Not all of us agree that we should live our lives for the good of the human race as a whole. We all have different desires and I personally cannot account for all of them. All I know is that I want to be content in life while causing other people no harm. That means not being a burden on other people, not taking the things from other people that make them content, and not ending any lives through my action or inaction. Don't you think we'd be better off with a view like that? Maybe I'm naive.
Absolutely not! The people who desire to be "king of the world" are the dangerous ones. I don't desire power or glory, I desire happiness. It's very simple and you're complicating it by injecting these hypotheticals.
No. That's one person's way of verbalizing his view on existence. I don't have to subscribe to that. I am what I am. It's inconsequential if that happens to be a soul, a computer program, or an amoeba on the back of a giant turtle. I live my life in the pursuit of happiness and then I die. I have one chance to do it right, so I try to make every moment count.
Yes, and in the case of atheists it has nothing to do with a deity. We treat other people the way we do because we personally feel it's right. Morality is subjective though. Not every atheist holds the same morals, just as not every Christian does.
Right and wrong are concepts formed by societal agreements as to what benefits the advancement of that society. Our governmental laws aren't handed down by a deity, but drafted, revised, and voted on by elected representatives said to be "of and for the people." Two people may not agree on what is right and wrong, but if the majority do then it becomes right and wrong for that society. Hence different laws in different cultures.
All I have is my family, my friends, and myself in this life.
Absolutely! And that's why I live the way I do.
The welfare of others and my own happiness is the core of my belief system.
