“Knowing that you don’t know is the first and most essential step to knowing, you know?”
Claire Keen (Michelle Williams) in “Synecdoche, New York,” written and directed by Charlie Kaufman.
[From summary at imdb.com: “A theatre director struggles with his work, and the women in his life, as he creates a life-size replica of New York City inside a warehouse as part of his new play.”]
Kaufman may have been inspired for that line by Mark Twain: Among his many wise and witty observations on being human, Twain commented about some qualities of our thinking:
“What gets us into trouble is not what we don’t know. It’s what we know for sure that just ain’t so.”
Belief change author Morty Lefkoe addresses the nature of self-limiting beliefs and how to overcome them in programs of The Lefkoe Insitute.
In his article What You Don’t Know You Don’t Know, he explains,
“There are things you don’t know that you don’t know. And that fact, perhaps more than any other single thing, is keeping you from having the best life you could possibly have.
“When people know they don’t know something and they want to know about that something, they learn about it. You can search on Google to find out where to get help. You can ask friends what they did. You can read books and take courses. Etc.
“But far too many people don’t even realize that there is anything wrong. If you don’t know that there is something better in life and that you can achieve it, then you will not even search for it.”
