On the whole our study has made a plea for the combined research into the history, methodology and philosophy of science. There is an intricate communication between these aspects of science, philosophy being both a fruit of scientific developments and a higher-level frame of reference for discussion on the inevicable metaphysical issues in science.As such philosophy can be very useful to science, but should never impose its ideas on the conduct of scientists . ... Zie: Summary.

This paper examines a historical case of conceptual change in mathematics that was fundamental to its progress. I argue that in this particular case, the change was conditioned primarily by social processes, and these are reflected in the intellectual development of the discipline. Reorganization of mathematicians and the formation of a new mathematical community were the causes of changes in intellectual content, rather than being mere effects. The paper focuses on the French Revolution, which gave rise to revolutionary developments in (...) mathematics. I examine how changes in the political constellation affected mathematicians both individually and collectively, and how a new professional community—with different views on the objects, problems, aims, and values of the discipline—arose. On the basis of this account, I will discuss such Kuhnian themes as the role of the professional community and normal versus revolutionary development.Author Keywords: Carnot; Monge; Kuhn; Revolution; Conceptual change.

In this paper I explore possibilities of bringing post-positivist philosophies of empirical science to bear on the dynamics of mathematical development. This is done by way of a convergent accommodation of a mathematical version of Lakatos's methodology of research programmes, and a version of Kuhn's account of scientific change that is made applicable to mathematics by cleansing it of all references to the psychology of perception. The resulting view is argued in the light of two case histories of radical conceptual (...) innovations. (shrink)

Recent philosophical accounts of mathematics increasingly focus on the quasi-Empirical rather than the formal aspects of the field, The praxis of how mathematics is done rather than the idealized logical structure and foundations of the theory. The ultimate test of any philosophy of mathematics, However idealized, Is its ability to account adequately for the factual development of the subject in real time. As a text case, The works and views of felix klein (1849-1925) were studied. Major advances in mathematics turn (...) out to be most adequately understood as shifts to new conceptualizations at different levels of idealization and abstraction. The implications of the model are explored with special reference to modern philosophical views of the nature and the warrants of mathematical claims to knowledge, And the methodology of the development of this knowledge.

It is shown how the historiographic purport of Lakatosian methodology of mathematics is structured on the theme of analysis and synthesis. This theme is explored and extended to the revolutionary phase around 1800. On the basis of this historical investigation it is argued that major innovations, crucial to the appraisal of mathematical progress, defy reconstruction as irreducibly rational processes and should instead essentially be understood as processes of social-cognitive interaction. A model of conceptual change is developed whose essential ingredients are (...) the variability of rational responses to new intellectual and practical challenges arising in the cultural environment of mathematics, and the shifting selective pressure of society. The resulting view of mathematical development is compared with Kuhn's theory of scientific paradigms in the light of some personal communications. (shrink)

In the first part of this article I investigated the Popperian roots of Lakatos's Proofs and Refutations, which was an attempt to apply, and thereby to test, Popper's theory of knowledge in a field—mathematics—to which it had not primarily been intended to apply. While Popper's theory of knowledge stood up gloriously to this test, the new application gave rise to new insights into the heuristic of mathematical development, which necessitated further clarification and improvement of some Popperian methodological maxims. In the (...) present part I analyze this second phase in the development of Lakatos's Popperian programme in mathematics, and its connection to the methodology of scientific research programmes.

Lakatos's Proofs and Refutations is usually understood as an attempt to apply Popper's methodology of science to mathematics. This view has been challenged because despite appearances the methodology expounded in it deviates considerably from what would have been a straightforward application of Popperian maxims. I take a closer look at the Popperian roots of Lakatos's philosophy of mathematics, considered not as an application but as an extension of Popper's critical programme, and focus especially on the core ideas of this programme (...) as they appeared where Popper specifically addressed philosophical problems concerning mathematics.

A philosophically comprehended account is given of the genesis and evolution of the concept of protein. Characteristic of this development were not shifts in theory in response to new experimental data, but shifts in the range of questions that the available experimental resources were fit to cope with effectively. Apart from explanatory success with regard to its own range of questions, various other selecting factors acted on a conceptual variant, some stemming from a competing set of research questions, others from (...) an altogether different field of inquiry, and still others from the external environment. These results are best explained on, hence support, an evolutionary model of the progress of experimental investigation, whose outlines are briefly discussed. (shrink)

This collection presents the English-language reader for the first time with essays that are representative of Bernstein's much-neglected revisionist period, 1901-1921. Bernstein himself suggested that this later work included significant new elements, indicating further progress in his liberal-socialist theory. Bernstein's later work acquires additional significance in light of the events of 1989, which have discredited not only Marxism-Leninism, but revolutionary Marxist theory in general, thus making the reevaluation of Bernstein's revisionism a worthwhile experience.

Der Himmel als Stimmungsbogen des Denkens über Tartu im Februar 1808.

