Genius. A Very Short Introduction

Homer, Leonardo da Vinci, Mozart, Shakespeare, and Tolstoy; Curie, Darwin, Einstein, Galileo, and Newton. What do these world-famous artists and scientists have in common?- apart from the fact that their achievements predate our own time by a century or more. Most of us would probably answer: all ten possessed something we call genius, which in each instance permanently changed the way that humanity perceived the world. But pressed to be more precise, we find it remarkably hard to define genius.
