Questionorientedness And The Semantics of Clausal Complementation

Abstract objects have been a central topic in philosophy since antiquity. Philosophers have defended various views about abstract objects by appealing to metaphysical considerations, considerations regarding mathematics or science, and, not infrequently, intuitions about natural language.

This book provides a formal ontology of senses and the belief-relation that grounds the distinction between de dicto, de re, and de se beliefs as well as the opacity of belief reports.

Natural Language is not only the most important means of communication between human beings, it is also used over historical periods for the pres- vation of cultural achievements and their transmission from one generation to the other.
