Spanning the history of western philosophy as well as looking toward classical Chinese thought and medieval Islamic philosophy, this volume provides business ethicists a unified source of clear, accurate, and compelling accounts of how the ideas of foundational thinkers--from Aristotle to Friedrich Hayek to Amartya Sen--relate to wealth, commerce, and markets. The essays illuminate perspectives that have often been ignored or forgotten, informing discussion in fresh and often unexpected ways. In doing so, the authors not only throw into relief common misunderstandings and misappropriations often endemic to business ethics but also set forth rich moments of contention as well as novel ways of approaching complex ethical problems. Ultimately, this volume provides a bedrock of moral thought that will move business ethics beyond the ever-changing opinions of headline-driven debate.
