"Yes, that would be helpful, but is not absolutely necessary. The essential step is to fill her mind with counter-suggestions." Here he launched into an exposition of the principles and potentialities of hypnotism, and was in full tide of it when Weissmann interrupted to ask:

"But suppose these phenomena actually and independently exist? Suppose that they are not illusions but objective realities, how then will your suggestion help?"

This put Tolman on his mettle. He entered into a discourse filled with phrases like "secondary consciousness," "collective hallucinations," "nerve-force," wherein, while admitting that great and good men believed in the phenomena of "spiritism," he concluded that they were overhasty in assigning causes. For his part, the realm of hallucination was boundless. "The mind has the power to create a world of its own—it often does so, and—"

Here Weissmann again broke in. "You will enroll yourself with Aksakof and Von Hartmann and Lombroso?"

"Not precisely. They admit the reality of the appearances. I do not believe that the mind has power to dematerialize objects, as in the case of your wine-glass last night, which was a trick."

"But the mind can produce a blister without external cause," said Serviss. "You hypnotic sharps have proved that it can also deaden nerves and heal skin diseases, if not bone fractures."

"Yes, we produce marvellous cures within the organism, but we draw the line at the periphery of the body. Telekinesis is to me the word of a lively fictionist."

"One is as easy to believe as the other, and Crookes, Lodge, Lombroso, Tamburini, Aksakof, Von Hartmann, all believe in the reality of these happenings," retorted Serviss. "They differ only in their explanations. One party believes them due to disembodied spirits, the other relates them to the inexplicable action of a certain psychic force generated within the sitters and acting on objects at a distance. I am not yet persuaded of the phenomena, but I am progressing. I am willing to admit that these gentlemen are entitled to a respectful hearing."

Tolman resumed his own explanation, and after several premises and general statements put a case. "For example, take automatic writing. You begin by placing a pad and pencil before the mind. That suggests writing—sets up a certain train of associated ideas. These ideas have the innate tendency to realize themselves, the will of the subject being weakened. This is why the left hand is often used. These ideas disassociate themselves from the rest of the mental organism and may, in highly developed cases, become what is called a 'secondary personality.' They may give a weak imitation of discourse. They may assume a vague resemblance to some other individual, but they can never give a full statement or a new statement. This is why all the so-called spirit communications are so fragmentary and so futile. The cure of any such state is to set up a strong current of counter-suggestion."

Weissmann asked: "Is it not extravagant to say that there can exist in the unconscious mind of a young girl, a skill so great as will enable her to draw intricate patterns, manipulate objects at a distance, and impersonate dead persons unknown to her?"
