If atheism is the lack of belief in gods, what is the term for the belief that there is no god?

When discussing the nuances of atheism, it is important to distinguish between different definitions and interpretations.

If atheism is defined broadly as the "lack of belief in gods," this is often referred to as implicit atheism or weak atheism. However, the term for the more specific and active belief that there is no god is commonly known as strong atheism or positive atheism.

• Strong atheism or positive atheism involves the explicit belief or assertion that there are no gods. This is a more active stance, where the individual not only lacks a belief in gods but also affirmatively believes that gods do not exist134.

In philosophical and academic contexts, this stronger form of atheism is often the standard definition used, where an atheist is defined as someone who maintains that there is no God, or that the sentence "God exists" expresses a false proposition34.
