“What is meant by 'reality'? It would seem something very erratic, very undependable-now to be found in a dusty road, now in a scrap of newspaper in the street, now in a daffodil in the sun. It lights up a group in a room and stamps some casual saying. It overwhelms one walking home beneath the stars and makes the silent world more real than the world of speech-and then there it is again in an omnibus in the uproar of Picadilly.”
