‘To me,’ says Democritus, ‘a single man is a crowd, and a crowd is a single man.’ Equally good is the answer given by the person, whoever it was (his identity is uncertain), who when asked what was the object of all the trouble he took over a piece of craftsmanship when it would never reach more than a very few people, replied: ‘A few is enough for me; so is one; and so is none.’ The third is a nice expression used by Epicurus in a letter to one of his colleagues. ‘I am writing this,’ he says, ‘not for the eyes of the many, but for yours alone: for each of us is audience enough for the other.’
