The Enlightenment was an intellectual movement of the late 17th and 18th centuries that was a self-conscious move away from the Reformation's emphasis on faith and revelation. It was the mind of man that became the new standard.

"My own mind is my own church," wrote Thomas Paine in his Age of Reason (Part First, 1794), which was an attack on all religion that claimed to be authoritative and Christianity in particular. It is not without cause that Paine's title is sometimes used as a synonym for the Enlightenment. Its rationalism saw faith as a blind confidence, a belief in nothing, while Hebrews 11:3 tells us it is "through faith we understand..." The Christian must see faith in God's revelation as opening up understanding, as thinking God's thoughts after him, and rationalism as a restriction of thought to the narrow confines of human understanding. Reason is a gift of God, but we must not make more of it than it is. To see our reason as supreme is to see ourselves as supreme, and thereby repeat the sin of seeking to \"be as gods\" (Gen. 3:5).

The first three essays of this volume were published in a small booklet in 1960 as a tribute to the thought of Dr. Cornelius Van Til, titled Van Til. The last four essays were written some time later and are published here for the first time.
