In 2010, the Witherspoon Institute published a book of over 260 pages entitled The Social Costs of Pornography: A Reader, with a Foreword by Jean Bethke Elshstain and an Introduction by James R. Stoner and Donna M. Hughes. This article will present some of the extensive evidence provided by the Reader of current scientific studies to show that use of pornography causes terrible harms to millions of people today.
