Alister McGrath's work on the relationship between Science and Theology makes the most notable contribution to the subject written by an evangelical in recent history. McGrath holds earned doctorates in both science and theology, and his three volume set, A Scientific Theology, is the culmination of three decades of his work on the subject. In this book, James K. Dew explores McGrath's contribution to the issue and highlights the benefits of adopting a critical realist perspective such as his own. In particular, Dew argues that McGrath's approach helps establish a unified theory of knowledge, and holds significant advantages for scientists and theologians alike.
