We revisit the notion of initial sets by Xu and Cayrol 2016), i. e., non-empty minimal admissible sets in abstract argumentation frameworks. Initial sets are a simple concept for analysing conflicts in an abstract argumentation framework and to explain why certain arguments can be accepted. We contribute with new insights on the structure of initial sets and devise a simple non-deterministic construction principle for any admissible set, based on iterative selection of initial sets of the original framework and its induced (...) reducts. In particular, we characterise many existing admissibility-based semantics via this construction principle, thus providing a constructive explanation on the structure of extensions. We also investigate certain problems related to initial sets with respect to their computational complexity. (shrink)

Born a slave, but later earning his freedom and founding a school for teaching Stoicism to the sons of Roman noblemen, Epictetus has been a popular source of Stoic philosophy for centuries. Originally published in 1894 by the German scholar Adolf Bonhoeffer and here translated into English for the first time, this work remains the most systematic and detailed study of Epictetus' ethics. The basis, content, and acquisition of virtue are methodically described, while important related points in Stoic ethics (...) are discussed in an extensive appendix. Epictetus is compared throughout with the other late Stoics, Cicero, the early Stoics, and Christian moral thought. This approach shows that Stoic ethics continues to have great practical and pedagogical value. (shrink)

"Der vorliegende Band geht auf logikbezogene Spurensuche und vereinigt durchdachte, hochintelligente und zahlreiche neue Einsichten versprechende Texte. Wer sich ernsthaft mit Musik beschäftigt, sollte sich diesen Band nicht entgehen lassen." (bs, Musica sacra 4/2015) Texte zur Praxis, Theorie und Ästhetik der Musik beanspruchen den Begriff ›musikalische Logik‹, wobei die Vorstellungen über Geltung, Inhalt und Umfang dieses Begriffes weit divergieren. Im vorliegenden Buch wird eine problemgeschichtliche Klärung unternommen. Musikalische Logik erweist sich als Inbegriff der Bedingungen, unter welchen Musik als in sich (...) selbst begründeter Prozess erscheinen kann. Sie besteht in einem musikalischen Denken, dessen Zusammenhang generiert wird durch Differenzierung von Klangrelationen und Zeitmaßen, durch Bildung von Verknüpfungsweisen und Verlaufsformen, durch den variativen Gebrauch der resultierenden Modelle sowie durch Aufhebung und Neubildung der Konstituenten; als produktives Denken lässt sich das musikalische Denken die Wege nicht festlegen, die sich für seine Ausdrucks- und Kommunikationsweise bewährt haben. Musikalische Logik kann sich in voraushörbarer Konsequenz zeigen, aber auch und besonders in der Art, wie sich ein nicht zu antizipierender Prozess als in sich begründet erweist. Die Vielfalt der Möglichkeiten spricht nicht gegen die Erwartung von Logik in der Musik, sondern erfüllt die Eigenart des Logischen im Bereich des Schaffens gegenüber dem Logischen im Bereich des Erkennens. Die historische Darstellung führt von der Spätantike bis in die Mitte des 20. Jahrhunderts. Texts on the practice, theory and aesthetics of music make use of the term ‘musical logic’, although conceptions of the application, content and scope of the term differ greatly. This book attempts to solve this historical problem. Musical logic proves to be the embodiment of the conditions under which music can appear as a process founded in itself. It consists of musical thinking with ist context generated by the differentiation of relationships between sounds and of tempi, by the creation of forms of connection and progression, by the variational use of the resulting models and the suspension and re-creation of the constituent parts; as a form of productive thinking, music cannot define proven means for ist own expression and communication. Musical logic can manifest itself in consequences that can be aurally predicted, but also, and especially, in the ways in which a process that cannot be anticipated proves to be founded in itself. The range of possibilities does not contradict the expectation of logic in music but conforms to the peculiarity of logic in the sphere of creation as opposed to logic in the sphere of cognition. The historical presentation ranges from late antiquity to the mid 20th century. (shrink)

