This question got me thinking:
As I understand it, moral anti-realism is the thesis that there are no moral facts outside the individual, ones that are the case independent of the individual and its ideas.
Has anyone claimed that Nietzsche is not an anti-realist about moral disagreement?
I think the being a realist about e.g. moral disagreement (so not moral facts) is needed to retain the sense that there are values that hold independent of our state of mind. Without it, how can one even claim that someone is a good person or some life is good?
