  37             Hope, he says, cherishes the soul of him who lives in
  38             justice and holiness and is the nurse of his age and the
  39             companion of his journey;--hope which is mightiest to sway
  40             the restless soul of man.
  41
  42         How admirable are his words!  And the great blessing of riches, I do
  43         not say to every man, but to a good man, is, that he has had no
  44         occasion to deceive or to defraud others, either intentionally or
  45         unintentionally; and when he departs to the world below he is not in
  46         any apprehension about offerings due to the gods or debts which he owes
  47         to men.  Now to this peace of mind the possession of wealth greatly
  48         contributes; and therefore I say, that, setting one thing against
  49         another, of the many advantages which wealth has to give, to a man of
  50         sense this is in my opinion the greatest.
  51
  52         Well said, Cephalus, I replied; but as concerning justice, what is
  53         it?--to speak the truth and to pay your debts--no more than this?  And
  54         even to this are there not exceptions?  Suppose that a friend when in
  55         his right mind has deposited arms with me and he asks for them when he
  56         is not in his right mind, ought I to give them back to him?  No one
  57         would say that I ought or that I should be right in doing so, any more
  58         than they would say that I ought always to speak the truth to one who
  59         is in his condition.
  60
  61         You are quite right, he replied.
  62
  63         But then, I said, speaking the truth and paying your debts is not a
  64         correct definition of justice.
  65
  66         CEPHALUS - SOCRATES - POLEMARCHUS
  67
  68         Quite correct, Socrates, if Simonides is to be believed, said
  69         Polemarchus interposing.
  70
  71         I fear, said Cephalus, that I must go now, for I have to look after the
  72         sacrifices, and I hand over the argument to Polemarchus and the company.
