This dissertation is about human knowledge of reality. In particular, it argues that scientific knowledge is bounded by historically available instruments and theories; nevertheless, the use of several independent instruments and theories can provide access to the persistent potentialities of reality. The replicability of scientific observations and experiments allows us to obtain explorable evidence of robust entities and properties. The dissertation includes seven chapters. It also studies three cases – namely, Higgs bosons and hypothetical Ϝ-particles (section 2.4), the Ptolemaic and (...) Kepler model of the planets (section 6.7), and the special theory of relativity (chapter 7). -/- Chapter 1 is the introduction of the dissertation. Chapter 2 clarifies the notion of the real on the basis of two concepts: persistence and resistance. These concepts enable me to explain my ontological belief in the real potentialities of human-independent things and the implications of this view for the perceptual and epistemological levels of discussion. On the basis of the concept of “overlapping perspectives”, chapter 3 argues that entity realism and perspectivism are complementary. That is, an entity that manifests itself through several experimental/observational methods is something real, but our knowledge of its nature is perspectival. Critically studying the recent views of entity realism, chapter 4 extends the discussion of entity realism and provides a criterion for the reality of property tokens. Chapter 5, in contrast, develops the perspectival aspects of my view on the basis of the phenomenological-hermeneutical approaches to the philosophy of science. This chapter also elaborates my view of empirical evidence, as briefly expressed in sections 2.5 and 4.5. Chapter 6 concerns diachronic theoretical perspectives. It first explains my view of progress, according to which current perspectives are broader than past ones. Second, it argues that the successful explanations and predictions of abandoned theories can be accounted for from our currently acceptable perspectives. The case study of Ptolemaic astronomy supports the argument of this chapter. Chapter 7 serves as the conclusion of the dissertation by applying the central themes of the previous chapters to the case study of special relativity theory. I interpret frame-dependent properties, such as length and time duration, and the constancy of the speed of light according to realist perspectivism. (shrink)

In this study I argue that Husserl’s phenomenology is compatible with a realistic interpretation of scientific theories. That said, I distinguish between the realistic interpretation of scientific theories and scientific realism. The former holds that the theoretical terms of a scientific theory are intended to refer, and that if we have good reason to believe that a scientific theory is true then we also have good reason to believe the entities it refers to exist. Scientific realism holds that the world (...) as described by the physical sciences not only exists, it is the only world that exists—the world of everyday perceptual experience must be demoted to the status of a mere appearance. My case for the compatibility of Husserl’s phenomenology with a realistic interpretation of scientific theories is based on a distinction between scientific laws and scientific theories. I hold that Husserl’s instrumentalism, if one can call it that, is restricted to an interpretation of scientific laws; accordingly, his anti-realism is directed against the reification of ideal objects constructed in the course of the exact mathematical representation of scientific laws, not against the theoretical entities postulated in the explanation of those laws. At the end of the study I seek to allay the fear that if one adopts a realistic interpretation of scientific theories one is thereby committed to some version of scientific realism. (shrink)

REVIEW (1): "Jeff Kochan’s book offers both an original reading of Martin Heidegger’s early writings on science and a powerful defense of the sociology of scientific knowledge (SSK) research program. Science as Social Existence weaves together a compelling argument for the thesis that SSK and Heidegger’s existential phenomenology should be thought of as mutually supporting research programs." (Julian Kiverstein, in Isis) ---- REVIEW (2): "I cannot in the space of this review do justice to the richness and range of Kochan's (...) discussion [...]. There is a great deal in this foundational portion of Kochan's discussion that I find tremendously interesting and engaging [...]." (David R. Cerbone, in Studies in History and Philosophy of Science) ---- REVIEW (3): "Science as Social Existence will be of interest not only to Heidegger scholars but to anyone engaged in science and technology studies. [...] This is an informative and original book. Kochan should be praised for his clear, pleasant-to-read prose." (Michael Butler, in CHOICE). (shrink)

This paper develops a phenomenological defense of Ian Hacking's experimental realism about unobservable entities in physical science, employing historically undervalued resources from the phenomenological tradition in order to clarify the warrant for our ontological commitments in science. Building upon the work of Husserl, Merleau-Ponty and Heelan, the paper provides a phenomenological correction of the positivistic conception of perceptual evidence maintained by antirealists such as van Fraassen, the experimental relevance of which is illustrated through a phenomenological interpretation of the 1974 discovery (...) of the J/ ψ particle generally regarded as evidence for the charmed quark. The argument then turns to address known problems in Hacking's account, demonstrating that his own instrumentalist criterion of the real is inadequately rooted in the phenomenology of perception, and as a result, passes over the true ontological significance of experimental phenomena. The paper maintains that the proper criterion, only indirectly related to instrumentality, is the distinctive style of the real encountered in perception: empirical pregnancy. With this notion and Merleau-Ponty's associated reversibility thesis, I show that the phenomenological tradition provides insights into the warrant for our realist commitments that have yet to be adequately acknowledged by philosophers of science.

