How we know right from wrong without God or religion

Do we really need an imaginary guy-in-the-sky to tell us what's right and wrong? Not anymore, says Skeptic Magazine's Michael Shermer.

Do we really need God or religion to tell us what's right and wrong? Michael Shermer, the publisher of Skeptic Magazine, says that this kind of celestial-spiritual guidance really isn't necessary. Or particularly effective. He makes a great case for being a moral realist — for example, studying past examples of war or slavery to learn morals from them — is much more effective than going back to mysticism like, say, The Bible, a fantastical book written by committee some 2,000 years ago and hardly updated since. Michael's new book is Heavens on Earth: The Scientific Search for the Afterlife, Immortality, and Utopia.
