Oh bother, the question was just asked and people are already comparing “death toll” numbers.
Folks, with all do respect (be you atheist or Christian or whatever) - can we get any more cliche than this?
Eh, let’s begin shall we.
1.) Its Incoherent to talk about “Atheist morality” as it is just as incoherent to talk about “Theist morality.”
Explanation: People are confusing categories here. By themselves, atheism and theism hold no particular positive (not as in good, but affirmitive ones) doctrines associated with the belief or disbelief in the existence of a deity.
2.) However - the belief in either one can be attached to a set of doctrines.
Which is why its possible to speak of “Christian morality” or if we get more specific “Catholic Morality.”
In terms of those holding an atheistic standpoint - we avail ourselves of other options, normally manifestations of specific philosophical or political ideologies.
Read as: Atheism is a COMPONENT (a piece, a part, a segment) of a world view. NOT AN TOTALISTIC WORLDVIEW STANDING BY ITSELF.
Ex. Its possible to say all Communists are Atheists, its not true however to indulge in the reverse: all Atheists are Communists.**
**Some wise guy will point out the fact that there were in fact Communist Russian Orthodox and Daoist Chinese Communist officers thereby invalidating what i just said. Please bear with me - i’m only trying to make a statement for the general case.
What are some of the typical options? Well, it depends on a variety of criteria:
1.) Is the orientation of the atheist toward something individualistic? Or societal?
2.) Is the atheist attempting to reground morality in some absolute basis? Or is he/she comfortable with simply accepting the standard codes of conduct mandated by the society he/she is in?
3.) Is the atheist the type of person who needs a “group” of some sort? Here i’m not talking about friends or companions, but does the person feel the need to belong to some sort of organization that expresses views they hold dear?
And from those 3 questions you’ll get a variety responses ranging from some sort existential personalistic morality that is confined only to a single person (the thinker) or something far more brutal like the Totalitarian manifestations of Communism.
