Teleology is the belief that some things happen, or exist for the sake of other things. It is the belief that, for example, salmon swim upstream in order to spawn, and that bears have claws for the sake of catching fish. This volume takes up the intuitive yet puzzling concept of teleology as it has been treated by philosophers from ancient times to the present day. It includes nine main chapters centered on the treatment of teleology in Plato, Aristotle, the Islamic medieval tradition, the Jewish medieval tradition, the Latin medieval tradition, the early modern era, Kant, Hegel, and contemporary philosophy. Each chapter probes central questions such as: is teleology inherent in its subjects or is it imposed on them from the outside? Does teleology necessarily involve intentionality, that is, a subject's cognizing some end, goal, or purpose? What is the scope of teleology? Is it, for example, applicable to elements and animals, or only to rational beings? Finally, is teleology explanatory? When we say that salmon swim upstream in order to spawn, have we explained why they swim upstream? When we say that bears have claws for catching fish, have we explained why bears have claws? The philosophical discussions of the main chapters are enlivened and contextualized by four reflection pieces exploring the implications of teleology in medicine, art, poetry, and music.

Does God exist? What is the nature of evil, and where does it come from? Are humans free? Responsible? Immortal? Does it matter? Saints, Heretics and Atheists offers a historical introduction to fundamental questions in the philosophy of religion. Ranging from ancient times to the twentieth century, it is divided into twenty-five succinct, chronological chapters. Individual chapters discuss philosophies from history's greatest thinkers including Plato, Augustine, al-Ghazali, Aquinas, Margarite Porte, Spinoza, Hume, Mary Shepherd, and Nietzche. The book closes with an exploration of William James's defense of the right to believe, possible limitations of that right, and the nature of philosophical progress. Based on lectures from a popular course taught in the Program for General Education at Harvard University for over a decade, Saints, Heretics, and Atheists invites readers along for a journey that is unique in its sweeping historical approach to the philosophy of religion and the balance it strikes between traditional, non-traditional, and atheistic standpoints with respect to religion in the western tradition.

A rival to Isaac Newton in mathematics and physics, Gottfried Wilhelm Leibniz believed that our world--the best of all possible worlds--must be governed by a principle of optimality. This book explores Leibniz's pursuit of optimality in five of his most important works in natural philosophy and shows how his principle of optimality bridges his scientific and philosophical studies. The first chapter explores Leibniz's work on the laws of optics and its implications for his defense of natural teleology. The second chapter examines Leibniz's work on the breaking strength of rigid beams and its implications for his thinking about the metaphysical foundations of the material world. The third chapter revisits Leibniz's famous defense of the conservation of vis viva and proposes a novel account of the origin of Leibniz's mature natural philosophy. The fourth chapter takes up Leibniz's efforts to determine the shape of freely hanging chains--the so-called problem of the catenary--and shows how that work provides an illuminating model for his thinking about the teleological structure of wills. Finally, the fifth chapter uses Leibniz's derivation of the path of quickest descent--his solution to the so-called problem of the Brachistochrone--and its historical context as a springboard for an exploration of the legacy of Leibniz's physics. The book closes with a brief discussion of the systematicity of Leibniz's thinking in philosophy and the natural sciences.
