"For who can wonder that man should feel a vague belief in tales of disembodied spirits wandering through those places which they once dearly affected, when he himself, scarcely less separated from his old world than they, is for ever lingering upon past emotions and bygone times, and hovering, the ghost of his former self, about the places and people that warmed his heart of old?"

Happiness has to be installed in each person as a state of affairs completely cut off from the process that brought it about and, in particular, from the real situation. Man has to be affected with happiness. It is a tonality given to him. Contradiction: if one does take care to give him happiness, it is because he is a free creature--but in order to give it to him, one turns him into an object.
