Question

How did Santiago change throughout the story

Answer 1

Answer:

In some ways, Santiago does not change.  

Explanation:

But ever since he had been a child, he had wanted to know the world, and this was much more important to him than knowing God and learning about man's sins.

That quote is from early in the story.  It occurs right before Santiago tells his father that he wants to travel the world.  Santiago is full of wonder and curiosity about all kinds of things.
