Praise for The Moral Arc:

Ambitious... Mr. Shermer is a buoyant culture warrior-and an eloquent one, who believes that our better angels will continue to soar. The Moral Arc presents an impressive account of how far we have come. But it also reminds us that reason, for all its muscle, will need a lot of help to make our moral progress continue.-The Wall Street Journal

Michael Shermer [claims that] science...has helped to lay the moral groundwork for modern society, pointing the way to a more just and moral world...Bravo, I say.-Michio Kaku, theoretical physicist, author of the best seller The Future of the Mind, and Physics of the Future
