atheism

This term describes a specific philosophical position regarding the existence of deities. It ranges from a passive lack of belief to an active, reasoned denial of the divine. While often grouped with agnosticism, it differs by asserting a lack of belief rather than a claim of unknowability. As an uncountable noun, it refers to a conceptual state or a belief system. It does not take a plural form and cannot be counted as individual units; instead, it is treated as a singular mass noun representing a worldview.
