This volume brings together Gramsci's writings on religion, education, science, philosophy and economic theory. The theme that links these writings is the investigation of ideology at its different levels, and the structures which embody and reproduce it. Concepts such as subalternity and corporate consciousness, hegemony and the building of a counter-hegemony necessary for the formation of a new historical bloc, thus recur throughout the book. They complement some of the more overtly political writing published in the 1971 selection from the Notebooks .
