"To choose doubt as a philosophy of life is akin to choosing immobility as a means of transportation." pg 28
Does this mean to be undecided in your beliefs is to be paralyzed in life.If you live in doubt,you wont get anywhere because you dont move in any direction.
Yes, you're certainly on the right track. Choosing not to move as a method of moving will get you nowhere. It isn't a possibility because "immobility" isn't even a form of transportation. Using Pi's comparison, doubt would not even be a choice as a philosophy of life. Doubt would indicate an uncertainty of belief or an inclination not to believe, and we know this is not true in Pi's case. His life is defined by his interest in and dedication to religion and his experiences on the lifeboat.
All through the book, Pi seeks to find the meaning of life. He had to make some difficult choices while on the ocean that went against his earlier beliefs, such as eating meat and human flesh. The meaning of his whole life is determined by the story of what happened after the boat sank. He tells two different stories to the men that represent the choice between believing in God or not believing. The men choose the story with animals as "the better story", and Pi adds, "And so it goes with God". This is why doubt can't be a choice as a philosophy of life.
