The abstract structure of inquiry - the process of acquiring and changing beliefs about the world - is the focus of this book which takes the position that the "pragmatic" rather than the "linguistic" approach better solves the philosophical problems about the nature of mental representation, and better accounts for the phenomena of thought and speech. It discusses propositions and propositional attitudes (the cluster of activities that constitute inquiry) in general and takes up the way beliefs change in response to (...) potential new information, suggesting that conditional propositions should be understood as projections of epistemic policies onto the world.Robert C.

This book, one of the first full-length studies of the modalities to emerge from the debate to which Saul Kripke, David Lewis, Ruth Marcus, and others are contributing, is an exploration and defense of the notion of modality de re, the idea that objects have both essential and accidental properties. Plantinga develops his argument by means of the notion of possible worlds and ranges over such key problems as the nature of essence, transworld identity, negative existential propositions, and the existence (...) of unactual objects in other possible worlds. He also applies his logical theories to the elucidation of two problems in the philosophy of religion: the problem of evil and the ontological argument. (shrink)

Leibniz' Prinzip des zureichenden Grundes soll hier aufgrund von Russells Begriff des ‛logischen Eigennamens’ untersucht werden. Aus dieser Sicht kann vor der Schöpfung Gottes Begriff von Individuen keine individuelle Diesheit haben, sondern nur eine vollständige Beschreibung der noch nicht existierenden Individuen. Daraus ergibt sich, daß ein und dasselbe Individuum nicht durch mehr als eine Weltbeschreibung identifiziert werden kann, und darin darf man folglich Leibniz' tatsächlichen Beweis für die These des ‛Superessentialismus’ sehen, demzufolge alle Individuen ihre gesamten Eigenschaften mit Ausnahme der (...) Existenz wesenhaft besitzen. Im weiteren wird der Begriff einer Art möglicher Welten, die wir ‛parasitisch’ nennen wollen, erforscht. Dieser Begriff wird Leibniz' theoretischen Voraussetzungen gerecht, ohne zu seinen wenig überzeugenden Schlüssen zu führen. (shrink)
