“And, now we have a new problem. We looked at it every which way from Sunday, we understand the problem, how it occurred, and thought we had the solution, but the solution doesn’t work.”

“The fatal flaw,” I said. “You understand the problem? You only think you understand the problem. But you understand the problem in the terms of a solution you have already developed. Your solution doesn’t work because you misunderstand the problem.”
