It is an area of enquiry which has been suppressed, in recent years, by the development of historical methodologies which eschew all epistemological deliberations and their established ramifications. This thesis, therefore, addresses itself to the following areas. In Chapter One consideration is given to the degree to which the present ascendancy of contextual, social history of science depends upon formulating methodological strategies that deny the very legitimacy of a progress history of scientific ideas. These strategies are shown to depend upon the old definition of internalist, intellectual history of science, which drew upon related areas in the philosophy of science. Some basic arguments ^ in favour of the possibility of progressive histories of scientific ideas, which have been ignored by the discipline as a whole, are rehearsed. Chapter Two is devoted to an account of how a present-day philosophy of science, aim-oriented empiricism, offers a solution to the problem of induction which, by demonstrating that scientific rationality has a historical dimension, provides a suitable historiographic framework for a progress-oriented history of scientific ideas. Chapter Three examines the work of Galileo in the light of this new historiographic framework. Firstly, it is demonstrated to be an option 7 for exegesis, an account of how ideally rational science ought to be which does not rationally ' reconstruct the past Secondly, it illuminates Galileo’s work in significantly new ways, demonstrating that by making explicit the metaphysical dimension already implicit in Galileo’s methodology, his work can be shown to have an underlying unity - and be part of a progressive tradition - in ways which other interpretations, distracted by the seeming disunity at the methodological level, fail to appreciate. Finally, Chapter Four considers the possibility of a beneficial, reciprocal relationship between developments in the philosophy of science and in progressive histories of scientific ideas. 3 CONTENTS pages CHAPTER ONE * CRITIQUE OF CERTAIN TRENDS IN THE HISTORY OF SCIENCE 7-94 Social History of Science and the Concept of Scientific Progress 7 Hunt the Historiography 11 Influences on the Development of a Social History of Science 15 What are the Advantages of Constructivism? 34 Methodological Relativism 37 Anthropological and Sociological Techniques 39 Whig Historiography and Ideas of Progress 45 Problems Associated With Social History and Historiography of Science 53 What is Whiggish About Whig History? 60 A Possible Route Towards A Solution 69 Generalized Arguments Concerning the Pursuit of the Subject Matter 82 References for Chapter One 90 CHAPTER TWO* AIM-ORIENTED EMPIRICISM: A SUITABLE METHODOLOGICAL FRAMEWORK TO PROVIDE CRITERIA FOR THE EXECUTION OF A PROGRESSIVE HISTORY OF SCIENTIFIC IDEAS 95-162 Expounding Aim-Oriented Empiricism 98 A Brief Summary of Aim-Oriented Empiricism 99 Some Problems and Some Solutions 107 The Operation of Aim-Oriented Empiricist Science 112 Going Beyond Popper 115 4 The Illuminative Strengths of Aim-Oriented Empiricism 117 The Principles of Uniformity 121 Solution to the Problems of Induction 127 The Methodological Problem of Induction 127 The Justificational Problem Gf Induction 130 Aim-Oriented Empiricism and the History of Science 133 Progress History of Science is Possible 133 Towards a Historiography of Science 135 Aim-Oriented Empiricism and Whig historiography 150 Aim-Oriented Empiricism and Present-Day History of Science 152 References for Chapter Two 162 CHAPTER THREE* GALILEO AND THE AIM-ORIENTED EMPIRICIST PERSPECTIVE 163-267 Introduction 163 Level 5: The Comprehensibility Theses 167 The Articulation of the Level 4 Blueprint 177 The Development of the Level 3 Blueprint 184 The Blueprint Progression 189 Blueprint Clashes 194 A Brief Resume 198 Methodology Implies Blueprint Even in Unexpected Cases 224 The Father of Modern Science? 228 Essence, Measurement, or Something Else? 238 Matter in Motion 250 Unity at the Metaphysical Level 254 References for Chapter Three 262 CHAPTER FOUR* THE BEST OF BOTH WORLDS? 268-278 References for Chapter Four 278 5 APPENDIX 279-285 Diagram 1 285 BIBLIOGRAPHY 286 6 CHAPTER ONE CRITIQUE OF CERTAIN TRENDS IN THE HISTORY OF SCIENCE Social History of Science and the Concept of Scientific Progress This thesis is concerned with that branch of the history of science which takes the central problem to be scientific progress, defined as the growth of knowledge and understanding about the world. The question which started me thinking about these issues, paradoxically, involves the scarcity of present-day contributions to this area. Why does no- one, or at least hardly anyone, consider the progress of scientific knowledge any more? It is not so very many years since such a notion seemed an obvious and reasonably unproblematic form of exposition for the history of science. Indeed there is an interesting disciplinary point to be made here: more than a few historians - and I mean here historians whose subject areas lie outside the realm of science, such as historians of art and architecture, ancient civilizations, politics, warfare, society, and economics - still do regard the history of science as a special case.1 They tend to hold that because of its peculiar and heavily intellectual, or ideas-oriented, subject matter, it is not altogether susceptible to the same methodological and historiographical pronouncements that non-scientific history is. However, a great many contemporary historians of science would disagree with this because their discipline is increasingly, sometimes it seems overwhelmingly, studied in terms of social considerations which eschew all epistemological deliberations and their established ramifications. Anyone talking or writing about such entities as knowledge and progress (and for that matter, rationality, objectivity, and verisimilitude) is liable to be told that such entities cannot do any analytical work in the history of science. They are peremptory definitions, they are banal, 1 This was brought home to me during a conversation with Professor Arthur Marwick at an Open University history symposium held in Cambridge in 1996. 7 they cannot help the aspiring historian of science to get any kind of a purchase on the past. The question that therefore needs to be asked, is ‘is this sort of position entirely unproblematic and are the kinds of criticisms that it levels at the older forms of exposition sustainable?’. Examinations of explanations of scientific progress and change have occasionally surfaced in recent years. In a book entitledScrutinizing Science, edited by Donovan and the Laudans, a methodological approach is taken to a range of philosophical theories of scientific change. This is done in the expressed hope that a rigorous comparison with relevant historical evidence might produce a survivor among the competing theses that would give an empirically‘ well-grounded picture of the workings of science ’ and (by implication) provide a historiographical framework too.[1] Although well aware that attempts to bring together histories and theories would raise considerable conceptual and methodological problems, the editors decline to address these problems in any depth.f2] In their summing-up eleven of the original thirty-eight theses survive, rather than the hoped-for one. All eleven are somewhat modified and in fact most of them have only survived the testing in a highly qualified form. David Gooding, who is sympathetic to many of the aims of the editors, calledit ‘a worthy start which everyone interested in the philosophical import o f historical studies should read with care. ’[5] I think the emphasis has to be very much on the word ‘start’. Paul Hoch, who is less sympathetic, regardsScrutinizing Science as being like, a new philosophical meta-methodology of rational scientific appraisal which, it is maintained, has been shown to be applicable to all (or nearly all) ‘cases’ - but which rarely if ever brings in the relevant social processes in the relevant research communities and their relations to broader

