[all of which] determined me to consider the whole as a system of collusion or illusion, or of excited imagination, sympathy, or imitation. I therefore abandoned the subject as unworthy of farther investigation, until I attended the conversazioni of Lafontaine, where I saw one fact, the inability of a patient to open his eyelids, which arrested my attention; I felt convinced it was not to be attributed to any of the causes referred to, and I therefore instituted experiments to determine the question; and exhibited the results to the public in a few days after. – (Braid, Neurypnology (1843), p. 35; emphasis added).
Braid always maintained that he had gone to Lafontaine's demonstration as an open-minded sceptic, eager to examine the presented evidence at first hand – that is, rather than "entirely [depending] on reading or hearsay evidence for his knowledge of it" – and, then, from that evidence, form a considered opinion of Lafontaine's work. He was neither a closed-minded cynic intent on destroying Lafontaine, nor a deluded and naïvely credulous believer seeking authorization of his already formed belief.
Braid was amongst the medical men who were invited onto the platform by Lafontaine. Braid examined the physical condition of Lafontaine's magnetised subjects (especially their eyes and their eyelids) and concluded that they were, indeed, in quite a different physical state. Braid always stressed the significance of attending Lafontaine's conversazione.

== Hypnotism ==
"Modern hypnotism owes its name and its appearance in the realm of science to the investigations made by Braid. He is its true creator; he made it what it is; and above all, he gave emphasis to the experimental truth by means of which he proved that, when hypnotic phenomena are called into play, they are wholly independent of any supposed influence of the hypnotist upon the hypnotised, and that the hypnotised person simply reacts upon himself by reason of latent capacities in him which are artificially developed. Braid demonstrated that … hypnotism, acting upon a human subject as upon a fallow field, merely set in motion a string of silent faculties which only needed its assistance to reach their development. — Jules Bernard Luys (1828–1897)

=== Lafontaine ===
Braid attended two more of Lafontaine's demonstrations; and, by the third demonstration (on Saturday 20 November 1841), Braid was convinced of the veracity of some of Lafontaine's effects and phenomena (see Yeates, 2018b, pp. 56–63).

Lafontaine’s technique was a combination of physical contact, mesmeric passes, and eye-fixation. It began with operator and subject facing each other. The operator held the subject’s thumbs. Lafontaine stressed the importance of the initial physical contact, and the subsequent operator-imposition of 'mind control' once 'rapport' had been established. Although generally successful with his assistants, he was rarely successful with volunteers (only successful in "one in four or five cases"); and was, very often, forced to abandon his attempts after some 30 minutes or so of intense effort. – Yeates (2018b), p. 57.
In particular, whilst Braid was entirely convinced that a transformation from, so to speak, condition1 to condition2, and back to condition1 had really taken place, he was also entirely convinced that no magnetic agency of any sort (as Lafontaine emphatically claimed) was responsible for the (veridical) events he had witnessed at first hand. He also rejected outright the assertion that the transformation in question had "proceeded from, or [had been] excited into action by another [person]" (Neurypnology, p. 32).

=== Braid's experimentum crucis ===

Braid then performed his own experimentum crucis. Operating on the principle of Occam's Razor (that 'entities ought not to be multiplied beyond necessity'), and recognising that he could diminish, rather than multiply entities, he made an extraordinary decision to perform a role-reversal and treat the operator-subject interaction as subject-internal, operator-guided procedure; rather than, as Lafontaine supposed, an operator-centred, subject-external procedure. Braid emphatically proved his point by his self-experimentation with his "upwards and inwards squint".
The exceptional success of Braid's use of 'self-' or 'auto-hypnotism' (rather than 'hetero-hypnotism'), entirely by himself, on himself, and within his own home, clearly demonstrated that it had nothing whatsoever to do with the 'gaze', 'charisma', or 'magnetism' of the operator; all it needed was a subject's 'fixity of vision' on an 'object of concentration' at such a height and such a distance from the bridge of their nose that the desired 'upwards and inwards squint' was achieved. And, at the same time, by using himself as a subject, Braid also conclusively proved that none of Lafontaine's phenomena were due to magnetic agency.

=== "Auto-hypnotization" and "hetero-hypnotization" ===
Braid conducted a number of experiments with self-hypnotization upon himself, and, by now convinced that he had discovered the natural psycho-physiological mechanism underlying these quite genuine effects, he performed his first act of hetero-hypnotization at his own residence, before several witnesses, including Captain Thomas Brown (1785–1862) on Monday 22 November 1841 – his first hypnotic subject was Mr. J. A. Walker. (see Neurypnology, pp. 16–20.)

=== Absence of physical contact ===
The following Saturday, (27 November 1841) Braid delivered his first public lecture at the Manchester Athenæum, in which, amongst other things, he was able to demonstrate that he could replicate the effects produced by Lafontaine, without the need for any sort of physical contact between the operator and the subject.
