Why don't we learn? Why don't we let go ?

What I came to realize is that we have failed before and we are still not learning from our mistakes. “gold, were produced. War sprang up, using both as weapons; the guest was not safe in his friend’s house; and sons-in-law and fathers-in-law, brothers and sisters, husbands and wives, could not trust one another. Sons wished their fathers dead, that they might come to the inheritance; family love lay prostrate. The earth was wet with slaughter, and the gods abandoned it, one by one, till Astræa alone was left, and finally she also took her departure.” [P10]
“Deucalion, and his wife Pyrrha, of the race of Prometheus, found refuge—he a just man, and she a faithful worshipper of the gods. Jupiter, when he saw none left alive but this pair, and remembered their harmless lives and pious demeanor, ordered the north winds to drive away the clouds, and disclose the skies to earth, and earth to the skies. Neptune also directed Triton to blow on his shell, and sound a retreat to the waters. The waters obeyed, and the sea returned to its shores, and the rivers to their channels.” [P12]In the terms of Ishmael we can consider these two Leavers, now that they worship and are faithful to the gods they get to live and they create a new civilization that are to become Leavers. Apparently this new civilization as done the same mistakes as the previous and it’s because no one is here to tell us our errors.
Are we one day Going to learn from our Mistakes?
