A priori and a posteriori knowledge/Talk

Unfortunately MOST of the following is not about a priori and a posterori knowlege at all, so I'm moving it here, and replacing it with a less controvercial, and more consise stub. Perhaps we'll be able to find a home for all of this, but I don't think this page is it MRC

Then, Mark, please move it to an appropriately-named page; don't just leave nothing on the page. --LMS
