Can't upvote you enough for this. By the way, Feynman also knows the difference "between knowing the name of something and knowing something": http://www.youtube.com/watch?v=05WS0WN7zMQ
This. He really articulates clearly the difference between two ways of thinking. Thinking by really understanding then translating the thoughts into words and thinking by manipulating words.
While we're talking about Feynman, I think most people here could relate to his perspective on uninterrupted time, and the avoidance of administrative work: http://www.youtube.com/watch?v=Y08g3OXAA14&NR=1
The difference between knowing the name for something and knowing something, is probably most clearly elucidated when you ask someone who believes in a deity, what it is. The answer is invariably contains contradictory, unreconcilable aspects.
Found this great comment in underneath that particular YouTube video:
"He was just a curious kid in a grown up's body."
You've only got to watch Feynman's face as he's telling the story, or any story for that matter. His excitement and enthusiasm for the curiosities of life is infectious.
