Many philosophical theories of self-knowledge can be understood as attempts to explain why self-ascriptions enjoy a certain kind of authority that other-ascriptions lack (the Authority Thesis). The aim of this paper is not to expand the stock of existing explanations but to ask whether the Authority Thesis can be adequately specified. To this end, I identify three requirements that must be met by any satisfactory specification. I conclude that the search for an adequate specification of the Authority Thesis leads to (...) a dilemma: it either yields an interpretation under which the thesis is philosophically interesting but false, or it produces an interpretation under which the thesis is actually true but of minor philosophical interest.

Ranking theory delivers an account of iterated contraction; each ranking function induces a specific iterated contraction behavior. The paper shows how to reconstruct a ranking function from its iterated contraction behavior uniquely up to multiplicative constant and thus how to measure ranks on a ratio scale. Thereby, it also shows how to completely axiomatize that behavior. The complete set of laws of iterated contraction it specifies amend the laws hitherto discussed in the literature.

What is an image? An image, it might be said, is a kind of amity between the medium and the model it assumes. The purpose of this relationship is to reproduce the model and to become similar to it. Such a definition invites – perhaps in a purely playful way – some preliminary considerations.

The intervention of the divine in human history, more precisely the transition from fiction to incarnation that is peculiar to the origins of Christianity, marks a turning-point in our understanding of the genealogical principle. With a Son of Man who is also Son of God and his Mother's Father, there is no paternity and, more generally, no genealogy that is not reversible. To this questioning of elementary kinship structures we should add the contesting of the hitherto accepted distribution of genders (...) and sexes. The superimposition of the Holy Family and the Trinity created an uncertain sex whose effect is to uncouple sex from its functions, in particular procreation. Hence a circulation and instability of sex. It is from this viewpoint that we should see the notion of an androgynous Christ and the Church Fathers' thinking on the resurrected body. (shrink)

The respectably legitimate offspring of an age-old affair between writing and picture-making, the calligramme — that is, “a poem in which the typographical layout creates a picture, generally related to the ‘subject’ of the text” (Dictionnaire des littératures, Larousse) — is often seen as an esoteric minority art of dubious reputation. Starting from an exclusively Western approach to the history of the calligramme, my aim is to demonstrate that this artform may in fact represent something more than simply (here I (...) deliberately use a metaphor from the far east, as a counterargument to my theme) the “Kyogen of the No theatre” — i.e., more than a lightweight interlude between more literary, aesthetic, even metaphysical preoccupations — more elevated, more serious, or, in general terms, more extended. Apart from the play and the pleasure of an approach that is creative in terms of letters and language, it contains serious elements related to the actual exercise of writing in our media civilization.

We reconstruct “the classical transformational theory” of Chomsky, and fit it into the structuralist theory of science. We describe both the formal and the empirical features of this classical account, so that one basic hypothesis of this theory – where central notions are used – can be formulated, and in which Chomsky’s “classical” distinction between surface structure and deep structure is clarified. In the empirical claim of this theory are words, sentences and high-structured entities in an inseparable way intertwined. We (...) claim that the formal structure of a natural language is not approximately the same as that of an empirical theory in general. We clarify two special points which affect the structure of the notion of an empirical theory, namely: the delineation of intended applications and the fit between data and models. We hold that the concept of the empirical claim for a linguistic theory should be generalized in comparison with the “standard” structuralist approach. (shrink)

Wolfgang Welsch examines global aestheticization phenomena, probes the relationship of aesthetics and ethics, and considers the broad relevance of aesthetics for contemporary thinking. He argues that modes of thought familiar from the aesthetic realm comprise fundamental paradigms for understanding todayÆs reality. The implications for specific and everyday issues are demonstrated in studies of architecture, advertising, the Internet, and our perception of the life world. Surgically precise, innovative, and, above all, relevant, this book is an essential resource, providing the analysis (...) of contemporary culture with philosophical bite. Aesthetics is to transcend itself, address the whole realm of aethesis, and hence enable orientation in the contemporary condition. Undoing aesthetics means releasing it from old cultural binds and giving it new ties with the future. (shrink)

Furthermore we show that the contrapositive of the collection-schema gives rise to instances of the law of excluded middle and hence. (shrink)

