Gordon Haddon Clark (August 31, 1902-April 9, 1985) was an American philosopher and Calvinist theologian. He, like Cornelius Van Til (with whom he had many bitter disputes over philosophical matters related to their shared faith), was a primary advocate for the idea of presuppositional apologetics. He was chairman of the Philosophy Department at Butler University for 28 years.
Clark was raised as a Christian, and studied Calvinist thought from a young age. In 1924, he graduated from the University of Pennsylvania with a bachelor's degree and earned his doctoral degree from the same institution in 1929. He immediately took a teaching job there, before accepting a professorship in philosophy at Wheaton College in 1936. Clark was an expert in ancient philosophy and was noted for his rigor in defending Platonic realism against all forms of empiricism, in arguing that all truth is propositional, and in applying the laws of logic.
In 1944, Clark left Wheaton and was ordained a minister in the Orthodox Presbyterian Church, and he shortly thereafter accepted a position as professor at Butler University. In the years that followed, Clark would change denominations twice: first to the United Presbyterian Church of North America in 1948 and then to the Reformed Presbyterian Church of North America, General Synod in 1957. Clark was there instrumental in arranging a merger with another Presybterian denomination to form the Reformed Presbyterian Church, Evangelical Synod in 1965.
In 1974, Clark left Butler and taught at several institutions, including Covenant College in Lookout Mountain, Georgia, Sangre de Cristo Seminary in Westcliffe, Colorado, and the Reformed Episcopal Seminary in Philadelphia. After his death in 1985, his funeral services were held in Westcliffe, Colorado, where his body is interred.
Clark was a prolific author who wrote around forty books ranging from texts on ancient and contemporary philosophy to volumes on individual Christian doctrines to essays on education and politics to commentaries for laymen on the epistles of the New Testament. Some of his books are:
