This volume analyses the philosophical nature of Gramsci’s Marxism and its Hegelian source, the radical critique of the economistic tradition and the original analyses of the role of superstructures, ideology, consciousness and subjectivity in the revolutionary process. It relates the central themes of Gramsci’s writings, such as hegemony, ‘historical blocs’, the role of intellectuals and political praxis, to the more peripheral ones, such as science, language, literature and art. The introduction includes a brief intellectual biography of Gramsci.
