"The coin has vanished! [note...this is where the first group STOPS thinking. For them, magic is all about the first line] Is there anything in the other hand? NO! Is there any sleeves involve--NO! WHAT! HOW DID HE/SHE DO IT!!!"
They know it is possible to seemingly vanish a coin. Why, if I had a coin in my hand, asked you to close your eyes and then, put the coin away and asked you to open your eyes again, the coin seems to have vanished! The effect seems impossible! But the experience does not. Why? Because their brains can dream up possible methods to the trick. However if I do the most amazing false transfer ever and pocket the coin when they weren't seeing, the coin has vanished and now, even if they check my hand they won't find it. Now, the EXPERIENCE becomes truly impossible. Now, even if I TELL them I used sleight of hand, their brains cannot accept that as a solution because, after all, MY HANDS WERE BOTH EMPTY! So the experience remains impossible. Even the sleight of hand the magician claims to use seems impossible! What can be a better achievement for a magician? I am not claiming I have achieved that yet but, yeah...I'd like to achieve it. Just my performance-style and persona.
@Lord Magic , reading this (in combination with other posts you have made) gives me a distinct impression that you define magic as having a method that is not discoverable and you are seeking to "fool" your audience with a "trick" that results in "bewilderment" about the method. Nobody likes to be a fool, to be tricked or to be bewildered. You are approaching magic on an analytical level as a magician. We care about methods, your audience cares about being entertained. I suspect your presentation is limited to explaining what you are doing -- what Eugene Burger called narrating the adventures of the props in the hands of the magician -- along with a lot of unnecessary "filler." The issue is that you aren't engaging your audience on an level other than the "watch, see and try to figure it out." To truly entertain as a magician (or a mentalist) you have to engage your audience's imagination, emotions, intellect, etc. It is not "look at what I can do and try to figure it out" but "enjoy something that engages you on multiple levels." A good magician doesn't need a method the audience can't figure out, a good magician needs a presentation that makes the audience not care about the method.
It's all fine as long as there's no blatant harmful lying. Harmful as in, if you are a mentalist, nobody should say you are God...and even if they do, say if your performance WAS that amazing (which is good, congrats

)...you mustn't keep quiet and continue to let them think you are God. Because now you haven't just let them form their own conclusions...by not telling them you are not God EVEN AFTER THEY CLAIMED THAT YOU ARE...you are going the wrong way about strengthening their ideas and wrongly popularising yourself.
Your logic has an internal inconsistency. For magic, you believe your audience is sophisticated enough to believe that it is all an illusion but for mentalism you believe that people will think you have psychic god-like powers. In performing mentalism, the smaller the claim the larger the reaction. I see the inherent deception in magic or mentalism only harmful if it harms the spectator (e.g. believing they have a hex put on the, believing they have to pay money to have a "spell" reversed, etc.). Merely encouraging belief in an ability shown in a series of demonstrations is not harmful -- just like watching a movie isn't harmful.
Mentalism is more accurately described as employing systems, rather than executing methods.
A system can be a method -- one ahead, multiple outs, suggestion, lying, multiple meaning statements, dual reality, etc. Although the way you perform mentalism is limited to systems, I disagree that all mentalism must be limited to systems. Annemann, Waters, Leslie, Maven, Banachek and Philpott all employ methods.
We must agree to disagree because clearly, your vision of magic as an art and my vision of magic as an art do not intersect anywhere. But that's okay, both the views are correct in their own place...I believe no vision can be 'wrong'...they are all right in certain fixed contexts. So as I said, let's just agree to disagree
[Takes out soapbox, stands up on it]
I think the idea that there is no right or wrong opinions is wrong. One opinion has to necessarily be better. Saying that you agree to disagree all too often is an easy out to avoid thinking critically about your own opinions and beliefs and developing the skills to analyze and argue (in the classic rhetorical sense, not the yelling and screaming sense) about someone else's opinion.
[Steps down and puts soapbox away]
Specifically what Ortiz writes about the difference between intellectual belief (which we cannot achieve) and emotional belief (which we must achieve if magic is to be taken seriously as an art). The people asking if it was really magic don't intellectually believe it might be magic. They are looking for reassurance against an emotional belief that they find subconsciously disturbing.... It is your job, as an artist, to "discomfort" your audience.
I'm not sure about Darwin's ideas about causing "discomfort." I think there has to be a dissonance between the intellectual "magic doesn't exist" and the perceptual "I just saw something impossible" and the emotional "I want to believe." But that dissonance doesn't need to generate discomfort. Rather, it can be used to generate a variety of emotions and reactions depending on the presentation.
