The Interpretation of History

Tillich discusses the boundaries that have determined his life, the boundaries between the different temperaments of his mother and father, between city and country, between social classes, between reality and imagination, between theory and practice, between heteronomy and autonomy, between theology and philosophy, between church and society, between religion and culture, between Lutheranism and socialism, between idealism and Marxism, between home and alien land, and, in retrospect, some limitations on the boundary concept.
