It's definitely received wisdom that may once have been right and no longer is. Most people are not used to facts having a half-life, but many facts do, or, rather, much knowledge, does. We feel very secure in knowing what we know, and the reality is that we need to be willing to question a lot of things, like authority, including our very own. Now, we can't be questioning everything all the time because that way madness lies, but we can't never question anything we think we know either! Epistemology is hard. I want a doll that says that when you pull the cord.
