 The most active discussions of natural theology in the West occurred during the high medieval period (roughly 1100–1400 C.E.) and the early modern period (1600–1800 C.E.). The past few decades have witnessed a revival of natural theological debate in the public sphere: there are now institutes promoting “Intelligent Design Theory”, popular apologetics courses, campus debates between believers and agnostics, a “New Atheist” movement, Youtube debates between apologists and atheists regarding new books in natural theology (such as the one between Nathan Lewis and Bernie Dehler on the Blackwell Companion to Natural  Theology),[2]  and TED talks by famous atheists on how to resist natural religion (such as the one by Richard Dawkins in February  2002).[3]
