As I've said before, some folks simply want to over-complicate simplicity
MENTALISM is a psychological muse designed originally as a means by which to appeal to the matured mind of intellectual society. It entailed propositions concerning the abstract, metaphysical and surreal as well as what was being discovered about the human mind and human nature itself. The best way to "taste" what mentalism was originally, would be to allow yourself to become enveloped by the 19th and early 20th century ambiance associated with spiritualism, the theosophical and theological ideas of the day as well as the many trends popular in that era in which human endeavor was the crux; Hypnosis, the Advancement of Memory, Phrenology (which was heralded for decades as a
legit science),
You would likewise need to understand the cultural attitudes and mindset of those times and how much different they are from today and yet, there remains those elements that remain in common; most especially the human "need" to believe or to be more accurate, to have their beliefs confirmed.
Mentalism, initially at least, gave the public these things. But then we had men like Harry Kellar, who grew strongly suspicious of certain charlatan antics. Not just within the vein of things seen as Psychic or Spiritual but through the auspices of the so-call "Professors" of the day as well; snake oil salesmen who leaned on the myths of science and the dreams most shared, of being the next Thomas Edison or some innovator. It is here that the field of Mentalism really begins to take form as a "Performance Art"; first in those acts of ponderance in which the idea or essence of a thing would be presented in supposition, the artist neither confirming nor negating what is what, leaving it to the audience to decide for themselves; a rule of thumb that is still maintained by the modern mentalists who hold to the older modes of thought.
Then there were the Expose' styled performers who deliberately employed some rather ridiculous contraptions here and there, that "replicated" psychic or spiritualistic phenomena; magicians that took magic tricks and shifted their presentation towards things surreal and nothing more. Many of those effects ultimately being seen to be just corny enough to make for some great tongue-n-cheek puns -- cheap shots -- directed towards the self-professed psychic or medium or even their allied spooks. In short, the public realized that magicians were just chasing the hype and the popularity of such things and though amused, found it cheap and "carnival-like".
Sadly, the Expose' side of things took strong hold due to how Harry Houdini capitalized on it in conjunction with Congressional Inquiries pertaining to reported charlatan antics across the nation, based on Spiritualistic services. What came about, albeit slowly, was the evolution of what we see today as the Dunninger Mold -- the gentleman performer, each offering a more analytical sense of perspective, on topics of the human mind. They were not "entertainers" as most of us view such in today's world; more akin to lecturers that helped create unique manifestations or who presented peculiar demonstrations based on (mainly) scientific research and analogy. But there was more to this portrait...
Not all involved in mentalism in this era (from the 1930s and well into the early 1980s) shot for the club or college type dates. The strove to preserve the old world ideas found in the original forms of mentalism; the air of mystery and flirting with the esoteric. Most were Readers and lecturers who would occasionally do a show here and there for the sake of publicity more than ego feeding, as they frequently referred to it as being. You'll see this sort in the personage of Robert Nelson or contemporaries of our present like Richard Webster, John Riggs or Millard Longman.
Starting in the late 1960s a new consciousness was being woven within the whole of the magic community that a few wise men recognized as being the threat it has become. Said gents forming what most know as the PEA (Psychic Entertainer's Association) so as to protect Mentalism from the ravishes of magic and magicians. Of particular concern was the new cynical hard line that was rapidly coming to the fore that had one huge goal in mind when it came to this side of the craft; obliterate the more esoteric and "real" feel around what we do. To essentially diminish and destroy a legacy and art form that had been around for a bit over 100 years, simply because it leaned so closely to charlatanism and it was so "real" in how it was framed and presented, that it not only frightened the typical magic enthusiast, most couldn't perform it properly in that they were not disciplined enough to see the broader picture that went beyond doing tricks -- the psychological parameters of the craft defied them, so to speak e.g. only a limited score of folks "had what it took" to fill these shoes and that was something many magicians saw as a threat.
Slowly a silent sort of "permission" was given that revived that cornier sense of performance found in the old expose' shows of the 20's and 30's; programs began to embrace the corny because it was comical, commercial and allowed the Mentalist to overcome the boredom factor that plagued that side of magic for so very long. Problem is, a tremendous sense of "over-compensation" took root and "permission" to add in more and more "magic tricks" and calling it "mentalism" came to be along side the
disciples of rude... those fans of atheism who, for lack of a better term, are little other than bullies that work on stage that have thrown away the tact, honor, class and discipline of those that came before them. For this group, it was perfectly ok to devalue old school mentalism and rob the students of this craft of their various tools and advantages, just to get their point across -- that it's all fake! A supposition that is "their" opinion only, based on trumped up science and carefully covered up facts, not to mention general denial of the fact that a greater score of folks on this planet have faith in something vs. those that don't.
It is here, in this "abortion" now heralded as "Mentalism" that we find our new stars only one or two of whom come close to being genuine "Mentalists" in that most are magicians that do traditional magic and only toss in a bit of mentalism here and there for the hell of it... for shock value and little more.
This is but a condensed overview of what Mentalism has been, is supposed to be and the various mutations it's come to know and why. It is by no stretch a complete overview but I believe it will help remove some of the issues for confusion from the mind of those investigating things.
