Nietzsche's objection to Christianity is that it caused acceptance of what he calls 'slave morality'. It is curious to observe the contrast between his arguments and those of the French philosophes who preceded the Revolution. They argued that Christian dogmas are untrue; that Christianity teaches submission to what is deemed to be the will of God, whereas self-respecting human beings should not bow before any higher Power; and that the Christian Churches have become the allies of tyrants, and are helping the enemies of democracy to deny liberty and continue to grind the faces of the poor. Nietzsche is not interested in the metaphysical truth of either Christianity or any other religion; being convinced that no religion is really true, he judges all religions entirely by their social effects. He agrees with the philosophes in objecting to submission to the supposed will of God, but he would substitute for it the will of earthly 'artist-tyrants'. Submission is right, except for these supermen, but not submission to the Christian God. As for the Christian Churches' being allies of tyrants and enemies of democracy, that, he says, is the very reverse of the truth. The French Revolution and Socialism are, according to him, essentially identical in spirit with Christianity; to all alike he is opposed, and for the same reason: that he will not treat all men as equal in any respect whatever.
