That's an error. In the end, it's only about what we choose to believe as long as what we choose to believe doesn't kill us! I wouldn't urge you to try it, but that was the point of my fork example or my leaping off the Sears Tower example. Only beliefs that have little adverse impact on our survival can afford to be irrational.
Hmmm. . I'd have to disagree. We all chose what we will believe. If what we believe kills us, we still made the choice to believe it. (Example: The homocide bombers).
