How did this man come to think the elephant was "like a wall"? He fell against the animal's huge side, and it made him think of a wall.
What was the second man's opinion about the elephant? He thought the animal was "like a spear".
Account for that idea. He felt one of the elephant's tusks, and formed his opinion without going any further.
And what about the third man? The third man put his hands on the elephant's trunk and felt it all over, but as he did not go any further, he declared that the elephant was "like a snake", because it was the only thing, as far as he knew, that squirmed about as the trunk did.
What did the fourth man do? The fourth man felt the big front legs and declared the elephant was "like a tree".
Tell us about the fifth man. The fifth man happened to touch the ear. He felt all over it but nowhere else, so he said the elephant was "like a fan".
And what had the sixth man to say? The sixth man had caught hold of the elephant's tail, and when he had felt all over it, he declared the elephant was "like a rope".
What conclusion did they come to in the end? They didn't come to any conclusion. They argued and argued for a long time, and each man was stubborn and stuck to "his own opinion".
