"I bravi artisti copiano, i grandi artisti rubano. " Pablo Picasso
L'ironia insita nella frase è che anche Picasso ha "rubato" la frase a qualcun'altro: T.S. Eliot
"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 from that from which it was torn; the bad poet throws it into something which has no cohesion."
