on what basis are morality and evil valid concepts in an atheistic universe? keep in mind, im not asking whether you act morally or not, but rather how you account for it.
You don't need an old book to know that killing, raping and stealing are wrong.
Morality isn't dependent on faith.
Each atheist is an individual unlike the next but the ones I know have a deep love for life and respect for it as well.
Our individual moralities are shaped by accumulated experiences, the laws of the law and our own levels of empathy.
Some people might think that with the absence of God there is no liability therefore someone would be more likely to give into whatever cruel desires they have but that is unfounded.
With the religious it sometimes seems that they can do whatever they want so long as they repent after.
i read a few of you say that the burden of proof is on the theist. how so?
You are the ones that make extraordinary claims and often settle on faith as an answer. Atheist actually have nothing to prove. You are the ones insisting there is a supernatural entity which created all life on this earth, made us in his image and also make many more outlandish claims depending on how deeply you believe and what you do believe.
When someone tells me the earth is no more than 6000 years old and dinosaurs didn't exist they better be prepared to back those claims up logically because I certainly have enough geological and archaeological facts to back up my side of things.
Also check this out in case you missed it.
some of you are trying to pass off that atheism is the "default position". how?
Not sure what you mean by default position, if you mean most likely right compared to opposing theories then yes.
According to this random site
http://www.adherents.com/Religions_By_Adherents.html there are over 20 major religions which have over 500 thousand adherents each.
Each of these view the world in different ways, make different claims to creation and most can be interpreted in a plethora of ways. Christianity itself has tens of thousands of diverging interpretations.
Also consider the hundred of thousands of religions and belief systems that have come and gone since the dawn of mankind.
As an atheist all I believe that all of these religions and belief systems say something about the times and the cultures that came up with them but in the end are all basically fantasy.
Just because your ancestors happened to be on the winning team doesn't make your belief system any more valid.
So when you have possibly millions of ways of interpreting the world versus one very down to earth proposition then I'd guess I could see why it might be the default for some.
