New Atheism, also called evangelical atheism and militant atheism, is a term coined by journalists to describe the positions promoted by atheists of the twenty-first century. This modern-day atheism and secularism is advanced by critics of religion, a group of modern atheist thinkers and writers who advocate the view that superstition, religion and irrationalism should not simply be tolerated but should be countered, criticized, and exposed by rational argument wherever their influence arises in government, education and politics.
New Atheism lends itself to and often overlaps with secular humanism and antitheism, particularly in its criticism of what many New Atheists regard as the indoctrination of children and the perpetuation of ideologies founded on belief in the supernatural.
The Harvard botanist Asa Gray, a believing Christian and one of the first supporters of Charles Darwin's theory of evolution, commented in 1868 that the more worldly Darwinists in England had "the English-materialistic-positivistic line of thought". Darwin's supporter Thomas Huxley was openly skeptical, as the biographer Janet Browne describes:
Huxley was rampaging on miracles and the existence of the soul. A few months later, he was to coin the word "agnostic" to describe his own position as neither a believer nor a disbeliever, but one who considered himself free to inquire rationally into the basis of knowledge, a philosopher of pure reason [...] The term fitted him well [...] and it caught the attention of the other free thinking, rational doubters in Huxley's ambit, and came to signify a particularly active form of scientific rationalism during the final decades of the 19th century. [...] In his hands, agnosticism became as doctrinaire as anything else--a religion of skepticism. Huxley used it as a creed that would place him on a higher moral plane than even bishops and archbishops. All the evidence would nevertheless suggest that Huxley was sincere in his rejection of the charge of outright atheism against himself. He refused to be "a liar". To inquire rigorously into the spiritual domain, he asserted, was a more elevated undertaking than slavishly to believe or disbelieve. "A deep sense of religion is compatible with the entire absence of theology," he had told [Anglican clergyman] Charles Kingsley back in 1860. "Pope Huxley", the [magazine] Spectator dubbed him. The label stuck." —Janet Browne
