Despite the pluralism of contemporary American culture, the Judaeo-Christian legacy still has a great deal of influence on the popular imagination. Thus it is not surprising that in this context atheism has a slightly scandalous ring, and unbelief is often associated with the lack of morality and a meaningless existence. Distinguished philosopher and committed atheist Michael Martin sets out to refute such notions in this thorough defense of atheism as both a moral and a meaningful philosophy of life. Martin shows not only that objective morality and a purposeful life are possible without belief in God but also that the predominantly Christian worldview of American society is seriously flawed as the basis of morality and meaning.
