Reviewing the debate on the relationship between young people, politics and political participation, it shows that a significant portion of young people are involved in more social forms of participation, rather than with political ones, because their references to political values and ideologies, as well as their trust in political actors, are weak. But, in parallel, it also challenges the hypothesis that the various ways in which young people are present in the political sphere can be considered simply as forms of political participation. Presenting the results of research on young activists from radical-left groups in Italy, the book shows that their involvement is only partly attributable to reasons of political intervention; instead, desires for experimentation and self-expression, as well as shared tastes and sensibilities that far exceed the boundaries of the political, characterize their participation, and are therefore a component of a broader, distinctive lifestyle. Based on these findings, the book calls for a rethinking of youth engagement, the reasons for which could be largely outside the field of politics.
