Offering a new approach to scientific explanation, this book focuses initially on the explaining act itself. From that act, a "product" emerges: an explanation. To understand what that product is, as well as how it can be evaluated in the sciences, reference must be made to the concept of the explaining act. Following an account of the explaining act, its product, and the evaluation of explanations, the theory is brought to bear on these issues: Why have the standard models of scientific explanation been unsuccessful, and can there be a model of the type sought? What is causal explanation, and must explanation in the sciences be causal? What is a functional explanation? The "illocutionary" theory of explanation developed at the outset is used in discussing these issues, and contrasting philosophical viewpoints are assessed.

This book looks at the relationship between the structure of the sentence and the organization of discourse. While a sentence obeys specific grammatical rules, the coherence of a discourse is instead dependent on the relations between the sentences it contains. In this volume, leading syntacticians, semanticists, and philosophers examine the nature of these relations, where they come from, and how they apply. Chapters in Part I address points of sentence grammar in different languages, including mood and tense in Spanish, definite determiners in French and Bulgarian, and the influence of aktionsart on the acquisition of tense by English, French, and Chinese children. Part II looks at modes of discourse, showing for example how discourse relations create implicatures and how Indirect Discourse differs from Free Indirect Discourse. The studies conclude that the relations between sentences that make a discourse coherent are already encoded in sentence grammar and that, once established, these relations influence the meaning of individual sentences.
