I have already indicated that these perceptions appear to depend upon the _impersonal_ consciousness, and that the impressions thus perceived are transmitted to the personal consciousness in a given form analogous to that of dream perceptions—that is to say, in a dramatic form, with a concrete and symbolical setting. The impersonal consciousness seems, therefore, to be affected in a vague, general manner: the perceptions only assume an appearance of precision in those strata of the consciousness, where the notion of personality is determined. Hence the following conclusions, which I only give as probabilities: (1) that the notion of personality is susceptible of diverse degrees; (2) that the impressions perceived by the general consciousness are agreeable or disagreeable—that is to say, only impart to the personal consciousness a very vague message, moral comfort or indefinable discomfort; that, in rarer cases, the transmitted message is more precise, and takes the form of a detailed hallucination; (3) that, if telepathy exists, the general consciousness is capable of being affected by channels other than those of the ordinary senses, which have only a value in ratio to the personal consciousness of which they are, perhaps, the condition. This last consideration brings us back to the definition which I gave a little while ago of consciousness, which is, for me, the common property of all living matter: its sensuality is limited and specified by the _senses_, is limited and specified by the personality and the will. I beg the reader to excuse me for having entered into these explanations. I wished, as I said before, to state as clearly as possible the meanings I attach to the terms I use; I have still another task to accomplish somewhat similar to the last: which is to classify medianic phenomena before studying their relations with fraud. In the first place I divide them into two wide categories, each capable of penetrating into the other, for, with the exception of luminosities, physical phenomena are rarely devoid of all meaning, and intellectual phenomena have always some fact of a physical nature as substratum. Therefore, these two categories are two _different aspects_ of the same phenomena rather than two distinct categories. If we consider the purely physical side, we have the following approximate series:— PHYSICAL PHENOMENA _Sonorous._—Raps; diverse noises. _Motor._—Normal; paranormal; parakinesis; telekinesis. _Luminous._—Amorphous; definite forms; psychic (?) photography. If we consider the form of communications, in appearance intelligent, by adhering to the mode of expression of the _intellectual_ sense of the phenomena, we have the following classification:— INTELLECTUAL PHENOMENA: ENDOSOMATIC AUTOMATISM _Muscular._—Typtology; grammatology; automatic script; automatic speaking. _Sensorial._—Visual, auditory, tactile, gustatory, olfactory phenomena.
