Atheists, conservative theists, and religious liberals often read the history of science in ways that support their own position. Atheists expect continual mutual support between science and nonbelief, conservatives emphasize theistic metaphysical foundations for science; and liberals find a historical development toward separate spheres for science and religion. The rise of science was more complicated than anticipated by any of these stories. Atheism and science have usually developed almost independently, with weak connections. Today, the naturalism of modern scientific descriptions of the world is consonant with an atheistic position. But even now, significant tensions between science and atheism remain.
