We make ’em up as we go along

“The older mythic orders gave authority to their symbols by attributing them to gods, to culture heroes, or to some such high impersonal force as the order of the universe; and the image of society itself, thus linked to the greater image of nature, became a vessel of religious awe. Today we know, for the most part, that our laws are not from God or from the universe, but from ourselves; are conventional, not absolute; and that in breaking them we offend not God but man. Neither animals nor plants, not the zodiac or its supposed maker, but our fellows have now become the masters of our fate and we of theirs.” – Joseph Campbell, The Masks of God: Occidental Mythology
