What really happens is that the story-maker proves a successful 'sub-creator'. He makes a Secondary World which your mind can enter. Inside it, what he relates is 'true': it accords with the laws of that world. You therefore believe it, while you are, as it were, inside. The moment disbelief arises, the spell is broken; the magic, or rather art, has failed. You are then out in the Primary World again, looking at the little abortive Secondary World from outside.
J. R. R. TolkienThe stars are far brighter Than gems without measure, The moon is far whiter Than silver in treasure; The fire is more shining On hearth in the gloaming Than gold won by mining, So why go a-roaming? O! Tra-la-la-lally Come back to the Valley.
J. R. R. TolkienThen Morgoth stretching out his long arm towards Dor-lomin cursed Hurin and Morwen and their offspring, saying: 'Behold! The shadow of my thought shall lie upon them wherever they go, and my hate shall pursue them to the ends of the world.
J. R. R. TolkienCold be hand and heart and bone, and cold be sleep under stone: never more to wake on stony bed, never, till the Sun fails and the Moon is dead. In the black wind the stars shall die, and still on gold here let them lie, till the dark lord lifts his hand over dead sea and withered land.
