The 20th Century ideal of originality was based on an individual as sufficient condition of creation: “I alone originated this.” Or “the help I got arriving at this original idea could have come from any number of sources, but I alone am the one irreplaceable element.”

I hope the 21st Century ideal of originality will be based on an individual as necessary condition of creation: “Had I not been there this would not have originated. But the same is true of my fellow-collaborators.”
