APPENDIX 153 OUR CHANGING CONSTITUTION I THE SALIENT FEATURE OF THE CONSTITUTION Few documents known to history have received as much praise as the United States Constitution. Gladstone called it "the most wonderful work ever struck off at a given time by the brain and purpose of man." The casual reader of the Constitution will be at a loss to account for such adulation. It will seem to him a businesslike document, outlining a scheme of government in terse and well-chosen phrases, but he is apt to look in vain for any earmarks of special inspiration. To understand the true greatness of the instrument something more is required than a mere reading of its provisions.
