Paul Tillich's Philosophical Theology takes up the challenge as to whether Tillich's thought remains relevant fifty years after his death. On the one hand, Tillich's systematic approach might mark him out as representing the kind of metaphysical thought critiqued by postmodernism, suggesting that he has relatively little to say to us today. However, drawing on his early research on Schelling, his religious socialism, his writings on art, and his preaching, as well as on his more systematic writings, the book argues that his thought is in many respects exemplary of open theological engagement with the contemporary intellectual situation.
