'Those who do not learn history are doomed to repeat it.'
The quote is most likely due to writer and philosopher George Santayana, and in its original form it read, "Those who cannot remember the past are condemned to repeat it."
Santayana was known for aphorisms, and for being a professor in philosophy at Harvard which he abandoned. Prior to that, Santayana attended Boston Latin School and Harvard College, where he studied under the philosophers William James and Josiah Royce.
Often the world has some understanding of Biblical truths. If you forget God’s truth, ignore God’s truth, deny God’s truth, then you will face God’s judgment. But, few will connect the dots and actually learn God’s truth.
2 Kings 22:8-13 And Hilkiah the high priest said to Shaphan the scribe, I have found the Book of the Law in the house of Jehovah. And Hilkiah gave the Book to Shaphan, and he read it.
And Shaphan the scribe came to the king and brought the king word again, and said, Your servants have gathered the silver that was found in the house, and have delivered it into the hand of the workers, who have the oversight of the house of Jehovah. And Shaphan the scribe showed the king, saying, Hilkiah the priest has delivered me a Book. And Shaphan read it before the king.
And it happened when the king had heard the Words of the Book of the Law, he tore his clothes. And the king commanded Hilkiah the priest, and Ahikam the son of Shaphan, and Achbor the son of Michaiah, and Shaphan the scribe, and Asahiah a servant of the king, saying,
Go inquire of Jehovah for me, and for the people, and for all Judah, concerning the Words of this Book which is found.
For great is the wrath of Jehovah which is kindled against us, because our fathers have not listened to the Words of this Book, to do according to all which is written concerning us.
What did Josiah do? He tore his clothes in fear of what had been read to him. What did Hilkiah do? He sent Shaphan to the king. What book had he been using? What doctrine had he been teaching? What god had he been serving?
Was Josiah the only one truly taking God seriously? It had been so long since the Word of God had been ignored, that no one even bothered to notice it missing!
So, Satan came into the Temple with his false, idolatrous worship and took over. He did this with the aid of the descendants of Aaron, who were the only ones that could be High Priests.
What did God think of all of this?
