Rationality belongs to the cool observer, but because of the stupidity of the average man, he follows not reason, but faith, and the naive faith requires necessary illusion and emotionally potent oversimplifications which are provided by the myth-maker to keep ordinary person on course.
I say “illusion” of choice because, in many cases, the nature of their choices hardly reaches the level of will, but of merely perfunctory activity. For the most part, their desires are not too strong, they are too weak, apathetic and easily placated. They often can be tempted into doing Nothing.
