atheism (āˈthē-ĭzˌəm) [key], denial of the existence of God or gods and of any supernatural existence, to be distinguished from agnosticism, which holds that the existence cannot be proved. The term atheism has been used as an accusation against all who attack established orthodoxy, as in the trial of Socrates. There were few avowed atheists from classical times until the 19th cent., when popular belief in a conflict between religion and science brought forth preachers of the gospel of atheism, such as Robert G. Ingersoll. There are today many individuals and groups professing atheism. The 20th cent. has seen many individuals and groups professing atheism, including Bertrand Russell and Madalyn Murry O'Hair.
