From Publishers Weekly
This long, dense novel, a bestseller in the author's native Norway, offers a summary history of philosophy embedded in a philosophical mystery disguised as a children's book-but only sophisticated young adults would be remotely interested. Sophie Amundsen is about to turn 15 when she receives a letter from one Alberto Knox, a philosopher who undertakes to educate her in his craft. Sections in which we read the text of Knox's lessons to Sophie about the pre-Socratics, Plato and St. Augustine alternate with those in which we find out about Sophie's life with her well-meaning mother. Soon, though, Sophie begins receiving other, stranger missives addressed to one Hilde Moller Knag from her absent father, Albert. As Alberto Knox's lessons approach this century, he and Sophie come to suspect that they are merely characters in a novel written by Albert for his daughter. Teacher and pupil hatch a plot to understand and possibly escape from their situation; and from there, matters get only weirder. Norwegian philosophy professor Gaarder's notion of making a history of philosophy accessible is a good one. Unfortunately, it's occasionally undermined by the dry language he uses to describe the works of various thinkers and by an idiosyncratic bias that gives one paragraph to Nietzsche but dozens to Sartre, breezing right by Wittgenstein and the most influential philosophy of this century, logical positivism. Many readers, regardless of their age, may be tempted to skip over the lessons, which aren't well integrated with the more interesting and unusual metafictional story line. Author tour.

YA?From the opening Goethe quotation to the closing discussion of the big bang theory, this is an extraordinary, exciting, provocative book that has been a bestseller in Europe. Gaarder presents a didactic history of philosophical thought as part of a fictional mystery story that both pulls readers along and breaks up the "heavy" explanations into manageable parts. Yet the plot is itself a philosophical conundrum, not resolved until the aftermath of a hilarious, disturbing garden party in celebration of both Midsummer's Eve and the 15th birthday of the protagonist, a suburban Norwegian teenager. And even then, the mystery, like the human mystery, is not really resolved, and leaves readers wanting to know more. Gaarder pulls off the difficult feat of blending philosophy and entertainment in a way that will capture YAs' interest and make them eager to explore further.?Judy McAloon, Potomac Library, Prince William County, VA

From Library Journal
This novel has already been a best seller in Scandinavia and Germany, and though it is markedly different from the prototypical American best seller, it should also do well here. The framework of the story is the receipt by a 14-year-old girl of mysterious letters that present her with a history of Western philosophy, from the pre-Socratics through Jean-Paul Sartre. After reading them, Sophie is prompted to ask questions and to think analytically. She also tries to discover their source and other manifestations, such as the puzzling postcards a Norwegian UN soldier in Lebanon sends to his nearly 15-year-old daughter. Adults and mature teens will appreciate the mystery as well as the philosophy lessons found in this first novel by a Norwegian high school philosophy teacher. Recommended for most collections.

Sophie's World is sheer delight. How I wish I'd had it during my college freshman survey of philosophy!

From Kirkus Reviews
What if we were all just characters from a book written by Major Albert Knag as a philosophical present for his daughter Hilde's 15th birthday? This is the question that Sophie Amundsen must ask as she tackles the history of philosophy in what begins as a personalized correspondence course for which she never signed up. Coming home from school one day, Sophie finds questions in her mailbox, followed by typewritten pages about philosophy. She also gets strange birthday cards apparently intended for a Hilde Mller Knag in Lillesand, whom she has never met. Through these unusual circumstances, Sophie embarks on the study of philosophy with Alberto Knox--a middle-aged mystery man in a beret--only to discover that she is nothing more than the fictional heroine of a novel (called Sophie's World) about the history of philosophy. Hilde, on the other hand, whom we meet halfway through the book, appears to be a real girl whose father has written a novel entitled Sophie's World. She in turn learns about philosophy by reading about Sophie's study of philosophy, never suspecting that she is merely a character in a book--Sophie's World--written by a philosophy teacher named Jostein Gaarder to teach teenagers the beauty of philosophical discourse. In this long, self- referential novel (to use the word loosely), Gaarder presents philosophy in a clear, cogent way, using Sophie's and Hilde's experiences to illustrate his points. The reader who is expecting something other than a creative textbook, however, will be disappointed. Maybe Gaarder can fool Norwegian youths into learning philosophy, but savvy American kids won't be so easily hoodwinked. Index. (Philosophy/Fiction.

I found this book to be very engaging. It’s a philosophy history lesson in a very digestible form. I'm sure the book has its critics amongst true philosophy experts for its over simplification, but if you are unknowledgeable (like me before I read this book)and you have an interest in the subject, I highly recommend this book as a good primer.

Interesting for those interested in the history of philosophy. It's like an introductory course in the package of a novel, so a sweet pill to swallow.
