Hmmm she summed it nicely. Why isn't Knowledge isn't included for man in the heavens... I don't know about other faiths, but in Christianity goes further to not only does not give it as reward but have it as forbidden since the first couple were kicked out for eating from the tree of knowledge. Lesson =Seems God doesn't like for for mankind to think for themselves.
Reminds me as well of Greek mythology, where Prometheus was eternally punished for bringing fire from the gods, to man. If we take the story symbolically, then it's plausible to consider the light and warmth of fire to represent knowledge of sorts, since it then enabled civilization to develop among man. The parallel is striking, and we see this same theme of the theft of fire through mythologies the world over: from the Cherokee and the indigenous of the Pacific North West, to the Greeks and the Indians, to the Levant.

The gods, if any of them exist, really don't seem to like free thinkers; but then, no tyrant ever does.
