Which of the philosophical questions raised in the book Sophie's World is the most interesting? What makes it more interesting or crucial than the others?
You can pick any one of many from the story, but the most central one is probably the most ordinary. "Why is Lego the most ingenious toy in the world?" is asked of Sophie for one very important reason - it sets her down a path where she learns how philosophy and its constant questioning is not separate from ordinary life or even exclusively about big ideas. This question tells her that it is a way of life and a part of life.
