Some philosophers believe in the "original thought theory," which posits that no one has ever had a thought that someone else hasn't had. Pablo Picasso promoted this with his maxim that "good artists copy but great artists steal." That is, everyone is influenced by what came before them. You could argue that nothing we create can ever truly be "new."
