Science, especially naturalistic science, has come under fire of late. No longer does it command the near universal respect it once held. From the right has come a fresh attack on Darwinism and arguments for intelligent design. From the left postmodernist theorists have attacked the very notion of objective truth claims, scientific or otherwise. Into the fray Del Ratzsch breathes a breath of calm. He asks, What is science? What can it tell us? What can it not tell us? What challenges does it offer to Christian faith? How should a Christian respond?
