The Myth of the Forbidden Fruit as Allegory on The Limits of Human Knowledge.
The history of science points out to the fact that all theories are born to be surmonted by yet to come better ones. Notwithstanding this, paradigmatic developments stay for us as truth as if ultimate, absolute ones.
What a fake news! We are allowed to infere that in a coming future, impossible to know how far from now, even Einstein's great theoretical achievements will sound as a rough approximation of a deeper insight on Physics.
Might this unreachable character of ultimate, absolute truths be the deepest meaning of the genesis myth of the forbidden fruit?
