It is instructive to compare superstition with science. Mythology is the term used to designate the superstitions of the ancients. Folk-lore is the term used to designate the superstitions of the ignorant of today. Ancient mythology has been carefully studied by modern thinkers for purposes of trope and simile in the embellishment of literature, and especially of poetry; then it has been investigated for the purpose of discovering its meaning in the hope that some occult significance might be found, on the theory that the wisdom of the ancients was far superior to that of modern men.
