Gregg is in the business of classifying and tinkering with the way seriously mentally ill people are treated and pigeonholed. Advice being given by people who don't know the answers, especially when it comes to the suicidal, is incredibly irresponsible.

You know that feeling you get when something is broken and you see someone trying to fix it, and you know you can do better, and you want to push them out of the way and give your own advice, because you're sure yours is the best way? You just know it? That has been the MO of psychology. A long line of men and woman pricking up their fingers and saying, I've an idea, try this. On live, human subjects. Think I'm being overly dramatic? Look at his frikken tree of knowledge model. It's like this giant pantomime admission of this failure, but then goes on to say that his model -- unification of all the nonsense -- is the light in the darkness. His model is like the epitome of what all pseudo sciences attempt -- to first suspend disbelief and criticism with a cheeky wink towards an indirect admission of nonsense, then to about turn and pile themselves upon genuine physical sciences and claim, not only to be a part, but to be a vital piece of the puzzle. It's like some L. Ron Hubbard type shit. It's incredible really. The realm of psychology is full of people like him. It is theoretical anthropology at best. At worst it is malpractice.
