From another point of view, it must be added that if men were really forced to project their own image into things, then the first sacred beings ought to have been conceived in their likeness. Now anthropomorphism, far from being primitive, is rather the mark of a relatively advanced civilization. In the beginning, sacred beings are conceived in the form of an animal or vegetable, from which the human form is only slowly disengaged. It will be seen below that in Australia, it is animals and plants which are the first sacred beings. Even among the Indians of North America, the great cosmic divinities, which commence to be the object of a cult there, are very frequently represented in animal forms.[131] "The difference between the animal, man and the divine being," says Réville, not without surprise, "is not felt in this state of mind, and generally it might be said that _it is the animal form which is the fundamental one_."[132] To find a god made up entirely of human elements, it is necessary to advance nearly to Christianity. Here, God is a man, not only in the physical aspect in which he is temporarily made manifest, but also in the ideas and sentiments which he expresses. But even in Greece and Rome, though the gods were generally represented with human traits, many mythical personages still had traces of an animal origin: thus there is Dionysus, who is often met with in the form of a bull, or at least with the horns of a bull; there is Demeter, who is often represented with a horse's mane, there are Pan and Silenus, there are the Fauns, etc.[133] It is not at all true that man has had such an inclination to impose his own form upon things. More than that, he even commenced by conceiving of himself as participating closely in the animal nature. In fact, it is a belief almost universal in Australia, and very widespread among the Indians of North America, that the ancestors of men were beasts or plants, or at least that the first men had, either in whole or in part, the distinctive characters of certain animal or vegetable species. Thus, far from seeing beings like themselves everywhere, men commenced by believing themselves to be in the image of some beings from which they differed radically.
