The Declaration of Independence and the United States Constitution are the greatest statements of human liberty ever written. They are the highest achievement of our political tradition, powerful beacons to all who strive for liberty. Taken together, these documents represent the liberating principles that America seeks to conserve for itself and proclaim to the world."If we are to restore and preserve America's principles, the truths to which we are dedicated and the common ideas that constitute us as a people, we must first rediscover them," writes Matthew Spalding, director of the B. Kenneth Simon Center for American Studies at The Heritage Foundation.And that demands that we rediscover the Declaration of Independence and the Constitution.
