The last three decades have witnessed a heated debate of the merits of intelligent design (ID) as a way to understand a number of observable natural phenomena. The present dispute has its roots in a much older discussion: that of natural theology, which has always had as its goal the discernment of design(s) attributable to God in the natural world. Despite its ongoing relevance, natural theology does not have a coherent scholarly history. Turning Points in Natural Theology from Bacon to Darwin deftly fills that gap, analysing the argument of design during the period from Francis Bacon (1561-1626) to Charles Darwin (1809-82), with a specific focus on those moments at which the rhetorical terms changed significantly.
