The Moral Life of Babies
It turns out instead that the right theory of our moral lives has two parts. It starts with what we are born with, and this is surprisingly rich: babies are moral animals.
The Moral Life of Babies
I am not saying we all live by morals. I am saying that as we are all born with the basics of morality this is reflected in the way we live. We don't have to be moral as we have free will but the fact that we make morality normative and create laws and Rights around morals we actually create moral reality by doing this.
If morality is only relative/subjective then by doing this we are contradicting ourselves by forcing everyone to conform to these norms as the very idea of relativism and subjectivism is that there are no moral truth that everyone can be forced to conform with. But rather everyone has their own moral truth.
So its the fact that we act as hostile witnesses against subjective morality and become crown witnesses for moral truths which must have some bearing on what is morlay real or not.
BUt this arguement from moral difference or disagreement is a logical fallacy. It doesn't follow that because people disagree or that morals have changed means there is no moral truths. Let me ask you do you think morality has changed for the better.
