Tradition in an Untraditional Age, first published in 1990, explores the challenges of secularisation, assimilation and antisemitism, through analyses of thinkers including R. Samson Raphael Hirsch, R. Moses Sofer, R. Abraham Isaac Kook, R. Joseph Soloveitchik, Franz Rosenzweig and Martin Buber, as well as studies of topics including the Holocaust, Jewish-Christian dialogue, Jewish economic ethics and religious alienation and return. It also sets out an agenda for future Jewish thought.
