I had the good fortune to vacation in Spain the past few weeks. While in Barcelona, I took this photo in the Picasso Museum.
Banksy, the graffiti artist, engraved a large stone with a quote from Picasso and then crossed out Picasso's name and put his own. Both Picasso and Banksy were trying to say that one kind of creativity is presenting art in new and different ways. Picasso did this with his riffs on paintings by Velazquez and others. Banksy does this with his parodies of popular and commercial art.
It occurred to me that those of us who create tools for organizational learning and improvement also stand on the shoulders of the talented people who came before us. Kurt Lewin, Ronald Lippitt, Peter Drucker, Chris Argyris, Donald Schon, and many others, contributed the theories, tools, and techniques that are now part of every effective consultant's and trainer's storehouse. We have "stolen" their art out of respect and made it our own.
