Define Emotivism.

Emotivism is a metaethical theory that originated in the mid-20th century, notably associated with philosophers A.J. Ayer and Charles Stevenson. It asserts that ethical statements or judgments do not express objective facts but are instead expressions of individual emotions, attitudes, or subjective preferences. According to emotivism, when someone makes a moral claim, they are not making a statement about the external world's moral properties but expressing their own feelings or advocating for certain attitudes.

Emotivism can be understood through its "boo/hurrah" analogy, suggesting that saying "murder is wrong" is akin to saying "boo to murder" rather than making an objective truth claim about the inherent wrongness of murder.

This theory implies that ethical debates are not about discovering objective moral truths but are expressions of individuals persuading or influencing others based on their emotional responses to certain actions. Emotivism challenges the notion of moral objectivity and truth, emphasizing the subjective and emotive nature of ethical discourse. While it has faced criticism, particularly regarding its ability to account for moral disagreement, emotivism remains a significant theory in the landscape of metaethics.
