They [the paranoid], too, cannot regard anything in other people as indifferent, and they, too, take up minute indications with which these other, unknown, people present them, and use them in their ‘delusions of reference’. The meaning of their delusions of reference is that they expect from all strangers something like love. But these people show them nothing of the kind; they laugh to themselves, flourish their sticks, even spit on the ground as they go by – and one really does not do such things while a person in whom one takes a friendly interest is near. One does them only when one feels quite indifferent to the passer-by, when one can treat him like air; and, considering, too, the fundamental kinship of the concepts of ‘stranger’ and ‘enemy’, the paranoic is not so far wrong in regarding this indifference as hate, in contrast to his claim for love.
