44The early, largely automatic stages of human visual processing involve things like feature detectors (e.g., edge detectors) that do not involve our concepts or beliefs. These stages are called data-driven or bottom up aspects of perceptual information processing. But in the later stages of processing perception often is affected by our concepts, beliefs, and expectations. Such processes are said to be hypothesis-driven or expectation-driven; they are also known as..

68Many linguists, including Noam Chomsky, contend that language in the sense we ordinary think of it, in the sense that people in Germany speak German, is a historical or social or political notion, rather than a scientific one. For example, German and Dutch are much closer to one another than various dialects of Chinese are. But the rough, commonsense divisions between languages will suffice for our purposes.

1Leibniz's calculus of real additionStudia Leibnitiana 26 (1): 1-30. 1994.In der vorliegenden Arbeit wird Leibniz' wahrscheinlich detailliertestes und ausgefeiltestes System untersucht: ein Kalkül der Einfügung und eine der Konjunktion ähnliche Operation, die er realis abjectio nennt. Das System soll hinreichend detailliert und mit hinreichender Präzision vorgestellt werden, um zu zeigen, daβ es ausgefeilt formal logisch ist und eine Anzahl originärer und wichtiger Züge aufweist. Neben seinem eigenständigen Interesse ist dieses System wichtig wegen seiner Auswirkungen…Read more

235Complex predicates and logics for properties and relationsJournal of Philosophical Logic 27 (3): 295-325. 1998.In this paper I present a formal language in which complex predicates stand for properties and relations, and assignments of denotations to complex predicates and assignments of extensions to the properties and relations they denote are both homomorphisms. This system affords a fresh perspective on several important philosophical topics, highlighting the algebraic features of properties and clarifying the sense in which properties can be represented by their extensions. It also suggests a natura…Read more
