What is the fundamental claim of moral nihilism?

The fundamental claim of moral nihilism is that there are no objective moral truths or values. Moral nihilists believe that morality is a human construct and does not reflect any real or independent feature of the world. Therefore, statements like 'murder is wrong' or 'honesty is good' are not objectively true or false; they are simply expressions of personal or cultural preferences. Moral nihilism rejects the idea that there are universal moral standards that apply to all people at all times. It denies the existence of any moral facts, properties, or entities. This doesn't necessarily mean that moral nihilists advocate for immoral behavior; rather, it means they believe that moral judgments are ultimately meaningless because they lack any objective basis. They might still act in ways that others consider moral, but they would not believe that their actions are objectively right or wrong, only that they align with their subjective values or preferences.
