The long and rich tradition of the Gifford Lectures challenges the feasibility and credibility of modern dialogues between theology and the sciences. J. Wentzel van Huyssteen rejects the idea that religious faith and scientific thought inhabit opposing domains of rationality. He argues that these seemingly incompatible reasoning strategies actually share in the resources of human rationality and should, therefore, be able to be linked in interdisciplinary dialogue. Van Huyssteen sets the stage for developing themes strongly implicit in Lord Gifford’s charge: first, an integrative and interdisciplinary praxis for theology and the sciences; and second, the basic conviction that there is something uniquely human, constituted by the way we relate to ourselves, to the world and to God.
