The invention of a damnation meme allows the priest class to dominate society. In most pre-Abrahamist cultures the priest class only played a tangential, though often important, role in subservience to the warrior/ruling class. In many of these cultures true "spiritual salvation", in the form of after life rewards, was only available to the warrior class. Of course all pre-Abrahamic and non-Abrahamic religions were not warrior/ruler based, but most most were. Judaism was a universal-by-tribe religion while Christianity raised this to a universal-by-acceptance religion. Of course Islam began as a tribal religion using the wider meme "acceptance" method of Christianity.QED wrote: Of course some people know this as the transmission of memes. It's probably the main reason that the various Abrahamic religions are so dominant.
Abrahamism changed the "salvation" meme into a universal reward for obedience and elevated the priest class into the central social role by merging the warrior/ruling class into a armed servant of the priesthood. The "king" and the ruling class becomes first and foremost answerable to "God" ergo the priesthood. Universal reward strengthens the priesthood by ensuring social loyalty of all society members.
1). God-meme as universal perfect creator,
2). Damnation of humanity for imperfection,
3). Salvation through obedience to God (ergo priest class)
4). Punishment, both earthly and divine, for disobedience.
If the system wasn't so destructive it could be admired for it's brilliance at social manipulation. The logical holes are not readily apparent to any semi-literate culture and the meme is universally enforced through violence. Only in the last few centuries have Christians feared damnation by God more than damnation by the priest class, and in the Islamic world the damnation by the priest class remains the major method of meme enforcement. It is rather difficult over generations not to accept the validity of and pass on as "Truth" the salvation/damnation meme.
All this makes for very interesting socio-historical inquiry. What makes it even more interesting is that you will have relatively educated people who adhere to this rather hollow meme-scape without questioning the details.
The question for debate would be the validity of approaching religion as a social meme. Are the doctrines of Abrahamism more than a interesting effort at priest-based social control? And especially in light of the huge profit available in religion, is religion-as-meme as social control as business merely a successful cultural marketing formula which predates the modern study of marketing?
