So the arguments given for atheism so far are:
* lack of evidence for theism
* propensity for people to make up supernatural explanations
Then what good is a theistic objective moral standard? Does everyone need to be on the same page that says it is a "good" thing to kill someone due to a lack of belief?Maximizing physical harm to you is good though according to their chosen standard. In any case, there's no moral highground between the both of you.
Well if none of them are what would it matter?
Good luck with that. What is rational to one person may not be to another which is kind of the point here. I think murder is wrong. Someone else does not. That is about as basic a claim as you can make and even it can't be agreed upon.Correct. So in order to begin our inquiry about which one is real we must first be working from the moral realist perspective. It's a matter of determining which moral views corroborate the underlying facts. It's a matter of discerning which moral views are most rational.
Be compassionate, honest, courageous, diligent, etc.
Do you like the flavor of chocolate or vanilla ice cream better?
What behavior can be rationally endorsed as a universal principle to everyone?....Be compassionate, honest, courageous, diligent, etc.
Haha okay, do you like a swirl of chocolate and vanilla ice cream or strawberry ice cream better?
Is someone who likes the flavor of vanilla ice cream better than chocolate irrational?
I, personally, would find those things irrational if I wanted to be considered a good person. However, I cannot speak for someone else.Is someone irrational for believing that cruelty, dishonesty, cowardice, and laziness are morally good?
It does to that person at that moment. It may not appear rational to anyone else. They may also change their mind at a later time.If someone believes that their behavior is rational does that automatically make it so?
