The greatest initiators in the religious order have been the greatest creators of symbols. Prophecy, in the Biblical sense of the word, has never given divine revelation except in the form of images. And whence spring these images but from the exaltation of the religious life of the prophet which spontaneously expresses itself without? Every other conception of inspiration is anti-psychological. To the question, Whence come the life and power of symbols? we reply: From the primitive organic unity of the sentiment of piety, and of the image which translates it first to consciousness. It is the organic unity of soul and body. The greater the creative force that engenders the symbol, the stronger is this unity. It constitutes its truth because it constitutes its life. For a symbol, to be living it suffices that it should be sincere, that the feeling should not be separate from the image, nor the image from the feeling. To this cry of confidence in God, "The Lord is my rock," there is no objection, so long as this confidence is really felt, although a rock is a very poor image of God. It follows that the value of a symbol must not be measured by the nature of the image employed, but by the moral value, in the scale of feeling, of the relation in which it places us to God. It is the moral value of this relation which alone makes the intrinsic value of a religion, and which permits us to assign to it its true place in the development of humanity. The time comes, however, when the image detaches itself from the feeling that produced it, and when it fixes itself as such in the memory. In considering it in itself, reflection transforms the image into an idea more or less abstract, and takes this idea for a representation of the object of religion. But then arises the original discrepancy that we noted at the outset between the object of religion, which is transcendent, and the nature of the phenomenal image by which we attempt to represent it. Hence there is a latent contradiction in every symbolic idea. To get rid of this contradiction the understanding is obliged to eliminate from these ideas the sensible element which remains in them and renders them inadequate to their object. By progressive generalisation and abstraction, reasoning attenuates the primitive metaphor; it wears it down as on a grindstone. But, when the metaphorical element has disappeared, the notion itself vanishes in so far as it is a positive notion. There are mysterious lamps which only burn under an alabaster globe. You may thin away the solid envelope to make it more transparent. But mind you do not break it; for the flame inside will then go out and leave you in the dark.