This paper draws on the phenomenological-hermeneutical approaches to philosophy of science to develop realist perspectivism, an integration of experimental realism and perspectivism. Specifically, the paper employs the distinction between “manifestation” and “phenomenon” and it advances the view that the evidence of a real entity is “explorable” in order to argue that instrumentally-mediated robust evidence indicates real entities. Furthermore, it underpins the phenomenological notion of the horizonal nature of scientific observation with perspectivism, so accounting for scientific pluralism even in the cases (...) of inconsistent models. Overall, realist perspectivism is proposed as the way to go for (phenomenologically-hermeneutically minded) philosophers of science. (shrink)

This article critically reviews an outstanding collection of new essays addressing Edmund Husserl’s Crisis of European Sciences. In Science and the Life-World (Stanford, 2010), David Hyder and Hans-Jörg Rheinberger bring together an impressive range of first-rate philosophers and historians. The collection explicates key concepts in Husserl’s often obscure work, compares Husserl’s phenomenology of science to the parallel tradition of historical epistemology, and provocatively challenges Husserl’s views on science. The explications are uniformly clear and helpful, the comparative work intriguing, and the (...) criticisms interesting but uneven. The article also elaborates on Husserl’s phenomenological method as it relates to the historiography of science, and compares his views on mathematical idealisation to more recent work in the analytical tradition.

Abstract Not much scholarly work is needed in order to stumble across many passages where Edmund Husserl seems to advocate an anti-realist attitude towards the natural sciences. This tendency, however, is not well-received within the secondary literature. While some commentators criticize Husserl for his alleged scientific anti-realism, others argue that Husserl's position is much more realist than the first impression indicates. It is against this background that I want to argue for the following theses: a) The basic outlook of Husserl's (...) epistemology as well as his more substantial comments regarding the natural sciences indeed result in a (sophisticated version of) scientific anti-realism which bears certain resemblances to Bas van Fraassen's constructive empiricism; b) This scientific anti-realism can be defended against the two most common objections raised in the secondary literature; c) It is only by means of this sophisticated version of scientific anti-realism that phenomenology can circumvent the problem of ?scientific objectivism?

Husserl claimed that all theoretical scientific concepts originate in and are valid in reference to 'life-world' experience and that scientific traditions preserve the sense and validity of such concepts through unitary and cumulative change. Each of these claims will, in turn, be sympathetically laid out and assessed in comparison with more standard characterizations of scientific method and conceptual change as well as the history of physics, concerning particularly the challenge they may pose for scientific realism. The Husserlian phenomenological framework is (...) accepted here without defense, and hence the present project is limited to the task of asking what can and cannot be accommodated within that framework on its own terms.

O presente artigo se propõe a confrontar uma leitura antirrealista da obra do fenomenólogo Edmund Husserl e a sugerir que ela pode ser interpretada mais adequadamente como marco do realismo científico. Para tanto, primeiramente, será exposto um dos mais recentes e elaborados projetos nos quais Husserl se relaciona ao Empirismo Construtivo de Van Fraassen. Posteriormente, serão assinaladas as dificuldades encontradas para interpretar algumas teses de Husserl desde o marco antirrealista, enfocando, principalmente, a discussão sobre os inobserváveis, mostrando como a sua (...) existência não é uma tese indiferente à fenomenologia husserliana. Por fim, será indicado como Husserl poderia estar mais próximo do marco realista. In this paper I confront an anti-realistic approach to Edmund Husserl's Phenomenological work and I suggest that this work could most suitably constitute into the Scientific Realistic framework. In order to this, I will first show one of most recent and elaborate claims which relates Husserl with Van Fraassen's Constructive Empiricism. Later, I will point out some existing difficulties to interpret the Husserlian thesis using the anti-realist framework. I will specially focus on the discussion about unobservable entities, arguing how the existence of the unobservable is not an alien thesis to the Phenomenology of Husserl. Finally, I will point out how Husserl is closer to the Realistic framework. (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)
