Thanks to their persistence and efforts, by the end of the century hypnosis was accepted as a valid clinical technique, studied and applied in the great universities and hospitals of the day.
This trend continued into the 20th Century, although in some ways, hypnosis became imprisoned by its own respectability, as it became mired in endless academic debate about “state” or “non-state”.
On the other hand, it’s only in the last few decades that we’ve come to realise that!
Hypnosis itself hasn’t changed for millennia, but our understanding of it and our ability to control it has changed quite profoundly.
These practices tend to be for magical or religious purposes, such as divination or communicating with gods and spirits.
