It is however possible, by education, to entirely invert the order of these natural phenomena: suppose that the operator [hypnotist] speaks, with eac… - James Braid

In this way, we influence the muscles of physiognomy [facial expression] and it is possible for us to arouse any passion or sentiment whatsoever; the contraction of the interconnected muscles, constituting “the anatomy of expression”, evokes in the brain of the hypnotised person certain impressions just as these, in the waking state, determine the whole facial expression. It is thus merely a reversal of the usual order [of causation] between the emotions and their physical expressions.

...a peculiar condition of the nervous system, induced by a fixed and abstracted attention of the mental and visual eye, on one object, not of an exciting nature.

...during a period in history psychology was still a branch of academic philosophy. The psychological concepts developed by philosophers of mind, such as “dominant ideas” (akin to the automatic thoughts of Beck’s cognitive therapy) “habit and association” (a subjective precursor of Pavlovian conditioning), and “imitation and sympathy” (which we now call “role-modelling” and “empathy”), are repeatedly mentioned by Braid as the theoretical framework upon which his science of hypnotism, “neuro-hypnology”, was built. Braid’s friend and collaborator, Prof. William B. Carpenter, discusses the theoretical principles of this in his Principles of Mental Physiology (1889), especially in the chapter ‘Of Common Sense’ which concludes by quoting an approving letter from the philosopher John Stuart Mill sent to Carpenter in 1872. Mill agrees with Carpenter’s contention that “common sense”, by which he means a kind of intellectual intuition analogous to the ancient Greek concept of nous, is a combination of innate and acquired judgements, which have a “reflexive” or “automatic” quality and appear to consciousness as “self-evident” truths.
