Stanford University's Dictionary of Philosophy which includes, "‘Atheism’ means the negation of theism, the denial of the existence of God."
This makes no sense at all.
If theism is a belief in the existence of god or gods then its negation isn't 'denial' but a lack of belief.
As has been said a number of times before, there are two ways of looking at the negation of theism, i.e. "athei-ism" and "a-theism", i.e. the belief that there is no God/gods and a lack of belief that there are is a God/gods respectively, i.e. strong atheism and weak atheism respectively. Different people and different groups use the term "atheism" differently. Hence the need sometimes for clarification.
Alien - is your 'aThorism', the denial of the existence of Thor, or a lack of belief in the existence of Thor.
Both.
I suspect you might bristle at the notion that you were denying the existence of Thor and probably see that as a biased and pejorative definition.
What a very silly statement.
So Thorism is a belief in the existence of Thor. AThorism is a lack of belief in the existence of Thor.
If used as a parallel with atheism, there is both strong and weak athorism.
Just as theism is a belief in the existence of god or gods and atheism is a lack of belief in the existence of god or gods.
Is that meant to follow on as a result of what you wrote above, because it does not. There are two distinct meanings of "atheism" in use in English. I gave links to 4 non-Christian sites which explain the difference meanings.
Why are you lot so het up about it?
