Maria Gelpí writes in her introductory essay that “The artist feels the emergence of his action as a debt to the past and sees in aesthetics a mechanism of compensation”, which, in the case of this book, is a necessary principle. Francesc Torres (Barcelona, 1948) has questioned in his work an ideological status quo in which contemporary displacements leave the idea of communism out of play, but not Marxism as a philosophy, since “the promise it entails is still valid and necessary”. The reader has in his hands a book of great significance as an object and as an analysis of history, the continuing failure of utopias for Benjamin.
