Katalog der griechischen Handschriften der Bayerischen Staatsbibliothek München, Bd. 10,1. [Catalogus codicum manu scriptorum Bibliothecae Monacensium historia] Wiesbaden, Harrassowitz 2002. 176 S. Seit über 10 Jahren arbeitet die Verf. an der Neubeschreibung der griechischen Handschriften der Staatsbibliothek in München; das vorliegende Werk behandelt die Provenienz der Signaturengruppe Monac.gr. 1–323, die vor dem Jahr 1803 in die bayrische Metropole kamen. Die Analyse der Geschichte von Bibliotheken bzw. einzelner Manuskripte zeigt den Einfluß politischer Fährnisse im 17. Jh. Da der Herzog von (...) Bayern 1623 zum Kurfürst erhoben wird, muß auch sein Exlibris geändert werden. Dieses neue Exlibris wird jedoch über das alte Eignerzeichen geklebt, so daß beide Formen erhalten blieben. Nach dem Sieg der Truppen der katholischen Mächte bei Nördlingen 1634 kamen Handschriften aus Tübingen nach München, deren Herkunft nach Konstantinopel führt: Dort wurden sie von Stephan Gerlach für Herzog Ludwig von Württemberg erworben.

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 paper presents predicate logical extensions of some subintuitionistic logics. Subintuitionistic logics result if conditions of the accessibility relation in Kripke models for intuitionistic logic are dropped. The accessibility relation which interprets implication in models for the propositional base subintuitionistic logic considered here is neither persistent on atoms, nor reflexive, nor transitive. Strongly complete predicate logical extensions are modeled with a second accessibility relation, which is a partial order, for the interpretation of the universal quantifier.

Thema dieses Buches – des letzten, das Cassirer vor seinem Tode im Manuskript zum Abschluß bringen konnte – ist der Versuch, die Wiederkehr des politischen Totalitarismus, dem er selbst nur durch die Emigration ins Exil entkam, philosophisch zu begreifen, d. h. aus den Ursachen herzuleiten.
