Games, festivals, folklore, a derivation of them, and artistic expression are manifestations of symbolic invention. To compare them is to bring out the differences in the order of the symbolic production and have, as a consequence, a differentiated perception of the way they function. It is also to put them into a perspective of filial relationship. In fact, a genealogy appears with the processes that regulate the passage from one to the other of these means of expression. Through the successive dissipation of structural stabilizations that are in turn play, festival and folklore, a generative order of complexity is established of which art, with its dynamics open to all expressive invention, is the end result. Finally, it is to discover at the end of the process the literary text, conceived as a work of art, surrounded by expression and preceded by it, appearing from then on according to one of the precepts of the theory of the text, as a production “of society and history” and as issuing from the social phenomenon in its entirety. “I am not only undertaking a study of a sociology of games,” wrote Roger Caillois. “My idea is to lay the foundations for a sociology beginning with games.” We would say of a sociology in which we would be permitted to glimpse the achievement of the task of explaining the entire social phenomenon itself.
