To Expunge Lament over Death or Exile

"to study how a man can rid his life of lamentation and groaning, and saying, "Woe to me," and "wretched that I am," and to rid it also of misfortune and disappointment and to learn what death is, and exile, and prison, and poison, that he may be able to say when he is in fetters, "Dear Crito, if it is the will of the gods that it be so, let it be so"."
