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.

The purpose of this essay is to both discuss commands as a species of speech act and to discuss commands within the broader framework of how they are used and reacted to.

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.
