Abstract

In order to illuminate the similarities and differences between science and theology, we consider an epistemology and methodology for each that can be characterised as a dialectical critical realism. Our approach is deeply indebted to the work of the great Swiss theologian, Karl Barth. Key points are that the object under study determines the method to be used, the community of investigators and the nature of the possible knowledge to be gained; the necessity of a posteriori, rather than a priori reasoning; and that the dialogue between theology and science should account for both the similarities and differences between the two disciplines. The counterintuitive nature of quantum physics is used to illustrate how in science the dialectic element should lead to a critical dimension to realism, and one is forced to engage with reality on its own terms.
