Rah, Rah, RAH! by Spider Robinson
A swarm of petulant blind men are gathered around an elephant, searching him inch by inch for something at which to sneer. What they resent is not so much that he towers over them, and can see farther than they can imagine. Nor is it that he has been trying for nearly half a century to warn them of the tigers approaching through the distant grasses downwind. They do resent these things, but what they really, bitterly resent is his damnable contention that they are not blind, his insistent claim that they can open up their eyes any time they acquire the courage to do so.
