The following are links to Paul Manata unofficial and withdrawn article:
Do All Men Know that God Exists? by Paul Manata
I say "withdrawn" because he had previous removed the article from his blog because it was a speculative paper. Though, sometime after he withdrew it, I personally asked him [around 2013] whether I could post the archived version of the paper on my blogposts He said it was alright to do so.
