Book excerpt: This book clarifies differences between the intellectual positions of the so-called two-party system of liberals and conservatives in American Protestant Christianity. Nancey Murphy advances the thesis that the philosophy of the modern period is largely responsible for the polarity of Protestant Christian thought. A second thesis is that the modern philosophical positions driving the division between liberals and conservatives have themselves been called into question. This, then, presents the opportunity to ask how theology ought to be done in a postmodern era and to envision a rapprochement between theologians of the left and right. The book concludes by speculating on the future and the likelihood that the compulsion to separate into two distinct camps will be precluded by the coexistence of a wide range of theological positions from left to right.
