Miracles is the C.S. Lewis work that argues for the possibility of miracles against naturalism. The book was first published in 1947 and develops Lewis’s philosophical case for a supernatural dimension to reality.
Lewis distinguishes naturalism, the view that nature is all that exists, from supernaturalism, which allows for realities beyond the natural order. He argues that reason, consciousness, and human knowledge are difficult to explain if every thought is merely the product of nonrational physical processes. From that foundation, he defends the possibility that God can act within nature.
The book does not simply list biblical miracles. It first examines the philosophical assumptions used to reject miracles and then considers how natural and supernatural explanations relate. Lewis’s argument is part of his broader Christian apologetic writing.
Miracles is sometimes confused with The Problem of Pain, which focuses primarily on suffering, or Mere Christianity, which grew from wartime radio talks. Those books address related religious questions but are not the work centered on the philosophical defense of miracles.
