Herd.

The instinct of the herd values the juste milieu and the average as the highest and most precious of all things: the spot where the majority is to be found, and the air that it breathes there. In this way it is the opponent of all order of rank; it regards a climb from the level to the heights in the same light as a descent from the majority to the minority. The herd regards the exception, whether it be above or beneath its general level, as something which is antagonistic and dangerous to itself. Their trick in dealing with the exceptions above them, the strong, the mighty, the wise, and the fruitful, is to persuade them to become guardians, herdsmen, and watchmen in fact, to become their head-servants: thus they convert a danger into a thing which is useful. In the middle, fear ceases: here a man is alone with nothing; here there is not much room even for misunderstandings; here there is equality; here a man's individual existence is not felt as a reproach, but as the right existence; here contentment reigns supreme. Mistrust is active only towards the exceptions; to be an exception is to be a sinner.

Friedrich Nietzsche
