Influential statements of emotivism were made by
C. K. Ogden and
I. A. Richards in their 1923 book on language,
The Meaning of Meaning, and by
W. H. F. Barnes and
A. Duncan-Jones in independent works on ethics in 1934. However, it is the later works of Ayer and especially Stevenson that are the most developed and discussed defenses of the theory.
A. J. Ayer A. J. Ayer's version of emotivism is given in chapter six, "Critique of Ethics and Theology", of
Language, Truth and Logic. In that chapter, Ayer divides "the ordinary system of ethics" into four classes: • "Propositions which express definitions of ethical terms, or judgements about the legitimacy or possibility of certain definitions" • "Propositions describing the phenomena of moral experience, and their causes" • "Exhortations to moral virtue" • "Actual ethical judgments" He focuses on propositions of the first class—moral judgments—saying that those of the second class belong to science, those of the third are mere commands, and those of the fourth (which are considered in
normative ethics as opposed to
meta-ethics) are too concrete for ethical philosophy. While class three statements were irrelevant to Ayer's brand of emotivism, they would later play a significant role in Stevenson's. Ayer argues that moral judgments cannot be translated into non-ethical, empirical terms and thus cannot be verified; in this he agrees with
ethical intuitionists. But he differs from intuitionists by discarding appeals to intuition as "worthless" for determining moral truths, since the intuition of one person often contradicts that of another. Instead, Ayer concludes that ethical concepts are "mere pseudo-concepts": Ayer agrees with
subjectivists in saying that ethical statements are necessarily
related to individual attitudes, but he says they lack
truth value because they cannot be properly understood as
propositions about those attitudes; Ayer thinks ethical sentences are
expressions, not
assertions, of approval. While an assertion of approval may always be accompanied by an expression of approval, expressions can be made without making assertions; Ayer's example is boredom, which can be expressed through the stated assertion "I am bored" or through non-assertions including
tone of voice,
body language, and various other verbal statements. He sees ethical statements as expressions of the latter sort, so the phrase "Theft is wrong" is a non-propositional sentence which is an expression of disapproval but is not equivalent to the proposition "I disapprove of theft". Having argued that his theory of ethics is noncognitive and not subjective, he accepts that his position and subjectivism are equally confronted by
G. E. Moore's argument that ethical disputes are clearly genuine disputes and not just expressions of contrary feelings. Ayer's defense is that all ethical disputes are about
facts regarding the proper application of a
value system to a specific case, not about the value systems themselves, because any dispute about values can only be resolved by judging that one value system is superior to another, and this judgment itself presupposes a shared value system. If Moore is wrong in saying that there are actual disagreements of
value, we are left with the claim that there are actual disagreements of
fact, and Ayer accepts this without hesitation:
C. L. Stevenson Stevenson's work has been seen both as an elaboration upon Ayer's views and as a representation of one of "two broad types of ethical emotivism." An
analytic philosopher, Stevenson suggested in his 1937 essay "The Emotive Meaning of Ethical Terms" that any ethical theory should explain three things: that intelligent disagreement can occur over moral questions, that moral terms like
good are "magnetic" in encouraging action, and that
the scientific method is insufficient for verifying moral claims. Stevenson's own theory was fully developed in his 1944 book
Ethics and Language. In it, he agrees with Ayer that ethical sentences express the speaker's feelings, but he adds that they also have an
imperative component intended to change the listener's feelings and that this component is of greater importance. Where Ayer spoke of
values, or fundamental psychological inclinations, Stevenson speaks of
attitudes, and where Ayer spoke of disagreement of
fact, or rational disputes over the application of certain values to a particular case, Stevenson speaks of differences in
belief; the concepts are the same. Terminology aside, Stevenson interprets ethical statements according to two patterns of analysis.
First pattern analysis Under his first pattern of analysis an ethical statement has two parts: a declaration of the speaker's attitude and an imperative to mirror it, so "'This is good' means
I approve of this; do so as well." The first half of the sentence is a proposition, but the imperative half is not, so Stevenson's translation of an ethical sentence remains a noncognitive one. Imperatives cannot be
proved, but they can still be
supported so that the listener understands that they are not wholly arbitrary: The purpose of these supports is to make the listener understand the consequences of the action they are being commanded to do. Once they understand the command's consequences, they can determine whether or not obedience to the command will have desirable results.
Second pattern analysis Stevenson's second pattern of analysis is used for statements about
types of actions, not specific actions. Under this pattern, In second-pattern analysis, rather than judge an action directly, the speaker is evaluating it according to a general principle. For instance, someone who says "Murder is wrong" might mean "Murder decreases happiness overall"; this is a second-pattern statement which leads to a first-pattern one: "I disapprove of anything which decreases happiness overall. Do so as well."
Methods of argumentation For Stevenson, moral disagreements may arise from different fundamental attitudes, different moral beliefs about specific cases, or both. The methods of moral argumentation he proposed have been divided into three groups, known as
logical,
rational psychological and
nonrational psychological forms of argumentation. Logical methods involve efforts to show inconsistencies between a person's fundamental attitudes and their particular moral beliefs. For example, someone who says "Edward is a good person" who has previously said "Edward is a thief" and "No thieves are good people" is guilty of inconsistency until he retracts one of his statements. Similarly, a person who says "Lying is always wrong" might consider lies in some situations to be morally permissible, and if examples of these situations can be given, his view can be shown to be logically inconsistent. Rational psychological methods examine facts that relate fundamental attitudes to particular moral beliefs; the goal is not to show that someone has been inconsistent, as with logical methods, but only that they are wrong about the facts that connect their attitudes to their beliefs. To modify the former example, consider the person who holds that all thieves are bad people. If she sees Edward pocket a wallet found in a
public place, she may conclude that he is a thief, and there would be no inconsistency between her attitude (that thieves are bad people) and her belief (that Edward is a bad person because he is a thief). However, it may be that Edward recognized the wallet as belonging to a friend, to whom he promptly returned it. Such a revelation would likely change the observer's belief about Edward, and even if it did not, the attempt to reveal such facts would count as a rational psychological form of moral argumentation. Non-rational psychological methods revolve around language with psychological influence but no necessarily logical connection to the listener's attitudes. Stevenson called the primary such method "'persuasive,' in a somewhat broadened sense", and wrote: Persuasion may involve the use of particular emotion-laden words, like "democracy" or "dictator", or hypothetical questions like "What if everyone thought the way you do?" or "How would you feel if you were in their shoes?" ==Criticism==
