In the proliferation of new books on theology and science, this book is unique in its special focus on the problem of rationality in religion and scientific reflection. Confronting head-on the intellectual challenges raised by postmodern thought, J. Wentzel van Huyssteen argues forcefully for the interdisciplinary nature and public status of theological reflection. Building on the line of argument pursued in his most recent writings, the author develops his notion of "postfoundationalist rationality," finding within the rich resources of human thought the possibility -- and vital need -- for interdisciplinary conversation between theology and science.
