For nineteenth-century thinkers, the central problem of religious consciousness in the modern West was the tension between prevailing concepts of individual autonomy and the traditional Judaeo-Christian claim for divine revelation. The God Within brings together ten of Professor Emil Fackenheim's essays on the German Idealists who struggled to resolve this tension. All the essays gathered here are concerned with the radical singularity of history and existence on the one hand and the demands of philosophical truth on the other. They are informed by Professor Fackenheim's engagement with the profound philosophical challenges of our day - particularly his efforts, as a Jewish theologian, to confront the horrors of the Holocaust. We see, through Fackenheim's exposition, how these thinkers sought to come to terms with the presence of radical evil, a problem whose modern relevance is explored in this volume's epilogue, the 1988 essay 'Holocaust and Weltanschauung: Philosophical Reflections on Why They Did It.'.
