This book has grown out of eight years of close collaboration among its authors. From the very beginning we decided that its content should come out as the result of a truly common effort. That is, we did not "distribute" parts of the text planned to each one of us. On the contrary, we made a point that each single paragraph be the product of a common reflection. Genuine team-work is not as usual in philosophy as it is in other (...) academic disciplines. We think, however, that this is more due to the idiosyncrasy of philosophers than to the nature of their subject. Close collaboration with positive results is as rewarding as anything can be, but it may also prove to be quite difficult to implement. In our case, part of the difficulties came from purely geographic separation. This caused unsuspected delays in coordinating the work. But more than this, as time passed, the accumulation of particular results and ideas outran our ability to fit them into an organic unity. Different styles of exposition, different ways of formalization, different levels of complexity were simultaneously present in a voluminous manuscript that had become completely unmanageable. In particular, a portion of the text had been conceived in the language of category theory and employed ideas of a rather abstract nature, while another part was expounded in the more conventional set-theoretic style, stressing intui tivity and concreteness.

Kant's theory of cognition centrally builds on his conception of self‐consciousness and the transcendental use of the phrase “I think”: the ability to add the phrase “I think” to a representation is a necessary condition of the ability to cognize objects. The paper argues that “I think”, rather than denoting the content of a predicative judgement, is typically an expression of the subject's thinking. It expresses a kind of self‐consciousness that, without assertively representing the subject itself, indicates that representational contents (...) are unified in a single consciousness of a single subject. Our aim is thus to develop and defend an expressivist interpretation of Kant's “I think”. (shrink)

It is often assumed that Aristotle, Boethius, Chrysippus, and other ancient logicians advocated a connexive conception of implication according to which no proposition entails, or is entailed by, its own negation. Thus Aristotle claimed that the proposition ‘if B is not great, B itself is great […] is impossible’. Similarly, Boethius maintained that two implications of the type ‘If p then r’ and ‘If p then not-r’ are incompatible. Furthermore, Chrysippus proclaimed a conditional to be ‘sound when the contradictory of (...) its consequent is incompatible with its antecedent’, a view which, in the opinion of S. McCall, entails the aforementioned theses of Aristotle and Boethius. Now a critical examination of the historical sources shows that the ancient logicians most likely meant their theses as applicable only to ‘normal’ conditionals with antecedents which are not self-contradictory. The corresponding restrictions of Aristotle’s and Boethius’ theses to such self-consistent antecedents, however, turn out to be theorems of ordinary modal logic and thus don’t give rise to any non-classical system of genuinely connexive logic,.

_ Source: _Page Count 16 This paper deals with an apparent tension in Wittgenstein’s _Philosophical Investigations_: Wittgenstein holds an expressivist position with regard to avowals, but also claims that the _doxastic_ avowal “I believe that p” is a “hesitant assertion” of p. It is argued that the tension is apparent only and that Wittgenstein’s expressivism in fact justifies and explains his views on “I believe”: avowals typically are _explicit expressives_ and usually implicate the corresponding illocutionary acts. The hesitant assertion of (...) p is the result of an implicature of the explicit expressive “I believe that p”. The paper also addresses the ambiguity of avowals and the possibility of thereby undermining the Frege–Geach objection to psychological expressivism. (shrink)

In addition to discussing some philosophical accounts of common sense, this article considers several ways in which common sense can be altered or disturbed in psychopathology. Common sense can be defined as practical understanding, capacity to see and take things in their right light, sound judgment, or ordinary mental capacity. The philosopher Vico described it as the ability to distinguish the probable from the improbable. Goethe understood common sense as an "organ" that is formed in communication for the purpose of (...) communication. Common sense is rooted in the intersubjective constitution of the life-world. Obsessive-compulsive patients show relatively mild disturbances of common sense. Patients with major affective psychoses, in their premorbid personality structure, are overly attached to common sense. In schizophrenia, however, there seems to be a true abdication of common sense involving a loss of "natural self-evidence." Even in premorbid states, such persons often lose both the sense of tact and the ability to "take things in their right light." Although logic, and the ability to engage in theoretical discussion, may be preserved, there is a loss of interpretive skills and the "faculty of judgment"; this results in an inability to cope with everyday practical and social activity. There is also a characteristic sense of perplexity, a sense of amazement before that which would normally seem self-evident and a frequent tendency to reflect upon the conditions of possibility of existence that otherwise remain concealed. The author suggests that the fragility of common sense should not be seen as a mere deficiency state. Rather, it derives from a basic vulnerability inherent in the very structure of being human.

