“We can't stop reading. Compulsively we find ourselves reading significance into dreams (we construct a science upon it); into tea-leaves and the fall of cards. We look up at the shifting vapours in the sky, and see faces, lost cities, defeated armies. Isolated in the dark, with nothing to hear and no surfaces to touch, we hallucinate reading-matter. Our craving becomes generalized – for 'the meaning of life'. If we lived alone in a featureless desert we should learn to place the individual grains of sand in a moral or aesthetic hierarchy. We should long to find the greatest grain of sand in the world, and even (in order to find a fixed point of orientation in time as well as in space) the all-time greatest grain of sand; the grain of sand whose discovery changed our whole understanding of grains of sand for ever.”
