Ivan Illich was an Austrian philosopher, Catholic priest, and writer who criticized modern institutions and technologies. He was born in 1926 in Vienna and studied in several European cities before becoming a priest and moving to the US. Illich later left the priesthood and moved to Mexico, where he established an intercultural research center. He wrote several influential books critiquing issues like education, medicine, and technology. Illich argued that institutions often end up serving purposes opposite of their original intentions and advocated for more convivial and decentralized systems. He died in 2002 in Germany.
