The little prince in the story The Little Prince is searching. He doesn't completely understand what he is searching for, so he is open to learning from everyone and everything he encounters. The main problem in the story is his search for understanding - understanding of relationships, of the reasons why people act as they do, of how to learn to love and to trust and to care for the important parts of our lives. As he has brief encounters with many different minor characters through the book, he sees different aspects of life and makes observations about how to relate and react to those situations. In that learning process, the little prince gains the knowledge he was seeking. As the fox confirms to him at the end of the story, "It is only with the heart that one can see rightly; what is essential is invisible to the eye." The solution is love.
