Back of this idea for profiles of presidents who came to grips with problems that would have destroyed timed men, stands the inspiration of President Kennedy, whose own ideas on the subject act the direction of the text. The President, too, is responsible for the selection. In several instances surprising choices, for subjects of the profiles. Obvious enough:- Washington, who pulled a new nation together; Lincoln, who saved the Union; even The Odore Roosevelt, though some will question the rightness of his part in the revolution of Pasama while accepting the importance of the results. Less understandable, until the profiles are read, seems the choice of John Quincy Adams, for his courage in defeat, vilification and his opposition to the policy of patronage; Andrew Johnson, who dared to oppose punishment of the South after the Civil War; Chester Arthur, who defied the bosses and instituted a respectable Civil Service procedure. The central test is the ability to make solitary decisions -- and Bill Davidson proves his point each time.
