The herd instinct is defined as the obedience of the individual to the mass, blindly and without reflection.
Nietzsche sharply criticized the herd instinct in the modern civilization : “Morality is the herd instinct” (The Gay Science)
This is also according to him a cause of the malaise of our civilization (“A gregarious animal, a being docile,sickly, mediocre, the European of today!“). The individual herd obeyed without thinking himself to be led like a sheep in a herd (Nietzsche is also against representative democracy, which disempowers citizens). But even more is the spirit of equality that underlies the herd instinct, that Nietzsche criticizes: people are not,and should not be equal. The hierarchy is inevitable, he said, and the strong should dominate the weak. In theart of obedience, the subject must override the powerful art of commanding. Against the instinct of the mass and slave morality that flows from Nietzsche urged the “free spirits” to practice aristocratic individualism, based on a moral commitment.
Herd Instinct vs Will to power
This is why the Superman, to free themselves from the herd morality, must be isolated from the community.This isolation, which will allow the construction of a new morality, is basically the path of Zarathustra, which, once freed from the dogma and confident, come down from the mountain to announce the death of God to men.
