It has been demonstrated that in the hypnotic condition, in ordinary somnambulism, in the dreams and vision of ordinary sleep, in reverie, and in various other subjective conditions the mind may perceive scenes and events at the moment transpiring at such a distance away or under such physical conditions as to render it impossible that knowledge of these scenes and events could be obtained by means of the senses acting in their usual manner. That is, mind under some circumstances _sees_ without the use of the physical organ of sight. Again, it has been demonstrated that some persons can voluntarily project the mind--some mind--some centre of intelligence or independent mental activity, clothed in a recognizable form, a distance of one, a hundred, or a thousand miles, and that it can there make itself known and recognized, perform acts, and even carry on a conversation with the person to whom it was sent. That is, mind can _act_ at a distance from, and independent of, the physical body and the organs through which it usually manifests itself. These propositions present an aspect of mind which the authorities in the old fields of psychology have failed to observe or to recognize; or if they have at times caught a glimpse of it they have rather chosen to close their eyes and deny altogether the phenomena which these propositions imply, because they found it was impossible to classify them in their system. It has been to a degree a repetition of the folly exhibited by Galileo's contemporaries and critics, who refused to look through his telescope lest their favorite theories of the universe should be damaged. Nevertheless, this newly studied aspect exists, and is adding greatly to our knowledge of the nature and action of mind. Still another class of unusual mental phenomena found in this outlying field of psychology is that known under the general name of automatism; and by this is meant something more than the "unconscious cerebration" and "unconscious muscular action" of the physiologists, and something quite different from that. There is, first, the class of motor automatisms, including Planchette-writing and other methods of automatic writing, drawing, painting, and kindred performances, also poetical or metrical improvisations, and trance, and so-called inspirational speaking:--Second, there are the sensory automatisms; or such as are manifested by impressions made upon the senses and which are reckoned as hallucinations. The impression of hearing a voice, of feeling a touch, or seeing a vision may be reckoned as examples of this kind of automatism.
