A devil's advocate is someone who argues the opposite way, a person who presents, usually for the sake of argument, an opposing view which he does not himself hold. The expression comes from Medieval Latin. An 'advocatus diaboli' was a Roman Catholic Church official who had been appointed to argue the case against a proposed canonisation or beatification of a candidate for sainthood, in order to ensure that the case is examined from all sides. It was transferred to wider use in the middle of the eighteenth century.
