Out of the Silent Planet Themes
The main themes in Out of the Silent Planet are Christianity, racism, and friendship.
- Christianity: As an omniscient, omnipresent, yet invisible being, Oyarsa stands in for the Christian God, and the utopian nature of Malacandra represents Lewis's vision of the harmony and goodness of Christianity.
- Racism: The three Malacandran races all live in harmony. This harmony is contrasted with the discord on Earth, where the different races find themselves in frequent conflict.
- Friendship: Ransom's friendship with Hyoi allows him to become a part of Malacandran society in a way that the friendless Weston and Devine cannot, suggesting that friendship can bridge any divides.