We present a reconstruction of so-called classical, formal or Mendelian genetics using a notation which we believe is more legible than that of earlier accounts, and lends itself easily to computer implementation, for instance in PROLOG. By drawing from, and emending, earlier work of Balzer and Dawe (1986,1997), the present account presents the three most important lines of development of classical genetics: the so-called Mendel's laws, linkage genetics and gene mapping, in the form of a theory-net. This shows that the (...) set theoretic representation format used in the structuralist approach to the philosophy of science also applies to the domain of genetic theories. There construction is intended to lend more clarity to theme thodological, philosophical and didactical discussions of the foundations of genetics, and on the other hand to defend a formally, logically minded view of theories which seems to have become contested through the work of Feyerabend, Kuhn and Kitcher.

It has recently been argued that some cases of naked statistical evidence license a high credence, but not an outright belief. If this is correct, there cannot be an unconditional bridge principle from credence to outright belief. We show that at least one prominent putative counterexample to such a bridge principle is based on a mistake, by demonstrating that the statistical evidence falls short not only of licensing rational belief, but also of justifying a high credence.

Prominent instances of anti-luck epistemology, in particular sensitivity and safety accounts of knowledge, introduce a modal condition on the pertinent belief in terms of closeness or similarity of possible worlds. Very roughly speaking, a belief must continue to be true in close possibilities in order to qualify as knowledge. Such closeness-accounts derive much support from their (alleged) ability to eliminate standard instances of epistemic luck as they appear in prominent Gettier-type examples. The article argues that there are new Gettier-type examples (...) which are grounded in “distant” epistemic luck. It is demonstrated that sensitivity and safety theories cannot handle such examples.

One of the main controversies of the Logic Schools of the 12th century centered on the question: What follows from the impossible? In this paper arguments for two diametrically opposed positions are examined. The author of the ‘Avranches Text’ who probably belonged to the school of the Parvipontani defended the view that from an impossible proposition everything follows (‘Ex impossibili quodlibet’). In particular he developed a proof to show that by means of so-called ‘disjunctive syllogism’ any arbitrary proposition B can (...) be logically derived from a pair of contradictory propositions A and Not-A. The author of the Ars Meliduna instead argued that nothing follows from an impossible proposition (‘ex falso nihil sequitur’). This view is supported by various counterexamples which aimed to show that the admission of impossible premises would give rise to inconsistent conclusions. Upon closer analysis these inconsistencies do not, however, have the formal structure of a real contradiction like A and Not-A, but rather the structure of two rivalling conditionals like ‘If B then A’ and ‘If B then Not-A’. Hence these counterexamples rather have to be considered as refutations of the basic principles of ‘connexive logic’. (shrink)

The paper critically examines an objection to epistemic contextualism recently developed by Elke Brendel and Peter Baumann, according to which it is impossible for the contextualist to know consistently that his theory is true. I first present an outline of contextualism and its reaction to scepticism. Then the necessary and sufficient conditions for the knowability problem to arise are explored. Finally, it will be argued that contextualism does not fulfil these minimal conditions. It will be shown that the contrary view (...) is based on a misunderstanding of what contextualists are claiming. (shrink)

This book is a critical examination of Michel Foucault's relation to ancient Greek thought, in particular his famous analysis of Greek history of sexuality. Wolfgang Detel offers a new understanding of Foucault's theories of power and knowledge based on modern analytical theories of science and concepts of power. He offers a fresh and complex reading of the texts which Foucault discusses, covering topics such as Aristotle's ethics and theory of sex, Hippocratic diatetics, the earliest treatises on economics, and Plato's (...) theory of love. The result is a philosophically rich and probing critique of Foucault's later writings, and a persuasive account of the relation between ethics, power and knowledge in classical antiquity. His book will have a wide appeal to readers interested in Foucault and in Greek thought and culture. (shrink)

The systems Kα of transfinite cumulative types up to α are extended to systems K∞α that include a natural infinitary inference rule, the so-called limit rule. For countable α a semantic completeness theorem for K∞α is proved by the method of reduction trees, and it is shown that every model of K∞α is equivalent to a cumulative hierarchy of sets. This is used to show that several axiomatic first-order set theories can be interpreted in K∞α, for suitable α.

