Abstract : This thesis is based on fieldwork made in Colombia with young people. It proposes a new way to try and understand how values are passed down and the identification processes work. The emphasis is laid on the importance of " configurations ", interaction between the body and actual experience. The author borrows from Norbert Elias this term of " configuration " because it goes beyond the idea of a society independent from the individual, as well as that of an individual considered as a nucleus and independent from others. In this context, we understand that together, people form " concrete configurations" that cannot be analysed without taking into consideration the intention of those who act. In the first part, the author sums up the situation and regards the ¤crisis of values¤, He then analyzes the complex and varied processes of transmission. He underlines the main aspects that distinguish adolescence and youth that can help us understand the transmission processes during these periods of life. The second part studies theses processes and their characteristics, as well as successes and failures by comparing three different configurations: one in a college in town, one in a working class district and one in an Indian community. A chapter is devoted to transmission with the family. The third part consists in the analysis of characteristics required from the transmitter, the processes, transmission's means, and studies how the receiver integrates the transmitted values and makes them his own. Specific attention is given here to the place of the body and to the psycho-affective perception of the values.
