The constructionist thesis of history states, in general, that the historian must construct a theory to explain the past. Some, including Leon Goldstein, attempt to push this formulation beyond a description of historical methodology. They argue that since the real past is inaccessible to present observation, the real past can have no relevance for historiography. The distinctions made between the present, the real past, and the historical past generate problems with the concepts of past and present knowledge, theoretical infrastructure and (...) experience, verification and truth, conflicting historical theories, and observation and knowledge. Goldstein's formulation of the constructionist thesis assumes the conflicting positions that experiential perception is paradigmatic of all methods of acquiring knowledge, and that knowledge is itself a kind of experience. As well as conflicting with commonsense views, his thesis is internally incoherent. (shrink)

Utilitarianism claims to be a rational moral theory in at least three ways. First, it claims to give us an objective standard of morality, a way of deciding moral issues, not in the light of what each of us happens to like or dislike, but on publicly verifiable grounds. Secondly, by offering only one criterion of morality it assures consistency. If we accept a system which invokes two or more independent principles, there is always the possibility of insoluble conflict. For (...) example, if we take our stand on the Ten Commandments, we cannot, without divine revelation, be sure that we shall not one day find ourselves in a situation in which we must break one or other of them; and our system gives us no guide as to which we ought to break.
