The term puer aeternus is Latin for eternal boy. Carl Jung used the term in the exploration of the psychology of eternal youth and creative child within every person. It is an archetype, and like all archetypes, has both a positive and a negative side. It can bring the energy, beauty and creativity of childhood into adult life, or thwart self-realisation and doom us to both unrealistic adolescent fantasies and experiencing life as a prison. The puer is the man-child who refuses to grow up, take responsibility, and face life’s challenges, he expects other people, typically his parents, to solve all his problems. He tries to go as high as possible away from reality, ending up like Peter Pan, the boy who wouldn’t grow up, who lives in Neverland, a place where people cease to age and are eternally young. The puer aeternus is also known as the Peter Pan syndrome. This has become an increasingly common problem in our modern age. Those who find themselves unable to commit to work, to form satisfactory relationships, to commit to the discipline of education, to carry the weight of responsibility, or who feel that their life has become meaningless, will find the integration of the archetype of eternal youth invaluable in their life.
