As a matter of course I expect most things I read here to be based on works from other sources or reinventions thereof.

As an aside I would expect Eliezer to have far less to cover in the field of argumentation than many other potential explorers. He tries to cut himself off from a lot of the paths of argumentation that are paved in filth which means he doesn't follow them along enough to really understand the sophisticated nuances. One would expect make his writing more useful for 'how to not' than 'how to'.
