Atheism, as a philosophical view, is the position that either affirms the nonexistence of gods or rejects theism. When defined more broadly, atheism is the absence of belief in deities, alternatively called nontheism. Although atheism is often equated with irreligion, some religious philosophies, such as secular theology and some varieties of Buddhism such as Theravada, either do not include belief in a personal god as a tenet of the religion, or actively teach nontheism.
