Q: Atheist-GAF what comprises morality? Is moral truth objective or relative?
A: I think morality is relative. To me, it is very arrogant to think that one knows some universal truth about all possible life in the universe, even without having knowledge of the possible diversities and cultures out there. How can you say you know what is right and wrong for every living thing out there, without even knowing the first thing about what living things even exist?
Maybe this speaks to my personal philosophy more than what is necessarily accurate, but I always err on the side of ignorance. That is to say, I will always assume there is more to know about a subject; that there is a greater subtlety and depth to all things than I have yet grasped.
You might point out that the existence of a universal, objective morality doesn't mean I have to know what that morality is in detail. I can remain ignorant of its detail but still believe it exists. I guess a better answer is that, if morality is what is 'right' and 'wrong', then given all the diversity of life, culture, circumstances, etc, the only possible accurate morality I can imagine would be either pointlessly vague or pointlessly complex. "Do good, depending on the situation." or "In this culture, on this planet, on these days of the week, in this situation, the right thing to do is statistically X. Subject to change."
Morality, I think, is a flawed human construct. Another way for us to try and categorize and label things so they're easier for our brains to handle. I think that letting ourselves succumb to our instincts for such pattern recognition and categorization is a mistake. The world around us is more complex than that. The human experience is more nuanced than that. It's simply not a good approach.
On a related subject, I agree with the poster who said that he/she feels all acts are selfish, even selfless ones. Maybe not all people act this way, especially those we consider insane, but for me the best way I've found to act is to consider the short- and long-term results from each action, and choose the action you feel leads to the best results. Selflessness has a ton of upsides, where selfishness rarely does in my experience. Treat others with respect and consideration not because some morality says you blindly should, but because you think the outcome is optimal. That's how I live.
