Among savages incapable of retaining collectively learned experience, a perpetual infancy results. I can no longer figure out these days whether I’m reading history or current events. [Note to self: If it’s on the Kindle, it’s a history book. If it’s on the web browser on my laptop, it’s currently happening.]

Berlin, 4-May-27:
“Goebbels spoke again at the Veteran’s Association House. ‘A fresh heckler was thrown out into the fresh air,’ he noted laconically in his diary. … Somebody had indeed heckled Goebbels during his speech and on a signal from the Gauleiter had been seized by a horde of SA men, brutally manhandled, and thrown down the stairs. A journalist from the Scherl publishing house who was discovered in the hall was subjected to the same treatment. …”

Columbus, OH, 21-Nov-15:
“Then, when Mr. Trump began talking about surveillance of refugees, the college-age couple standing in front of the students began chanting, “Hating Muslims helps ISIS.” The students were caught off guard, but after a moment of uncertainty, some of them joined in.
“Mr. Hopkins [a Trump supporter at the rally] leaned over and screamed, “Shut up!”
“Mr. Trump stopped his remarks and looked toward the commotion with disgust. “Two people, two people,” he said dismissively of the couple, as the crowd started booing and the people around them began shouting. “So sad,” Mr. Trump said. “Yeah, you can get ’em the hell out.”
“The crowd erupted in triumph as the protesters and students turned to leave. “Get out of here!” Mr. Hopkins shouted, shoving one of the two protesters in the back on his way out.
“One of the high school girls said afterward that as they exited, people in the crowd had asked them, “If you don’t love America, why don’t you just leave?” and that a man had told her that if she had not been filming on her phone, he would have slapped her.
“She and another student said they had heard an epithet for black people hurled their way.
“After Mr. Trump wrapped up his speech and “We’re Not Gonna Take It” blasted on the speakers, Mr. Hopkins rushed to the stage to get a picture of Mr. Trump.
“Asked what he thought of the rally, he said: “It’s like a movement! And he’s a man of action.”
“And the protesters? “Very rude.””

“Progress, far from consisting in change, depends on retentiveness. When change is absolute there remains no being to improve and no direction is set for possible improvement: and when experience is not retained, as among savages, infancy is perpetual. Those who cannot remember the past are condemned to repeat it.”
—_The Life of Reason_ (1905-06), George Santayana

I need add nothing to all that.
