For Marx by Louis Althusser
"For Marx" is a collection of essays that delve into the complexities of Marxist theory, aiming to rejuvenate and redefine Marxist philosophy in the context of the 20th century. The book critically examines existing interpretations of Marxism while introducing the concept of "theoretical practice." The author argues for the scientific rigor of Marxist thought and emphasizes the importance of ideology's role in political struggles. Through a structuralist approach, the work seeks to distance itself from humanist and economistic readings of Marxism, advocating for a return to the foundational texts and insisting on the revolutionary potential embedded in rigorous theoretical analysis.
