"People are gregarious by necessity. Since the days of the first cave dwellers,
humans—hairless, weak, and helpless save for cunning—have survived by
joining together in groups; knowing, as so many other edible creatures have
found, that there is protection in numbers. And that knowledge, bred in the bone,
is what lies behind mob rule. Because to step outside the group, let alone to
stand against it, was for uncounted thousands of years death to the creature who
dared it. To stand against a crowd would take something more than ordinary
courage; something that went beyond human instinct."
