Steven Pinker’s ad endorsing the Freedom From Religion Foundationad endorsing the Freedom From Religion Foundation will air nationally on “CBS Sunday Morning” three Sundays in a row, starting Mother’s Day, May 12.

The distinguished Harvard professor and best-selling author, who serves as FFRF’s first honorary president, urges viewers in the 30-second advertisement to join FFRF in its fight to prevent religion from creeping into U.S. government. Pinker’s newest book is Enlightenment Now: The Case for Reason, Science, Humanism and Progress.

The ad ran briefly in late March on CBS’ “The Late Show with Stephen Colbert.” This will be the first time an FFRF commercial has aired on “CBS Sunday Morning” (currently hosted by Jane Pauley) since FFRF’s ad featuring John F. Kennedy famously endorsing the separation of state and church.

“The world has become a better place, as reason has been overcoming superstition and tribalism. But the values of the Enlightenment are under attack,” warns Pinker in the current ad. “Please join me in supporting the Freedom From Religion Foundation to ensure that our government is driven not by religion, but by reason.”

The Freedom From Religion Foundation is delighted and honored to receive the affirmation of a leading global intellectual.

Pinker is one of the world’s premier intellects and cognitive psychologists, and serves as the Johnstone Family Professor of Psychology at Harvard University. He’s on the Time 100 list of the world’s “Most Influential People.” Among his other popular books are The Blank Slate, The Language Instinct and How the Mind Works.
