Puer aeternus

Puer aeternus (Latin for 'eternal boy'; female: puella aeterna; sometimes shortened to puer and puella) in mythology is a child-god who is eternally young. In the analytical psychology of Carl Jung, the term is used to describe an older person whose emotional life has remained at an adolescent level, which is also known as "Peter Pan syndrome", a more recent pop-psychology label. In Jung's conception, the puer typically leads a "provisional life" due to the fear of being caught in a situation from which it might not be possible to escape. The puer covets independence and freedom, opposes boundaries and limits and tends to find any restriction intolerable.^[1]
