The Catholicity of Reason explains the 'grandeur of reason,' the recollection of which Benedict XVI has presented as one of the primary tasks in Christian engagement with the contemporary world. While postmodern thinkers -- religious and secular alike -- have generally sought to respond to the hubris of Western thought by humbling our presumptuous claims to knowledge, D. C. Schindler shows in this book that only a robust confidence in reason can allow us to remain genuinely open both to God and to the deep mystery of things. Drawing from both contemporary and classical theologians and philosophers, Schindler explores the basic philosophical questions concerning truth, knowledge, and being -- and proposes a new model for thinking about the relationship between faith and reason. The reflections brought together in this book bring forth a dramatic conception of human knowing that both strengthens our trust in reason and opens our mind in faith.
