Fringe, Season 1

Walter:
Consider this...What is mankind's oldest dream?

Astrid:
World Peace?

Walter:
Oh hardly. It's a social construct imposed by an awareness of our own mortality.

Astrid:
Should have gone with 'great taste, less filling' huh?

Walter:
What is the greatest desire of the weak, of the subjugated, of the man whose fire is stolen by an opponent whose only advantage is the luck of superior size?

Astrid:
We're stealing fire?

Peter:
I think we're cavemen in this story.

Walter:
Whose woman is wrenched away by brutality and force?

Peter:
Sexist cavemen at that.

Walter:
Simple. To kill with thought. To wish someone dead. To murder with the mind.

Peter:
Come on, that's ridiculous!

Walter:
You're right, I'm sure. Unless of course it happens again.
