Mesmer was the first to propose a rational basis for the effects of hypnosis.
Although we now know that his notion of “animal magnetism”, transferred from healer to patient through a mysterious etheric fluid, is hopelessly wrong, it was firmly based on scientific ideas current at the time, in particular Isaac Newton’s theories of gravitation.
The popular image of the hypnotist as a charismatic and mystical figure can be firmly dated to this time.
Inevitably, these magical trappings led to Mesmer’s downfall, and for a long time, hypnotism was a dangerous interest to have for anybody looking for a mainstream career.
The future of hypnosis will be to fully realise the incredible potential of our natural hypnotic abilities.
