"I can hypnotize a man -- without his knowledge or consent -- into committing treason against the United States." "Is hypnosis dangerous? It can be. Under certain circumstances, it is dangerous in the extreme. It has even been known to lead to murder. Given the right combination of hypnotist and subject, hypnosis can be a lethal weapon." "The key to creating an effective spy or assassin rests in splitting a man’s personality, or creating multipersonality, with the aid of hypnotism.... This is not science fiction. ... I have done it." "During World War II, I worked this technique with a vulnerable Marine lieutenant I’ll call Jones. Under the watchful eye of Marine intelligence I split his personality into Jones A and Jones B. Jones A, once a 'normal' working Marine, became entirely different. He talked communist doctrine and meant it. He was welcomed enthusiastically by communist cells, and was deliberately given a dishonorable discharge by the Corps (which was in on the plot) and became a card-carrying party member. All I had to do was hypnotize the whole man, get in touch with Jones B, the loyal American, and I had a pipeline straight into the Communist camp."
