Isaiah 5:20
Woe to those who call evil good
and good evil,
who put darkness for light
and light for darkness,
who put bitter for sweet
and sweet for bitter.
I must note that I personally do not perceive that there can be a pure "atheism" insofar as man is by nature a religious creature (I mean an innately God-seeking being), and those who name themselves "atheist" are actually making of themselves the god and center of their universe around which all matter revolves and which all matter serves - as illogical as that is...Ozymandias comes to mind...
