"I have always taken the view that there was a Jesus of history. Now I'm not so sure. His new 700 page book "On the Historicity of Jesus: Why We Might Have Reason for Doubt" is on my wish list."
I'm sure the same logic can be applied to Mohammed and other leaders who started their respective religions.
I have not read Richard Carrier's book but if he follows that same logic as others who say the same thing then he is questioning the existence of Jesus simply because he was mythologized by his early followers. So what if Jesus is pictured as a pagan demi-god? The same thing could happen to any other charismatic leader that actually existed.
