I would say that o measure is to appreciate, in a double sense. Why bother trying to measure what you don't care about? And appreciation relies on perception which relies on measurement. True, not everything can be reduced to numbers, but numbers help us grasp, to understand, and thereby appreciate the wonders around us. Those who shy away from "the lab" gets an incomplete view of the world, since they wholly rely on a subjective and often faulty perception. 

It is because we appreciate and care we study paranormal phenomena or any other phenomena for that matter. Every scientists is initially drawn to a phenomena out of interest and appreciation. True later on it might be more about grants and funding, such is the reality of academics unfortunately (and more so the less public funding is granted), but still noone puts down years of their life studying anything if the don't appreciate what they study. The reason for study is a will to know as much as possible of a phenomena that intrigues you and which you care about, be it election demographics, prostate cancer, stellar nurseries or ghosts. 

The sentiment that study "blocks" learning is a vulgar take on Rousseau and an often cited "truth" among those who struggled in school for various reasons. They equate study with school, making a false dichotomy between formal and informal learning. I hated school and have the grades to prove it yet still I am a person prone to study, and actually now have a university degree (to little gain employment-wise unfortunately) and the years at university was the most mind-opening and intriguing of my life. I got the chance to study the world and realise it's wondrous nature. I learned how to learn for real (for life) at university and not for the benefit of teachers and the school, but for myself.

Appreciate the history of what once was??? That's a tautology and about the stupidest things I've seen written all categories. Mr. Ehrlich is truly a moron. He is a zealot who walks through life with blinkers because he's to lazy to actually learn and understand anything about the phenomena he claims to appreciate. I would say he does not appreciate much else than his ego and have no respect (if not even pure disrespect) for paranormal phenomena, or any other phenomena for that matter.

Why o why does these people search out the field of paranormal investigation, like flies to sugar, ripping any sense out of it and making a ludicrous endevour and a laughing matter? It's not easy keeping oneself from becoming a cynic, both when it comes to people and paranormal phenomena. 

Well, I still maintain the opinion he is atleast moronic. His whole approach is skewed (appreciation not proof) and while he has som legit criticism against in the misuse of technology, he dives head first into the darkest corners of woo. Even a blind hen and so forth…

His approach is that ghosts in unexplainable therefor we do not need proof and thereby do not need to investigate the paranormal using basic science and the only thing we can do is experience ghosts. And have fun, be entertained.

His sentence on the paranormal as entertainment is not really a criticism, rather an endorsement of using ghosts as a means of entertainment (while still "take the time to honor the ghosts of their past"). 

According to him we should all sit down (in a circle? ) and only "experience" and "honor" ghosts and not even try to understand the phenomena. He does not want investigation, he wants ghost stories. No wonder, since investigation probably would debunk most of his "stories" and "experiences".

My guess is Mr. Ehrlich got tired of not being able to produce any proof via investigation and made a logic somersault and threw out reason and instead went off the wall. Instead of actually engaging in the study of the phenomena he retracted into belief, because then he had no responsbility to have any answers, any proof, but could simply say "unexplainable" and "we shall experience not investigate ghosts" over and over again.

The whole perspective if faulty due to it's initial assumptions. And it is moronic. Change ghosts to aliens in his "manifest" and the stupidity is clear as crystal.

As for sitting down an observing objectively, that sounds all good but only if you disregard the fact that there is no objective observations. That is why we need the scientific method. Observations, experiences are always subjective and prey for presumptions, assumptions, bias, misreadings, misinterpretations. What you see is not what you get. At times you can achieve intersubjectivity but that's about as good as it gets. If you rely on yourself as the primary tool for observation you are bound to miss most of what happens and misinterpret the rest. Especially if you don't make yourself aware of that that is the case.

Of course there is nothing wrong with trying to "experience" ghosts, hey, it sure sounds fun. But in the end you are back where you started, without any answers, and in the worst case with the belief that answers and understanding are not necessary. And if I want to be entertained by ghosts and other paranormal phenomena I go to the movies, I do not not invade people's homes and businesses.

In fact to anyone actually caring about the phenomena of ghosts Mr. Ehrlich's "manifest" is downright insulting. It is a cowardly and cheap way to eat the cake while still having it. Lazy thinking, if any thinking at all.
