This chapter delves into Ivan Illich’s provocative call to deschool society, questioning why his radical ideas are often overlooked and forgotten. Illich's critique targeted the educational institution itself, viewing it as a root cause of societal issues rather than merely a symptom of broader systemic problems. His refusal to blame external forces like capitalism or government, and instead, point directly at schooling and the teaching profession, struck a nerve and led to his marginalization. The chapter explores Illich’s influence from the social movements of the 1960s and 70 s, his collaboration with contemporaries like Everett Reimer, and the reception of his work compared to similar critiques. It highlights Illich’s unique insights into the educational system's role in perpetuating social inequalities and the hidden curriculum. The chapter also discusses the ongoing relevance of Illich’s ideas in the context of modern educational tools and technologies, questioning whether contemporary advancements can align with his vision of conviviality.
