This collection of original essays examines the controversy over and attacks on rationality in the methodologies of the humanities and the physical and social sciences. These essays represent the thinking of a wide variety of philosophers, psychologists, historians, classicists, and economists about the role of rationality in thought and action. Reflecting the differing perspectives of their authors' disciplines, as well as the centrality of rationality to those disciplines, they are important additions to a debate that has been going on for some twenty years. Beginning with an introductory essay in which K.D. Irani covers the various ways in which rationality can be approached, the body of the book is divided into five sections dealing with various aspects of the issue. Respectively, they are concerned with rationality as it relates to ethical and social thought and action; general scientific thought and the particular disciplines of economics, history, and law; the analytic and hermenutic approaches to communications and learning; and the contrasting classical traditions of ancient Greece and China. In the final section, two differing theories concerning the nature of rationality itself are presented. A list of suggested further readings completes the volume.

Isaac Newton wrote the manuscript Questiones quaedam philosophicae at the very beginning of his scientific career. This small notebook thus affords rare insight into the beginnings of Newton’s thought and the foundations of his subsequent intellectual development. The Questiones contains a series of entries in Newton’s hand that range over many topics in science, philosophy, psychology, theology, and the foundations of mathematics. These notes, written in English, provide a very detailed picture of Newton’s early interests, and record his critical appraisal of contemporary issues in natural philosophy. Written predominantly in 1664–5, they give a significant perspective on Newton’s thought just prior to his annus mirabilis, 1666. This volume provides a complete transcription of the Questiones, together with an ‘expansion’ into modern English, and a full editorial commentary on the content and significance of the notebook in the development of Newton’s thought. It will be essential reading for all those interested in Newton and the intellectual foundations of science.
