unfeeling quotes

To each his suff'rings, all are men, Condemned alike to groan; The tender for another's pain, Th'unfeeling for his own. Yet ah! why should they know their fate? Since sorrow never comes too late, And happiness too swiftly flies. Thought would destroy their paradise. No more; where ignorance is bliss, 'Tis folly to be wise.

-Thomas Gray
