cool. a good ZING is needed around here from time to time.
The belief in the supernatural has led to progress... progress in thought. Progress in thought leads to "breakthroughs and innovations", whether that be a materialistic or conceptual advancement. The belief in the supernatural is an innate characteristic that spurs mankind to evolve, adapt, and change just as much as greed does.
I would have to ask you to explain this further. Seems to me, from a cursory review of history, that the unexplainable has always been the realm of the supernatural (whether every living thing had a "spirit" as anicent pagans believed. or there is one God like the Jews believed and then others followed).
Man's inability to understand has created the supernatural. For example, the question "What happens after death?" has led to more specualtion and creation of mythology than anything. And why? it is the ultimate unanaswerable question.
In ancient times, people who had seizures or something similar were "possessed by demons". Science has eliminated demons from the teachings of most medical books (except in Haitian Santeria practitioners

)
How about the nonsensical phrase "God works in mysterious ways?" WTF is that?
It is not merely the big 3 religions that have a stranglehold on the supernatural. Buddhists have supernaturalized karma (long before George Spellwin did) because karma is basically "chance" and chance cannot be explained scientifically. Hinduism - I don't know it that well, but it has about a billion adherents.
My general point is, the thought process spurred by the supernatural has always one of inventing answers to the unknown, rather than knowing it. How can this help?
I'd have to say the biggest problem today (and always) is ignorance. You mention that "almost all violations of human and property rights can be traced to a belief in the supernatural"; however, it is ultimately ignorance that leads to "problems".
OK, but the root cause of ignorance seems to be a subscription to a belief in the supernatural, which, as i stated (or tried to) above, precludes understanding.
