Moral expressivism is a philosophical theory that suggests moral statements do not describe facts but express emotional attitudes or preferences. For example, when someone says, "Stealing is wrong," they are not stating a fact about stealing but rather expressing their disapproval of it. This view emphasizes that moral language is more about conveying feelings than making objective claims. According to moral expressivism, moral disagreements arise from differing emotional responses rather than factual disputes. This means that when people argue about morality, they are often expressing their values and emotions rather than debating objective truths. This perspective is often contrasted with moral realism, which holds that moral statements can be true or false based on objective criteria.