"Allerdings, das ist eine grosse Frage, der ich zu sehr ausgewichen bin, die Evidenz des Ich als ein Identisches, das also doch nicht in dem Bündel bestehen kann." (Husserl, 1907) Bekanntlich verwirft Husserl in den Logischen Untersuchungen die Auffassung, "dass die Beziehung auf das Ich etwas zum we sentlichen Bestande des intentionalen Erlebnisses selbst Gehöriges sei'',! und bildet um 1907, nach Einführung der phänomenolo gischen Reduktion, "die Beziehung auf das Ich zu unterlassen, oder von ihr zu abstrahieren" geradezu die Bedingung, (...) ein "reines Phänomen im Sinne der Phänomenologie" 2 zu gewinnen. Und bekanntlich heisst es demgegenüber in den Ideen von 1913: "Unter den allgemeinen Wesenseigentümlichkeiten des tran szendental gereinigten Erlebnisgebietes gebührt eigentlich die erste Stelle der Beziehung auf das,reine' Ich",3 und revidiert Husserl in der zweiten Auflage der Logischen Untersuchungen von 4 1913 seine Stellungnahme zur Frage des reinen Ich. Weniger bekannt ist bisher, wie Husserl auf seinem Denkweg von der einen zur anderen Stellungnahme zum Problem des Ich gekommen ist. Was bewegte ihn, das "Ich" in die phänomeno logische Problematik einzubeziehen? Zu vermuten war, dem Wandel in der Stellung zum Problem des Ich liege ein Wandel im Verständnis der Phänomenologie selbst zugrunde. Welche Phänomene motivierten, auf dem phänomenologischen Boden selbst, die Einbeziehung des Ich? Vor allem dieser Frage gehen wir, unter Berücksichtigung des Nachlassmaterials des Husserl Archivs (Leuven), in unserer Studie nach. (shrink)

"Like Hanslick, Professor Payzant is both musician and philosopher; and he has brought the knowledge and insights of both disciplines to this large undertaking." --Gordon Epperson, _Journal of Aesthetics and Art Criticism_.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 12.1 (2005) 49-54 [Access article in PDF] In Search for Normativity of Unconscious Reasoning Gerrit Glas Keywords emotion, practical reason, reasoning, normativity, unconscious, appropriation Puzzles Church Is "deeply" puzzled by "the idea that we can be ignorant of our own rea-sons" (2005, 31). I was, at first sight, puzzled by this puzzlement.There is no question that we, indeed, are ignorant of many of our (...) reasons. In cases of routine behavior, for instance, we are often not, or only dimly, aware of the reasons for doing something. When I use the indicator when taking a turn to the left with my car, I have no conscious reason for doing so. It has become routine behavior, acquired during my lessons in car driving. My non-awareness may even be considered as sign of my excellence as a driver. This non-awareness is most noteworthy in all those cases in which we, again routinely, withdraw from a particular action. Education and training not only teach us how and why to perform certain activities, they also give us reasons to refrain from all sorts of other actions. There are many reasons to do certain things; there seem to be many more reasons for not doing other things. To suppose that having reasons would by necessity involve conscious awareness of these reasons would life make impossible to live.So, ignorance seems to be very common, not to say trivial. This raises the question whether there is anything nontrivial in the attempt to make sense of ignorance of our reasons. What element or aspect of ignorance is it that may evoke philosophical interest? Jennifer Church seems to have in mind different overlapping concerns. In the first part of her paper, she addressesthe issue of legitimacy; that is, the specification of conditions under which attributions of unconscious content are legitimate or illegitimate; andthe issue of normativity; that is, the question how and why unconscious reasons can be normative for me.The first question can be discussed without reference to a self; the second question cannot. In the second part of the paper there arise new concerns:the issue of having reasons that can not be recognized as reasons by oneself, "strange reasons" so to say, with spatial reasoning as a paradigm case; andthe issue of being moved by ones reasons through the visceral connection between desires and beliefs on the one hand and motor activity (external or internal) on the other hand; this connection is secured by our emotions.[End Page 49] Recapitulation Let me try to recapitulate some of the main issues. Church makes, first, a distinction between having access to one's reasons and recognizing one's reasons as reasons. She proceeds by discussing the no-access problem in terms of a functionalist metaphysics of mental states. Then she suggests that ascribing unconscious content (or reason) to a person, in fact, boils down to the evaluation of the appropriateness of the ascription of a specimen of practical reasoning to the subject. Practical reasoning involves the structured connection and interaction between beliefs and desires. This structure can be studied at the level of animal psychology; however, there are some important differences between humans and animals: humans can withhold assent, they can lie, and they may recognize mistakes, whereas animals cannot. The possibility of being mistaken about one's reasons leads from the issue of legitimacy to the issue of normativity. For a reason to become my reason, the belief–desire network should make sense, I should feel normatively compelled in some way. So the issue of normativity cannot be studied apart from the possibility of recognition. To recognize a reason as one's reason, one has—at some level of understanding—to assent with its content, even if this occurs implicitly.In the second part the conditions for recognition are investigated in the form of an analysis of unconscious reasons that are strange. Strange reasons are not recognized because they function in some different way compared to normal conscious reasoning. Strangeness is defined here in terms of a different way of... (shrink)

Creativity — A New Vocabulary proposes a novel approach to the way in which we talk and think about creativity. It covers a variety of topics not commonly associated with creativity that offer us valuable insights and open up new and exciting possibilities for creative action. This collection of essays challenges the 'traditional' vocabulary of creativity and its preference for individuals, brains, cognition, personality, divergent thinking, insight, and problem solving. Instead, the book proposes a more dynamic and relational perspective that (...) considers creativity as an embodied, social, material, and cultural process. This book will be useful for a wide range of specialists within the humanities and social sciences, as well as practitioners from applied fields who are looking for novel ways of thinking about and doing creative work.
