As for my statement about morality. I'll expand a little.

When I say I KNOW certain things about morality, I can break that down into two points:

1) Morality is a concept relating to improving the wellbeing of any creatures capable of having "wellbeing"
2) Certain actions and teachings contribute towards or harm the wellbeing of those creatures.

These both seem eminently true. It is the definition of the word -- or at least the only one that I think matters. If there is such a thing as morality, it is that which concerns the actions we make towards or against the wellbeing of all, er, beings.

The second point is very murky. It's undeniably true that our actions make a difference to people's wellbeing. What's murky is "what is wellbeing?" and "which actions have which effects?" Here's where we have to make, well, our best guesses. There are certain things that seem pretty obviously detrimental, like blowing people up, maiming and raping, and indoctrinating children into hatred and bigotry. Almost nobody would deny that those things are bad. Then there's an EVEN MORE complicated question of responsibility; that is, if something bad is happening that you have the power to stop, do you have moral responsibility to stop it? My answer to that is yes, but that's not exactly philosophically sound. I just can't accept that it's okay to stand by and watch from the comfort of your deck chair while a child drowns. And if that's not okay, what makes it okay when the child isn't drowning but starving, and isn't right in front of you but living on the street/at a homeless shelter/in Africa?

Does that help?
