Anyone who sets about hypnotizing half sceptically, who may perhaps seem comical to himself in this situation, and who reveals by his expression, his voice and his bearing that he expects nothing from the experiment, will have no reason to be surprised at his failures, and should rather leave this method of treatment to other physicians who are able to practise it without feeling damaged in their medical dignity, since they have convinced themselves, by experience and reading, of the reality and importance of hypnotic influence
— Sigmund Freud