This article discusses the history of the concepts of potential infinity and actual infinity in the context of Christian theology, mathematical thinking and metaphysical reasoning. It shows that the structure of Ancient Greek rationality could not go beyond the concept of potential infinity, which is highlighted in Aristotle's metaphysics. The limitations of the metaphysical mind of ancient Greece were overcome through Christian theology and its concept of the infinite God, as formulated in Gregory of Nyssa's theology. That is how the (...) concept of actual infinity emerged. However, Gregory of Nyssa's understanding of human rationality went still further. He said that access to the infinity of God was to be found only in an asymptotic ascension, as expressed in apophatic theology, and this view endangered the rationality of theology. Deeply influenced by the apophatic tradition, Nicholas of Cusa avoided this danger by showing that infinity could be accessed by symbolic representation and asymptotic mathematical reasoning. Thus, he made an immense contribution in making infinity rationally accessible. This endeavor was finally realized by Georg Cantor. This rational accessibility revealed discernible structures of infinity, such as the continuum hypothesis, and the cardinal numbers. However, the probable logical inconsistency of Georg Cantor's all-encompassing Absolute Infinity points to an intuitive understanding of infinity that goes beyond its rational structures – as in apophatic theology.

In this volume, renowned experts in psychoanalysis reflect on the relationship between psychoanalysis and religion, in particular presenting various controversial interpretations of the question if and to what extent monotheism semantically and structurally fits psychoanalytic insights. Some essays augment traditional religious critiques of Freudianism with later religio-philosophical theories on, for example, femininity. Others explore the relation between psychopathology and morality from the Freudian premise that psychopathology shows in an excessive way aspects or mechanisms of the human psyche that constitute our (...) subjectivity, moral capacities, and behavior.Contributors: Andreas De Block, KU Leuven-University of Leuven; Fethi Benslama, University of Paris Diderot; Sergio Benvenuto, ISTC, Rome; Gohar Homayounpour, Shahid Beheshti University, Tehran; Felix de Mendelssohn, Sigmund Freud University, Vienna; Julia Kristeva, University of Paris Diderot; Lode Lauwaert, KU Leuven-University of Leuven; Siamak Movahedi, University of Massachusetts; Wolfgang Muller-Funk, University of Vienna; Gilles Ribault, University of Paris Diderot; Céline Surprenant, University of Sussex; Inge Scholz-Strasser, Sigmund Freud Foundation; Herman Westerink, University of Vienna; Joel Whitebook, Columbia University; Moshe Zuckermann, Tel Aviv University.

In his seminal paper, ‘Can There Be Vague Objects?’ (1978), Gareth Evans advanced an argument purporting to prove that the idea of indeterminate identity is incoherent. Aware that his argument was incomplete as it stands, Evans added a remark at the end of his paper, in which he explained how the original argument needed to be modified to arrive at an explicit contradiction. This paper aims to develop a modified version of Evans’ original argument, which I argue is more promising (...) than the modification that Evans proposed in his remark. Last, a structurally similar argument against the idea of indeterminate existence is presented. (shrink)

All statements describing physical reality are derived through interpretation of measurement results that requires a theory of the measuring instruments used to make the measurements. The ultimate measuring instrument is our body which displays its measurement results in our mind. Since a physical theory of our mind-body is unknown, the correct interpretation of its measurement results is unknown. The success of the physical sciences has led to a tendency to treat assumption in physics as indisputable facts. This tendency hampers the (...) development of new theories capable of addressing the foundations of mind. To show the possibility that false interpretations of experimental results have lead to equally false projections onto physical reality may have happened, the double slit experiment and special relativity experiments are examined in detail. I will show that strongly held a-priory beliefs characterizing measurement instruments have lead to unjustified but widely held concepts in physical theories. For example the assumption that material bodies have minds can change the interpretation of experiments to produce alternative physical theories. Since some material bodies have minds this paper calls for a review of the conscious observer’s role in the execution and interpretation of fundamental physics experiments in order to verify or challenge the basic beliefs adopted in standard physical theories.

