There is a fable about 6 blind travelers in India that come upon an elephant in their travels. One, touching its side, says the elephant is like a wall. Another, holding the tusk, says it is like a spear. A third, holding the trunk, says it is like a snake. A fourth, touching its leg, says the elephant is like a tree. A fifth, touching the ear, says it is like a fan. And the sixth, holding the tail, says it is like a rope. Each man has a limited perspective that seems contradictory to all other perspectives.
