*sniggers*
My 'atheism' is simply that there's no description of the known universe and my place in it that hasn't been best described by the observable. Empiricism. 'Best' meaning the most accurate in action, most in accordance with how things appear, most beautiful in aesthetic and most satisfying in totality.
That's not what I 'believe', because there's no jump from what I can verify.
Atheism is what I 'accept'.
(Technically agnosticism, but in practise i live without a deity. Atheist.)
PEARList? more like LIORLOPEan Limited Induction Of Reasoned Logic Over Physical Evidence.
Not so snappy.
