As in many works of literature, there is more than one main theme in Antoine de Saint-Exupéry's novella The Little Prince. The themes of this book all relate to the nature of being human. These themes are presented through the interactions of the aviator, the Little Prince, and other characters, who all present different perspectives on each of the various themes. Since several themes have already been mentioned within this topic, I'll add two more main themes here: growing up and adventure vs. familiarity.
One of The Little Prince's central themes examines the change from child to adult and the transformation that takes place between those two life phases. By the end of the novella, each of the characters, and especially the Little Prince, has changed in some way. While this change is a natural and expected transition, there is a sadness that accompanies the change. The Little Prince, for example, knows he cannot remain the same but with his growth gains knowledge that makes him sad yet wiser. Though the Little Prince at the end of the story has a greater understanding of the world, he also carries more sorrow.
Adventure vs. Familiarity
The Little Prince is written with a whimsical tone, and this tone is a reflection of a recurring theme throughout the work. The characters learn the value of keeping wonder and curiosity as they explore. This theme extends beyond simply decrying the dangers of narrow-mindedness. Rather, the theme suggests that it is valuable to actively explore and be curious instead of letting expectations and preconceived understanding dictate our actions.
