<P> Flogging a dead horse (alternatively beating a dead horse, or beating a dead person in some parts of the Anglophone world) is an idiom that means to continue a particular endeavour is a waste of time as the outcome is already decided . </P> <P> According to the Oxford English Dictionary, the first recorded use of the expression in its modern sense was by the English politician and orator John Bright, referring to the Reform Act of 1867, which called for more democratic representation in Parliament . Trying to rouse Parliament from its apathy on the issue, he said in a speech, would be like trying to flog a dead horse to make it pull a load . The Oxford English Dictionary cites The Globe, 1872, as the earliest verifiable use of flogging a dead horse, where someone is said to have "rehearsed that (...) lively operation known as flogging a dead horse". </P> <P> However Jay Dillon has discovered an earlier instance attributed to the same John Bright thirteen years earlier: speaking in Commons 28 March 1859, Lord Elcho (Francis Charteris, 10th Earl of Wemyss) remarked that Bright had not been "satisfied with the results of his winter campaign" and that "a saying was attributed to him (Bright) that he (had) found he was' flogging a dead horse ."' </P>
