I have never doubted that individuals, especially religious individuals, can be illogical and simultaneously hold diametrically opposite views. "Frankly why would a non mechanist be solipsist?" Although it can not be proven to be false no sane person can be a solipsist, except perhaps in a philosophy classroom when they are trying to sound provocative. A better question would be why would anyone think it controversial to say "things happen for a reason or they do not"?
