Read the poem given below and the answer the questions that follow:
Patriotism Breathes there the man with soul so dead, Who never to himself hath said, “This is my own, my native land!” Whose heart hath ne’er within him burned As home his footsteps he hath turned From wandering on a foreign strand? If such there breathe, go, mark him well; For him no Minstrel raptures swell; High though his titles, proud his name, Boundless his wealth as wish can claim; Despite those titles, power, and pelf, The wretch, concentred all in self, Living, shall forfeit fair renown, And, doubly dying, shall go down To the vile dust from whence he sprung, Unwept, unhonored, and unsung.
What does the underlined word concentred most likely mean?
