Gegenstand vorliegender Arbeit ist das Problem des fehler haften Staatsakts. Dementsprechend besteht ihre eigentliche Auf gabe darin, jene Schwierigkeiten darzulegen und zu iiberwinden, welche eine Theorie des fehlerhaften Staatsakts bietet. Die Ge winnung grundsatzlicher Klarheit iiber Ziel und Weg schien dabei um so mehr gefordert, als die bisherigen Versuche einer wissen schaftlichen Behandlung des Gegenstandes zwar unbestreitbar wert volle Einzelausfiihrungen, keineswegs aber methodische Sicherheit gebracht haben. Insoweit dieser Mangel nach hier vertretener Ansicht an der Haltlosigkeit des angewandten formalistischen Ver fahrens (...) liegt, bilden nachfolgende Untersuchungen einen Beitrag zu einer teleologischen Methode der Rechtsauslegung iiberhaupt. Herr Dr. med. hon. c. Ferdinand Springer iibernahm hoch herzigerweise auch unter den gegenwartigen Verhaltnissen die Drucklegung meiner Arbeit.

This paper provides strong evidence challenging the self-interest assumption that dominates the behavioral sciences and much evolutionary thinking. The evidence indicates that many people have a tendency to voluntarily cooperate, if treated fairly, and to punish noncooperators. We call this behavioral propensity “strong reciprocity” and show empirically that it can lead to almost universal cooperation in circumstances in which purely self-interested behavior would cause a complete breakdown of cooperation. In addition, we show that people are willing to punish those who (...) behaved unfairly towards a third person or who defected in a Prisoner’s Dilemma game with a third person. This suggests that strong reciprocity is a powerful device for the enforcement of social norms involving, for example, food sharing or collective action. Strong reciprocity cannot be rationalized as an adaptive trait by the leading evolutionary theories of human cooperation (in other words, kin selection, reciprocal altruism, indirect reciprocity, and costly signaling theory). However, multilevel selection theories of cultural evolution are consistent with strong reciprocity. (shrink)

A unique synthesis of the contemporary, Anglo-American philosophical approach with an abiding concern for classical philosophical problems. This book seeks to clarify the precise structure of self-consciousness and self-determination and elucidates their significance for our philosophical understanding of self-knowledge and human agency.The analysis challenges traditional models of theoretical self-knowledge and practical self-relation and elaborates an account of rationally grounded responsibility that jointly fulfills the demands of autonomy and authenticity.Tugendhat's study is a unique synthesis of the contemporary Anglo-American philosophical approach with (...) an abiding concern for classical philosophical problems. It brings the methods of linguistic analysis to bear on such epistemological, moral, and metaphysical issues as the meaning and interconnections of self-knowledge, ego identity, rational self-understanding, and freedom of the will. In this context, the views of Wittgenstein, Heidegger, Mead, and Hegel are searchingly examined. The philosophical testimony of Kierkegaard, Freud, Habermas, and others is also presented and weighed. Self-Consciousness and Self-Determination is based on a series of lectures given at Heidelberg. The book is included in the series Studies in Contemporary German Social Thought, edited by Thomas McCarthy. (shrink)

“Here is the first Kant-biography in English since Paulsen’s and Cassirer’s only full-scale study of Kant’s philosophy. On a very deep level, all of Cassirer’s philosophy was based on Kant’s, and accordingly this book is Cassirer’s explicit coming to terms with his own historical origins. It sensitively integrates interesting facts about Kant’s life with an appreciation and critique of his works. Its value is enhanced by Stephen Körner’s Introduction, which places Cassirer’s Kant-interpretation in its historical and contemporary context.”—Lewis White Beck (...) “The first English translation (well done by James Haden) of a 60-year-old classic intellectual biography. Those readers who know Kant only through the first _Critique_ will find their understanding of that work deepened and illuminated by a long explication of the pre-critical writings, but perhaps the most distinctive contribution is Cassirer’s argument that the later _Critiques_, and especially the _Critique of Judgment_, must be understood not as merely applying the principles of the first to other areas but as subsuming the latter into a larger and more comprehensive framework.”—Frederick J. Crown, _The Key Reporter_ “_Kant’s Life and Thought_ is that rare achievement: a lucid and highly readable account of the life and work of one of the world’s profoundest thinkers. Now for the first time available in an admirable English translation, the book introduces the reader to two of the finest minds in the history of philosophy.”—Ashley Montagu. (shrink)

