Both Count Solovovo and Miss Johnson lay particular stress upon the fact that the Master of Lindsay seems to have been extremely suggestible. Assuredly, that is an important point in so far as his own experiences are concerned, but the fact in nowise affects the experiences of _others_. In order to prove that suggestibility played an important part in the phenomena, it would be necessary to show that _all_ witnesses of the phenomena were suggestible--for the phenomena were seen by all in a slightly varying degree. Yet there is no evidence that many of the witnesses were suggestible at all: they did not see things Home suggested they should see, while, on the other hand, they saw things quite on their own account, when Home was busily engaged in conversation with some one else. The whole case must be made to hang together, and if "suggestion" be the key to the puzzle, it certainly fits the lock remarkably ill.[34] In summing-up his paper and the evidence contained therein, Count Solovovo concludes: "For my own part I lay it down as a general proposition ... that the testimony of several sane, honest and intelligent eye-witnesses is, broadly speaking, proof of the objectivity of any phenomenon. If there are people who maintain an opposite view, let them make experiments themselves" (p. 477). That is precisely the position I should assume: I do not believe that collective hallucinations of the kind supposed exist at spiritistic seances, except perhaps very rarely, and to special gatherings of individuals. Let me now adduce the evidence in favour of my position, and the reasons for my taking this stand so strongly. First, then, let us distinguish between _illusions_ and _hallucinations_, as this is of the very greatest importance in a discussion such as this. An illusion is a false sensory perception, the basis of which is, nevertheless, real. Thus, if an old coat in a corner of the room be mistaken for a dog, that would be an illusion. A _point de repere_ is there--a peg, upon which the mind hangs its false inferences or perceptions. An hallucination, on the other hand, is entirely a creation of the mind, and there is, in this case, no _point de repere_, which exists externally, and serves as the basis of the hallucination. Roughly speaking, this may be said to be the difference between the two. Now, let us apply this to Home's seances, and to spiritistic seances in general.
