Atheism, A Grim Position?

[robvalue]

If you are looking for "objective morality", that is what religions use, and it is terrible. It's a series of prescribed rules of what is and isn't moral. It's arbitrary, inflexible, unnatural and doesn't cover the grey area we spend our whole life in. Morality changes depending on context, and often many different moral considerations overlap. You may be choosing between the lesser of two or more evils. The only proper way to evaluate moral behaviour (moral as in the wellbeing of individuals and of society) is a benefit/harm analysis. This can never be objective, and is unlikely to ever be perfect, but we generally do a good job at it. We've evolved that way.

It sounds kind of like you're looking for a cosmic policeman or authority, but the fact is we police ourselves more than anyone else. We have a conscience which tells us when we are doing bad stuff, and it makes it harder for us if we ignore it.
