The Little Prince is a story that starts on such a low note that its almost childlike in its innocence, a quality maintained throughout its length. However, it intermittently raises questions about how a child perceives the world differently than a grown-up, having a completely different weltanschauung. The Little Prince remains relevant even after seven decades of its publication.
Maybe the age at which its read matters a lot. Maybe it is best suited for the age at which we slowly leave childhood behind but are not yet grown-ups. This limbo is a place where this story would make the most sense. But then, maybe all should read it, even the grown-ups. For although the inner child might be in hibernation, I’d like to think, nay believe that the kid is still alive in every grown-up.
