- Margarita Levin does not admit to seeing many of the difficulties with the story, and she is excessively phlegmatic about the arrival ex nihilo of a machine containing one eccentric human being and the remains of another. She also swallows rather uncritically the distinction between personal and external time. I think it is better to regard these alleged time-travellings as cases when whole cross-sections in the life of a human being, mental and physical, have got displaced (though this does not explain the travelling part, and David Lewis dispenses with it).
- But Mrs. Levin's views are the most level headed and carefully logical and, though her diagram is a bit inelegant, she is the only competitor except Miss Denruyter to have worked everything out correctly – better than I had myself in fact, for I had not realised that Jocasta, poor woman, could commit incest by only one act of sexual intercourse2.
- Since two competitors have accused me of sexism3, one overtly and one by implication, may I point out that both the winner and one of the runners up are women?

- If you were to define 'incest' as having sexual intercourse with a person who was the product of your own previous act of sexual intercourse, then Jocasta would, so to speak, have committed a logically impossible crime.