© 2016 South African Journal of Philosophy. This article explores current issues in South African philosophy curriculum design. Four questions are considered, each followed by a supplementary note. Firstly, the place of philosophy from other traditions, particularly Western philosophies, in South African curricula is considered. The related note reflects on whether different philosophical traditions in curricula should be treated separately or integrated. Secondly, ambiguity in some important authors reception of plural traditions is identified and investigated to see what we can (...) derive from their example for our philosophical practice. The related note looks at "decolonisation of the curriculum". Thirdly, I affirm the importance of relevance as a criterion for curriculum development, interrogating the meaning of this criterion for philosophy. The related note focuses on interpreting student feedback. Fourthly, the continued presence of "white" lecturers in South African philosophy departments is discussed against the background of the tension between the Mandela and Biko paradigms in contemporary society. The related note considers ideological resonances of our response to this issue in other parts of the world. Finally, the articles ideas are presented as an attempt to map argumentative options, clarify some of their merits and implications, and acknowledge their limits. (shrink)

A formulation of Full Lambek Calculus in the framework of natural deduction is given.

In archaic societies the oath is not an explanation given in particular form by an official order, but, at the very most, a selfcondemnation and therefore, together with trial by ordeal and duel, a means to ending serious conflicts. In the early Greek epos there is only one single paragraph that still testifies to such a regulation ; and less than 200 years later Xenophanes describes what happens when in the legal reality of more secular/enlightened societies the old piece of (...) evidence remains preserved.

The paper introduces a new type of rules into Natural Deduction, elimination rules by composition. Elimination rules by composition replace usual elimination rules in the style of disjunction elimination and give a more direct treatment of additive disjunction, multiplicative conjunction, existence quantifier and possibility modality. Elimination rules by composition have an enormous impact on proof-structures of deductions: they do not produce segments, deduction trees remain binary branching, there is no vacuous discharge, there is only few need of permutations. This new (...) type of rules fits especially to substructural issues, so it is shown for Lambek Calculus, i.e. intuitionistic non-commutative linear logic and to its extensions by structural rules like permutation, weakening and contraction. Natural deduction formulated with elimination rules by composition from a complexity perspective is superior to other calculi. (shrink)

The article presents a full proof‐theoretic semantics for natural deduction based on an extended inversion principle: the elimination rule for an operator q may invert the introduction rule for q, but also vice versa, the introduction rule for a connective q may invert the elimination rule for q. Such an inversion—extending Prawitz' concept of inversion—gives the following theorem: Inversion for two rules of operator q (intro rule, elim rule) exists iff a reduction of a maximum formula for q exists. The (...) inversion theorem is specified to two logics, Lambek calculus (LC) and intuitionistic linear logic (ILL), with four propositional connectives: two multiplicatives (implication and conjunction) and two additives (conjunction and disjunction), with two quantifiers and two modals. LC is defined by using elimination rules by composition. ILL is defined by using usual general elimination rules. Elimination rules by composition are an exciting alternative to general elimination rules; in some cases, they do not need permutations. (shrink)

The article aims to advance our understanding of what the early Heidegger had in mind when he spoke about technics. Taking GA 18, Grundbegriffe der aristotelischen Philosophie, as a guiding text, Heidegger's “destructive” reading of the two notions most directly associated with Aristotle's presentation of technics—τεχνη and εξις—will be examined, especially with reference to the portrayal of technics in the Nicomachean Ethics. It will be argued that Aristotle already exaggerated the distinction between virtue and skill and that, instead of insisting (...) on their similarities (as will be argued to be desirable), Heidegger drove the two notions even further apart. This enabled him to form a warped picture of technical life, which he exploited as a counter image to develop an unrealistically non-technical notion of πρα;ξις, which Heidegger implicitly advocates.
