Clairvoyance And Kindred Phenomena
A very large and very interesting class of occult or psychic phenomena
is that known under the very general classification of "Clairvoyance,"
which term we have thought it advisable to employ in this sense in this
book, notwithstanding the technical objections urged by some against
such a general usage. The term "Clairvoyance" really means "clear
seeing," or "clear sight," but its special meaning, established by long
usage, is "A power of discerning objects not perceptible to the normal
senses." When it comes to the technical use of the term by students and
teachers of psychic research and occultism, however, there is found a
confused meaning of the term, some employing it in one sense, and others
in another one. Accordingly, it is perhaps as well to explain the
particular usage adopted and followed in this book.