This paper offers a refutation of P. Duhem's thesis that the falsifiability of an isolated empirical hypothesis H as an explanans is unavoidably inconclusive. Its central contentions are the following: 1. No general features of the logic of falsifiability can assure, for every isolated empirical hypothesis H and independently of the domain to which it pertains, that H can always be preserved as an explanans of any empirical findings O whatever by some modification of the auxiliary assumptions A in conjunction (...) with which H functions as an explanans. For Duhem cannot guarantee on any general logical grounds the deducibility of O from an explanans constituted by the conjunction of H and some revised non-trivial version R of A: the existence of the required set R of collateral assumptions must be demonstrated for each particular case. 2. The categorical form of the Duhemian thesis is not only a non-sequitur but actually false. This is shown by adducing the testing of physical geometry as a counterexample to Duhem in the form of a rebuttal to A. Einstein's geometrical articulation of Duhem's thesis. 3. The possibility of a quasi a priori choice of a physical geometry in the sense of Duhem must be clearly distinguished from the feasibility of a conventional adoption of such a geometry in the sense of H. Poincare. And the legitimacy of the latter cannot be invoked to save the Duhemian thesis from refutation by the foregoing considerations. (shrink)

In this paper we ask whether approximation for abstract argumentation is useful in practice, and in particular whether reasoning with grounded semantics – which has polynomial runtime – is already an approximation approach sufficient for several practical purposes. While it is clear from theoretical results that reasoning with grounded semantics is different from, for example, skeptical reasoning with preferred semantics, we investigate how significant this difference is in actual argumentation frameworks. As it turns out, in many graphs models, reasoning with (...) grounded semantics actually approximates reasoning with other semantics almost perfectly. An algorithm for grounded reasoning is thus a conceptually simple approximation algorithm that not only does not need a learning phase – like recent approaches – but also approximates well – in practice – several decision problems associated to other semantics.

According to some cosmologists, the big bang cosmogony and even the (now largely defunct) steady-state theory pose a scientifically insoluble problem of matter-energy creation. But I argue that the genuine problem of the origin of matter-energy or of the universe has been fallaciously transmuted into the pseudo-problem of creation by an external cause. A fortiori, it emerges that the initial "true" and "false" vacuum states of quantum cosmology do not vindicate biblical divine creation ex nihilo at all.

The last decade has witnessed the beginnings of a remarkable convergence of Husserlian phenonenology and analytic philosophy of language, and the present volumes provide original and important texts of the phenomenological philosophy of language. Powerfully influenced by the writings of the early Husserl, Reinach fashioned Husserl’s ideas into a rigorous analytical methodology of his own, which he applied in particular to problems in logic and the theory of knowledge, and to the philosophies of law and psychology. The central role of (...) the concept of state of affairs in Reinach’s philosophy will bring to mind immediately the formal ontology of Wittgenstein’s Tractatus. Reinach’s most significant contribution, however, is contained in his The a priori foundations of civil law (1913), above all in the detailed analysis of the a priori structure of the act of promising. This amounts to an elaborate phenomenological theory of speech acts which anticipates, and in some respects goes beyond, the later theories of Austin and Searle. The present edition is in two volumes. Volume 1, which includes a biographical and thematic introduction by the editors, contains critical editions of those pieces published by Reinach himself. Volume II is a collection of all those items in Reinach’s surviving Nachlass which are in publishable form, including a number of important pieces not hitherto obtainable on such themes as ethical predicates, speech acts (“soziale Akte”), perception and the theory of number, together with a comprehensive sketch of the problems in the theory of knowledge, logic and ethics. Appended to this is a text-critical apparatus which also contains extensive discussions of the origins and sources of the materials in question. (shrink)

One does not have to be a specialist in religious history or the science of symbols in order to yield to the fascinating variations on the meanings of the Holy Grail. This strange vessel was undoubtedly already imbued with secret traditions when from the end of the 12th century to the end of the 13th century it was briefly resplendent with all the glory conferred by legend, before disappearing into the semi-darkness of mystery until Wagner's Parsifal brought it back to (...) light by drawing from it the redemption of the suffering inflicted by Schopenhauer's world.
