A man, breaking his journey between one place and another, at a third place of no name, character, population, or significance sees a unicorn cross his path and disappear. That in itself is startling, but there are precedents for this sort of mystical encounter, or rather, a choice of persuasions to put it down to fancy, until – "My god!" shouts a second man, "I must be dreaming! I thought I just saw a unicorn!" At which point a dimension is added which makes the experience as alarming as it will ever be. A third witness, you understand, adds no new dimension, only spreads it thinner, and a fourth thinner still, and the more witnesses there are, the thinner it spreads and the more reasonable it becomes until it is as thin as reality – the name we give to the common experience. "Look! Look!" recites the crowd. "A horse, with an arrow in its forehead! It must have been mistaken for a deer!"
