We all have seat-of-the-pants ideas of what constitutes craziness. We all know that chemically-induced misbehavior (like drunkenness) is impaired. Most of us recognize variations from normality such as senility and psychosis. Such is not good for a clinical diagnosis, but it is good for getting someone in need of help to a place where one gets help. Or at the least one can get him or her out of danger to himself or others.
Eccentricity? If one is Einstein or Picasso one can get away with it. Doing something that first seems crazy and then proves obvious is genius. Doing something that first seems crazy and then remains crazy... and then that one defends as genius even though one is certifiably mediocre is crazy.
So dressing up like Napoleon Bonaparte and making official proclamations as Emperor of France for non-theatrical reasons is crazy. Saying that the President is an incompetent fool isn't. Napoleon was not crazy; he really was a genius.
The greatest evil is not now done in those sordid "dens of crime" (or) even in concentration camps and labour camps. In those we see its final result. But it is conceived and ordered... in clean, carpeted, warmed and well-lighted offices, by (those) who do not need to raise their voices. Hence, naturally enough, my symbol for Hell is something like the bureaucracy of a police state or the office of a thoroughly nasty business concern."
