First thing’s first, this isn’t a baby book like the title makes it seem like. The full title is actually, Sophie’s World: A Novel About The History Of Philosophy. As it the title suggests the whole plot has a lot to do with philosophy. It’s about a girl named Sophie who gets a letter one day which says, “Who are you? Where does the world come from?” and before she knows it she is enrolled in a correspondence course, covering Socrates to Sartre and beyond with a mysterious philosopher. But at the same time she is receiving a separate batch of equally unusual letters. Who is Hilde? And why does her mail keep on coming to Sophie? To unravel this riddle, Sophie must make use of the philosophy she is learning. But the truth is far more complicated than she could have imagined… This book also was the 1# international bestseller. All in all, if you read this, you need to be ready for some serious thinking.
