Universal Prescriptivism
In a series of books, especially The Language of Morals, Freedom and Reason, and Moral Thinking, Hare gave shape to a theory that he called universal prescriptivism. According to this, moral terms such as 'good', 'ought' and 'right' have two logical or semantic properties: universalizability and prescriptivity. By the former, he meant that moral judgments must identify the situation they describe according to a finite set of universal terms, excluding proper names, but not definite descriptions. By the latter, he meant that moral agents must perform those acts they consider themselves to have an obligation to perform whenever they are physically and psychologically able to do so. In other words, he argued that it made no sense for someone to say, sincerely: "I ought to do X," and then fail to do X. This was identified as a major flaw in Hare's system, as it appeared to take no account of akrasia, or weakness of the will.
Hare argued that the combination of universalizability and prescriptivity leads to a certain form of consequentialism, namely, preference utilitarianism.

Famous quotes containing the word universal:
“It is long ere we discover how rich we are. Our history, we are sure, is quite tame: we have nothing to write, nothing to infer. But our wiser years still run back to the despised recollections of childhood, and always we are fishing up some wonderful article out of that pond; until, by and by, we begin to suspect that the biography of the one foolish person we know is, in reality, nothing less than the miniature paraphrase of the hundred volumes of the Universal History.”
—Ralph Waldo Emerson (18031882)
