I disagree with this one. If you scrupulously include every disclaimer and caveat, you'll be too boring for anyone to pay attention to. It's better to be pragmatic. Giving someone an improved but still not maximally-accurate belief is still an improvement.
I propose that the author of this quote is placing a moral value on people possessing maximally accurate beliefs. If so, the author's moral system is incompatible with Standard Utilitarianism, is it not?
