After I give lectures-on almost any subject-I am often asked, "Do you believe in UFOs?" I'm always struck by how the question is phrased, the suggestion that this is a matter of belief and not evidence. I'm almost never asked, "How good is the evidence that UFOs are alien spaceships?"

Once, at the dreaming dawn of history -- before the world was categorized and regulated by mortal minds, before solid boundaries formed between the mortal world and any other -- fairies roamed freely among men, and the two races knew each other well. Yet the knowing was never straightforward, and the adventures that mortals and fairies had together were fraught with uncertainty, for fairies and humans were alien to each other.
