The Everlasting Man is a Christian apologetics book written by G. K. Chesterton. It is, to some extent, a deliberate rebuttal of H. G. Wells' The Outline of History, disputing Wells' portrayals of human life and civilisation as a seamless development from animal life and of Jesus Christ as merely another charismatic figure. Chesterton detailed his own spiritual journey in Orthodoxy, but in this book he tries to illustrate the spiritual journey of humanity, or at least of Western civilisation.

G. K. Chesterton was an English writer, poet, philosopher, dramatist, journalist, orator, lay theologian, biographer, and literary and art critic. Chesterton is often referred to as the "prince of paradox". Chesterton is well known for his fictional priest-detective Father Brown, and for his reasoned apologetics.
