In the relations of the brain with the organs telepathy acts visibly. Man communicates with his sensory organs, such as the visual and auditory centers.
Automatism and hallucination might be easily explained as the awakening in special centers of a sensation unknown to us. Strangers as we are to the inmost perceptions of these small lower centers of consciousness, we are fully aware that a sensation, known only to them and awakened in them without our knowledge, reaches us telepathically, and creates in us the identical interpretation whatever may be the cause of the excitation of the organ.
In other words, if a memory is capable of arousing a sensation in these lower centers, we are not capable ourselves of distinguishing this sensation from that transmitted by the same organ when it is in the presence of the real image. We have thus an illusion that is like reality.
It is doubtless a modified image, as the picture produced upon a photographic plate differs from nature. But in the consciousness of the percipient this image is real and sufficiently similar to be sent to the spectator in the manner of a motion picture projection.
Experience and numerous observations of this phenomena determine that telepathy reaches not only the brain, but is quite capable under certain conditions, still unknown, of reaching the psychic element directly in its secondary centers of consciousness. From this it follows that the ego is greatly surprised to receive thus indirectly an image which it has never seen, or to execute, automatically, actions which are beyond the reach of its knowledge. That would seem to belie the axiom Nihil in intellectu quod non prius fuerit in sensu.
This proves quite simply that the sense organs can be impressed by a foreign influence. The transmitted image impresses itself first upon the secondary center and from there enters the consciousness of the percipient.
Thus telepathy explains not only hallucinations, but also suggestions come from without, automatisms, etc.
