Strong atheism

Strong atheism or positive atheism is the lack of belief in any gods with the strong conviction that no gods exist.

Strong atheism is in contrast to weak atheism, in which the atheist does not believe in any particular gods but does not deny the possibility of their existence, and theism, in which the theist asserts that there is at least one god of some kind. The terms atheist and atheism are often used to indicate "strong atheism", though it also includes weak atheism in some contexts.
