In my years and years of searching out how to Articulate what I could see but failing to have the words, I discovered G. K. Chestertons abiilty to give practical advice incredibly helpful. Like all individuals in History, he was far from perfect. But I believe everyone has something of use to offer, history is loaded with useful content for the present.
Growing up, I would to get accused of over-thinking. It was frustrating at best as I felt like I was barely thinking at all. I felt dismissed and confused. Eventually, I was told that females tend to go inwards, intake and males tend to exert (speculations, opinions, etc.). I decided that I would then speak to males as they spoke to me, so I came up with the response: No, you are not thinking enough.
This particular commentary / critique of GK Chestertons seems a practical way to identify a 'Charlatan' from someone who respects Sound Reason. I believe we all need 'rules of reasoning' to properly articulate why a thing 'feels' wrong.

"And as it is with moral good and evil, so it is also with mental clarity and mental confusion.
There is one very valid test by which we may separate genuine, if perverse and unbalanced, originality and revolt fro mere impudent innovation and bluff. The man who really thinks he has an idea will always try to explain that idea. The charlatan who has no idea will always confine himself to explaining that it is much too subtle to be explained. The first idea may really be very outree or specialist; it may really be very difficult to express to ordinary people. But because the man is trying to express it, it is most probable that there is something in it, after all. The honest man is he who is always trying to utter the unutterable, to describe the indescribable; but the quack lives not by plunging into mystery, but by refusing to come out of it.'