  • Imagination: a Philosophical Examination of The
    1 The ‘Reality Oriented’ Imagination: a Philosophical Examination of the Imagination in ‘Mentalization’ and ‘Neuropsychoanalysis’. Annie Hardy Thesis submitted for the degree of Doctor of Philosophy University College London 2017 2 I, Annie Hardy, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. 3 Abstract This thesis is concerned with the conceptualization of the imagination in contemporary psychoanalytic theory, focusing in particular on its connection with knowledge. I will propose that imaginative processes form the core of psychic ‘health’ by instantiating a state of mind in which the subject is genuinely open to ‘learning from experience’. At the centre of the investigation is a psychic process that I term the ‘reality oriented’ imagination: a form of conscious mental activity that facilitates an epistemological connection with both the internal and external worlds and renders the unobservable psychological experiences of others accessible. The concept of the ’reality oriented’ imagination significantly disrupts Freud’s portrayal of the imaginative processes as a form of wish-fulfilment in which the individual’s attention is drawn away from external reality and placed under the sway of the pleasure principle. Such differing presentations of the imagination across psychoanalytic models can arguably be understood by considering several major shifts in psychoanalytic theorizing since Freud’s time. I will propose that these changes can be characterised as an ‘epistemic turn’: a general movement in psychoanalysis towards framing the internal world as strategic rather than compensatory, and a corresponding understanding of psychopathological processes as a response to failures in understanding and prediction rather than instinctual conflict.