The aim of this paper is to confirm that it was Hamann's translation of Hume's "Treatise" (I.4.7) which triggered Kant's critical turn in 1768/69. If this is indeed so, then Kant's inaugural dissertation must be reassessed, in particular the doctrine, to be found there, that we have cognitive access to the intelligible world. This doctrine is part of a strategy for tackling the problem highlighted by Hume; that there may be conflicting principles at work in the human mind, i.e., an (...) antinomy. The dissertation's strategy failed and so raised the question of how categories can refer to objects. (shrink)

The paper attempts to rationalize cooperation in the one-shot prisoners' dilemma (PD). It starts by introducing (and preliminarily investigating) a new kind of equilibrium (differing from Aumann's correlated equilibria) according to which the players' actions may be correlated (sect. 2). In PD the Pareto-optimal among these equilibria is joint cooperation. Since these equilibria seem to contradict causal preconceptions, the paper continues with a standard analysis of the causal structure of decision situations (sect. 3). The analysis then raises to a reflexive (...) point of view according to which the agent integrates his own present and future decision situations into the causal picture of his situation (sect. 4). This reflexive structure is first applied to the toxin puzzle and then to Newcomb's problem, showing a way to rationalize drinking the toxin and taking only one box with-out assuming causal mystery (sect. 5). The latter result is finally extended to a rationalization of cooperation in PD (sect. 6). (shrink)

Modern theory of rationality has truly grown into a science of its own. Still, the general topic remained a genuinely philosophical one. This essay is concerned with giving a brief overview. Section 2 explains the fundamental scheme of all rationality assessments. With its help, a schematic order of the main questions concerning the theory of rationality can be given; the questions turn out to be quite unevenly addressed in the literature. Section 3 discusses the fundamental issue that the theory of (...) rationality seems to be both a normative and an empirical theory. Section 4, finally, shows how the unity of the theory of rationality can nevertheless be maintained. (shrink)

Dieser Essay behandelt das Phanomen der doppelten Belastung von Frauen, die zugleich "ihren" Haushalt in Ordnung halten und einem "normalen" Beruf nachgehen (wollen/miissen).Er konzentriert sich auf zwei Seiten einer dialektischen Situation: einmal das naheliegende Faktum, daB eine zweifache Belastung die Arbeitshetze intensiviert, den StreB intensiviert und die freie Zeit so weit "auffriBt", daB ein humanes Leben ausgeschlossen bleibt: die Not der Tugend; zum andern der weniger leicht zugangliche, gleichwohl reale Sachver halt, daB Belastungen auch Herausforderungen darstellen, Bewiih rungs proben mit (...) der Chance zu personlicher Entwicklung und strate gischer Entfaltung: die Tugend der Not. Beide Seiten gehOren untrennbar zusammen. Wie ihr Verhaltnis im einzel nen verlauft, ist eine offene Frage. Vermutlich folgt es jener "Laffer-Kur ve", die einige Zeit lang in der wirtschaftswissenschaftlichen Diskussion eine Rolle spielte: d.h., bis zu einem gewissen Maximum fordern zusatzli che Belastungen die Entfaltung der Personlichkeit; was dariiber hinausgeht, lost regressive Veranderungen aus. Den Umschlagpunkt galte es theoretisch zu bestimmen und praktisch zu stabilisieren. (shrink)

Collingridge’s dilemma is one of the most well-established paradigms presenting a challenge to Technology Assessment (TA). This paper aims to reconstruct the dilemma from an analytic perspective and explicates three assumptions underlying the dilemma: the temporal, knowledge and power/actor assumptions. In the light of the recent transformation of the science, technology and innovation system—in the age of technoscience —these underlying assumptions are called into question. The same result is obtained from a normative angle by Collingridge himself; he criticises the dilemma (...) and advances concepts on how to keep a technology controllable. This paper stresses the relevance of the dilemma and of Collingridge’s own ideas on how to deal with the dilemma. Today, a positive interpretation of technoscience for effective TA is possible.

Truth is a stable, epistemically unconstrained property of propositions, and the concept of truth admits of a non-reductive explanation: that, in a nutshell, is the view for which I argued in Conceptions of Truth. In this paper I try to explain that explanation in a more detailed and, hopefully, more perspicuous way than I did in Ch. 6.2 of the book and to defend its use of sentential quantification against some of the criticisms it has has come in for.
