Quentin Skinner's interpretation of Utopia is consistent with the speculation that Stephen Greenblatt made in The Swerve: How the World Became Modern. There, Greenblatt argued that More was under the Epicurean influence of Lucretius's On the Nature of Things and the people that live in Utopia were an example of how pleasure has become their guiding principle of life. Although Greenblatt acknowledged that More's insistence on the existence of an afterlife and punishment for people holding contrary views were inconsistent with the essentially materialist view of Epicureanism, Greenblatt contended that it was the minimum conditions for what the pious More would have considered as necessary to live a happy life.
Unlike many games, where different songs have different themes for each character or area, Wintory chose to base all of the pieces on one theme which stood for the player and their journey, with cello solos especially representing the player. Wintory describes the music as "like a big cello concerto where you are the soloist and all the rest of the instruments represent the world around you", though he describes it as not necessarily orchestral due to the inclusion of electronic aspects. The cello begins the game as "immersed in a sea of electronic sound", before first emerging on its own and then merging into a full orchestra, mirroring the player's journey to the mountain. While the game's art style is based on several different cultures, Wintory tried to remove any overt cultural influences from the music to make it "as universal and culture-less as possible". Tina Guo features as the cellist for the soundtrack. She is a close friend of Wintory and has since performed "Woven Variations" with him, an eight-minute orchestral variation on the Journey soundtrack. All of the non-electronic instruments in the soundtrack were recorded with a live orchestra.
The name Raphael, though, may have been chosen by More to remind his readers of the archangel Raphael who is mentioned in the Book of Tobit (3:17; 5:4, 16; 6:11, 14, 16, 18; also in chs. 7, 8, 9, 11, 12). In that book the angel guides Tobias and later cures his father of his blindness. While Hythlodaeus may suggest his words are not to be trusted, Raphael meaning (in Hebrew) "God has healed" suggests that Raphael may be opening the eyes of the reader to what is true. The suggestion that More may have agreed with the views of Raphael is given weight by the way he dressed; with "his cloak... hanging carelessly about him"; a style which Roger Ascham reports that More himself was wont to adopt. Furthermore, more recent criticism has questioned the reliability of both Gile's annotations and the character of "More" in the text itself. Claims that the book only subverts Utopia and Hythlodaeus are possibly oversimplistic.
