Also Camotero as much as you are comfortable and think it would be helpful I would encourage you to give us more background about yourself and your reading so far and anything about the direction of your thought that would be helpful for us all to communicate more clearly. It particularly gives me food for thought to realize that you have been listening to the podcasts without knowing the background of the principal doctrines. It's possible that I need to add to our introductions some more basic pointers about what is presumed to be understood, and what the listener should check out if they haven't already. I know we do stress the DeWitt book in the opening of the podcasts but it would be easy for us to include or at least reference where other preliminary material can be found.
Here on this page we have the FAQ and the Core Texts menu but I shouldn't presume those are easy to find.
