No More Learning

Therefore, since to the body avail not riches, avails not
Heraldry's utmost boast, nor the pomp and pride of an empire;
Next shall you own that the mind needs likewise
nothing of these things;
Unless--when, peradventure, your armies over the champaign
Spread with a stir and a ferment and bid War's image awaken,
Or when with stir and with ferment a fleet sails forth upon ocean--
Cowed before these brave sights, pale Superstition abandon
          your mind as you gaze, Death seem no longer alarming,
Trouble vacate your bosom and Peace hold holiday in you.
