Right from wrong : why religion fails and reason succeeds
(Book)

Is there a non-religious method for discovering the elements of an objective morality? Yes, Smith argues--the worldview of humanism. Humanists apply reason, logic, and, evidence to all subjects. Smith's humanist approach to morality relies on discussion and debate among diverse participants as the best means to attain a moral code stripped of the biases of each individual, group, and society. The result is a hopeful portrait of how to build on the moral progress humans have achieved since the writing of religious scriptures.,Provided by publisher.
