Gaarder argues that there is more to life and existence than we can possibly understand. The point is not that Sophie and Alberto really exist somewhere but simply that if they did, we would never know it. Alberto and Sophie escape from Hilde's father. He created them, and they existed only for his daughter's amusement, but they took on an existence of their own. This returns us again to Socrates and the idea that knowing that we know nothing is the first step towards wisdom. Gaarder might be saying that we really know very little about life, and that we must always keep that in mind. Maybe we are free; maybe our every thought is determined. Either way we really have no way of knowing. What is critical is that we always raise the question. If we continually bear in mind the possibilities, then we will live our lives properly. We must make do with our ignorance and go on from there. One of the largest points of Gaarder's book is that meaning cannot be found in books. People must find meaning in their lives through living, and through asking the questions that pervade Sophie's World. Just because we are ignorant does not mean it is all right to live our lives without questioning. The opposite is true. Precisely because there are questions that we cannot definitively answer we must continue asking them—and that is what makes for a fulfilling life.
