The definition for atheism that we use, put simply, says that atheism is the lack of a god-belief, the absence of theism, to whatever degree and for whatever reason. The one thing that all atheists have in common, according to this definition, is that they are not theists. One either believes one or more of the various claims for the existence of a god or gods (is a theist) or one does not believe any of those claims (is an atheist).
This, our working definition for the meaning of the words atheism and atheist, is known as the weak definition for the word atheism. We will cover several aspects of this definition during this discussion.
To assume that atheism involves more than the absence of theism is an error. Atheists are not necessarily Communists [3] (though some are). Atheists are not necessarily immoral or "wicked" [4] (though some are). Atheists do not necessarily assert that "no gods exist" (though some do). Atheism is but one component of an atheist's larger philosophical outlook and can influence that outlook, but atheism is never itself that primary outlook.
