Emotivism(redirected from boo-hurrah theory)
Also found in: Dictionary, Wikipedia.
an ethical theory based on the ideas and methodology of logical positivism. According to the theory, moral judgments and terms are neither true nor false; they are devoid of cognitive content, since they cannot be verified by experience. They are significant only to the extent that they express moral emotions (for example, the emotions of the speaker).
Viewing moral concepts as arbitrary, emotivism presents a nihilistic interpretation of morality. It gained currency between the 1920’s and 1940’s in Great Britain, Austria, and the USA. Its chief spokesmen have been A. Ayer, B. Russell, R. Carnap and H. Reichenbach.
