Thanks once again, Barbara, for posting this. I would have missed it. I've already forwarded it to someone who I think will "get" it.
I considered sharing it on Facebook, but decided not to because I still have a few JW Facebook friends and I'd like to keep them. I have no doubt they would consider it persecution and "apostate lies." There are none so blind as those who will not see. (John Heywood, 1546)
The full saying is: "There are none so blind as those who will not see. The most deluded people are those who choose to ignore what they already know." (Random House Dictionary of Popular Proverbs and Sayings)
Sounds like Heywood defined a form of cognitive dissonance without ever having heard the term.
