Here are some famous quotes reflecting the idea that confusion often arises from a failure to deeply understand the problem:

Albert Einstein: "If you can't explain it simply, you don't understand it well enough."
John Dewey: "A problem well put is half-solved."
Charles Kettering: "A problem clearly stated is a problem half solved."
Socrates: "The beginning of wisdom is the definition of terms."
Peter Drucker: "The most serious mistakes do not arise from the wrong answers, but from asking the wrong questions."
Antoine de Saint-Exupéry: "Perfection is achieved not when there is nothing more to add, but when there is nothing left to take away."
William James: "The art of being wise is the art of knowing what to overlook."
Albert Einstein: "Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius—and a lot of courage—to move in the opposite direction."
Thomas Jefferson: "The most valuable of all talents is that of never using two words when one will do."
