Andrew Feenberg's 'The Philosophy of Praxis' offers a profound analysis of this pivotal concept in critical theory. The book meticulously traces the intellectual journey of praxis, starting from its foundational articulation in Karl Marx's thought, through György Lukács's seminal contributions, and culminating in its multifaceted interpretations by the influential thinkers of the Frankfurt School. Feenberg delves into how these key figures grappled with the relationship between theory and practice, the role of revolutionary action, and the critique of reification and instrumental reason in modern industrial society. This work provides an essential understanding of how the philosophy of praxis remains vital for comprehending social change, technological development, and the ongoing struggle for human emancipation in the modern world, offering a compelling narrative on the evolution and contemporary relevance of this core philosophical tradition.
