First of all the tramp has no values; everything is the same; good and bad do not exist for him; and because of that, or in connection with that, he has no discipline. The lunatic values what has no value and does not value what has value. These are the chief characteristics, not a description. The householder has at least certain values from which he can start and a certain practical attitude towards things. He knows that if he wants to eat he must work.
