Really? Which ones?
The ones by TJ for sure. I’m pretty sure the Abbey quote is bogus too. A little checking is in order from time to time.
So many quotes just get collected and copied and pasted that they take on lives of their own. Folks make up a great quote, and to give it cred, they assign it to a founding father. Then the bogus quotes are copied over and over.
I almost used what turned out to be a bogus quote on treason supposedly by Cicero in one of my books, but I checked and it was bogus. You have to go to primary sources like this UVA site to sort out the wheat from the chaff. Somebody even sent me his new novel, and it had bogus TJ quotes sprinkled throughout. Yikes.
