Chapter VII.

As on a voyage when the vessel has reached a port, if you go out to get water it is an amusement by the way to pick up a shellfish or some bulb, but your thoughts ought to be directed to the ship, and you ought to be constantly watching if the captain should call, and then you must throw away all those things, that you may not be bound and pitched into the ship like sheep. So in life also, if there be given to you instead of a little bulb and a shell a wife and child, there will be nothing to prevent (you from taking them). But if the captain should call, run to the ship and leave all those things without regard to them. But if you are old, do not even go far from the ship, lest when you are called you make default.
