This is a common idea, made by many people, notably Jordan Peterson. I have held this view i the past on the forum.
This video supposedly ‘debunks’ the notion:
I am not knowledgeable enough to respond (my field of expertise is in the Ancient Near East), however I will say that there is a competent case to be made that Western ‘Science’ is grounded in Christian values, as James Hannam and others have shown, and I think that RationalityRules ignores this. I am also aware that notable classical historian Tom Holland believes that Western Civilisation owes more to Christianity than to Ancient Greece.
What do you think?
