There follows a long and rather difficult argument to show that the world is, in itself, eternal. The former discussion on this point had only shown that the gods would not destroy it. This shows that its own nature is indestructible. The arguments are very inconclusive, though clever, and one wonders why the author is at so much pains. Indeed, he is so earnest that at the end of the chapter he finds it necessary to apologize to the Kosmos in case his language should have been indiscreet. The reason, I think, is that the Christians were still, as in apostolic times, pinning their faith to the approaching end of the world by fire.[190:1] They announced the end of the world as near, and they rejoiced in the prospect of its destruction. History has shown more than once what terrible results can be produced by such beliefs as these in the minds of excitable and suffering populations, especially those of eastern blood. It was widely believed that Christian fanatics had from time to time actually tried to light fires which should consume the accursed world and thus hasten the coming of the kingdom which should bring such incalculable rewards to their own organization and plunge the rest of mankind in everlasting torment. To any respectable Pagan such action was an insane crime made worse by a diabolical motive. The destruction of the world, therefore, seems to have become a subject of profound irritation, if not actually of terror. At any rate the doctrine lay at the very heart of the _perniciosa superstitio_, and Sallustius uses his best dialectic against it. The title of Chapter XVIII has a somewhat pathetic ring: 'Why are _Atheïai_'--Atheisms or rejections of God--'permitted, and that God is not injured thereby?' Θεὸς οὐ βλάπτεται. 'If over certain parts of the world there have occurred (and will occur more hereafter) rejections of the gods, a wise man need not be disturbed at that.' We have always known that the human soul was prone to error. God's providence is there; but we cannot expect all men at all times and places to enjoy it equally. In the human body it is only the eye that sees the light, the rest of the body is ignorant of the light. So are many parts of the earth ignorant of God. Very likely, also, this rejection of God is a punishment. Persons who in a previous life have known the gods but disregarded them, are perhaps now born, as it were, blind, unable to see God; persons who have committed the blasphemy of worshipping their own kings as gods may perhaps now be cast out from the knowledge of God. Philosophy had always rejected the Man-God, especially in the form of King-worship; but opposition to Christianity no doubt intensifies the protest.
