They were two perfectly insignificant and incapable individuals, whose existence is only rendered possible through the high organization of civilized crowds. Few men realize that their life, the very essence of their character, their capabilities, and their audacities are only the expression of their belief in the safety of their surroundings. The courage, the composure, the confidence, the emotion and principle, every great and every insignificant thought, belongs not to the individual, but to the crowd: to the crowd that believes blindly in the irresistible force of its institutions and of its morals, in the power of its police and of its opinion. But the contact with pure unmitigated savagery, with primitive nature and primitive man brings sudden and profound trouble to the heart. To the sentiment of one's loneliness, to the loneliness of one's thoughts and one's sensations. To the negation of the habitual, which is safe, there is added the affirmation of the unusual, which is dangerous. A suggestion of things vague uncontrollable and repulsive, whose discomposing intrusion excites the imagination and tries the civilized nerves of the foolish and the wise alike.
