Atheism is often considered to be a negative, dark and pessimistic belief which is characterized by a rejection of values and purpose and a fierce opposition to religion. This book sets out to dispel the myths that surround atheism and show how a life without religious belief can be positive, meaningful, and moral. It also confronts the failure of officially atheist states in the Twentieth Century. The book presents an intellectual case for atheism that rests as much upon positive arguments for its truth as on negative arguments against religion.
