The security guards at the entrance of your typical mall is the new brahmin. Both flay around their hands in ritualistic nuisances. The older ritual-peddler would throw in flowers and water creatively, the new one runs a beep-beep metal detector in the air around us.
Both are pretenses to comfort the incessantly worrying minds. Our minds often wander in search of answers to questions that have no answers. and we just can't fathom the fact that some questions are plain wrong - that chasing them would never give you answers, only anxieties.
As our world gets more and more critically complex, we would see emergence of newer and newer rituals: Unique identity cards, police with guns (even if they might not know how to operate them), walls, courts, child locks, the education system based on silly exams, audit firms, research firms and most of all advertising.
Even if a rational mind realises all these institutions & acts as pretenses, one can't stop seeking consolation through them.
Long live pretenses.
