Nietzsche Explains The Herd Mentality.
"All the sick and sickly instinctively strive after a herd organization as a means of shaking off their dull displeasure and feeling of weakness...for one should not overlook this fact: the strong are as naturally inclined to separate as the weak are to congregate." -- Friedrich Nietzsche, On The Genealogy Of Morality, 1887.
