First of all the only folks that have "proven" there is no such thing as Psi are people already hell-bent in doing so... the opposite can be said about those who set out to prove its existence; either side referring to the other as quack science or research that was improperly done, etc.
Secondly, we have a growing myriad of technology that SCIENTISTS are referring to as being literal PK and Telepathic ability. The cynic's discount said comments in that they are applying far too much black & white logic to the claims, pointing out that the bio-physics around such things negate the "paranormal" factor... well NEWS FLASH... the majority of mystic teachings will tell you that thought is energy and any 5th grade science student understands that energy expressed is akin to physical matter in action which MUST result in some mode of final manifestation. So if I apply thought, an electric impulse, that's been amplified via technology that results in a telepathic scenario it has to have a foundation in the fact that said ability is natural and already exists. [Just watch shows like "Beyond Tomorrow" and "Future Science" to get a glimpse of such things.]
Cynics love to play semantic gymnastic games when it comes to this issue; if something goes against their point of view they take on the mantel of two-bit lawyer and start splitting hairs; this includes imposing the "super-natural" idea ala Hollywood vs. how true students of mysticism understand it -- as a form of science NOT boogiemen and other imaginary friends making things happen.
Yes, there are factions of the New Age type culture that buy into such things and even students of the occult will refer to them as delusional. Cynics tend to ignore these differences however, tossing everything into the same pile... not just Psi issues but aliens, conspiracy theories, leprechauns, God, Unicorns, et al.
How is this fair, logical, analytical or anything close to intellectual and "Scientific"?
As I've pointed out in the past, I am very much a SKEPTIC but I likewise leave a serious crack in the door, suggesting that I'm about 8% believer, simply because of the things I've seen, experienced and investigated... and given my level of background I'm pretty certain I'm not just "misreading" things, as some have insinuated.
Like everything in my life I stand in the middle of things when it comes to this issue; defending
a.) people's right to believe; and
b.) the plausibility that such things exist, just not within the parameters certain fantasiful thoughts and propaganda would impose. Then we come to the act of clarifying what is and isn't; where either point of view hosts a truth around the subject, neither being as right as they want to believe, nor as wrong as their counter-parts would like to paint them as being.
I believe I've mentioned this book before but I'll repeat myself here; if you are skeptical pick up the book "
Wisdom of the Mystic Masters" by Joseph B. Weed. Just look at the foundation exercises for memory development and cultivation of one's mental prowess and tell me how the logic behind this is invalid or even boarder line "mystical" in the sense of being non-productive, bogus, or contrary to anything a serious student of Mentalism and/or the Psychological sciences don't exploit and work with both, in their own acts of self-development and in working with patrons.
Though there are a few spiritual elements in this tome, answer for me why, if Psi is so unproven, these techniques and even those taught by Harry Loraine as mental and memory development, haven't only proven benefit but create the sense that the welder of said techniques is PSYCHIC?
Mysticism is only a name for the marriage between science, intellect and faith as it was known prior to our modern times and prior to the Roman Church's deliberate act of segregating (even damning the auspices of Science as "Witchcraft" and aspects of "Satanism")... culling out logic and science for the sake of Cult Control and public manipulation... but that's another story altogether and it don't end well
