In the same age, or earlier, Increase Mather represents apparitions as uncommonly scarce in New England, though diabolical possession and witchcraft were as familiar as influenza. It has been shown that, in nearly forty years of earnest collecting, Mr. Wodrow did not find a single supernatural occurrence which was worth investigating by the curious. Every tale was old, or some simple natural cause was at the bottom of the mystery, or the narrative rested on vague gossip, or was a myth. Today, at any dinner party, you may hear of bogles and wraiths at first or at second hand, in an abundance which would have rejoiced Wodrow. Charles Kirkpatrick Sharpe vainly brags, in Law's Memorialls, that 'good sense and widely diffused information have driven our ghosts to a few remote castles in the North of Scotland' (1819). But, however we are to explain it, the ghosts have come forth again, and, like golf, have crossed the Tweed. Now this is a queer result of science, common- sense, cheap newspapers, popular education, and progress in general. We may all confess to a belief in ghosts, because we call them 'phantasmogenetic agencies,' and in as much of witchcraft as we style 'hypnotic suggestion'. So great, it seems, is the force of language! {303} THE LOGIC OF TABLE-TURNING Bias in belief. Difficulty of examining problems in which unknown personal conditions are dominant.