  • Logic Vs Illogic: Why Mathematics Is Easy and Life Is Hard
    Logic vs illogic: why mathematics is easy and life is hard Eugenia Cheng University of Cambridge 1st March, 2004 Approximate text of a talk given to the Trinity Mathematical Society, Cambridge, on 1st March 2004 and to the University of Chicago Mathematics Club on 14th February 2005. Abstract Generations of even well-educated adults are under the delusion that mathematics is difficult, and that mathematicians must therefore be very clever. In this talk I will explode this myth and show that mathematics is in fact easy, and moreover that mathematics is precisely “that which is easy” for an appropriate sense of ‘easy’. We will take ‘easy’ to mean ‘attainable by logical thought processes’. As a corollary, or a converse, or a contrapositive or something, we will discuss the importance of illogical thought processes in non-mathematical life and the fact that life is thus difficult. Hence or otherwise we will deduce that mathematics is not life, nor can it nor should it be. 1 Introduction It is a fact universally acknowledged that mathematics is difficult. If you tell someone you’re a mathematician you invariably get one of two answers. Either “Oh, I never could understand maths” or “Wow, you must be really clever.” Of course, since mathematics is difficult it does follow that we mathematicians must all be very clever. As a mathematician, I am quite tempted to believe this. But is it true? What I’m going to do today is take the bold step – perhaps rash step – of exploding the Myth of Mathematics. A bit like the Masked Magician whose TV show explained how magic tricks work – with the result that he was vilified by the Magical community.

  • Naturalized Epistemology, Or What the Strong Programme Can't Explain
    Studies in History and Philosophy of Science Stud. Hist. Phil. Sci. 36 (2005) 135–148 www.elsevier.com/locate/shpsa Naturalized epistemology, or what the Strong Programme canÕt explain Karyn L. Freedman University of Guelph, Guelph, Ont., Canada, N1G 2W1 Received 26 September 2003; received in revised form 5 April 2004 Abstract In this paper I argue that the Strong ProgrammeÕs aim to provide robust explanations of belief acquisition is limited by its commitment to the symmetry principle. For Bloor and Barnes, the symmetry principle is intended to drive home the fact that epistemic norms are socially constituted. My argument here is that even if our epistemic standards are fully natu- ralized—even relativized—they nevertheless can play a pivotal role in why individuals adopt the beliefs that they do. Indeed, sometimes the fact that a belief is locally endorsed as rational is the only reason why an individual holds it. In this way, norms of rationality have a powerful and unique role in belief formation. But if this is true then the symmetry principleÕs emphasis on Ôsameness of typeÕ is misguided. It has the undesirable effect of not just naturalizing our cognitive commitments, but trivializing them. Indeed, if the notion of ÔsimilarityÕ is to have any content, then we are not going to classify as Ôthe sameÕ beliefs that are formed in accor- dance with deeply entrenched epistemic norms as ones formed without reflection on these norms, or ones formed in spite of these norms. My suggestion here is that we give up the sym- metry principle in favor of a more sophisticated principle, one that allows for a taxonomy of causes rich enough to allow us to delineate the unique impact epistemic norms have on those individuals who subscribe to them.

I start from the longstanding criticism that pragmatism unduly neglects the past in favor of the future. As a response, I interpret Peirce‘s pragmatism and its associated doctrines in light of his accounts of memory, history, and testimony. In particular, I follow Peirce‘s own example of a deep engagement with the history of philosophy and related fields. For example, Peirce‘s account of memory is linked to the development of a notion of the unconscious, which brings in both his work as an experimental psychologist and his interaction with figures such as Helmholtz, Wundt and James.

  • Navigating Recalcitrant Emotions
    Navigating Recalcitrant Emotions Alex Grzankowski Journal of Philosophy Recalcitrant emotions conflict with our considered judgments. Faced with the rollercoaster deemed entirely safe, one might fear it nevertheless. After a vivid dream, someone might feel angry with her partner and yet judge that her partner did nothing wrong.1 Such pairs create a normative conflict—one should not both be afraid and judge that there is nothing dangerous, one should not be angry with one’s partner while judging that the partner did nothing wrong. Such pairs are structurally inconsistent in the sense that they exert a kind of rational pressure on one another that is relieved when one of the attitudes is revised.2 However, capturing this inconsistency has proven very difficult, and the various failures to capture it have guided much of the recent theorizing about the emotions. Cognitivism, for all its virtues, is believed to have been completely undermined by recalcitrant emotions, and the Perceptual theories that looked to take its place met with trouble not long after. Much of the nuance and in-fighting one finds in more recent Neo-Cognitivist theorizing revolves around making sense of the normativity of the emotions, and one gets the sense that the theorist who can account for cases of recalcitrance will have taken an important theoretical lead. The present essay offers a new approach to recalcitrant emotions, an approach that can be accepted by a great many theorists. It is correct that some views fall prey to the challenges posed by recalcitrant emotions (and we will diagnose why that is), but one interesting upshot of the view to be offered is that it provides a simple way of accounting for the phenomena that has room for wide adoption.

