Why is it significant that Pi is blind when he meets the Frenchman?

Pi’s blindness is symbolic in many ways in the episode with the Frenchman. At the end of Life of Pi, Pi tells the Japanese officials that they would believe in the man-eating island if they had seen it, and thus ties belief to sight. Without sight, belief is much more difficult—so much so that Pi assumes he is hallucinating for much of his conversation with the Frenchman. But in the end he is able to believe without sight, an imperative for belief in God. His blindness is also significant because it parallels the literal darkness to the figurative darkness of the scene, which is perhaps the most disturbing of all of Pi’s ordeal.
