Philosopher John Locke believed that we have no innate ideas; our minds are blank slates upon which experience writes. Modern geneticists argue that we are nothing but the stage on which a play written by our genes is performed. The nature versus nurture debate is one of the oldest philosophical issues within psychology, and countless experiments tested which theory is correct. However, none have ever come close to explaining what happened to 65-year-old Nancy Noone and her twin children.
