Nietzsche denies absolutely that there is inherent in mankind a yearning to gather into communities. There is, he says, but one primal instinct in human beings (as there is in all other animals), and that is the desire to remain alive. All those systems of thought which assume the existence of a "natural morality" are wrong. Even the tendency to tell the truth, which seems to be inborn in every civilized white man, is not "natural," for there have been--and are today--races in which it is, to all intents and purposes, entirely absent.[8] And so it is with the so-called social instinct. Man, say the communists, is a gregarious animal and can be happy only in company with his fellows, and in proof of it they cite the fact that loneliness is everywhere regarded as painful and that, even among the lower animals, there is an impulse toward association. The facts set forth in the last sentence are indisputable, but they by no means prove the existence of an elemental social feeling sufficiently strong to make its satisfaction an end in itself. In other words, while it is plain that men flock together, just as birds flock together, it is going too far to say that the mere joy of flocking--the mere desire to be with others--is at the bottom of the tendency. On the contrary, it is quite possible to show that men gather in communities for the same reason that deer gather in herds: because each individual realizes (unconsciously, perhaps) that such a combination materially aids him in the business of self-protection. One deer is no match for a lion, but fifty deer make him impotent.[9] Nietzsche shows that, even after communities are formed, the strong desire of every individual to look out for himself, regardless of the desires of others, persists, and that, in every herd there are strong members and weak members. The former, whenever the occasion arises, sacrifice the latter: by forcing the heavy, killing drudgery of the community upon them or by putting them, in time of war, into the forefront of the fray. The result is that the weakest are being constantly weeded out and the strongest are always becoming stronger and stronger. "Hence," says Nietzsche, "the first 'state' made its appearance in the form of a terrible tyranny, a violent and unpitying machine, which kept grinding away until the primary raw material, the man-ape, was kneaded and fashioned into alert, efficient man."
