The Antichrist · Friedrich Wilhelm Nietzsche
16.
A criticism of the _Christian concept of God_ leads inevitably to the same conclusion.--A nation that still believes in itself holds fast to its own god. In him it does honour to the conditions which enable it to survive, to its virtues--it projects its joy in itself, its feeling of power, into a being to whom one may offer thanks. He who is rich will give of his riches; a proud people need a god to whom they can make _sacrifices_.... Religion, within these limits, is a form of gratitude. A man is grateful for his own existence: to that end he needs a god.--Such a god must be able to work both benefits and injuries; he must be able to play either friend or foe--he is wondered at for the good he does as well as for the evil he does. But the castration, against all nature, of such a god, making him a god of goodness alone, would be contrary to human inclination. Mankind has just as much need for an evil god as for a good god; it doesn't have to thank mere tolerance and humanitarianism for its own existence....
What would be the value of a god who knew nothing of anger, revenge, envy, scorn, cunning, violence? who had perhaps never experienced the rapturous _ardeurs_ of victory and of destruction? No one would understand such a god: why should any one want him?--True enough, when a nation is on the downward path, when it feels its belief in its own future, its hope of freedom slipping from it, when it begins to see submission as a first necessity and the virtues of submission as measures of self-preservation, then it _must_ overhaul its god. He then becomes a hypocrite, timorous and demure; he counsels "peace of soul," hate-no-more, leniency, "love" of friend and foe. He moralizes endlessly; he creeps into every private virtue; he becomes the god of every man; he becomes a private citizen, a cosmopolitan.... Formerly he represented a people, the strength of a people, everything aggressive and thirsty for power in the soul of a people; now he is simply _the good god_.... The truth is that there is no other alternative for gods: _either_ they are the will to power--in which case they are national gods--_or_ incapacity for power--in which case they have to be good....
