“Traditional scientific method has always been at the very best 20-20 hindsight. It's good for seeing where you've been. It's good for testing the truth of what you think you know, but it can't tell you where you ought to go.”

“I've always been fascinated by maps and cartography. A map tells you where you've been, where you are, and where you're going -- in a sense it's three tenses in one.”

“You can only know where you're going if you know where you've been.”

“Goodnight, my angel
Time to close your eyes.
And save these questions for another day.
I think I know what you've been asking me.
I think you know what I've been trying to say.
I promised I would never leave you.
And you should always know
Wherever you may go
No matter where you are
I never will be far away.”

“You can't understand where someone's going unless you understand where they've been.”

“You look at where you're going and where you are and it never makes sense, but then you look back at where you've been and a pattern seems to emerge.”

“This has been a marathon election as you can tell with a record turnout and I think it has been good for politics and it has been good for London.”

“Would you tell me, please, which way I ought to go from here?"
"That depends a good deal on where you want to get to."
"I don't much care where –"
"Then it doesn't matter which way you go.”

“I can't go down there. They think I'm dead!
Oh, you've remembered that. Good for you.”

“You summarise your struggle for 20 years in 20 minutes and your child will remember 2 sentences, which is good.”
