This SparkNote is wrong. Plato didn't really believe that "learning is a kind of remembering, in which the soul rediscovers a truth it knew before birth." This is a dialectical approach that Socrates uses on Meno to disprove the famous "Meno's Paradox," in which Meno asks Socrates "How will you look for virtue if you do not know what it is? If you should meet with it, how will you know that this is the thing you did not know?" I can't believe that SparkNotes would let inaccurate information like this be part of the foundation for another text.
