Beginning with an insightful study on the nature of man, Chesterton argues that the central character in history is Jesus Christ, the everlasting Man. No other explanation of the world fits the evidence. Exploding the stale formula of Christ as the pale product of human imagination, he triumphantly asserts the glory and unassailable logic of Christ as the God who, in the fullness of time, steps into his own creation. Displaying all of his brilliant synthesis and devastating irony, The Everlasting Man is perhaps Chesterton's best book. C. S. Lewis, who cited The Everlasting Man as one of the principal books in his conversion, said, "I read Chesterton's Everlasting Man and for the first time saw the whole Christian outline of history set out in a form that seemed to me to make sense."
