As quoted in Man Creates Art Creates Man (1973) by Duane Preble, p. 14
Variant translation: Art is solving problems that cannot be formulated before they have been solved. The shaping of the question is part of the answer.
As quoted in Architecture: form, space, and order (2007) by Francis D.K. Ching, p. ix 
Context: After all, what is art? Art is the creative process and it goes through all fields. Einstein’s theory of relativity — now that is a work of art! Einstein was more of an artist in physics than on his violin.
Art is this: art is the solution of a problem which cannot be expressed explicitly until it is solved.
                                    
“Unwrapping occurs when the "solution" is explicitly built into the program from the start.”
