The manager of a fruit and vegetable shop places in his window  among the onions and carrots  the slogan: 'Workers of the world  unite!' Why does he do it? What is he trying to communicate to the world? Is he genuinely enthusiastic about the idea of unity among the workers of the world? Is his enthusiasm so great that he feels an irrepressible impulse to acquaint the public with his ideals? Has he really given more than a moment's thought to how such a unification might occur and what it would mean?
