusion, and advertising presents drugs as remedies for everything from infertility to hair loss, the stage is set for the postmodern crisis of confidence in science. This crisis was ushered in by F. Nietzsche, and taken up by M. Heidegger, J. Habermas, Critical Theory, the Strong School of the Sociology of Science, by Margaret Thatcher, on the right and by Jacques Derrida, on the left—and, of (...) course, by the Greens. For so many intellectuals of the population, science has lost its legitimacy as uniquely privileged life-giving knowledge. The spirit of postmodernism in philosophy, as exemplified by Nietzsche, Heidegger, Derrida, Lyotard, and many who claim to be hermeneutic thinkers, has turned against the "master narratives" of our culture which give legitimacy to the institutions of our society and has turned especially against the privileged status of modernist science which is central to this narrative. Since modernism dominates our society mostly through the success and prestige of formal and theoretical systems of codification allied with technical expertise, the most pressing problem for postmodernity then is coming to terms with science and its prevalent modernist interpretation.
