“Consider when, on a voyage, your ship is anchored; if you go on shore to get water you may along the way amuse yourself with picking up a shellfish, or an onion. However, your thoughts and continual attention ought to be bent towards the ship, waiting for the captain to call on board; you must then immediately leave all these things, otherwise you will be thrown into the ship, bound neck and feet like a sheep. So it is with life. If, instead of an onion or a shellfish, you are given a wife or child, that is fine.”
