The Limits

"I don't know, and neither do you." 

"Neither do they." 

"But you don't know whether they do or don't know, and neither do I." 

"So what do we know?" 

"We know that we don't know. We also know that you think they don't know and I think they do know, but we don't know and can't know whether or not they do know, and this is all that we can know."
