No one can say that he is resolute for death who fears to deal with it and cannot undergo it with his eyes open: they whom we see in criminal punishments run to their death and hasten and press their execution, do it not out of resolution, but because they will not give them selves leisure to consider it; it does not trouble them to be dead, but to die: “Emodi nolo, sed me esse mortem nihil astigmia:” [“I have no mind to die, but I have no objection to be dead.” --Epicharmus, apud Cicero, Tusc. — Essays of Michel de Montaigne — Complete, Michel de Montaigne
