Reformed theologian Cornelius Van Til systematically analyzes the essential equivalence of thought in the arminiun view of salavation and the world’s view of the autonomy of man. He further argues that if humans are indeed “autonomous,” as existentialism teaches, then our choices are an illusion because we are enslaved to chance and will ultimately fall into despair. Van Til argues that the presupposition of ultimate truth in God alone is not just preferrable but necessary for any cogent understanding of reality. Without God, he writes, there is no basis for reason. This preeminent book on presuppositionalism is a must read for anyone interested in Christian apologetics.
