Book excerpt: Play allows the fulfilment of one’s dreams, yet also teaches subjugation to the norms governing daily life. Furthermore, traditional forms of play, transmitted from one generation to another, guarantee a culture’s continuance and perpetuation in time. Contemporary forms of play integrate a populace, creating a specific community of laughter which places a high value on individuality and the ability to lead social games. Play invalidates social divisions, but also diversifies behaviours through the introduction of changes in the rules, depending on the age of those engaged. Furthermore, it adapts to the forms by which social reality is created, as well as that reality’s goals, which, in turn, impart sense and meaning to something which, of its own nature, seems deprived thereof.
