The book presents a thoroughly elaborated logical theory of generalized truth-values understood as subsets of some established set of truth values. After elucidating the importance of the very notion of a truth value in logic and philosophy, we examine some possible ways of generalizing this notion. The useful four-valued logic of first-degree entailment by Nuel Belnap and the notion of a bilattice constitute the basis for further generalizations. By doing so we elaborate the idea of a multilattice, and most notably, (...) a trilattice of truth values – a specific algebraic structure with information ordering and two distinct logical orderings, one for truth and another for falsity. Each logical order not only induces its own logical vocabulary, but determines also its own entailment relation. We consider both semantic and syntactic ways of formalizing these relations and construct various logical calculi. (shrink)

The Sophists owe their place in the history of philosophy to Plato – but also their bad reputation. He uses them to profile his image of the philosopher against them. For him, sophistry is the ultimate in distance from philosophy while at the same time being close to philosophy; it is as related to this »as the wolf is to the dog«. I first trace the negative exaggeration of sophistry and the sophists in Plato, which is reflected in the ineradicable (...) negative connotation of »sophist« and »sophistic«. The great intellectual-historical importance of the Sophists does not lie primarily in what they independently contributed to philosophy, but in the establishment of a conception of rhetoric as we encounter it in Isocrates, which became the most important educational institution in antiquity alongside and before philosophy.

Translation of Kleist’s Short Story On the Marionette Theatre.

Graham Priest takes the relation of identity to be non-transitive. In this paper, we are going to discuss several consequences of identity as a non-transitive relation. We will consider the Henkin-style completeness proof for classical first-order logic with a non-transitive “identity” predicate, Leibniz-identity in Priest’s second-order minimal logic of paradox, and the question whether or not identity of individuals should be defined as Leibniz-identity.

This chapter is concerned with logical aspects of negation, i.e. with the role of negation in valid inferences and hence with the contribution negation makes to the truth and falsity conditions of declarative expressions. Negation is an important philosophical and logical concept. Often differences between logical systems can ‐ at least partially ‐ be described as differences between the notions of negation used in these logics.

Nuestro punto de partida es la concepción de Merleau-Ponty del lenguaje como "habla". Sostenemos que esta, como experiencia corporal del lenguaje -como lenguaje "en" nosotros-, permite comprender el fenómeno de la /nter-culturalidad como un fenómeno esencialmente /ntra-cultural, en el sentido de una experiencia de la cultura "desde dentro", es decir, desde la experiencia que cada quien hace del lenguaje. Este carácter endógeno e individual de pensar la cultura pone en evidencia, sin embargo, un "entre-lazamiento" recíproco originario entre lo propio y (...) lo extraño que impide de entrada privilegiar ya sea una visión universalista o totalizante o bien individualista o regionalista de la cultura. En dos momentos doy cuenta de este planteamiento: 1. Mundo de la vida y diversidad cultural y 2. El habla como lugar de acceso a las culturas. Our starting point is the conception in Merleau Ponty of language as "speech". We support this concept as corporal experience of language -as language "in" us - allows to understand the phenomenon of ¿nter-culturality as an essentially ¿ntra-cultural phenomenon, in the sense of an experience of culture "from within", that is to say; from the experience that everyone does with the language. This endogenous and individual character of thinking about culture highlights, however, a reciprocal "entanglement" originated among one's own and the strange that initially prevents to privilege, even a universal or totalizing or either an individualistic or regionalist vision of culture. Two moments I take on this approach: 1. World of life and cultural diversity. 2. Speech as an access place to the cultures. (shrink)
