This book studies the philosophies of Paul Tillich. Its focus is on justice, covering two dimensions of justice. The first is the social dimension, manifested in human relationships. The second dimension is at the individual level, seen in each person's struggle to feel a secure sense of selfhood. The author also explores Tillich's concept of the contrast between the self and the world. He explains how the self cannot exist without a world and the world cannot exist without the self. The author goes on to cover Tillich's belief in self doubt as well as the possibilities of human fulfillment.
