"I have often wondered," wrote Guy Duffield, "why the Roosevelts, the Rockefellers and the Kennedys wanted to go through all the agony and conflict of seeking and holding public offices.  They certainly did not need the money.  I think I have found the answer; it is self‑expression.  It has been the desire of every human heart throughout history.  A Michelangelo did it in marble; a Shakespeare with pen and ink; a Sir Christopher Wren achieved it in the more than 50 churches he designed and built."
