Is moral judgment a fact or just an emotional exclamation mark?
In short: A. J. Ayer, a titan of 20th-century logic, argued that saying 'stealing is wrong' isn't a statement of truth at all. To him, it was no different than shouting in a tone of horror—a mere expression of feeling rather than a verifiable fact about the world.
In his 1936 work Language, Truth and Logic, Ayer championed logical positivism, which posits that for a statement to be meaningful, it must be either logically true or empirically verifiable. Under this framework, metaphysical claims—such as 'God exists' or 'charity is good'—are not merely false; they are literally nonsense because they cannot be tested by science or logic.
Ayer applied this strictly to ethics through a theory known as emotivism. He argued that moral judgments do not add any factual content to a sentence. For example, saying 'You acted wrongly in stealing' conveys no more information than simply stating 'You stole.' By adding the word 'wrongly,' the speaker is merely evincing their personal disapproval, much like using special exclamation marks or a peculiar tone of voice.
This stance creates a sharp distinction between science and morality. While Ayer acknowledged that moral experiences are real phenomena (which belong to science), he dismissed the idea of non-empirical moral truths as 'worthless' because individual intuitions often contradict one another. He concluded that ethical concepts are 'mere pseudo-concepts,' serving only to express internal sentiments rather than objective reality.
Ayer’s influence extended far beyond the classroom; he was a prominent humanist, an MI6 agent during WWII, and a public intellectual who engaged with everyone from Soviet politics to Mike Tyson. Even in his final years, he remained a rigorous advocate for humanism and rationalism, famously noting that even if he experienced life after death, it would only weaken his 'inflexible attitude' toward the belief rather than the belief itself.
