[“The Runaway Species”, by Anthony Brandt and David Eagleman, a composer and a neuroscientist,] makes a single argument, clearly and thoroughly: creativity is never the creation of something from nothing. Instead, consciously or not, people refashion things. They do this for the most part in three ways: by bending, breaking and blending. Bending involves taking something and altering a property. Breaking involves taking a whole apart and assembling something new from the fragments. And blending involves mixing multiple sources together in new ways.
