Is there a superior will? How did the idea of a superior will enter into human thought? I think our proclivity in abstracting fresh ideas from the similarity of patterns, experiences, and other things is well known. In such instances what really happens is that we derive information from things that are independent of the things itself. I think the idea about a greater will too, originated in such way, that is, out of our interactions with fellow beings, both living and nonliving.
Humans, by closely observing natural events of births and deaths of living things would have acquired greater insights into life. They would have been struck by the fact that almost all things happen in sequence with some other thing. Which could have laid the foundation for a vast area of spiritual search, probably because, the instances where an obvious connection could be found with something real might have been few and far. Remember, people only had certain rudimentary ideas of the material world and it's composition, the prime one being the preponderance of cause and effect. And they would not have been successful in identifying a material cause for every effect, which could have better responded by the spiritual.
Now that the recent progress in science, notably those related to quantum theory, is suggesting a change to our, rather solid ideas of cause and effect, shouldn't we rethink the notions of a superior will?
