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