Absence of theistic belief
Many atheists define their position as not accepting belief in gods without sufficient evidence.
What it is: In a more modest formulation, atheism can be defined as absence of belief in gods.
How the position understands it: In this reading, the burden of proof falls on whoever affirms divine existence, and suspension of belief is seen as intellectually legitimate.
Argumentative basis and context: This formulation has become common in contemporary debates, especially in contexts of public skepticism.
Debates and variations: Some philosophers prefer to reserve the term atheism for explicit negation, distinguishing it more sharply from agnosticism.
