Here's what I know for sure

/

There are three depths of knowing.

  1. Hearsay: You’ve heard of the president. You’ve heard of Mt. Everest.

  2. Introduction: You’ve been introduced to the president. You’ve visited Mt. Everest.

  3. Intimately: You’re a good friend of the president. You’ve climbed Mt. Everest.

Understanding comes when you wrestle with these questions:

  1. What is the surest thing to you? 

  2. What would be the most impossible thing to doubt?
