Final answer:
The texts provided do not contain the reasons why Nausicaa believes Odysseus has no hostile intent in Phaeacia. In Homer's Odyssey, Nausicaa's belief could be based on the cultural practice of Xenia and possibly divine influence according to the narrative.
Step-by-step explanation:
The reason Nausicaa believes that Odysseus cannot come to Phaeacia with hostile intent is not explicitly detailed in the provided reference texts. Moreover, the excerpts provided seem to be from a variety of sources, several of which do not pertain to the Homeric poems. In the context of Homer's Odyssey, however, it's generally understood that Nausicaa, as a character, might hold the belief that Odysseus wouldn't harbor hostile intentions upon arrival in Phaeacia due to a combination of her own hospitality, the cultural expectations of Xenia (guest-friendship), and possibly divine influence suggesting the presence of a guest to be treated with respect. Additional information from the Odyssey would be required to provide a specific answer to this question.
