The body is to everyone the proper measure of its possessions, as the
foot is of the shoe. If, therefore, you stop at this, you will keep the
measure; but if you move beyond it, you must necessarily be carried
forward, as down a precipice; as in the case of a shoe, if you go beyond
its fitness to the foot, it comes first to be gilded, then purple, and
then studded with jewels. For to that which once exceeds the fit measure
there is no bound.
