Clairvoyance
Clairvoyance is the power, real or supposed, which some people claim, of being able to see, while under the influence of mesmerism, events which are taking place at spots far distant from the body, and of which, under ordinary conditions, the clairvoyant could have no knowledge of. Lately clairvoyants have professed to be able to penetrate the inner consciousness of another person and read his intentions, and even forecast his future actions. But the whole theory of clairvoyance seems to have little, if any, scientific basis.
