The way one moves from the state of childhood to that of adulthood in the course of puberty has evolved very much throughout history. The body’s physiological changes have most often been correlated with the subject’s statutory and juridical change. One must observe that this is no longer the case and that, since its creation in the middle of the 19th century, adolescence keeps lengthening, to the detriment of the latency phase before it and of the accession to maturity after it. The difficulties this situation causes for adolescents should incite us to question it and suggest that the age of majority be lowered.
