If the philosophers of the Enlightenment had hoped to establish, once and for all, that reason is the primary source of human orientation, twentieth century philosophy has demonstrated all too clearly that reason is far from having clear boundaries. In this respect, Immanuel Kant’s contemporaries and critics, Johann Georg Hamann and Friedrich Heinrich Jacobi, look surprisingly modern. Faith is now increasingly recognized as intrinsic to social identity and thus no more capable of taking a permanently subordinate role to reason—whatever that may be—than reason is capable of an existence free from social embodiment. This collection of thirteen essays focuses upon major philosophical and theological debates from the past three hundred years. Written by leading international scholars, this remarkable text takes the reader through major transitions in the modern understanding of faith and reason. It thus provides an invaluable guide to the history of modern philosophical theology whilst informing readers why the relationship between faith and reason remains an issue of major social and philosophical importance.
