Charles Stevenson is widely regarded as the founder of Ethical Emotivism, a theory in ethics that emphasizes the emotive and subjective nature of moral language.

Ethical Emotivism argues that the primary function of moral language is to express emotions, attitudes, and subjective preferences rather than to describe objective moral facts.

The naturalistic fallacy, in the context of Ethical Emotivism, refers to the error of treating moral judgments as if they were statements of objective fact, rather than recognizing their emotive and subjective nature.

Ethical Emotivism emphasizes the emotive meaning of moral terms, which refers to their capacity to evoke emotions, attitudes, and subjective responses in individuals.

Ethical Emotivism rejects the notion of objective moral truths, asserting that moral judgments are expressions of subjective emotions and attitudes rather than statements of fact.

The open question argument against Ethical Emotivism highlights the fact that moral disagreements often persist even after all relevant factual information has been considered, suggesting that moral judgments are not simply matters of objective truth or falsity.

Ethical Emotivism acknowledges that moral disagreements are a natural consequence of the subjective and emotive nature of moral judgments, rather than a sign of irrationality or a lack of moral progress.

Ethical Emotivists sometimes employ the strategy of 'persuasive definition,' where they redefine moral terms in a way that makes them appear more objective or factual, in order to influence others' moral beliefs.

Ethical Emotivism recognizes that reason can play a role in moral decision-making by helping individuals clarify their own moral preferences and values, but it does not view reason as the sole determinant of moral judgments.

The appeal to consequences argument against Ethical Emotivism contends that moral judgments can be justified by their positive or negative consequences, suggesting that moral judgments are not simply expressions of subjective emotions.

Ethical Emotivism recognizes that moral motivation is a natural human response to emotions and attitudes, rather than a result of logical reasoning or self-interest.

The subjectivist paradox in Ethical Emotivism refers to the tension between the individualistic nature of moral judgments and the existence of shared moral norms and values within a society.

Ethical Emotivism recognizes that moral judgments can serve as motivators for moral actions, but it does not claim that moral judgments always lead to moral actions.

The emotive theory of ethics is also known as Ethical Emotivism, which emphasizes the emotive and subjective nature of moral language and judgments.
