Study on the logic of normative discourse.

Imperative clauses are recognized as one of the major clause types alongside those known as declarative and interrogative. Nevertheless, they are still an enigma in the study of meaning, which relies largely on either the concept of truth conditions or the concept of information growth—neither of which are easily applied to imperatives. This book puts forward a fresh perspective. It analyzes imperatives in terms of modalized propositions, and identifies an additional, presuppositional, meaning component that makes an assertive interpretation inappropriate. The author shows how these two elements can help explain the varied effects imperatives have, depending on their usage context. Imperatives have been viewed as elusive components of language because they have a range of functions that makes them difficult to unify theoretically. This fresh view of the semantics-pragmatics interface allows for a uniform semantic analysis while accounting for the pragmatic versatility of imperatives.

Originally published in 1966. Professor Rescher’s aim is to develop a "logic of commands" in exactly the same general way which standard logic has already developed a "logic of truth-functional statement compounds" or a "logic of quantifiers". The object is to present a tolerably accurate and precise account of the logically relevant facets of a command, to study the nature of "inference" in reasonings involving commands, and above all to establish a viable concept of validity in command inference, so that the logical relationships among commands can be studied with something of the rigour to which one is accustomed in other branches of logic.

Edited in collaboration with FoLLI, the Association of Logic, Language and Information, this book constitutes the refereed proceedings of the Third International Workshop on Logic, Rationality, and Interaction, LORI 2011, held in Guangzhou, China, in October 2011. The 25 revised full papers presented together with 12 posters were carefully reviewed and selected from 52 submissions. Among the topics covered are semantic models for knowledge, for belief, and for uncertainty; dynamic logics of knowledge, information flow, and action; logical analysis of the structure of games; belief revision, belief merging; logics and preferences, compact preference representation; logics of intentions, plans, and goals; logics of probability and uncertainty; logical approaches to decision making and planning; argument systems and their role in interaction; norms, normative interaction, and normative multiagent systems; and logical and computational approaches to social choice.

The legendary Greek figure Orpheus was said to have possessed magical powers capable of moving all living and inanimate things through the sound of his lyre and voice. Over time, the Orphic theme has come to indicate the power of music to unsettle, subvert, and ultimately bring down oppressive realities in order to liberate the soul and expand human life without limits. The liberating effect of music has been a particularly important theme in twentieth-century African American literature. The nine original essays in Black Orpheus examines the Orphic theme in the fiction of such African American writers as Jean Toomer, Langston Hughes, Claude McKay, James Baldwin, Nathaniel Mackey, Sherley Anne Williams, Ann Petry, Ntozake Shange, Alice Walker, Gayl Jones, and Toni Morrison. The authors discussed in this volume depict music as a mystical, shamanistic, and spiritual power that can miraculously transform the realities of the soul and of the world. Here, the musician uses his or her music as a weapon to shield and protect his or her spirituality. Written by scholars of English, music, women's studies, American studies, cultural theory, and black and Africana studies, the essays in this interdisciplinary collection ultimately explore the thematic, linguistic structural presence of music in twentieth-century African American fiction.

Muslims have always used verses from the Qur'an to support opinions on law, theology, or life in general, but almost no attention has been paid to how the Qur'an presents its own precepts as conclusions proceeding from reasoned arguments. Whether it is a question of God's powers of creation, the rationale for his acts, or how people are to think clearly about their lives and fates, Muslims have so internalized Qur'anic patterns of reasoning that many will assert that the Qur'an appeals first of all to the human powers of intellect. This book provides a new key to both the Qur'an and Islamic intellectual history. Examining Qur'anic argument by form and not content helps readers to discover the significance of passages often ignored by the scholar who compares texts and the believer who focuses upon commandments, as it allows scholars of Qur'anic exegesis, Islamic theology, philosophy, and law to tie their findings in yet another way to the text that Muslims consider the speech of God.
