In this new text published in Pluto Press’ “Reading Gramsci Series”, Massimo Modonesi seeks to explore the theoretical genesis of three core concepts that make up the title of the book—namely, subalternity, antagonism and autonomy—and the problems that the usage of these pose for Marxist debates. The concepts in question, as first revealed in my review for Antipode online, are explicitly linked to the process of political subjectivation (or subject formation) in terms of the experiences of subordination, insubordination and emancipation. Each concept is also linked to a key author associated with its development. Antonio Gramsci’s writings are therefore explored in relation to subalternity; Antonio Negri’s in regards to antagonism; and those of Cornelius Castoriadis in connection with autonomy. Scholars of each respective thinker are likely to find merit in various individual chapters of the book as it traces in detail the development of their intellectual trajectories.
