This is a carry-over from the comments for "if there is evil then there is a god. WHAT???? "
It has swung around to now discussing morality and its application.
Dani, your post seems to address several different issues...
1- What standard do YOU go by to determine what's morally right or wrong?
I'm assuming you mean in my daily life.
2- Because what's right for me may not be right for you
This goes back to moral relativity which I believe is not a solid basis for morality.
3- and Hitler thought what he was doing was right - So do we just let society decide what is good or evil?
This sounds like you are asking how morality should be used to govern society.
4- All throughout history man's nature has been proven to be wicked
This is actually 2 subjects original sin and human nature
5- and the reason why he needs values is often irrelevant because each man defines the values he must reach and the virtues he must practice to reach them by his own standards.
I'm not sure how you mean this. I have really tried to give this one a lot of thought and break down what you are trying to say.... Man uses individual standards to choose what he values in life and the virtues he must practice to achieve these values.
6- Without an Ultimate Authority to determine justice, how do we ever agree on what is right?
Without using god, are you asking how you and I as individuals would come to an agreement as to what is right and wrong or does this go back to laws and government?
