The three periods of ‘lift’ that he identifies were anything but periods of secular thought. Contrary to the popular claims about logos replacing mythos in ancient Greece and this being the reason for the birth of Greek science, if you actually look at the works of the leading Greek thinkers they are full of religious claims and statements. Turning to the Renaissance all of the major figures who erected the structure that became modern science were deeply and actively religious, a fact that they openly acknowledge in their scientific writings. Again in the 18th century the period of both the Enlightenment and the Industrial Revolution nearly all of the leading participants were again deeply and actively religious.
As I have pointed out more than once on this blog the Church was not anti-scientific during the Middle Ages and in fact members of the Church actively laid the foundations on which other members of the Church created modern science in the Early Modern Period.
I did not know that the New Atheists had started an Orwellian revisionist rewriting of history.
