Normative reasons have become a popular theoretical tool in recent decades. One helpful feature of normative reasons is their weight. The fourteen new essays in this book theorize about many different aspects of weight. Topics range from foundational issues to applications of weight in debates across philosophy.

John Broome has made major contributions to, and radical innovations in, contemporary moral philosophy. His research combines the formal method of economics with philosophical analysis. Broome's works stretch over formal axiology, decision theory, philosophy of economics, population axiology, the value of life, the ethics of climate change, the nature of rationality, and practical and theoretical reasoning. Weighing and Reasoning brings together fifteen original essays from leading philosophers who have been influenced by the work and thought of John Broome. It aims to offer a comprehensive evaluation of Broome's wide-ranging and far-reaching philosophical works over the past thirty years. The volume comprises two parts. The first part is focused on Broome's work on the theory of value, as exemplified in his books Weighing Goods, Weighing Lives, Economics out of Economics, and Climate Matters. The second part is focused on his work on practical and theoretical reasoning, which culminated in his Rationality through Reasoning. This volume also includes a piece by Broome on his intellectual history to date.

In recent decades normative reasons-considerations that count in favor of one thing or another-have come to the theoretical fore in ethics and epistemology. A major attraction of normative reasons is that they have weight or strength. Reasons are particular considerations that count in favor of actions or attitudes to some degree. This feature is attractive to theorists who want to explain more complex normative phenomena in terms of a notion that is weighted. This volume aims to provide the beginnings for a theory of weight. The fourteen new essays fall into three groups. One set of essays addresses questions about the nature of weight. Topics include the relations between reasons and conditions and modifiers, between reasons and other weighted notions such as commitments, and different models of the interaction of reasons. A second set of essays addresses substantive questions: questions about weight relevant to value-first, desire-first, evidence-first and other normative research programs. A third set of essays applies issues in the theory of weight to broader ethical debates. The book thus not only makes novel contributions to debates in ethics and epistemology about the nature of normative reasons and their weight, it also makes a strong case for the theoretical fruitfulness of the ideology of normative reasons.

Rationality Through Reasoning answers the question of how people are motivated to do what they believe they ought to do, built on a comprehensive account of normativity, rationality and reasoning that differs significantly from much existing philosophical thinking. Develops an original account of normativity, rationality and reasoning significantly different from the majority of existing philosophical thought Includes an account of theoretical and practical reasoning that explains how reasoning is something we ourselves do, rather than something that happens in us Gives an account of what reasons are and argues that the connection between rationality and reasons is much less close than many philosophers have thought Contains rigorous new accounts of oughts including owned oughts, agent-relative reasons, the logic of requirements, instrumental rationality, the role of normativity in reasoning, following a rule, the correctness of reasoning, the connections between intentions and beliefs, and much else. Offers a new answer to the ‘motivation question’ of how a normative belief motivates an action.

Philosophers have long been concerned about what we know and how we know it. Increasingly, however, a related question has gained prominence in philosophical discussion: what should we believe and why? This volume brings together twelve new essays that address different aspects of this question. The essays examine foundational questions about reasons for belief, and use new research on reasons for belief to address traditional epistemological concerns such as knowledge, justification and perceptually acquired beliefs. This book will be of interest to philosophers working on epistemology, theoretical reason, rationality, perception and ethics. It will also be of interest to cognitive scientists and psychologists who wish to gain deeper insight into normative questions about belief and knowledge.

A comprehensive survey of traditional and contemporary views on the Qur'an, including textual, historical, sociological, philosophical, aesthetic, linguistic and experiential, brought together in an effort to ascertain whether Islam's sacred book is the word of God, as it claims to be, or not. Readers will find here the earliest ancient sources and the latest scientific studies uniquely confronted to shed objective light on this important topic.

This study uses techniques from economics to illuminate fundamental questions in ethics, particularly in the foundations of utilitarianism. Topics considered include the nature of teleological ethics, the foundations of decision theory, the value of equality and the moral significance of a person's continuing identity through time.

What should I do? What should I think? Traditionally, ethicists tackle the first question, while epistemologists tackle the second. This volume is innovative in drawing together issues from epistemology and ethics and in exploring neglected connections between epistemic and practical normativity.

This volume is a selection of Broome's recent papers on normativity, rationality, and reasoning. It covers a variety of topics such as the meanings of 'ought', 'reason', and 'reasons'; the fundamental structure of normativity and the metaphysical priority of ought over reasons; the ownership - or agent-relativity - of oughts and reasons; the distinction between rationality and normativity; the notion of rational motivation; what characterizes the human activity of reasoning, and what is the role of normativity within it; the nature of preferences and of reasoning with preferences; and others. These papers extend the work presented in his book Rationality Through Reasoning but there is little overlap between their content and the book's. They develop further some themes and arguments from the book, and answer some questions that the book left unanswered.
