On the recordDecember 31, 1927
the whole project is symbolic and allegorical. Washington symbolizes the founding of our country and the stability of our institutions; Jefferson our idealism, expansion, and love of liberty; Lincoln our altruism and sense of inseparable unity; while Roosevelt typifies the soul of America--its restless energy, rugged morality, and progressive spirit. The memorial, as a whole, will idealize all that is best in our national traditions, principles, and form of government. It will symbolize maturity, stability, noble purpose, and liberty of thought and action.
