The Fairy Mythology - Thomas Keightley - Bog

According to a well-known law of our nature, effects suggest causes; and another law, perhaps equally general, impels us to ascribe to the actual and efficient cause the attribute of intelligence. The mind of the deepest philosopher is thus acted upon equally with that of the peasant or the savage; the only difference lies in the nature of the intelligent cause at which they respectively stop. The one pursues the chain of cause and effect, and traces out its various links till he arrives at the great intelligent cause of all, however he may designate him; the other, when unusual phenomena excite his attention, ascribes their production to the immediate agency of some of the inferior beings recognised by his legendary creed.
