Narrator: Now the rockets come like beating drums. Like silver locusts swarming through the emptiness of space. And from the rockets come men to beat the strange world into a shape that is familiar to the eye. They come to find something or leave something or get something. To dig up something or bury something or leave something alone. To bludgeon away the strangeness.
Father Peregrine: And Lord, we have come to a new land. We shall need new eyes. We shall hear new sounds and needs new ears. And there will be new sins, which we ask the gift of purer and firmer hearts. Amen.
Father Stone: But Father, you are risking the entire expeditionary mission just--just so these--these inhuman...
Father Peregrine: Can't you recognize the human in the inhuman?
Father Stone: I would rather recognize the inhuman in the human.
Narrator: Wilder's mind is a confusion of troubled thoughts. Thoughts about the dead Martian who might have taught them something of the planet they were living on, thoughts of the planet they had left behind, the world about to face its final war.
Ruth: If what you say is true, then we'll be cut off. Isolated. Forgotten.
Wilder: There may be no one left on Earth to forget us.
Changes from the short stories:
* LaFarge's name is changed to Leif.
* Leif's son in the short story is Tom, and isn't a member of a previous expedition.
