Carl Jung, the great psychoanalyst, tried to explain why so many people were fascinated by UFO phenomena. He wrote: "We are all born to believe. The eyes may be wrong, but the psyche is right. We are all looking for a perfect model of ourselves."

C. S. Lewis made the same point when he observed: “Most people, if they had really learned to look into their own hearts, would know that they do want, and want acutely, something that cannot be had in this world. There are all sorts of things in this world that offer to give it to you, but they never quite keep their promise. The longings which arise in us when we first fall in love, or first think of some foreign country, or first take up some subject that excites us, are longings which no marriage, no travel, no learning can really satisfy. I am not now speaking of what would ordinarily be called unsuccessful marriages, or holidays, or learned careers. I am speaking of the best possible ones. There was something we grasped at, in that first moment of longing, which just fades away in reality. I think everyone knows what I mean. The wife may be a good wife, and the hotels and scenery may have been excellent, and chemistry may be a very interesting job, but something has evaded us." (quoted in The Joyful Christian)
