Sociology has accustomed us to a critical reading of taste. A reflexive analysis of amateurs' activity allows for a point of view that is more attentive to how amateurs reveal taste to themselves. They do not 'believe'? in the taste of things; on the contrary, they have to enable themselves to experience it. Based on various case studies (rock climbing, wine, music) the author develops a pragmatist approach to taste as an activity and work on attachments; it is seen as a collective technique to make oneself sensitive to things, to one's body, to oneself and to situations. This also means putting reflexivity on the side of the amateurs and not only on that of sociologists concerned not to bias their analyses.
