We have already seen in preceding chapters that we must first define our standpoint before we can decide which is the right or left bank of a river. So it is also in the matter of abolishing and maintaining religion for the people. It can be done the moment we extend the discussion to the realm of infinity. The conception of infinity, called substance by Spinoza, monad by Leibniz, thing itself by Kant, the absolute by Hegel, is indeed necessary in order to explain anything, not only by the fourth root, but by the infinite root of the adequate reason. To that extent we are agreed that enlightenment, or understanding as we say, is not alone a struggle against religion, but also for it. In the theory of understanding acquired by philosophy, there is contained a decisive repeal of religion. Nevertheless we say with Lazarus: "The power of enlightenment and its aim are not expressed in negation, not in that which is not believed, but in that which is believed, venerated, and preserved." And yet every enlightening perception, every understanding resulting from enlightenment, is a negation. In seeking enlightenment, for instance, on understanding, it is necessary, in order to prove that it is a natural phenomenon, to deny the religious element in so far as it assumes the existence of a divine chief spirit whose secondary copy the human spirit is supposed to be. Or, in order to gain enlightenment on the nature of the universe, in order to realize that it is a truly universal universe, we are compelled to deny the existence of every "higher" world, including the religious. But if we desire to become enlightened as to how it is that religion may not alone be denied, but also preserved, we must transfer its origin from an illogical other world into the natural and logical universe. Thus religion becomes natural and nature religious. If worship is confined to the idolization of the sun or the cat, every one realizes the temporality of the matter. And if we restrict worship to the adoration of the great omnipotent spirit, every one realizes the temporality of this adoration who has acquired an accurate conception of the small human spirit. If, on the other hand, we extend religious worship to everything which has ever been venerated, or will ever be venerated, by human beings, in other words, if we extend the conception of religion to the entire universe, then it assumes a very far-reaching significance. This is the essence of enlightenment on religion: That we may at will expand or contract our conceptions, that all things are alike to the extent of representing only one nature, that all fantastical ideas, all good and evil spirits and ghosts, no matter how "supernaturally" conceived, are all natural.
