“People in science fiction flicks always seemed to know useful things about the places time travel took them. But what if the time traveler had been only an average history student? What then?”

“She used her heart to love him, not her head, not her words and not her thoughts or ideas or feelings or any other vehicle or object or device people use to deliver love or love-like things. She used her heart, as a physical transmitter of love, and what came out of it was no more voluntary than gravity or time or time travel or the laws of fictional science itself.”

“That's just how time travel looks like to the untrained eye. The reason why there aren't more travelers is that your average physicist refuses to be eaten by a giraffe in the name of science.”

“Science fiction is the most important literature in the history of the world, because it's the history of ideas, the history of our civilization birthing itself. ...Science fiction is central to everything we've ever done, and people who make fun of science fiction writers don't know what they're talking about.”

“Most science fiction seemed to be written for people who already liked science fiction; I wanted to write stories for anyone, anywhere, living at any time in the history of the world.”

“For the first time, I had been struck by the excitement of the traveler who looks history in her subtle face.”
