Hippolyte BernheimThinkers

Hypnosis (n.) proved ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠that a man can know what he thinks he does not: pressed hard by Bernheim, the woken subject slowly recalled everything.

Post-hypnotic suggestion (n.) shows ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠the unconscious at work: told under hypnosis to open an umbrella five minutes after waking, the man did so and could give no reason.

Suggestion (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠not everything, Freud began to suspect against Bernheim: hypnosis seemed to call up a state, not create it.
