Book excerpt: 'What does it mean to be a human being?' Given this perennial question, Alasdair MacIntyre, one of America's preeminent philosophers, presents a compelling argument on the necessity and importance of philosophy. Because of a need to better understand Catholic philosophical thought, especially in the context of its historical development and realizing that philosophers interact within particular social and cultural situations, MacIntyre offers this brief history of Catholic philosophy. Tracing the idea of God through different philosophers' engagement of God and how this engagement has played out in universities, MacIntyre provides a valuable, lively, and insightful study of the disintegration of academic disciplines with knowledge. MacIntyre then demonstrates the dangerous implications of this happening and how universities can and ought to renew a shared understanding of knowledge in their mission. This engaging work will be a benefit and a delight to all readers.
