Three Philosophers presents the life-histories of Antoine-Laurent Lavoisier, Joseph Priestley, and Henry Cavendish. This book discusses the discovery of the composition of water marks, which is the birth of modern chemical science. Organized into 19 chapters, this book begins with an overview of the biographical background of Antoine-Laurent Lavoisier, who contributed largely to chemistry and physics. This text then discusses Lavoisier's role as the virtual founder of the science of nutrition, in the sense that he originated methods of enquiry in this field which were the basis of almost all later developments. Other chapters illustrate Lavoisier in his capacity of progressive social reformer. This book discusses as well the experimental work on oxygen consumption, which is commonly known as metabolism nowadays. The final chapter deals with the death of two great philosophers, Joseph Priestley and Henry Cavendish. This book is a valuable resource for students, teachers, and research workers.

"I've been a philosopher for all my adult life and the three most profound books of philosophy that I have ever read are Ecclesiastes, Job, and Song of Songs." These are the opening lines of Kreeft's Three Philosophies of Life. He reflects that there are ultimately only three philosophies of life and each one is represented by one of these books of the Bible-life is vanity; life is suffering; life is love. In these three books Kreeft shows how we have Dante's great epic The Divine Comedy played out, from Hell to Purgatory to Heaven. But it is an epic played out in our hearts and lives, here and now. Just as there is movement in Dante's epic, so there is movement in these books, from Ecclesiates to Job, from Job to Song of Songs. Love is the final answer to Ecclesiastes' quest, the alternative to vanity, and the true meaning of life. Finally, Kreeft sees in these books the epitome of theological virtues of faith, hope and love and "an esstential summary of the spiritual history of the world".

To desire something is a condition familiar to everyone. It is uncontroversial that desiring has something to do with motivation, something to do with pleasure, and something to do with reward. Call these "the three faces of desire." The standard philosophical theory at present holds that the motivational face of desire presents its unique essence--to desire a state of affairs is to be disposed to act so as to bring it about. A familiar but less standard account holds the hedonic face of desire to reveal to true nature of desire. In this view, to desire something is to tend to pleasure if it seems that the desired state of affairs has been achieved, or displeasure if it seems otherwise, thus tying desire to feelings instead of actions. In Three Faces of Desire, Schroeder goes beyond actions and feelings to advance a novel and controversial theory of desire that puts the focus on desire's neglected face, reward. Informed by contemporary science as much as by the philosophical tradition, Three Faces of Desire discusses recent scientific discoveries that tell us much about the way that actions and feelings are produced in the brain. In particular, recent experiments reveal that a distinctive system is responsible for promoting action, on the one hand, and causing feelings of pleasure and displeasure, on the other. This system, the brain's reward system, is the causal origin of both action and feeling, and is the key to understanding the nature of desire.

Alasdair MacIntyre—whom Newsweek has called "one of the foremost moral philosophers in the English-speaking world"—here presents his 1988 Gifford Lectures as an expansion of his earlier work Whose Justice? Which Rationality? He begins by considering the cultural and philosophical distance dividing Lord Gifford's late nineteenth-century world from our own. The outlook of that earlier world, MacIntyre claims, was definitively articulated in the Ninth Edition of the Encyclopaedia Brittanica, which conceived of moral enquiry as both providing insight into and continuing the rational progress of mankind into ever greater enlightenment. MacIntyre compares that conception of moral enquiry to two rival conceptions also formulated in the late nineteenth century: that of Nietzsche's Zur Genealogie der Moral and that expressed in the encyclical letter of Pope Leo XIII Aeterni Patris. The lectures focus on Aquinas's integration of Augustinian and Aristotelian modes of enquiry, the inability of the encyclopaedists' standpoint to withstand Thomistic or genealogical criticism, and the problems confronting the contemporary post-Nietzschean genealogist. MacIntyre concludes by considering the implications for education in universities and colleges.

This collection provides an excellent introduction to three of the most important names in twentieth-century Spanish philosophy: Miguel de Unamuno (1864–1936), José Ortega y Gasset (1883–1955), and José Ferrater Mora (1912–1991). The thought-provoking work of these great contemporary philosophers offers a rich and penetrating insight into human existence. Originally written by Ferrater Mora in the middle of the last century, his interpretations of Unamuno and Ortega are considered classics, and the chapter on his own thought reflects his mature thinking about being and death. Each essay is introduced by noted Ferrater Mora scholar J. M. Terricabras and contains updated biographical and bibliographic information.

Conjectures and Refutations is one of Karl Popper's most wide-ranging and popular works, notable not only for its acute insight into the way scientific knowledge grows, but also for applying those insights to politics and to history. It provides one of the clearest and most accessible statements of the fundamental idea that guided his work: not only our knowledge, but our aims and our standards, grow through an unending process of trial and error.
