-: One day soon,
man is going to be able to harness incredible energies,
maybe even the atom,
energies that could ultimately hurl us to other worlds,
and the men that reach out into space
will be able to find ways
to feed the hungry millions of the world
and to cure their diseases.
They will be able to find a way
to give each man hope and a common future.
And those are the days worth living for.
You see the same things that I do.
We speak the same language.
-: The very same.

Spock: Edith Keeler, founder of the peace movement.
-: But she was right. Peace was the way.
-: She was right, but at the wrong time.
While peace negotiations dragged on,
Germany had time to complete its heavy water experiments.
With the A-bomb, and with their V-2 rockets to carry them,
Germany captured the world.
-: No.
-: All this, because McCoy came back
and somehow kept her from dying in a street accident
as she was meant to.
-: How did she die?
What day?
-: I can estimate general happenings from these images,
but I can't trace down
precise actions at exact moments, Captain.
I'm sorry.
-: Spock,
I believe
I'm in love with Edith Keeler.
-: Jim, Edith Keeler must die.
