Ivan Illich, Austrian priest and philosopher (d. 2002)
Ivan Dominic Illich (; 4 September 1926 – 2 December 2002) was a Roman Catholic priest, theologian, philosopher, and social critic. His 1971 book Deschooling Society criticises modern society's institutional approach to education, an approach that constrains learning to narrow situations in a fairly short period of the human lifespan. His 1975 book Medical Nemesis, importing to the sociology of medicine the concept of medical harm, argues that industrialised society widely impairs quality of life by overmedicalising life, pathologizing normal conditions, creating false dependency, and limiting other more healthful solutions. Illich called himself "an errant pilgrim."
