Quote context

[...]

- Here, would you care for a cigarette, Professor?

- No, thanks. I'm attached to my pipe.

- Professor, I read one of your books on the materialization of thought. You denied that it was possible, but the thought was intriguing. Yes, if it could be done, why, man could create power by thought.

- He could will a door to open. He could perform useful work without moving from this chair. Practically anything.

- I said it was impossible, didn't I?

- Is it? Perhaps with atomic power it could be done.

- Oh, please. I'm tired and sick. Stop badgering me, please.

- I will if you'll answer me a few questions.

- Jeff!

- I'm sorry, but I've got to go on.

- What were you doing in the cemetery tonight, professor? Were you, uh, looking for this?

- I didn't mean to shut you in, close the door on you. I was frightened when I heard you. I only wanted time to get away.

- I only realized later that you might be shut, trapped. I called Barbara, but...

- If she hadn't rescued me, I wouldn't be alive.
