Nowadays, atheists define their position as “lack of a belief in God or gods”. This definition itself is idiotic. By defining their position as lack of belief, that means that bricks, dust motes, and people in comas are atheists.
If we add a reasonable clause to this, changing it to “Atheism is lack of a belief in God or gods, in an agent that is capable of such a belief.” we end up with a psychological property. Psychological properties are uninteresting for philosophical discussion. “I lack a belief in God.” Well, we do believe in God. So what? Do you hold that lack of belief to be rationally justified?
They claim this lack of belief doesn’t have any additional impact on other beliefs.
