Peter Singer, atheist, author and Princeton professor, who is considered the world’s leading ethicist, joins us for an illuminating discussion on his book, “The Most Good You Can Do: How Effective Altruism Is Changing Ideas About Living Ethically,” and his newest book, “Ethics in the Real World.” We  celebrate FFRF's winter solstice “equal time” displays now up in the Wisconsin State Capitol and Daley Plaza (in conjunction with our Chicago chapter), and report on a state/church victory to remove an unconstitutional nativity display in Michigan. In honor of the 120th anniversary of the birth of lyricist Ira Gershwin, we play Ira’s irreverent classic about the bible, "It Ain’t Necessarily So.”
