I like this story.
But it seems there some equivocation or similar confusion around here:
if any painting has an equal chance of being a Pablo, then seeing this painting doesn't tell us anything--it can't count as evidence either way.
If I know nothing about Pablo's methods and so can't tell whether any painting is a Pablo painting, why should I expect that seeing a genuine Pablo painting will tell me anything. Particularly since it seems like I already learned something from this painting - I don't understand Pablo's methods.
These are written from the angle that Christians deconverting is bad.
Cognitive reasons
Breaking up because a relationship with God becomes unworkable
Leaving because other Christians aren't empathetic about doubt
At what age do people leave?
It looks as though there may be more articles in the series.