  • The Arationality of Perception: Comments on Susanna Siegel*
    Final version March 2018. Forthcoming in PPR symposium The Arationality of Perception: Comments on Susanna Siegel* ADAM PAUTZ Brown University Susanna Siegel’s The Rationality of Perception flies in the face of orthodoxy, proposing a revolution in our understanding of perceptual justification. It is both creative and rigorous. She first defends what she calls the Downgrade Thesis about perceptual justification. Then she suggests a bold explanation of Downgrade: experiences themselves can be rational or irrational. I will pursue a question about her foundational Downgrade Thesis. In closing, I will briefly address her bold proposed explanation of it. 1. A Question about the Downgrade Thesis The Downgrade Thesis (DT) concerns cognitive penetration, which Siegel calls “hijacking”. To avoid controversies about whether it actually occurs, let’s focus on a hypothetical case, the hijacked hallucination. Suppose you have an irrational expectation that there will be a red and round tomato on the table in the next room. You enter the room, and you magically have a perfect hallucination as of a red and round tomato on the table, in response to your prior expectation (see Figure 1 below). Suppose you also magically forget about your prior expectation. So you have no idea this is a hallucination originating from your expectation – in general, no idea anything is amiss. Do you have the ordinary level of justification for believing that a red and round thing is there? DT says No (14, 67). In this case, even though you have a vivid experience as of a red and round thing right there and you have no idea that your experience is nonveridical, you have less than the ordinary, base-line (propositional) justification for believing that a red and round thing is on the table, the level of justification you would get from a non- hijacked tomato-experience.

  • Patterns of Knowledge Communities in the Social Sciences
    Patterns of Knowledge Communities in the Social Sciences ROBERTPAHRE ~STRACT THESTUDY OF SCIENCE AND SCIENTIFIC COMMUNITIES is dominated by philosophies and sociologists. These disciplines naturalIy take different approaches to the subject, the one epistemological and the other sociological. While recogniz- ing the role of society in shaping science, this article emphasizes the way that the epistemology of science influences scientific society. The epistemologi- cal status of various scientific discourses also shapes scientific communities. Discourses about methods have different effects on communities than dis- courses about theories; positivist discourses and nonpositivist discourses also shape communities differently. The best way to think about science and scientific communities is a dialogue between two hybrid approaches-i.e., a social epistemology and an epistemological sociology. Each presents some challenges to information science. INTRODUCTION Knowledge is found in communities built by individuals. Our efforts to systematize, categorize, or reorganize that knowledge must consider not only the individual knower but also the knowledge communities. In other words, studying knowledge presents a sociological problem in addition to an intel- lectual or philosophical one.’ For this reason, most contemporary studies of science treat science purely as a sociological issue. In contrast to this literature, it will be argued here that knowledge communities present not just a sociological problem. The substance of science, and what is labeled here as the “epistemology” of science,2affects the pattern by which scientific knowledge is organized. In particular, the epistemological status of a scientific discourse shapes the sociological struc- Robert Pahre, School of Public Policy, 408 Lorch Hall, 611Tappan Street, The University of Michigan, Ann Arbor, MI 48109 LIBRARYTRENDS, Vol.

  • Critical Philosophy of Halakha (Jewish Law): the Justification of Halakhic Norms And
    Critical Philosophy of Halakha (Jewish Law): The Justification of Halakhic Norms and Authority Yonatan Yisrael Brafman Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2014 © 2014 Yonatan Yisrael Brafman All rights reserved ABSTRACT Critical Philosophy of Halakha (Jewish Law): The Justification of Halakhic Norms and Authority Yonatan Brafman Contemporary conflicts over such issues as abortion, same-sex marriage, circumcision, and veiling highlight the need for renewed reflection on the justification of religious norms and authority. While abstract investigation of these questions is necessary, inquiry into them is not foreign to religious traditions. Philosophical engagement with these traditions of inquiry is both intellectually and practically advantageous. This does not demand, however, that these discussions be conducted within a discourse wholly internal to a particular religious tradition; dialogue between a religious tradition and philosophical reflection can be created that is mutually beneficial. To that end, this dissertation explores a central issue in philosophy of halakha (Jewish law): the relation between the justification of halakhic norms and halakhic-legal practice. A central component of philosophy of halakha is the project of ta’amei ha-mitzvot (the reasons for the commandments). Through such inquiry, Jewish thinkers attempt to demonstrate the rationality of Jewish religious practice by offering reasons for halakhic norms. At its best, it not only seeks to justify halakhic norms but also elicits sustained reflection on issues in moral philosophy, including justification and normativity. Still, there is a tendency among its practitioners to attempt to separate this project from halakhic-legal practice.
