Chapter 5: Four Dimensions

The fact that the Tralfamadorians can see in four dimensions is truly amazing. While Billy is displayed in the zoo on Tralfamadore, he gains further information on what is in the fourth dimension, that he and all other Earthlings cannot see. He is told, "... their flying -saucer crews had identified no fewer than seven sexes on Earth, each essential to reproduction... ... active only in the fourth dimension" (Pg 114). He is again baffled by such findings, for he has no idea what the five have to do with the making of life for humans.
