What is the theme in The Man Who Knew Infinity: A Life of the Genius, Ramanujan by Robert Kanigel?

One key theme that the author returns constantly and develops at some length in the final chapter of the book is the role and responsibility of education in society. It remains unclear how much any educational system can really be tailored to develop or even nurture genius. Geniuses, like Ramanujan, are almost by definition outside of the realm of traditional education. Still, the reader is left to wonder how different Ramanujan's life would have been if the Indian educational system were not so rigid and inhospitable to heterodox thinkers.
