A lucid and lively survey of rival ethical theories by one of the most influential moral philosophers of the century. R.M. Hare's main theme is that objectivity in moral thinking unwittingly makes assumptions that link us to particular cultures and languages. Hare posits that an objective moral prescription, as Kant saw, is one upon which all rational thinkers can agree, regardless of background. 184 pp.
From Hare's final years, this is a series of lectures he gave, plus 1 essay on the relation of Kant to utilitarianism. A good summary of his mature views on meta-ethics.
