I am approaching seventy; it is in sight; it is only three years away. Necessarily, I must go soon. It is but matter-of-course wisdom, then, that I should begin to set my worldly house in order now, so that it may be done calmly and with thoroughness, in place of waiting until the last day, when, as we have often seen, the attempt to set both houses in order at the same time has been marred by the necessity for haste and by the confusion and waste of time arising from the inability of the notary and the ecclesiastic to work together harmoniously, taking turn about and giving each other friendly assistance - not perhaps in fielding, which could hardly be expected, but at least in the minor offices of keeping game and umpiring; by consequence of which conflict of interests and absence of harmonious action a draw has frequently resulted where this ill-fortune could not have happened if the houses had been set in order one at a time and hurry avoided by beginning in season, and giving to each the amount of time fairly and justly proper to it.
The conflict develops the plot by building suspense about whether Perseus would succeed in killing Medusa.
Perseus did not expect to be sent on such a dangerous task, but because the king wants Danae, he needs Perseus out of the way, ultimately sending Perseus on a suicide mission.
