The Self-Stultifier

"As long as a person maintains that his beliefs represent an actual state of the world (visible or invisible, spiritual or mundane), he must believe that his beliefs are a consequence of the way the world is. This, by definition, leaves him vulnerable to new evidence. Indeed, if there were no conceivable change in the world that could get a person to question his ... beliefs, this would prove that his beliefs were not predicated upon his taking any state of the world into account" - Sam Harris, End of Faith, p.63

i) What about a person's belief in the law of non-contradiction? Is he "vulnerable" to new evidence? Could there be a "conceivable" change in the world that could get this person to question his belief? Isn't the LNC part of what allows something to even be conceivable in the first place?

ii) What about a person's belief in her existence? Is there a conceivable change that could get a person to question her existence? Who would be questioning it?

iii) What about Harris's belief on this matter? Is there a way the world could be that would make it false? Then it would still be true since this new belief a "consequence of the way the world is." A conceivable way the world could be that would make Harris question this belief would affirm his strictures and thus not make him "vulnerable." But a consequence of this view is that your beliefs must be "vulnerable" in this way.

Yawn, the "New" atheism.

Go Sammy, it's your birthday!
