bring on Glanvil a throng of bores--he was 'worse haunted than Mr. Mompesson's house,' he says-and Mr. Pepys found his arguments 'not very convincing.' Mr. Pepys, however, was alarmed by 'our young gib-cat,' which he mistook for a 'spright.' With Henry More, Baxter, and Glanvil practically died, for the time, the attempt to investigate these topics scientifically, though an impression of doubt was left on the mind of Addison. Witchcraft ceased to win belief, and was abolished, as a crime, in 1736. Some of the Scottish clergy, and John Wesley, clung fondly to the old faith, but Wodrow, and Cotton Mather (about 1710-1730) were singularly careless and unlucky in producing anything like evidence for their narratives. Ghost stories continued to be told, but not to be investigated. Then one of the most acute of philosophers decided that investigation ought never to be attempted. This scientific attitude towards X phenomena, that of refusing to examine them, and denying them without examination, was fixed by David Hume in his celebrated essay on 'Miracles.' Hume derided the observation and study of what he called 'Miracles,' in the field of experience, and he looked for an _a priori_ argument which would for ever settle the question without examination of facts. In an age of experimental philosophy, which derided _a priori_ methods, this was Hume's great contribution to knowledge. His famous argument, the joy of many an honest breast, is a tissue of fallacies which might be given for exposure to beginners in logic, as an elementary exercise. In announcing his discovery, Hume amusingly displays the self-complacency and the want of humour with which we Scots are commonly charged by our critics: 'I flatter myself that I have discovered an argument which, if just, will, with the wise and learned, be an everlasting check to all kinds of superstitious delusions, and consequently will be useful as long as the world endures.'
