Friendship and Loyalty
Humans need friendship and good relationships with others.
When Crusoe runs away to London, he makes friends with
a ship’s captain who grows to like and trust him. He teaches
Crusoe mathematics and navigation until Crusoe becomes a good sailor.
Crusoe is a friendly and sociable person. The captain invites
Crusoe to go with him to Guinea, thus starting Crusoe’s involvement
in business and sailing. Crusoe also makes many friends while farming in Brazil.
When Crusoe gets shipwrecked on the island, he is desolate
and miserable. Deprived of human company, he finds comfort
and companionship with two dogs he rescues from the shipwreck,
the parrot and the cats.
During his twenty-fifth year on the island, he manages to
save a savage from a group of cannibals who land on the island.
This man is so grateful that he wants to be Crusoe’s slave.
However, Crusoe prefers him to be a friend. Crusoe teaches
him to eat animal flesh, speak English and share his religious beliefs.
Friday, as Crusoe calls him, becomes his faithful companion and friend.
Crusoe also becomes a friend to the Spanish and English mutineers
who were left on the island. He solves their disputes
and helps them to form friendships with each other.
