Now now, don't discount the influence of superstition and it's evolved institution of religion when it comes to the development of human society. Before there was Love and Logic, these institutions invoked one of the strongest reasons to behave and organize society, penalty in the "afterlife" for your behavior while alive. Basically a form of fear you could not verify. Given that, for most developed societies today, there is no longer a reason for the parochial institutional control of faith [save to get off easy for bad/selfish behavior by a enunciating number of hail Mary's (or it's equivalent depending on religion) and a bit extra in the passed plate], you can't deny the affect in the early days that eventually drove us to here, the most dominant species on the planet (about 3x too dominate in numbers BTW, nature will correct that). For less developed societies, the cultural hangover persists.
