Dan Barker says: “None of the ‘evidences’ [for God] proves a supernatural being, so those who continue to believe are acting irrationally.” (Godless, 90)
Assuming that Barker’s claim that there are no proofs for God (i.e. proof by logical necessity or beyond a reasonable doubt) is true, which evidences against God disprove a supernatural being?
None, of course.
So atheists, by Barker’s standard, are irrational.
But here’s the next question: does Barker have evidences that prove that proof is the standard required for rationality? Of course not.
So it turns out that Barker’s position is self-defeating.
