Title: Ivan Illich
Content:  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."

After ten years, critical analysis from the CIDOC of the institutional actions by the Church brought the organization into conflict with the Vatican. Unpopular with the local chapter of Opus Dei, Illich was called to Rome for questioning, due in part to a CIA report. While he was not convicted or punished by the Vatican, it was then that he decided to renounce active priesthood. In 1976, Illich, apparently concerned by the influx of formal academics and

Illich, who had been made a Monsignor at 33 himself resigned from the active priesthood in the late 1960s, but continued to identify as a priest and occasionally performed private masses. In the 1970s, Illich was popular among leftist intellectuals in France, his thesis having been discussed in particular by André Gorz.

Title: Ivan Illich
Content:  Ivan Dominic Illich was born on 4 September 1926 in Vienna, Austria, to Gian Pietro Ilic (Ivan Peter Illich) and Ellen Rose "Maexie" née Regenstreif-Ortlieb. His father was a civil engineer and a diplomat from a landed Catholic family of Dalmatia, with property in the city of Split and wine and olive oil estates on the island of Brač. His mother came from a Jewish family that had converted to Christianity from Germany and Austria-Hungary (Czernowitz, Bukowina). Ellen Illich was baptized Lutheran but converted to Catholicism upon marriage. Her father, Friedrich "Fritz" Regenstreif, was an industrialist who made his money in the lumber trade in Bosnia, to later settle in Vienna, where he built an art nouveau villa. Ellen Illich traveled to Vienna to be attended by the best doctors during birth. Ivan's father was not living in Central Europe at the time. When Ivan was three months old, he was taken along with his nurse to Split, Dalmatia (by then part of the Kingdom of Yugoslavia), to be shown to his paternal grandfather. There he was baptized on 1 December 1926. In 1929 twin boys, Alexander and Michael, were born in the family.

Illich looked askance at the liberal pity or conservative imperiousness that motivated the rising tide of global industrial development. He viewed such emissaries as a form of industrial hegemony and, as such, an act of "war on subsistence". He sought to teach missionaries dispatched by the Church not to impose their own cultural values.
