“Good artists copy; great artists steal.”
This is a favorite phrase of Jobs, but he is (mis)quoting Pablo Picasso. "Lesser artists borrow; great artists steal" is similarly attributed to Igor Stravinsky, but both sayings may well originate in T. S. Eliot's dictum http://en.wikisource.org/wiki/The_Sacred_Wood/Philip_Massinger: "Immature poets imitate; mature poets steal; bad poets deface what they take, and good poets make it into something better, or at least something different. The good poet welds his theft into a whole of feeling which is unique, utterly different than that from which it is torn."