Hermann Grassmann is known to be the founder of modern vector and tensor calculus. Having as a theologian no formal education in mathematics at a university he got his basic ideas for this mathematical innovation at least to some extent from listening to Schleiermacher’s lectures on Dialectics and, together with his brother Robert, reading its publication in 1839. The paper shows how the idea of unity and various levels of reality first formulated in Schleiermacher’s talks about religion in 1799 were (...) transformed by him into a philosophical system in his dialectics and then were picked up by Grassmann and operationalized in his philosophical-mathematical treatise on the extension theory in 1844.

ZUSAMMENFASSUNGEs werden aus der Theologiegeschichte vier Typen von Willensfreiheit erhoben: der Typus liberum arbitrium , der Typus des nominalistischen Willensbegriffs , der Typus des mystischen Willensbegriffs und der Typus der Rechtfertigungslehre. Die ersten drei Typen werden psychologisch interpretiert im Sinne der Ichentwicklung als präautonom, autonom und transautonom. Nach der Darstellung und Diskussion der gegenwärtigen neurowissenschaftlichen Debatte um die Willensfreiheit wird ein systemisch verstandener Personbegriff als Brückenkonzept vorgeschlagen.SUMMARYFour types of free will are identified from the history of theology: The type of (...) the liberum arbitrium, the type of nominalism, the type of mysticism and the type of justification. For the first three types a psychological interpretation in terms of pre-autonomy, autonomy, and trans-autonomy is offered, based on self-transcendence as a religious feature. Two basically opposing interpretations of the same empirical data favoring free will and favoring a non-free will are discussed and compared with the theological tradition. A new notion of the person, based on the system theory, is suggested as a bridging concept to link the theological and neuro-scientific ideas of free will. (shrink)

The subject of this paper is a characterization of the $\Sigma_1$ -definable set functions of Kripke-Platek set theory with infinity and a uniform version of axiom of choice: $KP\omega+(uniform\;AC)$ . This class of functions is shown to coincide with the collection of set functionals of type 1 primitive recursive in a given choice functional and $x\mapsto\omega$ . This goal is achieved by a Gödel Dialectica-style functional interpretation of $KP\omega+(uniform\;AC)$ and a computability proof for the involved functionals.

Mit der vorliegenden Arbeit verfolgen wir drei Ziele. Erstens exemplifizieren wir einige wissenschaftstheoretische Fragen und die zugehörigen Antworten am sehr einfachen Beispiel der klassischen Stoßmechanik. Zweitens läßt sich an diesem Beispiel besonders klar der Begriff des Meßmodells darstellen; insbesondere erhalten wir eine vollständige Übersicht über alle Meßmodelle. Und drittens erhalten wir ein schönes Beispiel für den Begriff der Reduktion einer Theorie auf eine andere, denn die Stoßmechanik läßt sich auf einfache Weise auf eine Spezialisierung der Klassischen Partikelmechanik reduzieren.

We investigate certain statements about factors of unary functions which have connections with weak forms of the axiom of choice. We discuss more extensively the fine structure of Howard and Rubin's Form 314 from [4]. Some of our set-theoretic results have also interesting recursive versions.

In his contribution to this special issue, Almaas is keen to distinguish the individual streams of consciousness from 'pure awareness'. Since the existence of the former is presumably quite uncontroversial in present-day philosophy, I wish to concentrate on the latter, in particular on Almaas's claim that pure awareness is non-individual and ultimately it is 'the true owner of all experiences of all streams'. In my contribution, I wish to make plausible, by a philosophical reflection on the puzzling nature of the (...) I, that the ultimate subject of experience is indeed not the individual but 'the pure ego of the universe'. (shrink)

This handbook presents the state of the art of quantitative methods and models to understand and assess the science and technology system. Focusing on various aspects of the development and application of indicators derived from data on scholarly publications, patents and electronic communications, the individual chapters, written by leading experts, discuss theoretical and methodological issues, illustrate applications, highlight their policy context and relevance, and point to future research directions. A substantial portion of the book is dedicated to detailed descriptions and (...) analyses of data sources, presenting both traditional and advanced approaches. It addresses the main bibliographic metrics and indexes, such as the journal impact factor and the h-index, as well as altmetric and webometric indicators and science mapping techniques on different levels of aggregation and in the context of their value for the assessment of research performance as well as their impact on research policy and society. It also presents and critically discusses various national research evaluation systems. Complementing the sections reflecting on the science system, the technology section includes multiple chapters that explain different aspects of patent statistics, patent classification and database search methods to retrieve patent-related information. In addition, it examines the relevance of trademarks and standards as additional technological indicators. The Springer Handbook of Science and Technology Indicators is an invaluable resource for practitioners, scientists and policy makers wanting a systematic and thorough analysis of the potential and limitations of the various approaches to assess research and research performance.

