One more attempt, my fellow philosophers:
"There is no God. The physical universe is all there is or ever has been."
"There is a triune God who created everything and who hears and answers our prayers."
Both of these metaphysical positions can have epistemological justification. Both are held by philosophers, theologians, Nobel laureates and others of the highest intellectual caliber.
Both are held by True Believers (or Non-Believers, as the case may be) for pretty much mindless reasons having nothing to do with the truth of the position. If I say there is no God because babies wouldn't die of terrible diseases if there were, this is not an epistemologically justified position.
EITHER POSITION COULD BE TRUE. BOTH COULD BE FALSE. BOTH CAN BE EPISTEMOLOGICALLY JUSTIFIED.
I want my position on the JFKA to be as justified as I can make. At least in my own mind, I want to be able to explain it to myself in a way that seems rational, coherent, realistic (plausible), that confronts and deals with the problem areas, and that I can articulate and defend if I need to do so.
It seems to me - perhaps you disagree or don't care - that an awful lot of CTers don't feel the need for much if any epistemological justification for THEIR OWN BELIEFS and rather obviously avoid articulating and defending them if called upon to do so. Witness my CE-399 thread where only Martin even took a stab at addressing my very basic "What sense does that make?" questions. They are rather curiously content with just "a" conspiracy.
In the abstract, a conspiracy theory with Oswald as a complete patsy, multiple three-man kill teams and LBJ at the helm COULD BE as epistemologically justified as the LN narrative. That's why I'm still waiting, waiting for someone to provide a plausible, realistic set of answers to "What sense would have that have made? Why would the conspirators have done that? How would that actually have worked, from the time it was a gleam in someone's eye until all was said and done?"
