Didn't think this quote to be something that Einstein would write. He usually didn't write in such an esoteric illogical way, so it made such little sense. It's possible that personal letters he wrote may have been misinterpreted. Yet I've found no real reference of this attribution to Einstein.
Was thinking of Thomas Cromwell, a bureaucrat, whose reforms enabled a lot more tax to be collected in England in the time of Henry VIII.
Seem to remember something about putting the king's name on things to get things done.
Then ,I am sure, there's a Churchill quote I used I since read that wasn't by Churchill.
John Lennon I have read quotes that weren't him.
So it's almost a popular thing.
Partly remembering a quote, then attributing it to a famour person at the time. So famous people get to be a lot wiser over time.
Then in earlier times, quotes attributed to the king as is word was law.
Just to get things done.
But I often think,that the king's enemies win the day with quote. As there is also a trend to undermine the intent of the cute through lampooning or whatever.
For example :
King Canute,surrounded by stupid people, takes them for a trip out to the sea, and attempts to give them an example of the limits of Kingly power.
Positioned on the beach,clearly demonstrating he can't control the tide.
See, I have limits, I'm a person. Now do you see?
So when they go home the story becomes "the idiot thinks he can control the sea"
I even got a link for you Misunderstood. Unprecedented.
King Canute and the tide - Wikipedia
Even though I suspect you knew the full story... Ish
