Jack Belicec: Stop trying to rationalize everything, will ya? Let's face it, we have a mystery on our hands!
Dr. Dan 'Danny' Kauffman: Sure you have. A real one! Whose body was it, and where is it now? A completely normal mystery. Whatever it is, it's well within the bounds of human experience, and I don't think you ought to make any more of it.
Dr. Miles J. Bennell: Look, I wouldn't if I hadn't looked in Becky's cellar! How do you explain away the body I saw there?
Dr. Dan 'Danny' Kauffman: I don't think you saw one there.
Dr. Miles J. Bennell: You don't think I saw one here, either?
Dr. Dan 'Danny' Kauffman: I know you did because three others saw it too.
Dr. Miles J. Bennell: But I dreamed up the second one?
Dr. Dan 'Danny' Kauffman: Doctors can have hallucinations too.

Wilma Lentz: There's no emotion. None. Just the pretense of it. The words, the gesture, the tone of voice, everything else is the same, but not the feeling.

Dr. Dan 'Danny' Kauffman: Love, desire, ambition, faith - without them, life's so simple, believe me.
Dr. Miles J. Bennell: I don't want any part of it.
Dr. Dan 'Danny' Kauffman: You're forgetting something, Miles.
Dr. Miles J. Bennell: What's that?

Dr. Miles J. Bennell: [having returned from finding that large numbers of pods are being grown in greenhouses, to Becky who, exhausetd, had fallen asleep in his absence] I've been afraid a lot of times in my life, but I didn't know the real meaning of fear until... until I had kissed Becky.

Dr. Miles J. Bennell: In my practice, I've seen how people have allowed their humanity to drain away. Only it happened slowly instead of all at once. They didn't seem to mind... All of us - a little bit - we harden our hearts, grow callous. Only when we have to fight to stay human do we realize how precious it is to us, how dear.
