Overriding evidence

I really have a hard time understanding the point of this section.

What difference is there between calculating the posterior given an evidence -- thus updating the future prior -- and questioning the prior "in the first place"? Isn't this the whole point of the process? to examine the prior and question it in case of an extraordinary evidence?
