Recently, it has come to light that many scientists—scientists who don't believe in God--nevertheless claim to be "spiritual but not religious." Some in the secular movement have responded favorably to this new trend-one unfolding against the backdrop of an increasingly secular America, and a millennial generation that is also discarding traditional religion while extolling spiritual meaning.

Yet others are sharply opposed, calling secular "spirituality" little more than a semantic gambit, a misappropriation of misleading, faith-infused language.

In this week's show, we present two different takes on whether we should embrace, or discard, the concept of godless spirituality.

Our first guest, Adam Frank, is a nonbeliever with a deep respect for the domains of human spiritual endeavor who represents the pro-spirituality view. Frank is an assistant professor of astrophysics at the University of Rochester, where he studies the formation and evolution of stars. He's also a freelance writer for Discover and Astronomy magazines, a blogger at NPR's 13.7, and author of the book The Constant Fire: Beyond the Science vs. Religion Debate.

Our second guest, Tom Flynn, is a non-believer represents the anti-spirituality view. He's the executive director of the Council for Secular Humanism, editor of Free Inquiry magazine, director of Inquiry Media Productions, and director of the Robert G. Ingersoll Birthplace Museum, among many other accomplishments. He has written numerous books, both fictional and non fictional, including 1993's famed (and in-famed) The Trouble with Christmas.
