Nihilism and/or community. The European Question. The gift of the in-common. Touching on different themes and authors, the papers presented here probe the prolificness that the terms sacred and community could have – if subtracted from the game of reactive nihilism – in checking the violence of the diverse political and religious ideologies that the West administers. An escape opens in the implementation of critical thinking and ethical behaviour that involves the "sacrifice" of thought and of the thinking subject. The disputing of all the semantics of the logic of the recognition and the convenience that regulate life in advanced democracies.