In German archival terminology, the term Akte (file) as the basic unit of storage corresponds with its actualization as discursive (re-)action: the word ‘acts’ can designate at once the content of what is to be archived and the archive itself (Derrida, 1995: 17). Whereas the network of Prussian state archives from post-Napoleonic Germany until the First World War figured as a non-discursive juridical Read Only Memory of internal autopoetic bureaucracy, the German Weimar Republic sought to develop a more democratically transparent (...) archival information politics. This remained, however, for the most part an aspiration of the new political culture, and it was never systematically adopted by state institutions. By contrast, the National Socialist regime was the first to make use of archival memory in a partisan, active manner; Akten were actively instrumentalized as part of the programme for the annihilation of European Jewry. This article, based on the German state archives and also on a case-study concerning the ideologization of the Nietzsche Archive in Weimar, examines archival micro-politics as the site of discursive repression and production, between the affirmation and the resistance of discretely segmented memory to holistic ideological demands.

Our studies of aesthetics and knowledge have long tended to privilege the visual - at the expense, Wolfgang Ernst argues, of the aural. 'Sonic Time Machines' aims to correct that, presenting a striking new approach to theorising sound that investigates its split existence: as a temporal effect in a techno-cultural context and as a source of knowledge and information. Ernst creates a new term for the concept at the heart of the book, "sonicity," a flexible and powerful term that (...) allows him to consider sound with all its many physical, philosophical, and cultural valences."--Page 4 de la couverture.

This paper argues that social representations cannot be used as independent variables in causal explanations of social behaviour. It is shown that the structure of investigations often follows a causally explanatory design despite explicit statements to the contrary by the researchers. This fact is analyzed with three investigations. It is argued that verbal data used to assess the contents of a representation as independent variable are logically equivalent to data obtained from the “dependent” overt behaviour. Therefore these two kinds of (...) data must be seen as two illustrations of the same representational contents. The researchers’preference for using verbal data to assess the independent variable and the tendency to introduce a causal relationship between representation and behaviour is shown to result from misplacing folk-beliefs. Folk-beliefs about intentional causality, it is shown, pertain to the same level as other beliefs about the world on the part of the subjects. Hence they are part of the folk-representation itself and must be treated as such; their use in scientific accounts of the belief-action relationship is not implied by data on rational belief systems. It is suggested to conceptualize social representations as integral units of beliefs and action which may be used to explain causally subsequent contingent social events. The function of folk-beliefs in intentional causality for the self-concept of rational people and for social accountability is discussed. (shrink)

Der Beitrag erörtert Schopenhauers Theorie der Seinsgründe, nicht-kausaler ontologischer Gründe im Reich der Mathematik. Er weist nach, dass Schopenhauers entscheidendes Argument für Seinsgr??nde auf einer zu engen Konzeption von Erkenntnisgr??nden beruht. Wo Schopenhauer Seinsgr??nde sieht, liegen lediglich Begr??ndungen für Überzeugungen vor.

Using an event-study framework, we examine the stock market reaction to the announcement of firm withdrawal from countries designated as “State Sponsors of Terrorism” by the U.S. Department of State. We find that such announcements are, on average, linked to a statistically significant increase in firm value—an effect which already kicks in a few days before the announcement date. The observed abnormal returns are positively associated with the U.S. domicile, the intensity of a firm’s hitherto existing engagement in a designated (...) country, the number of countries that it withdraws from, as well as with a withdrawal from Iran compared to a withdrawal from other countries. Evidence suggests an increase in demand for stocks of withdrawing firms as a plausible cause of the positive stock price reaction. Pension and endowment funds are significantly less likely to own strategic stakes in firms with intensive involvements in countries designated as “State Sponsors of Terrorism.” We find some statistical evidence that firms remaining active in such countries have abnormally positive returns in the long run.
